The T3, Statement of Trust Income Allocations and Designations, is the slip a trust uses to report the income it allocates to its beneficiaries for the year. Mutual fund trusts, estates, and personal trusts all issue T3 slips. If you hold mutual funds in a non-registered account or are the beneficiary of an estate, you may receive a T3 showing amounts you must report on your T1 return. The slip is prepared and filed by the trustee or administrator, not by the beneficiary.
Trustees and estate administrators can open the T3 slip in the Universal PDF editor, complete the trust, beneficiary, and allocation details on screen, and download a finished PDF for filing records and beneficiary copies.
What is the T3 used for
A trust that earns income and allocates it to beneficiaries reports those allocations on T3 slips so each beneficiary knows what to include on their own return. The slip preserves the character of the income: capital gains, dividends, interest, and other income each appear in their own boxes, because they are taxed differently in the beneficiary's hands.
For everyday investors, the most common source of a T3 is a mutual fund trust or exchange-traded fund that distributed income during the year. For families, T3 slips often arise from an estate that earned income before it was fully distributed.
Who files the T3
The trustee, executor, or administrator files the T3 slips together with the trust's T3 return, subject to the requirements in the official instructions. Beneficiaries do not file the slip; they use it to complete their own return.
T3 slips and the related return are generally due within 90 days after the end of the trust's tax year. Because many trusts have a December year end, beneficiaries often receive T3 slips later than T4 and T5 slips, sometimes close to the end of March.
How to fill out the T3
For trustees preparing slips, the core elements are:
- Trust identification: the trust's name and account number as registered with the CRA.
- Beneficiary identification: name, address, and social insurance number or business number.
- Capital gains: the beneficiary's allocated taxable capital gains, in the box the official guide specifies.
- Dividends: actual and taxable amounts of eligible and other-than-eligible dividends, with the related credit boxes.
- Other income: interest and other amounts allocated to the beneficiary that do not fit the specific categories.
- Footnotes and designations: any designations the trust makes, entered as the official T3 guide directs.
Where to send it
Trustees file T3 slips with the CRA as part of the trust's annual filing, using the methods set out in the official instructions, and give each beneficiary a copy. Beneficiaries keep the slip and report the amounts on their T1 return.
Frequently asked questions
T3 slips are generally due within 90 days after the trust's year end rather than the end of February, so slips from mutual funds and estates often arrive in late March.
A T5 reports investment income paid directly to you, such as bank interest and corporate dividends. A T3 reports income allocated to you by a trust, such as a mutual fund trust or an estate.
You report the amounts in the boxes according to their type. Different boxes are taxed differently, and some designations affect how you claim credits, so follow the official guide or consider a tax professional for complex allocations.
If the estate earned income that was paid or payable to beneficiaries, T3 slips and a T3 return are generally required. The official instructions explain the filing conditions and deadlines.
No. The trustee files it. Beneficiaries keep their copy and use the amounts to complete their own return, attaching it only if they file on paper and the instructions ask for it.
