The National Association of Computerized Tax Processors (NACTP) is a nonprofit association that represents tax processing software and hardware developers, electronic filing processors, tax form publishers, tax processing service bureaus and payroll processors.

The association promotes standards in tax processing and works closely with the IRS, SSA, State and Local governments to promote efficient and effective tax filing. The association also advocates private sector solutions to government tax processing technology requirements.

A joint goal of the NACTP and government taxing agencies is to provide the best possible service to taxpayers. The NACTP is dedicated to achieving that goal by providing expertise in and knowledge of software systems to assist government agencies in implementing new technologies. By working together, this goal can be achieved.
