Bucks County tax-sale bidders face a 4 p.m. Friday registration deadline after the county identified incorrect dates online and in some registration packets.

The Tax Claim Bureau says registration closes Friday, Nov. 13, for the Dec. 8 sales. Its urgent notice says the discrepancy does not affect bidders who have already registered in person.

The bureau says it is trying to notify potential outstanding bidders by email and phone. The posted schedule lists an adjourned upset tax sale and a judicial sale.

People who registered for the September upset sale are automatically registered for both December sales, according to the county. The registration page includes separate packets for individuals, limited liability companies and other entities.

The bureau’s office information lists its location as the fifth floor of 55 E. Court St. in Doylestown. The phone number is 215-348-6274.

The bureau collects delinquent real estate taxes. Its website says it is not accepting cash until further notice.
