Fast Answer

Open the official Assessor Property Search when you have a parcel number or physical street address. Open the Treasurer Tax Search when you need a taxpayer-name search, mailing-address search, tax statement, payment history, receipt or current balance.

Use SCOPI when a parcel is easier to locate visually, including rural land, condominiums, shared-interest property or land with a confusing address. Use Auditor Recording for legal ownership history and recorded documents.

Independent-guide warning: AssessorPropertySearch.org is not Snohomish County. Do not submit bank, card, identification, income or exemption documents through an unverified private website, advertisement, email or text-message link.

How to Search a Snohomish County Property Record

Use the least information needed to locate the parcel, then save the complete parcel number for every later task.

Open the official Assessor Property Search

The current Public Access search accepts a parcel number or property street address. It is not a broad people-search database.

Use the complete parcel number when available

Enter all 14 digits for real property. Personal-property accounts commonly use seven characters and can include letters.

Start an address search with less information

Try the street name, house number plus street name, or a wildcard such as 123*. Avoid city and ZIP code unless needed.

Remove street types and directions

Leave out terms such as N, S, E, W, LN, ST, RD and AVE when the complete address does not match.

Open the matching parcel carefully

Confirm the physical address, property description, category, Tax Code Area and property characteristics before relying on the result.

Save the 14-digit Parcel ID

Use it to move accurately between property values, tax records, SCOPI, sales, appeals and recorded-document searches.

Official wildcard example: entering “Mount” does not automatically return “Mountain.” Entering Mount* can return broader matches.

Fix Address, Owner, Condo and Rural-Parcel Searches

Search problem	Better retry	Why it works
Complete address returns nothing	Use the house number and main street word only.	Directions, suffixes and punctuation can prevent a match.
Only part of the street name is known	Use an asterisk after the known letters.	The wildcard expands the possible street-name matches.
Owner-name search is needed	Use the Treasurer taxpayer-name search.	The main Assessor search is designed around parcel number or property address.
Condo unit does not appear	Search the main address in SCOPI and inspect associated unit parcels.	Condominiums can include unit parcels and separate shared-interest parcels.
Rural mailing address fails	Use the parcel number, SCOPI or township-range-section information.	The mailing address may differ from the parcel’s mapped or situs location.
Recently purchased property shows the prior owner	Confirm the recorded deed, then contact the Assessor.	Recording, assessment and tax-mailing databases can update at different times.
Partial parcel number fails	Enter the entire 14-digit real-property number.	The current portal requires the complete parcel or account number.

Search Snohomish County Tax Bills and Payments

The Treasurer search is the correct portal for bills, balances, receipts, taxpayer names and mailing addresses.

Select the search type

Choose Parcel Number, Taxpayer Name, Property Address or Mailing Address.

Enter one clean search value

Use the complete parcel/account number or at least three street-name characters. Entering less address information usually returns more results.

Open the correct result

Select Account to view the property-tax summary and payment options.

Confirm the tax year and installment

Check whether the displayed amount is current-year first half, second half, full year, prior year or delinquent tax.

Review payment history before paying

A mortgage servicer, title company or prior transaction may already have submitted a payment that has not yet posted.

Official Snohomish County Treasurer Tax Search Search Tax Account

What the Property Account Can Tell You

Record field	How it helps	Important limitation
Parcel number	Exact identifier used across county property systems.	Auditor Recording commonly asks for the first ten digits during parcel searches.
Owner and taxpayer	Shows the names currently associated with the assessment and tax account.	It is not a title report and may lag behind a recent deed.
Property address	Identifies the physical or situs location used by the county.	It can differ from the taxpayer mailing address.
Market and assessed value	Shows land, improvement and total values by assessment or tax year.	The assessed value is not the amount of tax due.
Tax Code Area	Identifies the collection of taxing districts associated with the parcel.	Different parcels on the same street can have different districts or rates.
Property characteristics	May show use code, land, structures, building details and appraisal data.	It is not an inspection, permit approval or survey.
Exemptions	Helps verify tax-relief programs currently displayed.	Pending applications may require direct confirmation.
Tax receipts	Shows payment date, amount and receipt information.	Online and mailed payments can take time to post.

Legal-use warning: assessor ownership, legal descriptions and GIS lines are useful research clues, but they do not replace a deed, title report, recorded survey or professional legal review.

Use SCOPI for Parcel Maps and Visual Research

SCOPI is especially useful when text search is confusing or when several parcels share one address.

Parcel search

Enter the complete 14-digit Parcel ID to zoom directly to and highlight the parcel.

Address search

Begin entering the situs address, then choose the correct suggestion before opening the result.

Neighborhood search

Zoom to an appraisal neighborhood when comparing nearby properties or recent sales.

Parcel-map search

Use quarter, section, township and range information for rural and tax-map research.

Property detail panel

Review owner, taxpayer, acres, market value, Tax Code Area, neighborhood and mapped legal-location information.

Linked reports

Open the Property Account Summary, historical property information, sales search and parcel maps.

Shared-interest parcel: a condominium common area can return a list of related ownership parcels. Select the individual unit parcel before checking value or taxes.

“Not a Legal Tax Parcel”: this label commonly identifies a mapping gap where adjacent legal descriptions do not meet. Do not treat the area as a separate taxable parcel.

Find Comparable Snohomish County Property Sales

Use the official Real Property Sales Search for appeal research, purchase review and neighborhood comparisons.

Search a location or property type

Use the main search field, a wildcard or the available city, ZIP, use-code and neighborhood options.

Open Search Options

Filter by date range, sale-price range and relevant property characteristics.

Keep the result set focused

On-screen results are limited to 200. CSV export can include up to 800 records.

Adjust the sales before comparing

Listed prices are not adjusted. Account for sale date, location, lot, view, waterfront, quality, age, condition and building area.

Appeal evidence tip: select sales close to January 1, 2026 and explain every material difference rather than submitting a long unfiltered sales list.

Understand the Two Different 2026 Property Records

A 2026 tax statement and a 2026 value notice refer to different valuation cycles.

Record	Valuation basis	What it controls
Taxes payable during 2026	Generally the prior assessment cycle, including applicable prior-year new construction.	The tax installments collected by the Treasurer during 2026.
June 26, 2026 Notice of Value	Market value as of January 1, 2026.	Generally the owner’s share of taxes payable during 2027.
Later 2026 new-construction notice	Applicable new construction added as of July 31, 2026.	Can change the value used for taxes collected the following year.

April 30, 2026

First-half or full-year 2026 real-property taxes were due.

June 26, 2026

The Assessor mailed January 1, 2026 value notices for taxes payable in 2027.

August 25, 2026 at 4:00 p.m.

Deadline for appeals tied to the countywide June 26 notice mailing.

October 31, 2026

Second-half taxes are due when the first half was paid on time.

How to Appeal the 2026 Assessed Value

Appeals are filed with the independent Board of Equalization, not with the Treasurer payment portal.

June 26 Official Notices of Value mailed.

August 25 Final filing date for the countywide mailing.

4:00 p.m. Electronic and in-person filing cutoff.

Verify the notice and assessment year

Use the June 26 notice for the January 1, 2026 value and taxes payable in 2027.

Discuss factual issues with an appraiser

Residential Appraisal: 425-388-6555. Commercial Appraisal: 425-388-3390. A discussion does not extend the appeal deadline.

File one petition per parcel

Each 14-digit parcel requires a separate complete and signed appeal petition.

Enter both values

State the Assessor’s land, improvement and total value and your requested land, improvement and total value.

Give specific market-value reasons

Explain incorrect property facts, condition issues, relevant sales or another reason the value does not represent true and fair market value.

File through an accepted method

Submit electronically by 4:00 p.m., mail with a timely postmark, or deliver the petition and Notice of Value in person.

Email is not accepted for the initial petition: petitions emailed during the June–August filing window are rejected. Technical difficulties do not excuse a late petition.

Solicitation-letter warning: the county has warned about private letters containing the wrong deadline or suggesting a reduction continues automatically in later years. Property is reassessed annually.

Other Snohomish County Property-Tax Relief Programs

Senior or disability deferral

A deferral postpones qualifying taxes and generally creates a state lien or repayment obligation. It is different from an exemption.

Limited-income deferral

Qualifying homeowners with limited income may have a separate deferral route with different age, income and repayment rules.

Home-improvement exemption

Qualifying improvements to a single-family dwelling may receive temporary relief. File before construction is complete.

Destroyed property

Property destroyed in whole or part before year-end may qualify for a value adjustment or tax reduction. Report the damage promptly.

Open space and farm land

Current-use programs value qualifying land according to approved use. Removal can trigger additional tax, interest and penalties.

Historic property

Qualifying rehabilitation work can receive special valuation when state and local program requirements are met.

Snohomish County Property Search FAQ

What is the official Snohomish County Assessor property search?

The official Public Access Property Search accepts a complete 14-digit real-property parcel number or a property street address.

Can I search Snohomish County property by owner name?

The main Assessor search uses parcel number or address. Use the Treasurer Tax Search for taxpayer-name searches or Auditor Recording for grantor and grantee names.

How do I fix a failed address search?

Enter less information, remove street directions and suffixes, spell the main street word completely or use an asterisk wildcard. SCOPI can also locate the parcel visually.

Where do I pay Snohomish County property taxes?

Use the Treasurer Tax Search and official payment route. The Assessor determines value, while the Treasurer manages bills, payments, receipts and delinquency.

When are Snohomish County property taxes due?

First-half or full-year taxes are due April 30. Second-half taxes are due October 31 when the first half was paid timely. Annual taxes under $50 are due in full April 30.

For Official Notices of Value mailed June 26, 2026, petitions must be filed by August 25, 2026 at 4:00 p.m.

Finish the Lookup in the Right Order

Search once by address, save the 14-digit Parcel ID and use that identifier across the Assessor, Treasurer, SCOPI, sales, appeal and recording systems.

Protect the August 25, 2026 at 4:00 p.m. appeal deadline, verify payment posting before tax due dates, and use recorded documents or professional survey help for legal ownership and boundary decisions.
