Capital gains and losses for an estate or trust are reported on Schedule D of Form 1041, which sorts each sale into short-term or long-term, nets the two, and produces a figure that either flows onto the entity’s taxable income or gets allocated out to beneficiaries. The stakes are unusually high on a 1041 Schedule D because fiduciary brackets are compressed: for 2026, an estate or trust hits the top 37% federal rate at just $16,000 of taxable income.1Internal Revenue Service. 2026 Form 1041-ES That single fact drives most of the decisions on the form.
What Belongs on Schedule D
Schedule D captures the sale or exchange of capital assets held by the estate or trust. A capital asset is defined broadly and covers most of what a fiduciary actually sells: stocks, bonds, mutual fund shares, and real estate held for investment. Inventory, depreciable business property, and certain receivables are excluded and produce ordinary income reported elsewhere on Form 1041.2Office of the Law Revision Counsel. 26 U.S. Code 1221 – Capital Asset Defined
A few less obvious events also belong here. Involuntary conversions of investment property, such as insurance proceeds from a destroyed asset, are Schedule D transactions. So is a redemption of stock or bonds that doesn’t qualify as a dividend. A nonbusiness bad debt that becomes completely worthless is treated as a short-term capital loss.3Internal Revenue Service. Topic No. 453, Bad Debt Deduction
One trap catches many fiduciaries. If the will leaves a fixed-dollar bequest (“$50,000 to my nephew”) and the executor satisfies it by distributing stock worth $50,000, the estate is treated as having sold that stock at fair market value on the transfer date. The difference between that value and the estate’s basis is a reportable gain or loss.
Figuring Basis Before You Can Figure the Gain
The entire calculation hinges on basis, and the rules for fiduciary entities differ from what individual taxpayers know. How the asset entered the estate or trust controls.
Inherited Assets
Property the decedent owned at death generally gets a new basis equal to its fair market value on the date of death, under Section 1014.4Office of the Law Revision Counsel. 26 U.S. Code 1014 – Basis of Property Acquired From a Decedent Stock the decedent bought for $10,000 that was worth $80,000 at death has an estate basis of $80,000. A later sale at $82,000 produces only a $2,000 gain.
The executor can elect an alternate valuation date six months after death, with any asset distributed before that date valued on the distribution date instead.5Office of the Law Revision Counsel. 26 U.S. Code 2032 – Alternate Valuation The election is only available when it decreases both the gross estate and the estate tax owed, and it applies to all assets or none.
Inherited assets also get an automatic long-term holding period, so every inherited asset qualifies for long-term rates even if sold the day after death.6Office of the Law Revision Counsel. 26 U.S. Code 1223 – Holding Period of Property
Gifted Assets
Assets a grantor transfers into a trust by lifetime gift carry over the grantor’s original basis.7Office of the Law Revision Counsel. 26 U.S. Code 1015 – Basis of Property Acquired by Gifts and Transfers in Trust Shares the grantor bought for $25,000 and gifted when worth $60,000 give the trust a $25,000 basis. If fair market value at the gift date was below the donor’s basis, the trust must use that lower value when calculating a loss on a later sale.
Basis Consistency When the Estate Files Form 706
If the estate is large enough to require a federal estate tax return, the executor must also file Form 8971 and give each beneficiary a Schedule A showing the basis of assets they received. A beneficiary cannot later claim a higher basis than what appears on that Schedule A.8Internal Revenue Service. Instructions for Form 8971 and Schedule A The requirement doesn’t apply when the gross estate plus adjusted taxable gifts is below the basic exclusion amount, or when the 706 is filed only for a GST election or portability.
Whatever the source of basis, adjust it before putting it on Schedule D. Capital improvements increase basis; depreciation deductions reduce it. The adjusted figure is what the form wants.
Working Through Parts I, II, and III
Schedule D has three parts that sort transactions and then combine them.
Part I covers short-term transactions, meaning assets held for one year or less. Individual sales are detailed on Form 8949, and the totals flow into Part I. The section nets short-term gains against short-term losses to produce a single net short-term figure.9Internal Revenue Service. Schedule D (Form 1041) – Capital Gains and Losses
Part II does the same for long-term transactions, meaning assets held more than a year. Every inherited asset lands here regardless of actual holding time. This part also captures unrecaptured gain from the sale of depreciable real property, which faces a maximum 25% rate.10Internal Revenue Service. Topic No. 409, Capital Gains and Losses
Part III combines the two nets into a single result. A net gain carries to Line 4 of Form 1041 and adds to the entity’s taxable income. A net loss lets the entity deduct up to $3,000 against ordinary income, with any excess carrying forward. When the estate or trust terminates, any unused loss carryover passes through to the beneficiaries on the final return.
The Rate Problem When the Entity Keeps the Gain
Fiduciary brackets are compressed to an extreme degree. An individual doesn’t reach the 37% ordinary rate until taxable income exceeds roughly $600,000; an estate or trust reaches it at $16,000. Preferential long-term capital gains rates (0%, 15%, 20%) still apply, but the brackets are compressed on the same pattern, with the 20% rate kicking in near where the 37% ordinary bracket begins.
On top of that, the 3.8% Net Investment Income Tax hits capital gains that the entity retains rather than distributes. The surtax applies to the lesser of undistributed net investment income or the amount by which adjusted gross income exceeds the top-bracket threshold, $16,000 for 2026. The fiduciary calculates it on Form 8960.11Internal Revenue Service. Instructions for Form 8960 Net Investment Income Tax — Individuals, Estates, and Trusts
Stacked, a trust that retains long-term gains can face 23.8% federal (20% plus 3.8%). Short-term gains retained by the entity can be taxed at 40.8% (37% plus 3.8%). Those numbers are why the allocation decision matters so much.
Pushing Gains Out to Beneficiaries
Gains don’t have to stay trapped inside the entity. Whether they can be pushed out to beneficiaries through Distributable Net Income follows a hierarchy.
The governing document controls first. If the will or trust agreement treats capital gains as distributable income rather than principal, those gains can be included in DNI and allocated to beneficiaries. If the document is silent, state law fills the gap; most states follow some version of the Uniform Principal and Income Act, which typically classifies capital gains as principal and keeps them with the entity.
Capital gains are also included in DNI when they are actually distributed to a beneficiary, permanently set aside for a beneficiary, or used in determining the amount to be distributed. A fiduciary with discretion under the trust document to allocate gains to income has a real planning tool. Pushing gains to a beneficiary in a lower bracket often produces meaningful savings compared with paying at the entity level.
Capital losses work differently. They stay with the estate or trust to offset future gains and generally aren’t distributable during the entity’s existence. The exception is termination: any remaining loss carryover passes through to beneficiaries on the final return.
Whatever the fiduciary decides, ground the allocation in the governing document, state law, or a consistent prior practice, and document the basis for it.
Reporting the Beneficiary’s Share on Schedule K-1
Once the split is set, each beneficiary’s share goes on Schedule K-1 (Form 1041). The character of the gain carries through, so short-term stays short-term and long-term stays long-term on the beneficiary’s Form 1040.
- Box 3: net short-term capital gain allocated to the beneficiary
- Box 4a: net long-term capital gain allocated to the beneficiary
- Box 11, Codes C and D: unused capital loss carryover, reported only in the year the entity terminates
Beneficiaries carry these figures to their own Schedule D. A loss carryover passed through on termination is still subject to the $3,000 annual deduction limit on the beneficiary’s individual return.12Internal Revenue Service.

Deadlines and Penalties
Form 1041, along with Schedule D, Form 8949, and each Schedule K-1, is due by the 15th day of the fourth month after the close of the entity’s tax year. For a calendar-year estate or trust, that’s April 15.13Internal Revenue Service. Forms 1041 and 1041-A: When to File The fiduciary can get an automatic extension by filing Form 7004 before the original due date, but an extension of time to file is not an extension of time to pay.14Internal Revenue Service. About Form 7004, Application for Automatic Extension of Time To File Certain Business Income Tax, Information, and Other Returns
Each beneficiary must receive a K-1 by the same date the 1041 is due. The penalty for failing to furnish a correct K-1 on time can reach $310 per statement, with reductions if the fiduciary fixes the error quickly, and higher amounts for intentional disregard.
The failure-to-file penalty for the return itself is 5% of the unpaid tax for each month or partial month the return is late, capped at 25%. If the return is more than 60 days late, the minimum penalty for returns due after December 31, 2025, is $525 or 100% of the unpaid tax, whichever is less.15Internal Revenue Service. Failure to File Penalty Interest on the unpaid balance runs on top. If tax will be owed, pay an estimate by the original due date even when filing on extension.
