Each return is due by the 30th day after the period it covers. Source: Massachusetts Department of Revenue, checked September 26, 2026.

How to check a Massachusetts firm yourself

If a firm says it's a CPA practice, the Board of Public Accountancy lookup is where to confirm it. The Massachusetts business entity search shows whether the firm's legal entity exists and its status. A sole proprietor may not appear, which isn't a warning sign on its own. We can't match Massachusetts's records automatically, which is why most Massachusetts firms here show Not verified for a license or registration. It means unchecked, not failed, so run the search yourself on your shortlist.
