Exemptions & appeals

Senior relief

Okanogan County administers Washington senior/disabled relief for a primary residence or mobile home for owners age 61+ or permanently disabled who occupy the home more than six months. The official county page lists combined income of $41,000 or less and says the exemption amount varies by income.

Valuation limits

Washington's constitutional 1% property-tax limit and the statutory 1% levy limit constrain taxing-district revenue, not an individual parcel's assessed value. County assessors value property at 100% of true and fair market value, so an individual assessed value can rise or fall by more or less than 1%; voter-approved excess levies, new construction, and senior/disabled relief are separate rules.

For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
