This comes up in almost every conversation about crossing the river, and it is the single most confidently wrong topic in Portland real estate. I am licensed in both states and I sell on both sides, so I have no dog in the fight. Here is the honest version.
Start with what is simply true
Washington has no state income tax. Oregon does. Oregon has no state sales tax. Washington does. That is the entire folklore, and it is where most conversations stop.
It stops too early, because it describes two states rather than your actual life.
The part everyone skips: where you work
Living in Vancouver does not, by itself, mean you stop paying Oregon income tax. Income earned from work performed in Oregon is generally taxable by Oregon, which means a Vancouver resident commuting to a Portland job typically files an Oregon non-resident return on those wages.
What does change is everything that is not Oregon-source: investment income, retirement income, a business you run from home, and work you actually perform in Washington. For some households that is most of the picture. For others it is almost none of it. That is the whole ballgame, and it is completely person-specific.
And the local taxes on top
Portland has two local income taxes that people forget when they run these numbers: the Metro Supportive Housing Services tax and the Multnomah County Preschool for All tax. Both are worth understanding because both are jurisdiction-based, not just residence-based.
The city's own guidance says they are owed by people who live in the jurisdiction, work in it, or have income from sources in it, and that "for non-residents, Metro taxes only your income from Metro sources." For 2026 the thresholds are $128,000 for a single filer and $205,000 filing jointly, indexed annually.
So a Vancouver household with a Portland job can still be inside these. Not always. It depends on income, source and where the work is performed.
Why I stop here
Because the next sentence would be advice, and I am a broker, not your accountant. Anyone who gives you a confident blanket answer to this question is either selling you a house across the river or has not thought about it carefully.
What I will do is tell you plainly that this is a real variable worth an hour of a professional's time before you choose a side of the river, not after. An hour with a CPA is cheap next to a house bought on a misunderstanding.
The rest of the comparison
Taxes are one input and rarely the deciding one. The others: what your money buys in housing, the bridge and what it does to your day, and whether the community fits. Those are the ones I can actually help with.
If you are weighing it, the Vancouver guide and the market reports on both sides are the honest place to start. I can show and write on either side of the river, so there is no version of this where I steer you.
Rules and thresholds checked against the City of Portland Revenue Division and Oregon Department of Revenue guidance in August 2026. This is general information, not tax advice, and it changes. Confirm with your own accountant.
Quick answers.
If I live in Vancouver and work in Portland, do I pay Oregon income tax?
Generally yes, on the income earned from work performed in Oregon, filed as an Oregon non-resident. What you would not owe Oregon tax on is income that is not Oregon-source, such as investment income, retirement income, or work you genuinely perform in Washington. Confirm the specifics with your accountant.
Do Washington residents pay the Portland Metro and Multnomah County taxes?
They can. Both are owed by people who live in, work in, or have income sourced from the jurisdiction, and non-residents are taxed on jurisdiction-source income. For 2026 the thresholds are $128,000 single and $205,000 joint. Whether you are inside them depends on your income and where it is earned.
Can you help me buy on both sides of the river?
Yes. I am licensed in Oregon and Washington, so I can show and write in either state, and a lot of my clients look at both before deciding.
