Why can two similar houses in Bothell, Washington have significantly different property tax bills, and what should you check before choosing which home to buy?
Bothell sits in two counties: King County and Snohomish County. Your property tax bill depends not simply on the word “Bothell” in your address, but on the property’s assessed taxable value and the specific combination of state, county, city, school, EMS, and other taxing districts that apply to that parcel.
That means two homes that look nearly identical, and may even be located surprisingly close to one another, can carry meaningfully different annual tax bills.
And when you’re buying a Bothell home approaching $1 million, even a relatively small difference in the effective tax rate can translate into $1,000 or more per year.
PART 1: THE BOTHELL TAX LINE MOST BUYERS DON’T THINK ABOUT
Imagine you’re comparing two Bothell homes.
Both are around $900,000.
Both have similar square footage.
Both have three or four bedrooms, similar updates, similar lots, and comparable commute times.
One appears to be the better financial choice because the purchase prices are nearly identical.
Then you look at the property tax history.
One tax bill is noticeably higher.
That’s when many buyers ask me:
“Why am I paying more in taxes if the houses cost almost the same?”
The answer starts with something unusual about Bothell.
Bothell Is One City, but It Crosses a County Line
Bothell is divided between King County and Snohomish County. The City of Bothell’s property tax information confirms that Bothell property owners pay property taxes to either King County or Snohomish County depending on where the property is physically located.
That’s more important to a homebuyer than it might initially sound.
Although the City of Bothell portion of the property tax is the same across the city, the total property tax rate is made up of multiple taxing entities. According to the city, those can include the county, state, school districts and other local levies. EMS levies can also differ between counties.
So you’re not dealing with one universal “Bothell property tax rate.”
You’re dealing with a stack of taxes tied to the exact property.
That’s the invisible line buyers need to understand.
The “$1,000 Difference” Is Not Just a Hypothetical
Current property-level market data helps illustrate why this matters.
As of April 2026, Ownwell reports a 0.95% median effective property tax rate for Bothell properties in King County and a median annual tax bill of $8,472. For Bothell properties in Snohomish County, it reports a 0.82% median effective rate and a median annual tax bill of $7,172.
Those are medians, not guaranteed rates for a particular house, but the difference between those reported median bills is about $1,300 per year.
That’s approximately:
- $108 per month
- $6,500 over five years, assuming the difference stayed unchanged
- $13,000 over ten years, again assuming the difference stayed unchanged
That doesn’t mean every Snohomish County Bothell home has lower taxes than every King County Bothell home.
It absolutely does not.
The exact parcel and taxing districts matter.
But it demonstrates why property taxes deserve attention before you compare two homes solely on purchase price.
For current third-party market data, compare Ownwell’s Bothell–King County property tax data with its Bothell–Snohomish County property tax data.
Why ZIP Codes Don’t Tell the Whole Story
You’ll often hear the Bothell tax discussion simplified this way:
98011 = King County
98012 and 98021 = Snohomish County
That shorthand can help you understand the geography, but I would not use a ZIP code as your final tax calculation when buying a house.
ZIP codes exist primarily for mail delivery. Taxing districts are based on jurisdictional boundaries.
The safer question isn’t:
“What’s the tax rate in this ZIP code?”
It’s:
“What taxing districts apply to this exact parcel, what is its current assessed taxable value, and what does its actual tax record show?”
That’s the information you want before you build a housing budget.
How Washington Property Taxes Actually Work
This is where the subject gets more interesting.
Washington uses what the state describes as a budget-based property tax system.
According to the Washington State Department of Revenue, taxing districts determine how much property-tax revenue they need, subject to legal limits. The county assessor then calculates a levy rate based on the levy amount and the total taxable value within that district. Rates are generally expressed as dollars per $1,000 of assessed value.
At the individual-property level, the concept can be simplified to:
Taxable assessed value × applicable combined levy rates = property tax
But the key word is combined.
Your bill can include taxes levied by several different government and taxing entities.
The Washington Department of Revenue explains that property tax bills can contain levies from the state, county, city, schools and other “junior” taxing districts.
That’s why crossing a jurisdictional boundary matters.
The house hasn’t necessarily changed.
The taxing structure around it has.
What About the Assessed Value?
There’s another misconception I hear from buyers:
“If I’m paying $950,000 for the house, won’t my property tax automatically be calculated on $950,000?”
Not exactly.
Washington law requires county assessors to appraise property at 100% of true and fair market value, according to the state’s Department of Revenue. County assessors use accepted appraisal approaches to determine that value.
But your purchase price and the county’s current assessed taxable value are not simply interchangeable numbers.
That’s why, when you’re evaluating a Bothell property, you want to review the assessor’s record rather than multiplying the listing price by a generic tax percentage you found online.
You can learn more about the state’s assessment process through the Washington Department of Revenue’s residential property valuation guide.
The 1% Rule Buyers Frequently Misunderstand
Washington has a property-tax levy growth limitation that is often shortened to “the 1% rule.”
That shorthand can create a dangerous assumption:
“My property tax can’t increase by more than 1% per year.”
That’s not what the rule means.
The Washington Department of Revenue specifically explains that the 1% limitation applies to increases in certain taxing districts’ levy revenue, not to the tax bill of each individual home. Individual property taxes can rise by more or less depending on factors including changes in assessed value relative to other properties and voter-approved tax measures.
For taxes due in 2026, the state’s published limit factor for applicable districts with populations of 10,000 or more is 101%, assuming the required authorization is adopted.
So don’t build a long-term Bothell housing budget under the assumption that:
“Whatever the seller pays today can only go up 1% next year.”
That’s an oversimplification.
Read the state’s full explanation here: How Washington’s 1% property-tax levy limit works.
Bothell Has Its Own Levies Too
The county line isn’t the only thing affecting the bill.
The City of Bothell lists several city levies, including its regular levy as well as voter-approved measures supporting public safety, streets and sidewalks, and a fire-station general-obligation bond.
King County’s 2026 property-tax information also notes Bothell’s 10-year renewal of the Safe Streets and Sidewalks lid lift among measures affecting the 2026 tax year.
Meanwhile, Snohomish County’s 2026 annual assessor report lists a typical Bothell levy rate of $8.0664 per $1,000 of assessed taxable value for its side of the city, while explicitly warning that rates may vary within cities.
That final warning matters.
There is no substitute for checking the individual property.
A Better Way to Compare Two Bothell Homes
Suppose you’re deciding between House A and House B.
House A costs $925,000.
House B costs $915,000.
At first glance, House B appears $10,000 cheaper.
But purchase price is only one part of the cost of ownership.
Before deciding which home is financially stronger for you, I would compare:
- Current property tax bill
- Current assessed taxable value
- County
- Applicable taxing districts
- Recent assessment history
- HOA dues, if applicable
- Insurance estimates
- Expected maintenance
- Financing and interest costs
- Your intended ownership timeline
This is especially important when you’re comparing homes on opposite sides of Bothell’s jurisdictional boundaries.
A house that is $10,000 less expensive isn’t automatically the lower-cost house to own.
And a house with the lower property tax bill isn’t automatically the better purchase either.
The goal is to understand the complete financial picture.
Why This Matters Even More for Bothell’s Higher-Priced Homes
Property-tax differences become more visible as assessed values rise.
To illustrate, not to predict a particular property’s bill, consider two hypothetical homes with the same $1 million taxable assessed value.
If one had a combined effective tax burden equivalent to 0.95%, that would equal roughly $9,500 annually.
At 0.82%, the corresponding figure would be about $8,200.
That’s a theoretical difference of $1,300 per year.
Those percentages mirror the 2026 median effective rates reported by Ownwell for Bothell’s King and Snohomish County datasets, but they are not parcel-specific levy rates and should not be used as a quote for a particular home.
This is precisely why luxury and move-up buyers should pay attention.
At higher home values, small percentage differences can turn into meaningful annual dollars.
What I Want Bothell Buyers to Take From This
The lesson isn’t:
“Always buy on one side of Bothell.”
That’s far too simplistic.
The lesson is:
Know which side you’re buying on, understand the property’s actual tax history, and compare total ownership costs before you make a decision.
A lower-tax property might not have the location, lot, layout, condition, appreciation potential, commute, or other characteristics you value.
Real estate decisions shouldn’t be made from one number.
But they also shouldn’t be made while ignoring a recurring expense that can add up to thousands of dollars over the years.
Continue to Part 2: What Bothell buyers should check before making an offer, how to verify a property’s actual tax information, FAQs, and why hyperlocal representation matters when buying across the King–Snohomish line.
WHAT TO CHECK BEFORE YOU BUY
Knowing Bothell crosses the King–Snohomish county line is useful.
Knowing what to do with that information before making an offer is where it becomes valuable.
If you’re comparing Bothell homes, here is the process I recommend.
Step 1: Identify the County for the Exact Property
Don’t rely solely on the mailing address or ZIP code.
Verify whether the parcel is actually located in King County or Snohomish County.
The City of Bothell itself directs property owners to the appropriate county for detailed tax information.
For a King County property, start with the King County Assessor’s property-tax resources.
For Washington property-tax rules generally, the Washington State Department of Revenue property-tax portal explains how assessments and local administration work.
The county matters because your county assessor determines the property’s assessed value and calculates applicable levy rates, while the county treasurer collects the taxes.
Step 2: Look at the Actual Tax Bill, not Just an Online Estimate
Online calculators are useful for orientation.
They are not a substitute for parcel-specific records.
If a listing website says “estimated taxes: $7,900,” I don’t want you treating that figure as guaranteed.
Look at the official record.
Then ask:
What was actually billed?
What is the current assessed taxable value?
Has that assessment changed significantly?
Which taxing districts are represented on the bill?
Are there exemptions or circumstances associated with the current owner that may not apply to me?
That final question can be especially important.
The tax history belongs to the property under its existing circumstances. Your future housing budget deserves a fresh analysis.
Step 3: Compare Like With Like
This is one of the biggest mistakes buyers make when comparing property taxes.
Suppose House A has a tax bill of $8,500 and House B has a tax bill of $7,200.
You cannot automatically conclude:
“House B’s tax rate is lower.”
First compare their assessed values.
A higher tax bill can result from a higher assessed value, a different combination of levy rates, or both.
Washington’s Department of Revenue explains that taxable property is generally valued at 100% of true and fair market value unless an exemption applies, while individual tax bills reflect the levies applicable to the property.
So the right comparison isn’t just:
Tax Bill A vs. Tax Bill B.
It’s:
Assessed value + applicable levies + actual bill + property characteristics.
That’s a much more useful comparison.
Step 4: Turn the Annual Number Into a Monthly Number
Buyers naturally focus on the purchase price because it’s the largest number on the screen.
But your day-to-day budget is monthly.
Suppose one property costs $1,200 more per year in taxes.
That’s approximately:
$100 per month.
If the difference is $1,500:
$125 per month.
Now the decision becomes easier to understand.
Would you willingly pay an additional $100–$125 each month for the advantages offered by that particular home?
Maybe yes.
Maybe no.
The important part is that you’re making that choice knowingly.
Step 5: Consider the Cost Over Your Expected Ownership Period
Now zoom out.
A $1,200 annual difference equals $6,000 over five years if it remained constant.
A $1,500 annual difference equals $7,500 over five years if it remained constant.
Those simple calculations aren’t forecasts, property values, levies and tax bills can change, but they demonstrate why seemingly modest annual differences deserve attention.
The same logic applies to HOA dues, insurance, maintenance and financing.
A strong purchase decision considers total cost of ownership, not merely the price printed on the listing.
“But Marie-Noelle, Which Side of Bothell Should I Buy On?”
This is where I deliberately avoid giving buyers a blanket answer.
Neither county is automatically “better.”
And choosing a home based solely on which county has the lower current median effective tax rate would ignore almost everything else that makes a property valuable to you.
Your decision may involve:
- The specific home and lot
- Price and negotiating position
- Property condition
- Commute and transportation needs
- Access to the amenities important to you
- Resale considerations
- HOA costs
- Insurance
- Property taxes
- Your expected time in the home
The purpose of understanding the King–Snohomish distinction is not to steer you toward one side.
It’s to make sure you don’t discover an important ownership cost after you’ve already fallen in love with a house.
Why Hyperlocal Bothell Knowledge Matters
A national home-search website can tell you the asking price.
A mortgage calculator can estimate principal and interest.
A map can show you the commute.
But buying intelligently in a city like Bothell requires another layer of analysis.
Bothell isn’t financially uniform.
It crosses county boundaries. Taxing districts overlap in different ways. Assessments change. Voter-approved levies change. The financial picture attached to one property may not match another home only a short distance away.
The City of Bothell explicitly notes that while the city’s own portion is the same across the two counties, the overall property-tax rate differs because the total bill incorporates numerous taxing entities.
That’s the kind of detail I want my buyers thinking about before the offer.
Marie-Noelle Metseye: Helping Bothell Buyers Look Beyond the Listing Price
My role as your real estate advisor isn’t simply to open a door and tell you whether the kitchen is beautiful.
You can see the kitchen.
The greater value comes from helping you ask questions that aren’t always obvious from the listing photos.
What does this property actually cost to own?
How does it compare with the alternative three streets away?
What does the tax record tell us?
Which county are we in?
Are we comparing two properties on an equal financial basis?
What recurring costs should be included in your decision?
That’s especially important for luxury and move-up buyers.
When you’re making a substantial real estate investment, small differences in annual carrying costs can compound over time. A sophisticated purchase strategy therefore looks beyond asking price and considers the complete ownership picture.
As a Luxury Realtor serving Bothell and the surrounding market, I help buyers evaluate homes in context, not as isolated listings.
That means looking at the details that can influence both your experience of owning the property and the financial decision behind it.
Bothell’s King–Snohomish divide is a perfect example.
Two listings can both say “Bothell.”
Two homes can both be around $900,000 or $1 million.
They can appear remarkably similar online.
But the underlying ownership costs don’t necessarily match.
My goal is to help you uncover those differences early enough that they become part of your strategy, not a surprise after closing.
A Bothell Buyer’s Pre-Offer Tax Checklist
Before you write an offer on a Bothell property, ask these questions:
- Is this property in King County or Snohomish County?
- What is its current assessed taxable value?
- What was the most recent annual property tax bill?
- Which taxing districts apply to this parcel?
- How has the assessed value changed recently?
- How does the tax bill compare with the other homes I’m seriously considering?
- Does the current owner’s situation include an exemption that affects what I’m seeing?
- What would the tax amount mean for my estimated monthly housing budget?
- Am I comparing total ownership costs, or only asking prices?
Those nine questions can give you a much clearer financial picture than simply searching “Bothell property tax rate” and applying the first percentage you find.
Frequently Asked Questions About Bothell Property Taxes
Is Bothell in King County or Snohomish County?
Both.
Bothell spans King and Snohomish counties. The City of Bothell confirms that property owners pay property taxes to the county in which their property is located.
That unusual geography is one reason buyers should verify the county for each property rather than assuming every Bothell address follows the same tax structure.
Are Bothell property taxes higher in King County or Snohomish County?
There isn’t one universal answer for every property.
However, current 2026 third-party data from Ownwell reports a median effective property tax rate of 0.95% for Bothell in King County versus 0.82% for Bothell in Snohomish County. It reports median annual tax bills of $8,472 and $7,172 respectively.
Those figures are useful for understanding the broader pattern, but the actual tax bill for a home depends on its assessed taxable value and applicable taxing districts.
Always verify the individual parcel before making a financial decision.
Can two $1 million Bothell houses really have tax bills that differ by more than $1,000?
Yes, it’s possible.
Using the 0.95% and 0.82% median effective rates reported in the 2026 Ownwell Bothell datasets purely as an illustration, a $1 million value would produce a mathematical difference of approximately $1,300 annually.
But that’s an illustration, not a promise that any two $1 million homes will have exactly that difference.
Is 98011 always King County and 98012 or 98021 always Snohomish County?
Those ZIP codes are commonly associated with those sides of the Bothell area, but don’t use a ZIP code as your definitive property-tax jurisdiction check.
For a purchase decision, verify the actual parcel and county record.
Does Washington limit my property-tax increase to 1% per year?
No.
This is a common misunderstanding.
Washington’s 1% levy limitation applies to certain increases in taxing-district levy revenue. It does not guarantee that an individual homeowner’s tax bill can increase by only 1%.
Your individual bill can change differently depending on assessed-value movements, taxing districts and voter-approved measures.
Who determines my home’s assessed value?
The county assessor.
Washington’s Department of Revenue says property taxes are administered locally: county assessors determine property values, while county treasurers collect the taxes and distribute the revenue to local governments.
Can I appeal a property assessment?
Washington provides a process for challenging an assessed valuation through the applicable county board of equalization.
The Department of Revenue advises property owners to contact their county assessor or board of equalization for the applicable forms and filing deadline.
You can review the state’s guidance at Washington Department of Revenue: Paying or Appealing Property Tax.
Final Takeaway: Don’t Shop for a Bothell Address, Shop for the Actual Property
The invisible line running through Bothell isn’t something most buyers notice when scrolling through listings.
But financially, it can matter.
Bothell stretches across two counties, and the property-tax bill attached to a home reflects much more than its city name.
County.
Assessed taxable value.
School levies.
City levies.
State taxes.
Other taxing districts.
Voter-approved measures.
All of those pieces can affect what you ultimately pay.
That’s why two houses that seem nearly identical can carry noticeably different tax bills.
The smartest response isn’t to automatically choose the lower-tax property.
It’s to know the difference before you choose.
When I help buyers compare Bothell homes, that’s the level of detail I want included in the conversation.
Because the best home isn’t simply the one with the right list price.
It’s the one whose location, property, lifestyle fit and total cost of ownership make sense for you.
If you’re thinking about buying in Bothell, don’t wait until you’re under contract to figure out which side of the county line you’re on.
