How Pennsylvania Tax Sales Work

Pennsylvania tax sales are deed sales. A September upset sale leaves recorded mortgages standing, and only a judicial sale clears them.

By Evan Reid, Founder of Tax Sale Atlas · Updated Aug 9, 2026 · 6 min read

Pennsylvania sells the property. No county issues a tax lien certificate, so there is no rate to bid and no paper to hold. It runs a two-rung ladder instead, an upset sale then a judicial sale, and the rungs hand you completely different title.

County bureaus, platforms and dates sit on the Pennsylvania tax sales hub, and how to buy tax deeds in Pennsylvania walks the sequence. The governing act is 72 P.S. 5860.101 et seq., the Real Estate Tax Sale Law of 1947. If the structures still blur, read tax liens compared to tax deeds.

Step 1: The claim goes absolute before a Pennsylvania tax sale

Taxes are delinquent on December 31 of the year they were due. The collector returns the unpaid list to the county Tax Claim Bureau by April 30, and interest then runs at 9 percent a year, all of it to the taxing districts and none to an investor. The bureau notices the claim by July 31, it goes absolute the next January 1, and the parcel reaches the upset sale that September, roughly 21 months after delinquency.

Step 2: Register in person, at least ten days out

Act 33 of 2021 added the rule that catches out-of-state buyers. Section 501-A requires you to appear and register at the bureau no less than 10 days before each scheduled sale. Nobody bids by walking in on sale day. The application names every officer and manager of an entity bidder and swears you owe no delinquent property taxes in the Commonwealth, no municipal utility bill over a year old, and no uncorrected housing code violation after a conviction in the last three years.

Step 3: The September upset sale and its floor price

Section 601 puts the upset sale no earlier than the second Monday of September and before October 1, and any continuation must be held inside the calendar year. Advertising and certified restricted-delivery mail to owners run at least 30 days ahead, and posting at least 10 days ahead.

Section 605 fixes an upset price and forbids any sale below it: Commonwealth tax liens, the claim absolute and its interest, other tax claims and judgments, all accrued taxes, municipal claims, and the record costs of sale. Districts certify by August 30, and a municipal claim that arose before August 1 and went uncertified is divested.

Step 4: What an upset sale leaves standing

Here is the trap. Section 609 conveys an upset-sale property subject to every recorded obligation, lien, estate, mortgage and ground rent the upset price did not include. A first mortgage can walk straight through the auction and land on the winning bidder.

The upset price measures your minimum outlay rather than the parcel's true cost. Order a title search and add the surviving encumbrances to your bid. What survives a tax deed covers the pattern, due diligence before a tax sale covers the search, and the tax deed max bid calculator carries Pennsylvania's cost rules.

Step 5: The judicial sale is the clean one

When no bid meets the upset price, the bureau petitions the court of common pleas under section 610. Section 612 has the court order the property sold free and cleared of all tax and municipal claims, mortgages, liens, charges and estates, except separately taxed ground rents. That is why judicial-sale prices run above upset prices.

A judicial sale sets no upset price, though the order may require a bid covering the earlier costs plus this sale's own. Section 616 forces the petition: 10 months after the upset sale with nothing filed, the bureau has two months to file.

Step 6: Same-day money, then a court confirms

Section 606 requires the upset-sale purchaser to pay the entire purchase money on the day of the sale, no later than one hour before the close of business, or the sale is voided. The act sets no deposit, no buyer's premium, and no payment window for judicial sales, so county terms govern there.

Then the court. The bureau returns the sale within 60 days, the court confirms nisi within 30 days, and objections run 30 days after that before absolute confirmation. An objection may attack how the bureau ran the sale, never the legality of the taxes. Your title is not settled at the hammer.

Step 7: Redemption ends at the sale, except in two counties

Section 501(c) is blunt: there is no redemption of any property after the actual sale. The owner's last opening is to discharge the claim beforehand, and a county that adopted the section 502.1 option may extend that window on owner-occupied homes by up to 12 months on hardship.

The act defines "County" to exclude the first and second class, so Philadelphia and Allegheny sell through sheriff's sales under the Municipal Claim and Tax Lien Law of 1923, which keeps a live redemption right under section 32. A redeemer repays the sale price, deed costs, taxes and claims paid, undischarged encumbrances paid, and necessary expenses less rents, plus 10 percent a year on each payment. Nobody redeems vacant property once the deed is acknowledged. Bucks, Delaware and Montgomery are second class A and stay inside the act.

The redemption position in one line: None after the sale in the 65 Real Estate Tax Sale Law counties; in Philadelphia, 9 months from acknowledgment of the sheriff's deed, and 3 months in Allegheny County and Pittsburgh. Compare it in redemption periods explained.

Buying what nobody bought

Anything unsold after a judicial sale drops into the county repository under section 626, and the bureau must keep that list public. With every taxing district's written consent it may set a floor price and take any offer at or above it without court approval; a district silent for 60 days consents by default. Repository deeds read free and clear like a judicial sale. Section 613 adds a private-sale route for parcels that drew no upset bid, open to a court price challenge for 45 days. Former owners cannot buy back this way. Over-the-counter tax liens shows how leftover inventory differs by state.

Putting it together

Pennsylvania rewards buyers who know which rung they are on. An upset sale is cheap because it is dangerous, and a judicial sale costs more because a court cleaned the title first. Register in person ten days out, pull title before any upset bid, and bring same-day certified funds. Transfer tax runs on assessed value times the county common level ratio factor under 61 Pa. Code 91.135, never on your bid. Budget for quiet title after a tax deed before counting on a resale, and start parcel work in the Pennsylvania county directory.

Frequently asked questions

Does Pennsylvania sell tax liens or tax deeds?
Tax deeds. In the 65 counties under the Real Estate Tax Sale Law the Tax Claim Bureau sells the property, at a September upset sale and then a court-ordered judicial sale.
What is the difference between an upset sale and a judicial sale?
Title. An upset sale conveys the property still subject to every recorded mortgage, lien, ground rent and estate the upset price did not cover. A judicial sale conveys free and cleared of them, except separately taxed ground rents.
Is there a redemption period after a Pennsylvania tax sale?
Not in the 65 Real Estate Tax Sale Law counties, where section 501(c) allows none after the actual sale. Philadelphia and Allegheny County sell under the Municipal Claim and Tax Lien Law, where redemption runs nine months from acknowledgment of the sheriff's deed, three months in Allegheny, and never for vacant property.
How do you register to bid at a Pennsylvania tax sale?
In person at the county Tax Claim Bureau, no less than 10 days before each scheduled sale. The application discloses an entity bidder's officers and swears to clean standing on taxes and utility bills.
When do you pay at a Pennsylvania upset sale?
The same day. The purchaser pays the entire purchase money on the sale date, no later than one hour before the close of business.
Can you buy Pennsylvania tax properties over the counter?
Yes, from the county repository for unsold properties. With every taxing district's written consent the bureau may set a floor price and take any offer at or above it.
