2210N: Individual Underpayment of Estimated Tax (2024)
Nebraska · Nebraska DOR · Used for tax years 2024
Nebraska Form 2210N calculates an individual's underpayment of estimated income tax and any resulting penalty for 2024. It compares required payments with estimated tax payments and withholding, and includes a separate calculation for farmers and ranchers. The form is attached to
Who files this form
Complete Form 2210N if your 2024 Nebraska income tax due, minus withholding and allowable credits, is $500 or more. The form determines whether you owe a penalty for underpaying estimated tax.
You do not owe a penalty if:
- Your 2024 tax after applicable credits and withholding is less than $500.
- You are a first-time Nebraska income tax filer.
- You had no Nebraska income tax liability for 2023, were a U.S. citizen or resident for the entire year, and your 2023 Nebraska return covered, or would have covered, a full 12 months.
The form also tells you to stop if your withholding on line 5 equals or exceeds the required annual payment on line 8.
Special rules apply if income from farming, ranching, or fishing was at least two-thirds of your total annual gross income for 2023 or 2024. If you meet that test, file Form 1040N, and pay the Nebraska income tax due by March 1, you do not owe a penalty and do not have to file Form 2210N.
When it's due
For tax year 2024, Form 2210N lists these estimated-tax installment due dates:
- April 15, 2024
- June 15, 2024
- September 15, 2024
- January 15, 2025
If you file your 2024 Nebraska return and pay the income tax due by January 31, 2025, you will not owe a penalty for the installment due January 15, 2025. Follow the form's instructions for entering that payment in the January 15 column.
For the special farming, ranching, or fishing exception on the 2024 form, the filing and payment deadline is March 1.
File Form 2210N with Form 1040N. Fiscal-year taxpayers must adjust the installment dates as directed in the form's instructions.
What you'll need
Have these returns and payment details available:
- Your 2024 Form 1040N, including tax, withholding, refundable credits, and the pass-through entity tax (PTET) credit.
- Your 2023 Form 1040N for the prior-year tax and credit calculation, plus your 2023 federal adjusted gross income.
- The amounts and dates of estimated-tax payments and any prior-year overpayment carried forward.
- Your 2023 school district property tax credit information. If using the Nebraska Property Tax Look-Up Tool, you will need the property's Parcel ID Number.
Paper filers must also attach a separate computation schedule if annualizing income, or a statement explaining why the penalty should not apply if requesting a waiver.
How to file
Attach Form 2210N to your Nebraska Individual Income Tax Return, Form 1040N, and file them together. The supplied text does not give a mailing address or detailed e-file submission steps.
- Complete lines 1 through 8 and follow any instructions to stop.
- For the regular installment calculation, complete lines 12 through 18 for one column before moving to the next. Calculate the penalty on lines 19 through 23.
- Farmers and ranchers using the special rules complete lines 24 through 33 as applicable.
- Enter the penalty from line 23 or line 33 on line 50 of Form 1040N.
If annualizing income, check the box at the top of Form 2210N. Paper filers must attach the required computation schedule. Paper filers requesting a waiver must attach an explanatory statement.
DOR encourages taxpayers to make estimated income tax payments electronically. That payment guidance is separate from the requirement to attach Form 2210N to the return.
Common mistakes
- Including estimated payments on line 5. This line is for withholding only.
- Assuming a refund means no penalty. A penalty can apply even when your return shows a refund. Each installment is calculated separately, so later payments may not eliminate an earlier penalty.
- Using the wrong carryover amount. DOR applies a prior-year overpayment to existing balances from other tax years first. Contact DOR if you are unsure of the amount available for current-year estimated payments.
- Assigning a payment to a later installment while an earlier one is unpaid. Payments are applied first to earlier underpayments, regardless of the period you designate.
- Filing Form 21 for the specified school district credit adjustment. If you include the school district property tax credit allowed on your 2023 return in line 2, the instructions say not to file a Request for Abatement of Penalty, Form 21.
Questions people ask
How is my required annual payment calculated?
Generally, line 8 uses the smaller of 90% of your 2024 tax after the credits used on the form or 100% of your 2023 tax, calculated under the line 7 instructions. The prior-year method requires a full 12-month tax year. If you were not engaged in farming, ranching, or fishing and your 2023 federal adjusted gross income exceeded $150,000, or $75,000 if married filing separately, line 7 uses 110% of your 2023 tax.
How is withholding divided among installments?
One-fourth of Nebraska income tax withheld by your employer during the year is treated as paid on each required installment date, unless you establish when the withholding actually occurred.
Can annualizing my income help?
No penalty is imposed if your payments equal or exceed 90% of your Nebraska tax liability based on annualized income earned through the end of the month before the installment date. Check the annualizing box if you meet this rule. Paper filers must attach a separate computation schedule similar to the federal Annualized Income Installment Method Schedule.
Can DOR waive the penalty?
DOR may consider a waiver for underpayment caused by casualty, disaster, or another unusual circumstance where imposing the penalty would be inequitable. It may also consider a waiver if, in 2023 or 2024, you retired after reaching age 62 or became disabled, and the underpayment was due to reasonable cause. Paper filers must attach a statement explaining why the penalty should not be imposed.
