8-014-2025 Rev. 11-2025 If your Nebraska individual income tax, after allowance of Nebraska personal exemption credits, is expected to exceed withholding and other credits by $500 or more, then estimated income tax payments may be required. Various indexed values for the Nebraska personal exemption credit, Nebraska standard deduction, and other elements of the Nebraska tax calculation are included in this year's changes. You should calculate your estimated tax for 2026 in light of these changes. Taxpayers must ensure that adequate and timely estimated payments are made to avoid underpayment of estimated income tax penalties. 2026 Nebraska Individual Estimated Income Tax Payment Vouchers Included in this Booklet: Form 1040N-ES Electronic payment options are available.

Instructions Who Must Make Estimated Income Tax Payments. Every resident and nonresident must make estimated income tax payments if their Nebraska income tax, after Nebraska personal exemption credits, is expected to exceed their income tax withholding and other credits by $500 or more. If you are an employee with income tax being withheld from your earnings, you may ask your employer to withhold an additional amount for state income taxes, rather than make these four estimated income tax payments. When to Pay Your Estimated Income Tax. The first payment must be made on or before April 15, 2026, and on later dates as set out below. The estimated tax may be paid in full with the first payment, or in equal installments on or before April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. If the due date falls on a Saturday, Sunday, or legal holiday, taxpayers have until the next business day to make the payment.

• Farmers and Ranchers. If at least two-thirds of your gross income for 2025 or 2026 is derived from farming, ranching, or fishing, you may pay all of your estimated income tax on or before January 15, 2027 and still avoid a penalty for underpayment of estimated income tax. If you file your 2026 Nebraska Individual Income Tax Return, Form 1040N, on or before March 1, 2027, and pay the total income tax due at that time, you do not need to make any estimated income tax payments for 2026.

• Fiscal Year Taxpayers. Fiscal year taxpayers must pay their estimated income tax by the 15th day of the fourth, sixth, and ninth months of the fiscal year, and the first month of the following fiscal year. If the due date falls on a Saturday, Sunday, or legal holiday, taxpayers have until the next business day to make the payment. Distributors and Operators of Cash Devices. In addition to the estimated payment requirements indicated above, effective July 19, 2024, distributors and operators of cash devices must make quarterly income tax payments. This is also separate from the Net Operating Revenue tax that is due quarterly on each individual device. The income tax payments are due January 1st, April 1st, June 1st, and October 1st of each year. The quarterly income tax payments for distributors are based on the distributor’s income tax liability. The quarterly income tax payments for operators are based on the income generated by each cash device. Distributors and operators that are individuals (sole proprietorships or disregarded entities) may submit these payments with a Form 1040N-ES. If you submit both an estimated income tax payment and the quarterly income tax payment together, mark all applicable boxes (Estimated Payment, Payment by Distributor of Cash Device, and Payment by Operator of Cash Device) on the payment voucher. How to Calculate Your Estimated Income Tax Payment. Complete the Estimated Income Tax Worksheet (Worksheet) to compute your 2026 estimated income tax. If line 18 is less than $500, estimated income tax payments are not required, but may still be made. Subtract the amount of any carryover from the 2025 Form 1040N before making your payment. Make appropriate entries in your Record of Estimated Tax Payments. Changes in Estimated Income Tax. If your income increases during the year, you may be required to begin making estimated income tax payments, or increase the amount of your estimated income tax payments at the next due date. If you need to increase the amount of an estimated income tax payment and you have previously scheduled an electronic payment, be sure to cancel and reschedule your payment. You may use the Amended Computation Schedule on page 5 to calculate your amended estimated income tax if your income substantially increases. When making payment by paper check, show the amended estimated income tax on line 1 of the next payment voucher filed. If making payments electronically, do not file a voucher to show the change. How to Pay Your Estimated Income Tax. The Nebraska Department of Revenue (DOR) encourages you to pay electronically. When paying electronically, vouchers are not required. If you are not making electronic payments of estimated income tax, you can download the payment vouchers from our website. Electronic Payment Options Electronic Funds Withdrawal (EFW). With this payment option, you provide your payment information within your electronically-filed return. Your payment will automatically be withdrawn from your bank account on the date you specify. Nebraska e-pay. Nebraska e-pay is DOR’s web-based electronic payment system. You enter your payment and bank account information, and choose a date (up to a year in advance) to have your account debited. You will receive an email confirmation for each payment scheduled. Credit Card. Secure credit card payments can be initiated through ACI Payments, Inc. at acipayonline.com or via phone at 800-272-9829. Eligible credit cards include American Express, Discover, MasterCard, and VISA. A convenience fee will be charged to the card used. This fee is paid to the credit card vendor, not the State of Nebraska, and will appear on your credit card statement separately from the tax payment. At the end of your transaction, you will be given a confirmation number. Keep this number for your records. [If you are making your credit card payment by phone, you will need to provide the Nebraska Jurisdiction Code, which is 3700.] 2

Check or Money Order Using the Estimated Income Tax Payment Voucher. If you are not using one of the electronic payment options described above, include a check or money order payable to the “Nebraska Department of Revenue.” Checks written to DOR may be presented for payment electronically. You must enter your Social Security number (SSN) and your spouse’s SSN, if applicable, on the payment vouchers where indicated. List the names and SSNs in the same order on the voucher as you list them on your married, filing jointly return. Overpayment Credit From 2025. If you had an overpayment on your 2025 Form 1040N, and elected to apply it to your 2026 estimated income tax, the amount of that overpayment may be applied in full, or in part, to any installment. Taxpayers claiming an overpayment from line 54 of last year’s individual income tax return, Form 1040N, should be aware that an overpayment will be applied first to offset any existing balance due from another tax year. If DOR transfers all or part of an amount requested to be carried over to next year’s estimated income tax payments (current year carryover), a written notice of the offset will be issued. Please contact DOR if you are unsure of your current year carryover amount. Joint Payments. Payments of estimated income tax may be made on a married, filing jointly basis for Nebraska income tax purposes. Married, filing jointly payments may not be made if the spouses are separated under a decree of either divorce or separate maintenance, or if they have different taxable years. If married, filing jointly payments are made, but a married, filing jointly return is not filed for the taxable year, the estimated income tax paid for the year may be divided between spouses. Penalty For Not Paying Enough Estimated Income Tax. A penalty is imposed for underpayment of estimated income tax installments. The penalty is not due if you qualify for any of the exceptions listed on the Individual Underpayment of Estimated Tax, Form 2210N. Each individual who has underpaid estimated income tax must file a Form 2210N with the Form 1040N. The estimated tax is underpaid if the payments (including income tax withholding) are not equal to at least:

1. 90% (66 ⅔% for those engaged in farming, ranching, and fishing) of the income tax liability for the year, after reduction by credits other than income tax withholding or estimated income tax payments;

2. 100% of the income tax shown on the Nebraska return for the full 12‑month preceding tax year, if federal AGI was $150,000 or less; or

3. 110% (the applicable federal percentage) of the preceding year’s income tax reported on a Nebraska return, if 2025 federal AGI was above $150,000. Complete the Nebraska Individual Estimated Income Tax Worksheet on page 4. You may also owe a penalty if estimated income tax payments are not filed in a timely manner. Exceptions to the Penalty. You do not have to pay the penalty if:

1. You had no income tax liability for 2025, you were a U.S. citizen or resident for the entire year, and your 2025 Nebraska income tax return was (or would have been had you been required to file) for a full 12 months;

2. You are a first-time filer for Nebraska income tax purposes; or

3. The total income tax shown on your 2026 Nebraska income tax return minus the amount of income tax you paid through income tax withholding is less than $500. 3
