Application for a Trust Account Number – Overview

Overview

You don’t need to apply for a trust account number before filing a T3 return on paper. However, you do need to apply for a trust account number before filing electronically.

The CRA will issue account numbers, if you don’t already have one, for all T3 returns filed. We will show your account number on the notice of assessment.

If we have assigned an account number to the trust, enter it in the trust account number space on the T3 return. Include this number on all correspondence and payments related to the trust.

If you have not applied for a trust account number before filing your return, leave the trust account number space on the return blank. You will have to file the return on paper.

If this is the first return filed for the trust, answer “yes” to this question on the return.
