Washington Income Tax Calculator

How to Use This Washington Income Tax Calculator

This Washington income tax calculator estimates your annual federal income tax and FICA liability for 2025 and 2026. Enter your gross wages, filing status, and any pre-tax deductions above. Washington has no state income tax on wages — the calculator computes federal income tax and Social Security/Medicare only.

For per-paycheck withholding and take-home pay broken down by pay period, use the Washington paycheck calculator. To compare Washington's total tax burden against states that do have income taxes, use the general income tax calculator.

Washington State Income Tax — Zero on Wages

Washington is one of nine states with no individual income tax on wages. The Washington State Constitution requires that taxes on property be uniform, and courts have interpreted this to prohibit a graduated income tax — the most common form of state income tax — without a constitutional amendment passed by voters.

As a result, the annual tax filing picture for most Washington wage earners is simpler than for residents of income-tax states:

• No Washington state income tax return — there is no annual WA state income tax return to file for wages. Washington wage earners only file federal Form 1040.
• No state withholding on paychecks — the state withholding line on a Washington paystub is $0.00.
• No local income tax — no Washington city, county, or district imposes a local income tax on wages.

Washington Capital Gains Tax — Important Exception

While wages are untaxed at the state level, Washington enacted a 7% capital gains excise tax effective 2023, applying to net long-term capital gains above $270,000 per year. Key points:

• Threshold: $270,000 per individual (2026) — gains up to this amount are fully exempt.
• What it covers: Long-term capital gains from stocks, bonds, mutual funds, and business interests.
• What it excludes: Wages, salary, self-employment income, real estate gains on primary residences (up to federal exclusion limits), retirement account distributions, and most ordinary income.
• Who it affects: High-income investors, business sellers, and those with large stock portfolios. The vast majority of Washington wage earners owe $0 under this tax.

This calculator focuses on wage income and does not compute the Washington capital gains tax. If you have significant investment gains, consult a Washington CPA.

Federal Income Tax for Washington Residents

Federal income tax is the dominant tax on Washington wages. The US federal system uses progressive brackets — the same rates apply in Washington as in every other state.

Step-by-Step Example — $100,000 Washington Single Filer (2026)

1. Gross wages: $100,000
2. Federal standard deduction: −$16,100 → federal taxable income: $83,900
3. Federal income tax (10%/12%/22% brackets): ≈ $13,170
4. FICA: $100,000 × 7.65% = $7,650
5. Washington state income tax: $0.00
6. Total annual taxes: $13,170 + $7,650 = $20,820
7. Annual net income: $100,000 − $20,820 = $79,180

A comparable single filer earning $100,000 in Oregon pays roughly $8,500–$9,000 in Oregon state income tax on top of this, leaving them with approximately $70,000–$71,000 after all taxes — about $8,000–$9,000 less than a Washington resident.

Washington PFML — A Payroll Premium, Not Income Tax

Washington's Paid Family & Medical Leave (PFML) program does create a payroll deduction that Washington employees see on their paystubs. In 2026:

• Total PFML rate: approximately 0.74% of gross wages (set annually by the Washington Employment Security Department).
• Employee share: roughly 0.45% (employers with 50+ employees pay the balance; smaller employers may shift more to employees).
• Annual cost to employee at $100,000: approximately $450/year.
• Cap: PFML premiums are capped at the Social Security wage base.

PFML premiums fund paid leave benefits (up to 18 weeks per year for qualifying events) — they are not an income tax but a social insurance premium, similar to Social Security and Medicare at the federal level.

How Washington Compares to Neighboring States

• vs. Oregon:Oregon has progressive income tax brackets from 4.75% to 9.9% (2026) with no sales tax. At $100,000, an Oregon single filer pays roughly $8,500 more in income tax than a Washington resident. Oregon's lack of sales tax partially offsets this for consumers, but for most wage earners Washington is the lower-tax state.
• vs. Idaho: Idaho charges a flat 5.695% income tax (2026). A $100,000 Idaho single filer pays roughly $4,800–$5,200 in state income tax — money a Washington resident keeps.
• vs. California:California taxes income at 1%–13.3%. A $100,000 single California filer pays approximately $6,000 in state income tax; a $200,000 earner pays about $18,000. Washington's advantage over California grows rapidly at higher incomes.
• vs. Texas and Florida: Like Washington, Texas and Florida have no state income tax on wages. The primary differences are sales tax rates and property tax levels. Compare with the Texas income tax calculator.

How to Minimize Federal Income Tax as a Washington Resident

Since there is no Washington state income tax to plan around, tax optimization for Washington residents focuses entirely on federal strategies:

• Maximize traditional 401(k) contributions — the 2026 limit is $23,500 ($31,000 age 50+). At the 22% federal bracket, every $1,000 contributed saves $220 in federal tax. Maxing at $23,500 saves approximately $5,170.
• Fund an HSA — $4,300 individual / $8,550 family in 2026. Reduces federal taxable income dollar-for-dollar, and distributions for qualified medical expenses are tax-free. Through payroll, HSA contributions also avoid FICA.
• Contribute to a Dependent Care FSA — up to $5,000 per family for qualifying childcare expenses.
• Consider a Roth IRA or backdoor Roth — Washington has no state income tax, so there is no state tax on Roth conversions. For high earners who expect to remain in Washington, Roth accounts grow and withdraw tax-free both federally and at the state level.
• Qualified Opportunity Zones — Washington has several designated Opportunity Zones where capital gains invested for 10+ years can be excluded from federal capital gains tax. Relevant for investors with significant gains.
