Amended IT 1040 Filing Tips
When amending due to changes to my federal return, should I le my amended Ohio return(s) at the same time I le my
amended federal return with the IRS?
Refund: You should wait to le your amended Ohio IT 1040 and/or SD 100 until the IRS has approved the changes to your
amended federal return. When ling your amended returns, you must include:
Option #1
• A copy of your federal amended return (1040X), AND
• A copy of the IRS acceptance letter -or- refund check.
Option #2
• A copy of your updated IRS account transcript reecting
the changes to your federal return.
Tax Due: To reduce the amount of interest you will owe, you should le your amended Ohio IT 1040 and pay any tax due as soon
as possible.
What documentation should I include when amending to show a change in my Ohio residency status?
Submit any and all relevant information you believe supports your change in residency status from one state to another. Provide
as many relevant documents as possible. Relevant documents include, but are not limited to, the following: driver's license or
state IDs, property records, voter registration, resident state tax returns, and vehicle registrations.
When should I NOT le an amended return?
Some common mistakes may not require an amended return. Instead, the Department of Taxation will either make the corrections
or contact you to request documentation. For example, the following mistakes generally do not require an amended return:
• Math errors;
• Missing return pages, schedules, or worksheets;
• Unclaimed withholding;**
• Missing credit certcate granted by the Ohio Development
*Generally, unclaimed estimated and/or extension payments will automatically be added to your original return when led.
**If you have unclaimed withholding, please submit a detailed explanation along with legible copies of all income statements
(W-2s and 1099s) showing the Ohio withholding amounts instead of ling an amended return.
For additional information, you can go to tax.ohio.gov for FAQs (located under the "Income - Amended Returns" topic).
• Demographic errors (such as name, address or SSN
corrections); Services Agency.
• Unclaimed estimated and/or extension payments;*
