by Intuit Updated 4 months ago

About filing a T3 return

Until 2017, T3s were required to be paper filed, though slips and the summary could be transmitted by XML. starting with 2017 year ends, the T3 could be filed by way of XML filing. Starting in version 2021.3, you're able to to electronically file T3s with regular EFILE credentials.

Note: This article is for filing slips and returns from 2021 and later. If you are looking to file a return from before 2021, see this article.

Available resources

The CRA's Where to file a T3 Return guide details where a T3 return can be filed.

The CRA's T3 Trust Guide provides information on how to complete the T3 Trust Income Tax and Information Return, the T3 slip, Statement of Trust Income Allocations and Designations, and the T3 Summary, Summary of Trust Income Allocations and Designations.

Paper file a T3 return in Profile

ProFile transfers information from the T3 schedules, slips, and forms to the T3 Trust Return Jacket. The final page of the jacket requires a signature from a trustee, executor or administrator for the trust.

Other forms you may need to file if they are used include:

  • T3A: Request for loss carryback by a trust
  • T1013: Consent form
  • T1135: Foreign income verification statement
  • T1141: Information return in respect of transfers or loans to a non-resident trust
  • T2223: Election, under subsection 159(6.1) of the Income Tax Act, by a trust to defer payment of income tax
  • TX19: Asking for a clearance certificate
  • Election: Election to tax income in the trust

Use the T3Efile worksheet

T3Efile is a worksheet used to track exclusions stemming from the T3 return.

T3Efile automatically calculates eligibility and populates (using Yes or No values) based on the return information.

It displays all unmet criteria for filing the T3 return:

A table with a lot of paperwork and a sign.

Any criteria for filing not being met prevents the "Internet file this return?" question in the return's Filing section from activating.

Preparers should review the T3Efile worksheet prior to EFILING and address any unmet criteria prior to filing. If Yes is selected for any of the T3Efile boxes, you may have to paper-file the return.

File T3 slips via XML filing (2021 and later)

EFILE a T3 return with CRA EFILE credentials

Beginning with the release of 2021.3.0, returns with a year end of 2021 or later will be able to be electronically filed using CRA EFILE credentials. Returns are still required to not have any exclusions on the T3Efile worksheet.

A newer section on the Info page under Filing will default to Yes if a T3 is eligible for EFILE and No if not:

The confirmation number will appear on the Info page if successfully transmitted:

Early file next year's T3

The next year’s T3 module in ProFile is not available until the year after: for example, when the 2018 T3 module is the last one released and you need to prepare a T3 return with 2019 year-end, the 2019 T3 module is not available until January of 2019.  In this situation, the previous year’s T3 module is used for preparing next year’s T3 return.

New tax rate implementation

New tax rates are implemented in the previous year’s T3 module to handle preparation of next year’s T3 returns.  Entering the appropriate year-end on the Info page initiates the applicable tax rates for that year. T3 returns filed using the previous year’s tax forms are acceptable to the CRA, and they will reassess the return if required.

Prepare next year’s T3 return using the previous year’s T3 module

  1. Save a duplicate copy of the previous year’s T3 return to be used as the next year’s T3 return.
  2. Open the previous year-end T3 return in ProFile.
  3. Enter the appropriate year-end for the trust return T3 to be prepared; this initiates the applicable tax rates for next year.
  4. Delete the information pertaining to the previous year-end, keeping what is required for the next year-end.
  5. Enter the T3 data required for filing the next year’s trust return, allocate income to beneficiaries, and create the T3 slips.
  6. Print the T3 trust return using File -> Print and print T3 slips using File -> Print Slips.
  7. Save the T3 trust return with a different file name to identify the tax rates for that year.
