How our $199.99 GMTR filing service works

  1. Complete the guided questionnaire above. It walks you through every field the CRA requires for a Global Minimum Tax Return under the Global Minimum Tax Submission Guide.
  2. Authorize payment when you submit. GMTR is $199.99, see pricing. We place a temporary hold on your card at submit; you are only charged after the CRA accepts your filing and returns a confirmation number.
  3. We transmit your GMTR through the CRA's SERS API. Our service is authorized for Pillar Two submissions. The payload is generated in the exact JSON structure the Special Elections and Returns System expects and sent in real time.
  4. Receive your CRA confirmation receipt. Most filings are acknowledged the same day, with the confirmation number returned directly to your browser and emailed to your contact address.

What happens after you submit

You will receive an on-screen CRA acknowledgement and a confirmation number you can quote in correspondence with the CRA. We retain a copy of the payload on your behalf for your records. If the CRA does not accept your filing, the card authorization is released and you are not charged; you can correct your information and resubmit with the same authorization when possible. If the CRA rejects the submission for a technical reason on our end, we will correct and re-transmit at no additional charge. Questions? Contact support@pillar2.info.
