How to file a tax extension for an estate or trust (Form 1041)

Who files Form 7004 for an estate or trust?

The fiduciary — the executor or administrator of an estate, or the trustee of a trust — files Form 7004 in the name of the estate or trust, using its own EIN (Employer Identification Number). Form 1041 is required for a domestic estate with gross income of $600 or more, and for a domestic trust with any taxable income, gross income of $600 or more, or a nonresident alien beneficiary. Form 7004 uses a separate two-digit form code for an estate, a trust, and a bankruptcy estate.

Grantor trusts are the common exception. A revocable living trust, while the grantor is alive, reports its income on the grantor's own Form 1040 and usually files no Form 1041. When a revocable trust becomes irrevocable at the grantor's death, it generally needs a new EIN. It may then have a Form 1041 filing requirement, although a qualified revocable trust may instead make a section 645 election to be treated as part of the related estate during the election period.

When is the Form 1041 deadline?

For calendar-year estates and trusts, Form 1041 is due Thursday, April 15, 2027 in the 2027 season, and Form 7004 must be filed by that date. The extension moves the filing deadline to Thursday, September 30, 2027.

Estates may choose a fiscal year, ending on the last day of a month, provided the estate's first tax year does not exceed 12 months. Its first tax year begins on the date of death, so the first return may cover a short period. Whatever year-end the estate picks, Form 1041 is due the 15th day of the 4th month after the year ends: a June 30 year-end files or extends by October 15 and has until March 31. Most trusts must use a calendar year. The main exception is a qualified revocable trust that makes the Section 645 election to be treated as part of the estate; the combined filing then uses the estate's fiscal year.

How long is the Form 1041 extension?

For an estate other than a bankruptcy estate, or for a trust, the automatic Form 7004 extension is 5½ months. A bankruptcy estate filing Form 1041 receives a six-month extension. Form 7004 gives most business returns six months, but for Form 1041 filed by an estate (other than a bankruptcy estate) or a trust it is 5½ months — Thursday, September 30, 2027 for a calendar-year filer, two weeks before the October 15, 2027 date that individuals and C corporations get. The exception is a bankruptcy estate: an individual's Chapter 7 or Chapter 11 bankruptcy estate files Form 7004 with the bankruptcy-estate code and gets six months.

How to file your Form 1041 extension

1. 1

   Choose estate, trust, or bankruptcy estate

   Pick the Form 1041 filer type; we map it to the right Form 7004 code, which also sets the extension length.

2. 2

   Enter the fiduciary's details

   Name of the estate or trust, its EIN, its mailing address, and the tax year — calendar or the estate's fiscal year.

3. 3

   Estimate the tax

   Tentative total tax (an estimate of the year's tax), payments and credits, and the balance due. The balance due may be reduced when the estate or trust qualifies for an income distribution deduction, but distributions do not necessarily reduce the tax to zero; make a proper estimate under the rules that apply to the estate or trust.

4. 4

   Pay the fee and we e-file

   $9.95, shown before you pay. We transmit directly to the IRS and email you the moment the extension is accepted.

Does the extension cover the Schedule K-1s and the beneficiaries' returns?

It covers the Schedules K-1, not the beneficiaries' own returns. Schedules K-1 (Form 1041), which report each beneficiary's share of the income, are part of the return, so an extended Form 1041 also extends the date by which the fiduciary must send them. A beneficiary waiting on a K-1 must still file their own Form 4868 by Thursday, April 15, 2027 if they need more time on their Form 1040. Because a Schedule K-1 from an extended estate or trust may not be available by the beneficiary's regular filing deadline, an individual beneficiary who cannot accurately complete their return without it may need to file Form 4868; IRS Free File files Form 4868 at no charge.

Is this the same as an estate tax extension?

No. Form 1041 reports the income an estate or trust earns after the date of death — interest, dividends, rent, gains on sales. Form 706 is the federal estate tax return. For a U.S. citizen or resident dying in 2026, it generally must be filed when the decedent's gross estate plus adjusted taxable gifts and any applicable specific exemption exceeds the $15 million basic exclusion amount. An estate may also file Form 706 even when it is below that threshold in order to elect portability of a deceased spouse's unused exclusion. Form 706 is due nine months after the date of death and is extended with Form 4768, not Form 7004; we do not file Form 4768. Most estates never file a Form 706; many file a Form 1041, because the estate earned income while it was open.

Does an estate or trust owe tax with the extension?

Yes, if it kept income rather than distributing it. An estate or trust may receive an income distribution deduction for amounts distributed, credited, or required to be distributed to beneficiaries, subject to the distributable net income rules. Beneficiaries generally include their taxable share of those amounts in income, while taxable income retained by the estate or trust is generally taxed to the entity. Any tax due must be paid by the original due date — April 15, 2027 for calendar-year filers — because the extension only extends the filing date. Interest and the failure-to-pay penalty run from that date on any unpaid balance. Pay the balance to the IRS through EFTPS or as the Form 7004 instructions allow; our fee covers the extension filing only. See does an extension extend the payment deadline?

Who signs, and which taxpayer ID goes on the form?

The fiduciary files, and the EIN belongs to the estate or trust — not the decedent. Form 7004 has no signature line; the executor, administrator, or trustee files it. An estate needs its own EIN, obtained free from the IRS online or with Form SS-4; the decedent's Social Security number is used for their final Form 1040, never for Form 1041. A trust that becomes irrevocable at the grantor's death also needs a new EIN, even if it reported under the grantor's SSN while revocable.

What if the fiduciary misses the deadline?

A late Form 7004 is generally not accepted, and Form 1041 is late until it is filed. The failure-to-file penalty is 5% of the unpaid tax for each month or part of a month, up to 25%, reduced by the failure-to-pay penalty in months where both apply. If no tax is owed, the percentage-based failure-to-file penalty may be zero. However, late or incorrect Schedules K-1 can create separate information-reporting penalty exposure. See the missed-deadline guide and the penalties guide.

How much does a Form 1041 extension cost?

A flat $9.95 for Form 7004 — one price, shown before you pay, no subscription — and if the IRS rejects the extension and we cannot get it accepted, we refund the fee. Filing on paper is free apart from postage; IRS Free File covers personal Form 4868 extensions, not Form 7004.
