Exemption and abatement requests

Nonprofit and governmental property exemption requests use a specific application and service requirements. Homestead/Farmstead and other abatement programs have separate rules. Do not use a generic exemption label without identifying the exact program.

Tax and land-record checks

The assessment portal includes tax information, but use the County Treasurer for the current county-tax account. Recorded deeds, mortgages and satisfactions must be searched through land records. A base-year assessment and a current market estimate are not the same figure.

How to Verify the Exact Allegheny County Account

Start with the official search portal at realestate.alleghenycounty.us. Begin with the identifier printed on the notice, bill or deed. If the first query fails, use the owner or street address and copy the identifier from the matched record instead of inventing a format.

  1. Confirm the situs or property location and do not confuse it with the owner’s mailing address.
  2. Match the legal description, subdivision, lot, block, survey, abstract or other local land identifier.
  3. Compare land area, property class and improvement description with the physical property.
  4. Check the valuation year and whether the amount is preliminary, current, certified or already billed.
  5. Open the map at realestate.alleghenycounty.us for location context, then rely on recorded documents and a survey for legal boundaries.
  6. Look for related real, personal, mineral, mobile-home or business accounts before assuming the search is complete.
Boundary warning: a GIS line can be generalized or shifted. It is not a survey, title commitment or legal access opinion.
