Updated October 18, 2026. Quick answer: Line 1 of Form 1041-T is the total of estimated tax payments the trust or estate elects to pass to beneficiaries. Line 2 splits it among beneficiaries by name, taxpayer number, amount and percentage, line 3 picks up any extra sheets, and line 4 must equal line 1. Each beneficiary’s amount is also reported on Schedule K-1 box 13 with code A.
What the lines ask for
This page covers the form’s entries on the front of the Form 1041-T form. The captions run in order. Line 1 is “Total amount of estimated taxes to be allocated to beneficiaries.” Line 2 is “Allocation to beneficiaries:” with ten numbered rows. Line 3 is “Total from additional sheet(s)” and line 4 is “Total amounts allocated. (Must equal line 1, above.)”.
The address block
The block at the top is for the fiduciary and applies only when the form is filed on its own. The instructions say “Include the suite, room, or other unit number after the street address.” They continue “If the post office doesn’t deliver mail to the street address and the fiduciary has a P.O. box, show the box number instead of the street address.” The form also has a box to check “If you are filing this form for the final year” of the estate or trust.
Line 1: the total
“Enter the amount of estimated tax payments made by the trust or decedent’s estate that the fiduciary elects to treat as a payment made by the beneficiaries.” The figure comes from the estimated tax payments the trust or estate made, as shown in its payment records. One category of payment cannot be included: “You can’t allocate to a beneficiary tax withheld from income, such as withholding from lottery or other gambling winnings, or from salary or pension payments reported on Form 1041.” “You must report this withholding on Form 1041, Schedule G, Part II, line 14.”
Line 2: columns (b) to (e)
Column (b) is the name and address. “Group the beneficiaries to whom you are allocating estimated tax payments into two categories.” “First, list all the individual beneficiaries. Then, list all the other beneficiaries.”
Column (c) is the identifying number. “This is generally the social security number (SSN) for individuals or employer identification number (EIN) for all other entities.” “Failure to enter a valid SSN or EIN may cause a delay in processing and could result in penalties being imposed on the beneficiary.” For beneficiaries who file jointly, “you can assist the IRS in crediting the proper account by also providing the SSN, if known, of the beneficiary’s spouse.”
Column (d) is the amount allocated to that beneficiary. “For each beneficiary, also report this amount in box 13 of Schedule K-1 (Form 1041), using code A.” The box and code are explained on the Schedule K-1 box 13 code A page.
Column (e) is a percentage. “For each listed beneficiary, divide the amount shown in column (d) by the amount shown on line 1 and enter the result as a percentage.”
Line 3: more than 10 beneficiaries
“If you are allocating a payment of estimated taxes to more than 10 beneficiaries, list the additional beneficiaries on an attached sheet that follows the format of line 2.” “Enter on line 3 the total from the attached sheet(s).” Line 4 then adds the allocations, and the form says it “Must equal line 1”.
Where it goes next
Line 1 is carried “Enter here and on Form 1041, Schedule G, Part II,” and the instructions add “Be sure to include it on Form 1041, Schedule B, line 10.” On the Schedule K-1, the Form 1041 instructions say “If the fiduciary of a trust or decedent’s estate filed Form 1041-T, you must check this box and enter the date it was filed.” See the Schedule G Part II page for the payments section. The form, its deadline and how it is filed are on the Form 1041-T page.
Edition and line numbers
This page reads the Form 1041-T for 2025 and the Instructions for Form 1041 for 2025. They are the current files irs.gov served on 2026-10-18. The form is marked “Form 1041-T (2025)” and the Form 1041 instructions are marked “Instructions for Form 1041 (2025)”. Check the revision date printed on your own Form 1041-T and use that revision’s line numbers, because a different year’s form can word or number its lines differently.
Common mistakes
- Letting line 4 differ from line 1. The form says line 4 “Must equal line 1, above.”
- Listing beneficiaries out of order. The instructions say “First, list all the individual beneficiaries. Then, list all the other beneficiaries.”
- Allocating tax that was withheld. The instructions say “You can’t allocate to a beneficiary tax withheld from income”.
