How much can I save by appealing my property taxes in Clark County?

The potential savings from a successful property tax appeal in Clark County depend on how much your assessment is reduced. With the county's median home value at $483,900 and an effective tax rate of 0.92%, even a 10% reduction in assessed value could save approximately $445 annually.

The savings continue each year until your next assessment, multiplying the benefit over time.

What evidence do I need for a Clark County property tax appeal?

For a successful Clark County property tax appeal, you'll need strong evidence that your property is overvalued. The best evidence includes comparable sales of similar properties from the last year or two, which you can find through the Assessor's Property Information Center. Professional appraisals, photos showing property defects or needed repairs, contractor estimates for repairs, and documentation of factors limiting your property's use or development are also valuable. Avoid using other properties' assessed values as evidence - focus instead on actual market sales data and physical property conditions that affect value.

Can I appeal my Clark County property taxes if I didn't receive a Notice of Value?

Yes, you can file a preemptive appeal in Clark County between January 1 and July 1 of any assessment year, even without receiving a Notice of Value. This allows you to appeal if you believe your property is overvalued based on current market conditions. Once you receive your actual assessed value, you can update your appeal, add evidence up to 21 business days before your hearing, or withdraw it if satisfied. This preemptive option ensures you don't miss the opportunity to appeal while waiting for your notice.

What if I disagree with the Clark County Board of Equalization's decision?

If you disagree with the Clark County Board of Equalization's decision, you have the right to appeal to the Washington State Board of Tax Appeals within 30 calendar days of the County board's decision mailing date. You'll need to file a separate appeal form with the state board, available on the county's documents page.

Remember that you must still pay your property taxes by the due dates to avoid penalties and interest, even while your appeal is pending.
