Washington self-employment & S-corp rules
- State income tax: no state income tax. Self-employment tax itself (15.3%) is federal and identical in every state.
- Minimum franchise / LLC fee: $70/year for an LLC or S-corp in Washington, regardless of income.
- Also note: Washington has no income tax but levies a Business & Occupation (B&O) tax on gross receipts (rate varies by activity) that applies to sole proprietors and S-corps alike — not modeled in the savings above.
- PTET (SALT-cap workaround): Not available in Washington.
- No state income tax. 7% capital gains tax on long-term gains above $262,000 (2024) — narrow but applies. Property tax averages 0.94%.
