Manage or renew your ROS digital certificate

You must have a digital certificate to access the Revenue Online Service (ROS). You receive a digital certificate when you complete the 3 step ROS registration process.

Who is the ROS digital certificate for?

Individuals, companies and other entities need the ROS digital certificate to access online services for business taxes. It is also required by agents who wish to access online services for their clients.

How to manage or renew your ROS digital certificates

You must renew your ROS digital certificate from time to time for security reasons. We will send you a reminder email when it is time to renew your certificate.

Check that your email address for ROS is up to date in your 'Profile' tab on ROS.

When your digital certificate is due for renewal, you will receive a prompt when you login to ROS. You will be prompted to change your password and ROS Administrators will have to set security questions if not already in place.

Make sure to backup and save your digital certificate when you obtain a new digital certificate or renew your digital certificate.

If you do not renew the certificate, it will expire. The Reset Login option will enable ROS Administrators to download a new ROS certificate where a ROS certificate is lost or expired or the password forgotten.

You can find additional information in  the ROS Help Centre.
