Updated August 3, 2026. Quick answer: an estate files Form 1041 if it had gross income of $600 or more for the tax year, or if it has any beneficiary who is a nonresident alien. That second prong has no dollar floor at all — it applies regardless of income.
The filing test
Gross income for the tax year of $600 or more. A beneficiary who is a nonresident alien. … For fiscal-year estates and trusts, file Form 1041 by the 15th day of the 4th month following the close of the tax year.
— IRS Instructions for Form 1041, ‘Who Must File’
Read the two prongs separately, because they are joined by or:
- Gross income of $600 or more for the tax year. That is a statutory threshold in the instructions, not an annually indexed figure — but check the current instructions rather than this page.
- A beneficiary who is a nonresident alien, with no income threshold whatsoever. An estate with a single overseas beneficiary and trivial income can still have a filing requirement. This is the prong people miss.
This is not the decedent’s final return
Two different returns, and confusing them is the common error:
| Final Form 1040 | Form 1041 | |
|---|---|---|
| Whose income | The person’s, up to the date of death | The estate’s, after death |
| Filed under | The decedent’s SSN | The estate’s EIN |
| Who files | The personal representative on their behalf | The estate as a separate taxpayer |
The decedent’s final return covers the period ending at death. Everything the estate earns afterwards — interest, dividends, rent, gain on a sale during administration — belongs on the 1041.
The fiscal-year option
An estate is not locked to the calendar year; the instructions set filing deadlines for fiscal-year estates, which is the ability to choose a year ending in a month other than December. Choosing well can shift income between years and simplify a short administration.
What we could not confirm. We verified both filing prongs verbatim from the instructions’ own Who Must File section, and the existence of fiscal-year estates from their filing-deadline language. We could not retrieve the accounting-periods section stating the election rule itself — the page truncated on repeated attempts. Treat the fiscal-year option as real but confirm how and when the election is made before relying on it.
Where the money actually goes
An estate can either keep income or distribute it, and that choice moves the tax. Income distributed to beneficiaries is generally taxed to them rather than to the estate, which matters because estate tax brackets compress very quickly — an estate reaches high rates at income levels an individual would barely notice.
That interaction is genuinely technical and is where a preparer earns their fee on any estate with real income.

Probate is STATE law and the order in which claims are paid differs between states; the federal priority rule described here applies everywhere, but the state ordering below it does not. An executor who pays the wrong claim first can become personally liable, which is why this wing exists. We sell nothing and refer you nowhere for a fee.
