Version 1.0 – New Forms

Federal

T5013 Schedule 130, Partnership Interest and Financing Expenses and Interest and Financing Revenues (Jump Code: T5013S130)

The excessive interest and financing expenses limitation (EIFEL) rules limit the deductibility of interest and financing expenses by affected corporations and trusts. The rules apply to tax years starting on or after October 1, 2023. The main provisions for these rules are paragraph 12(1)(l.2), sections 18.2 and 18.21 and clause 95(2)(f.11)(ii)(D) ITA.

The new Schedule 130 is used to determine the allocation of interest and financing expenses or income to members of a partnership. The schedule must be completed if a partnership has a corporation or a trust as a member or deemed member under subsection 18.2(12) as well as interest and financing expenses or interest and financing income during the fiscal period.

However, if certain conditions are met, the partnership may be exempted from filing Schedule 130. For more details, please consult the Canada Revenue Agency’s website.

Amounts reported and allocated to members on Schedule 130 will be transferred to boxes 247 to 250 and 253 to 256 of Form T5013/RL-15 (Jump Code: T5013).

 

Québec

RLZ-11.P, Payment Relating to the Renunciation of Expenses or the Allocation of Assistance by a Corporation (Jump Code: RLZ11P)

This new remittance slip must be used when there is a balance payable on Form Renunciation of Expenses or Allocation of Assistance by a Corporation (Jump Code: RL11S). An optical recognition line and a payment code will then be generated on the remittance slip. However, this information will not be generated if an amount appears on both lines 20.6 and/or 25.6 and line 50 of Form RL-11.S. A diagnostic will then remind you to complete a separate Form RL-11.S for Part 5, Special tax on expenses deemed to have been incurred in Québec.

Finally, please note that Revenu Québec prefers online payments using the invoice with the payment code.

TP-21.4.39, Cryptoasset Return (Jump Code: TP21439)

Form TP-21.4.39 is a mandatory reporting form for any partnership that, in a given fiscal period, owns, receives, disposes of (sells, transfers, trades, donates, etc.) or uses cryptoassets. The capital gains (or losses), business income (or losses) and property income (or losses) from cryptoassets must be reported by type of cryptoasset. The partnership may incur penalties if it does not meet the obligations set out in Form TP-21.4.39.

TP-1079.8.BE, Foreign Property Return (Jump Code: TP10798BE)

This form is equivalent to Form T1135 (Jump Code: T1135) for Québec.

The information entered in Form T1135 is reported into Form TP-1079.8.BE.

For more information, consult the Help.

Version 1.0 – Updated Forms

Federal

Permitted characters when transmitting slips

This year, the CRA has provided specific instructions relating to the characters that are permitted when transmitting slips. The T1120 diagnostic has been added to several cells in order to guide the user as to which characters are accepted when transmitting. This diagnostic will be displayed whenever an invalid character is entered. This character will then need to be corrected before the slip is transmitted in order to avoid any errors.

GST525, Supplement to the New Residential Rental Property Rebate Application – Co-op and Multiple Units (Jump Code: GST525)

Form GST525 has been updated to reflect the enhanced GST/HST rebate for new residential rental properties, increasing the rebate rate from 36% to 100% for purpose-built rental housing, with no phase-out threshold.

Also, the boxes 14%, under an agreement entered into before October 31, 2007 and 15%, under an agreement entered into before May 3, 2006 have been removed from this form.

If you completed this form using a previous version of the program, please select 14% or 15% rates, if applicable, before filing it.

Finally, with respect to the GST/HST rebate calculation in Part B, the total of all units should be entered manually on line G of section 3, Rebate totals for application Type 6 and Type 7, when box Rebate calculation for Type 6 – Purpose-built rental housing has been selected.

R102-R, Regulation 102 Waiver Application (Jump Code: R102R) and R105, Regulation 105 Waiver Application (Jump Code: R105)

The checkbox Check this box if it is related to the FIFA World Cup has been added to section I, Applicant identification. This checkbox indicates whether the Canadian individual tax number (ITN) relates to the FIFA World Cup.

RC199, Voluntary Disclosures Program (VDP) Application (Jump Code: RC199)

New changes to the Voluntary Disclosures Program came into effect on October 1, 2025. These changes aim to make the program more accessible to taxpayers and to allow them to correct unintentional errors or omissions more easily. Most sections have been simplified; therefore, if information had been entered in a previous version, it will need to be reviewed before completing this form.

Taxpayers and registrants who are contacted regarding a potential non-compliance issue are now eligible for the program.

Following the update, each applicant must complete a separate application in section 1. From now on, only one applicant’s information will be reported in section 1. In addition, fields have been added to section 2 to indicate the type of returns submitted by the taxpayer as part of the voluntary disclosure. Fields have also been added to section 2 to specify the type of income involved in the voluntary disclosure.

Finally, the taxpayer must indicate in section 3 whether the application will result in a tax amount owing and provide additional information related to the payment, if applicable.

Schedule 15, Beneficial Ownership Information of a Trust (Jump Code: T3SCH15)

The definition of a bare trust has been modified. As a result, bare trusts are not required to file a T3 return (Jump Code: T3RET) for years ending December 31, 2024, through December 30, 2025. The applicability of Schedule 15 has therefore been modified so that bare trusts that have a tax year-end before December 31, 2025, do not have to file Schedule 15.

T3, Trust Income Tax and Information Return (Jump Code: T3RET)

The T3 return has been updated to include line 925, Manitoba cultural industries printing tax credit, and line 926, Manitoba Rental Housing Construction Incentive Tax Credit.

These lines are input lines and are included in the electronic transmission of the T3 return.

T4/RL-1, Data Entry Screen – Employment Income (Jump Code: T4)

On the T4 slip, the wording of boxes 38, 39 and 41 has been changed to remove the mention before June 25, 2024, and the wording of boxes 90, 91 and 92 has been changed to remove the mention after June 24, 2024. This change ensures that the wording of the following boxes is identical: 38 and 90, 39 and 91, and 41 and 92. The CRA has confirmed that either set of boxes (i.e., 38, 39 and 41 or 90, 91 and 92) can be used to report security options benefits and deductions.

It should be noted that Revenu Québec has retained boxes L-9 and L-10, removing the mention before June 25, 2024, and has removed boxes L-11 to L-13 on the RL-1 slip.

T4PS/RL-25, Data Entry Screen – Payment from an EPSP (Jump Code: T4PS)

Several changes have been made to the T4PS and RL-25 slips:

  • Boxes B-2, Capital gains (or losses) realized before June 25, 2024, B-3, Capital gains (or losses) realized after June 24, 2024, C-3, Capital gains (or losses) realized before June 25, 2024, and C-4, Capital gains (or losses) realized after June 24, 2024, have been removed from the RL-25 slip.

T5/RL-3, Data Entry Screen – Investment Income (Jump Code: T5)

Several changes have been made to the T5 and RL-3 slips:

  • Box 34, Capital gains dividends – Period 1 – before June 25, 2024, has been removed from the T5 slip and can no longer be selected from the drop-down list in the Other information lines of the data entry screen.

  • In the instructions of the T5 slip, the wording of box 18 has been changed by removing the mention Period 1 – before June 25, 2024.

  • Boxes I-1, Dividends on capital gains realized before June 25, 2024, and I-2, Dividends on capital gains realized after June 24, 2024, have been removed from the RL-3 slip.

If you have completed T5 and RL-3 slips using a previous version of the program, we recommend that you review them before filing.

T1141, Information Return in Respect of Contributions to Non-Resident Trusts, Arrangements or Entities (Jump Code: T1141)

Form T1141 has been updated to allow for a joint election to be made so that a single person can file all T1141 returns on behalf of the others when multiple individuals are required to file them.

Boxes have been added to confirm that the information reported in sections A, B, C, and D is supported by supporting documents and to identify the supporting documents that are attached to the form. Questions have been added to page 2 of the form to obtain information about the administration of the trust, the arrangement or the non-resident entity.

T2057, Election on Disposition of Property by a Taxpayer to a Taxable Canadian Corporation (Jump Code: T2057)

The field 014 has been modified and can now contain a trust number or a business number, in addition to a social insurance number.

T5013/RL-15, Partnership Income (Jump Code: T5013)

The Excessive interest and financing expenses limitation (EIFEL) rules section has been added after the Share of partnership income or Loss (T5013/RL-15) section. It provides the member information needed to calculate the member's share of the partnership's interest and financing expenses or income.

Boxes 247 to 261 of the T5013 slip are now calculated using the specified proportion indicated in the EIFEL section of the T5013 slip and the amounts shown on Schedules 8, 12 and 130 of the T5013 return (Jump Codes: T5013S8, T5013S12 and T5013S130).

The clean hydrogen investment tax credit is a refundable tax credit that applies to eligible clean hydrogen property that is acquired and becomes available for use in respect of a qualified clean hydrogen project from March 28, 2023, to December 31, 2034. This credit is calculated and allocated to the partners of a partnership using Schedule 74 of the T5013 return. Schedule 74 can be found on the CRA’s website and will be available in a subsequent version of the program. In the meantime, boxes 294 to 297 relating to this credit have been added to Worksheet B of Form T5013 (Jump Code: T5013WSB) and Form T5013/RL-15 (Jump Code: T5013).

The clean technology manufacturing investment tax is a refundable tax credit that aims to encourage the investment of capital for clean technology manufacturing and processing as well as critical mineral extraction and processing in Canada from January 1, 2024, to December 31, 2034.

Schedule 76 can be found on the CRA’s website and will be available in a subsequent version of the program. In the meantime, boxes 292 and 293 relating to this credit have been added to Worksheet B of Form T5013 and Form T5013/RL-15.

Regarding the RL-15 slip (Jump Code: RL15SUPP), for any member of a partnership that is a trust, you must now provide its trust account number. This number must be indicated in the Partner’s identification section of Form T5013/RL-15. The information will then be carried over to the RL-15 slip as well as to Form TP-600 Schedule A (Jump Code: TP600SA), if applicable.

If a corporation that is a member of a partnership has elected to file its income tax return in a given functional currency, you must enter the code of the currency used in the Filing details section of Form T5013/RL-15 for that member. This information will then be carried over to box 202 in the additional information on the RL-15 slip.

If a partnership has earned business income (or losses), capital gains (or losses) or property income (or losses) from cryptoassets, it must allocate them to its members. Additional information codes 1-12, Net business income (or loss) from cryptoassets, 12-17, Capital gains (or losses) from cryptoassets, and 14-7, Gross business income from cryptoassets, have been created for this purpose and are available in Worksheet B of Form T5013 and Form T5013/RL-15. The information will then be carried over to the appropriate boxes in the additional information on the RL-15 slip.

Several changes have been made to the RL-15 slip to remove references to periods before June 25, 2024, and after June 24, 2024:

  • Boxes 11-5 to 11-7, 11-9, 12-10 to 12-16, 45-1 and 45-2 have been removed from the RL-15 slip.

  • The wording of boxes 11-1 to 11-4, 11-8 and 12-1 to 12-9 on the RL-15 slip has been modified.

RL-31 Slip, Information on the Occupancy of a Dwelling (Jump Code: RL31)

Box B, Number of tenants or subtenants who signed the lease for the dwelling, has been added to the Filing details section of the RL-31 slip data entry screen.

A new version of Form TP-600 is now available. This update introduces several adjustments aimed at improving the accuracy of returns and meeting new regulatory requirements.

Moreover, a checkbox has been added to report whether the partnership held specified foreign property with a total cost exceeding Can $100,000 at any time during its fiscal period, in cases where the fiscal period ends after December 30, 2025.

The form also features a new line for reporting income, gains and losses from Canadian and foreign sources related to cryptoassets. In addition, a field has been added to indicate the trust account number associated with the partners.

Lastly, the question regarding the holding or use of cryptoassets by the partnership during the fiscal period has been modified. The response format has changed from a checkbox to a Yes/No field. Please note that users who previously answered this question in an earlier version of the form will need to respond again, as the prior response will not be automatically rolled forward in this update.

TP-600 Schedule E, Summary of Certain Information to Enter on RL-15 Slips (Jump Code: TP600SE)

During the 2025–2026 budget speech, changes were announced regarding the tax credit relating to resources. These changes notably affect the codes that must be entered in box 73 of the RL-15 slip for expenses that may qualify for this credit.

Mandatory electronic filing (slips and RL slips)

The threshold for mandatory electronic filing of information returns for a calendar year has been lowered from 50 to 5 for information returns filed after January 1, 2025. For the latest information about the penalty for not filing information returns over the Internet, go to canada.ca/mandatory-electronic-filing.

Information return type reminder

As of January 2025, all returns included in a single submission must correspond to the same information return type. Accordingly, the T5013-FIN and T5013 information returns (slip and summary) must be filed separately.

Online validations by the CRA

Starting January 2026, additional validations will be performed by the CRA once the submissions have been sent. Any errors identified by the CRA during return and slip validations will be detailed in a Return Error Report.

The electronic filing portals will not accept XML files larger than 150 MB in compressed form or exceeding 1 GB when uncompressed.

Electronic transmission of slips to Revenu Québec

The maximum number of XML files that can be transmitted per transmitter number for a given taxation year is 3,599. If the preparer reaches the maximum number of files for a given year, he or she will need to request a new transmitter number. Therefore, it is preferable to group slips together into a single file rather than transmitting one slip per file.

Taxation years covered

Revenu Québec only accepts electronic transmissions of the RL slips for the 2025 and 2026 taxation years. Generally, the CRA does not impose restrictions about the taxation year that can be processed.

Important dates for Internet transmission

Cantax FormMaster 2025 complies with the latest Internet transmission requirements issued by government agencies. XML files generated with Cantax FormMaster 2025 can therefore be electronically transmitted:

  • To the CRA, starting on January 12, 2026;
  • To Revenu Québec, without any delay (as Revenu Québec’s Internet transmission service has been updated in November 2025).

The CRA has been offering electronic transmission for the T3 Trust Income Tax and Information Return, as well as the T3M, T3S and T3RCA returns using EFILE since March 2, 2022, and the T3P, T3D, T3GR, T3RI and T1061 returns since February 19, 2024. The CRA will close the transmission service on January 31, 2026, and will accept the electronic transmissions for the tax years 2025 and 2026 starting February 23, 2026.

Creation of the .XML file to transmit

Please note that it is not possible to include multiple files when creating the .XML file that is transmitted to tax authorities. Each .XML file created with Cantax FormMastercan include only one file (one T slip or RL slip issuer).

CRA’s Web Access Code

If you already have a Web access code, you can use it to file your information returns for 2025 and subsequent years.
