NACTP History & Structure

In recognition of the increasing value and need for streamlined income tax preparation, six computerized tax processing firms founded the National Association of Computerized Tax Processors (NACTP) in 1969. Today, the NACTP includes in its membership over 70 tax preparation software companies, electronic filing processors, tax form publishers, tax processing service bureaus and others. NACTP is organized as a nonprofit corporation under ยง 501(c)(6) of the Internal Revenue Code.

The NACTP is made up of three committees which represent the important initiatives of the association: the Government Liaison Committee, the Electronic Filing Committee, and the Payroll and Information Reporting Committee.

The Government Liaison Committee (GLC) addresses issues from both the federal and state agencies, resolving problems and reinforcing information exchanges. This allows the computerized tax processing industry to create high-quality products that can be efficiently processed through each government's system.

The Electronic Filing Committee (EFC) works with the IRS and state taxing agencies, researching and developing the electronic filing process. More returns are filed through this system every year, making it especially important for the links between processor and receiver to be error-free and efficient.

The Payroll and Information Reporting Committee (PIRC) focuses on issues relating to the wage reporting section (both unemployment and withholding) for electronic and paper-based filing. Key objectives of the PIRC are to establish open communication with federal and state agencies, to identify and accomplish mutually beneficial goals, and to facilitate standardization of wage filing systems and processes.
