Request your Digital Access Code (DAC) — free

A Digital Access Code (DAC) is required by the CRA before you can file a GIRN, GMTR, or GIR through the Special Elections and Returns System (SERS) API. Enter your GMT entity details below and we will retrieve your DAC directly from CRA — at no charge.

Need to file after you get your DAC? See File GIRN or pricing for all return types.

What is a CRA Digital Access Code (DAC)?

A Digital Access Code is a one-time credential issued by the Canada Revenue Agency that authenticates your organization before a Pillar Two electronic filing is transmitted. The CRA verifies your PT program account number, the calendar year of the filing, and three shared secrets tied to the GMT entity on record: its legal name, registration date, and postal or ZIP code. When all values match, the CRA returns a DAC you embed in your GIRN, GMTR, or GIR payload.

When do I need to request a DAC?

Request your DAC before you begin filling in any CRA return form. DACs are year-specific: you need a new DAC for each filing year. Pillar2 Pathway will automatically embed the DAC you receive here into your GIRN or GMTR filing if you proceed to file on this platform.
