SeaTac’s 2026 hospitality and transportation minimum wage is $20.74/hour
SeaTac’s average daily population is 209,381, far above its resident population
SeaTac Small Business by the Numbers
SeaTac’s local economy is larger than its resident population suggests. That is because the city serves airport travelers, hotel guests, transportation firms, food service businesses, and logistics companies every day.
SeaTac businesses often handle more operational complexity than a typical small business. Hotels, restaurants, airport-adjacent service firms, transportation companies, and logistics providers deal with high transaction volume, shift payroll, vendor payments, and heavy card activity.
That matters in Washington because the state B&O tax is based on gross receipts, not net income. It also matters in SeaTac because local rules around business licensing and employment standards can affect payroll setup and compliance. Clean books make it easier to stay ready for tax filings, payroll reporting, and year-end work with your CPA.
