An Act relating to vehicle rental taxes; relating to the issuance of subpoenas related to tax records; and providing for an effective date.

SB 138 adjusts Alaska's passenger vehicle rental tax rates, imposing a 10% tax on traditional rentals (not arranged through a platform) and an 8% tax on rentals arranged through a vehicle rental platform (like apps or websites). It requires platforms with over 200 annual transactions to collect and pay the tax, provide tax records to the state, and exempts them from liability if they made reasonable efforts to obtain correct information from vehicle owners. The bill also prohibits the state from collecting taxes for platform rentals that occurred before the bill's effective date. This primarily affects rental companies and platforms meeting the transaction threshold, with no retroactive tax collection for prior platform transactions.
