When an estate or irrevocable trust sells a decedent’s home, the fiduciary reports the sale of the residence on Form 1041 through a chain of forms: Form 8949 captures the transaction details, Schedule D categorizes the result as a long-term capital gain or loss, and Form 1041 pulls that number into the entity’s income and calculates the tax. The whole calculation turns on the property’s tax basis, which for inherited property is the fair market value on the date of death — not what the decedent originally paid.
Establishing the Property’s Basis
Under Section 1014, property acquired from a decedent takes a new basis equal to its fair market value on the date of death.1Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent This “step-up” applies whether the residence passed by will, through a revocable trust, or by another mechanism that required inclusion in the gross estate. The decedent’s original purchase price no longer matters.
The executor may instead elect the alternate valuation date under Section 2032, which values estate assets six months after death. The election is only available if it reduces both the gross estate and the total estate tax.2Office of the Law Revision Counsel. 26 USC 2032 – Alternate Valuation If the residence is sold inside that six-month window, the sale-date value is used.
Whichever date controls, a qualified independent appraiser should establish the value. The appraisal should follow the Uniform Standards of Professional Appraisal Practice and document the property, the method, the effective valuation date, and the appraiser’s credentials. That report is the estate’s primary defense if the IRS challenges the basis on audit.
Adjustments to Basis
Capital improvements made during administration — a new roof, an added room, a new HVAC system, a repaved driveway — increase basis.3Internal Revenue Service. Publication 551 – Basis of Assets Routine repairs do not. If the fiduciary rented the property before selling, any depreciation claimed on Form 4562 reduces basis.4Internal Revenue Service. 2025 Instructions for Form 4562 The resulting adjusted basis is one side of the gain calculation.
Calculating the Gain or Loss
Subtract the adjusted basis from the amount realized. The amount realized is the gross sales price minus the estate’s selling expenses: real estate commissions, legal fees, title transfer costs, and other charges tied to closing.5Internal Revenue Service. Publication 523 – Selling Your Home
Because of the step-up, many estate residence sales produce a modest gain or a loss. Only the appreciation between the date of death and the date of sale is taxed. If value dropped in that window, the result is a capital loss.
The Section 121 Exclusion Usually Does Not Apply
Individuals can exclude up to $250,000 of gain ($500,000 for married couples) on a principal residence if they owned and used the home for two of the preceding five years. Estates and non-grantor trusts are entities, not people. They cannot “use” a home as a residence, so the test fails at the entity level.6Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence – Editorial Notes A surviving spouse who inherits the home and sells it in their own name while still meeting the use test may claim the exclusion on a personal return, but the fiduciary filing Form 1041 generally cannot.
Filling Out Form 8949
Inherited property is treated as long-term regardless of the actual holding period, so the sale goes in Part II of Form 8949.7Internal Revenue Service. Instructions for Form 8949 Complete the columns as follows:
- Column (a): describe the property, typically the street address.
- Column (b): enter “INHERITED” in place of an acquisition date.
- Column (c): the date of sale.
- Column (d): the gross sales price, matching any Form 1099-S the closing agent issued.
- Column (e): the adjusted basis.
- Columns (f) and (g): any adjustment code and dollar amount. In the rare case Section 121 does apply, enter code “H” in (f) and the excluded gain as a negative number in (g).
- Column (h): the gain or loss, calculated as column (d) minus column (e), adjusted by column (g).
Carrying the Number to Schedule D and Form 1041
The Part II totals from Form 8949 flow to Part II of Schedule D (Form 1041). Short-term and long-term results combine in Part III to produce the net capital gain or loss for the year.8Internal Revenue Service. About Form 1041 – US Income Tax Return for Estates and Trusts
That net figure lands on Line 4 of Form 1041, joining interest, dividends, and other entity income. The total appears on Line 9. After allowable deductions — including the income distribution deduction for amounts carried to beneficiaries — Line 23 shows taxable income.9Internal Revenue Service. Instructions for Form 1041 and Schedules A, B, G, J, and K-1
How the Entity Is Taxed on the Gain
Estates and trusts reach the top bracket at a tiny income figure. For 2026:
- 10% on taxable income up to $3,300
- 24% from $3,301 to $11,700
- 35% from $11,701 to $16,000
- 37% above $16,000
Those rates govern ordinary income. Long-term capital gains from the residence sale are taxed at the preferential 0%, 15%, or 20% rates depending on the entity’s taxable income, and the 20% rate begins at the same $16,000 threshold where the 37% ordinary rate kicks in. Even at preferential rates, a meaningful gain retained inside the entity produces a substantial bill because so little income is required to hit the top tier.
Net Investment Income Tax
On top of the capital gains rate, the entity may owe the 3.8% Net Investment Income Tax on the lesser of its undistributed net investment income or its adjusted gross income above the top-bracket threshold.10Internal Revenue Service. Topic No. 559 – Net Investment Income Tax For 2026 that threshold is $16,000. Capital gain from the residence counts as net investment income, so retaining a significant gain inside the entity almost always triggers the NIIT.11Internal Revenue Service. Instructions for Form 8960 – Net Investment Income Tax The tax is calculated on Form 8960 and added to the Form 1041 liability. If Section 121 validly reduces the gain, the excluded portion is not net investment income.
Whether the Gain Stays With the Entity or Goes to Beneficiaries
Capital gains are generally treated as principal (corpus) of the trust or estate and are excluded from distributable net income. DNI is the ceiling on income that can be taxed to beneficiaries, so gains outside DNI stay taxed at the entity level. Given the compressed brackets and the NIIT, that often produces a higher combined rate than spreading the gain across beneficiaries’ individual returns.
Gains can be included in DNI and passed through in limited circumstances: when the governing instrument or state law allocates gains to income rather than principal, when the fiduciary has a consistent practice of treating gains as part of distributions, or when the gains are actually distributed to beneficiaries during the year. Without that authority, the default is that gains — and the tax on them — stay with the entity. When gains do pass through, the beneficiary reports them on Schedule D of their own Form 1040 based on the Schedule K-1 issued by the fiduciary.12Internal Revenue Service. 2025 Instructions for Schedule K-1 (Form 1041) for a Beneficiary Filing Form 1040 or 1040-SR
The 65-Day Election
Section 663(b) lets a fiduciary treat distributions made in the first 65 days of the following tax year as if made on the last day of the current year. For a calendar-year estate, distributions through early March can count against the prior year. The election is made by checking a box on Form 1041 and is irrevocable for that year. It gives a fiduciary a second look after year-end at whether pushing the gain to beneficiaries produces a better result, but only when the governing instrument or state law allows capital gains into DNI in the first place.
Estimated Tax Payments
A residence sale is often the entity’s largest taxable event of the year. If the estate or trust expects to owe $1,000 or more after withholding and credits, the fiduciary must make quarterly estimated payments on Form 1041-ES.13Internal Revenue Service. 2026 Form 1041-ES The safe harbor mirrors the individual rule: pay the lesser of 90% of the current year’s tax or 100% of the prior year’s.14Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty A newly created estate has no prior-year return, so the 100%-of-prior option is not available and the current-year projection has to carry the weight. When the sale closes late in the year, the annualized income installment method on Form 2210 can reduce or eliminate the penalty by showing income was earned unevenly.
When the Sale Produces a Loss
If the adjusted basis exceeds the amount realized, the entity has a capital loss. Deductibility depends on how the property was used. An estate holding a home for liquidation and distribution is generally treated as holding it for investment, and the loss offsets other capital gains plus up to $3,000 of ordinary income per year, the same as for an individual investor.
If a beneficiary was living in the property rent-free during administration, the IRS may recharacterize it as personal-use, making the loss nondeductible. The distinction matters, and fiduciaries should document the purpose for which the property was held. Any capital loss carryover remaining when the estate or trust terminates passes to the beneficiaries on Schedule K-1, Box 11, Codes C and D.12Internal Revenue Service. 2025 Instructions for Schedule K-1 (Form 1041) for a Beneficiary Filing Form 1040 or 1040-SR
