Tax Incentives for Clean Energy Technologies described in Class 43.1 and 43.2

Accelerated Capital Cost Allowance for Specified Clean Energy and Energy Conservation Equipment and Canadian Renewable and Conservation Expenses

Businesses can take advantage of important tax incentives under the Income Tax Act, that encourage investments in clean energy generation and energy conservation projects. Specifically, this website provides guidance on the accelerated capital cost allowance provided under Classes 43.1 and 43.2, and Canadian Renewable and Conservation Expenses, though other tax incentives may also be available to businesses that make these investments.

Note: Some of the technologies described in Class 43.1 and 43.2 may be eligible for the refundable Clean Technology Investment Tax Credit of up to 30% of the capital cost of specified clean technology property.  For more information, please see website linked below:

Canada Revenue Agency’s new Clean Technology Investment Tax Credit

Under Classes 43.1 and 43.2 in Schedule II of the Income Tax Regulations, certain capital costs of systems that produce energy by using renewable energy sources or fuels from waste, that conserve energy by using fuel more efficiently, or that produce low-carbon fuels from waste are eligible for an accelerated capital cost allowance. Under Class 43.1, eligible equipment may be written off at 30 percent per year on a declining balance basis. In general, equipment that is eligible for Class 43.1 but is acquired after February 22, 2005, and before 2025 may be written off at 50 percent per year on a declining balance basis under Class 43.2. Without these accelerated write-offs, many of these assets would be depreciated for income tax purposes at lower annual rates.

Note that, as announced in the 2018 Fall Economic Statement, there is an enhanced first-year allowance for property currently included in Class 43.1 or 43.2, if it is acquired after November 20, 2018, and becomes available for use before 2028. The enhanced first-year allowance provides a 100 percent deduction, with a phase-out for property that becomes available for use after 2023.

In addition to Class 43.1 or 43.2 accelerated capital cost allowance, the Income Tax Regulations allow certain expenses incurred during the development and start-up of renewable energy and energy conservation projects [Canadian renewable and conservation expenses (CRCE)] to be fully deducted in the year they are incurred, carried forward indefinitely and deducted in future years, or transferred to investors under a flow-through share agreement.

To qualify as CRCE, expenses must be incurred in respect of a project for which it is reasonable to expect at least 50 percent of the capital costs incurred for the project would be the capital costs of equipment described in Class 43.1 or 43.2.
