Oregon versus Washington, for somebody buying a house

The commuter question

Here's the thing that surprises almost everybody. Whether you owe Oregon income tax depends on where your body is when you do your job, not on where your employer's office is. Once you understand that, the three cases fall out cleanly.

That middle row is the most valuable line on this page, and it's the reason a remote worker's Vancouver math looks completely different from a five-days-in-the-office commuter's. Same house, same salary, very different outcome.

The residency definitions that decide which return you file

• Nonresident: domiciled outside Oregon, and either you keep no permanent home in Oregon or you spent 200 days or fewer in Oregon during the year.
• Resident: domiciled in Oregon, which Oregon describes as "the center of your financial, social, and family life is in Oregon."

And then the trap, which catches more people than you'd think. Keep a permanent home in Oregon and spend more than 200 days there and you can be taxed as a full-year Oregon resident, even if you're domiciled in Washington, unless the time was for a temporary purpose. So if you're moving to Vancouver but keeping the Portland house, whether as a rental or for a family member or just because you haven't sold it yet, that's a conversation to have with your CPA before the year starts, not after it ends.

The local taxes reach across the river too

Two more pieces that catch Vancouver residents by surprise:

• Multnomah County's Preschool for All tax applies to nonresidents on income sourced within the county. So a Vancouver resident working in a downtown Portland office owes it on the Multnomah-sourced portion of their income, on top of the Oregon state tax.
• The Metro Supportive Housing Services tax explicitly excludes remote work performed outside the district for a Metro-area employer. Same logic as the Oregon nonresident rule, pointing the same direction, which is a nice piece of consistency in a system that doesn't always have it.

What a Portland household actually pays

Oregon's income tax doesn't arrive as one number. It arrives as a stack, and the stack is what makes the comparison interesting.

Oregon state income tax

The top marginal rate is 9.9%, confirmed in Oregon's 2026 withholding tax formulas. It applies above roughly $125,000 of taxable income for single filers and $250,000 for joint filers, and those two thresholds are set in statute and don't index.

I'm deliberately not publishing the full 2026 bracket chart here. The lowest bracket boundaries index annually and I couldn't confirm the 2026 dollar figures from a source I trust, so rather than publish last year's numbers as if they were current, get the current chart from Oregon Publication OR-17 or from your CPA. The top rate is the number that matters for this comparison anyway.

Multnomah County Preschool for All

City of Portland residents in Multnomah County pay this one, and there's a rate increase coming.

That's a 0.8 percentage-point increase taking effect January 1, 2027, with no sunset provision on the tax. It applies to residents on full Oregon taxable income and to nonresidents on income sourced within the county. Social Security and PERS income are exempt, which matters a lot if you're retired or close to it.

Metro Supportive Housing Services

1% on taxable income above the threshold. The thresholds were $125,000 single and $200,000 joint for tax years 2021 through 2025, and from 2026 they index annually, landing at $128,000 single and $205,000 joint for 2026.

Important geography: the Metro district covers roughly the urbanized parts of Multnomah, Washington and Clackamas counties, and it does not follow county lines. Parts of all three counties sit outside it. So don't tell a Washington County buyer they automatically owe this, and check the specific address.

Portland Arts Tax

$35 a year, per City of Portland resident aged 18 and over, with $1,000 or more of annual income, in a household above the federal poverty level. It's flat rather than a percentage, it's due with your federal return (generally April 15), and there are no extensions. You have to file even if you're exempt. There's a $15 penalty the day after the deadline and another $20 if it's still unpaid six months later. City of Portland residents only, so not Beaverton, Hillsboro, Lake Oswego or Vancouver.

Stack it up

Take a Portland household filing jointly at, say, $450,000. At the top margin they're looking at roughly 9.9% Oregon plus 3.0% Preschool for All plus 1.0% Metro, which is about 13.9%, rising toward 14.7% in 2027 as Preschool for All steps up. Plus $35 per adult.

The identical household living in Vancouver and working remotely or for a Washington employer: 0%.

Sales tax, and what the arbitrage is really worth

The April 2026 increase added a 0.1% housing and related services tax plus a 0.1% law enforcement tax. Vancouver already had the housing component, so only the law enforcement piece was new there. Other Clark County cities including Camas, Battle Ground, Ridgefield and Washougal have different rates, so confirm the specific city rather than assuming Vancouver's applies.

Now, the famous arbitrage: live in Vancouver for no income tax, shop in Portland for no sales tax. Is it real? Yes, and it's narrower than people think. Washington residents no longer get a point-of-sale exemption on most Washington purchases, and Oregon purchases technically trigger Washington use tax. So the savings are real on the big deliberate purchases you'd drive for and much thinner on daily spending. I'd rather tell you that than let you build a budget on a bigger number.

Two property tax systems, running in opposite directions

This is the part where people assume one state is simply cheaper, and neither one is. They're structurally different, and the difference shows up in different ways.

Oregon: the rate is limited

Every Oregon property carries a Real Market Value (what it would sell for) and a Maximum Assessed Value (a synthetic number that grows at most 3% a year). You're taxed on the lower of the two. Measure 50 set the starting Maximum Assessed Value in 1997 at 90% of each property's 1995–96 value, and it's grown at no more than 3% annually ever since while market values grew much faster.

A sale does not reset it. New construction, additions, remodels and subdivisions do. Which is why two identical houses on the same Portland street can pay two or three times different tax on the same market value, depending on when each was last built or remodeled. Measure 5 caps rates at $5.00 per $1,000 of real market value for education and $10.00 for general government, and tax above those caps gets "compressed," which cost $189 million statewide, or 1.9% of tax extended, in FY 2024-25.

FY 2024-25 figures, countywide averages across every property type including commercial. Typical, not a quote. For a specific address, the county assessor's parcel record is the only real answer.

Washington: the levy is limited

Assessed value equals 100% of true and fair market value, revalued annually, with no cap. Each taxing district adopts a budget, and the assessor back-solves the rate by dividing the levy by the district's total assessed value. The 1% limit caps each district's total levy revenue growth at 1% a year. It does not cap your bill.

So rising values don't automatically raise taxes. If every property in a district doubles, the rate roughly halves and the levy is unchanged. What moves your individual bill is how your property's value changed relative to your neighbors'. Washington's Department of Revenue publishes a worked example with three homes in one city under the same 1% limit where one bill fell 3.39% and another rose 5.39% in the same year.

That fourth row is the memorable one. Washington's system is far more equitable between neighbors. Oregon's is far more predictable year to year for the individual owner. Neither is simply cheaper, and anybody telling you otherwise is selling something.

One Oregon quirk worth knowing if you're worried about a downturn: a falling market usually doesn't lower an Oregon tax bill. Clackamas County puts it directly, that "a reduction in RMV will not mean a reduction in taxes unless the RMV is reduced below the AV." With assessed values near half of market value across much of the metro, prices would have to fall by half before your bill moved.

Washington's capital gains tax exempts real estate

This one comes up in almost every Vancouver conversation and it's widely misunderstood, so here it is plainly.

Washington taxes capital gains at 7% on Washington capital gains up to $1 million, and 9.9% on gains above $1 million (a 2.9% surcharge stacked on the 7%). The tiered structure began with tax year 2025, and the first affected returns were due April 15, 2026.

But real estate is exempt. The tax reaches long-term gains on stocks, bonds and business interests. It does not reach the gain on the sale of real property. So the objection I hear constantly, that moving to Washington means paying tax when you sell the house, has the facts backwards.

There's also a per-filer standard deduction that's inflation-indexed, and I'm not publishing the amount because I couldn't confirm the current figure. Get it from the Washington Department of Revenue or from your CPA. Federal capital gains rules apply either way, and the federal primary-residence exclusion is a separate question entirely, so that's a CPA conversation too.

Estate tax, the one that quietly flips the answer

For a lot of buyers this is a footnote. For an estate-planning-aware buyer it frequently outweighs the income tax question entirely, and it points the opposite way from what people expect.

What that means in practice: a $2.5 million estate is fully exposed in Oregon and fully exempt in Washington. Oregon's exclusion is one of the lowest in the country, it hasn't been indexed, and a Portland house plus a retirement account plus a life insurance policy adds up faster than people expect. So if you're 60 and choosing sides of the river, this may matter more to your family than the income tax rate does.

What all of it means for your loan

Here's the practical layer, which is the part I actually do for a living.

The loan limits are identical on both sides

Clark, Multnomah, Washington and Clackamas counties all sit at the $832,750 2026 conforming baseline, and all four share the $701,500 FHA limit, because they're all inside the Portland-Vancouver-Hillsboro OR-WA MSA and HUD sets FHA limits by metro area. So the loan limit is not a reason to pick a side of the river.

The exception is if you're arriving from Puget Sound. King, Pierce and Snohomish counties are at $1,063,750, so moving down here costs you about $231,000 of agency headroom, and a loan that was routine up there can be jumbo down here. More on that on the Vancouver page.

Down payment assistance does not port

Cross the river and you lose Oregon Housing and Community Services and Portland Housing Bureau eligibility, and gain Washington State Housing Finance Commission eligibility. They're separate program sets with separate rules, income limits and administering organizations. If you're shopping both sides, know which set you're in before you write an offer, because it changes what you need to have in place. All of these are budgeted programs where funds run out, so confirm current status with the organization administering the program rather than with any website. The Portland and Vancouver pages each list what's available on that side.

The income tax difference is borrowing capacity

Here's the part that's specifically a mortgage observation rather than a tax one. Debt-to-income ratios are calculated on gross income, so state income tax doesn't change what you qualify for on paper. But it absolutely changes what you can afford in practice, because the money that goes to Oregon is money that isn't available for the payment. Two identical borrowers, one in Portland and one working remotely from Vancouver, qualify for the same loan and live very differently inside it.

And somebody has to be able to quote both

I'm personally licensed in Oregon and Washington, plus California, Arizona and Idaho. Most Portland loan officers are licensed on one side of the river only, which is why this comparison so rarely gets done honestly for the person making the decision. Send me a house on each side and I'll price both, with real assessor figures rather than a percentage of the purchase price.

Then run the numbers yourself: the affordability calculator and the rent-versus-buy calculator, and the weekly market update for what's moving rates this week.

Common questions

I live in Vancouver and commute to a Portland office. Do I pay Oregon income tax?

Yes. Wages for work physically performed in Oregon are Oregon-source income, you file an Oregon nonresident return, and because Washington has no income tax there's no credit to offset it. It's a straight additional cost, and it's the single biggest thing people get wrong about moving to Vancouver.

What if I work from home in Vancouver?

Then you don't owe Oregon tax on those days. Work performed physically in Washington is Washington-source income. If you're hybrid, you apportion by days, and Oregon tells nonresidents to get a signed employer statement verifying the number of days worked in Oregon. Start that documentation in January.

I live in Portland and work in Vancouver. Do I save anything?

No. Oregon residents are taxed on all income from all sources, wherever earned. Your employer being in Washington changes nothing, and there's no other-state credit to claim because Washington doesn't tax the income.

Does Washington tax the gain when I sell my house?

No. Real estate is exempt from Washington's capital gains tax. That tax reaches long-term gains on stocks, bonds and business interests. Federal rules on your gain are a separate question, and one for your CPA.

So is Vancouver cheaper overall?

It depends almost entirely on where you physically work, and secondarily on your income level and your estate situation. Remote or Washington-employed at a high income, the case is strong. Driving to a Portland office five days a week, you're paying Oregon income tax and Washington sales tax, which is the worst combination available. Sit down with a CPA and run it both ways before you commit to a side.

Which state has lower property taxes?

Wrong question, honestly. They're different systems, not different prices. Oregon caps how fast your assessed value can grow, which makes your bill predictable but makes neighbors' bills very unequal. Washington assesses at full market value every year and caps the levy instead, which makes neighbors equal and your own bill move with relative value. Compare the two specific houses, not the two states.
