Do I Need to File a Separate Tax Extension for Ohio If I Already Filed a Federal Tax Extension?

No, Ohio will honor your federal extension (IRS Form 4868).  No separate extension will be needed for the state. 

When you complete your Ohio IT 1040, you will simply need to check the box indicating you filed for a federal extension and include a copy of FORM 4868 or IRS acknowledgment and/or your extension confirmation number with your Ohio return. 

This will also extend the filing deadline for your school district as well (SD 100), if applicable.

When is the Deadline to File a Tax Extension for Ohio?

The deadline will align with your federal six-month extension of October 15th. Ohio will honor your federal tax extension deadline, and no further forms will need to be submitted. Remember that states have varying rules.

How Do I File an Ohio Tax Extension?

Ohio will grant you an Ohio state tax extension only if you have a federal tax extension. Check the box on your Ohio IT 1040 indicating you filed for a federal extension. No additional forms will be required at the state level. 

Do I Need to Pay My State Taxes When I File a Tax Extension for Ohio?

Yes, you must pay any estimated state taxes due by April 15th to avoid penalties and interest. You can pay online using Ohio Tax eService. If mailing a check, us the Ohio Universal Payment Coupon (OUPC) and include your SSN or FEIN with the tax year written in the memo line.

What Are the Penalties for Filing My Taxes Late in Ohio?

The penalty for filing your Ohio state taxes late is 5% of the tax due per month, up to a maximum of 50%. Filing an extension can help you avoid these penalties.

Example: If you owe $1,000 in Ohio state taxes and file your return three months late without an extension:

• 5% of $1,000 = $50 per month
• 3 months x $50 = $150

The penalty for three months late is $150.

What Are the Penalties for Paying My Taxes Late in Ohio?

Interest will also accrue on any unpaid taxes from the original due date of April 15th until you submit your payment. Ohio IT/SD Form 2210 provides more information on calculating interest.

In addition, you can check out the Ohio eServices Interest Calculator, which provides the most accurate information.

What are the Advantages of a Tax Extension in Ohio?

A tax extension gives you more time to gather documentation or complete your return accurately. In addition, pay your Ohio taxes by the original deadline to avoid penalties. Still unsure? A quick chat with a tax pro can help you get it right the first time.
