Updated: 29-Jan-2019 New Automated Tax Compliance Verification Process  

The Ontario Government has automated the mandatory Tax Compliance Verification (TCV) process for businesses bidding on provincial contracts valued at $25,000 or above.


Effective September 14, 2018, service providers registered with the Ministry of Transportation’s Registry, Appraisal and Qualification System (RAQS) are required to confirm compliance with provincial tax obligations, including those federally administered for Ontario, using a new self-serve portal. The TCV portal replaces the existing Tax Compliance Declaration Form and allows service providers to check their compliance status at any time online, and obtain a TCV number to provide to procuring ministries.


Service providers in RAQS are required to complete a TCV at the time of registration and on an annual basis.  Tax compliance verification is required to be eligible to bid on MTO contracts.


Getting a Tax Compliance Verification (TCV) Number

Before you can verify your tax compliance status, your business will need to have a One-key ID. Visit One-key Account Registration to set up an account.


  1. To get your TCV number: Register for E-Services
  2. Select e-Services from My Services
  3. Select or Add a Business on the e-services page
  4. Select TCV (you will be redirected to the portal)
  5. In the portal, select Request TCV Number on the TCV page

  7. Select View Summary to review compliance summary

  9. Provide your email to receive alerts about your account status


After completing the steps above, service providers can submit their TCV number and a copy of their FBC letter to MTO Qualification Control as part of their RAQS initial registration or annual renewal.
