Washington Paycheck Calculator (2026)

Estimate your Washington take-home pay after federal income tax and FICA. Washington has no state income tax.

How this calculator works

Washington has no state income tax on wages or salaries, so your paycheck deductions are federal income tax and FICA only. This calculator takes your gross pay, subtracts any pre-tax 401(k) and health-insurance deductions, computes federal income tax and FICA on what’s left, and divides the year’s total by your number of pay periods to estimate what lands in your account each paycheck.

The formula

grossAnnual        = salary, or hourlyRate × hoursPerWeek × 52
ficaWages          = grossAnnual − pretaxHealth        (401(k) does NOT reduce FICA wages)
fedTaxableWages    = grossAnnual − pretaxHealth − 401(k) contribution
taxableIncome      = max(0, fedTaxableWages − standardDeduction)

FICA   = 6.2% of ficaWages (up to the $184,500 wage base)
     + 1.45% of ficaWages (no cap)
     + 0.9% of ficaWages over $200,000

federalTax = 2026 bracket engine applied to taxableIncome
stateTax   = $0 (Washington has no state income tax on wages)

net = grossAnnual − pretaxHealth − 401(k) − FICA − federalTax − stateTax − postTaxDeductions
netPerPaycheck = net / payPeriodsPerYear

Worked example

A single filer earning $60,000/year, paid biweekly, with no 401(k) or extra deductions:

  • FICA: 7.65% × $60,000 = $4,590.00/year ($3,720 Social Security + $870 Medicare)
  • Taxable income: $60,000 − $16,100 standard deduction = $43,900 → federal tax = $5,020.00/year
  • Net pay: $60,000 − $4,590 − $5,020 = $50,390.00/year, or $1,938.08 per biweekly paycheck

This is the same arithmetic as our Texas and Florida calculators’ worked examples, since all three states have $0 state income tax on wages; only the state-specific content differs. Washington also has a capital gains excise tax and, starting in 2028, a tax on household income above $1 million, but neither one touches wage or salary income, so neither changes this result.

Frequently asked questions (FAQ)

Why doesn't Washington have a state income tax?

The Washington Supreme Court ruled in Culliton v. Chase (1933) that a graduated tax on income violates the state constitution's uniformity clause (Article VII, Section 1), which treats income as property that must be taxed at one uniform rate. That ruling has never been overturned, so Washington has no tax on wages or salaries.

Does Washington's capital gains tax affect my paycheck?

No. Washington's capital gains excise tax only applies to profits from selling long-term assets like stocks and bonds above an annual exemption amount. It does not touch wage or salary income, so it never shows up as a paycheck deduction.

What is the new Washington "millionaire's tax," and does it apply to my wages?

Washington enacted a 9.9% tax on household income above $1 million (ESSB 6346) in 2026, and it would include wages once active. It does not take effect until January 1, 2028, with first payments due in 2029, so it has no effect on 2026 paychecks and is not modeled by this calculator.

What is FICA?

FICA is the combined 7.65% Social Security (6.2%) and Medicare (1.45%) tax withheld from your paycheck, matched by your employer. Social Security stops once your wages hit the annual wage base ($184,500 for 2026); Medicare has no cap and adds an extra 0.9% above $200,000.

How does contributing to a 401(k) change my take-home pay?

A traditional 401(k) contribution lowers the wages your federal income tax is calculated on, so it shaves a bit off your income tax bill, but it does not reduce your Social Security or Medicare wages, since those are calculated before the 401(k) deduction.

Why doesn't my calculated net pay match what shows up in my actual paycheck?

This calculator estimates your annual tax liability and divides it evenly across your pay periods. Your actual employer withholds federal tax per paycheck using IRS withholding tables, which can differ slightly period-to-period; the two methods land close together but rarely to the exact cent.
