- Washington state lawmakers propose a new high-income surcharge to fund schools and public services.
- The current legislative session ends March 12, 2026, setting a tight window for approval.
- Proposed legislation includes targeted sales tax relief and credits for working families and small businesses.
📅 Deadline Alert: Washington’s 60‑day legislative session ends March 12, 2026. If Senate Bill 6346 (and its House companion) is going to move this year, key votes must happen before then. For most taxpayers, there is no immediate payment due, but the window to influence the bill is short.
Hundreds of supporters gathered on the Capitol steps in Olympia this week to push for what backers call the “Millionaires Tax.” The rally matters because Washington does not have a broad personal income tax. Any high‑income surcharge proposal is both a policy shift and a legal‑political test.
This is still proposed legislation, not a tax you can file today. Whether it becomes law depends on the remaining legislative calendar, the Governor’s signature, and likely court or ballot challenges. Supporters argue Washington’s overall tax structure is regressive, and they frame this proposal as a way to fund schools and health care while pairing it with targeted relief.
Deadline summary (what to watch now vs. later)
| Event | Date | Who it affects | What happens if missed |

Senate Bill 6346: what the proposal would do
The proposal is moving as a pair: Senate Bill 6346 and House Bill 2724, backed by Senate Majority Leader Jamie Pedersen and House Majority Leader Joe Fitzgibbon. it creates a high‑income surcharge aimed at a small share of households. It is not designed to touch people at ordinary income levels.
A few mechanics matter for high earners, including immigrants who are new to Washington:
- Income above a high threshold only. The tax is drafted to apply only once household income exceeds a very high level.
- Washington‑sourced concept. Sourcing rules are central for people who earn income across states. This includes remote workers, executives with multi‑state roles, and investors.
- Credits to reduce double taxation. The bill describes a credit approach where overlapping state taxes may apply. The goal is to reduce “taxed twice” outcomes in common scenarios.
- Start date and first payments. The structure contemplates an effective date first, with initial payments later. In practice, that means a long runway for planning, and no immediate filing for 2026 federal returns.
For immigrants and visa holders, remember this split: federal residency determines whether you file Form 1040‑NR or Form 1040. That is governed by IRS rules in Publication 519 (U.S. Tax Guide for Aliens). Washington’s proposal does not change those federal rules.
⚠️ Warning: Don’t confuse a proposed Washington surcharge with your actual 2026 federal filing status. If you meet the Substantial Presence Test, you may owe U.S. tax on worldwide income even if Washington has no broad income tax.
Where the revenue would go, plus linked relief items
Supporters sell the Millionaires Tax as “fund schools and services, pair it with relief.” The bill language describes a split between major state priorities and county public defense.
The relief pieces are politically tied to the new tax, and they are written to be easy to explain:
- A sales‑tax change on certain grooming and hygiene items, aimed at everyday consumer costs.
- Business & Occupation (B&O) changes, including a small‑business focus tied to gross receipts. This is especially relevant for immigrants who run salons, consulting practices, restaurants, or other closely held businesses.
- An expansion of the Working Families Tax Credit, which is a state credit conceptually similar to an earned income credit.
These relief items do not replace federal credits. For federal credits, immigrants typically look to rules in Publication 17 and, for treaty positions, Publication 901 (U.S. Tax Treaties).
Rally messaging in Olympia
The Olympia crowd included union members, educators, retirees, and Democratic lawmakers. The core message was that Washington’s system should be more progressive, and that top earners should fund public priorities.
House Speaker Laurie Jinkins told attendees she believes the bill can reach the Governor. Rep. Natasha Hill highlighted school funding and described it as a power and priorities issue. The through‑line was fairness plus visible relief for families.
Opposition and likely flashpoints
Opponents focus on three claims:
- Pass‑through business exposure. S corporations and LLC owners worry the definition of taxable income can hit business owners unevenly, especially in high‑income years.
- Jobs and competitiveness. Critics argue high earners and founders may shift activity out of state.
- Legal and political risk. Washington has a history of income‑tax fights. Even if enacted, challenges and repeal attempts are realistic.
Governor Bob Ferguson has voiced support, and proponents argue the relief provisions strengthen public backing.
What happens next, and how immigrants should prepare
Legislators have only a few weeks left in session. If the bills do not move before March 12, 2026, the timeline can slip.
If a version becomes law, practical tax administration would come later, likely with Washington Department of Revenue guidance. Immigrants with cross‑border finances should prepare now by keeping clean records of:
- Where services were performed (for wage and self‑employment sourcing questions)
- Business entity ownership and distributions (LLC/S‑corp K‑1s)
- Investment income detail (brokerage statements, capital gains schedules)
Also keep up with federal reporting. If you are a U.S. tax resident under Publication 519, you may need FBAR (FinCEN 114) and Form 8938 for foreign accounts, even if Washington’s state rules are still in flux. Official IRS international guidance is at irs.gov/individuals/international-taxpayers, and forms are at irs.gov/forms-pubs.
Action items (this month):
- Track SB 6346 / HB 2724 status on the Washington State Legislature website.
- If you run an LLC or S‑corp, ask your CPA how Washington sourcing could be measured for your income.
- For tax year 2026 (filed in 2027), confirm whether you’ll file Form 1040 or 1040‑NR, and calendar the federal and FBAR deadlines above.
