How are bonuses taxed in Washington?

Washington has no tax on wages (its capital-gains tax does not apply to paychecks), so your bonus faces federal taxes and one state deduction: a flat 22% federal supplemental withholding (37% above $1 million), 7.65% for Social Security and Medicare, and WA payroll taxes (0.81% WA Paid Family & Medical Leave, 0.58% WA Cares): about 31.04% withheld up front. Withholding isn't your final tax: at filing time a bonus is ordinary income, so any over-withholding comes back as a refund. Against the 2 states Washington borders, the same a $10,000 bonus is worth $6,896 here: Idaho leaves $391 less ($6,505) and Oregon leaves $796 less ($6,100). Washington beats every state it borders on this, so the commute only pays in the other direction.

How Washington bonus withholding works

Short answer: a $10,000 bonus in Washington leaves $6,896, 69.0% of it, because the only deductions are the 22% federal supplemental rate, 7.65% FICA and WA payroll taxes (0.81% WA Paid Family & Medical Leave, 0.58% WA Cares). Bonuses aren't taxed at a higher rate, though: at tax time they're ordinary income, and any over-withholding comes back in your refund. Here's how each piece works.

  • Federal supplemental rate: Most employers withhold federal income tax from bonuses at a flat 22%, $2,200 on a $10,000 bonus, or 37% above $1 million a year, regardless of your regular bracket.
  • No Washington income tax: Washington has no tax on wages (its capital-gains tax does not apply to paychecks), so no state income tax is withheld. The one state deduction is WA payroll taxes (0.81% WA Paid Family & Medical Leave, 0.58% WA Cares), as from any wage. Against the 2 states Washington borders, the same a $10,000 bonus is worth $6,896 here: Idaho leaves $391 less ($6,505) and Oregon leaves $796 less ($6,100). Washington beats every state it borders on this, so the commute only pays in the other direction.
  • FICA taxes still apply: Social Security (6.2% up to the annual wage base) and Medicare (1.45%, plus 0.9% for high earners) come out of a bonus like any wage: $765 on $10,000.
  • Over-withholding is common: The flat 22% federal rate is often higher than your actual effective rate, and the difference comes back as a refund. In Washington the whole $10,000 nets $6,896 once FICA and WA payroll taxes are in.

Your actual bonus tax depends on your total annual income, not the bonus alone: these figures assume a $75,000 Washington salary. Enter your own numbers above for an estimate that fits your situation.

Washington taxes groceries at the full sales tax rate (unlike many states that exempt or reduce taxes on food), which can significantly impact lower-income families. Combined with sales tax rates that can reach 10%+ in some areas, big spenders may pay more in sales tax than they'd pay in income tax in moderate-tax states. A $200 weekly grocery bill includes $20+ in sales tax, and someone spending $10,000 annually on groceries pays $650-$1,000+ in sales tax, which can offset income tax savings for lower-income families.
