Ohio · Ohio Department of Taxation · Used for tax years 2024

Ohio Form IT/SD 2210 determines whether you owe an interest penalty for underpayment of 2024 tax and calculates the amount due. It includes calculations for individual, school district, trust, estate, and pass-through entity tax filers.

Who files this form

Use the 2024 Ohio IT/SD 2210 to determine whether you owe an interest penalty for underpaying tax and to calculate the penalty.

  • IT 1040, SD 100, SD 100E, IT 1041, and IT 4708 filers: Use page 2. Its tests may show that no penalty is due, including when your 2024 tax liability minus withholding is $500 or less.
  • IT 1140 and IT 4738 filers: Use page 3. Do not complete the form if your total adjusted qualifying amount or qualifying taxable income for either the current year or the previous year is $10,000 or less. You do not owe an interest penalty in that case.

Special rules may exempt qualifying farmers and fishermen from the penalty.

What you'll need

Have these returns and records available to complete the form:

  • Your applicable 2024 and 2023 Ohio tax returns, for current-year and previous-year tax liability. Page 4 identifies the return lines to use.
  • Records of 2024 estimated tax payments, including amounts and payment dates.
  • The amount of any 2023 credit carried forward toward 2024 taxes.
  • For page 2 filers, your tax withheld from compensation.
  • Information showing whether you timely filed the applicable 2023 return.
  • The names and identifying numbers requested on page 1, including the primary taxpayer’s SSN and, for a joint return, the spouse’s name and SSN. Entity, trust, and estate fields include the name, FEIN, and decedent’s SSN for estates.

How to file

  • IT 1040, SD 100, SD 100E, IT 1041, and IT 4708 filers: Enter the penalty from page 2, line 17, on page 1. Include pages 1 and 2 with your return.
  • IT 1140 and IT 4738 filers: Enter the penalty from page 3, line 14, on page 1. Include pages 1 and 3 with your return.

Use UPPERCASE letters when completing the form. The supplied text does not provide a mailing address or e-file directions.

Common mistakes

  • Using calendar-year dates and rates for a fiscal-year return. The form specifically requires fiscal-year filers to adjust both.
  • Leaving out the required pages. Include pages 1 and 2, or pages 1 and 3, with your return, depending on which return you file.
  • Overlooking the farming or fishing exception. The form highlights special rules for taxpayers who receive at least two-thirds of their gross income from farming or fishing.
  • Completing the form despite the page 3 exemption. IT 1140 and IT 4738 filers should not complete it when the specified qualifying amount or income for either year is $10,000 or less.

Questions people ask

Can I avoid a penalty by paying 90% of my 2024 tax liability?

Both calculation pages direct you to stop with no interest penalty if taxes paid on line 1 are at least 90% of your 2024 tax liability on line 2. Use the definitions for your applicable page to determine taxes paid and tax liability.

Does my 2023 tax liability matter?

Yes. If you timely filed the applicable 2023 Ohio return and line 1 taxes paid are at least your 2023 tax liability, the form directs you to stop because you have no interest penalty.

Can I combine individual and school district income tax when calculating the penalty?

Yes. The form says you may be able to reduce or eliminate the penalty by completing page 2 using your combined individual and school district income tax liability and total taxes paid.

How do fiscal-year filers calculate their rates?

Use your specific estimated-payment due dates. The printed formula is: interest rate × number of days the payment is late ÷ 365.25. The form states that the statutory interest rate is 8% for 2024 and 2025.
