Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Chelan County Assessor; Chelan County Treasurer collects property taxes.
Relief programs
The filing guidance for this county is: April 30, 2026 for Washington senior/disabled property-tax exemption applications; Chelan County's official exemption page provides the program contact and application information. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Review county contact informationChelan County's Senior/Disabled program reduces property tax for a qualifying primary-residence owner age 61+ or a qualifying disabled person; the county's current program page lists household income under $48,000 and directs applicants to the exemption administrator at 509-667-6364.
Washington's 1% levy-revenue limit does not cap an individual parcel's assessed value. Chelan County annually updates values from market sales and assesses taxable property at 100% of fair market value; senior relief and current-use programs are separate.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: July 1, 2026 or within 30 days of the mailing date printed on the Notice of Value, whichever is later, for the Chelan County Board of Equalization. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
