Accounting & Tax Services in Renton, WA
Renton is home to Boeing’s 737 assembly line, the company’s highest-volume commercial aircraft production facility, employing thousands of workers at the plant along the south shore of Lake Washington. The city has also attracted major technology companies, with multiple tech firms establishing offices in The Landing and along Rainier Avenue, drawn by proximity to both Seattle and the Eastside tech corridor. Providence Health’s Valley Medical Center and UW Medicine clinics serve the south King County population, supporting a network of specialty practices and medical billing operations. Renton’s diverse economy spans aerospace manufacturing, software development, healthcare services, and a growing retail sector anchored by The Landing shopping center and Renton Center. The Renton Highlands and Benson Hill neighborhoods have seen significant residential development, with many new residents commuting to tech jobs in Seattle and Bellevue while operating side businesses locally. SDO CPA serves Renton business owners across aerospace, technology, and healthcare with virtual tax preparation, monthly bookkeeping, and S-Corp structuring. We help aerospace subcontractors manage contract-based revenue recognition and B&O manufacturing classification, assist tech company founders with stock option exercises and R&D credit documentation, and provide fractional CFO services for healthcare practices managing provider compensation and insurance reimbursement complexity.
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.
