Taxpayers who discover an error after filing a federal tax return may need to file an amended return. There are some instances where an amended return isn’t required such as when the IRS corrects errors during processing or requests missing forms or schedules separately.
Reasons to file an amended returnIf there are changes to key items on the original return, including:
- Filing status
- Income
- Deductions
- Credits
- Dependents
- Tax liability
Taxpayers can use the "Should I File an amended return?" tool within the IRS Interactive Tax Assistant to help decide if they should file an amended return to correct an error or make other changes if they already filed.
