No income tax, one premium
Washington has no personal income tax, so nothing is withheld for the state as income tax. One deduction does reach a bonus: the WA Cares Fund long-term-care premium of 0.58% of gross wages. Its employer page notes that, "unlike Paid Leave, premium contributions are not capped at the taxable maximum for social security," so it applies to the whole bonus — $29.00 on $5,000 and $116.00 on $20,000. The net check on the standard example is $3,488.50.
The capital gains tax is not a wage tax
The Department of Revenue's capital gains page describes Washington's 7% tax on sales or exchanges of long-term capital assets such as stocks and bonds. It does not apply to wages or bonuses, though it can apply when shares from an equity award are later sold at a large gain.
Paid Leave and Oregon jobs
Washington Paid Family and Medical Leave premiums are also deducted from wages; we could not verify the 2026 premium split today, so that deduction is not included. Washington residents who work in Oregon are withheld at Oregon's 8% supplemental option on a separately paid bonus ($400.00 on $5,000).
