What's the effective tax rate in Washington on a $100K single salary in 2026?

Washington has no state income tax (1 of 9 such US states). A $100,000 single filer pays only $13,841 federal income tax + $7,650 FICA = $21,491 total → 21.5% effective rate. This is among the lowest single-filer effective rates in the US. The calculator above shows the exact number including 401(k) + HSA deductions.

If Washington has no state income tax, where does state revenue come from?

Washington funds public services primarily through sales tax (6.5% state + up to 4.1% local), property tax, and capital gains tax (7% on long-term gains over $262K). The combined state-and-local tax burden lands lower than typical income-tax states for renters and modest spenders. Median Washington household income is $91,306.

How much do I take home in Washington? — short answer first

Washington is one of nine US states with no personal income tax — but unlike Texas or Florida, Washington imposes substantial payroll-deduction programs that show up on every paycheck. The WA Cares Fund (long-term care insurance) deducts 0.58% on all wages with no cap, and the Paid Family + Medical Leave program (PFML) adds ~0.74% combined employee share. Net result: a typical Washington worker sees ~1.3% deducted from gross even before federal and FICA. Washington also has a 7% capital gains tax on long-term gains above $262K (2026 threshold), but this does not affect paycheck math. The state-and-local tax structure is sales-tax-heavy: 6.5% state + up to 4.1% local pushes Seattle to 10.35% combined.

How Washington taxes payroll in 2026

Washington has no state personal income tax — and a 2023 Supreme Court ruling on the capital gains tax confirmed the state constitution's interpretation that income is property, not subject to graduated taxation. However, two state-mandated payroll deductions reduce every Washington paycheck. First, the WA Cares Fund (long-term care insurance) deducts 0.58% on ALL wages with no cap, established under RCW 50B.04 and effective July 2023. WA Cares funds up to $36,500 of long-term care benefits per Washington resident over their lifetime — a lifetime cap, not annual. Second, the Paid Family + Medical Leave program (PFML) under RCW 50A.04 deducts approximately 0.74% as the employee share of the combined ~1.0% premium (employer covers the rest). PFML funds 12 weeks of paid leave for medical conditions, family caregiving, or new-child bonding. Combined, the two programs deduct ~1.32% of every Washington paycheck — small but not insignificant. The state also imposes a 7% capital gains tax on long-term capital gains exceeding $262,000 per year (2026 indexed threshold) under RCW 82.87 — but this does not appear on paychecks; it's filed annually on Form 1040 equivalent. Washington has no local income tax anywhere in the state. Local revenue comes primarily from sales tax (6.5% state + up to 4.1% local; Seattle 10.35% combined) and property tax (~0.93% effective statewide). For wage earners, Washington's net tax position falls between Texas-style 'pure no-income-tax' states and full-tax states — meaningfully better than CA/NY at gross levels above $50K, but worse than Texas or Florida for low-income earners due to high sales tax incidence.

How to use this calculator

Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and Washington brackets.
Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
Pick your locality. Drives local-tax stacking (NYC, Yonkers, etc). NONE if you live outside any locality with local payroll tax.
Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.

Common mistakes

Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
Not selecting your locality. If you live in a city with local payroll tax (NYC, Yonkers, etc.), the locality dropdown above is required for accurate math.
Ignoring multi-state implications. If you work in Washington but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in Washington.

Frequently asked questions

Does Washington really have no income tax?

Yes — on wages and salaries. Washington has no personal income tax under the state's constitutional 'uniform property tax' clause. However, two mandatory payroll deductions (WA Cares 0.58% + PFML ~0.74%) total ~1.3% of wages — not income tax in name but a real paycheck reduction. The 7% capital gains tax (>$262K) is filed separately, not withheld.

What is the WA Cares Fund and can I opt out?

WA Cares Fund (RCW 50B.04) is a state-run long-term care insurance program, deducting 0.58% of all wages with no cap. Benefits cap at $36,500 per lifetime. The opt-out window closed in November 2021 (one-time, required private long-term care insurance proof). New employees as of 2022+ cannot opt out and are mandatorily enrolled.

Does the 7% capital gains tax affect my paycheck?

No — Washington's 7% capital gains tax (>$262K threshold, 2026 indexed) applies only to long-term capital gains realised in a tax year, filed on a separate state return after federal Form 1040. It does NOT appear on paychecks and does NOT apply to wage income, 401(k) distributions, real estate gains, or sales of small businesses (most exemptions apply).

Is Washington really cheaper than Oregon for tech workers?

Usually yes — Oregon's top 9.9% state income tax kicks in at $125K single. A $200K Washington worker takes home ~$13K more than a $200K Oregon worker after state tax (even accounting for WA's ~1.3% payroll deductions). But Oregon has no sales tax (vs Seattle's 10.35%) — high-spending households see the gap shrink to ~$8-10K.
