91. Why does a trust preparer need information about people who received no money?
When Schedule 15 is required, the reporting can cover trustees, settlors, beneficiaries and controlling persons, rather than only people who received distributions. Names, addresses, dates of birth where relevant, residence and tax identifiers may be required. The trust type, tax year and applicable exceptions must be checked first. A zero distribution is not itself a reason to omit a reportable person.
First step: Create a current list from the trust documents and use the agreed secure method for sensitive details.

92. Can I file an estate’s electronic T3 using the deceased person’s SIN?
The estate or trust needs its own trust account number for electronic T3 filing. The deceased person’s SIN serves a different purpose and does not replace that account. CRA offers trust-account registration online or through Form T3APP, with supporting documentation. If a number already exists, use it rather than creating another account for the same trust.
First step: Locate previous T3 assessments or obtain the account number before the filing process begins.

93. What changes if an estate beneficiary lives outside Canada?
Certain estate or trust income paid or credited to a non-resident can require Part XIII withholding, remittance and NR4 reporting. The income type and any applicable treaty affect treatment. A non-resident address is therefore important before payment, not only when preparing slips later. Capital distributions and income distributions should not be treated as interchangeable.
First step: Confirm each beneficiary’s tax residency and the nature of the intended payment before releasing it.

94. What if the T3 filing deadline arrives before an investment slip?
Do not assume a missing slip extends the deadline. CRA instructs trustees to estimate required income when necessary and request an adjustment if the final information differs. First confirm which income belongs to the trust’s fiscal period; a calendar-year investment slip cannot always be divided mechanically by months. Keep the calculation and obtain the missing information promptly.
First step: Give the preparer transaction statements and the trust’s exact year-end, and track the later reconciliation.

95. Does correcting a beneficiary’s T3 slip also correct the trust’s return?
Not automatically. An amended slip may require an amended T3 Summary, and changes affecting the trust return or Schedule 9 need a T3 adjustment request or explanatory letter. Send the beneficiary the corrected slip and identify what changed. Reissuing the original return without the appropriate adjustment process can create confusion.
First step: Reconcile the original and revised slips, summary and return before submitting the corrections.

96. What is a trust’s 21-year tax anniversary?
Many trusts face a deemed disposition of relevant property after 21 years, with exceptions and different triggering dates for certain trust types. Tax can arise without an actual sale. The relevant anniversary must be calculated from the trust’s own history, not simply the beneficiary’s age. Planning close to the date can leave little time to evaluate lawful options.
First step: Find the signed trust deed, creation date, prior deemed dispositions and current asset values well in advance.

97. Is a trust’s province decided only by the trustee’s mailing address?
No. CRA looks at where the trust’s central management and control actually takes place. A trustee’s address can be relevant but does not always determine residence. Multiple decision-makers or a move across borders can complicate the analysis. The practical conduct of the trust matters alongside the written deed.
First step: Record who makes substantive decisions, where those decisions are made and any changes during the year.

98. Does a family trust get the same tax brackets as an individual?
Ordinary trusts generally face the highest federal individual rate on taxable income retained in the trust, with provincial tax also relevant. Graduated rate estates and qualifying disability trusts are important exceptions with conditions. Special trust regimes can differ. A trust is not automatically a low-tax account for family income; distributions and beneficiary taxation require a separate review.
First step: Confirm the trust type and elections before estimating tax on retained income.

99. Can an estate or trust file its T3 online?
Yes, eligible T3 returns can be transmitted through T3 EFILE using software certified for the relevant year. Exclusions apply, including amended T3 returns and returns without a trust account number. For an initial return transmitted through this service, the trustee, executor, liquidator or administrator must complete and sign Form T183TRUST before transmission. Keep the filing confirmation with the estate or trust records.
First step: Confirm the tax year, trust account number and EFILE eligibility, then review the prepared return and authorization before filing.

100. When can the trustee mark a T3 as the final return?
The trust must actually have ceased to exist; an intention to finish soon is not enough. Confirm the wind-up, distributions and any remaining property or income before selecting the final-return indicator. The relevant tax year-end and filing deadline depend on the trust type. A final T3 also does not replace a separate clearance-certificate review where one is needed.
First step: Reconcile the closing ledger, outstanding receipts and final distribution date with the trustee before filing.
