Real Estate Property Transfers

Please note: Any transfers of real property done after January 1st, 2020 are subject to the graduated real estate excise tax rate structure, below, with the exception of land classified as agricultural/timberland. Those are calculated at a flat rate of 1.28%.

A Real Estate Excise Tax (REET) Affidavit must be completed and accompany any legal document transferring ownership of real property. The affidavit will not be accepted by the Treasurer’s office unless all areas 1-7 are fully completed. The affidavit must bear original signatures.

Excise affidavits must have a valid, deliverable mailing address. Street addresses for properties in the following cities/towns will cause an excise affidavit to be rejected: Snoqualmie Pass, Roslyn, Ronald, Easton, South Cle Elum, Kittitas and Vantage. All these cities/towns require delivery to a post office box.

Mobile homes require a separate affidavit for change of ownership.

Special Exemptions may require the use of a Supplemental Statement as well.
