How to Maximize Your Savings
Stack Multiple Exemptions
Many of these exemptions can be combined. For example, you can claim a homestead exemption and a veteran exemption at the same time. Check each exemption's eligibility requirements, and apply for every one you qualify for.
Combine Exemptions with an Assessment Appeal
Exemptions reduce your taxable value, but if the underlying assessed value is too high, you are still overpaying. File for exemptions and appeal your assessment for maximum savings. See our Washington property tax appeal guide for step-by-step instructions.
Do Not Miss Deadlines
Most exemptions have application deadlines. Missing the deadline means waiting another year. Mark the dates on your calendar and file early.

Frequently Asked Questions
Do I need to reapply for exemptions every year in Washington?
It depends on the exemption. Some (like homestead exemptions) are one-time filings that auto-renew. Others (especially income-based exemptions for seniors) require annual renewal. Check the specific requirements for each exemption you claim.
Can I apply for exemptions retroactively?
Some Washington exemptions allow retroactive applications for prior tax years. Check with your county assessor or tax office for the specific rules. In many cases, you can recover 1-2 years of missed exemptions.
What happens to my exemption if I sell my home?
Exemptions tied to owner-occupancy (like homestead exemptions) do not transfer to the buyer. The new owner must apply for their own exemptions. When you buy a new home, remember to file for exemptions at your new address.
How do I know if I am already receiving an exemption?
Check your property tax bill or assessment notice. Exemptions are usually listed as line items. You can also check with your county assessor or auditor to see which exemptions are on file for your property.
