Fiduciaries managing estates and trusts are responsible for filing IRS Form 1041, U.S. Income Tax Return for Estates and Trusts. Unlike individual income tax returns, Form 1041 has distinct timelines, reporting responsibilities, and extension procedures. Missing these can lead to penalties and increased scrutiny from the IRS. This guide covers everything fiduciaries need to know in 2025 — from original filing due dates to Form 7004 extensions and the unique tax calendar of estates and trusts.
📆 What Is Form 1041?
Form 1041 is used to report income, deductions, gains, and losses of an estate or trust. It must be filed by the fiduciary (executor, trustee, or administrator) when the estate or trust earns gross income of $600 or more during the tax year or if a beneficiary is a nonresident alien. The fiduciary is also responsible for issuing Schedule K‑1s to beneficiaries for their share of income or deductions.
🗓️ Due Date for Filing Form 1041
The due date for Form 1041 depends on whether the estate or trust operates on a calendar year or fiscal year:
- Calendar-Year Estates and Trusts: Due by April 15, 2025.
- Fiscal-Year Estates and Trusts: Due by the 15th day of the 4th month following the end of the fiscal year.
- For example, if an estate’s fiscal year ends June 30, the return is due by October 15.
📝 Using Form 7004 to Request a 5½-Month Extension
Form 7004 allows fiduciaries to request an automatic 5½-month extension to file Form 1041. Key rules include:
- Form 7004 must be filed on or before the original due date of Form 1041.
- The extended deadline for a calendar-year trust would be September 30, 2025.
- Note: An extension of time to file is not an extension of time to pay any tax due. Interest and penalties still apply to unpaid balances.
📤 When Must Schedule K‑1s Be Issued to Beneficiaries?
Schedule K‑1 (Form 1041) reports each beneficiary’s share of the estate or trust income. Fiduciaries must provide beneficiaries with their K‑1s by the due date of Form 1041, including extensions:
- April 15, 2025 (or 4th month, 15th day after fiscal year-end).
- Extended date if Form 7004 is filed — e.g., September 30, 2025 for calendar-year filers.
💸 Estimated Tax Payments for Trusts and Estates
Trusts and estates may be required to make estimated tax payments if they expect to owe $1,000 or more in tax. Payments are made using Form 1041-ES and follow these deadlines for calendar-year taxpayers:
- April 15 – 1st installment
- June 15 – 2nd installment
- September 15 – 3rd installment
- January 15 of the following year – 4th installment
Fiduciaries must calculate these installments based on expected annual income to avoid underpayment penalties.
⏱️ Penalties for Late Filing or Non-Compliance
The IRS can impose penalties for late filing, late payment, or failure to furnish K‑1s:
- Late Filing: $245 per month (2025) for up to 5 months.
- Late Payment: 0.5% of the unpaid tax per month, up to 25%.
- Failure to Furnish K‑1s: $310 per beneficiary (2025), up to $3,783,000 per year.
