For U.S. federal income tax, an inherited house generally starts with a basis equal to its fair market value (FMV) on the date the decedent died—not what the decedent originally paid. To calculate gain, subtract the home’s adjusted basis from the amount realized after eligible selling expenses. Improvements, depreciation, ownership structure, and eligibility for the home-sale exclusion can change the result, so the estate’s valuation records are essential.
This guide covers general federal rules. State tax and property-law consequences vary, and unusual estate, trust, or ownership facts can change the calculation. The IRS’s Publication 530 summarizes the general inherited-home basis rule.

Basis is the tax value used to calculate gain or loss when property is sold. For inherited property, the general starting point is the home’s FMV at the decedent’s date of death. It is commonly called a stepped-up basis when the home appreciated during the decedent’s ownership, but the adjustment can also be downward if the home’s value had fallen.
The IRS states that basis is generally the FMV on the date of death, or on the estate’s applicable alternate valuation date if the personal representative makes a valid election. An heir does not choose an alternate date independently. Ask the executor which valuation was used and request the supporting estate records. See IRS Publication 530 and Publication 551.

Do not automatically use the decedent’s original purchase price, the amount of the mortgage, or a current estimate of the home’s value. The relevant figure is the supported estate value under the applicable rules. If an estate-tax return was filed, the estate-tax value may control; a beneficiary who receives Schedule A to Form 8971 may also be subject to consistent-basis requirements. Ask the executor for the final value and any forms that apply.
What if no estate-tax return was filed?
IRS homeowner guidance says that if Form 706 was not filed, the home’s basis is its appraised value on the decedent’s date of death for state inheritance or transmission-tax purposes. The IRS also advises asking the executor about the date-of-death FMV. If no reliable appraisal or estate valuation is available, obtain professional advice about establishing a defensible value for the relevant date; a present-day estimate alone does not establish historical FMV.

The date-of-death value is the usual starting point. An alternate valuation date can apply only when the estate’s personal representative elects it under the estate-tax rules. Because the election and its consequences belong to the estate, do not substitute a later appraisal date simply because it seems more favorable. Confirm the value actually used in the estate records before calculating gain.
How do you calculate capital gain on an inherited house?
Use the same basic sale calculation as for other property: subtract adjusted basis from the amount realized. For this purpose, amount realized generally means sale consideration less eligible selling expenses; it is not simply the cash left after paying the mortgage.
- Find the sale consideration. Start with the sale price and review the closing statement and any Form 1099-S. Include other consideration when required.
- Subtract eligible selling expenses. The IRS worksheet includes costs directly connected with selling, such as commissions, advertising, legal fees, specified mortgage points or loan charges, and other qualifying sale costs.
- Establish the inherited starting basis. Use the applicable estate valuation, subject to ownership and other exceptions discussed below.
- Add qualifying capital improvements. Include eligible improvements made after inheritance that remained part of the property at sale.
- Subtract basis reductions. Account for depreciation allowed or allowable for rental or business use, casualty-loss deductions, certain insurance reimbursements, and applicable energy credits or subsidies tied to costs included in basis.
- Calculate adjusted basis. Start with inherited basis, add eligible increases, and subtract basis reductions.
- Subtract adjusted basis from amount realized. A positive result is gain; a negative result is loss. Whether any gain is taxable, or a loss is deductible, is a separate question.
This follows the framework in the IRS Publication 523 home-sale worksheet. The worksheet is a useful organizing tool even though an inherited home does not have an ordinary purchase-price basis.

Worked example
Suppose the estate records support an inherited basis of $400,000. After inheriting the house, the heir makes $20,000 of qualifying improvements, has $5,000 of allowable rental depreciation, sells for $450,000, and pays $25,000 in eligible selling expenses.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Adjusted basis: $400,000 + $20,000 − $5,000 = $415,000
- Amount realized: $450,000 − $25,000 = $425,000
- Arithmetic gain: $425,000 − $415,000 = $10,000
This illustration shows the arithmetic only. It is not an IRS statistic or an individual tax determination. The taxable result can depend on the sale allocation, depreciation rules, exclusion eligibility, and other facts.
Does the mortgage payoff reduce capital gain?
Usually, not as a separate deduction in the gain formula. The capital-gain calculation compares amount realized with adjusted basis; paying off the mortgage affects the seller’s net cash proceeds, not the home’s basis or the general formula. Use the closing statement to identify sale consideration and qualifying selling costs rather than subtracting the loan balance as though it were a selling expense.
Which home improvements increase basis?
Qualifying improvements generally add to basis when they add value, prolong the property’s useful life, or adapt it to a new use. Examples in Publication 523 include additions, decks, garages, new roofs, heating systems, and kitchen modernization.
Routine repairs and maintenance—work that keeps the home in ordinarily efficient operating condition—generally do not increase basis. A repair may be part of a larger qualifying remodeling or restoration project, however, so classify costs based on the project and records rather than assuming every invoice is either an improvement or a repair.

Keep receipts and, where practical, contracts, permits, and records that show the work was completed and remained part of the home when it was sold. Improvements made by the decedent may already be reflected in the estate-date FMV; do not add them again automatically. The basis addition is for eligible post-valuation costs, not an extra credit for a feature already captured in the valuation.
What can change the usual inherited-home basis?
The date-of-death FMV rule is a general rule, not a universal result. How the home was owned, the estate’s valuation choices, and unusual transfers can alter the basis calculation.
Surviving spouse and jointly owned property
For a jointly owned home, the decedent’s interest generally receives the applicable date-of-death or alternate-date FMV basis, while the surviving spouse’s pre-existing interest generally keeps its basis. In a straightforward half-and-half case, the total basis combines the survivor’s basis in their half with the FMV of the inherited half. The actual result depends on title, contributions, and applicable state law; do not assume every joint ownership arrangement is exactly 50/50.
Community property
For community property, the IRS says the basis of the entire property generally becomes its total FMV when one spouse dies—including the surviving spouse’s share—if at least half the value of the community-property interest is includible in the decedent’s gross estate. Whether property qualifies as community property and whether the condition is met depend on the facts and jurisdiction. See Publication 551.
Property given to the decedent shortly before death
A special rule may prevent the usual FMV basis if the heir, or the heir’s spouse, gave appreciated property to the decedent within the one-year period ending at death and the statutory conditions are met. In that situation, the decedent’s adjusted basis may carry over. Because this exception is fact-specific, disclose any such transfer to a tax professional rather than assuming a step-up applies.

Special-use valuation, trusts, and other estate facts
Real property used in farming or a closely held business can be subject to special-use valuation. Trust ownership, the form of title, estate elections, and other unusual facts—including certain historical elections involving 2010 decedents—can also affect the answer. If the property passed through a trust or was used in a business, confirm which valuation and basis rules apply before reporting a sale.
Is gain on an inherited house automatically long-term?
Generally, yes, if the inherited property is a capital asset: the IRS treats gain or loss as long-term regardless of how long the heir held the property. That classification does not by itself make a gain tax-free. The amount of gain, applicable tax treatment, and potential exclusion still depend on the facts. See Publication 550.
Can you use the home-sale exclusion?
Possibly, but inheriting a home alone does not qualify an heir for the federal home-sale exclusion. Under the general rule in Publication 523, a taxpayer must meet ownership and use tests—generally owning and using the home as a main home for at least two years during the five years before the sale—as well as the applicable prior-sale and other conditions.
Publication 523 describes a maximum exclusion of up to $250,000 for an eligible individual or up to $500,000 for a qualifying married couple filing jointly. These are rule-specific limits; confirm the publication and law applicable to the tax year of sale. Whether an heir may count any of the decedent’s ownership or use period depends on the particular test and facts. Do not assume the decedent’s residence history automatically satisfies the heir’s requirements.
Rental or business use can complicate eligibility and may produce taxable gain related to depreciation. Depreciation allowed or allowable can reduce basis even if it was not actually claimed, and depreciation-related gain may not qualify for exclusion. Review rental schedules and business-use records before estimating taxable gain.

Who reports the sale: the heir or the estate?
First determine who legally sold the property. If the executor or estate sold the home before distributing it, the transaction generally belongs on the estate’s return under the applicable rules. If the home was distributed to a beneficiary and the beneficiary later sold it, the beneficiary generally reports the sale. The property’s use while held by the estate can affect its treatment. Publication 559 discusses sales by estates and reporting on Form 8949 and Schedule D (Form 1041).
For an individual beneficiary, the IRS FAQ points to Schedule D (Form 1040) and/or Form 8949 when reporting is required. Publication 523 says a taxpayer who receives Form 1099-S generally must report the sale on Form 8949 even if there is no taxable gain. Match the sale documents to the correct seller and tax return; a Form 1099-S is a reporting document, not a determination of taxable gain.
What records should you gather before calculating?
Collect the records that establish each side of the calculation, not just the closing price. A complete file makes it easier to support both the inherited basis and later adjustments.
- Estate valuation: Ask the executor for the date-of-death or valid alternate-date appraisal, estate valuation, any relevant Form 706 value, and any Schedule A to Form 8971.
- Sale records: Keep the sale contract, closing statement, Form 1099-S, and proof of commissions and other selling expenses.
- Improvement records: Save receipts, invoices, permits, and descriptions of qualifying work, including evidence that improvements remained part of the home at sale.
- Rental or business-use records: Retain depreciation schedules and records of business or rental use, including depreciation allowed or allowable.
- Other basis adjustments: Keep records for casualty-loss deductions, insurance reimbursements, and relevant energy credits or subsidies.
- Ownership and transfer documents: Preserve deeds, trust documents, and records of any transfer of appreciated property to the decedent within a year of death.
If the estate value is unclear, ask the executor or estate tax preparer before using a figure. A retrospective appraisal may be needed to support FMV as of the relevant valuation date. For a straightforward estate and sale, the worksheet may be manageable; for joint or community property, trusts, rental use, or disputed valuations, a tax professional can help identify the proper taxpayer, basis, and reporting forms.
Common mistakes to avoid
- Using the decedent’s purchase price: The usual starting basis is the applicable estate FMV, not simply the decedent’s historical cost.
- Picking an alternate valuation date yourself: Only the estate’s personal representative can make the election under the governing rules.
- Subtracting the mortgage payoff from gain: Loan payoff affects cash at closing, not the general capital-gain formula.
- Adding repairs to basis: Routine maintenance generally does not qualify, although a repair within a larger qualifying project may be treated differently.
- Ignoring depreciation: Rental or business depreciation allowed or allowable can reduce basis even if no deduction was claimed.
- Assuming a long-term gain is tax-free: Long-term classification is not the same as exclusion from tax.
- Assuming inheritance guarantees the home-sale exclusion: The heir must meet applicable tests, and the home’s use can matter.
Frequently Asked Questions
What if the inherited house sells for less than its inherited basis?
A lower sale price does not automatically mean the loss is deductible. A loss on a personal-use home is generally treated differently from a loss on investment or business property, so the home’s use and the seller’s circumstances matter. Check the applicable IRS rules before claiming a loss.
Does the inherited basis include the value of furniture or other personal property sold with the house?
A sale may include items besides the real estate, and the contract or closing documents may allocate consideration among them. Do not assume the entire contract price belongs to the house; ask a tax professional how the allocation affects the real-estate calculation and any separately sold property.

A later sale may be relevant evidence, but it is not automatically the same as FMV on the date of death. Changes in condition, the real-estate market, and the time between valuation and sale can matter; retain an appraisal or other support for the applicable valuation date.
Do I have to report the sale if the home-sale exclusion eliminates all my gain?
A Form 1099-S generally means the sale must be reported on Form 8949, even when there is no taxable gain. Reporting requirements depend on the documents received and the facts, so verify the return instructions for the tax year involved.
