If your corporation received the Canada Carbon Rebate for Small Businesses, you may have wondered whether that money should have been reported as taxable income. The answer is now settled. According to the Canada Revenue Agency’s (CRA) Businesses – Tax information newsletter of May 21, 2026, the rebate is non-taxable for all fuel charge years. The newsletter also outlines what the CRA is doing about corporate returns that may have included the rebate in taxable income, and when business owners need to take action themselves.
What Changed: The Rebate Is Now Non-Taxable
The CRA newsletter confirms that on March 26, 2026, the Government of Canada passed legislation making the Canada Carbon Rebate for Small Businesses non-taxable for all fuel charge years. This is passed legislation, not a proposal.
The update follows a government commitment made earlier. On June 30, 2025, the government announced that it would make the rebate tax-free. That date matters, because the CRA uses it to separate corporations into different groups when deciding how to correct returns.
The CRA Is Reviewing T2 Corporation Income Tax Returns
Because some corporations may have reported the rebate as income, the CRA states that it is now reviewing T2 Corporation Income Tax Returns for businesses that may have included the rebate in taxable income for the year it was received. What happens next depends mainly on when your corporation filed its return.
Scenario 1: You filed before June 30, 2025, and the rebate is clearly shown
If your corporation filed before the June 30, 2025 announcement and there is a clear indication that the rebate amount was reported at line 295 of Schedule 1, the CRA says it will make an adjustment to remove the amount from the calculation of your taxable income. In this case, the CRA states that no action is required on your part.
Scenario 2: You filed before June 30, 2025, but it is unclear how the rebate was reported
If your corporation filed before the announcement and there is no clear indication that the rebate was included in taxable income, the CRA will request additional information to determine whether an adjustment to your T2 return is needed. If you receive such a request, respond promptly and accurately so the CRA can complete its review.
Scenario 3: You filed after June 30, 2025, and included the rebate in taxable income
This is the scenario where business owners must act. If your corporation filed after June 30, 2025, and included the rebate in taxable income, you will need to submit an adjustment request yourself. The CRA directs corporations to its guidance on requesting a reassessment of your T2 return. The CRA does not describe an automatic correction for this group, so waiting for the CRA to fix the return may not be enough.
The CRA also provides a flowchart on the tax treatment of the rebate that visually sets out this process.
A Simple Example
Consider two hypothetical corporations. Corporation A filed its T2 return in early 2025 and reported the rebate at line 295 of Schedule 1. Under the CRA’s guidance, the CRA would remove the amount from taxable income without the owner needing to do anything. Corporation B filed its T2 return in the fall of 2025 and included the rebate in taxable income. Corporation B would need to submit a request for reassessment to have the amount removed. These are illustrations only; actual treatment depends on your filing history.
Practical Steps for Business Owners
A short review now can prevent surprises later:
- Confirm whether your corporation received the rebate. Check your bank records and CRA correspondence to identify the amount and the year it was received.
- Find the filing date of the relevant T2 return. Whether it was filed before or after June 30, 2025 determines which scenario applies.
- Review how the rebate was reported. Determine whether the amount was included in taxable income and, for returns filed before the announcement, whether it was shown at line 295 of Schedule 1.
- Submit a reassessment request if required. If you filed after June 30, 2025 and included the rebate in taxable income, follow the CRA’s process for requesting a reassessment of your T2 return.
- Watch for CRA requests for information. Keep supporting records organized so you can respond quickly if the CRA asks for more details.
Make Sure You Don’t Miss CRA Correspondence
The same newsletter reminds businesses that the CRA now sends most business correspondence online. To make sure you receive notices, such as a request for additional information about your rebate, the CRA encourages businesses to sign in to My Business Account and add or update their email address. With a current email address on file, the CRA can let you know when new mail is available or when changes are made to your account.
Why This Update Matters
Reporting a non-taxable amount as income can mean your corporation paid more tax than necessary. Whether you need to act depends on your situation. For full details, review the CRA’s May 21, 2026 Businesses – Tax information newsletter and the related guidance linked in it.
