Treasury IRS Form 1041-T is used for Allocation of Estimated Tax Payments to Beneficiaries (Under Code section 643(g)). This form must be filed by the 65th day after the close of the tax year.
Plain English
This form allows a trust or decedent’s estate to decide that some of its estimated tax payments were actually made by one or more beneficiaries. By filing Form 1041-T, the fiduciary officially makes this election, which cannot be changed later. This ensures the correct person receives credit for those tax payments.

This form allows a trust or decedent’s estate to decide that some of its estimated tax payments were actually made by one or more beneficiaries. By filing Form 1041-T, the fiduciary officially makes this election, which cannot be changed later. This ensures the correct person receives credit for those tax payments.
A trust or decedent’s estate must file IRS Form 1041-T to elect that parts of its estimated tax payments are treated as made by a beneficiary or beneficiaries.
The form collects details such as the total amount of estimated taxes (Line 1), and provides an array listing each beneficiary's name, address, identifying number, allocated amount (Column d), and proration percentage (Column e).
For a calendar year 2025, the election must be filed by March 6, 2026. The form covers fiscal years beginning in 2025 and ending in 2026.
If mailing to an address, mail it to Internal Revenue Service, Tax Forms and Publications Division, 1111 Constitution Ave. NW, IR-6526, Washington, DC 20224. The form should be attached to Form 1041 if filing with that return.
First, fill in the trust/estate's information (like EIN) on Page 1. Then, list each beneficiary using Line 2, ensuring the total allocated amount matches Line 1. Finally, the fiduciary must sign and date the form before sending it.
The fiduciary declares under penalties of perjury that the allocation is true, correct, and complete; failure to do so means the declaration may not be upheld.
The instructions state to attach it to Form 1041 only if making the election with that form; otherwise, file Form 1041-T alone. Check the 'How To File' section on Page 2.
