Washington tax climate

The local tax environment

State tax overview

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.

Tax rates and rules change frequently. Verify current figures with a licensed professional before acting.

What this means for you

  • A local tax prep understands Washington-specific filing requirements.
  • Multi-state nexus and remote-worker rules vary — ask about your exposure.
  • Entity election and pass-through tax options are state-specific.
