Understanding Canadian tax incentives for commercial solar and battery storage

Investing in commercial solar energy and battery storage may offer more than long-term electricity savings.

Eligible Canadian businesses can potentially access federal tax incentives designed to encourage investment in clean energy infrastructure.

Two particularly important incentives are:

1. The Clean Technology Investment Tax Credit (ITC).
2. Accelerated Capital Cost Allowance (CCA) for qualifying clean-energy equipment.

Together, these incentives can improve the financial attractiveness of eligible projects. However, they operate differently and should be reviewed with a qualified tax professional.

1. What is the Clean Technology Investment Tax Credit?

The federal Clean Technology ITC is a refundable investment tax credit available to eligible taxpayers that acquire and put qualifying clean-technology property into use in Canada.

For eligible property acquired and available for use from March 28, 2023, through December 31, 2033, the credit can be up to 30% of eligible capital cost, provided the applicable requirements are met.

For eligible property acquired and available for use during 2034, the maximum regular rate decreases to 15%.

The program is scheduled to end after 2034.

What equipment may qualify?

Subject to applicable technical and tax rules, eligible equipment can include:

• Solar photovoltaic electricity generation equipment.
• Certain qualifying stationary battery energy storage equipment.
• Other specified clean-energy generation, heating and conservation equipment.

Not every component, installation expense or associated building improvement necessarily qualifies.

2. Who can claim the credit?

The Clean Technology ITC is primarily available to eligible taxable Canadian corporations and qualifying real estate investment trusts.

Certain qualifying taxpayers participating through partnerships may also claim their allocated share of the credit.

Eligibility depends on who owns the equipment, how it is used, when it is acquired and placed into service, and whether the taxpayer satisfies the applicable rules.

A business operated as a sole proprietorship, for example, should not automatically assume that the same credit is available as it would be to a qualifying corporation.

3. Example: A $200,000 commercial solar investment

Consider a hypothetical business purchasing a commercial solar system.

In this simplified example, the business could potentially qualify for a $60,000 refundable investment tax credit.

However, the amount ultimately claimed may differ because of eligibility restrictions, government assistance, labour requirements and the treatment of individual project costs.

The ITC is claimed through the eligible taxpayer's tax filing process. It is not an automatic point-of-sale rebate or an amount immediately deducted from the contractor's invoice.

4. Labour requirements are important

To qualify for the regular 30% credit rate, claimants generally must elect to satisfy applicable prevailing-wage and apprenticeship requirements, unless an exemption applies.

A claimant that does not elect to meet these requirements generally receives a rate reduced by 10 percentage points.

For example, an otherwise eligible project during the current full-rate period could receive a 20% rate rather than 30%.

For commercial projects, these requirements should be reviewed before installation contracts are finalized and work begins.

5. What is Accelerated Capital Cost Allowance?

Capital Cost Allowance, or CCA, allows businesses to deduct the cost of eligible depreciable assets for income tax purposes.

Qualified clean-energy generation and energy conservation equipment is generally associated with Class 43.1, which normally has a 30% declining-balance depreciation rate.

For qualifying Class 43.1 property acquired on or after January 1, 2025, and available for use before 2030, Canada's reinstated immediate-expensing rules can allow an enhanced first-year deduction of up to 100% of eligible depreciable cost, subject to applicable restrictions.

These enhanced rules are scheduled to phase out for qualifying equipment brought into use from 2030 through 2033.

What does this mean for a business?

A faster tax deduction can potentially reduce taxable business income sooner, improving the timing of tax savings.

Unlike a refundable investment tax credit, depreciation is not a cash rebate.

For example, a $100,000 eligible tax deduction does not mean the government pays the business $100,000. Its value depends on the applicable tax position, income, and other tax rules.

6. Can a business benefit from both the ITC and depreciation?

Potentially, yes.

Qualifying clean-energy property may be eligible for both the Clean Technology ITC and accelerated depreciation.

However, the benefits cannot simply be added together as though they were two independent cash rebates.

Investment tax credits can affect the property's depreciable tax basis or income inclusion, and other rules may limit deductions.

Government assistance, financing arrangements, leasing structures and other claimed tax credits can also change the calculation.

Businesses should have their accountant model the combined tax treatment before relying on a projected after-tax return.

7. Key considerations before proceeding

Before investing, a business should confirm:

• The legal entity that will own the equipment.
• Whether the equipment meets the relevant eligibility definitions.
• The eligible capital cost and any excluded expenses.
• Whether prevailing-wage and apprenticeship requirements apply.
• Whether other incentives reduce the ITC calculation base.
• When the equipment is expected to become available for use.
• Whether tax-credit recapture rules could apply if the equipment is sold, exported or converted to an ineligible use.

For qualifying Clean Technology ITC property, certain changes in ownership or use during the relevant ten-year period may trigger recapture of a previously claimed credit.

8. How Stellr Solar supports commercial customers

Stellr Solar can provide detailed equipment specifications, project quotations, system designs, installation documentation and commissioning information that may be useful to a business and its accountant when evaluating incentives.

Tax-credit eligibility, depreciation treatment and tax filings remain the responsibility of the taxpayer and its professional tax advisors.

Commercial solar is an investment in long-term energy infrastructure. Understanding the applicable tax incentives can help your business evaluate that investment more effectively.
