Overview
Titling a boat costs a flat $75, separate from registration. If you're bringing a boat in from out of state and it's over 12 feet, you'll also need a $30 Aquatic Invasive Species permit before launching on any Oregon waterway - the fee that funds the boat inspection stations you'll pass at the state line. The calculator below totals registration, title, and the AIS permit for your situation.

Oregon boat registration FAQ
How much does it cost to register a boat in Oregon?
$8 plus $5.95 per foot of length, rounded up to the next foot, for a 2-year registration. A 20-foot boat runs $8 + (20 × $5.95) = $127. First-time Oregon titling adds a flat $75.
Do kayaks and canoes need to register in Oregon?
Non-motorized kayaks, canoes, and paddleboards don't need OSMB registration, though many launch sites require a separate Waterway Access Permit ($6 for a week, $20 for a year) that funds ramps and facilities. Add a motor and full motorboat registration applies.
Does my sailboat need to register even if it's just moored?
Yes, if it's 12 feet or longer - Oregon requires titling and registration for sailboats at that length regardless of whether the boat is actively sailed or sitting at a dock.
What's the Aquatic Invasive Species permit and do I need it?
It's a $30 permit required for out-of-state motorboats and sailboats over 12 feet before operating on any Oregon waterway, funding the boat inspection stations that check for invasive mussels and weeds at state lines. Oregon-registered boats don't need it separately.
When does my boat registration expire?
OSMB runs registrations on a 2-year cycle tied to a biennial calendar starting November 1, not the date you bought the boat - check your registration card for your specific expiration.
Is there sales tax on a boat purchase in Oregon?
No - the same rule as vehicles applies. Oregon has no general sales tax, so a boat purchase (private-party or dealer, used or new) isn't taxed at the point of sale.
