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 Union County Assessment Office.

Union County's official page says its prior countywide reassessment became effective January 1, 2006 and assessed values use a 100% predetermined ratio; Pennsylvania has no general annual assessed-value cap. Homestead/Farmstead and Clean and Green are targeted programs, not a general cap.
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: September 1, 2026 for annual assessment appeals; a change-of-assessment appeal may be filed within 40 days of the assessment value-change notice. The Board of Assessment Appeals hears residential, commercial, Clean and Green, Homestead, and tax-exempt appeals. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
