Self-employment tax in Washington
Washington has no individual income tax on earnings.
Washington charges no individual income tax, so only federal income tax and the 15.3% self-employment tax apply. The federal half never changes: 15.3% on 92.35% of net profit, then income tax on profit less half that SE tax, the standard deduction and up to 20% qualified business income.
The failure mode is cash, not arithmetic. Money lands, it gets spent, and the quarterly due date becomes a crisis. Hate Ledger moves the reserve out of reach the day each deposit clears, so the Washington and federal bills are funded before you see the money.
