Do I have to pay estimated tax in 2019?
Estimated tax is a method used to pay tax on income when your withholding and credits do not cover your tax liability. You should make estimated payments for tax year 2019 if your estimated Ohio tax liability (total tax minus total credits) less Ohio withholding is more than $500.
2019 Payment Due Dates:
1st Quarter - April 15, 2019
2nd Quarter - June 17, 2019
3rd Quarter - Sept. 16, 2019
4th Quarter - Jan. 15, 2020
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 2018 (after subtracting your estimated withholding and credits), then you should make quarterly estimated payments. Quarterly estimated payments can be made electronically on our Web site at tax.ohio.gov. Or you can obtain payment vouchers for Ohio IT 1040ES or SD 100ES from our Web site at tax.ohio.gov.
To assist taxpayers in determining their estimated payments, a complete set of tax rates through 2019 is available on this Web site.
TIP: If you don't want to make estimated payments, you may increase the amount of Ohio tax your employer withholds from your wages. To do this, file with your employer a revised Ohio form IT 4 (Employer Withholding Exemption Certificate).
If you do not make the required estimated payments, you may be subject to an interest penalty for underpayment of estimated taxes. See form IT/SD 2210.
