Property Tax Relief

Property Tax/Rent Rebate

The Pennsylvania Legislature enacted a law that expanded the Property Tax/Rent Rebate (PTRR) program to give more Pennsylvanians a rebate and increase the amount of the rebates. The rebate program benefits eligible Pennsylvanians age 65 and older; widows and widowers age 50 and older; and people with disabilities aged 18 and older. The income limit is $35,000 a year for homeowners and $15,000 annually for renters, and half of Social Security income is excluded. The maximum standard rebate is $650, but supplemental rebates for qualifying homeowners can boost rebates to $975.   

Additional information on the PTRR program, including forms, can be found online, or by contacting the Department of Revenue at (888) 222-9190.  

Homestead Exclusion

The Taxpayer Relief Act, Act 1 of Special Session 1 of 2006, allows school districts to reduce property taxes by lowering your property tax bill; the legal term for this is a "homestead" or "farmstead" exclusion. The Act provides for property tax reduction allocations to be distributed by the Commonwealth to each school district. Under a homestead or farmstead property tax exclusion, the assessed value of each homestead or farmstead is reduced by the same amount before the property tax is computed. Every "qualified" homestead within a district receives the same amount of property tax relief, regardless of the assessed value of the home. 

In order to receive a homestead exclusion, you must have an approved application on file with Chester County. The deadline to file annually is March 1. If you miss the deadline in a given year, you may file the following year (but will not qualify for the year you missed). However, once you have an approved application on file, it is not necessary to re-file an application in subsequent years. Please see the application for more information.
