Property Tax Explanation

Click here for a brief explanation of how taxes are calculated and distributed. Including simple examples of each.

Calendar / Due Dates

 Tax statements are mailed no later than March 15th of each year. Current year first half property taxes are due by April 30th. Second half property taxes are due by October 31st. If the tax amount is less than $50, the entire amount is due April 30th. If the due date falls on a Saturday, Sunday or a County observed holiday, then payment will be accepted the next business day.

For billing and other tax questions, contact the Treasurer's Office.

Interest / Penalties / Fees

State law requires the County Treasurer to charge penalty and interest to delinquent property taxes (RCW 84.56.020)

H.B. 1410 adopted by the Washington State Legislature made changes beginning in 2022 to how interest and penalties are calculated on delinquent property taxes:
  • Interest is charged at the rate of 12% per year computed at 1% per month on the full amount of tax owed. 
  • H.B. 1410 suspended the collection of the 3% June 1st and 8% December 1st penalty charges on 2022 property taxes only. 
  • Penalty and interest that has accrued on delinquent property taxes prior to 2022 remains unchanged.
Interest and penalties charged to delinquent property taxes prior to 2022 are calculated as follows:
  • Interest is charged at the rate of 12% per year computed at 1% per month on the full amount of tax owed.
  • Penalty is charged at 3% on the full year amount of tax unpaid on June 1st of the year in which the tax Is due and an additional penalty of 8% on the amount of tax delinquent on December 1st of the year in which the tax is due.
Note: Stormwater, Flood and Irrigation are not assessed penalty. Aquifer is not assessed interest or penalty.

If our office has mailed the tax statement to the address provided by the taxpayer or the taxpayer's agent (such as a closing attorney) under Washington law, we cannot waive the interest and/or penalty if the payment is late.

Tax Statements

Property tax statements are mailed once per year and contain two payment coupons for payments due April 30th and October 31st. If you have not received a statement by March 31st, please contact the Treasurer's Office or call 509-477-4713. It's possible we may have an incorrect mailing address, a mortgage company may be paying your taxes, or we may be holding the statement for an adjustment that needs to be made prior to mailing (i.e. senior or disability exemptions). Failure to receive a Property Tax Statement does not exempt the taxpayer from timely payment of the taxes due. If you have not received a Tax Statement by March 31st, please contact us at 509-477-4713 or fill out a Statement Request form to request a copy of your current statement.

Due to a change in state law, beginning in 2020 all taxpayers receive a full paper statement, including those whose property taxes are paid through escrow. For those who have their taxes paid through escrow, this may be the first time you have received a full tax statement instead of an informational postcard. Under Washington Law, it is the taxpayer's responsibility to insure taxes are paid on their property.

Change the Name or Address

If you wish to change the name or mailing address on your statement, please contact our office. You can also change your name/address online or download the request form. Click here for more information. You may only request a taxpayer change through the Treasurer's Office.

Any request for owner name/address change must be done through the Assessor's Office. A legal document such as a deed, real estate contract, divorce decree, death certificate, or a court document must be provided. Please remember to include your parcel number(s) for any of these requests.

Mortgage Paid Off / New Mortgage Company

When a taxpayer pays off a mortgage during the tax year, they must contact this office to update their billing information and request a duplicate bill. You may only request a taxpayer change through the Treasurer's Office.

Failure to receive a tax bill does not relieve the responsibility for payment, nor constitute cause for cancelation of interest, penalty and/or cost charges if the tax bill becomes delinquent.

Misplaced Statement

If you have misplaced your statement, a new one can be faxed, e-mailed or mailed to you. You can also request a statement online or download the request form. For more information, go to the Forms section.
