Selling Delaware Property From Out of State? Form 5403 Withholding at Settlement and How to Get Your Money Back

If you are selling Delaware property from out of state, one of the most important closing-line items to understand is Delaware’s non-resident real-estate income-tax payment. 

Many sellers still know this process as Delaware Form 5403 withholding, but Delaware has renamed the current form REW-EST, Real Estate Tax Return – Declaration of Estimated Income Tax. Delaware’s own tax-modernization materials identify REW-EST as the successor to Form 5403.

For an applicable non-resident seller, the current REW-EST generally calculates an estimated Delaware income-tax payment based on gain. For individuals and most non-corporate sellers, the current form uses 6.6% of the estimated gain; C corporations use 8.7%. 

The payment accompanies the deed before recording and is withheld from available seller proceeds. It is not a separate transfer tax and it is not automatically your final Delaware income-tax bill.

That last distinction matters. After the year of sale, an individual non-resident reports the Delaware-source transaction on the applicable PIT-NON non-resident income-tax return, claims the real-estate estimated-tax payment as a credit, and reconciles the amount against the actual Delaware tax liability. 

The 2025 PIT-NON, for example, puts REW-EST payments on Line 53 and calculates an overpayment and potential refund later in the return.

This article focuses specifically on that settlement-day process: applicability, calculation, exemptions, cash closings, documentation and getting excess withholding back.

Tax and legal disclaimer: This article provides general educational information about Delaware real-estate withholding and closing procedures. It is not individualized tax, legal or accounting advice. Tax treatment can change with ownership structure, residency, basis, prior rental use, installment-sale treatment, federal exclusions and other facts. Sellers should have their Delaware closing attorney and, where appropriate, a qualified tax professional review their transaction.

What Is Delaware Form 5403 Withholding?

“Form 5403” remains a common name among sellers, attorneys and people searching old Delaware tax materials, but it is important to use the current paperwork.

Delaware’s statutory non-resident real estate withholding rules are found in 30 Del. C. §1126, which defines a nonresident individual for this purpose and sets out the declaration and payment framework connected with recording the deed. 

The Delaware Division of Revenue now lists Form REW-EST – Real Estate Tax Return – Declaration of Estimated Income Tax on its current 2025–2026 tax forms pages. Earlier Delaware materials expressly show REW-EST as the form “formerly” numbered 5403.

The purpose has not fundamentally changed. Delaware taxes non-residents on income and gain attributable to Delaware sources, including gain associated with the ownership or disposition of Delaware real property. 

Section 1124 of Title 30 specifically treats income or gain from the disposition of an interest in Delaware real property as Delaware-source income.

The real-estate withholding regime gives Delaware a way to collect an estimated payment when the property changes hands, rather than relying entirely on an out-of-state seller to pay the state tax months later.

For an individual, 30 Del. C. §1126 requires a nonresident seller of Delaware real estate to submit the prescribed estimated-tax return or qualifying alternative declaration with the Recorder. The estimated tax and form are delivered with the deed before recording.

Most importantly, the statute expressly says the withholding section itself does not impose a new tax or determine the seller’s ultimate tax liability. It is a collection mechanism. The payment is credited to the non-resident transferor as an estimated payment.

That is why treating Delaware real estate tax withholding at closing as an unavoidable “6.6% closing tax” is misleading. The percentage is applied under the estimated-payment rules; the seller’s actual Delaware liability is resolved later.

Who Counts as a Non-Resident Seller in Delaware?

For the individual withholding statute, Delaware defines a “nonresident individual” as an individual who is not a resident individual of Delaware for the individual’s entire tax year. 

That wording also means a seller who changes residency during the year deserves special attention rather than a casual assumption based only on the address shown on the deed.

Delaware’s income-tax rules separately address part-year residents and allow specific methods for computing their Delaware tax. Residency therefore cannot reliably be determined merely by asking, “Where is the house?” The property is in Delaware by definition; the question is the seller’s tax residency and classification.

A former Delaware resident who moved to Pennsylvania, Maryland, Florida, New Jersey or another jurisdiction before selling may therefore fall within the nonresident regime, depending on when the move occurred and the seller’s status for the relevant tax year.

The current REW-EST is also broader in its ownership categories than a typical homeowner may expect. Part 2 includes boxes for:

• individual or revocable living trust;
• corporation;
• trust or estate;
• business trust;
• partnership;
• S corporation;
• limited liability company; and
• other transferors.

Entity ownership requires particular care. Separate Delaware statutes address nonresident pass-through entities and nonresident corporations. 

A nonresident pass-through entity with nonresident members may need an REW-SCH identifying members and allocating payments. The current instructions warn that failure to complete that schedule can delay processing of the members’ individual returns.

Delaware also has a separate statutory definition for a nonresident corporation under §1909. It is therefore unsafe to decide entity status by assuming that every Delaware LLC, trust or corporation is treated identically.

If the deed is held by a trust, estate, partnership, multi-member LLC or corporation, have the settlement professional establish the taxpayer classification before trying to calculate the withholding.

Table 1: When Form 5403/REW-EST May Affect a Delaware Sale

Seller or transaction	Withholding likely?	What to verify
Full-year nonresident individual selling Delaware real estate	Generally yes unless an applicable exception/exclusion applies	Residency, estimated recognized gain, Part 5 exemption
Former Delaware resident who moved during the year	Fact-specific	Part-year residency treatment and sale date
Delaware resident individual	No nonresident gain withholding if properly reported as resident	Correct residency certification
Nonresident partnership/S corporation	Potentially, for nonresident members	§1606 and REW-SCH
LLC	Depends on tax classification and members	Federal/Delaware tax classification
Corporation	Entity-specific rules apply	Resident/nonresident status and C-corp rate
Trust or estate	Fact-specific	Tax status, fiduciary treatment and current DOR instructions
Qualifying gain-exempt/excluded transaction	Payment may be zero	Correct exemption/exclusion certification
Foreclosure transaction covered by statutory exception	Special treatment	Exact statutory foreclosure/deed-in-lieu provision

The current form itself says REW-EST must be completed for all conveyances and presented at recording, while Part 5 provides the mechanism for resident and qualifying exempt situations to stop the withholding computation.

When Does Form 5403 Apply?

For an ordinary homeowner, the relevant trigger is a conveyance of Delaware real estate by a seller who falls within the state’s non-resident rules.

The Delaware statute says every nonresident individual who “sells or exchanges Delaware real estate” must file one of the prescribed declarations with the Recorder. Delaware-source income rules separately include income or gain arising from disposition of Delaware real property.

That can include far more than an owner-occupied house. Depending on the ownership and tax facts, the regime can be relevant to:

• single-family homes;
• condos and townhouses;
• rental houses;
• investment real estate;
• vacant Delaware land;
• inherited Delaware property;
• former principal residences;
• property owned through pass-through entities; and
• corporate-owned real estate.

For someone who needs to sell an inherited property in Delaware, inheritance changes the basis analysis but does not by itself mean that a later sale is outside Delaware’s real-estate withholding rules.

Likewise, a rental property sale can generate Delaware-source gain even when the landlord has lived outside Delaware for years. Sellers handling an occupied investment property may also find the site’s guide to selling a rental property with tenants in Delaware useful for the separate landlord/tenant issues.

Not every deed results in a payment, however. Current REW-EST Part 5 includes categories for resident sellers, sales exempt from gain realization, gains excluded from income, and qualifying foreclosure situations. Part 7 also addresses installment-sale treatment.

The correct framing is therefore:

The form accompanies the conveyance; whether money must actually be withheld depends on seller status, recognized gain and applicable exceptions.

How Delaware Form 5403 Withholding Is Calculated

This is where old summaries of non-resident seller withholding Delaware transactions often create unnecessary confusion.

The current REW-EST instructions establish a gain calculation. For an individual or other non-C-corporate taxpayer, Delaware currently applies 6.6% to the gain calculated for estimated-payment purposes. C corporations use 8.7%.

The current calculation in Part 6 is:

Total sales price
− selling expenses/reductions to sale price
= net sales price

Then:

Net sales price
− adjusted basis
= total estimated gain

For most taxpayers:

Estimated gain × 6.6% = Delaware estimated income tax due

For a C corporation, the form currently applies 8.7%.

Gain-Based Calculation

Suppose a nonresident individual sells a Delaware property for an illustrative $400,000.

Assume, solely for this example:

• sale price: $400,000;
• qualifying selling expenses/reductions: $24,000;
• adjusted basis: $250,000.

The REW-EST-style estimate would be:

$400,000
− $24,000
= $376,000 net sales price

$376,000
− $250,000 adjusted basis
= $126,000 estimated gain

At the current 6.6% rate for an individual:

$126,000 × 6.6% = $8,316 estimated Delaware payment

That $8,316 is not the seller’s net profit and it is not automatically the final Delaware tax liability. It is the settlement-stage estimated payment produced from the figures reported on REW-EST.

The current instructions define adjusted basis for this form as including original purchase price, non-deductible closing costs and improvements, reduced by depreciation previously taken for tax purposes.

Alternative or Default Withholding Method

Delaware law contains another important rule.

Section 1126 expressly authorizes an alternative form calculating tax at Delaware’s highest marginal individual rate on the difference between the amount realized and the net balance due on recorded liens at settlement.

Operationally, the current REW-EST also warns that when Part 6 is not completed or is incomplete, the applicable 6.6% or 8.7% will be withheld from net proceeds at settlement.

That is a major reason to establish basis before settlement.

A seller with a well-supported basis calculation should not casually arrive at closing without the information necessary to complete Part 6. A net-proceeds calculation can produce a very different closing deduction from a gain-based estimate.

It is also important not to misread this as permission for a seller to simply choose any “alternative withholding amount.” The current form does not provide a blank election allowing the transferor to select an arbitrary lower number. Any lower or zero payment must be supported by the form’s recognized calculation, exclusion, exemption or other lawful treatment.

Table 2: Form 5403/REW-EST Calculation Methods

Method	Calculation base	Documentation	Main risk
Gain calculation on current REW-EST	Net sales price less adjusted basis	Purchase records, selling costs, improvements, depreciation	Unsupported basis may produce wrong gain
Statutory amount-realized/net-lien alternative	Statutory proceeds less qualifying recorded liens	Settlement and lien/payoff records	May be materially higher than gain-based result
Current-form incomplete-Part-6 fallback	Net proceeds at settlement	Settlement ledger	Potentially significant withholding if basis work was not finished
Gain excluded/exempt	Qualifying excluded or nonrecognized gain	Facts supporting relevant tax provision	Incorrect certification can cause later tax problems
Installment method	Special Part 7 treatment	Installment-sale documentation	Later recognized gain still must be reported

Who Withholds and Remits the Tax at Closing?

The practical Delaware real estate tax withholding closing process involves several different people, and their roles should not be confused.

Legally, the seller/transferor is the taxpayer. The current instructions state that the estimated tax is paid by the transferor/seller, and the seller must sign REW-EST under penalty of perjury.

In a normal closing, the settlement attorney or settlement office typically assembles the tax information, incorporates the payment into the disbursement figures and ensures the form travels with the deed package.

But Delaware’s statute is carefully written. It says neither the buyer, title insurer, title insurance producer, settlement agent, closing attorney, lender nor real-estate broker is personally liable for the seller’s amounts required under §1126.

The statutory recording process is:

1. The applicable return/declaration and payment are prepared.
2. Payment is withheld from available seller net proceeds.
3. REW-EST and the payment accompany the deed to the Recorder.
4. The Recorder receives them before recording.
5. The Recorder accounts for and forwards collected estimated taxes to Delaware.

Under Title 9, Delaware recorders remit those collections to the Secretary of Finance no later than the twentieth day of the month following recording.

This explains why the withholding is tightly tied to settlement and recording instead of being handled like an ordinary quarterly estimated-tax voucher mailed independently months later.

Where Form 5403 Appears on the Settlement Statement

Your REW-EST payment affects the amount of money actually leaving closing with you.

Although settlement statement layouts vary, the amount may appear as a seller debit or tax-related disbursement with wording such as estimated Delaware income tax, REW-EST, real-estate capital-gain payment or similar terminology.

Do not confuse it with the other deductions between contract price and seller net.

Table 3: Illustrative Settlement Statement

Seller debit/credit	Illustrative amount	Explanation
Contract sales price	+$400,000	Gross consideration
Mortgage payoff	−$140,000	Debt being satisfied
Selling/closing expenses	−$24,000	Illustrative transaction costs
Delaware transfer tax allocated to seller	−$8,000	Separate transaction tax; example only
REW-EST estimated income-tax payment	−$8,316	Based on illustrative gain calculation above
Illustrative seller cash	$219,684	Amount remaining after listed items

This table is not a quote or a prediction of actual Delaware closing costs. The point is to show that mortgage payoff, transfer tax, closing fees and REW-EST withholding are separate items.

A mortgage payoff does not reduce taxable gain merely because it reduces the check the seller receives. Debt and basis are different tax concepts.

Likewise, the withholding payment does not become larger or smaller merely because a buyer financed the purchase.

When a Principal Residence May Qualify for an Exemption

A former principal residence deserves careful review because Delaware’s REW-EST contains a box for situations in which gain realized from the sale will be excluded from income for the tax year of the sale or exchange.

For many individual homeowners, the relevant federal provision is Internal Revenue Code §121.

The IRS explains that a taxpayer may generally qualify for the main-home exclusion if the applicable ownership and use requirements are satisfied. Subject to the federal rules and limitations, qualifying taxpayers may exclude up to $250,000 of gain, or up to $500,000 for many qualifying joint filers.

But three cautions are essential.

First, simply calling a Delaware property “my old home” does not prove that the entire gain is excluded.

Second, rental use, depreciation, prior exclusions, periods of nonqualified use and other facts can affect the federal result.

Third, Delaware law requires exemption/exclusion declarations to be made under penalties of perjury. Section 1126 says that a claim relying on a capital-gain exemption or exclusion must include the facts and citation to the Internal Revenue Code provision relied upon.

A seller whose full gain is legitimately excluded may therefore have no REW-EST payment due under Part 5. A seller whose gain is only partly excluded should not assume the same zero-payment result; the remaining recognized gain needs to be handled correctly.

What Happens on a No-Gain Sale?

A seller who has no recognized gain may also have a zero estimated-payment result, but “I am receiving less cash than I paid for the house” is not itself a valid gain calculation.

The current REW-EST works from net sales price and adjusted basis.

A simplified basis framework might look like:

Original acquisition cost

• qualifying acquisition costs
• capital improvements
  − depreciation and other required reductions
  ± other tax-basis adjustments
  = adjusted basis

Compare that figure to the amount realized under the applicable tax rules.

The IRS similarly explains that gain generally depends on amount realized versus adjusted basis, rather than the amount of cash remaining after paying off a mortgage.

For example, assume:

• net sale price: $280,000;
• properly documented adjusted basis: $300,000.

There may be no positive gain to which the REW-EST percentage is applied. But whether a loss is deductible is a separate federal/state tax question; a personal-residence loss, for example, generally is not deductible federally.

Table 4: Situations That May Produce Zero or Reduced Settlement Payment

Situation	Potential treatment	Useful documentation
Seller is a Delaware resident	Nonresident withholding does not apply	Residency information
No positive gain under REW-EST computation	No gain-based estimated payment	Purchase and improvement records
Gain completely excluded under qualifying tax rule	Part 5 may produce no payment	Documentation supporting exclusion
Only part of gain is excluded	Tax may remain on recognized portion	Full gain/exclusion analysis
Qualifying foreclosure/deed-in-lieu	Statutory special treatment	Foreclosure documentation
Installment sale	Part 7 says no payment at that point under current form	Installment agreement and tax records
Qualified nonresident pass-through entity with approved REW-EXM	Entity-specific exemption from remittance	DOR approval

The separate REW-EXM form should not be confused with the individual homeowner’s principal-residence exclusion. REW-EXM is an application designed for qualifying nonresident pass-through entities and requires prior Division of Revenue approval.

How an Alternative Withholding Amount Works

Sellers sometimes ask whether they can simply tell the closing attorney, “My accountant estimates that I only owe $2,000, so withhold $2,000.”

That is not how the current form is structured.

The individual’s statutory options include the declaration based on estimated recognized gain, the Director’s alternative calculation using amount realized less recorded liens, and qualifying exemption/exclusion declarations. Current REW-EST implements the calculation and certification process.

Therefore, an “alternative amount” should mean a result produced under an authorized method—not a negotiated number selected to preserve cash at settlement.

Part 6 requires factual inputs for sales price, selling expenses and adjusted basis. Part 8 carries the calculated estimated income tax due forward as the amount paid. The seller signs the form under penalty of perjury.

If the gain computation is uncertain, resolve that uncertainty with supporting records or qualified advice instead of lowering the amount without authority.

Selling a Delaware House From Out of State for Cash

If you need to sell a Delaware house from out of state, an all-cash buyer may remove mortgage underwriting from the buyer’s side of the transaction. It does not remove Delaware’s recording or estimated-income-tax rules.

A cash buyer can potentially close faster because there is no buyer mortgage approval, lender appraisal or loan-clearance process. The site’s guide to the Delaware cash-home-sale process explains the broader transaction model.

For REW-EST purposes, however, the key event is still the Delaware real-property conveyance.

Whether the buyer:

• pays $300,000 from a bank account;
• uses conventional financing;
• is a local investor;
• closes in seven days;
• closes in fourteen days;
• buys the home as-is; or
• plans to renovate the property

does not by itself create an exemption from non-resident withholding.

Delaware requires the applicable REW-EST documentation and payment with the deed before recording.

Why Cash Buyers Still Need Settlement Tax Compliance

The absence of a lender changes financing logistics, not the seller’s state income-tax obligations.

In fact, a fast cash closing makes early tax preparation more important. In a longer financed transaction, the seller may have several weeks to search for a 15-year-old HUD-1, improvement invoices or rental depreciation schedules. A seven-day closing leaves much less room for that reconstruction.

Someone selling a vacant property quickly can also review how to sell a vacant or abandoned Delaware house for cash for the non-tax operational issues.

Before accepting an aggressive closing date, tell the attorney that you live outside Delaware and ask when REW-EST information is needed.

What Documents to Bring to Settlement

Not every item below is mandatory in every closing. Some establish identity or title; others help calculate REW-EST; still others become important only when the property was inherited, rented or previously used as a principal residence.

Table 5: Documents an Out-of-State Seller Should Gather

Document	Why it matters	Who may use it
Government-issued identification	Closing identity verification	Settlement attorney
SSN/EIN or other required taxpayer ID	REW-EST and tax-account matching	Settlement office/DOR
Current deed/title information	Confirms ownership	Closing attorney
Original purchase settlement statement	Supports acquisition cost and certain costs	Seller/tax preparer
Improvement invoices/receipts	May support basis additions	Tax preparer
Prior sale/purchase records	Helps reconstruct basis	Tax preparer
Depreciation schedules	Adjusts basis after rental/business use	Tax preparer
Date-of-death appraisal	May support inherited-property basis	Tax preparer
Estate/probate documents	Establish authority and inherited ownership	Attorney
Section 121/home-occupancy records	May support principal-residence exclusion	Tax preparer/attorney
Mortgage/lien information	Needed for payoffs and settlement	Closing attorney
Prior REW-EST/5403 correspondence	Useful when correcting prior tax-account issues	DOR/tax preparer

The current REW-EST specifically requires the seller’s name, SSN or EIN and post-settlement mailing address. If there are multiple sellers, the current instructions require REW-SCH rather than attempting to place all taxpayers under one identification number.

Keep a final copy of the completed REW-EST after settlement. The annual PIT-NON instructions specifically tell individual taxpayers claiming the payment to submit copies of the REW-EST forms.

Why Adjusted Basis Matters Before Closing

Adjusted basis is the number most likely to turn a superficially simple Form 5403 transaction into a documentation project.

The current REW-EST instructions say adjusted basis includes original purchase price, non-deductible closing costs and improvements, reduced by depreciation previously taken for tax purposes.

That definition makes several records particularly valuable.

A new roof, structural addition or qualifying major renovation may affect basis differently from routine maintenance. Depreciation claimed while a property was rented generally reduces basis even if the seller no longer thinks about the property as an investment.

Other transactions introduce specialized rules:

• gifts can involve carryover-basis concepts;
• inherited property generally uses death-related valuation rules;
• casualty adjustments can change basis;
• previous exchanges may produce carryover/deferred basis issues.

This article is not intended to calculate any of those outcomes. The point for settlement planning is narrower: basis should be reconstructed before REW-EST is finalized.

A seller should not substitute mortgage balance for adjusted basis. Nor should the seller automatically use the original purchase price if decades of capital improvements or depreciation have changed the tax basis.

Inherited and Rental Properties: Extra Documentation to Gather

Inherited Delaware Property

Inherited real estate deserves special attention because the heir’s basis often does not equal what the deceased owner originally paid.

Current IRS Publication 523 explains that, subject to the applicable rules, inherited property is generally based on the property’s fair market value at the decedent’s date of death or an applicable alternate valuation date.

An out-of-state heir should therefore look for:

• date-of-death appraisal;
• estate inventory;
• estate tax valuation if one was prepared;
• probate/accounting documents;
• records of improvements made after inheritance.

Someone preparing to sell inherited property in Delaware should get the basis documentation into the closing/tax workstream early.

Rental or Investment Property

Rental property adds another recurring issue: depreciation.

The REW-EST instructions expressly tell the seller to reduce adjusted basis by depreciation previously taken for tax purposes.

That means the purchase price plus renovation costs alone may not produce the correct basis.

The annual federal and Delaware return may involve additional rental-property tax rules, including character of gain and depreciation-related treatment. Those calculations go beyond the settlement form and should generally be handled by the seller’s tax professional.

For closing purposes, gather prior federal Schedule E records, fixed-asset or depreciation schedules and records covering property conversions between personal and rental use.

Form 5403 Withholding Is Not Your Final Delaware Tax

This concept is important enough to repeat: REW-EST withholding is an estimated payment.

Section 1126 says the remitted amount is credited to the nonresident transferor and expressly states that the withholding provision itself does not impose a tax or change the transferor’s underlying tax liability.

Your annual return determines the actual result.

Table 6: Withholding Versus Final Tax

Item	Illustrative amount	Result
REW-EST payment at closing	$12,000	Estimated payment/credit
Actual Delaware income-tax liability after return calculation	$8,500	Illustrative final liability
Excess payment	$3,500	Potential overpayment before other return adjustments
Potential refund attributable to difference	$3,500	Subject to complete return and any other balances/offsets

A different seller might have:

• $8,000 paid at settlement;
• $10,000 final liability;
• $2,000 still due.

And another might have withholding almost exactly equal the final liability.

That is why sellers should not advertise, budget or negotiate a property sale on the assumption that “Delaware takes 6.6% of my gain permanently.” The settlement payment and final annual income tax are separate stages.

How to Recover Over-Withheld Money

The 5403 refund estimated tax process is essentially an annual-return reconciliation for an individual seller.

For tax year 2025, Delaware’s current individual non-resident form is PIT-NON – Delaware Individual Non-Resident Income Tax Return. Delaware says gains or losses from real property located in Delaware belong in the Delaware-source column of that return.

The 2025 procedure provides a particularly clear illustration:

1. Report the Delaware-source real-estate transaction on PIT-NON as required.
2. Calculate actual Delaware tax.
3. Enter REW-EST real-estate capital-gains payments on Line 53.
4. Attach copies of the REW-EST forms.
5. Add the payment to the return’s refundable credits.
6. If total refundable credits exceed the calculated tax, the return produces an overpayment.
7. After applicable contributions, carryovers, penalties or other adjustments, the return calculates the net refund.

A seller relying on the principal-residence exclusion should review the IRS home-sale exclusion guidance carefully. The federal rules include ownership and use tests, and merely having lived in the Delaware property at some point does not automatically make the full gain excludable. 

The Division specifically warns taxpayers not to put REW-EST payments on the ordinary withholding line. For the 2025 PIT-NON, they belong on Line 53 rather than Line 49.

The precise line number may change in future tax years, so sellers should always use the return for the year in which the property was sold.

Can the Seller Get a Refund Before Filing the Annual Return?

The current official individual materials reviewed for this article describe claiming REW-EST payments through the non-resident annual return and calculating the resulting overpayment/refund there. 

I did not find a current Delaware individual Form 5403/REW-EST early-refund procedure that lets an ordinary seller automatically obtain excess settlement withholding immediately after closing.

Accordingly, sellers should plan on annual-return reconciliation unless the Delaware Division of Revenue confirms another procedure for their specific circumstances.

If the payment was plainly posted under a wrong taxpayer ID, duplicated or resulted from an administrative closing error, that is different from simply deciding after closing that the gain estimate was too high. Contact the Division or a qualified preparer rather than attempting to amend the closing paperwork informally.

Delaware does provide online tax filing and refund tools through the Taxpayer Portal.

No reliable universal refund-processing time should be assumed.

When the Seller Owes More Than Was Withheld

REW-EST is not a liability cap.

Final tax can exceed the settlement payment when, for example:

• the estimated gain was understated;
• basis was later corrected downward;
• depreciation was omitted from the closing estimate;
• an anticipated exclusion does not fully apply; or
• other Delaware-return calculations change the final liability.

The PIT-NON reconciliation handles that possibility too: when final tax exceeds payments and refundable credits, the return produces a balance due.

Form 5403 vs. Delaware Transfer Tax and Federal Capital Gains Tax

Several different taxes can be connected to the same Delaware property sale. They should not be merged into one concept.

Table 7: Which Tax Is Which?

Tax/rule	Applies to	Collected at Delaware closing?	Final tax or prepayment?
REW-EST/Form 5403 estimated payment	Applicable nonresident Delaware real-estate sellers	Yes, when payment is due	Prepayment/estimated tax
Delaware income tax	Delaware-source taxable income/gain	Final amount calculated on return	Final state tax liability
Delaware realty transfer tax	Taxable real-property transfer	Generally handled as part of closing/recording	Transaction tax
Federal capital-gains income tax	Federal taxable gain	Usually reconciled under federal income-tax system	Federal tax liability
FIRPTA	Certain dispositions by foreign persons	Can involve federal withholding	Federal foreign-person withholding regime

Delaware Form 5403/REW-EST is not FIRPTA.

A Delaware “nonresident” might simply be a U.S. citizen living in Pennsylvania. FIRPTA concerns whether the seller is a foreign person for U.S. federal tax purposes. The two definitions answer completely different questions.

Nor is REW-EST the Delaware realty transfer tax. Delaware lists REW-EST and RTT-TAX as separate forms under its Realty Transfer section.

A seller can therefore see both charges associated with one closing.

For owners with title complications, how liens and judgments affect Delaware cash sales covers another separate category of settlement deductions.

Common Form 5403 Mistakes

Small assumptions made before closing can produce large differences in seller proceeds.

Table 8: Common Seller Mistakes

Mistake	Why it matters	Better approach
Assuming “I moved away, so the form does not apply”	Moving can instead create nonresident status	Establish tax residency before closing
Thinking REW-EST is Delaware transfer tax	They are separate systems	Review each settlement deduction separately
Waiting until settlement day to establish basis	Missing Part 6 information can affect withholding	Reconstruct basis before the final statement
Forgetting capital improvements	May understate basis	Gather invoices and closing records
Ignoring depreciation from rental years	Can overstate basis	Obtain depreciation schedules
Assuming cash buyer means no withholding	Buyer financing is irrelevant to the tax rule	Treat tax compliance as part of recording
Claiming a principal-residence exemption automatically	§121 has eligibility and limitation rules	Verify actual exclusion
Treating mortgage payoff as basis	Debt payoff and tax basis are different	Use tax-basis records
Signing an exemption without supporting facts	REW-EST is signed under penalty of perjury	Review certification before signing
Losing the REW-EST after closing	PIT-NON instructions request copies	Keep final form with tax records
Reporting REW-EST as ordinary wage withholding	Current PIT-NON uses a separate credit line	Follow current return instructions
Believing withholding is final tax	Could lose a refund or create unpaid balance	File and reconcile the annual return
Using gross sale price as “gain”	Gain accounts for sales adjustments and basis	Complete the prescribed calculation

What Happens if Form 5403 Is Completed Incorrectly?

Errors can show up in several ways.

An overstated gain can result in more money leaving settlement than necessary, forcing the seller to recover the overpayment later.

An understated gain may leave additional Delaware tax due on the annual return.

An incorrect SSN or EIN can interfere with the Division’s ability to match the settlement payment to the eventual return. Current REW-EST instructions specifically require one taxpayer ID per return and REW-SCH when multiple sellers or qualifying pass-through owners are involved.

Incorrect residency or exemption certification can be more serious because the form is signed under penalty of perjury.

And because the form/payment must accompany the deed before recording, unresolved REW-EST problems can become a closing or recording problem rather than merely an accounting problem after the fact.

Practical Pre-Closing Form 5403 Workflow

For an out-of-state owner, the following sequence keeps the tax work aligned with the closing rather than treating it as a last-minute deduction.

1. Confirm your residency status: Determine whether you are a Delaware resident, full-year nonresident or part-year resident for the relevant year.
2. Tell the settlement attorney where you live: Do this as soon as the closing file opens.
3. Use the current REW-EST materials: Do not rely on an old Form 5403 PDF merely because that is the familiar form number.
4. Determine whether payment is required: Review resident status, gain recognition, exclusions, foreclosure rules and other applicable provisions.
5. Identify the ownership type: An individual, partnership, LLC, S corporation, C corporation, estate and trust can require different tax analysis.
6. Gather the original acquisition statement.
7. Gather capital-improvement records.
8. Gather rental depreciation schedules where applicable.
9. Establish an estimated adjusted basis.
10. Calculate estimated recognized gain using the current form.
11. Have any principal-residence exclusion reviewed before claiming it.
12. Review the draft REW-EST before settlement.
13. Compare REW-EST to the settlement statement. Make sure the tax debit corresponds with the amount you expect.
14. Retain the signed REW-EST and proof of the closing disbursement.
15. After year-end, file the appropriate Delaware return and claim the payment credit.

That sequence is especially helpful in a seven- or fourteen-day transaction, when the property may be ready to close long before the seller’s tax records are organized.

Delaware Form 5403 Seller Checklist

Before signing final closing documents:

• Confirm whether you are a Delaware resident, nonresident or part-year resident for tax purposes.
• Tell the settlement attorney that your current residence is outside Delaware.
• Obtain the current REW-EST form and instructions.
• Verify whether an estimated payment actually applies.
• Identify the correct seller/entity classification.
• Review any legitimate gain-exclusion or nonrecognition provision.
• Gather the original purchase closing statement.
• Gather qualifying capital-improvement documentation.
• Obtain depreciation records if the property was rented.
• Gather inheritance valuation records if applicable.
• Estimate adjusted basis.
• Review selling expenses used in Part 6.
• Review the proposed gain calculation before closing.
• Confirm the REW-EST amount on the final settlement statement.
• Confirm that the correct SSN/EIN is used.
• Complete REW-SCH when currently required for multiple sellers/entity members.
• Keep a copy of the signed REW-EST.
• Keep the settlement statement with your tax file.
• File the applicable Delaware non-resident return after year-end.
• Claim the real-estate estimated-tax payment on the correct return line.
• Reconcile any refund or additional balance through the return.

Pro Tip: Send the closing package to your tax preparer shortly after settlement instead of waiting until tax season. That makes it easier to resolve a missing form or taxpayer-ID mismatch while the closing file is still readily accessible.

Frequently Asked Questions

What is Delaware Form 5403?

Form 5403 was Delaware’s former name/number for the Real Estate Tax Return – Declaration of Estimated Income Tax. The current form is REW-EST. Delaware tax-modernization materials expressly identify REW-EST as the successor to Form 5403.

Does Delaware withhold tax when a non-resident sells real estate?

Applicable nonresident sellers must make an estimated Delaware income-tax payment with the deed unless an applicable exclusion or other treatment produces no payment. The payment is withheld from available net proceeds.

Who counts as a non-resident seller in Delaware?

For §1126, a nonresident individual is someone who is not a resident individual of Delaware for the individual’s entire tax year. Part-year situations require additional analysis.

How much does Delaware withhold at closing?

The current REW-EST instructions apply 6.6% to estimated gain for taxpayers other than C corporations and 8.7% for C corporations. The actual dollar amount therefore depends on the calculation rather than simply the home’s sale price.

Is Form 5403 withholding based on the sale price or gain?

When Part 6 is properly completed, the current form calculates net sales price, subtracts adjusted basis and applies the applicable rate to resulting gain. Delaware law also authorizes an alternative proceeds/liens calculation, and the current form warns that incomplete Part 6 information can result in withholding from net proceeds.

Who completes and files Form 5403/REW-EST?

The seller supplies and certifies the information and signs REW-EST. Operationally, the settlement professional normally incorporates it into the closing/recording package. The form and payment accompany the deed to the Recorder before recording.

Does a principal residence qualify for an exemption?

A gain that is properly excluded from income may qualify for Part 5 treatment, including qualifying federal home-sale exclusion circumstances. But merely having lived in the home does not establish a complete exclusion.

What if I sell the property at no gain?

If the properly calculated transaction produces no positive gain, the gain-based estimated-payment calculation may produce no tax payment. The seller needs a defensible basis rather than simply comparing purchase price with cash received.

Can I declare a lower estimated withholding amount?

There is no general current-form option allowing a seller to select any lower amount desired. A different amount should result from an authorized gain calculation, statutory alternative, exemption, exclusion or other recognized treatment.

Does an all-cash sale avoid Form 5403 withholding?

No. Removing buyer mortgage financing does not remove Delaware’s nonresident real-estate withholding and recording requirements.

Where does Form 5403 appear on my settlement statement?

The estimated payment normally reduces seller proceeds as a tax-related debit or disbursement. The exact label depends on the settlement document format.

Is the withholding my final Delaware tax bill?

No. Delaware law expressly treats the payment as a credit and says the withholding provision itself does not impose or determine the transferor’s final tax liability.

How do I recover over-withheld money?

An individual generally reports the transaction on the Delaware PIT-NON return and claims REW-EST payments as real-estate capital-gains tax payments. If total payments exceed final liability, the return can produce an overpayment and refund.

Do I have to file a Delaware non-resident return after the sale?

A nonresident with reportable Delaware-source gain generally must address that Delaware-source income on the applicable nonresident return. Current PIT-NON instructions specifically require gains or losses from Delaware real property to be reported in the Delaware-source column.

Is Form 5403 the same as Delaware transfer tax?

No. REW-EST is an estimated income-tax collection mechanism. Delaware realty transfer tax is a separate transaction tax with separate forms and rules.

Conclusion

For an owner selling Delaware property from out of state, the biggest Form 5403 lesson is that the form’s modern name is REW-EST and the settlement payment is an estimated Delaware income-tax payment—not automatically the seller’s final tax bill.

For most non-C-corporate taxpayers, the current gain-based REW-EST calculation uses Delaware’s 6.6% rate after net sales price and adjusted basis are determined. 

Legitimate exclusions, no-gain transactions, installment treatment and other statutory circumstances can change what is due, so sellers should not assume that every out-of-state owner loses the same percentage of the sale price.

A cash buyer or quick closing does not bypass the process. It simply makes early preparation more important.

The strongest practical protection is documentation: establish residency, collect purchase and improvement records, retrieve depreciation information where relevant, review the REW-EST before settlement, and retain the final signed form.

After the sale year ends, an individual nonresident reconciles the payment on the applicable Delaware PIT-NON return. If the closing payment exceeded actual Delaware liability, the resulting overpayment can be recovered through that return process; if the payment was insufficient, the return determines the remaining balance.
