DT Max T2

  1. Version highlights

    1. Increase of the ceiling for CCA for Class 10.1 passenger vehicles

      Following the government announcement on January 14, 2026, the ceiling for CCA for Class 10.1 passenger vehicles will increase from $38,000 to $39,000 effective as of January 1, 2026.

      These changes have been implemented on federal Schedule 8, AT1 Schedule 13 and Quebec Form CO-130.A.

    2. CO-1029.8.33.13 - Message from Revenu Québec regarding line 28e

      As instructed by Revenu Québec, a revision in the calculation has been made to line 28e, Tips and indemnities that do not exceed the maximum pensionable earnings. Line 28e should now be solely coming from line 27 of the form. Since this change has been made in this DT Max T2 version, the option "Tips/indemn. not exceeding max. pensionable earnings" for the keyword Tip-Info within the Tips group that was used to set line 28e has now been deleted. Please verify your data entry.

      We have also been informed that a revised version of the CO-1029.8.33.13 will be released at the end of 2026. This version will indicate that line 27 must be carried over to line 28e.

  2. Known issue: new measures included in Bill C-15 relating to CCA

    As per our latest FAQ that pertained to the T2 program, the CRA will administer the measures mentioned below:

    • Reinstatement of the Accelerated Investment Incentive (AII) - provides an enhanced first-year write-off for most capital assets.

    • Immediate Expensing of clean energy generation and energy conservation equipment, as well as zero-emission vehicles.

    • Immediate Expensing of capital expenditures for scientific research and experimental development.

    • Immediate Expensing of productivity-enhancing assets, including patents, data network infrastructure, and computers.

    • Immediate Expensing (100% first-year write-off) of manufacturing or processing machinery and equipment.

    Currently, DT Max does not include the above changes.

    We have been notified by the CRA that Schedule 8 should be updated in late Spring 2026. However, they will administer the measures mentioned above.

    In the meantime, you will need to override the amounts in DT Max to claim the correct CCA amount. For the AII claim, the FactorOV keyword within the CCA-Class keyword group may be used to override the relevant factor currently being used in the calculation for Column 18 of Schedule 8. The keyword CCAClassOV keyword within the CCA-Class keyword group may also be used to override the AII claim or the immediate expensing claim for Column 23 of Schedule 8.

    Please note that the CRA will not administer the following measures until legislation is introduced:

    • Immediate Expensing for manufacturing or processing buildings.

    • Reinstatement of accelerated CCA for liquefied natural gas (LNG) equipment and related buildings, limited to low-carbon LNG facilities.
