Washington vs. Oregon Taxes 2026:
What Just Changed — And What It Means For You

Washington doesn't have a corporate income tax. Instead it uses what's called the Business and Occupation tax — a gross receipts tax that businesses pay on their total revenue. Most states don't have anything like it.

The rates on service-based businesses — think consultants, agencies, tech companies, healthcare services, anything in the service sector — run from 1.5% to 2.1% depending on the type of business. Those rates went up in 2026, with service businesses seeing increases across the board. On top of that, larger companies with over $250 million in Washington revenue face an additional 0.5% surcharge.

If you do own a small business or are self-employed in a service field, this is a direct cost you'll feel. The B&O tax applies to gross revenue — not profit — which means even if your margins are thin, you're still paying.

Washington expanded what counts as a taxable service under sales tax. New categories now include things like custom software development, website services, advertising, IT services, and staffing services.

This matters more for business owners than for families and retirees — but it's worth knowing if you hire any of these services for personal use, like a web designer for a small side business.

The gas tax increase in Washington's 2025 package was significant. Washington's base gas tax went up 12%, bringing the total state rate to 55.4¢ per gallon — already one of the highest in the country. On top of that, Washington’s carbon pricing program (CCA) adds a surcharge of roughly 40–60¢ per gallon as companies pass their emissions costs to consumers. That means the real cost at the pump can be well over $1 per gallon more than Oregon.

For the average driver doing 12,000 to 15,000 miles a year, the current difference between Washington and Oregon gas taxes costs you roughly $100 to $150 a year. Not the biggest line item — but with the automatic annual increases, it'll grow over time.

And if you drive or plan to drive an electric vehicle, Washington's road usage charge — a per-mile tax to replace gas tax revenue as EVs take over — is coming. EVs and hybrids will pay around 2.5 cents per mile starting in 2026. At 15,000 miles a year, that's about $375 annually. Oregon does not yet have an equivalent mandatory program.

Washington's capital gains tax is worth understanding clearly, because there's a lot of confusion about who it actually affects. Here's the structure:

Washington taxes long-term capital gains at 7%, but the first $278,000 in gains is completely exempt each year. Primary home sales are fully exempt from capital gains tax, so if you sell your primary home, you generally owe nothing. For many middle-class homeowners, that exemption covers the sale entirely.

Exemption for Real Estate: The Washington state capital gains tax—a 7% tax on long-term gains exceeding a specific annual amount (e.g.,in 2025)—does not apply to the sale of real estate.

In 2025, Washington added a new upper tier — gains above $1 million are now taxed at 9.9% instead of 7%. That upper tier is more relevant for investment property sales and business sales than for the typical family home.

Oregon taxes capital gains as regular income — no special rate, no separate exemption. Those same gains get taxed at whatever your income tax bracket is — up to 8.75% for most middle-class earners.

Washington's 7% rate with the $278,000 exemption is actually a better deal for most people than Oregon's treatment — even after the 2025 changes.

Washington's estate tax exemption increased to $3 million — good news for most middle-class retirees. But the top rates went up significantly for very large estates in 2025.

For most of my viewers, the higher exemption is actually the more relevant news. Oregon's threshold is still $1 million — meaning a retiree with a paid-off home, retirement accounts, and life insurance can find themselves subject to Oregon's estate tax without ever thinking of themselves as wealthy.

This one went into effect in 2026, and I want to call it out specifically for my retiree viewers because it catches people off guard.

Washington now imposes an 8% luxury tax on vehicles priced over $100,000 — applied to the amount above that threshold. So if you buy a vehicle for $120,000, you owe 8% on the $20,000 above the threshold — that's $1,600 in additional tax on top of the regular sales tax.

💡 Important for retirees and movers: If you’re retiring, moving to Washington, and have a major vehicle purchase in your plans, remember that sales tax is based on the house address where the vehicle is registered. If you buy in Oregon but register the vehicle in Washington, you’ll pay Washington’s sales tax. This is something to consider and potentially time strategically if you’re coming from out of state.

Let me give you the honest bottom-line math for a household earning $130,000 to $150,000 a year — which is what it realistically takes to live comfortably in the Vancouver area.

That's real money. Not the full "zero tax saves you $9,000" headline — but a meaningful, tangible annual difference that compounds over time.

And that's before the cross-river shopping strategy. If your family makes even a handful of major purchases in Oregon each year — a car, appliances, electronics — you can widen that gap further.

Property taxes are broadly comparable between the two states, though Oregon gives you more predictability year over year. Schools vary significantly — do your homework on specific school district boundaries, because that matters a lot for families with kids.

Washington is about as good as it gets for retirees from a state tax standpoint — and the 2025–2026 changes largely don't touch the things that matter most to you.

Oregon exempts Social Security — a genuine positive. But the rest of your retirement income — pension, IRA, 401k — is taxed at up to 8.75% in Oregon. For a retiree pulling $50,000 a year from retirement accounts, that's roughly $3,000 to $4,000 a year going to the state. Every year. For as long as you live there.

Oregon's property tax predictability under Measure 50 is a genuine advantage for retirees on fixed incomes — you know roughly what your property tax bill is going to be, year over year. Washington's levy system can create more variability.

But on the overall picture, most financial advisors working with retirees in this region will tell you Washington is the more tax-favorable state — particularly if retirement account income makes up a significant portion of your budget.

💡 Other important notes for retirees: The Washington CARES Act + Paid Family Leave benefits ($1,900–$2,200) only apply if you are still working. Retirees do not qualify, so this is not part of your retirement income picture.

Here's context that's helpful for people coming from elsewhere. Both of these states look favorable compared to California, which has a top income tax rate of 13.3% and both high sales tax and high property taxes.

If you're leaving a high-income-tax state like California, Washington will feel like an immediate financial relief on your paycheck. Oregon will feel better than California on income tax for middle incomes — but you'll still have a state income tax.
