Accounting & Tax Services in Seattle, WA
Seattle’s metro GDP exceeds $430 billion, making it one of the largest economies in the Pacific Northwest. The city’s tech corridor stretching from South Lake Union through the Eastside has attracted Amazon (75,000+ local employees), Microsoft, Meta, and Google, along with hundreds of AI startups and SaaS companies. With the highest concentration of STEM workers in the United States, Seattle business owners frequently manage complex equity compensation, stock option exercises, and multi-state tax implications.
Washington’s B&O tax applies to Seattle businesses based on gross receipts, with service businesses paying 1.5% and retailers paying 0.471%. The city’s position as the West Coast’s busiest port complex by container volume means many local businesses also manage multi-state sales tax obligations from nationwide shipping. Seattle’s biotech cluster around Fred Hutch and UW Medicine adds another layer of specialized accounting needs, including R&D tax credits and grant accounting.
SDO CPA works with Seattle business owners across technology, healthcare, and e-commerce to structure entities, optimize S-Corp reasonable compensation, and manage the interplay between federal tax obligations and Washington’s B&O tax. For startups in South Lake Union or established firms in Pioneer Square, we provide monthly bookkeeping and fractional CFO services scaled to your stage of growth.
Washington Tax Planning Tip
Washington has no state income tax, but the B&O (Business & Occupation) tax applies to gross receipts at rates varying by classification: 1.5% for service businesses, 0.471% for manufacturing, and 0.484% for retailing. Many Seattle businesses overpay because they file under the wrong classification or miss available credits. Proper classification review can reduce your B&O liability significantly.
