When to prepare a T3 slip

As trustee, you have to complete Form T3, Statement of Trust Income Allocations and Designations, (T3 slip) for each resident beneficiary, including a preferred beneficiary, to whom the trust allocated income in the year. You must also do this for a trust that made any distributions of capital that would result in an adjustment to the adjusted cost base of the beneficiary's interest in the trust.

You do not have to complete a T3 slip for a beneficiary if the income allocated in the year to that beneficiary is less than $100. However, you have to notify the beneficiary of the allocated income since it still has to be reported on the beneficiary's return.


You have to complete a Form T3SUM, Summary of Trust Income Allocations and Designations, even if you only prepare one T3 slip. This is the form you use to record the total of the more common amounts you reported on all related slips. File only one summary for the trust, unless it is a mutual fund trust.
