Updated October 18, 2026. Quick answer: Schedule B works out the income distribution deduction for Form 1041. Lines 1 to 8 build distributable net income, or DNI, starting from adjusted total income on page 1 and adjusting for tax-exempt interest and capital gains. Line 8 is accounting income, filled in only for a complex trust.
IRS trust and estate tax forms, read line by line: Schedule J (Form 1041), Schedule J Part I lines 1 to 5 and Schedule J Parts II and III.
What lines 1 to 8 do
The form’s captions are “Adjusted total income.” for line 1, “Adjusted tax-exempt interest” for line 2 and “Distributable net income. Combine lines 1 through 6.” for line 7. The instructions open with “If the estate or trust was required to distribute income currently or if it paid, credited, or was required to distribute any other amounts to beneficiaries during the tax year, complete Schedule B to determine the estate’s or trust’s income distribution deduction.” The concept is explained on the distribution deduction and DNI page.
Line 1: adjusted total income
The instructions say “Generally, enter on Schedule B, line 1, the amount from line 17 on page 1 of Form 1041.” For two losses: “if both line 4 and line 17 on page 1 of Form 1041 are losses, enter on Schedule B, line 1, the smaller of those losses.” And “If line 4 is zero or a gain and line 17 is a loss, enter zero on line 1 of Schedule B.”
Line 17 is explained on the lines 15a to 17 page.
Line 2: adjusted tax-exempt interest
The instructions give two steps. “Add tax-exempt interest income on line 2 of Schedule A, any expenses allowable under section 212 allocable to tax-exempt interest, and any interest expense allocable to tax-exempt interest.” Then “Subtract the Step 1 total from the amount of tax-exempt interest (including exempt-interest dividends) received.” Line 2 of Schedule A is the amount allocable to charitable contributions.
Lines 3 to 6: capital gains
Line 3 reads “Total net gain from Schedule D (Form 1041), line 19, column (1).” The instructions say “Include all capital gains, whether or not distributed, that are attributable to income under the governing instrument or local law.” and “If the amount in column (1) of Schedule D (Form 1041), line 19, is a net loss, enter zero.”
Line 4 reads “Enter amount from Schedule A, line 4 (minus any allocable section 1202 exclusion)”. Line 5 reads “Capital gains for the tax year included on Schedule A, line 1.” The instructions say “Reduce the amount on line 5 by any allocable section 1202 exclusion.”
Line 6 reads “Enter any gain from page 1, line 4, as a negative number.” and “If page 1, line 4, is a loss, enter the loss as a positive number”. See also capital gains in the trust.
Line 7: distributable net income
Line 7 is the total of lines 1 through 6 on the form’s own wording: “Distributable net income. Combine lines 1 through 6.” The form adds the rule for a result of zero or less, which is stated on the form beside the line.
Line 8: accounting income
The instructions say “If you are filing for a decedent’s estate or a simple trust, skip this line.” and “If you are filing for a complex trust, enter the income for the tax year determined under the terms of the governing instrument and applicable local law.”
Where the number comes from
Line 1 comes from page 1. Line 2 comes from the tax-exempt interest records and Schedule A. Lines 3 and 5 come from Schedule D and Schedule A, line 4 from Schedule A, and line 6 from page 1, line 4. Line 8 comes from the trust’s governing instrument and the accounting records the fiduciary keeps.
Where it goes next
Lines 9 to 15 take distributions and finish the deduction, covered on the Schedule B lines 9 to 15 page. Line 15 reads “Income distribution deduction. Enter the smaller of line 13 or line 14 here and on page 1, line 18”. The beneficiaries then receive Schedule K-1 amounts, and the return’s line 18 is on the lines 18 to 22 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
- Entering line 17 automatically when both it and line 4 are losses. The instructions say “enter on Schedule B, line 1, the smaller of those losses.”
- Reducing line 3 for a section 1202 exclusion. The instructions say “If the exclusion of gain from the sale or exchange of QSB stock was claimed, don’t reduce the gain on line 3 by any amount excluded under section 1202.”
- Filling in line 8 for an estate or simple trust. The instructions say “If you are filing for a decedent’s estate or a simple trust, skip this line.”
