Form 1041 Schedule G Part I Lines 1 to 3: Tax, Credits (2025)

Updated October 18, 2026. Quick answer: Lines 1 to 3 of Schedule G start the tax computation: line 1 gathers the tax, line 2 gathers the credits, and line 3 subtracts the credits from the tax. The tax on line 1a is figured from the taxable income on page 1 of Form 1041 using the Tax Rate Schedule in the instructions or a schedule or worksheet the instructions point to. Credit amounts come from the attached credit forms.

Retirement forms read line by line: Form 4972 Part II and Form 4972 lines 18 to 30.

What lines 1 to 3 do

The form titles the schedule “Tax Computation and Payments” and the first part “Tax Computation”. Line 1 is the tax block, with lines 1a to 1e. Line 2 collects credits on lines 2a to 2e, and line 3 reads “Subtract line 2e from line 1e.” The next lines are on the Schedule G Part I lines 4 to 9 page.

Line 1a: tax on taxable income

The caption is “Tax on taxable income. See instructions”. The instructions say “figure the tax using the following Tax Rate Schedule and enter the tax on line 1a.” The Tax Rate Schedule is a table printed in the instructions and this page does not copy its brackets; the trust tax brackets page compares trust brackets with individual ones.

Two other routes exist. For a return with Schedule D: “Use Part V of Schedule D (Form 1041), or the Schedule D Tax Worksheet, whichever is applicable, to figure the estate’s or trust’s tax”. For qualified dividends without a Schedule D computation: “If you don’t have to complete Part I or II of Schedule D and the estate or trust has an amount entered on line 2b(2) of Form 1041 and any taxable income (line 23), then figure the estate’s or trust’s tax using the worksheet, later, and enter the tax on line 1a.” Capital gains in the trust are discussed on the capital gains that stay in the trust page.

Lines 1b to 1e: other entries and the total

Line 1b is captioned “Tax on lump-sum distributions. Attach Form 4972”. Line 1c is captioned “Alternative minimum tax (from Schedule I (Form 1041), line 54)”. The instructions say “Attach Schedule I (Form 1041) if any of the following apply.” One of the listed conditions is “The estate or trust must complete Schedule B.” and the instructions then say “Enter the amount from line 54 of Schedule I (Form 1041) on line 1c.”

For line 1d the instructions say “enter the amount from column (q) of Form 4255, Part I, line 3, on line 1d.” Line 1e is “Total. Add lines 1a through 1d”. The instructions add “If the amount from line 14 of Form 8978 is a positive amount, include it in the total reported on line 1e.”

Lines 2a to 2e: the credits

Line 2a is the foreign tax credit. The instructions say “Attach Form 1116, Foreign Tax Credit (Individual, Estate, or Trust), if you elect to claim credit for income or profits taxes paid or accrued to a foreign country or a U.S. territory.” “The estate or trust may claim credit for that part of the foreign taxes not allocable to the beneficiaries (including charitable beneficiaries).”

Line 2b is the general business credit: “Don’t include any amounts that are allocated to a beneficiary.” “Enter on line 2b the estate’s or trust’s total general business credit allowed for the current year from Form 3800.”

Line 2c is the credit for prior year minimum tax: “An estate or trust that paid AMT in a previous year may be eligible for a minimum tax credit in 2025.” Line 2d covers bond credits: “Complete and attach Form 8912, Credit to Holders of Tax Credit Bonds, if the estate or trust claims a credit for holding a tax credit bond.”

Line 2e is the total: “include the allowable credit in the total for line 2e.” Also “If the amount from line 14 of Form 8978 is a negative amount, treat it as a positive amount and add it to the total reported on line 2e.”

Where the number comes from

The starting point for line 1a is the taxable income worked out on page 1, which is covered on the lines 23 to 30 page. The credit lines come from the credit forms named in the captions: Forms 1116, 3800, 8801 and 8912. The distribution deduction and exemption that reduce that taxable income are on the lines 18 to 22 page.

Where it goes next

Line 3 carries forward into the rest of the schedule. The next lines add the ESBT tax, the net investment income tax, recapture taxes and other amounts, and line 9 totals them. That is explained on the Schedule G Part I lines 4 to 9 page.

Edition and line numbers

This page reads Form 1041 (2025) and the 2025 Instructions for Form 1041 and Schedules A, B, G, J, and K-1. Those are the current files irs.gov served on 2026-10-18, byte-identical to the archived copies. The form reads “For calendar year 2025 or fiscal year beginning” and the instructions carry the title “Instructions for Form 1041 (2025)”. Check the year printed on your own Form 1041 and use the line numbers on that year’s form.

Common mistakes

  • Using the wrong route for the tax on line 1a. The instructions name three: the Tax Rate Schedule, the Schedule D computation, and the Qualified Dividends Tax Worksheet, and say “Use Part V of Schedule D (Form 1041), or the Schedule D Tax Worksheet, whichever is applicable, to figure the estate’s or trust’s tax”
  • Entering a credit that belongs to a beneficiary on line 2b. The instructions say “Don’t include any amounts that are allocated to a beneficiary.”
  • Claiming the foreign tax credit without the form. The instructions say “Attach Form 1116, Foreign Tax Credit (Individual, Estate, or Trust), if you elect to claim credit for income or profits taxes paid or accrued to a foreign country or a U.S. territory.”
