Form 1041 for an Estate: A Plain-English Guide for Executors

Does the estate need to file Form 1041?

When someone dies, their estate becomes a separate taxpayer. Everything the person earned up to the date of death goes on their final Form 1040. Everything their property earns after that, until it is handed to the heirs, belongs to the estate and goes on Form 1041, the U.S. Income Tax Return for Estates and Trusts.

The executor (or administrator, or whoever is in possession of the property if no one was appointed) must file Form 1041 for a tax year when the estate has:

• Gross income of $600 or more, whatever its taxable income. Gross income means income before deductions, and for a sale it means the gain, not the sale price.
• A beneficiary who is a nonresident alien, with any amount of income.

Common ways an estate crosses $600: a savings or brokerage account that stays in the person's name for months, a final paycheck or bonus paid after death, rent from a house, a sale of stock or real estate at a gain, or retirement money paid to the estate because no beneficiary was named. Assets that pass straight to a named beneficiary (life insurance, payable-on-death accounts, IRAs with a beneficiary) never belong to the estate and don't go on its 1041.

The estate needs its own EIN before it files; you can't use the person's Social Security number. See how to get an EIN for an estate.

When Form 1041 is due, and the extension

A due date on a Saturday, Sunday or legal holiday moves to the next business day. Form 7004 must be filed by the original due date; it is automatic, but it extends only the filing date. Pay your best estimate of the tax by the original date to avoid interest and the late-payment penalty. Schedules K-1 must reach the beneficiaries by the date the return is due; the penalty is $340 per missing or wrong K-1.

Estimated tax. An estate does not pay quarterly estimated tax for any tax year that ends before the second anniversary of the death. An estate that stays open longer and expects to owe $1,000 or more uses Form 1041-ES after that.

Calendar year or fiscal year?

Unlike a person, an estate can choose a fiscal year. The executor picks it simply by filing the first Form 1041: the first tax year starts on the date of death and can end on the last day of any month, as long as it is not longer than 12 months. Every later year is 12 months ending in that month.

Why executors pick a fiscal year:

• One return instead of two. Someone who died in October can choose a year ending September 30 of the next year. If the estate is wound up by then, there is one Form 1041, not one for the short year to December and another for the next year.
• Deferral for beneficiaries. A beneficiary reports estate income for the year in which the estate's tax year ends. A distribution made in February 2026 by an estate whose tax year ends January 31, 2027 is reported on the beneficiary's 2027 return, due in April 2028, not on their 2026 return.
• Bunching deductions. Choosing the year end to fall after big expenses (executor and attorney fees, the final appraisals) can match deductions to the income they offset.

A calendar year is simpler when the estate will stay open for several years or a trust that must use the calendar year will join the estate under a section 645 election. Use the calculator above to compare due dates.

What income goes on Form 1041

• Interest and dividends on accounts and investments the estate holds. Ask banks and brokers to retitle accounts under the estate's EIN so 1099s match the 1041.
• Capital gains and losses from selling the person's property. Basis is generally the fair market value on the date of death, so a sale soon after death produces little gain. See valuation and the date-of-death value.
• Rent from real estate the executor manages, with its expenses and depreciation.
• Income in respect of a decedent (IRD): money the person had earned but not received, such as a final paycheck, bonus, deferred compensation, or an IRA or 401(k) paid to the estate. IRD does not get a stepped-up basis and is fully taxable. If the estate also paid federal estate tax, the section 691(c) deduction offsets part of it.
• Business income from a sole proprietorship, partnership or S corporation interest the estate holds.

Deductions an estate can take

• A $600 exemption (line 21), in place of the standard deduction individuals get.
• Administration expenses that would not have been incurred if the property were not held by an estate: executor fees, attorney and accountant fees, court costs, appraisal fees. These can be deducted on Form 1041 or on Form 706, not both. If there is no estate tax, take them on the 1041.
• Interest, state and local taxes, and investment expenses the estate paid.
• The income distribution deduction for income paid or credited to beneficiaries (next section).
• Charitable set-asides required by the will.

Funeral costs and the person's medical bills are not deductible on Form 1041. Funeral costs can go on Form 706 only. Medical bills paid within a year of death can be deducted on the final Form 1040 or on Form 706.

Distributions, DNI and Schedule K-1

An estate is a pass-through for income it distributes. On Schedule B the executor figures distributable net income (DNI), which caps the income distribution deduction. Whatever income is paid out (up to DNI) is deducted by the estate and taxed to the beneficiaries, who get a Schedule K-1 showing their share by type: interest, dividends, capital gains (usually only in the final year), rental income.

This matters because estate tax brackets are compressed. An estate reaches the 37% bracket above $16,000 of taxable income in 2026 ($16,500 in 2027); a single person does not reach it until $640,600 ($661,375 in 2027). Distributing income to beneficiaries in lower brackets usually lowers the family's total tax.

The 65-day rule. The executor can elect to treat distributions made in the first 65 days after the tax year ends as if made on the last day of that year (section 663(b)). It lets you decide how much income to push out after you know the year's numbers. The election is made on a timely filed Form 1041 and cannot be revoked.

Estate income tax rates (2026 and 2027)

The schedule follows the estate's tax year, not the date of death. An estate tax year that begins in 2026 uses the 2026 rates, even when it ends in 2027 (a fiscal year). Tax years beginning in 2027 use the 2027 rates, published in Rev. Proc. 2026-35.

Example: an estate that keeps $20,000 of interest and rental income (after the exemption and expenses) owes about $5,331 of regular federal tax for 2026 ($5,263 for a tax year beginning in 2027). The same income spread to two beneficiaries would usually be taxed at their own rates. Qualified dividends and long-term gains get the 0%, 15% and 20% rates, and the 3.8% net investment income tax applies to undistributed investment income above $16,000 ($16,500 for 2027). Sources: Rev. Proc. 2025-32 (2026 inflation adjustments) and Rev. Proc. 2026-35 (2027 inflation adjustments).

The final Form 1041

When the estate distributes everything and closes, check the "Final return" box. In the final year, the estate's capital gains pass to the beneficiaries, and so do any unused capital loss and net operating loss carryovers and "excess deductions on termination" (deductions larger than the final year's income), reported on their K-1s in box 11.

Before the last distribution, keep a reserve for this return and any tax. To shorten how long the IRS can assess more income tax, the executor can file Form 4810 (request for prompt assessment, which cuts the period to 18 months) and Form 5495 (request for discharge from personal liability).

How to file: step by step

1. Get the estate's EIN and file Form 56 so IRS notices come to you.
2. Move income-producing accounts into the estate's name and EIN, and run every receipt and expense through the estate bank account.
3. Pick the tax year end, then total gross income for that year. Under $600 and no nonresident alien beneficiary: no return for that year.
4. List deductions (fees, interest, taxes) and decide whether administration expenses go on the 1041 or the 706.
5. Decide what to distribute, including within the 65-day window, and complete Schedule B and the K-1s.
6. Figure the tax on Schedule G, sign as fiduciary, and file by paper or through a professional who can e-file Form 1041. Send each beneficiary their K-1.
7. File the state fiduciary return too, if the state has an income tax. Most do.
