Business Privilege and Mercantile Tax Failure to File Mailings

Keystone has mailed business privilege/mercantile tax failure to file notices to active and operating businesses that did not file a business privilege/mercantile tax return in tax year 2024.

Business privilege/mercantile tax cannot be filed or paid online. This tax must be filed using the form for your particular jurisdiction available on Keystone’s Forms page. Payment of tax must be supplied with the filed return and supporting documentation.

If your business received a business privilege/mercantile failure to file tax notice, but you do not believe you owe the tax, complete the back of the tax notice and return to:

Keystone Collections Group

PO Box 489

Irwin, PA 15642
