Certified Service Providers

​The Department of Revenue is working with Certified Service Providers (CSPs) to make it easier for individuals and businesses with sales tax collection obligations in Pennsylvania to comply with the law.

Under this arrangement, any remote seller who does not have physical presence in Pennsylvania can outsource most of their sales tax administration responsibilities to a CSP. For example, a CSP will facilitate the registration process, file tax returns and collect and forward tax payments to the department on behalf of its clients.

A CSP can also help remote sellers of products on the Internet determine which products are subject to Pennsylvania sales tax, easing the compliance burden further. Moreover, working with a CSP can relieve the seller of certain liabilities upon audit.

The department issued an Invitation for Bid as part of a procurement of CSPs willing to perform these services for clients with sales tax collection obligations in Pennsylvania. Below are the four companies the department procured to perform sellers’ sales tax functions at free or reduced cost:





As a reminder, effective July 1, 2019, remote sellers who have no physical presence but whose direct sales in Pennsylvania exceed $100,000, must register to collect and remit Pennsylvania sales tax. Visit the department’s Pennsylvania Sales Tax and Economic Presence web page for further information.

If you are an online seller who prefers to file tax returns and remit Pennsylvania sales tax directly to the Department of Revenue, you need to register for a sales tax license. Visit to fill out the PA-100 Pennsylvania Enterprise Registration Form.
