Oregon Real Estate Transfer Tax Calculator

Oregon bans real estate transfer taxes by statute in every county except one: Washington County, in the Portland suburbs, is grandfathered in at a rate of roughly 0.1%, a holdover from before the statewide ban took effect that no other Oregon county or city may replicate. Everywhere else in Oregon, from Portland's Multnomah County to the coast to eastern Oregon, the transfer tax computed here is $0.00.

That single-county exception makes Oregon's situation structurally different from a true no-tax state like Idaho or Montana, where nothing exists anywhere in the state; Oregon instead has an active statewide prohibition with one legally preserved carve-out. This calculator applies Oregon's general no-tax rule as its default, which is accurate for the overwhelming majority of the state; a Washington County transaction specifically should account for that county's small grandfathered rate instead.

Oregon pairs this near-total absence of a transfer tax with the absence of a state sales tax as well, two revenue sources the state's tax structure largely omits, relying instead more heavily on income tax to fund state government.

Oregon banned local real estate transfer taxes by statute and never enacted a state one. Washington County is grandfathered at roughly 0.1% and is the single exception in the state.

The engine reads Oregon's hasTransferTax: false flag and returns zero without applying a rate. Net proceeds equal the full sale price under the modeled statewide baseline. For a property in Washington County, which covers Beaverton, Hillsboro and Tigard, that grandfathered county tax applies and has to be added to the figure above.

Oregon's statewide answer is a lookup, but the one county exception is worth pricing alongside it.

Step 1 -- The consideration. Contract sale price = $380,000

Step 2 -- The rate-table lookup. Oregon's entry returns hasTransferTax: false. No rate is read and no multiplication runs.

Step 3 -- Transfer tax due, statewide baseline. $0.00

Step 4 -- Net proceeds. $380,000.00 - $0.00 = $380,000.00

Step 5 -- The effective rate. $0.00 / $380,000 = 0.000%

Step 6 -- The luxury scenario, $1,500,000. Same statewide result: $0.00 due, $1,500,000.00 net, 0.000% effective.

Oregon's zero is legislated rather than merely unenacted: state law bars counties and cities from imposing a real estate transfer tax, with Washington County grandfathered because its roughly 0.1% tax predated the ban. That single exception sits outside the statewide baseline the steps above model, so a Beaverton or Hillsboro transaction should add approximately 0.1% of the price, about $380 on the Step 1 sale and about $1,500 on the Step 6 one, to whatever the calculator reports. Everywhere else in Oregon, including Portland proper, the statewide zero is the complete answer. Oregon also has no sales tax, so a buyer relocating from Washington, where the state and local REET on the same $1,500,000 sale runs past $22,000, will find the closing statement noticeably shorter on the Oregon side of the Columbia.

Oregon banned local real estate transfer taxes by statute and levies none at the state level, so the engine's table flags the state with a transfer tax flag of false and a rate of zero. Every row of the price sweep therefore returns the same figure, and the useful work here is proving it and naming what the zero leaves out.

The sweep returns nothing at every price. At the $380,000 baseline the transfer tax is $0.00 and net proceeds are the full $380,000.00. At $390,000 the tax is $0.00 and proceeds are $390,000.00. At $1,500,000 the tax is $0.00 and proceeds are $1,500,000.00. The effective rate output reads 0.000% at every one of those prices and the mansion tax output reads $0.00.

The marginal cost of the next unit is $0.00. Each additional $10,000 of Oregon sale price adds nothing to the transfer tax line. There is no consideration anywhere in this calculator's accepted range, from $10,000 to $100,000,000, at which the Oregon figure becomes positive.

The reverse question has no answer, and that is the answer. On a taxing state's page the useful inversion is the sale price behind a given fee. In Oregon every price maps to the same $0.00, so net proceeds before the other closing costs simply equal the contract price. A seller modelling proceeds can drop the transfer tax line from the spreadsheet entirely.

Right method against wrong method, and Oregon has a genuine exception. Washington County was grandfathered when the statewide ban took effect and continues to levy a transfer tax of roughly 0.1% on conveyances within it. This calculator holds one statewide rate of zero and no county table, so a Hillsboro or Beaverton sale that does carry a real charge still returns $0.00 here. That is the only circumstance in which the zero on this page is wrong, and it is wrong for a substantial share of Portland-metro transactions.

What an Oregon closing still costs. County recording fees are charged per instrument and per page with no relation to sale price, and appear nowhere above. Neither do title insurance premiums, escrow and settlement fees, or the real estate commission. Oregon also requires most sellers of Oregon real property who are non-residents to have tax withheld at closing against their eventual Oregon income tax on the gain; that withholding is an income tax mechanism, not a transfer tax, and no figure on this page computes it.

• Washington County's grandfathered local transfer tax. This is the sole exception to Oregon's statewide zero-tax status, running at roughly 0.1% of the sale price, and it is not included in this calculator's statewide baseline.
• County recording fees. Oregon county clerks charge a flat fee per document to record the deed, unrelated to sale price and not a transfer tax.
• Title insurance and escrow fees. Oregon closings customarily go through an escrow company, and those fees are set separately from any transfer tax.
• Real estate commissions. Agent commissions are negotiated separately and typically represent the largest single cost at closing.
• Property tax proration. Buyers and sellers typically prorate the current year's property tax at closing, which this calculator does not compute.

• Assuming Oregon has no exceptions at all. Washington County is a real, grandfathered exception, and transactions there should account for its roughly 0.1% local tax.
• Assuming other Oregon counties could adopt a similar tax. State law specifically bans new local transfer taxes outside of Washington County's pre-existing, grandfathered levy.
• Confusing the transfer tax ban with a property tax exemption. Oregon still assesses annual property tax on real estate; the ban applies only to one-time transfer taxes at conveyance.
• Overlooking county recording fees as if they were a transfer tax. Recording fees are real but flat and unrelated to sale price.
• Assuming a Portland-area sale automatically falls in Washington County. The Portland metro spans Multnomah, Clackamas, and Washington counties; only Washington County carries the local transfer tax.
