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 Delaware County Board of Assessment.
Relief programs
The filing guidance for this county is: Delaware County's official Property Taxes page provides Homestead Status and Tax Records resources, but the 2026 local homestead application deadline was not published on the reviewed page. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationPennsylvania Property Tax/Rent Rebate Program: eligible homeowners and renters age 65+, widows/widowers age 50+, and people with disabilities age 18+ may qualify; 2025 household income limit is $48,110, with standard rebates up to $1,000. Applications for 2025 taxes are due December 31, 2026. Official information: https://www.pa.gov/agencies/revenue/ptrr
Delaware County does not publish a general annual assessed-value cap; the 2026 county tax-deferral program can defer millage-increase-related tax increases for eligible owners, and assessments use the Pennsylvania common-level-ratio system.
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: August 1, 2026 for annual appeals for the following tax year; interim appeals are due within 40 days of the assessment-change notice; exemption appeals use the applicable preceding-year deadline. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
