Payroll in Washington

Payroll runs, payroll tax compliance, and quarterly filings handled end to end — including the state-specific rules most national providers gloss over.

Washington has no state income tax, which makes it an attractive place to build a company — but the state makes up for it with a Business & Occupation (B&O) tax structure that's classified by activity type, and misclassifying your business is one of the most common (and expensive) mistakes we see when we take over books from a prior bookkeeper in Seattle, Bellevue, Tacoma, or Spokane. We correct B&O classification, track the state's 6.5% sales tax plus local rates that push close to 10% in Seattle, and build investor-ready financials for the tech startups that make up a huge share of our Washington client base — because a seed or Series A diligence process moves a lot faster when your books are already clean. Washington employers also navigate WA Paid Family & Medical Leave, the WA Cares long-term-care premium, and for the largest employers, Seattle's payroll expense tax. Beyond tech, we work with professional services firms, healthcare practices billing Apple Health through ProviderOne, and e-commerce companies managing multi-state sales tax exposure that starts with getting Washington right. Every engagement runs on the same flat published pricing and business-day-5 close as our other states.
