File an Ohio Tax Return Amendment
Need to Correct an Error?
If you discover an error on your previously filed Ohio return, use Form IT-1040 to file an amended return. This applies for both the 2023 and past tax years. However, note that Form IT-1040 is specific to Ohio and cannot be used for federal tax amendments. For federal errors, please refer to IRS Form 1040X.
IRS Adjusted Your Federal Return?
The IRS will automatically notify the Ohio Department of Taxation if adjustments are made to your federal return. In this case, you have one year to file an amended Ohio return using Form IT-1040 to ensure your state taxes are accurate.
Changing Your Filing Status (Married Filers Only)
An amended return allows married filers to change their filing status from "married filing separately" to "married filing jointly." However, changing from "married filing jointly" to "married filing separately" is not permitted through an amended return.
Additional Considerations
While eFile.com can assist in preparing your amended Ohio return, it cannot electronically submit the amendment. You will need to mail the completed form to the Ohio Department of Taxation.
