Travis BunnTravis Bunn·Updated July 22, 2026

Skagit County is located in northwestern Washington with Mount Vernon as its county seat and largest city. The county has a population of approximately 130,000 and includes major cities such as Mount Vernon, Anacortes, Burlington, and Sedro-Woolley. Property tax appeals matter in Skagit County because the median annual property tax bill of $4,008 is significantly higher than the national median of $2,400, creating substantial opportunities for savings when assessments are inaccurate. The county's effective tax rate of 0.82% is slightly above the Washington state median of 0.79%, making Skagit one of the higher-taxed counties in the state.

How Skagit County Assesses Property

100%of market value

Assessed by: Skagit County Assessor's Office

Assessment cycle: annual

Notices typically mailed: May through December

Washington State assesses all residential property at 100% of true and fair market value as of January 1st each year. In Skagit County, this means your assessed value equals your home's full market value with no reduction. For example, if your home's market value is $486,200 (the county median), at Washington's 100% assessment ratio your assessed value would be $486,200, resulting in approximately $4,008 in annual taxes at the county's effective rate of 0.82%.

The Appeal Process

Appeals are heard by the County Board of Equalization. Hearings before the Skagit County Board of Equalization are informal and typically last 30 minutes for residential properties. You'll present your evidence, the Assessor's representative will present their case, and Board members may ask questions. You can represent yourself without an attorney.

1

Step 1: Review your Notice of Value from the Skagit County Assessor's Office carefully and compare your assessed value to recent sales of similar properties in your neighborhood.

2

Step 2: Gather supporting evidence including comparable sales data (3-5 similar properties that sold for less than your assessed value), photographs documenting property condition issues, repair estimates for any defects, and any assessment errors such as incorrect square footage or features.

3

Step 3: File a Petition for Appeal form with the Skagit County Board of Equalization by July 1 or within 30 days of your Notice of Value mailing date, whichever is later. Include your parcel number and a brief explanation of why you believe the assessment is too high.

4

Step 4: After filing, the Assessor's Office may contact you for an informal review to discuss your concerns. Many appeals are resolved at this stage without a formal hearing.

5

Step 5: If the informal review doesn't resolve your appeal, attend your formal hearing before the County Board of Equalization. Present your evidence clearly, focusing on comparable sales and objective data showing your assessed value exceeds market value.

6

Step 6: Receive the Board's written decision, typically within 45 days of your hearing. If you disagree with the decision, you can appeal to the Washington State Board of Tax Appeals within 30 days of the decision mailing date.

7

Step 7: As a final option, if the State Board of Tax Appeals decision is unfavorable, you may appeal to Skagit County Superior Court for judicial review.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Skagit County?
The deadline to file a property tax appeal in Skagit County is July 1, 2026, or within 30 days of the date on your Notice of Value mailed by the Assessor's Office, whichever date is later. Since assessment notices are mailed throughout the year (typically May through December), your specific deadline depends on when your notice was mailed. Missing this deadline means you must wait until the next assessment year to file an appeal, so mark your calendar immediately when you receive your notice.
How do I file a property tax appeal in Skagit County?
To file a property tax appeal in Skagit County, you must complete a Petition for Appeal form and submit it to the Skagit County Board of Equalization at 700 South 2nd Street, Mount Vernon, WA 98273. You can file in person during business hours (Monday-Friday, 8:00 AM - 4:00 PM) or by mail. The petition must include your parcel number, property address, the assessed value you're appealing, and a brief explanation of why you believe the assessment is incorrect. Along with the form, gather supporting evidence such as comparable sales data, photographs of property defects, or documentation of assessment errors.
What evidence do I need for a successful Skagit County property tax appeal?
The most compelling evidence for a Skagit County property tax appeal includes comparable sales data showing 3-5 similar properties that sold for less than your assessed value, ideally sold close to the January 1 assessment date. Additional strong evidence includes photographs documenting property condition issues or defects, independent appraisals from licensed appraisers, repair estimates for significant damage, and documentation of any assessment errors such as incorrect square footage, lot size, or features listed in county records. The Board of Equalization wants to see objective, quantifiable data rather than subjective opinions about your property's value.
What happens at a Board of Equalization hearing in Skagit County?
A Board of Equalization hearing in Skagit County is an informal proceeding that typically lasts about 30 minutes for residential properties. You'll present your evidence showing why your assessed value is too high, then the Assessor's representative will present their case supporting the current valuation. Board members may ask questions of both parties to clarify the evidence. You don't need an attorney and can represent yourself. After the hearing, the Board will issue a written decision within approximately 45 days, either sustaining the current value, reducing it, or in rare cases adjusting it. You should continue paying your property taxes on time during the appeal to avoid penalties and interest.
How much can I save by appealing my property taxes in Skagit County?
In Skagit County, with a median annual property tax bill of $4,008, even a modest reduction in your assessed value can result in significant savings. A 10% reduction in assessed value would save approximately $400 per year, while a 15% reduction would save around $600 annually. These savings continue year after year, though you may need to file a new appeal each assessment year if values continue to be inflated. The actual savings depend on how much your property is overassessed compared to true market value, which is why gathering strong comparable sales evidence is critical to demonstrating the overvaluation.
What is the senior citizen property tax exemption worth in Skagit County?
The senior citizen property tax exemption in Skagit County can provide substantial savings for homeowners age 61 and older who meet income requirements. The program freezes your property's taxable value and exempts you from all excess levies and Part 2 of the state school levy. Depending on your income level, you may also be exempt from 35% to 60% of regular levies. For a property with a median assessed value of $486,200, eligible seniors could save anywhere from $1,500 to $2,800 or more annually depending on their income tier. Applications must be filed with the Skagit County Assessor's Office by December 31 for the following tax year.
Can I appeal to the Washington State Board of Tax Appeals if I disagree with the Skagit County Board of Equalization decision?
Yes, if you disagree with the Skagit County Board of Equalization's decision on your property tax appeal, you have the right to appeal to the Washington State Board of Tax Appeals (WSBTA). You must file your appeal with the WSBTA within 30 days of the mailing date of the County Board's written decision - this deadline is strict with no extensions. The State Board hearing is also informal and doesn't require an attorney. Currently, appeals to the State Board are being scheduled 18-24 months after filing due to a backlog. The State Board will determine whether your assessed value represents fair market value based on the evidence presented.
Does Skagit County offer any property tax relief programs for disabled veterans?
Yes, Skagit County offers property tax exemptions for disabled veterans with service-connected disabilities rated 80% or higher through Washington State's veteran exemption program. The exemption amount ranges from $5,000 to $60,000 depending on your disability rating and income level, with veterans rated 100% disabled potentially receiving a full exemption from regular property taxes on their primary residence. Veterans with a 10-29% disability rating can receive up to $5,000 exemption, 30-49% up to $7,500, 50-69% up to $10,000, and 70-100% up to $12,000. Applications must be filed with the Skagit County Assessor's Office by December 31, and the exemption amounts are adjusted annually for inflation.
