Form 38-ES — Fiduciary Estimated Income Tax

preamble

Who must pay estimated tax A fiduciary for an estate or trust must pay estimated North Dakota income tax for the 2026 tax year if all four of the following conditions apply: 1. The fiduciary is required to pa y estimated federal income tax for the 2026 tax year. This condition applies whether or not the fiduciary actually makes the required payment(s) of estimated tax to the Internal Revenue Service. 2. The fiduciary' s net tax liability for the 2025 tax year was equal to or more than $1,000. Note: If the fiduciary was not required to file a North Dakota income tax return for the 2025 tax year, the fiduciary's net tax liability is zero for purposes of this condition. 3. The fiduciary expects to owe (after subtracting any estimated North Dakota income tax withholding) an amount equal to or more than $1,000 for the 2026 tax year. 4. The fiduciary expects North Dak ota income tax withholding for the 2026 tax year to be less than the smaller of: a. 90% of the net tax liabilit y for the 2026 tax year. Note: Substitute 66 2/3% if a qualified farmer. See "Farmer" under "Payment amounts and due dates" later in these instructions. b . 100% of the net tax liabilit y for the 2025 tax year. Note: If the estate or trust was not in existence for the entire 2025 tax year, part b does not apply; the 90% threshold in part a must be applied. How to determine the estimated tax Complete the worksheet on page 2. For line 1 of the worksheet, estimate the federal taxable income using the 2026 Form 1041-ES, the federal estimated tax form for estates and trusts. For lines 2, 4, and 7 of the worksheet, see the instructions to the 2025 Form 38. Payment amounts and due dates In general, one-fourth (25%) of the total estimated tax required to be paid (from line 14 of the worksheet) for the 2026 tax year must be paid by each of the following due dates:  1st installment April 15, 2026  2nd installment June 15, 2026  3rd installment September 15, 2026  4th installment January 15, 2027 The above due dates apply if the fiduciary's tax year is a calendar year-January 1 through December 31, 2026. However, if the tax year is a fiscal year, the installments are due on the 15th day of the 4th, 6th, and 9th months of the current tax year, and the 15th day of the 1st month of the following tax year. If any installment due date falls on a Saturday, Sunday, or legal holiday, the installment is not due until the next business day. Farmer- If the fiduciary qualifies as a farmer for federal estimated income tax purposes for the 2026 tax year, the fiduciary may pay the estimated tax according to the general rules explained above, or the fiduciary may pay the full amount of the estimated tax due by January 15, 2027. Note: Regardless of the option chosen, the fiduciary has until the regular due date to file the 2026 North Dakota fiduciary income tax return. Part-year requirement-If a fiduciary for a nonresident estate or trust, or an estate or trust that was created during the tax year, does not receive income from North Dakota sources until after the first installment due date, the fiduciary must pay the required estimated tax in equal payments over the remaining installment due dates following the receipt of income from North Dakota sources. How and where to pay Electronic payment. Instead of paying by check or money order with this payment voucher, payment may be made electronically with an electronic check, a debit or credit card, or an Automated Clearing House (ACH) transaction. To pay electronically, go to www.tax.nd.gov and select "Make A Payment." If paying electronically, do not use the payment vouchers attached to this form. Payment by check or money order. If paying by check or money order, make it payable to "ND State Tax Commissioner." To ensure proper credit to the account, write the last four digits of the federal employer identification number (FEIN) and "2026 38-ES" on the check or money order. Detach and complete the applicable installment's payment voucher. Mail the payment and voucher to: Office of State T ax Commissioner 600 E. Boulev ard Ave., Dept. 127 Bismarck, ND 58505 - 0599 A check must be drawn on a U.S. or Canadian bank, be in U.S. dollars, and use a standard 9-digit routing number. A check drawn on a foreign bank (except one in Canada) cannot be accepted. Underpayment or late payment interest Interest may be charged if not enough estimated tax is paid, or if the payment is not made on time or in the required amount. This applies even if there is a refund on the North Dakota fiduciary income tax return for the 2026 tax year. Interest is calculated at the rate of 12% per year from the installment due date to the earlier of the date the estimated tax is paid or the regular due date of the return. Need help?
