- Complete the registration ATV, Boat, and Snowmobile Registration application.
- Collect the bill of sale (private seller purchases).
- Collect the dealer's certificate showing sales tax paid (dealer purchases).
- Prepare to pay the applicable fees (these vary depending upon your situation).
When registering at the Augusta office or in a town other than your own, remember to first pay your excise tax in the town where you live. Be sure you have a receipt that shows the excise tax has been paid, or your vessel cannot be registered at another location.
If your boat is exempt from tax, complete a tax exemption form and submit it with your other documents.
While boat insurance is not a registration requirement in Maine, it is strongly suggested that you look into purchasing a boat insurance policy.
