Quick Answer: The T3 Trust Return Deadline for 2025
- The T3 trust return for the 2025 tax year is due no later than 90 days after the trust's tax year-end.
- For trusts with a December 31, 2025 year-end, which covers most Canadian trusts, the filing deadline is March 31, 2026 (a Tuesday).
- Most non-listed trusts must file the T3 return together with Schedule 15 (Beneficial Ownership Information of a Trust), even when the trust earned no income during the year.
- The Canada Revenue Agency does not expect bare trusts to file a T3 return or Schedule 15 for the 2025 tax year, but this relief does not extend to express trusts, family trusts, or testamentary trusts.
- Late-filing penalties start at $25 per day (minimum $100, maximum $2,500) where no tax is owing, and can climb significantly higher if tax is owed or if the CRA finds gross negligence.
Why March 31, 2026 Feels Like It Is Sneaking Up on Every Canadian Trustee
If you help administer a family trust, an estate, or even a joint property arrangement held for an adult child, you may be staring down a CRA deadline you did not have a few years ago. Since 2023, the rules have widened sharply: most Canadian trusts now have to file a T3 trust return every year, even when the trust earned zero income.
The federal government amended these rules through Bill C-15, which received Royal Assent on March 26, 2026. The Canada Revenue Agency (CRA) is administering the updated rules now, with narrow exemptions and a separate path for bare trusts.
This guide walks you through, in plain English, who must file, what Schedule 15 demands, what missing March 31 actually costs in dollars, and the step-by-step roadmap to file on time.
Quick Start: Pick Your Path
Use the checklist below to identify yourself in under a minute, then jump to the section most relevant to your trust.
- →Family or discretionary trust set up during everyone's lifetime: you almost certainly must file a T3 return and Schedule 15 by March 31, 2026.
- →Testamentary trust or estate created on someone's death: filing is generally required; the deadline depends on your year-end.
- →Graduated rate estate (GRE) in its first 36 months: file a T3, but you are exempt from Schedule 15 as a "listed trust."
- →Bare trust or nominee arrangement (such as a parent on title for an adult child's mortgage): the CRA does not expect you to file for 2025. The picture changes for 2026.
- →Corporate-owned or holding-company family trust: you generally must file both a T3 return and Schedule 15.
- →First-time trustee without a CRA Trust Account Number (TAN): apply now, because processing time can eat into March. See our guide on filing your first T3 return.
Who Must File a T3 Return for the 2025 Tax Year
Under amended section 150 of the Income Tax Act, all express trusts resident in Canada have to file a T3 Trust Income Tax and Information Return unless they qualify for a specific exemption. An express trust is one created intentionally, typically through a written trust deed, will, or court order, to hold property for one or more beneficiaries.
Trusts that escape the filing obligation are called “listed trusts” under paragraph 150(1.2) of the Income Tax Act. The list includes graduated rate estates, qualified disability trusts, registered-plan trusts (RRSPs, RRIFs, TFSAs), employee life and health trusts, registered charities, certain non-profit trusts, and trusts holding $50,000 or less in any combination of assets throughout the year.
Bare trusts sit in their own bucket. On December 16, 2025, the CRA announced that it does not expect bare trusts to file a T3 return (including Schedule 15) for the 2025 tax year. Bare trust reporting is anticipated to begin for 2026, subject to new exemptions in Bill C-15. For a forward look at what 2026 trust filings will look like, see our companion article.
Trust Type vs. Filing Obligation: At-a-Glance Comparison
The table below summarizes the most common trust types Canadian families and SMEs encounter. Confirm your specific situation with a qualified accountant before relying on any single row.
| Trust type | Must file T3 for 2025? | Schedule 15 required? | Typical year-end | Filing deadline |
|---|---|---|---|---|
| Family or discretionary trust (express) | Yes | Yes | December 31, 2025 | March 31, 2026 |
| Testamentary trust (non-GRE) | Yes | Yes | December 31, 2025 | March 31, 2026 |
| Graduated rate estate (GRE) | Yes | No (listed trust) | May be non-calendar | 90 days after year-end |
| Qualified disability trust (QDT) | Yes | No (listed trust) | December 31, 2025 | March 31, 2026 |
| Small-asset trust (FMV $50,000 or less all year) | Yes | No | December 31, 2025 | March 31, 2026 |
| Bare trust (nominee or joint-property arrangement) | Not expected for 2025 (CRA Dec 16, 2025 relief) | No | December 31, 2025 | Not applicable for 2025 |
| Registered-plan trust (RRSP, RRIF, TFSA, RESP, etc.) | No (listed trust, generally exempt) | No | December 31, 2025 | Not applicable |
Step-by-Step Roadmap to File a T3 Return by March 31, 2026
- 1Confirm year-end and filing obligationMost trusts have a December 31 year-end, but a graduated rate estate may have a non-calendar year-end. Watch for deemed year-ends from a change in residency or a beneficiary's death.
- 2Apply for a Trust Account Number (TAN)Electronic filing requires a TAN. CRA processing can take several weeks, so apply by mid-January.
- 3Gather Schedule 15 informationCollect names, addresses, dates of birth, jurisdictions of tax residence, and tax IDs for each trustee, settlor, beneficiary (contingent and discretionary included), and any protector.
- 4Prepare the T3 return and supporting schedulesCalculate income, deductions, allocations to beneficiaries, and tax payable. Watch for capital gains designations and the split between retained versus allocated income.
- 5Issue T3 slips to beneficiariesSlips must reach beneficiaries no later than 90 days after the trust’s tax year-end. Watch for other March and April tax-slip deadlines that often overlap with T3 filing.
- 6File electronically and pay any balanceFile through My Trust Account and pay any balance owing. The CRA considers a paper return on time if postmarked on or before the deadline, but electronic filing is generally faster and safer.
Common Mistakes That Trigger Penalties and CRA Audit Letters
These are the errors ClearWealth sees most often during T3 filing season. Each one is preventable with a few hours of preparation.
- →Assuming no income means no filing. The post-2023 rule is that most express trusts must file annually, whether or not they earned income. File even nil returns by the deadline.
- →Applying for a Trust Account Number in late March. First-time trustees often discover the TAN bottleneck only days before the deadline. Start the TAN application in January, not March.
- →Missing reportable entities on Schedule 15. Contingent beneficiaries, unborn grandchildren, and protectors are routinely overlooked. Review the trust deed line by line before completing Schedule 15.
- →Confusing bare trust relief with general relief. The CRA's December 16, 2025 announcement applies only to bare trusts and only for 2025. Confirm in writing whether your arrangement actually qualifies.
- →Sending T3 slips late or to outdated addresses. Slip-related penalties run separately and can reach $7,500. Confirm beneficiary addresses in January and dispatch slips with the return. Late filings can also trigger preparing for a possible CRA audit.
- →Forgetting the gross-negligence trigger. Filing late with poor records can be reframed by the CRA as gross negligence, opening the door to uncapped 5%-of-FMV penalties. Keep dated trust minutes on file.
- →Overlooking deemed year-ends. A trust that ceases to be resident in Canada or whose beneficiary dies may trigger a deemed year-end mid-year. Ask your accountant whether any 2025 events triggered one.
