Accounting & Tax Services in Vancouver, WA

Vancouver, Washington occupies a unique position at the intersection of two state tax systems. Situated directly across the Columbia River from Portland, Oregon, Vancouver businesses benefit from Washington’s zero state income tax while maintaining direct access to the Portland metro economy of over 2.5 million people. This border advantage has driven rapid population growth, making Clark County one of the fastest-growing metros in the Pacific Northwest. PeaceHealth Southwest Medical Center, Banfield Pet Hospital (national headquarters), and SEH America anchor a healthcare and corporate employment base that supports thousands of small businesses.

The Washington/Oregon border creates distinct tax planning opportunities and complexities. Washington imposes no income tax but applies B&O tax on gross receipts, while Oregon charges income tax up to 9.9% but has no sales tax. Vancouver businesses with employees or customers in both states must carefully manage nexus, payroll withholding, and entity location to maximize advantages. Georgia-Pacific and a growing cluster of technology companies relocated from Portland add manufacturing and tech depth to the local economy.

SDO CPA works with Vancouver business owners across technology, healthcare, and professional services to structure entities, optimize S-Corp reasonable compensation, and manage the interplay between federal tax obligations and Washington’s B&O tax. For businesses along the Vancouver Waterfront or in the growing Fourth Plain corridor, 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 Vancouver businesses overpay because they file under the wrong classification or miss available credits. Proper classification review can reduce your B&O liability significantly.

Vancouver is home to over 12,000 small businesses and a population of 190,915. From Technology, Healthcare, Manufacturing to professional services, Vancouver business owners need CPAs who understand Washington/Oregon cross-border tax complexity and multi-state employee management and can provide year-round tax planning — not just compliance.

What is the difference between a bookkeeper and a CPA?

Yes. Our fractional CFO services provide cash flow forecasting, budgeting, financial modeling, and strategic planning for Vancouver businesses generating $500K+ in revenue that need financial leadership without a full-time hire.
Should my Vancouver business be an S-Corp or LLC?
