The Commonwealth of Massachusetts will grant your business a six-month tax extension if you submit the proper extension form (listed below) on time, along with any tax balance due. Filing for a Massachusetts tax extension will not provide you with additional time to pay any tax balance owed, which must be paid by your original filing deadline or interest and other payment penalties may apply.

For additional information, please visit the Commonwealth of Massachusetts Department of Revenue website.
