Estimated Payments

Should I make estimated payments for tax year 2021?

If your income is subject to Ohio withholding, meaning there is money taken out of your paycheck for Ohio withholding, you generally do not need to make estimated payments. You should make estimated payments if your estimated Ohio tax liability (total tax minus total credits) less Ohio withholding is more than $500.

Estimated payments are made quarterly according to the following schedule:

2021 Payment Due Dates:
1st Quarter -  April  15, 2021
2nd Quarter - June 15, 2021
3rd Quarter -  Sept. 15, 2021
4th Quarter -  Jan. 18, 2022

Use the Ohio IT 1040ES vouchers to make estimated Ohio income tax payments. Use the Ohio SD 100ES vouchers to make estimated Ohio school district tax payments. Joint filers should determine their combined estimated Ohio tax liability and make joint estimated payments.

If you estimate that you will owe more than $500 in tax for 2021 (after subtracting your estimated withholding and credits), then you should make quarterly estimated payments. Quarterly estimated payments can be made electronically. If paying by check or money order, use the Ohio IT 1040ES and/or SD 100ES payment vouchers using the correct year.

To assist taxpayers in determining their estimated payments, a complete set of tax rates is available.

TIP: Instead of making estimated payments, you may increase your Ohio withholding by filing a revised Ohio IT 4 (Employer Withholding Exemption Certificate) with your employer.

If you do not make the required estimated payments or increase your withholding, you may be subject to an interest penalty for underpayment of estimated taxes. See form IT/SD 2210.
