CSA on the net

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

• 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 and confirm your payment more quickly.
• The appropriate adjustments are reflected in the following month's payment.

Security

We will issue your organization a unique 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 public key infrastructure (PKI) to encrypt your data. This means 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 whose integrity appears to have been compromised in any way.

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 web site: using its assigned user ID and password, your agency can access our secure web site to fill in and file an online application or cancellation form. Your data is validated and automatically encrypted before it's sent to us.
• FTP (file transfer protocol): your agency creates, encrypts, and digitally signs a data file containing CSA applications and cancellations. FTP is used to transfer the encrypted data file to the CRA's secure servers.

How to register

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