Overview

You need a trust account number to file a T3 return.

You may utilize the Trust Account Registration online service before filing electronically.

If you are filing a T3 return on paper you may still use this service to obtain a trust account number.

If we have already 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 are filing a T3 return on paper without a trust account number, ensure to include a completed Form T3APP, T3 Application for Trust Account Number along with your return.

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