Why tax work may remain after the assets are distributed
When a family trust or another trust arrangement is ending, it is easy to treat the asset-distribution date, bank-account closure date, and tax year-end as the same event. They are not necessarily the same. Legal termination, practical asset administration, and income-tax compliance are separate layers, and completing one does not prove that the others are complete.
The CRA's T3 Trust Guide explains that the T3 Trust Income Tax and Information Return functions as both an income tax return and an information return. It reports tax liability, amounts allocated or designated to beneficiaries, and beneficial ownership information when required. A zero account balance or no obvious tax payable does not, by itself, establish that no final filing is needed.
Why did a trust wound up on December 30 still have a December 31 year-end?
Gerald Kowarsky Trust v. The King, 2026 TCC 174 concerned an alter ego trust that wound up its affairs on December 30, 2023. It argued that its final taxation year also ended that day, so it was outside new information-reporting requirements applying to taxation years ending after December 30, 2023.
The Tax Court rejected that interpretation. Paragraph 249(1)(c) of the Income Tax Act made the calendar year the taxation year for this trust. Winding up on December 30 did not shorten the taxation year by one day; it still ended on December 31, so the information-reporting requirement applied. The court upheld the late-filing penalty under subsection 162(7).
According to the published case materials, the required information was eventually provided on Schedule 15 of the T3 return, about eighteen months late. The practical point is that a trust wind-up review must cover both the asset transfers and every component of the final filing.
A useful warning—but not a precedent for every trust
The case proceeded under the Tax Court's informal procedure. Section 18.28 of the Tax Court of Canada Act states that an informal-procedure judgment must not be treated as a precedent for another case. It should not be described as a new rule governing every trust, and it cannot determine the year-end or filing obligations of a different trust without reviewing its facts and governing provisions.
It nevertheless offers a practical warning: for a trust that ordinarily uses the calendar year, winding up during the year or one day before year-end does not necessarily end its taxation year on the wind-up date. Trust type, special rules, governing documents, residence, asset dispositions, and the applicable tax year may change the analysis.
Five items to check before closing a trust file
Before treating the trust as fully complete, build a final T3 checklist:
- Identify the trust type: a family trust, alter ego trust, testamentary trust, graduated rate estate, bare trust, or another arrangement may be governed differently.
- Confirm the final tax year-end: do not automatically use the account-closure or final-distribution date; check the calendar-year rule and any special or deemed year-end.
- Confirm the filings and deadlines: determine whether the trust needs a T3 return, Schedule 15, T3 slips, beneficiary information, and other schedules, using the correct year-end to calculate the due date.
- Notify the CRA: the T3 Guide says that when a trust is wound up or ceases to exist, the CRA should be informed of the date by letter; also review the status of the trust account.
- Preserve the closing file: retain the trust document, trustee decisions, transfer evidence, distribution details, bank and investment statements, disposition records, prior T3 returns, and beneficiary slips.
Completion means the return, records, and asset movements reconcile
If trust assets are being distributed, the trust is about to wind up, or its accounts are already closed but the final T3 and Schedule 15 are uncertain, review the file before concluding that the work is finished. Start with the trust document, latest T3 return, asset list, distribution records, and account-closing documents.
A+ Tax & Estate Advisory can help organize the tax records, asset ownership, distribution history, and remaining filing questions. Legal advice about the validity, amendment, or formal termination of the trust document should come from a qualified lawyer. A trust matter is closer to complete only when its final filing plan is clear and supported by the records.
