Updated October 18, 2026. Quick answer: Lines 23 to 30 of Form 1041 turn the deductions into taxable income, bring in the total tax from Schedule G and the total payments, and settle the difference. Line 28 is tax due, line 29 is an overpayment, and line 30 says whether the overpayment is credited to next year or refunded.
IRS trust and estate tax forms, read line by line: Form 1041-ES, Form 1041-ES penalty and election and Schedule J Parts II and III.
What lines 23 to 30 do
The form’s captions are “Taxable income. Subtract line 22 from line 17.” for line 23, “Total tax (from Schedule G, Part I, line 9)” for line 24, “Total payments (from Schedule G, Part II, line 19)” for line 26 and “Estimated tax penalty.” for line 27.
Line 28 reads “Tax due. If line 26 is smaller than the total of lines 24, 25a, 25b, and 27, enter amount owed”. Line 29 is the reverse: “Overpayment. If line 26 is larger than the total of lines 24, 25a, 25b, and 27, enter amount overpaid”.
Line 23: taxable income
Line 23 takes the results of the lines 18 to 22 page and the lines 15a to 17 page. On a loss the instructions say “the estate or trust may have an NOL.” They add “Don’t include the deductions claimed on lines 13, 18, and 21 when figuring the amount of the NOL.” And on carrying a loss: “Complete Form 172, Net Operating Losses (NOLs), to figure the amount of the NOL that is available for carryback or carryover.”
Lines 24 and 26: tax and payments
Line 24 comes from Schedule G, Part I, which is walked through on the Schedule G Part I lines 1 to 3 and Schedule G Part I lines 4 to 9 pages, and the general bracket picture is on the trust tax brackets page. Line 26 comes from Schedule G, Part II, on the Schedule G Part II lines 10 to 19 page. Capital gains kept in a trust are covered on the capital gains in the trust page.
Line 27: estimated tax penalty
The instructions say “If line 28 is at least $1,000 and more than 10% of the tax shown on Form 1041, or the estate or trust underpaid its 2025 estimated tax liability for any payment period, it may owe a penalty.” “See Form 2210 to determine whether the estate or trust owes a penalty and to figure the amount of the penalty.”
Line 28: tax due and how to pay
The instructions say “You must pay the tax in full when the return is filed.” The due date itself is on the Form 1041 due date and extension page.
“The IRS recommends paying electronically whenever possible.” For a check: “Make the check payable to” “United States Treasury.” “Write the estate’s or trust’s name, EIN, and “2025 Form 1041″ on the check to assist us in posting it to the proper account.”
Lines 29 and 30: overpayment, credit or refund
For line 30a: “Enter the amount from line 29 that you want applied to the estate’s or trust’s 2026 estimated tax.”
For a refund: “If there is an overpayment on line 30b, complete lines 30c, 30d, and 30e to enter your account information.” The form shows line 30c as the routing number, line 30d as the type of account and line 30e as the account number.
Where the number comes from
Line 23 is arithmetic from page 1. Line 24 comes from Schedule G, Part I, and line 26 from Schedule G, Part II, which in turn come from the estate’s or trust’s tax computation and from payment records such as estimated tax payments. Lines 30c to 30e come from the bank’s own paperwork.
Where it goes next
After line 30 the form turns to signatures. It opens the signature block with “Under penalties of perjury, I declare that I have examined this return”. Schedules A, B and G, which feed these lines, are on the Schedule A, Schedule B lines 1 to 8 and Schedule G Part I lines 1 to 3 pages.
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
- Treating the balance as optional. The instructions say “You must pay the tax in full when the return is filed.”
- Subtracting the wrong deductions when figuring a loss. The instructions say “Don’t include the deductions claimed on lines 13, 18, and 21 when figuring the amount of the NOL.”
- Ignoring the penalty line. The instructions say “See Form 2210 to determine whether the estate or trust owes a penalty and to figure the amount of the penalty.”
