The bill comes from the Clark County Treasurer's Office. The value it is based on is set by a separate office, the Clark County Assessor's Office, which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
Washington collects in the same calendar year it names: the 2026 bill is paid April 30 and October 31, 2026, and is based on the value the assessor set as of January 1, 2025. Notices of value mailed in 2026 (mostly in June, the rest in September) set the value used for 2027 taxes, so an appeal filed now affects next year's bill. Online payment goes through the county's processor, Point & Pay: e-checks are free, debit cards $3.95 flat and credit cards 2.39%. Every relief program the treasurer lists is a state program: the senior and disabled exemption, the senior and disabled deferral, partial payments, and a one-time interest and penalty waiver for income-qualified homeowners facing foreclosure.
When are property taxes due in Clark County?
For the 2026 bill, Clark County splits the bill into 2 payments, the first due April 30, 2026 and the last October 31, 2026. The next one due is the second half, on October 31, 2026. Unpaid amounts are charged monthly interest from the date of delinquency until paid: 0.75% a month on residential parcels with four or fewer units (no penalties), and 1% a month on all other parcels plus penalties of 3% on June 1 and 8% on December 1. These rates apply to 2023 and later tax years.
| Payment | Due | Note |
|---|---|---|
| First half (or full amount) | April 30, 2026 (passed) | Already past for the 2026 cycle. The treasurer's payment-dates page gives the recurring schedule; RCW 84.56.020 fixes it statewide. |
| Second half | October 31, 2026 | The county prints 'Second half 2026 property tax due date is Oct. 31.' Oct. 31, 2026 is a Saturday. The county page gives no weekend rule, but state law does: under RCW 1.12.070, when a date for a tax remittance falls on a Saturday, Sunday or legal holiday, payment is timely if made on the next business day, and the Department of Revenue's 2026 Property Tax Calendar marks Oct. 31 with that rule. So a payment made Monday, Nov. 2, 2026 is on time. The treasurer also accepts online payments made by 11:59 pm on the due date and mail postmarked by the due date as timely. |
From Clark County's published schedule, checked September 23, 2026. If a date falls on a weekend or holiday, the county's own rules on the next business day apply.
