GAAR Explained: What Tax Transactions the CRA Considers Avoidance

Section 245 of the Income Tax Act — the General Anti-Avoidance Rule (GAAR) — is one of the most powerful tools in CRA's arsenal. It allows CRA to deny tax benefits that arise from transactions that technically comply with the letter of the law but that abuse or misuse the purpose behind it. For Calgary incorporated businesses undertaking corporate reorganizations, estate freezes, or surplus stripping strategies, GAAR exposure is a real risk that must be assessed before implementation. GAAR was significantly strengthened in 2024 — including a new 25% penalty — making it more important than ever to understand where legitimate planning ends and avoidance begins. GAAR assessments are conducted through the expanded powers described in our guide to the CRA audit process in Canada.

1. The Three-Part GAAR Test

For GAAR to apply, CRA must establish three elements:

1. There is a tax benefit — a reduction, avoidance, or deferral of tax that would not otherwise arise
2. There is an avoidance transaction — a transaction that is primarily motivated by obtaining a tax benefit (rather than a bona fide non-tax purpose)
3. The transaction is abusive — it abuses the provisions of the Act read in light of their object and spirit, or the tax treaty applied

All three must be present. A transaction with legitimate business purpose is not caught by GAAR even if it produces a tax benefit. And a transaction motivated by avoiding tax is not caught if it does not abuse the purpose of the provisions it relies on.

2. What Makes a Transaction "Abusive"?

The abuse test is the most contested element. Courts have held that a transaction is abusive when it produces a result that is inconsistent with the purpose of the provision that provides the benefit — when the taxpayer relies on technical compliance while defeating the legislative intent.

Examples of transactions found abusive by courts include: using stop-loss rules to create artificial losses through related-party transactions; manipulating the surplus accounts of a corporation before an acquisition to strip gains tax-free; and structuring share redemptions to convert dividends into capital gains to take advantage of the lower inclusion rate where the provisions were not designed to permit such a conversion.

3. Economic Substance and the 2024 Test

The 2024 amendments codified an economic substance framework into GAAR. Where a transaction lacks economic substance — meaning there is no genuine commercial impact, no real change in economic position, or the steps are circular — this is now explicitly relevant to the abuse analysis.

CRA can weigh factors including:

• Whether the transaction changes the taxpayer's economic position in a meaningful way
• Whether there are business reasons independent of tax motivating the transaction
• Whether the transaction involves offsetting positions that neutralize economic risk
• Whether the transaction mirrors or reverses itself in a way that leaves no genuine net economic change

4. The New 25% GAAR Penalty

Prior to 2024, GAAR carried no penalty — the consequence was merely denial of the tax benefit, plus interest. The 2024 amendments added a 25% penalty on the tax benefit arising from an abusive avoidance transaction. On a $200,000 tax benefit, that penalty alone is $50,000 — on top of the denied benefit and compounding interest. This penalty can only be avoided if the taxpayer demonstrates the transaction was not primarily motivated by the tax benefit, or had reasonable grounds to believe GAAR would not apply.

GAAR Consequence	Pre-2024	Post-2024 (new transactions)
Tax benefit denied	Yes	Yes
Interest on denied benefit	Yes	Yes
GAAR penalty	No	25% of denied benefit
Extended limitation period	Normal	+3 years for GAAR assessments

5. What GAAR Does Not Reach

Not every tax-motivated transaction triggers GAAR. The Income Tax Act is full of provisions specifically designed to provide tax benefits — RRSP deductions, capital gains exemptions, dividend tax credits, incorporation savings — and using these provisions as intended is not avoidance. GAAR is specifically targeted at transactions that exploit technical provisions in a manner Parliament did not intend. Properly structured transactions with genuine business purpose generally do not attract GAAR risk. Calgary business owners who undertake corporate tax planning using standard mechanisms — the small business deduction, LCGE planning, section 85 rollovers — are typically well within the bounds of legitimate planning.

6. Working with Swift Accounting on GAAR Risk Assessment

Any complex tax planning transaction — corporate reorganizations, estate freezes, surplus stripping strategies, income splitting arrangements — should be reviewed for GAAR risk before implementation. For a deeper analysis of where the line sits between legitimate planning and avoidance, see our companion guide on GAAR and the limits of tax avoidance in Canada. Our tax professionals assess proposed transactions for GAAR exposure and work with tax lawyers on opinions for high-stakes planning. Contact us before implementing any strategy that relies on technical provisions in a non-obvious way — the 2024 penalty regime makes pre-implementation review essential.
