|---|---|---|
| Business and occupation (B&O) tax | Most businesses in Washington: a tax on gross receipts, with no deduction for labor, materials or other costs; the rate depends on which of more than 50 classifications the work falls under | Charged on all $85,000 of receipts, not the $70,000 profit at the page's default expenses; this calculator does not price it because the rate depends on your classification |
| Small Business B&O credit | Businesses with 50% or more of their income under Service and Other Activities whose B&O tax for the year is below $3,840 (annual filers, periods after January 1, 2023) | Reduces or removes the B&O tax under that limit; the Department of Revenue figures it when you file electronically |
