Open Pennsylvania Map →Both. Pennsylvania counties have flexibility in how they handle delinquent tax sales. Philadelphia County holds "upset sales" where deeds are transferred directly to the winning bidder. Allegheny and Delaware counties sell tax lien certificates, where investors earn interest and may foreclose after a redemption period. Always verify the sale type with the county before bidding.
The Philadelphia Bureau of Revision of Taxes (BRT) administers the city's annual upset sale, typically held in the fall. Properties with 3+ years of delinquency are auctioned off. The minimum bid is the total taxes owed. Winning bidders receive a deed, not a lien certificate. A judicial sale follows for properties that don't sell at upset.
Pennsylvania statute sets the interest rate on delinquent taxes at 9% per annum. Allegheny and Delaware county lien certificate holders earn 9% on the face amount of the lien from the date of sale until redemption.
Redemption periods vary by county. Philadelphia's upset sale deed purchasers have a 9-month right of redemption (under certain circumstances). Allegheny and Delaware county tax lien certificates carry an 18-month redemption period before foreclosure proceedings may begin.
Each county manages its own process. Philadelphia BRT publishes its upset sale list at phila.gov/departments/bureau-of-revision-of-taxes/. Allegheny County Treasurer posts the lien sale at alleghenycounty.us. Delaware County Tax Claim Bureau lists sales at delcopa.gov/taxclaim/. Lientac aggregates all three into one searchable map.
