Once we have assigned a trust account number to the trust, we will inform you of your trust account number by mail when your T3 APP form is processed. Include this number on all correspondence related to the trust to simplify dealings with us.

If the trust's filing deadline is approaching and you have not been issued a trust account number, do not delay the filing of your T3 return. You must submit your return and any amount owing when it is due to avoid late filing penalty and interest charges.
