Free Massachusetts Boat Bill of Sale
The agency name alone stops most Massachusetts boat buyers mid-search: vessels title through the ENVIRONMENTAL POLICE (Office of Law Enforcement) — the RMV that processed your car has no role in the boat, though it takes the trailer under it on a separate RMV-1. Form HS-BT 105 carries both the registration and title work, the tax is the familiar 6.25% paid to the Department of Revenue, and even USCG-documented vessels that skip the state title still owe Massachusetts use tax. As in every two-desk state, itemizing the boat and trailer prices separately on the bill of sale keeps both transfers clean.
