CSA on the net

CSA on the net allows you quickly and securely apply for or cancel children's special allowances (CSA) online.

• You can apply for or cancel CSA from your own location.
• Your applications and cancellations are immediately updated on the Canada Revenue Agency's (CRA) mainframe server.
• In most cases, no manual intervention is required, so we can process your application and issue your payment more quickly.
• The appropriate adjustments are reflected in the following month's payment.

Security

We will issue your organization a unique public key infrastructure (PKI) certificate. Our state-of-the-art security measures ensure your data's confidentiality both while it is being transmitted to us and when it is stored on our servers.

• We use the Government of Canada's PKI to encrypt your data. This ensures that no one else can access the data as it securely travels between your computer and our servers.
• As an eligible CSA recipient, you will undergo a thorough security check before we will authorize and authenticate you as a new CSA on the net user.

We will revoke any certificate if its integrity has been compromised.

Two ways to file electronically

Choose the method that works best for your organization from our two options for fast and secure electronic filing.

• Secure CSA on the net website: using its assigned user ID and password, your agency can access our secure website to complete and submit an application or cancellation. Your data is validated and automatically encrypted before it's sent to us.
• SFTP (secure file transfer protocol): your agency creates, encrypts, and digitally signs a data file containing CSA applications and cancellations. SFTP is used to transfer the encrypted file to the CRA's secure servers.

When you are ready to register, or for more information about either of our two electronic filing options, please call our toll-free CSA on the net line at 1-877-418-7714.
