Who this is for
Canadian-controlled private corporations that received the Canada Carbon Rebate for Small Businesses for one or more fuel charge years. That includes trucking companies, restaurants, shops and other small corporations with employees.
What to check
-
Did the corporation receive the rebate? It was paid to eligible corporations based on employees and province. The bank deposit and the CRA notice show the amount and the fuel charge years.
-
Was it included as income on a T2? Before the law changed, many corporations reported it as taxable income because that was the rule at the time.
-
When was that T2 filed? Before June 30, 2025: the CRA says it will adjust automatically if the rebate was clearly reported. If it was not, the CRA will write to the corporation. After June 30, 2025: the corporation must request an adjustment through the normal T2 reassessment process.
-
Is a T2 still unfiled? Report the rebate as non-taxable. Do not include it in income.
-
Watch for the notice. An automatic adjustment arrives as a Notice of Reassessment. A letter asking for information needs a reply. Nothing arriving may mean a request is needed.
One thing many people do not realize
Whether the CRA fixes this for you depends on a date: June 30, 2025, when the government announced the rebate would be non-taxable. Returns filed before that date with the rebate clearly reported are being adjusted automatically. Returns filed after that date that still included the rebate as income are not; the corporation has to ask. Many small corporations with summer year ends fall on the wrong side of that line.
What to prepare
- The rebate amounts and the fuel charge years they covered
- The T2 returns for the years in which the rebate was reported, with filing dates
- Any CRA letter or reassessment received about it
When professional help may make sense
The rebate reported across more than one year. A year end that straddles the June 30, 2025 date. A reassessment request. In each case the adjustment should be prepared carefully so it does not reopen other items.
