Read our full article for in-depth instructions and additional FAQs.
What Form 1041 is (and what it is not)
Form 1041 is the U.S. Income Tax Return for Estates and Trusts. It reports income earned by a decedent’s estate (or certain trusts) after the date of death and before assets are distributed to beneficiaries.
Though they may be similar, keep in mind that Form 1041 differs from these two forms:
- Form 1040: the deceased person’s final individual return for income earned while they were alive.
- Form 706: a one-time estate tax return (about total asset value at death and possible estate tax).
Who has to file it?
Typically, the fiduciary (executor, administrator, or trustee) files Form 1041.
You generally must file Form 1041 for a domestic estate that has:
- $600 or more in gross income for the tax year, or
- a beneficiary
The schedules you'll hear about the most
A few common pieces that come up a lot:
- Schedule K-1 (Form 1041): shows each beneficiary’s share of income, deductions, credits, etc. Beneficiaries use it on their own return.
- Schedule D: capital gains and losses (if applicable).
- Schedule A: charitable deduction (not for every trust situation).
- Schedule B: income distribution deduction.
Deadlines: calendar year vs fiscal year
The due date depends on the estate or trust tax year:
- Calendar year: generally due April 15
- Fiscal year: due on the 15th day of the 4th month after the tax year ends
Need more time? You can request an automatic extension using Form 7004 (this can give you an additional 5 months to file).
