Snohomish County Property Assessment and Tax Status in August 2026

The current assessed-value appeal deadline is approaching. Snohomish County mailed Official Notices of Value on June 26, 2026. Those values reflect market conditions as of January 1, 2026 and will be used for taxes payable in 2027. The deadline to appeal that 2026 assessed value is August 25, 2026 at 4:00 p.m.
2026 taxes already payable The Treasurer currently provides online access to 2026 and prior-year tax balances and payment history.
First-half deadline April 30, 2026 has passed.
Second-half statutory date October 31 is the Washington second-half property-tax date. Because October 31, 2026 falls on a Saturday, confirm the Treasurer’s posted fall payment instructions or pay before the weekend.
Senior/disabled exemption Maximum disposable household income for 2026 tax relief is $75,000.
Limited-income deferral A separate second-half 2026 homeowner deferral uses a $57,000 maximum 2025 income and must be submitted before September 1, 2026.
Treasurer software transition The Treasurer is transitioning a major software system during summer 2026, and some transactions may take longer than normal.
E-billing is currently unavailable: Snohomish County’s Treasurer states that electronic billing service is unavailable during the current system transition. Do not assume an old e-billing enrollment will replace checking the live tax account.
2026 valuation versus 2026 tax collection

Why a Lower Snohomish Assessment Does Not Automatically Mean Lower Taxes

−1.62% Residential value Countywide total residential assessed value change reported for the 2026 assessment cycle.
+1.49% Commercial value Countywide total commercial assessed value change.
−0.98% Overall value Combined countywide assessed-value change reported in June 2026.
+5.26% 2026 taxes levied Total property taxes collected for all Snohomish County taxing districts increased from 2025.
Countywide tax total: Property taxes for all purposes total approximately $1.948 billion in 2026, up about $97 million from $1.851 billion in 2025.
Market changes also differed by area: Snohomish County reported 2026 assessment-area movement ranging from approximately a 2.28% decrease in the Edmonds area to a 2.38% increase in the Sultan area.
Key rule: Property taxes are budget-driven. Schools, cities, county government, fire districts, hospitals, libraries, sewer districts and voter-approved measures can change levies independently of your individual property’s percentage change.
Use the correct Snohomish County office

Assessor, Treasurer and Auditor Recording Handle Different Property Tasks

County Assessor

  • Assessed market value
  • Parcel characteristics
  • Land and improvement data
  • Comparable property sales
  • Parcel maps and SCOPI
  • Senior/disabled exemptions
  • Open space and forest programs

County Treasurer

  • 2026 property-tax bill
  • Tax balance and receipts
  • Online tax payments
  • Interest and penalties
  • Mailing-address changes
  • Foreclosure payoff
  • Real Estate Excise Tax processing

Auditor Recording

  • Deeds
  • Deeds of trust
  • Mortgages
  • Reconveyances
  • Liens and leases
  • Plats and surveys
  • Certified document copies
Do not ask the Treasurer to lower the assessment: the Treasurer collects the amount calculated from the tax roll. Value and property-characteristic questions start with the Assessor; formal value appeals go to the independent Board of Equalization.

Verify These Property Fields Before Paying or Appealing

Parcel ID Use the complete parcel number for assessment and tax research.
Property address Confirm physical location rather than mailing address.
Owner / taxpayer Compare Assessor data with the latest deed where ownership matters.
Gross acres Compare with deed, plat or survey evidence when acreage affects value.
Market value Verify the assessment year before comparing it with sales.
Tax Code Area Use this to identify the combination of taxing jurisdictions.
Address correction routing: a property-site-address correction belongs with the Assessor. A tax-statement mailing-address change is handled through the Treasurer’s address-change process.

What Snohomish County Assessor Record Fields Mean

Field Meaning What to verify
Parcel ID Unique tax parcel identifier used across county property systems. Match it before paying tax or ordering recorded documents.
Taxpayer / owner Name maintained for assessment and tax administration. Use recorded deeds for legal title verification.
Market value Assessor’s estimate of true and fair market value as of the January 1 assessment date. Compare with relevant arm’s-length sales and correct property characteristics.
Land value Value attributed to the site. Size, location, access, zoning and site limitations.
Improvement value Value attributed to taxable buildings and improvements. Square footage, age, construction, condition and additions.
Gross acreage Approximate acreage shown in Assessor data. Do not substitute this field for a professional boundary survey.
Tax Code Area Number representing the specific combination of taxing districts serving the parcel. Use it when comparing tax rates between nearby properties.
Sales history Recorded transfers processed by Property Control. Determine whether the transaction was a qualified market sale.
Property tax history Historical tax information linked to the account. Use the Treasurer’s current balance for live payoff amounts.
Legal description Abbreviated assessment description of the property. Read the recorded deed or plat for legal transactions.
Snohomish County Online Property Information

How to Use SCOPI to Check Parcels, Tax Areas and Nearby Sales

SCOPI provides a map-based way to locate property and move from a geographic parcel to the detailed Property Account Summary.

Open SCOPI. Start from Snohomish County Online Property Information and launch the interactive map.
Locate the property. Use parcel number or street address, or zoom to the property manually.
Select the parcel polygon. Basic results can show Parcel ID, property address and owner.
Open additional parcel details. SCOPI can show taxpayer, gross acres, market value and Tax Code Area.
Use the Property Account Summary link. This opens deeper detail such as sales history, property-tax history, legal descriptions and structure data.
Turn on useful layers. Appraisal neighborhoods, parcel labels, sales and other available layers can help with comparison research.
Watch for “Multiple Parcels.” SCOPI may use this label where one location contains several taxable units or parcels.
SCOPI parcel lines are not a legal survey: use recorded plats and surveys from Auditor Recording, plus a licensed surveyor when exact boundary location matters.
Annual Washington valuation

How the Snohomish County Assessor Determines Property Value

JAN 1
Assessment date Existing real and personal property is valued as of January 1.
DATA
Property characteristics Land, buildings, location and physical characteristics are reviewed.
SALES
Market evidence The Assessor analyzes qualified sales and appraisal-market areas.
VALUE
True and fair value The annual assessment reflects the Assessor’s market-value conclusion.
2026 notice date: new assessment notices were mailed June 26, 2026 and reflect market value as of January 1, 2026. These are the values used for taxes payable in 2027.
Three recognized appraisal approaches: Washington assessors can use market/sales comparison, cost and income approaches as appropriate for the property type.
Why there is no single Snohomish County tax rate

How Snohomish County Property Taxes Are Calculated

Assessed value The Assessor establishes the property’s taxable market value.
Taxing-district budgets County, city, school, fire, hospital, library, sewer and other local districts certify levies.
Voter-approved measures Bonds, levies and lid lifts can change the amount collected in a Tax Code Area.
Tax Code Area Each TCA represents a particular stack of taxing jurisdictions.
Levy rate The applicable combined rate is multiplied by assessed value to calculate the property’s share.
Treasurer bill The Treasurer receives the completed roll, calculates amounts due and sends tax statements.
Do not copy your neighbor’s tax rate: two nearby properties can be in different city, fire, school or special-district combinations. Compare Tax Code Area first.
2026 context: total taxes levied countywide increased 5.26% even while total assessed value reported for the new 2026 valuation cycle decreased. Budget and levy changes are a major reason assessment percentage and tax percentage do not move together.
Deadline: August 25, 2026 at 4:00 p.m.

How to Appeal the 2026 Snohomish County Assessed Value

Read notice Confirm 2026 value.
Check facts Verify property characteristics.
Gather market proof Sales, repairs and restrictions.
File petition Submit before 4 p.m.
Prepare hearing Follow Board evidence rules.
Official Notice mailed June 26, 2026.
Appeal deadline August 25, 2026 at exactly 4:00 p.m.
Which tax year? The appeal concerns the 2026 assessed value used for taxes payable in 2027.
Electronic filing The petition must be electronically timestamped no later than 4:00 p.m.
Mail filing Mail must carry a timely postmark; the property owner is responsible for verifying the postmark.
Email is not accepted The Board states that emailed petitions will be rejected during the June–August filing window.

Evidence the Board can actually use

  • Official Notice of Value
  • Assessor Property Summary
  • Qualified comparable sales
  • Independent appraisal
  • Repair bids or contractor estimates
  • Photos showing condition
  • Easement documentation
  • Development restrictions
  • Correct measurements or building facts
  • Other market-based evidence
The burden is on the taxpayer: the Board states that the appellant must provide clear, cogent and convincing evidence supporting a different value.
The Board cannot decide based on hardship or percentage increase: another property’s assessment, the amount of tax paid, personal financial hardship or the mere percentage change in value are not substitutes for market-value evidence.
Evidence-file rule: the Board’s current rules limit evidence submissions to a single document no larger than 75 pages. Hearing confirmations and evidence are no longer accepted by email.
Open the Board of Equalization Click the electronic petition option or download the Real Property Petition. Include the Official Notice of Value and file before 4:00 p.m. August 25, 2026.
2026 senior and disability thresholds

Snohomish County Senior Citizen and Disabled Person Property Tax Exemption

2024–2026 income tier Snohomish threshold General tax-relief effect
Threshold 1 $54,000 Excess levies and Part 2 state school levy relief plus the strongest assessed-value reduction tier.
Threshold 2 $64,000 Excess levy/state-school relief plus a smaller assessed-value reduction tier.
Threshold 3 $75,000 Maximum disposable-income threshold for participation in the 2026 exemption program.
Age route Owners generally qualify by meeting the program’s senior-age requirement for the relevant tax year.
Disability route A qualifying disability/retirement status can provide another route into the program.
Principal residence For 2026 relief, the county states participants must reside in the qualifying principal residence in Snohomish County for six months during the calendar year.
2027 change already announced: Washington legislation increases Snohomish County’s maximum exemption-income threshold to $91,000 for tax year 2027, based on 2026 income. Do not apply that $91,000 figure to the 2026 tax year.
New applicant versus renewal: the Treasurer states that a new exemption applicant generally needs to pay the regular tax amount while the application is pending; an approved adjustment can then generate a refund. Renewal applicants can receive a limited grace process after the Assessor approves the renewal.
Open Property Tax Exemptions Select the 2026 application, review the 2024–2026 income thresholds and contact the Exemptions Division at 425-388-3540 when a qualification is unclear.

Limited-Income Homeowner Deferral for the Second Half of 2026 Taxes

2025 income maximum $57,000.
Application deadline Must be submitted before September 1, 2026.
First-half taxes The first half of 2026 property taxes must already be paid.
Primary residence The application applies to the qualifying home the taxpayer occupies.
Ownership Snohomish County’s current checklist requires ownership for more than five years.
State lien Approval creates a lien, and deferred amounts must later be repaid to Washington State after specified triggering events.

Documents the county says to prepare

  • 2025 federal income-tax return
  • Other income documentation
  • Mortgage or lien year-end balance
  • Proof first-half 2026 tax was paid
  • Fire and casualty insurance policy
  • Copy of recorded deed
Deferral is not an exemption: the state pays the deferred amount and secures repayment with a property lien. Sale, transfer, moving from the home, condemnation or death can trigger repayment.
Open Limited-Income Deferral Download the application and publication, verify the $57,000 income ceiling and submit the documentation before September 1, 2026.
2026 and prior taxes online

How to Look Up Snohomish County Property Taxes

Start with the parcel number. Copy the correct parcel ID from the Assessor Property Summary or SCOPI.
Open the Treasurer. Go to the Snohomish County Treasurer.
Select “2026 and prior taxes” or “Pay Taxes Online.” The Treasurer links to the county-authorized payment and account system.
Verify the parcel and taxpayer. Check the property location before using the displayed balance.
Review first-half payment. Mortgage-escrow owners should confirm whether the servicer already paid before submitting another payment.
Review the second-half amount. Confirm the balance due before the October payment period.
Check prior delinquency. Old taxes must generally be handled before assuming only the current installment is due.
Save a receipt or confirmation. Keep the confirmation until the county account shows the payment posted.
Current system transition: some Treasurer requests and transactions may experience temporary delays during the 2026 software implementation.

2026 tax-lien foreclosure status

When Delinquent Snohomish County Property Taxes Become a Foreclosure Risk

Three-year delinquency Washington counties generally foreclose parcels when property taxes become three full years delinquent.
2026 risk year Snohomish County states that a parcel with full-year 2023 or older taxes still unpaid can become eligible for the 2026 tax-lien sale process.
Avoiding filing To avoid the beginning of 2026 tax foreclosure, 2023 and older amounts needed to be paid in full by April 30, 2026.

County Property Search, Homestead & Tax Help Toolkit

Use this free helper to find the right county office, prepare a property search, understand appraised value, review homestead exemption steps, and organize TRIM notice or tax bill questions before using official county websites.

Built for Florida county property guides
Helps users find official resources
No fake database or approval claim
Useful after every article

Find the Correct County Office

Property Appraiser, Tax Collector, Clerk, GIS, and VAB offices do different jobs. Pick your task below.

Quick rule: Property Appraiser = value, records, parcel details, exemptions. Tax Collector = bill and payment. Clerk/Recorder = deeds and recorded documents. VAB = formal value disputes.

Official Property Search Helper

Use this when a county article tells you to search by owner, address, parcel number, folio, PCN, STRAP, or alternate key.

Search tip: If address search fails, try only the house number and main street name. Avoid typing Street, Avenue, Road, Drive, unit numbers, or punctuation unless the official portal requires it.

Homestead Exemption Readiness Check

This helps homeowners prepare before filing through the official county Property Appraiser website.

Important: This is not an eligibility decision. The official county Property Appraiser decides approval, required documents, late filing options, and exemption status.

TRIM Notice & Value Review Helper

Use this to organize your questions before calling the Property Appraiser or preparing an appeal.

Your preparation checklist

Value term Simple meaning
Market value The appraiser’s estimate of the property’s value as of the assessment date.
Assessed value The value after limits or caps may be applied.
Exemptions Approved reductions such as homestead or other exemptions.
Taxable value The value used by taxing authorities after exemptions.

Property Tax Bill Direction Helper

The Property Appraiser values property, but the Tax Collector usually handles the actual bill and payment.

Florida timing reminder: Many Florida tax bills are mailed around November and become delinquent if unpaid after March 31. Always verify exact dates, discounts, and payment fees with the official county Tax Collector.
