Stripe RSU Taxes in Washington (2026)

2026 Stripe Compensation Benchmarks in Washington

Below is the 2026 tax withholding and April shortfall breakdown across sample Stripe engineering levels for a Single filer in Washington (at a reference share price of $42/share via Carta / Morgan Stanley at Work):

Washington Supplemental Tax Regulations for Stripe RSUs

Washington State levies 0% personal income tax on W-2 wages and ordinary income recognized at RSU vest. However, Washington enforces a 0.58% WA Cares Fund (Long-Term Services and Supports Trust Program) uncapped payroll premium on all W-2 wages and RSU vests unless you hold an approved exemption, plus a 7% Washington Capital Gains Excise Tax on post-vest capital gains exceeding the annual statutory standard deduction.

Washington Bracket Architecture: 0.00% personal wage income tax; 0.58% uncapped WA Cares payroll assessment (unless exempt); 7.0% excise tax on net long-term capital gains above the statutory threshold (~$270,000).

Washington Safe Harbor & Estimated Tax Vouchers (None for wage vests (Federal Form 1040-ES only; WA DOR My DOR portal for 7% Capital Gains Excise Tax))

No Washington state income tax quarterly estimated vouchers are required at vest; however, federal Form 1040-ES quarterly payments remain mandatory to cover the 13%–15% federal supplemental spread.

Multi-State Relocation & Nonresident Sourcing Rules in Washington

Relocating to Washington prior to an RSU vest eliminates state tax on post-relocation service periods, but former residents of California, New York, or Massachusetts remain liable to their departure state for the prorated workday fraction earned prior to establishing Washington domicile.

Employer Stock Plan Specifics: Stripe (Carta / Morgan Stanley at Work)

Stripe has pioneered ongoing employee liquidity for a late-stage private company by waiving liquidity triggers on specific RSU cohorts and executing regular company-sponsored tender offers to cover tax obligations and provide secondary liquidity. However, when Stripe net-settles shares at vest or executes a tender offer, payroll withholding still defaults to the 22% federal statutory rate—leaving a 10% to 15% cash tax gap on illiquid private equity.

Withholding Election Guidance: Unlike public company employees who can log into Schwab or Fidelity any day and sell extra shares on the open market to pay the IRS in April, Stripe employees hold private shares that cannot be traded outside designated tender offer windows. Therefore, when a tender offer window opens on Carta / Morgan Stanley at Work, you must sell enough secondary shares (or set aside cash from your base salary) to cover the 13%–15% federal and state underwithholding gap.
