Need to amend your tax return? Want to dispute a tax bill, penalty, or audit finding? Most taxpayers can do both online! It’s fast, simple and secure.

Individuals: go to DOR’s WebFile for Income application.

Taxpayers filing IFTA, Alcoholic Beverages, Ferry Embarkation Fee, or non-resident motor vehicle excise: go to MassTaxConnect.

Most other businesses filing withholding, sales, meals, or rooms occupancy tax: go to DOR's WebFile for Business
