In order to maintain the integrity of our tax programs and the security of our systems, the Canada Revenue Agency does not post API documentation publicly. This information is only released to vetted tax software development companies who have met the CRA’s stringent requirements.

If the requirements are met, the applicant is required to sign several legally binding agreements that cover various aspects of the NETFILE and EFILE certification process.
