Accounting & Tax Services in Spokane Valley, WA

Spokane Valley stretches along the I-90 corridor just east of Spokane, with the Sprague Avenue commercial strip and Sullivan Road retail district serving as primary business centers. The city incorporated in 2003 and has grown into one of Washington’s largest cities, attracting businesses with lower commercial rents and a pro-business environment compared to western Washington. MultiCare Valley Hospital and Kaiser Permanente facilities anchor the local healthcare sector, while manufacturers along the Trent Avenue industrial corridor produce building materials, agricultural equipment, and food products. Spokane Valley’s position 15 miles from the Idaho border creates unique multi-state complexities, as many businesses serve customers on both sides of the state line — navigating Washington’s B&O tax structure on the west and Idaho’s income tax system on the east. Retail and service businesses along the Spokane Valley Mall area and Mirabeau Point district serve a combined Spokane metro population exceeding 570,000. SDO CPA works with Spokane Valley business owners across healthcare, retail, and manufacturing to manage B&O tax classification, handle multi-state filing between Washington and Idaho, and optimize S-Corp structures. We help healthcare practices with provider compensation analysis, assist manufacturers with equipment depreciation planning, and provide monthly bookkeeping for retailers managing multiple locations across the Spokane metro.

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.

Spokane Valley is home to 5,000+ small businesses and a population of 105,460. From Healthcare, Retail, Manufacturing to professional services, Spokane Valley business owners need CPAs who understand Cross-border tax obligations for businesses serving customers in both Washington and Idaho with different tax structures and can provide year-round tax planning — not just compliance.
