Canada Carbon Rebate for Small Businesses: What Businesses Need to Know  

The Government of Canada has made an important update to the Canada Carbon Rebate for Small Businesses, affecting both the tax treatment of the rebate and how previously filed corporate tax returns may be handled.

Below is a high-level overview of what’s changed and what business owners should be aware of.

​Key Update: Rebate Is Now Non-taxable 

As of March 26, 2026, legislation has been passed confirming that the Canada Carbon Rebate for Small Businesses is non-taxable for all fuel charge years.

What this means:

• The rebate does not need to be included in taxable income
• This applies retroactively to 2019-2020 through 2023-2024 fuel charge years, provided the required eligibility criteria are met
• Businesses that previously reported the rebate as taxable may see adjustments made by CRA

How CRA is Handling This

CRA is currently reviewing T2 Corporation Income Tax Returns where the rebate may have been reported as taxable income.

• If the rebate was clearly reported as taxable income (for example, at line 295 of Schedule 1), CRA will automatically adjust the return; no action required
• If it’s not clear whether the rebate was included in taxable income, CRA may contact the corporation to request additional information

Businesses should monitor CRA correspondence.

CRA expects most remaining retroactive payments to be issued by Fall 2026. For full details please refer to Canada Carbon Rebate for Small Businesses. If you have any questions, please contact your Stark & Marsh Advisor.
