State playbook - Washington

Matchbook, tuned for Washington payroll, programs, and storms.

Washington has no state income tax on wages - but a 7% tax on long-term capital gains over the standard deduction, a Seattle JumpStart payroll expense tax on high earners, WA Paid Family and Medical Leave, and the 0.58% WA Cares Fund long-term care payroll tax all reshape the Section 125 calculus. Add Seattle's Commuter Benefits Ordinance, Fair Start for Kids, and Cascade Care Savings, and the levers most national broker ROI decks miss are state-specific and large.

What Matchbook ships for Washington Tax profile
Tax mechanics

Payroll tax in Washington

State income tax

No state income tax

Washington does not tax wage income, so the Section 125 salary-reduction stack for employees is federal marginal rate plus 7.65% FICA plus WA Cares 0.58% plus the employee share of PFML. What is different from Florida: Washington imposes a 7% long-term capital gains tax (tiered - 7% on the first $1M of taxable gains above the standard deduction, 9.9% above $1M, standard deduction $278,000 for 2025) and the Seattle JumpStart payroll expense tax on high-compensation employees of large Seattle-payroll employers. Matchbook recalculates employee marginal stacks at 0% on wage income but surfaces capital-gains tax planning for employees with RSU vesting, secondary sales, or equity liquidity events.

Washington Unemployment Insurance

Wage base $72,800 (2025); rising to $78,200 (2026)

Rate range: About 0.27%-6.02% for experienced employers in 2025; 2026 range shifts to 1.25%-8.15% for delinquent rated employers; new employer rate is industry-specific, generally 90% of the industry average and not less than 1%

Washington's UI wage base is one of the highest in the country - about ten times Florida's. That means Section 125 salary reductions produce real employer UI-tax savings for a much larger share of the workforce than in low-wage-base states. Matchbook retains the UI savings line in the Washington employer ROI report and models it per employee against the current $72,800 ($78,200 in 2026) wage base rather than using a flat rate.

Employer FICA

7.65% / 1.45% split

Employer FICA is 7.65% on wages up to the Social Security wage base ($176,100 in 2025; $184,500 in 2026) and 1.45% above it. Layered on top in Washington: employer PFML share (28.57% of 1.13% in 2026, on wages to $184,500), and for Seattle employers above the JumpStart threshold, payroll expense tax of 0.746%-2.557% plus the new 5% Social Housing Tax on individual compensation over $1M (retroactive to January 1, 2025).

Employer credits and levers

State and federal credits worth stacking

Credits that most broker ROI decks omit. Matchbook surfaces these in the employer report.

Washington Main Street Tax Credit

B&O and public utility tax credit equal to 75% of contributions made to an approved Main Street organization or the Main Street Trust Fund. Annual per-business contribution cap, with statewide program cap; April 1 and October 1 contribution windows. Direct B&O liability offset for employers in a B&O-heavy state with no corporate income tax.

Source →

B&O Rural County / CEZ new-employee credit

B&O credit for manufacturers, R&D facilities, and commercial testing facilities that create net new full-time positions in a qualifying rural county or Community Empowerment Zone. Requires at least a 15% increase in average employment at the qualifying facility over the four calendar quarters following the hire.

Source →

Federal IRC Section 45F (employer-provided childcare)

Federal employer-provided childcare credit. 25% credit with $150K cap in 2025; rises to 40% with $500K cap in 2026, and 50% with $600K cap for small employers. Washington has no state analog, so the federal credit is the sole on-site/sponsored care lever - still worth modeling for Puget Sound employers with childcare deserts.

Source →

Seattle JumpStart Payroll Expense Tax (expense, not credit)

Seattle imposes a payroll expense tax on companies with 2024 Seattle payroll of $8,837,302 or more, on compensation paid to any employee earning $189,371 or more in 2025. Rates 0.746%-2.557% depending on payroll tier and individual compensation. Proposition 1A (effective January 1, 2025) adds a 5% Social Housing Tax on per-employee compensation over $1M - combined top rate of 7.557% on the highest-paid Seattle employees at the largest employers.

Household programs

State programs that change what your employees should elect

Matchbook coordinates these against DCFSA, FSA, and HSA elections at the household level.

Childcare subsidy

Working Connections Child Care (WCCC)

Washington's subsidized childcare program, expanded under the Fair Start for Kids Act. Co-pays capped and eligibility extended; however, the 2025-27 state budget delayed further income-eligibility expansion and removed the childcare-worker expansion for new applicants and reauthorizations starting July 1, 2025.

Matchbook: WCCC reduces out-of-pocket dependent-care cost and therefore changes the right DCFSA election. Matchbook's Washington screener ingests current WCCC eligibility and copay tables before recommending DCFSA contribution levels.

Source →

Preschool

ECEAP and Transition to Kindergarten

ECEAP is Washington's state-funded preschool for income-eligible 3- and 4-year-olds. Transition to Kindergarten (TK) was authorized statewide by the 2023 Legislature as a voluntary program for 4-year-olds who need additional preparation and lack access to other early learning. Combined state-funded preschool enrollment exceeded 21,000 in 2023-24.

Matchbook: For families using ECEAP or TK plus wrap-around care, the correct DCFSA election is the wrap-around cost, not zero. Matchbook models the split explicitly for Washington households.

Source →

Policy framework

Fair Start for Kids Act

Signed in 2021, the Fair Start for Kids Act is a multi-billion-dollar investment in early learning - child care, preschool, and infant-toddler programs. It frames Washington's childcare subsidy copays, provider rates, and eligibility expansions; tracking legislative updates is necessary to keep employer benefits recommendations accurate.

Matchbook: Matchbook follows FSKA implementation rules each budget cycle and updates Washington household recommendations as copay tables and eligibility thresholds change.

Source →

Health programs

Coverage coordination checkpoints

Apple Health for Kids (Medicaid/CHIP)

Free for children in households at or below 215% FPL; premium coverage available up to 312% FPL (monthly premium $30 per child above 260% FPL). Birth-to-age-6 continuous coverage on the free tier; 12-month continuous coverage on the premium tier.

Matchbook: Washington has one of the highest children's Medicaid/CHIP income ceilings in the country. Employees declining dependent coverage should be screened against the 312% FPL premium threshold before Matchbook defaults them to the family tier.

Source →

Washington Healthplanfinder - Cascade Care Savings

Washington operates its own state exchange. Cascade Care (public option) plans are available alongside standard ACA plans. Cascade Care Savings provides $55 per member per month for most enrollees up to 250% FPL in 2026, and $250 per member per month for income-eligible enrollees ineligible for federal subsidies (including undocumented Washingtonians). Washington adopted premium alignment (silver loading) for 2026 to preserve Gold-plan affordability after federal enhanced PTC expired.

Matchbook: If employer family coverage exceeds the 2026 ACA affordability threshold, Matchbook surfaces the Washington Healthplanfinder dependent path with Cascade Care Savings stacked on federal PTC where eligible.

Source →

WA Paid Family and Medical Leave (PFML)

Premium rate rises to 1.13% of wages in 2026 (from 0.92% in 2025), applied to wages up to the Social Security wage base ($184,500 in 2026). Employer share 28.57%; employee share 71.43%. Employers with fewer than 50 Washington employees are exempt from the employer share but must still collect or pay the employee share. Voluntary plan option available.

Matchbook: PFML interacts with short-term disability and FMLA leave stacking. Matchbook models leave-benefit coordination at the household level so employees do not over-elect voluntary STD or leave-buy-up when PFML already covers the gap.

Source →

WA Cares Fund (state long-term care)

Mandatory 0.58% employee-only payroll tax, no wage cap, withheld by employers since July 1, 2023. Benefits of up to $36,500 (inflation-adjusted) begin July 2026. SB 5291 (May 2025) expanded eligibility pathways - contributed 10+ years at 500+ hours/year, or 3 of last 6 years; previously-exempt employees may rejoin; out-of-state workers may maintain coverage.

Matchbook: Section 125 salary reductions reduce the WA Cares base because the tax is on wages, so HSA/FSA/DCFSA/132(f) elections each produce a 0.58% WA Cares savings per dollar on top of FICA and federal marginal savings. Matchbook adds the 0.58% line in the Washington employee savings stack - small per dollar but uncapped. Matchbook also screens employees for a private LTC policy that may qualify for WA Cares exemption (exemption windows are closed for new private policies, but Matchbook tracks the exemption status of employees who already qualified).

Retirement and wealth

State-level retirement and wealth context

Washington ABLE Savings Plan

Washington's Section 529A program for disabled beneficiaries. 2025 contribution limit $19,000; employed beneficiaries may add up to $15,060 more. $500K balance cap; $100K SSI asset exclusion.

Matchbook: FSA or HSA dollars reimburse medical expenses; ABLE covers broader qualified disability expenses. When SSI asset limits are in play, Matchbook routes disability-related spend to ABLE first. No Washington income tax means no state deduction loss when using an out-of-state 529A.

Source →

WA529 (GET and Invest / DreamAhead)

GET is Washington's 529 Prepaid Tuition program, state-guaranteed to keep pace with the most expensive Washington public undergraduate tuition. WA529 Invest (formerly DreamAhead) is the direct-sold 529 savings plan. Because Washington has no state income tax, there is no home-state deduction tilt - residents can use any state's 529 plan without penalty.

Matchbook: Matchbook does not over-weight WA529 for Washington families when evaluating college-savings strategy; it evaluates GET specifically when tuition-rate hedging matches the household's risk profile.

Section 132(f) commuter

Pre-tax commuter reality in Washington

2025 IRC Section 132(f) cap is $325 per month for transit and $325 per month for qualified parking. 2026 cap is projected to rise again with inflation indexing.

Parking and state credits

Parking: Seattle CBD and South Lake Union monthly parking routinely exceeds the $325 monthly cap; Bellevue, Redmond, and Tacoma parking often sits at or below the cap. Matchbook flags Seattle parkers whose 132(f) election is capped below their actual cost and surfaces the ORCA Passport / business pass alternative.

State credit: Washington has no state-level commuter tax credit. Seattle's Commuter Benefits Ordinance (effective January 1, 2020) requires employers with 20+ employees to offer covered employees (10+ hours/week in Seattle) a monthly pre-tax transit/vanpool deduction or an employer-paid transit pass. Matchbook uses Seattle's ordinance as the default 132(f) setup for qualifying employers and reconciles to the ORCA Business passport program.

Disaster readiness

Washington disaster-relief playbook

IRC Section 139 qualified disaster relief payments are not W-2 wages: no FICA, no FUTA, no federal income tax withholding, and the employer gets a full deduction. Triggered by a federal disaster declaration. Washington's recent qualifying events include severe storms, straight-line winds, flooding, landslides and mudslides (December 2025 declaration covering 23 counties and multiple tribal nations), a February 2024 Spokane County declaration, and recurring wildfire and winter-storm declarations. Cascadia earthquake preparedness remains a background risk.

  • Pre-drafted Section 139 policy template so employers can disburse tax-free relief within 48 hours of a federal declaration - Washington DR numbers populate automatically from FEMA.
  • Post-event Section 125 election-change guidance: a storm or wildfire alone is not a listed change-in-status event under Treas. Reg. 1.125-4 - it qualifies only when it triggers a change in residence, employment, or cost-of-coverage.
  • FEMA Individual Assistance interaction: Section 139 payments generally stack with FEMA IA, but Matchbook flags duplication risk in the disbursement log.
  • WA PFML interaction: employees displaced by disaster may qualify for paid leave under specific PFML event types; Matchbook checks whether Section 139 cash relief should be paired with, or offset against, PFML claim timing.
  • Wildfire-smoke leave review: Washington L&I has adopted outdoor-air-quality rules for wildfire smoke; employer policy should reference L&I standards when absence is smoke-driven.
Matchbook for Washington

What we ship specifically for Washington employers

  • No-wage-tax calibration of the employee savings engine - recompute marginal stacks at 0% state on wages and add a 0.58% WA Cares line (uncapped) plus 71.43% x 1.13% PFML line (capped at SS base) to each pre-tax election.
  • Capital-gains surcharge planner for employees with equity liquidity events - 7% Washington long-term capital gains tax above the 2025 $278,000 standard deduction, 9.9% above $1M of gains - integrated with RSU vesting and ESPP disqualifying-disposition logic.
  • Seattle JumpStart exposure modeling for employers above the payroll threshold - JumpStart plus Social Housing Tax combined rate of up to 7.557% on compensation over $1M, which changes the value of non-cash compensation design (deferred comp, 401(k) match, HSA seed).
  • Seattle Commuter Benefits Ordinance compliance default for employers with 20+ covered Seattle employees - auto-enroll 132(f) pre-tax transit deductions and reconcile against ORCA Business.
  • WCCC / ECEAP / Transition to Kindergarten integration in the DCFSA recommender, ingesting DCYF eligibility and copay tables as they update through Fair Start for Kids Act cycles.
  • Apple Health for Kids screener at open enrollment (312% FPL premium threshold) to capture dependents who qualify for state coverage instead of the employer family tier.
  • Cascade Care Savings path surfaced when employer family coverage fails the 2026 ACA affordability test - Washington-specific because of the $55 PMPM state top-up and the $250 PMPM subsidy for federal-ineligible enrollees.
  • IRC Section 139 storm/wildfire/flood playbook template with pre-drafted employer policy and post-event Section 125 election-change guidance keyed to Washington DR numbers.
  • WA Cares exemption tracker for grandfathered private-LTC opt-outs and SB 5291 rejoin events.
  • Benefits graph ingests: WA DOR B&O and Main Street credit data, WA ESD UI rate notices and 2026 wage base, WA PFML 2026 premium updates, WA Cares exemption status, Seattle OLS Commuter Benefits enforcement data, DCYF WCCC/ECEAP/TK eligibility, WA HBE Cascade Care Savings schedules, and FEMA DR numbers for Washington.
