Find a Startup CPA in Washington
CPAs who handle the tax, entity, and compliance side of running a startup — Delaware incorporation, R&D credit filings, and multi-state nexus — distinct from the bookkeeping-and-investor-reporting work a startup accountant handles. Serving businesses across Washington — Seattle's tech corridor and aerospace base drive demand for Washington's CPAs and tax professionals.

Washington tax climate
Washington has no state personal or corporate income tax. Instead, the Business & Occupation (B&O) tax applies to gross receipts at rates that vary by activity. A 7% capital gains tax on long-term gains above $262K (2024) applies to high earners. Sales tax averages around 9.4% combined.

- You're preparing tax-related materials for due diligence

- C-corp, LLC, and Delaware entity tax filings
- R&D tax credit calculation, documentation, and filing

FAQ
Startup CPAs in Washington — common questions
How much does startup cpas cost in Washington?+
Washington startup cpas typically charge $1,200–$6,000 per year for core tax compliance. Basic annual entity tax filing runs $1,200–$3,000/year for early-stage companies. Add R&D credit studies ($1,500–$5,000+ depending on complexity) and multi-state filings as needs grow. Ongoing monthly advisory is typically separate from core tax compliance.
Do I need a Washington-licensed CPA?+
For Washington state filings, your preparer should hold a CPA license from the Washington Board of Accountancy or be an Enrolled Agent. Out-of-state pros can prepare your federal return but should not sign as a CPA on Washington returns. Washington has no state personal or corporate income tax.
What's the difference between a startup CPA and a startup accountant?+
A CPA is licensed to file and sign tax returns and represent you before the IRS — core work like entity filings, R&D credits, and multi-state compliance. A startup accountant or bookkeeper typically handles monthly books and investor reporting; many startups use both.
Do early-stage startups really need a CPA if we're pre-revenue?+
Yes, at minimum for annual entity tax filings and Delaware franchise tax, which are due regardless of revenue. R&D credit eligibility often applies even pre-revenue, which a CPA should evaluate.
How does the R&D tax credit work for startups?+
It rewards qualifying product-development activity — much of what early engineering teams do. Pre-revenue startups can often apply the credit against payroll tax liability rather than income tax, which a CPA calculates and files.
What triggers the need for multi-state tax filings?+
Having employees, contractors, or significant sales activity in a state can create nexus, obligating you to register and file there — remote-first teams often trigger this without realizing it.
Should our CPA be different from our fractional CFO?+
Often yes — many startups use a CPA for tax/entity compliance and a separate fractional CFO for forecasting, fundraising support, and strategy, with the two coordinating directly.
