Do I have to make Ohio estimated tax payments?
Ohio requires estimated payments once you expect to owe $500 or more in state income tax for the year. The state form is Form IT 1040ES. Payments can be made online through OH|TAX eServices. Filing and paying federal estimated tax does not cover the state amount — they are separate payments.
Where do I pay Ohio estimated taxes online?
Ohio accepts online estimated tax payments through OH|TAX eServices, run by the Ohio Department of Taxation. Federal payments go through IRS Direct Pay or EFTPS separately.
What happens if I underpay estimated taxes in Ohio?
The IRS charges an underpayment penalty based on the amount underpaid and the number of days late. Paying at least 90% of this year's tax or 100% of last year's (110% if your AGI exceeded $150,000) meets the federal safe harbour. Ohio applies its own interest and penalty on late or short state payments.
State payments are administered by the Ohio Department of Taxation via OH|TAX eServices.
