## What to know

When renting a car at the SeaTac Rental Car Facility, you may encounter additional fees beyond the base rate. These fees include airport concession fees, Washington state rental taxes, and additional driver/under-25 fees. The airport concession fee is a 6% tax on the base rental rate, which is currently $3.50 per day for a standard rental period. Washington state rental taxes are 6.5% of the base rental rate, which is currently $4.15 per day for a standard rental period. Additionally, there may be a fee for additional drivers or drivers under the age of 25, which can range from $13 to $27 per day, depending on the rental agency and the driver's age. These fees can add up quickly, so it's essential to factor them into your budget when renting a car at the SeaTac Rental Car Facility. For example, if you rent a car for 7 days with a base rate of $40 per day, the total cost would be $280, plus $3.50 per day in airport concession fees ($24.50), plus $4.15 per day in Washington state rental taxes ($29.05), and potentially $13 to $27 per day in additional driver/under-25 fees ($91 to $189). This brings the total cost to $424.55 to $504.55, depending on the fees applied.
