Schedule G Form 1041: Tax Computation, Credits, and Add-Backs

Schedule G of Form 1041 is where the fiduciary of an estate or trust computes the entity’s total tax. The computation starts with taxable income from Line 23 of Form 1041, applies the compressed trust and estate rate schedule (or preferential rates for capital gains and qualified dividends), subtracts allowable credits, then adds the alternative minimum tax, the net investment income tax, ESBT tax, and various recapture items. The result on Line 9 carries directly to Line 24 on page one of Form 1041 as the entity’s tax bill.¹

The Rate Schedule That Drives Everything

Before working through the lines, understand the rate structure, because it explains why every choice on this schedule matters. Estates and trusts hit the top 37% bracket at just $16,000 of taxable income for 2026:²

10% on taxable income up to $3,300
24% on taxable income from $3,300 to $11,700
35% on taxable income from $11,700 to $16,000
37% on taxable income over $16,000

There is no 12%, 22%, or 32% bracket. The rate jumps from 10% straight to 24%, then to 35% and 37%.³ A trust retaining $20,000 in ordinary income for 2026 owes $5,331; a single individual filer with the same $20,000 of taxable income owes $2,138. That gap is why fiduciaries push income out to beneficiaries whenever the governing instrument allows it.

Line 1a Through 1e: Computing the Base Tax

Line 1a starts with taxable income from Line 23 of Form 1041 (not Line 22, which is total deductions).¹ Apply the bracket schedule above to that amount and enter the result. This is the tax on ordinary income: interest, rents, royalties, business income, and anything else not eligible for preferential rates.

Capital Gains and Qualified Dividends

If the entity has net long-term capital gain or qualified dividends, do not use the straight bracket calculation. Those amounts are taxed at 0%, 15%, or 20%, and the computation runs through the Schedule D Tax Worksheet or the Qualified Dividends Tax Worksheet. The worksheet output replaces the plain rate-schedule figure on Line 1a.⁴ The preferential-rate thresholds are compressed for trusts and estates the same way ordinary brackets are; for 2025 the 20% capital gains rate began once taxable income exceeded $15,900, with a small inflation adjustment for 2026.⁵

Lines 1b Through 1d

These lines pick up less common items:

Line 1b, lump-sum distributions from Form 4972. This applies only to plan participants born before January 2, 1936, so it rarely appears on new estates.⁶
Line 1c, alternative minimum tax from Schedule I (Form 1041), Line 54. The AMT exemption for estates and trusts is $31,400 for 2026; entities with alternative minimum taxable income below that owe no AMT.⁷
Line 1d, investment credit recapture from Form 4255, when property that generated an investment credit was disposed of.

Line 1e is the sum of 1a through 1d. That is the entity’s gross tax before credits.

Lines 2a Through 2e and Line 3: Subtracting Credits

Credits cut the tax bill dollar for dollar. Schedule G lists four specifically and totals them:

Line 2a, foreign tax credit from Form 1116, for income tax paid to a foreign country.
Line 2b, general business credit from Form 3800.
Line 2c, credit for prior-year minimum tax from Form 8801, when the entity paid AMT in a prior year.
Line 2d, bond credits from Form 8912.

Line 2e totals lines 2a through 2d, and any other allowable credit not specifically listed gets folded into that total.⁴ Line 3 subtracts Line 2e from Line 1e; if credits exceed the gross tax, Line 3 is zero.

Lines 4 Through 8: Taxes Added Back

New fiduciaries often assume the computation ends after credits. It does not. Several special taxes get layered on top of Line 3.

Line 4, ESBT Tax

An Electing Small Business Trust holding S corporation stock computes tax on the S corporation portion separately, using the ESBT Tax Worksheet. That portion is taxed at the highest individual rate, 37% for 2026, on essentially every dollar, with no graduated brackets, because S corporation income flowing to an ESBT is walled off from the trust’s other income.⁴

Line 5, Net Investment Income Tax

This is the line most commonly missed. Estates and trusts owe a 3.8% surtax on the lesser of undistributed net investment income or the amount by which adjusted gross income exceeds the threshold for the top bracket.⁸ For 2026 that threshold is $16,000, the same amount that triggers the 37% bracket.² Net investment income includes interest, dividends, capital gains, rents, royalties, and passive business income. Because the threshold is so low, most trusts and estates with retained investment income owe something on this line. Compute the amount on Form 8960.

Lines 6a, 6b, and 6c, Recapture Taxes

Line 6a captures additional investment credit recapture from Form 4255. Line 6b handles low-income housing credit recapture from Form 8611, triggered when the entity disposes of or reduces its interest in a qualified project. Line 6c is a catch-all for other recapture, including the new markets credit and the qualified electric vehicle credit.

Line 7, Household Employment Taxes

If the estate or trust employs household workers, Schedule H tax lands here.

Line 8, Miscellaneous

Interest on installment sale obligations of certain large property, look-back interest under the income forecast method, and excise taxes on missed required minimum distributions from retirement accounts all appear on this line.⁴

Line 9: The Total and Where It Goes

Line 9 adds Lines 3 through 8. That figure carries to Line 24 on page one of Form 1041.¹ From there, Form 1041 subtracts payments to produce the balance due or refund. Those payments are entered in Schedule G Part II: Line 10 for estimated tax payments made with Form 1041-ES plus any overpayment applied from the prior year, Line 13 for amounts paid with a Form 7004 extension request, and Line 14 for federal income tax withheld, such as backup withholding on interest or dividends.

A Worked Example

A trust retains $25,000 of ordinary taxable income for 2026 after distributions and deductions. No capital gains, no AMT, no credits.

Line 1a, applying the 2026 rate schedule:

10% on the first $3,300 = $330
24% on the next $8,400 (from $3,300 to $11,700) = $2,016
35% on the next $4,300 (from $11,700 to $16,000) = $1,505
37% on the remaining $9,000 (from $16,000 to $25,000) = $3,330
Line 1a total: $7,181

Lines 1b through 1d are zero, so Line 1e is $7,181. No credits, so Line 3 is also $7,181. No ESBT income, household employees, or recapture. But the trust does owe NIIT: AGI of $25,000 exceeds the $16,000 threshold by $9,000, and all $25,000 is undistributed net investment income, so the surtax on Line 5 is 3.8% of $9,000, or $342. Line 9 totals $7,523, an effective rate of about 30.1%.

When Schedule G Does Not Apply

A grantor trust does not run its tax computation through Schedule G. The income, deductions, and credits are reported on the grantor’s personal return, and the fiduciary files Form 1041 only for entity identification, attaching a statement instead of computing tax on the schedule.⁹

For entities that do file a full return, a domestic estate must file when gross income reaches $600 or when any beneficiary is a nonresident alien. A domestic trust must file whenever it has any taxable income at all, or when gross income reaches $600.⁴¹⁰⁹

Why the Distribution Decision Shapes the Whole Schedule

Every line on Schedule G traces back to how much income the fiduciary distributed versus retained. Retained ordinary income crosses the 37% threshold at $16,000, and the 3.8% NIIT stacks on top of that, pushing the marginal rate on retained investment income above $16,000 to 40.8% at the entity level. A beneficiary in the 22% bracket would owe roughly half as much on the same income.

The distribution deduction on Form 1041 is capped by distributable net income, which is broadly the entity’s taxable income with capital gains generally excluded (unless allocated to income under the trust instrument or local law) and tax-exempt interest excluded. Estates and certain trusts can also elect under Section 663(b) to treat distributions made within 65 days after year-end as if they were made on the last day of the prior tax year, preserving the current-year deduction.¹⁰ The distribution choice is where the real tax planning happens. Schedule G just tallies what that choice produced.
