Internet security and the CRA

The CRA is committed to providing a secure online environment for Canadians to find information, manage their tax accounts and make payments.

CRA’s security commitment

Our standard for encryption is the Transport Layer Security (TLS) protocol. TLS allows general communication authentication and encryption over TCP/IP networks that transmit data by Hypertext Transfer Protocol HTTP Secure (HTTPS) used by Web servers to transfer and display Web content securely. The data transferred is encrypted so that it cannot be read by anyone except between you and the CRA. This ensures that computer hackers and other Internet users cannot view or alter the data being transmitted

To maximize your security commitment, it is suggested that your computer have current antivirus software, a personal firewall, and that your browser and operating systems be kept up-to-date with all available upgrades.
