Detailed answer
When renting a vehicle from the SeaTac Rental Car Facility (RCF), several distinct state, local, and airport-specific fees are legally integrated into the rental agreement. First, the standard Washington State retail sales tax is augmented by a 11.1% retail car rental tax, combined with an additional 10.0% King County rental car tax, which funds regional stadium and youth sports facilities. Second, the Port of Seattle imposes a 14.0% Airport Concession Recovery Fee (or concessionaire fee) on gross revenues to cover the operational rights at the airport terminal. Third, a mandatory Customer Facility Charge (CFC) of $7.00 per day is collected for all rentals up to a maximum of 5 consecutive days ($35.00 total per rental contract) to pay for the construction and debt service of the consolidated facility. Finally, if you utilize the commercial parking facilities at or near SeaTac, the City of SeaTac levies a Commercial Parking Tax of 10.0% on the parking fee, or a flat rate depending on the exact operator structure. These cumulative taxes and airport surcharges can add over 35% to the base rental rate, so travelers must carefully review their itemized rental agreements.
