If you hold investments in a trust, receive distributions from a mutual fund, or are named as a beneficiary of an estate, you’ve likely received (or will receive) a T3 slip at tax time. The T3 is one of the more misunderstood tax documents in Canada, partly because the name refers to two different things: a slip you receive as a beneficiary and a return filed by the trust itself. Here’s how it works, what the numbers mean, and what you need to do with it when you file your personal tax return.

The T3 Slip, Explained

A T3 slip, formally called the Statement of Trust Income Allocations and Designations, is a tax information slip issued by a trust to report income that has been allocated to its beneficiaries. Think of it like a T4 slip from an employer or a T5 from a bank, but instead of employment income or interest, the T3 reports income earned inside a trust and passed along to you. Trusts are treated as separate taxable entities under Canadian tax law. When a trust earns income and distributes it to beneficiaries, it issues T3 slips so each beneficiary can report their share on their personal tax return. The trust itself files a T3 Trust Income Tax and Information Return with the CRA, and the T3 slips are part of that filing package. If you’re wondering whether a trust you’re involved with actually needs to file that return, our article on who needs to file a T3 covers the filing requirements in detail.

Who Receives a T3 Slip?

You’ll receive a T3 slip if you’re a beneficiary of a trust that allocated income to you during the tax year. The most common situations include: Mutual fund and investment trust holders. If you hold mutual funds or exchange-traded funds (ETFs) in a non-registered account, the fund trust will issue a T3 slip reporting your share of the fund’s distributed income, which could include interest, dividends, and capital gains. Estate beneficiaries. If a family member passed away and you received income from their estate during the administration period, the estate (which is a type of trust) will issue T3 slips to the beneficiaries. Family trust beneficiaries. If you receive income allocated from a family trust, whether it was set up for income splitting, estate planning, or asset protection, the trustee is required to issue T3 slips for any allocations made to you. Real estate investment trust (REIT) unitholders. Distributions from publicly traded REITs are typically reported on T3 slips. One thing to keep in mind: a trust doesn’t have to issue a T3 slip if the total income allocated to you for the year is less than $100. However, you’re still required to report that income on your return even without a slip.

What’s on the T3 Slip?

The T3 slip contains several numbered boxes, each representing a different type of income or credit. The most common boxes you’ll encounter include: Box 21 – Capital gains. This reports your share of the trust’s taxable capital gains. You’ll use this amount when completing Schedule 3 of your personal tax return. Box 23 – Actual amount of dividends (other than eligible). These are ordinary dividends from Canadian corporations that have been allocated to you. Box 26 – Other income. This is a catch-all box for income that doesn’t fit into the other categories, such as pension income, foreign business income, or retiring allowances. Box 32 – Taxable amount of dividends other than eligible dividends. This is the grossed-up amount of dividends from box 23. You report this amount on your return, and it comes with a corresponding dividend tax credit in box 39. Box 49 – Actual amount of eligible dividends. Eligible dividends from large Canadian corporations carry a higher gross-up and a larger dividend tax credit. Box 50 – Taxable amount of eligible dividends. The grossed-up amount of eligible dividends. The corresponding dividend tax credit appears in box 51. Box 42 – Return of capital. This amount isn’t taxable in the year you receive it, but it reduces the adjusted cost base (ACB) of your investment. Tracking this matters because it affects the capital gain or loss you’ll report when you eventually sell. The CRA’s guide to T3 slip boxes provides a full breakdown of every box and which line of your personal return it maps to.

T3 Slip vs. T3 Return: What’s the Difference?

This is where confusion often creeps in. The term “T3” gets used to describe both the slip and the return, but they serve very different purposes. The T3 slip (Statement of Trust Income Allocations and Designations) is a document issued to beneficiaries showing how much income was allocated to them. It’s what you use to report trust income on your personal tax return. The T3 return (T3 Trust Income Tax and Information Return) is the actual tax return filed by the trust with the CRA. It reports the trust’s total income, deductions, and how income was distributed among beneficiaries. The T3 slips are generated as part of the T3 return filing process. As a beneficiary, you’re responsible for the slip. The trustee or estate administrator handles the return.

When Will You Receive Your T3 Slip?

T3 slips tend to arrive later than other tax slips. While T4s and T5s are typically due to recipients by the end of February, trusts have 90 days after their tax year-end to file the T3 return and issue slips. For trusts with a December 31 year-end, that means T3 slips may not arrive until late March. For mutual fund trusts, the timeline can stretch even further. Complex income calculations, particularly those involving capital gains and foreign income, sometimes delay issuance into April. If you’re preparing to file your personal return and your T3 hasn’t arrived yet, you have a few options. You can check CRA My Account, where T3 slips are posted once the trust files them electronically. You can also estimate the amounts using your account statements and file on time, then request an adjustment later if the actual slip shows different figures. Filing on time matters. The CRA won’t waive late-filing penalties just because a T3 slip was delayed.

How to Report T3 Income on Your Tax Return

Each box on the T3 slip maps to a specific line on your T1 personal tax return or one of its schedules. For most people, the process comes down to a few steps. Dividends (boxes 32 and 50) go on line 12000 of your return. The dividend tax credits (boxes 39 and 51) are claimed on line 40425. Capital gains from box 21 are reported on Schedule 3, after subtracting any amounts from box 30 that relate to capital gains eligible for the capital gains deduction. Other income from box 26 goes on the applicable line depending on its type. If you’re using tax software, the T3 entry screen will handle the line mapping for you. If you’re filing manually, the CRA’s T3 information page for individuals walks through each box and its corresponding line.

Return of Capital: The Detail Most People Miss

Among the various amounts on a T3 slip, return of capital (box 42) catches the most people off guard. A return of capital distribution isn’t income. Instead, it’s a return of part of your original investment. You don’t pay tax on it in the year you receive it. However, it reduces the adjusted cost base of your investment units. If you don’t track these reductions year over year, you’ll miscalculate your capital gain when you sell. In some cases, return of capital can reduce your ACB below zero, triggering a capital gain even without a sale. If you hold investments in trusts over many years, keeping careful records of return of capital adjustments is one of the most important things you can do for accurate tax reporting down the road. Our team can help you track these amounts as part of your personal tax preparation.

Key Takeaways

A T3 slip reports income that a trust has allocated to you as a beneficiary. You might receive one from mutual funds, ETFs, REITs, an estate, or a family trust. The slip arrives later than most other tax documents, often in March or even April, so plan accordingly when preparing your return. Pay close attention to each box number and match it to the correct line on your personal return. Track return of capital adjustments over time to avoid surprises when you sell.
