What Form 1041 is for
Form 1041 is the federal income tax return for a decedent's estate, a trust, or a bankruptcy estate. The fiduciary uses it to report the entity's income, deductions, gains and losses, the income that was accumulated or paid out to beneficiaries, any income tax owed, employment taxes on wages paid to household employees, and the Net Investment Income Tax.
You file it if you are the fiduciary, meaning a trustee, executor, administrator, personal representative, or person in possession of a decedent's property. A trust or estate is a separate legal entity for tax purposes. It gets a deduction for income distributed to beneficiaries, and Schedule K-1 tells each beneficiary what to include on their own return.
Who has to file Form 1041?
File for a domestic decedent's estate if it had gross income of $600 or more for the tax year, or if a beneficiary is a nonresident alien. File for a domestic trust taxable under section 641 if it had any taxable income, gross income of $600 or more no matter what its taxable income was, or a nonresident alien beneficiary. Either way, you also have to file if you held a qualified investment in a qualified opportunity fund at any time during the year, with Form 8997 attached.
- Bankruptcy estate of an individual under chapter 7 or 11: the trustee or debtor-in-possession files if gross income is $15,750 or more
- Foreign estate or foreign trust: file Form 1040-NR instead of Form 1041
- Charitable remainder trust under section 664: files Form 5227, not Form 1041
- Common trust fund maintained by a bank: does not file Form 1041
- Pre-need funeral trusts electing section 685 treatment: file Form 1041-QFT
When is Form 1041 due?
Calendar year estates and trusts file Form 1041 and any Schedules K-1 by April 15, 2026. If the estate or trust uses a fiscal year, the return is due on the 15th day of the 4th month after the tax year closes. An estate with a tax year ending June 30, 2026, files by October 15, 2026. If the due date falls on a Saturday, Sunday, or legal holiday, file on the next business day. You must pay the tax in full when the return is filed.
- Need more time? Form 7004 gets an automatic 5 1/2 month extension to file
- A bankruptcy estate uses Form 7004 for an automatic 6 month extension
- Interest is charged on tax not paid by the due date even if you got an extension to file

How do you fill out Form 1041?
Start with the entity information: the exact name from the Form SS-4 you used to get the EIN, the fiduciary's name and title, and the address. Check every box in item A that describes the entity, since more than one can apply. Then work down page 1. Lines 1 through 8 report income, and line 9 totals it. Lines 10 through 15b are deductions. Lines 18 through 21 cover the distribution deduction, the estate tax deduction, the qualified business income deduction, and the exemption.
Before you prepare the form, figure the accounting income of the estate or trust under the will or trust instrument and local law, because the income distribution deduction depends in part on that amount. Review the will or trust instrument, including any amendments or codicils. The exemption on line 21 is $600 for a decedent's estate, $300 for a trust required to distribute all income currently, $5,100 for a qualified disability trust, and $100 for any other trust. The fiduciary, or an authorized representative, signs the return. If there are joint fiduciaries, only one has to sign.
- Attach Schedule A for the charitable deduction, unless you file for a simple trust or pooled income fund
- Complete Schedule B if the estate or trust was required to distribute income currently, or paid or credited any other amounts to beneficiaries
- Schedule G, Part I figures the total tax, and Part II adds up the payments
- Give a Schedule K-1 to each beneficiary who received a distribution of property or an allocation of an item, on or before the day you file
- You may round cents to whole dollars, but if you round one amount you must round all of them
What changed on the 2025 Form 1041?
The form now has direct deposit fields. If line 29 shows an overpayment and you want it refunded on line 30b, fill in the routing number, account type, and account number on lines 30c, 30d, and 30e. Two lines were added for section 1062, which lets you elect to pay the net income tax on gain from selling qualified farmland property to qualified farmers in four equal annual installments. Report the full liability on Schedule G, Part II, line 18c, and the first installment on page 1, line 25b.
The State and Local Tax Deduction Worksheet was revised, which may change the calculation for filers with adjusted gross income of more than $500,000. Lines 4, 6, and 7 changed, and a new line 8 now holds the deduction amount. If you already filed your 2025 Form 1041 using the old worksheet and the new one gives you a bigger deduction, file an amended 2025 Form 1041.
- A qualified disability trust can claim an exemption of up to $5,100, with no phaseout

- The 20% maximum capital gains rate applies to income above $15,900. The 0% rate applies up to $3,250, and the 15% rate applies over $3,250 and up to $15,900
- Form 8879-F can be used with only one Form 1041. It can no longer cover multiple Forms 1041
