Washington County's transfer tax: the only one in Oregon, and what it costs you

Buy a house in Beaverton, Tigard or Hillsboro and there's a line on your settlement statement that doesn't exist anywhere else in Oregon. It's small, it's real, and almost nobody sees it coming.

Washington County charges a real estate transfer tax. It is the only county in the state that does, and the reason is a quirk of timing rather than policy.

What it costs

One dollar per thousand dollars of the selling price. That is the county's own wording.

On a $540,000 sale, that's $540. On an $800,000 sale, $800. It scales cleanly, which at least makes it easy to budget for once you know it exists.

The county's position on who pays is refreshingly blunt: liability for the tax is between the purchaser and the seller. There is no statutory allocation. It's a negotiated item like any other, and in practice it usually follows local custom and whatever the purchase agreement says — which means it's worth checking what your agreement says rather than assuming.

There's an exemption path for low-value transfers, with its own form for transactions under $13,999, plus exemptions for categories that aren't really market sales — transfers between spouses by court order, transfers by gift, devise or inheritance, instruments recorded solely for security purposes.

Why only this county

In 1997 Oregon banned local real estate transfer taxes. ORS 306.815 says a city, county, district or other political subdivision "shall not impose... a tax or fee upon the transfer of a fee estate in real property."

But the statute grandfathers anything already running: the prohibition "does not apply to any tax if the ordinance or other law imposing the tax is in effect and operative on March 31, 1997."

Washington County's was. Nobody else's was. So the map of Oregon transfer taxes is one county, frozen in place by a date.

That's the whole explanation. It isn't that Washington County decided to charge more for housing. It's that it happened to already be charging when the door closed.

What this means if you're buying across the county line

Portland-metro buyers shop across county lines constantly — Multnomah, Washington and Clackamas all sit inside a reasonable commute of each other, and the same budget buys different things in each.

The transfer tax shouldn't change that decision. At a dollar per thousand it is a rounding error next to the price difference between two neighborhoods, and anyone telling you to avoid a county over it is selling you something.

What it should change is your closing-cost estimate. If you've been quoted closing costs for a Multnomah County purchase and you're now writing in Washington County, that estimate is light by the tax. Ask your escrow officer for a revised figure rather than discovering it on the settlement statement.

Where this fits

The transfer tax is a transaction cost — money that moves once, at closing. That's a different question from what the house costs you every month afterward, which is where most buyers underestimate.
