How Can I Amend my Massachusetts State Tax Return?
If you need to change a line item on your return, complete a new return with the corrected information and fill in the Amended return oval. Your amended return must include all schedules filed with the original return even if there are no changes to the schedules. Mail your amended return to the same address used for original returns. Do not file Form ABT with your amended return. An amended return can be filed to either increase or decrease your tax. An amended return should also be filed to correct a credit amount (such as withholding) or to dispute a health care penalty. Generally, an amended return must be filed within three years of the date that your original return was filed. Visit mass.gov/dor/amend for more information about filing an amended return.
