When Do Property Tax Bills Come Out in Washington? Key Dates and Deadlines
TL;DR
Washington assessment notices arrive February through April. The appeal deadline to the county Board of Equalization is July 1 (or within 60 days of the change of value notice, whichever is later). Tax bills are due in two installments: April 30 and October 31. Washington has no state income tax, so property taxes carry extra weight. The average effective rate is about 0.84%, but bills can be substantial due to high home values, especially in the Seattle metro area.
Most guides on when Do Property Tax Bills Come Out in Washington? Key Dates and Deadlines skip the details that matter. Washington assesses property at 100% of true and fair market value.
If your deadline has already passed, check whether your state has a secondary appeal window. Some states allow filing with a higher court or board after the initial deadline. If no secondary option exists, start preparing now for next year's appeal so you are ready the moment your next notice arrives.
Washington Property Tax Calendar
| When | What Happens | Your Action |
|---|---|---|
| January 1 | Assessment date | Values set as of this date |
| February-April | Change of value notices mailed | Review immediately |
| April 30 | First half tax payment due | Pay |
| July 1 | Board of Equalization petition deadline | File if overassessed |
| October 31 | Second half tax payment due | Pay |
Deadlines in property tax are not flexible. Miss the filing window by even one day and you lose your right to appeal for the entire year. That is another 12 months of overpaying with no recourse. As soon as you receive your assessment notice, find the deadline and mark it on your calendar with a reminder set for two weeks before.

Washington Assessment System
Washington assesses property at 100% of true and fair market value. The county assessor revalues all property annually based on market conditions and comparable sales data.
You receive a "Change of Value Notice" when your assessed value changes. If the value stayed the same, you may not receive a notice. Check your county assessor's website to verify your current value regardless.
Understanding this topic fully means looking at both the big picture and the specific details that apply to your situation. Every property is different, and the strategies that save the most money are the ones tailored to your particular home, location, and circumstances.
Start by gathering the basic facts about your property: its assessed value, the tax rate in your jurisdiction, and any exemptions currently applied. Then compare your situation to what is available. You may find opportunities for savings that you did not know existed.
How to Appeal in Washington
Step 1: County Board of Equalization
File a petition with the county Board of Equalization by July 1 or within 60 days of the value change notice, whichever is later.
The petition should include:
- Your property description and parcel number
- Current assessed value
- Your opinion of value and the basis for it
- Comparable sales data
The Board of Equalization holds a hearing and issues a decision. Most hearings are informal and last 15-30 minutes.
Step 2: State Board of Tax Appeals
If the county board denies your petition, you can appeal to the Washington State Board of Tax Appeals within 30 days. This is a more formal process.
The appeal process is designed to be accessible to regular homeowners, not just attorneys and tax professionals. You do not need to hire anyone to file. The key is preparation. Gather your evidence before the hearing, organize it clearly, and practice presenting your case in under 10 minutes. Lead with comparable sales, then cover any property record errors, and finish with photos or documentation of condition issues.
Keep your tone professional and factual. Review boards respond to evidence, not complaints. If you walk in with 3 strong comparable sales and a calm, organized presentation, you are already ahead of most appellants.
Washington Exemptions
| Program | Benefit | Eligibility |
|---|---|---|
| Senior/disabled exemption | Partial or full exemption depending on income | Age 61+ or disabled, income under limit (adjusted annually) |
| Senior/disabled deferral | Defer taxes until property is sold or ownership transfers | Age 60+ or disabled, income under limit |
| Disabled veteran exemption | Reduction in assessed value | Veteran with 80%+ service-connected disability |
Washington's senior exemption is income-tiered. Higher income levels receive partial exemptions, while the lowest income levels receive full exemptions from regular levies. Apply with your county assessor by December 31 for the following year.
Do not assume you are automatically enrolled. Most exemptions require an application, and many homeowners lose years of savings simply because they never filed. Contact your county assessor's office or check their website for the application form. Bring proof of eligibility (age verification, disability documentation, veteran status, etc.) and file well before the deadline.
If you qualify for multiple exemptions, apply for all of them. In most jurisdictions, exemptions stack. A senior homeowner who is also a veteran can often claim both exemptions simultaneously, doubling the savings.
Washington Tax Rates and No Income Tax
Washington is one of a handful of states with no income tax. This means property taxes are a larger portion of the overall tax burden for residents. The average effective property tax rate is about 0.84%, but with median home values over $600,000 in the Seattle metro area, annual tax bills commonly exceed $5,000.
Property tax rates in Washington are set by levies approved by voters and governing bodies. The total rate is a combination of state, county, city, school district, fire district, library, port, and other special district levies.

Your Next Steps
Here is what to do right now:
- Check your state's deadline. Use the tables above to find your state's specific dates. If your deadline is within the next 60 days, start preparing immediately.
- Open your assessment notice. If you received one recently, read it today. Do not set it aside. Check the assessed value, property details, and the appeal deadline printed on it.
- Gather comparable sales. If your assessed value looks too high, pull 3 to 5 recent sales of similar homes in your area. This is the single most important piece of evidence for any appeal.
- File for exemptions you have not claimed. Many homeowners miss exemptions simply because they never applied. Check what is available in your state and file before the deadline passes.

Frequently Asked Questions
Can my value increase more than 1% per year?
Washington law (RCW 84.55) limits the total revenue a taxing district can collect to 1% growth per year (plus new construction). This is a limit on total revenue, not individual assessments. Your individual assessment can increase more than 1% based on market value changes.
What if I did not receive a change of value notice?
If your value did not change, you may not receive a notice. Check your county assessor's website to see your current value. If it changed and you were not notified, contact the assessor's office about your appeal rights.
