Drivers under 25 face a daily surcharge, and SeaTac locations include specific state taxes and facility-related surcharges.

## What to know

When renting a vehicle at the Seattle-Tacoma International Airport (SeaTac) facility, specific financial policies apply to certain demographics and programs. Drivers under the age of 25 are subject to a 'Young Driver Surcharge,' which typically ranges from $25.00 to $35.00 per day, depending on the vehicle category and rental agency. This fee is mandatory to offset higher insurance risks associated with inexperienced drivers. Additionally, frequent travelers utilizing certain loyalty programs may encounter daily administrative surcharges or processing fees if they do not meet specific tier requirements. Locally, the SeaTac location is subject to the Washington State Sales Tax, which is currently around 10.1% in the King County area. Furthermore, a mandatory Rental Car Charge (often exceeding $5.00 per day per vehicle) is applied to maintain the airport's rental car center infrastructure. Renters are encouraged to review their final agreement for these itemized taxes and surcharges to avoid unexpected costs at the rental counter.
