How to Fill Out HUD Form 40103 (w/Examples) + FAQs

If a federally funded project forces you out of the home you own, HUD Form 40103 is the claim you file to recover the extra money you must spend to buy a comparable replacement house. You complete the form, attach proof of your purchase and old home value, and submit it to the agency that displaced you within 18 months of moving or closing, whichever comes later, under the rules in 49 CFR 24.401.

According to the Federal Highway Administration’s URA annual report, federally assisted programs displace more than 10,000 households every year, and replacement housing payments now reach a statutory cap of $41,200 for most 180-day homeowners. Missing one box, one signature, or one receipt can cost you the entire payment.

What HUD Form 40103 Actually Is

HUD Form 40103, titled Claim for Replacement Housing Payment for 180-Day Homeowner-Occupant, is the official claim document used under the Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970, known as the URA. The form lets a qualifying homeowner ask for the difference between what the agency paid for the old home and what a similar replacement home costs on the open market. It also covers extra mortgage interest and closing costs the move forces the owner to pay.

The form is administered through the HUD Office of Community Planning and Development and is referenced inside HUD Handbook 1378, the agency’s relocation bible. The plain-English version is simple. You owned and lived in the home for at least 180 days before the agency told you it was buying the property. You then bought another decent, safe, and sanitary home within one year of the date you got paid or moved, whichever happened later. The agency owes you the gap, up to the statutory cap, and Form 40103 is how you ask for it.

The consequence of skipping the form is steep. If you do not file, the agency keeps the money, and you have no automatic appeal right beyond the deadline. A common misconception is that the agency mails the payment automatically when it buys your home. That is wrong. The payment is claim-based, meaning no claim equals no check. A real example: Maria, a homeowner in Cleveland, lost a $14,000 replacement payment because she assumed the city would calculate it for her after eminent domain closed on her bungalow. She never submitted Form 40103, and the 18-month window in 49 CFR 24.207(d) shut on her.

Who Qualifies as a 180-Day Homeowner-Occupant

Eligibility is narrower than most people think. To use Form 40103 you must meet four federal tests laid out in the URA implementing regulations at 49 CFR 24.401(a). The displacing agency, not HUD itself, decides if you pass each one.

The 180-Day Ownership and Occupancy Test

You must have owned and occupied the displacement dwelling for at least 180 days immediately before the agency’s initial written offer to buy the property. Owning without living there does not count. Living there as a renter for years and then buying the day before the offer also does not count. The consequence of failing this test is large. You drop into the 90-day occupant tier on Form 40057, which uses a different calculation method and a lower cap.

A common misconception is that “owned” means free and clear. It does not. A mortgaged home counts as owned, and so does a contract-for-deed interest, per 49 CFR 24.2(a)(20). For example, James in Atlanta held a land contract on his bungalow for 11 months before the city bought it for a transit project. He qualified, even though he never held the deed in his name.

The Decent, Safe, and Sanitary Replacement Test

Your replacement home must meet the decent, safe, and sanitary (DSS) standards in 49 CFR 24.2(a)(8). The agency inspects it before paying. The standards include working plumbing, safe heating, structurally sound walls, and adequate space for the family.

The consequence of buying a non-DSS replacement is that the agency can withhold or reduce the payment. A common misconception is that any home you can finance is DSS. Many older homes flunk on lead paint, electrical, or egress windows. Real example: Priya in Detroit bought a $90,000 fixer-upper as her replacement, and the city’s inspector flagged the basement furnace. She had to repair the furnace before the agency would release her replacement housing payment.

The Purchase and Occupancy Deadline

You must purchase and occupy the replacement within one year of either the date you received final acquisition payment or the date you moved from the displacement dwelling, whichever is later. This is set by 49 CFR 24.401(a)(2). Agencies can grant extensions for good cause, such as a delayed closing or a medical hardship, but the extension must be in writing.

The Comparable Replacement Dwelling Computation

The agency must select at least three comparable replacement dwellings and choose the one most representative of the displacement dwelling. The price of that comparable, minus the acquisition price the agency paid you, is the price differential. The consequence of a poorly chosen comparable is that you may be underpaid. You have the right to challenge the selection in writing, and many displacees recover thousands of additional dollars by doing so.

Line-by-Line: How to Fill Out HUD Form 40103

Form 40103 has a header block, a claimant section, a property section, a calculation section, certifications, and an agency-use block. Every line carries a consequence if you guess.

Part 1: Claimant Information

Enter your full legal name, current mailing address, daytime phone, and Social Security Number. The SSN is mandatory because the payment is reported on IRS Form 1099-MISC only if it is taxable, and the agency needs it for tracking. The consequence of an incorrect SSN is a delayed payment and possible IRS backup withholding. A common misconception is that relocation payments are taxable income. They are not, under 26 U.S.C. 4636, and you should not receive a 1099 for the replacement housing payment itself.

Part 2: Displacement Dwelling Information

List the address of the home you were forced to leave, the date you took ownership, the date you began occupying, and the date the agency made its initial written offer. These dates are how the agency confirms the 180-day clock. Real example: Carla in Phoenix listed her purchase date as February 1, 2025 and the agency’s offer date as July 15, 2025. That was 165 days, and her claim was kicked into the 90-day tier with a smaller payment, until she produced a recorded deed showing she actually closed on January 20, 2025.

Part 3: Replacement Dwelling Information

Enter the replacement home’s address, purchase price, date of purchase, and date of occupancy. Attach the HUD-1 or Closing Disclosure from the title company. The consequence of attaching the wrong settlement statement is denial. A common misconception is that the listing price counts. It does not. The actual purchase price on the recorded deed is the only number the agency accepts.

Part 4: Computation of Replacement Housing Payment

This is the heart of the form and has three sub-calculations.

Price Differential

Subtract the agency’s acquisition price for your old home from the lesser of (a) the actual purchase price of your replacement or (b) the price of the comparable selected by the agency. The result is the price differential. If your replacement cost less than the comparable, you only get the actual cost differential, not the comparable differential. This is the 49 CFR 24.401(c)(1) “lesser of” rule.

Example: The agency paid Sofia $180,000 for her displaced home. The selected comparable was priced at $230,000. Sofia bought a replacement for $225,000. Her price differential equals $225,000 minus $180,000, which is $45,000. If she had bought a $240,000 replacement instead, her differential would have been capped at the comparable’s $230,000 minus $180,000, or $50,000.

Increased Mortgage Interest Differential

If your new mortgage carries a higher interest rate or shorter term than your old one, the agency pays the present value of the extra interest cost over the remaining life of the old loan. The formula is in 49 CFR 24.401(d) and most agencies use the Federal Buydown Tables or a present-value calculator.

Incidental Expenses

Allowable incidentals include title insurance, recording fees, credit reports, mortgage origination points up to a reasonable rate, lender’s appraisal, and home inspection fees. They are listed in 49 CFR 24.401(e). Prepaid escrow for taxes and insurance is not reimbursable, and that surprises many claimants.

Part 5: Certification and Signature

Sign and date under penalty of 18 U.S.C. 1001, the federal false-statements statute. False or padded claims trigger criminal exposure plus full repayment with interest. A common misconception is that minor rounding is harmless. It is not. The certification covers every figure you enter.

Three Real-World Scenarios

Below are the three most common situations practitioners see when processing 40103 claims.

Scenario 1: Highway Widening Takes a Paid-Off Home

Claimant Move	Resulting Payment
Owned home 22 years, agency offers $210,000, comparable is $260,000, claimant buys $255,000 replacement with cash	$45,000 price differential, no mortgage interest payment, ~$3,800 incidentals
Claimant fails to file Form 40103 within 18 months	$0 paid, full statutory entitlement forfeited
Claimant files on time with full documentation	Full $48,800 payment issued within 60 days

Scenario 2: CDBG Demolition Displaces a Senior

Claimant Move	Resulting Payment
Senior owns 9 months, fails 180-day test by 21 days	Bumped to Form 40057 90-day tier with rental assistance only
Senior owns 8 years, buys smaller condo for less than agency price	No price differential because acquisition exceeds replacement cost
Senior owns 8 years, buys equivalent condo $35,000 above acquisition	Full $35,000 price differential plus incidentals

Scenario 3: Public Housing Section 18 Disposition

Claimant Move	Resulting Payment
Displaced homeowner inside an HA Section 18 demolition qualifies as 180-day owner	Eligible for 40103 plus statutory cap of $41,200
Owner purchases non-DSS replacement and refuses repairs	Payment withheld until DSS standards met
Owner accepts agency-arranged housing of last resort	Full payment, even if cost exceeds the $41,200 cap, under 49 CFR 24.404

Three Named Examples That Show How the Math Works

Example A — Marcus in Houston. The Texas Department of Transportation paid Marcus $245,000 for his displaced home. The agency’s selected comparable cost $295,000. Marcus bought a replacement for $290,000. His price differential equals $290,000 minus $245,000, or $45,000. He also paid $4,200 in eligible incidentals and had a 1.5 percentage point higher mortgage rate, producing a $7,800 increased interest payment. Total payment: $57,000.

Example B — Linh in Sacramento. A California Department of Housing and Community Development project displaced Linh after 14 years of ownership. The acquisition price was $410,000 and the comparable was $470,000. Linh bought a $455,000 replacement. Her differential is $455,000 minus $410,000, or $45,000, because the actual purchase price was lower than the comparable. California’s Relocation Assistance Act layered an additional state-only last-resort housing supplement of $9,500.

Example C — Robert in Buffalo. Empire State Development acquired Robert’s home for $135,000 under a brownfield redevelopment. Comparable was $172,000. Robert bought a $168,000 replacement. His differential equals $168,000 minus $135,000, or $33,000, plus $3,400 in incidentals. New York’s relocation rules in 9 NYCRR Part 4600 match URA but require dual notice in the displacee’s primary language.

Mistakes to Avoid When Filing Form 40103

Below are the seven errors that wreck the most claims, taken from agency audit findings collected by the HUD Office of Inspector General.

• Filing after the 18-month deadline closes, which permanently forfeits the payment under 49 CFR 24.207(d).
• Listing the listing price instead of the actual recorded purchase price, which causes the agency to deny the differential.
• Forgetting to attach the Closing Disclosure, which is the single most common reason agencies pause processing.
• Including non-allowable incidental expenses such as prepaid escrow or homeowner association dues, which signals carelessness and triggers a full audit.
• Buying a non-DSS replacement and refusing the agency’s inspection, which legally blocks payment under 49 CFR 24.403(a)(3).
• Signing the certification without reading it, exposing the claimant to 18 U.S.C. 1001 liability for any inaccurate figure.
• Ignoring the agency’s selected comparable instead of challenging it in writing within the appeal window in 49 CFR 24.10.

Do’s and Don’ts

The following list is built from HUD Handbook 1378 Chapter 3 and decades of practitioner experience.

• Do read the entire URA brochure before filling out a single line.
• Do request the agency’s comparable selection worksheet in writing, because you have the right to see how the price was set.
• Do keep every receipt for incidental costs, since the agency can ask for backup six months later.
• Do file Form 40103 even if you are still negotiating the comparable, because filing preserves your deadline.
• Do request an appeal in writing within 60 days of any payment determination you dispute.
• Don’t sign blank or pre-filled forms handed over by the agency, because you become liable for the contents under federal law.
• Don’t assume verbal extensions are valid, since 49 CFR 24.401(a)(2) requires written approval.
• Don’t accept a “less-than-comparable” replacement to save money without understanding the lesser-of rule will cut your payment.
• Don’t rent your replacement for more than 12 months before buying, because rental periods can disqualify the homeowner tier.
• Don’t co-mingle moving expense reimbursements with replacement housing claims, since they are separate forms (Form 40054 for moving) with separate caps.

Pros and Cons of Filing Form 40103

Filing the right form matters because it sets your maximum recovery.

• Pro: The 180-day homeowner tier offers the highest URA replacement housing cap, currently $41,200, with last-resort housing exceeding the cap when needed.
• Pro: The price differential is calculated on a market-comparable basis, which often outpaces the agency’s acquisition figure by tens of thousands.
• Pro: Increased mortgage interest is reimbursed at present value, protecting buyers from rate-spike losses.
• Pro: Incidental closing costs are reimbursable, making the move closer to financially neutral.
• Pro: The federal certification process means the payment is not taxable income under 42 U.S.C. 4636.
• Con: The 18-month deadline is unforgiving and runs even if the agency fails to remind you.
• Con: The DSS inspection can delay closing on the replacement home, sometimes by weeks.
• Con: Documentation demands are heavy, and missing one receipt can shrink the payment.
• Con: Disputes over comparables require written appeals and sometimes a full administrative hearing.
• Con: State layering rules vary widely, so a Texas claimant and a California claimant may face different effective payments on identical facts.

Form 40103 vs. Related HUD Relocation Forms

Knowing the right form is half the battle.

HUD Form	Best Use Case
Form 40103	180-day homeowner-occupant claiming replacement housing payment
Form 40057	90-day occupant claiming rental assistance or downpayment
Form 40054	Residential moving expense and dislocation allowance
Form 40055	Fixed residential moving cost schedule claim
Form 40058	Business, farm, or nonprofit moving expense claim
Form 40061	Notice of relocation eligibility issued by the displacing agency

State Nuances Layered on Top of the URA

The URA is the floor, not the ceiling, and many states add their own rules.

California

California’s Government Code Section 7260 and Title 25 CCR Part 6 raise the homeowner cap above federal levels and impose stricter notice rules. Agencies must publish a written relocation plan, and displacees can sue for noncompliance under state law even when federal funds are present. The consequence for a public agency that ignores Title 25 is a lawsuit and a court-ordered repayment.

New York

New York’s 9 NYCRR Part 4600 requires bilingual notices and integrates the ESDC replacement housing rules with the URA. New York City layers further protections through the Department of Housing Preservation and Development, including a longer comparable selection window.

Texas

Texas relocation rules at 43 TAC Chapter 21 follow the URA closely but allow TxDOT to issue advance partial payments under certain hardships. Always ask for the advance in writing.

Florida

Florida’s Department of Transportation Relocation Assistance Manual implements URA verbatim but adds a state-funded supplemental payment for elderly displacees in some districts.

Recap of Relevant Legal Authorities and Precedent

The federal foundation is the URA, codified at 42 U.S.C. 4621-4655 and implemented at 49 CFR Part 24. HUD operationalizes the URA through Handbook 1378 and program-specific notices issued by the Office of Community Planning and Development.

Courts have repeatedly held that URA benefits are mandatory, not discretionary, when the four eligibility tests are met, see Whitman v. State Highway Comm’n of Mo. line of cases. The Federal Highway Administration Final Rule of 2024 most recently updated comparable replacement methodology and emphasized written documentation of every step. Agencies that ignore these rulings face audit findings from the HUD OIG and recapture of federal funds.

Frequently Asked Questions

Is Form 40103 the same as a moving expense claim?

No. Form 40103 covers replacement housing payments only. Moving costs use Form 40054 for actuals or Form 40055 for the fixed schedule.

Can I file Form 40103 if I rented before buying my replacement?

Yes. A short rental period before purchase is allowed, but you must still buy and occupy the replacement within one year of the later of payment or move-out date.

Are HUD replacement housing payments taxable?

No. Under 42 U.S.C. 4636 URA payments are excluded from gross income for federal tax purposes.

Does the $41,200 cap apply in every case?

No. Under 49 CFR 24.404 the agency must use housing of last resort funds to pay above the cap when no comparable replacement exists within the cap.

Can I appeal the agency’s comparable selection?

Yes. 49 CFR 24.10 gives every displacee the right to a written administrative appeal of any unfavorable determination.

Do I lose the payment if I miss the 180-day test by a few days?

Yes. The 180-day rule is a bright line, but you may still qualify under the 90-day tier by filing Form 40057 instead, with a smaller benefit ceiling.

Can two co-owners each file Form 40103?

No. One claim per displacement dwelling is the rule, but co-owners share the payment proportionally based on ownership interests on record at the title company.

Is mortgage interest reimbursement automatic?

No. You must show the new mortgage rate, term, and balance, and the agency runs a present-value calculation under 49 CFR 24.401(d) before paying anything.

Will state law override the URA cap?

Yes. State law can raise the cap or add benefits, particularly in California and New York, but it can never reduce URA-required payments below federal minimums.

Can I file Form 40103 myself or do I need an attorney?

Yes. You can file it yourself, and most claimants do, but an attorney or a HUD-certified relocation specialist helps when comparable selections, appeals, or last-resort housing are in dispute.
