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 Franklin County Assessor and Treasurer.
Relief programs
The filing guidance for this county is: December 31, 2025 for the 2026 tax year; Washington's senior/disabled exemption applications and supporting documents are due by December 31 of the assessment year, subject to county acceptance of late applications. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Review county contact informationWashington senior/disabled exemption: generally age 61+ or disabled/qualifying veteran, own and occupy a primary residence, with 2024-2026 maximum combined disposable income of $61,000; exemption reduces eligible levies and freezes taxable value. The deferral threshold is $64,408.
Washington's 1% property-tax limit applies to taxing-district levy revenue, not to an individual parcel's assessed value. The county assesses property at 100% of true and fair market value; individual assessed values can rise or fall with market conditions. Senior/disabled relief and current-use classifications are separate programs, not general valuation caps.
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 calendar days of the Change of Value/valuation notice mailing date, whichever is later; petition to the Franklin 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.
