What You Should Know About Allegheny County Property Tax Assessments

Allegheny County uses a base year methodology for property tax assessments. This methodology means that your property’s assessed value is not affected by changing market conditions. The base year methodology also allows similar assessed values for similar homes. 

As the last county-wide reassessment was done in 2013, your property will be reassessed only in the following cases:

  • Errors or omissions
  • Physical changes, i.e., demolitions or constructions of any kind 
  • Situations when a school district or municipality asks for an interim assessment on new buildings or significant improvements
  • Past assessment appeals

Homeowners or taxing bodies can appeal an assessment of the property annually. 

If you’re thinking about making notable changes to your home, you should be aware you’ll need to apply for building permits. This may trigger the reassessment of your property’s value when you implement all the changes.
