federal return. When filing your amended returns, you must include: 
                           Option #1                                                                                                 Option #2

Tax Due: To reduce the amount of interest you will owe, you should file 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: property records (mortgage 
statements, lease agreements, etc.), driver's licenses or state IDs, voter registration, resident state tax returns, armed services records 
and utility bills.
What documentation should I include when amending to show a change to Ohio Schedule of Adjustments?
You should always include supporting documentation to substantiate your changes specific to the deduction. Some common deductions 
and related documentation include, but are not limited to, the following:
Business income – Ohio Schedule of Business Income, page 1 and 2 of your federal return, the federal schedule(s) showing your 
business income, federal K-1(s), wage and income statement(s), along with any other supporting documentation. Include a short state-
ment explaining your position on the amounts claimed as business income, along with all relevant facts and law used in making that 
determination.
Disability/survivorship benefits – A copy of your wages and income statements (such as 1099’s), page 1 and 2 of your federal return,  
and your disability/survivorship plan. If you are deducting disability benefits, you must also provide a letter from your employer from 
when your disability was approved, your social security disability award letter, and your age at the time of disability.
Unreimbursed medical and health care expenses – A copy of Ohio's medical expense worksheet, federal Schedule A (if completed), 
and proof of payments (cancelled checks, bank statements, credit card statements, etc.).
529 Plan Contributions – Proof of payments (cancelled checks, bank statements, credit card statements, etc.) and proof of an 529 ac-
count (by providing the plan year-end statement). If the statement is unavailable, (e.g. you are not the account holder), provide a list of 
the beneficiaries with the contribution dates and amounts. If the deduction is based on a prior year carryforward, provide proof of prior 
year contributions for each beneficiary.
What documentation should I include when amending to show a change to the nonresident or resident credit?
Nonresident credit: A copy of form IT NRC and all wage and income statements (W-2, 1099, K-1, etc.).
Resident credit: A copy of form IT RC, all other state returns and proof of taxes paid to other states (cancelled checks, transcripts).

When should I NOT file 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;                                                                                                      • Unclaimed estimated and/or extension payments;* 
• Missing return pages, schedules, or worksheets;                                                                   • Unclaimed withholding;**                                                
• Demographic errors (such as name, address or SSN                                                                  • Missing credit certificate granted by the Ohio Department  
corrections);                                                                                                         of Development.

*Generally, unclaimed estimated and/or extension payments will automatically be added to your original return when filed.
**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 filing an amended return.
