# The Hidden Taxes of Seattle Car Rentals Explained

Renting a car at Seattle-Tacoma International Airport can be a straightforward process, but the final bill often comes with surprises. As an experienced logistics coordinator, I've seen firsthand how 'shuttle math' and opaque fees can frustrate travelers. Let's break down the hidden taxes and fees associated with car rentals at SeaTac.

Uncovering the Customer Facility Charge (CFC)

The CFC is a daily fee that funds the construction and maintenance of the rental car facility. At SeaTac, this fee is $6.50 per day, with a maximum of $30 per rental period. This charge is usually passed on to the customer, but it's not always clearly disclosed. Check our [directions](/directions) to the rental car facility to understand the layout and associated costs.

Rental Car Taxes and Fees: What's Included?

Washington state sales tax is 6.5%, and King County adds another 0.5% to 3.6%, depending on the location. Additionally, there's a Rental Car Facility Charge (RCFC) of $6.00 per day. Some rental agencies may also charge an 'administrative fee' or 'recovery fee' that can add to the overall cost. Compare rates among different [agencies](/agencies) to find the best deal.

Tips for Minimizing Hidden Fees

1. Choose a rental agency with transparent pricing: Look for agencies that clearly disclose all fees and taxes upfront.

2. Consider off-airport rentals: Renting from an off-airport location can save you the CFC and RCFC.

3. Use a travel rewards credit card: Some credit cards offer rental car insurance, gas reimbursements, or other perks that can offset additional fees.
