Snohomish County Tax Collector: Pay Your Tax Bill & Check Office Hours

Use this page to find the correct payment route, due dates, Treasurer office hours, mailing instructions, electronic-payment fees and the right office when your question is really about assessed value or an exemption.

Online property tax payment fees
Snohomish County states that electronic-payment processing costs are paid by the payer and go to the third-party processor rather than the county. Review the final charge before authorizing a transaction because processor terms can change.
| Payment method | Listed fee | Important detail |
|---|---|---|
| Credit card | 2.35% | $2.50 minimum charge; county lists Mastercard, Visa, American Express and Discover. |
| Debit card | $3.50 | Processor convenience fee applies. |
| eCheck | $1.50 | Bank account and routing numbers are required. |
| Returned bank item | $35 | The county states this processing fee applies to returned bank items. |
Paying Snohomish County property tax by mail
Make a mailed check or money order payable to Snohomish County Treasurer and include the property account number. The official mailing address is:
M/S 501
Everett, WA 98201
Mailed payments must be postmarked by the applicable tax due date. The Treasurer advises allowing additional mailing time and notes that checks can also be placed in the county tax-payment drop box.
What happens when Snohomish County property taxes are late?
Late property taxes can become subject to interest and penalties under Washington law. Snohomish County states that delinquent charges are assessed according to the property type and that delinquent fees are assessed on the first day of each month.
If the first-half payment is not made by April 30, the county states that the full year’s tax becomes delinquent and interest or penalties may be assessed on the full amount due.
For delinquent-property-tax payment-plan questions, the county directs taxpayers to the Treasurer’s foreclosure staff at 425-388-3606. Do not assume a current-year payment arrangement also resolves older delinquent taxes.
Tax foreclosure payments have different rules
A property already in Snohomish County tax foreclosure does not follow the ordinary online-payment process. The Treasurer requires the full qualifying amount, including applicable taxes, interest, penalties and foreclosure-related costs.
Foreclosure cases are time-sensitive and can have year-specific deadlines. Use the county’s current foreclosure instructions rather than relying on an older notice or a general tax-payment page.
Treasurer or Assessor: who handles your question?
- Taxes currently owed
- Tax payments already made
- Payment receipts or statements
- Payment methods and processing
- Delinquent-tax questions
- Tax foreclosure matters
- Assessed property value
- Value notices
- Many property-tax exemption programs
- Senior and disability exemptions
- Property characteristics and assessment records
A tax statement and an assessed-value notice are not the same document. The Treasurer issues the tax statement showing taxes owed, while the Assessor determines the assessed value used in calculating property taxes.
Property tax exemptions and deferral programs
Snohomish County’s Assessor administers several property-tax relief programs, including programs for qualifying senior citizens and people with disabilities, limited-income homeowners, historic property and certain other qualifying property owners.
Eligibility, income thresholds, application years and supporting-document requirements vary by program. A tax exemption can reduce qualifying taxes but does not necessarily remove every tax charge or automatically stop a foreclosure case.
