Washington State Income Tax Filing

Washington income tax at a glance

Washington levies no income tax on wages or salaries, which is why there is no annual state return and nothing withheld for the state from your paycheck. For most people working in Seattle or Bellevue that is the end of it. There is, however, one important exception that catches exactly the population the region attracts: Washington taxes long-term capital gains above a standard deduction of $278,000 at 7%, rising to 9% on the portion above $1 million. Wages are outside it, and so is real estate, but a large stock sale is not — and in a technology-heavy job market where compensation arrives as RSUs, a single vest-and-sell decision can put someone over a threshold they did not know existed. Distinguishing the sale of long-held shares from ordinary wage income delivered as stock is the part worth getting right before you sell rather than after.

Washington tax rates on capital gains

These rates apply only to long-term capital gains above the standard deduction of $278,000 per return. Wages and salaries are not taxed by Washington at all.

Rates and thresholds as of January 1, 2026. State legislatures change these mid-year and several states index brackets annually — check against Washington State Department of Revenue before relying on a figure.

What to watch out for in Washington

• The capital gains tax applies to long-term gains only, and the $278,000 standard deduction is per return rather than per asset. Below it, no Washington tax and no return.
• Real estate sales are excluded from the Washington capital gains tax, as are distributions from retirement accounts and certain qualifying business sales. It is a much narrower tax than "Washington taxes capital gains" suggests.
• RSUs are wage income when they vest, not capital gains — so the vest itself is outside this tax. It is the later sale of the shares, and the gain since vesting, that can fall inside it.
• Washington funds itself largely through sales tax and the business and occupation tax on gross receipts. Anyone running a business in the state has a B&O obligation regardless of profitability, which is a genuinely different model from an income tax.

Your Bengaluru flat is outside the Washington capital gains tax. Your Indian mutual funds may not be

Washington is the best state on this list for anyone with Indian income, with one specific exception that lands squarely on this audience. Because there is no wage income tax, there is also no state tax on your NRO interest, your Indian rental income or your Indian salary before you arrived. None of it enters a Washington return, because for wage earners there is no Washington return.

The exception is the capital gains excise tax, and the distinction that matters is the type of asset rather than where it sits. Real estate is excluded from the tax outright, so selling a flat in Bengaluru or Pune is outside it however large the gain. Financial assets are not excluded, and for intangible assets the gain is allocated to Washington based on the seller being domiciled here. So a Washington-domiciled H-1B holder selling a long-held block of Indian mutual funds or Indian listed shares is in a different position from the same person selling Indian property.

Two things soften it. The standard deduction is substantial and applies per return rather than per asset, so ordinary disposals fall well below it and generate no tax and no filing. And Washington law provides a credit against the tax for income or excise tax legally paid to another taxing jurisdiction on capital gains derived from assets within that jurisdiction — which on its face can reach Indian capital gains tax on an Indian asset. That is a favourable reading rather than a settled one for this specific case, so it is worth confirming with the Department of Revenue on your facts before relying on it.

The federal side is untouched and is usually the larger problem anyway. Indian mutual funds are almost always PFICs, with their own reporting form and a default regime designed to be unattractive, and that applies identically whether you live in Seattle or San Jose. Washington changes the state layer, not the PFIC analysis.

The order of operations matters if you are holding Indian mutual funds and considering a sale. The PFIC position should be worked out first, because it drives the federal outcome and is the more complicated of the two. The Washington question is then a threshold test on top of it.

Go deeper on the India side

These guides cover the federal treatment of Indian income and assets in detail. They apply wherever you live in the US — Washington sits on top of them.

• Indian Mutual Funds and the PFIC ProblemPFIC status turns on the US income and asset tests applied to the fund — tests a pooled vehicle holding securities will often meet. What that means for your SIPs, why the default regime is the punitive one, why the QEF election is usually closed to you, and how many Form 8621s you may owe.
• FBAR and Indian Bank AccountsWhich Indian accounts are reportable on FinCEN Form 114 — savings, NRE, NRO, FCNR, fixed deposits, PPF, EPF, demat — how the $10,000 aggregate threshold really works, and why many F-1 students owe nothing at all.
• Form 8938 and FATCA ReportingFiling an FBAR does not satisfy Form 8938, and neither form is a subset of the other. The thresholds, and exactly which Indian holdings each one catches — including the ones only Form 8938 reaches.
• The Foreign Tax Credit and Form 1116The mechanism that actually stops you being taxed twice — and it does not work evenly. NRE interest is fully taxable in the US with no credit at all, because India exempted it. Plus the April-March year mismatch nobody warns you about.
• Streamlined Filing ComplianceYou have just worked out that your Indian accounts should have been reported for years. There are two procedures, one costs 5% of everything you hold and the other costs nothing — and which one you get depends on dates that are moving.
