Washington State Paycheck Calculator

Federal income tax is the largest single deduction from most paychecks, including those earned in Washington State. Even though Washington has no state income tax, every employee remains fully subject to federal income tax withholding under IRS rules. The amount withheld each pay period is determined by your filing status, the number of pay periods per year, and the elections you record on your Form W-4. The 2020 redesign of the W-4 eliminated the old allowances system and replaced it with a more transparent approach that asks directly for estimated additional income, anticipated deductions, and any credits you expect to claim on your return.

Federal income tax uses a progressive bracket structure with rates of 10%, 12%, 22%, 24%, 32%, 35%, and 37% for 2024. However, the effective rate that actually hits your paycheck is almost always lower than the top bracket because each bracket only applies to income within its range, not your entire gross pay. A single filer earning $65,000 per year faces an effective federal rate of roughly 13% to 15% after accounting for the standard deduction of $14,600. Your employer uses IRS Publication 15-T withholding tables to calculate the correct federal tax for each paycheck automatically.

Pre-tax deductions are one of the most powerful levers you have to reduce your federal withholding and increase take-home pay. Common pre-tax benefits include contributions to an employer-sponsored 401(k) or 403(b) plan, health and dental insurance premiums under a Section 125 cafeteria plan, and contributions to a Flexible Spending Account (FSA) or Health Savings Account (HSA). For example, if you earn $6,000 per month and contribute $600 to a 401(k) and $250 to pre-tax health insurance, your federally taxable wages drop to $5,150 — materially reducing the amount withheld. You can adjust your elections during your employer's open enrollment period or following a qualifying life event.

FICA — the Federal Insurance Contributions Act — mandates two flat-rate payroll taxes that fund Social Security and Medicare. Unlike federal income tax, FICA has no progressive brackets, no filing status adjustments, and no standard deduction. Every W-2 employee, regardless of state of residence, pays the same percentage of gross wages into each program up to the applicable limits. These contributions fund the Social Security retirement and disability programs that pay benefits to over 70 million Americans, and the Medicare program that provides health coverage for Americans aged 65 and older and certain disabled individuals.

Social Security tax is assessed at 6.2% of gross wages up to the annual wage base of $168,600 for 2024. Once your cumulative wages in a calendar year exceed that threshold, Social Security withholding ceases for the remainder of the year — producing a noticeable increase in take-home pay for high earners in the latter months. Medicare tax is levied at 1.45% of all gross wages with no earnings cap. Employees earning more than $200,000 per year are also subject to an Additional Medicare Tax of 0.9%, which employers are required to begin withholding automatically when wages cross that level.

Your employer matches your FICA contributions dollar for dollar. They pay 6.2% in Social Security and 1.45% in Medicare on your behalf, meaning the combined employer-and-employee FICA contribution totals 15.3% of your wages. Self-employed individuals pay both halves themselves as self-employment tax but can deduct the employer-equivalent portion from their adjusted gross income. For a Washington State employee earning $75,000 annually, the employee-side FICA deduction amounts to approximately $5,738 per year — $4,650 for Social Security and $1,088 for Medicare — making it the second-largest payroll deduction after federal income tax.

Washington State administers workers' compensation through the Department of Labor and Industries (L&I), which operates as a state-managed monopoly fund rather than a competitive private insurance market. Almost all Washington employers are required to participate and to pay premiums to L&I that cover medical expenses, wage replacement, and other benefits if an employee is injured on the job or develops a work-related illness or disease. Washington is one of a small number of states where employees also directly contribute to the workers' compensation premium, with their share deducted from each paycheck.

The L&I premium rate is expressed as a dollar amount per hour worked and varies significantly by job classification and industry risk level. A software developer working in an office environment pays a far lower rate than a construction laborer or a warehouse employee who performs physically demanding tasks. Rates are reviewed and updated annually by L&I based on actuarial analysis of claims experience in each risk classification. Your employer's HR or payroll department can provide your specific risk class code and the current employee premium rate per hour so you can calculate the exact deduction from your paycheck.

Employees injured on the job file a claim directly with L&I, which then manages the claim process, authorizes medical treatment, and pays wage replacement benefits. Wage replacement through L&I is typically paid at roughly 60% to 75% of the worker's gross weekly wage, subject to state minimum and maximum benefit levels. Washington's L&I system is funded entirely by employer and employee premiums; it does not draw on general state tax revenue. If you are misclassified under the wrong risk code, your premium deduction may be incorrect, so it is worth confirming with your employer that your classification accurately reflects your actual job duties.

Washington State's Paid Family and Medical Leave program, administered by the Employment Security Department, provides eligible employees with up to 12 weeks of paid leave per year to bond with a new child, recover from a serious personal health condition, or care for a family member with a serious health condition. An additional two weeks may be available for pregnancy-related conditions. The program is funded through a combined employer-employee premium collected from payroll each pay period, making it a line item that appears on every Washington worker's pay stub.

For 2024, the total PFML premium rate is 0.74% of gross wages up to the Social Security wage base. Employees pay approximately 71.43% of the total premium — roughly 0.529% of gross wages — while employers with 50 or more employees cover the remaining 28.57%. Employers with fewer than 50 workers are not required to pay the employer share but must still withhold and remit the employee portion. The premium is assessed on wages before most pre-tax deductions, so your PFML contribution is based on a broader wage figure than your federal taxable wages.

When an employee takes approved PFML leave, the program replaces approximately 90% of the employee's average weekly wage up to the state average weekly wage, and 50% of wages above that threshold, subject to a weekly maximum benefit that increases each year. Employees must have worked at least 820 hours during the qualifying period — generally the first four of the five most recently completed calendar quarters — to be eligible for benefits. Unlike the WA Cares Fund, there is no opt-out option for PFML even if you carry private leave insurance. The premium is automatically withheld and remitted by your employer without any action required on your part.

Your Washington State pay stub provides a complete accounting of every dollar earned and deducted in the pay period. The stub begins with your gross pay — the total compensation before any reductions — and then itemizes every deduction below it. Pre-tax deductions such as 401(k) contributions and health insurance premiums typically appear first, followed by the tax withholding section. In Washington, the tax section lists federal income tax, Social Security, Medicare, WA Paid Family and Medical Leave, WA Cares Fund (if applicable), and L&I workers' compensation. The final figure at the bottom is your net pay, which equals the amount deposited into your bank account.

Each pay stub also shows year-to-date (YTD) totals alongside the current-period amounts. The YTD columns let you track cumulative deductions across the entire calendar year and are especially useful for monitoring your Social Security withholding. Once your YTD gross wages reach $168,600, Social Security withholding stops, and your take-home pay rises noticeably in those later paychecks. Comparing your YTD federal income tax withheld against your estimated annual tax liability also helps you determine whether you are on pace for a refund or may owe a balance at filing — giving you time to adjust your W-4 before year-end if needed.

Washington law requires employers to provide employees with a pay stub (paper or electronic) each pay period, and that stub must include gross wages, all deductions by type, and net pay. If you notice a discrepancy — such as a missing pre-tax deduction, an unexpected change in withholding, or an L&I rate that looks wrong — contact your payroll department immediately. Keep your pay stubs throughout the year because they are the primary document for verifying your W-2 form at tax time, and lenders, landlords, and government benefit programs routinely require recent pay stubs as proof of income and employment status.
