General Instructions

Ohio personal income tax returns are due by the 15th day of the 4th month after the end of the tax year (usually April 15 for calendar year taxpayers). If you cannot file by this date, you can get an Ohio tax extension.

In order to get an Ohio personal extension, you must first obtain a Federal tax extension (IRS Form 4868). The State of Ohio recognizes a valid Federal extension and will automatically grant you a corresponding state extension  — there is no separate Ohio application form. Make sure to include a copy of your approved Federal extension with your Ohio tax return when it’s filed.

A tax extension only gives you more time to file, not to pay. To avoid interest and penalties, your Ohio income tax must be paid by the original deadline (April 15). You can make a state extension payment using Ohio Form IT 40P (Income Tax Payment Voucher), or by going online to the Ohio “ePayment” portal: www.tax.ohio.gov/online_services/ohio_epayment
