Online Forms

Real Estate Excise Tax – See the Department of Revenue website for detailed information about real estate excise tax.

  • Real Estate Excise Tax Affidavits for Real Property and Mobile Homes can be found on Department of Revenue’s website.  This page can be confusing due to the number of forms that must be supported because of REET rate changes, and for single or multiple location transfers.  It is imperative that taxpayers look carefully at the selection to choose the appropriate affidavit that meets the date of sale for their transfer. Choosing the wrong affidavit may cause the tax to be calculated incorrectly and be rejected by the county.  The effective date is noted in red at the top of each form.
  • Real Estate Excise Supplemental Statement – required when claiming certain exemptions from excise tax
  • Lack of Probate Affidavit – to be used as supporting documentation, in accompaniment with a deed to convey ownership of property.
  • WAC 458-61A - Real Estate Excise Tax


Autopay for property tax payments. Submissions for new account enrollments, account changes and cancellation requests must be received by March 15 to be effective for first half payments, or September 15 for second half payments.
