Your Property Tax Bill Is Due April 30. Here Is What It Actually Says.

• April 30 is the first-half deadline.
• October 31 is the second-half deadline.
• If your annual tax is under $50, the full amount is due April 30.

If taxes become delinquent, interest and applicable penalties are controlled by Washington law. The Snohomish County Treasurer publishes the current payment information and options.

What the typical bill did

From Snohomish County's 2026 property-tax information, the typical residence countywide changed like this:

• Assessed value went from $695,200 to $741,800, up 6.7%.
• The tax bill went from $5,754.59 to $6,078.98, up $324.39, or 5.6%.

Closer to home, Arlington's typical residence went from $510,400 to $523,200 and the tax bill went from $4,427.67 to $4,559.79.

That is about $132 more, roughly a 3.0 percent increase.

Here is the part that surprises people

The average levy rate went down.

The typical countywide rate fell from $8.2776 per $1,000 of assessed value to $8.1949.

At the same time, all taxing districts in Snohomish County together are collecting about $1.949 billion for 2026, up roughly $97.4 million from $1.852 billion in 2025.

That is a 5.26 percent increase in total property taxes collected while the typical levy rate went down.

Both can be true because Washington's property-tax system is largely levy and budget driven.

Taxing districts establish the amount they are legally authorized to levy, subject to constitutional, statutory and voter-approved limits. Assessed values then help determine how that levy is distributed among taxable properties.

That means market appreciation alone does not simply get multiplied by the old tax rate to create a windfall of the same percentage.

For an individual owner, though, assessed value does matter because your property's value relative to other taxable property in the same districts affects your share of those levies.

That distinction is the key.

Every property tax dollar in Snohomish County, 2026

The County Assessor's 2026 distribution looks like this:

• Local school districts: 35.39%
• State school levy: 27.28%
• Fire districts: 14.42%
• Cities and towns: 7.63%
• County: 5.90%
• Roads: 3.95%
• Libraries: 3.20%
• Regional Transit Authority: 1.18%
• Hospitals: 0.67%
• Ports: 0.32%
• Parks and recreation: 0.06%

Almost two-thirds goes to local and state school levies.

Fire districts are the next-largest category.

The county general levy is 5.90 percent of the total. County road levies account for another 3.95 percent and apply to properties in the county road district.

So when somebody says "the county raised my taxes," it helps to look at the actual districts printed on the statement before deciding which government or levy changed.

What moved this year

Increase by type of taxing district, 2025 to 2026

Fire districts accounted for about $41.9 million of the $97.4 million countywide increase.

Local school districts accounted for another $34.1 million.

Fire-district taxes rose 17.5 percent as a category, and local school-district levies rose about 5.2 percent.

The county also identified voter-approved measures contributing to 2026 taxes, including fire, EMS and school measures.

But it would be too simple to say the entire countywide increase was "voted in."

Other categories increased too, including the state school levy, county levy, cities, roads, libraries and other districts.

The accurate version is that voter-approved measures were an important part of the 2026 change, particularly in some districts, while the total increase came from several levy categories.

I spent close to eight years with Arlington Fire, so I have some idea what a fire levy pays for.

The point here is not whether any particular levy was good or bad.

It is knowing which line actually changed.

Every city can see property values move in one direction while tax bills move differently.

That is exactly what happened in 2026.

Change in the typical tax bill, 2025 to 2026

Marysville's typical assessed value increased 2.8 percent while its typical tax bill fell $87.68.

Granite Falls' typical value increased 4.7 percent while its typical bill fell $512.90.

Edmonds' typical value increased 6.5 percent while its typical bill rose $1,220.45.

Same county. Same tax year. Very different results.

That is because each property sits inside its own combination of taxing districts and because an owner's share depends not simply on whether their value rose, but how it changed relative to other property within those districts.

The value on this bill is fifteen months old

The assessed value used for your 2026 taxes is the January 1, 2025 assessed value.

New construction is handled on a separate July 31 assessment date.

So when this article was first published on April 21, 2026, the value behind the bill reflected an assessment date more than fifteen months earlier.

Two things follow.

Do not price your house off it

I get asked this all the time.

"The county says my place is worth this. Should we list there?"

No.

Not because the Assessor is bad at the job.

An assessed value and a listing price are two different tools built for two different jobs.

The Assessor values a huge number of properties for taxation as of a fixed date.

A current listing price should be built from recent comparable sales, current competition, condition, location and what buyers are doing now.

If you are selling, use current market evidence.

I will pull it for your address and you do not have to list with me to see it.

You cannot appeal the tax bill itself

The Board of Equalization hears appeals of assessed value, not complaints about the amount of tax somebody can afford or whether a levy is too high.

The 2026 Official Notices of Assessed Value for taxes payable in 2027 were mailed June 26, 2026.

The regular appeal deadline has now passed.

The Board says limited circumstances may allow a late filing, so contact the Clerk if you believe you qualify.

Check whether you qualify for relief

For the 2026 tax year, the Snohomish County income threshold for the Senior Citizens and People with Disabilities Property Tax Exemption is $75,000.

Broadly, an applicant must meet the age or disability requirements, own the residence and occupy it as the principal residence for the required period.

The exemption is different from a deferral. An exemption reduces qualifying taxes and does not create the repayment obligation that comes with a tax deferral.

And there is an important change coming:

For the 2027 tax year, Snohomish County says the income threshold rises to $91,000, based on 2026 income.

If somebody previously assumed they made too much to qualify, that new threshold is worth another look.

The Assessor also administers other relief programs, including deferrals and certain land-classification programs.

Know the next appeal window

The June 26, 2026 assessed-value notices set values used for taxes payable in 2027.

The normal deadline was 60 days from the mailing date or July 1, whichever was later.

That regular deadline has passed.

For future notices, do not put the envelope in a drawer.

An assessment appeal is about market value as of the assessment date.

The Assessor's value is presumed correct under Washington law, so the property owner has to provide evidence supporting a different value.

Useful evidence can include:

• Errors in the property record
• A recent arm's-length sale of the property
• Comparable sales near the assessment date
• Written estimates for significant condition issues
• Documents showing development restrictions or easements that affect value

Things the Board says it cannot use as the basis for changing market value include:

• Other properties' assessed values
• The percentage increase in your assessment
• Personal financial hardship
• Complaints about the amount of tax itself

For an existing appeal, evidence must be provided to both the Board and Assessor no later than 21 business days before the hearing. The Board now requires electronic evidence to be submitted through its web process rather than ordinary email, and current filing rules should be checked before submitting anything.

Plenty of homeowners never write a property-tax check because the lender collects money in escrow with the monthly mortgage payment and pays the taxes when due.

That does not mean the tax increase disappears.

A $324 annual increase works out to about $27 per month before any escrow shortage or cushion adjustment.

If your mortgage payment changed, property taxes are one of the first things worth checking.

The bottom line

For 2026, Snohomish County property owners are paying roughly $1.949 billion across all taxing districts.

The typical countywide residence saw a higher bill even though the average levy rate went down.

That makes a lot more sense once you separate three things:

Your assessed value.

Your taxing districts.

And the levies those districts are authorized to collect.

If you are selling, do not use the tax assessment as your asking price.

If you are looking for tax relief, check the exemption rules.

And when the next assessed-value notice arrives, open it while the appeal clock is still running.
