There is no GIFI code to use for the carbon tax rebate on a T2 return, because the Canada Carbon Rebate for Small Businesses is non-taxable. Legislation passed on March 26, 2026, retroactively removed the rebate from taxable income for every fuel charge year, so it should not appear in your revenue figures and should not be assigned to an income-related GIFI code. Practitioners previously used GIFI 8242 or 8230, and if your accounting records still carry the rebate in one of those lines, the fix is to back it out before the GIFI data flows into your T2, or to deduct it on line 295 of Schedule 1.
Why No Income Code Applies Anymore
Before March 2026, the rebate fell under paragraph 12(1)(x) of the Income Tax Act, the general rule that requires corporations to include most government assistance in income. That paragraph covers grants, subsidies, forgivable loans, and similar payments received in the course of earning business income. Corporations recorded the rebate as revenue and reported it on their GIFI financial statements accordingly.
The March 26, 2026 legislation carved the Canada Carbon Rebate for Small Businesses out of that requirement. The change applies retroactively to every fuel charge year, not just future ones. A rebate received for any year from 2019‑2020 through 2024‑2025 is non-taxable.
The GIFI Codes Previously Used
The General Index of Financial Information is a standardized list of codes corporations use to report financial statement data alongside their T2 return. Every line on your balance sheet and income statement maps to a GIFI code so the CRA can process financial data consistently across industries and software packages.
Before the non-taxability legislation, two codes came up in practice:
- 8242 (Subsidies and grants), the more precise code, designated for federal, provincial, territorial, or municipal grants and government assistance payments.
- 8230 (Other revenue), a catch-all for gains on debt settlement and miscellaneous revenue, sometimes used when accounting software lacked a dedicated subsidy line.
Both roll up into GIFI 8299 (Total revenue). Some practitioners took a different approach and offset the rebate against fuel expenses using GIFI 9270 (other expenses on the short-form GIFI), but the CRA’s standard treatment was as a revenue item, not a cost reduction.
None of these codes is the right home for the rebate now. It is not revenue, and it is not an expense offset.
Backing the Rebate Out of Your GIFI Data
If your accounting software automatically posted the rebate to income when it hit the bank, you have two options. The cleaner one is to reverse the entry in your bookkeeping so the rebate never appears in the GIFI revenue that feeds your T2. Reclassify it out of 8242 or 8230 and record it as a non-taxable receipt.
If the rebate does end up flowing into your GIFI revenue totals, use line 295 of T2 Schedule 1, which reconciles accounting income to taxable income, to deduct the rebate amount. Schedule 1 exists for exactly this kind of book-to-tax adjustment: the accounting statements show one figure, and the return reports the taxable figure after adjustments.
If You Already Filed a Return That Included the Rebate
The path forward depends on when the return was filed.
Filed Before June 30, 2025
The CRA is reviewing these returns automatically. If the return shows the rebate amount at line 295 of Schedule 1, the CRA will adjust the return to remove that amount from taxable income without any action from you. If there is no clear indication the rebate was included, the CRA will contact you and request additional information before making any adjustment.
Filed After June 30, 2025
If you filed after the CRA’s initial announcement but still included the rebate in taxable income, submit an adjustment request yourself. You can do this through the Represent a Client portal or My Business Account by requesting a reassessment of the T2 return.
Records to Keep
Canadian tax law requires corporations to retain all records and supporting documents for six years from the end of the last tax year they relate to. This applies under the Income Tax Act, the Excise Tax Act, the Employment Insurance Act, and the Canada Pension Plan. For the carbon rebate specifically, keep the CRA notice or statement showing the payment amount, bank records confirming receipt, and any T2 schedules or working papers where the amount was recorded or adjusted. If the CRA reassesses a prior return to remove the rebate from income, keep that correspondence too.
Records can be stored electronically as long as they are readable by CRA software and contain enough detail to support the returns you filed. Records kept on servers outside Canada require CRA permission and must remain accessible to CRA officials in Canada in a readable electronic format. Information Circular IC05-1 sets out the detailed rules for electronic record keeping.
