This online application allows taxpayers to pay the sales tax for a boat, snowmobile, recreational and/or all terrain vehicle registration through Electronic Funds Withdrawal, and receive an immediate confirmation receipt. This receipt can then be presented to the Massachusetts Environmental Police at the time of registration. You may access this website from the link provided below, or during business hours at one of our District Offices. 

Please Note: The ST-6 online application will not accept returns older than or equal to 12/1/2009. If you're filing a ST-6 or ST-6E for a boat, snowmobile, recreational and/or all terrain vehicle with a "Sale Date" or "Date first brought into Massachusetts" older than or equal to 12/1/2009, then you will need to use our paper Form ST-6/6E.
