What this calculator does

Washington's real estate excise tax is paid when property sells. The state portion is graduated like income-tax brackets, and Seattle adds 0.5%. Washington's real estate excise tax (REET) is graduated: 1.1% up to $525,000, 1.28% to $1,525,000, 2.75% to $3,025,000 and 3% above for 2023–2026, plus Seattle's 0.5% local REET. The seller customarily pays it.

How to use it

  1. Enter the sale price.
  2. Read the state tax by bracket, the local tax and the total.

The formula

State REET = 1.1% of the first $525,000 + 1.28% of the part to $1,525,000 + 2.75% of the part to $3,025,000 + 3% above (2023–2026). Local REET = price × 0.5%.

Worked example

Using the default inputs shown in the calculator above:

PortionTax
State portion at 1.10% on $525,000$5,775
State portion at 1.28% on $375,000$4,800
Seattle local REET (0.5%)$4,500
Total REET$15,075

Total real estate excise tax: $15,075. Effective rate 1.68% · usually paid by the seller.

Washington's REET works like income-tax brackets: each slice of the price is taxed at its own rate, so only the part above $525,000 pays more than 1.1%. Seattle adds a flat 0.5% on the whole price.

Thresholds are adjusted every four years; from 01/01/2027 they rise to $551,000, $1,551,000 and $3,051,000. The seller customarily pays, and the tax is collected by the county treasurer when the excise tax affidavit is filed.

REET at common Seattle prices

Seattle prices range from condos under $600,000 to houses well above $1.5 million, and the graduated state brackets make the effective rate climb as the price rises. The table adds Seattle’s 0.5% local REET to the state amount for each price.

$750,000$8,655$3,750$12,4051.65%
$1,000,000$11,855$5,000$16,8551.69%
$1,500,000$18,255$7,500$25,7551.72%
$2,000,000$31,638$10,000$41,6382.08%
$3,000,000$59,138$15,000$74,1382.47%
$4,000,000$89,075$20,000$109,0752.73%

A seller at $750,000 pays about 1.65% in total, while a seller at $3,000,000 pays about 2.47%. Because only the slice of the price inside each bracket pays that bracket’s rate, there is no sudden jump when a price crosses a threshold: an extra $10,000 above $1,525,000 adds only $275 of state tax.

Common mistakes and tips

  • Applying 1.28% to the whole price — only the part above $525,000.
  • Forgetting the 0.5% local REET.
  • Using the 2027 thresholds for a 2026 sale.
  • Missing exemptions, such as certain transfers between family members.
