Past due Clark County property taxes to incur interest on July 1, 2020

Published Date

Vancouver, Wash. – Clark County Treasurer Alishia Topper reminds taxpayers that 2020 first-half property taxes were due June 3 and accounts with the first-half payment outstanding will incur 1% interest beginning Wednesday, July 1.

The deadline was extended for individual residential and commercial taxpayers due to the COVID-19 state of emergency. The due date extension to June 3 eliminated the standard interest accrual occurring in May and June and a 3% penalty usually assessed on June 1.  

Taxpayers still past due on their 2020 first half taxes will incur 1% interest on July 1 and will continue to be assessed monthly interest until the first-half’s taxes are paid. Interest is assessed on the entire year’s bill amount, not only the past due balance.

Payments can be made:

  • Online at (transaction fees for online payments may apply)
  • By mail using a check or money order addressed to Clark County Treasurer, PO Box 35150, Seattle, WA 98124-5150 (cash should not be sent through the mail)
  • Via check or money order using the specially marked secure dropbox at the Clark County Public Service Center, 1300 Franklin St. (cash payments may not be deposited in the dropbox).  As of June 26, masks are required for all individuals entering the Public Service Center.

Past due notification postcards were mailed to individuals with past due amounts. Taxpayers who need to obtain their amount due can visit the online Clark County Property Information Center and search for their account using their Property Account Number or address:

Taxpayers can also contact the Clark County Treasurer’s Office at or by leaving a voicemail at 564.397.2252. Treasurer’s Office staff will respond on the same day if the voicemail is left before 4 pm, Monday – Friday.
