The Internal Revenue Service has a continuing need to have an Electronic Credit Card Payment Program that allows taxpayers to pay their federal tax liabilities by means of Interactive Voice Response (IVR), Internet or mobile device. The Electronic Credit Card Payment Program's mission is to offer convenient, safe, and secure payment methods that allow taxpayers to electronically pay individual and business taxes. The current credit card payment program is a key tax payment method that encourages and reduces paper handling for the service. The credit card program supports IRS and Wage and Investment (W&I) Strategic goals of promoting paperless filing and enables taxpayers to conduct transactions electronically with the IRS. The contractors capture taxpayer card and payment information, obtain real time authorization of the line of credit, provide taxpayers with a confirmation number at the end of the transaction and transmit files to a Treasury Financial Agent as required by the Electronic Federal Tax Payment System (EFTPS) Credit Card Bulk Provider Requirements.
