M&A tax due diligence in Canada is the process of reviewing a target company’s tax compliance history and exposure before a transaction closes. It’s easy to assume that if a company’s financial statements look clean, its tax position is fine too, but tax liabilities don’t always show up clearly on a balance sheet. A thorough tax review often uncovers issues that directly affect deal terms, sometimes significantly.
What Tax Due Diligence Actually Involves
Tax due diligence generally means reviewing a target’s corporate income tax filings and history, sales and value-added tax compliance (GST/HST in Canada), payroll and source deduction remittances, and any outstanding CRA reassessments, audits, or disputes. The goal is to build a clear picture of the target’s actual tax position, not just what’s reflected in its financial statements.
Why Share Purchases Require Deeper Tax Due Diligence
The depth of tax due diligence required often depends on how the deal is structured. In a share purchase, the buyer generally takes on the entire corporation, including its full tax history and any liabilities, known or hidden, that come with it. In an asset purchase, the buyer typically assumes only the specific assets and liabilities negotiated as part of the deal, which can limit exposure to the target’s broader tax history. This difference is a major reason share deals tend to require a more thorough tax review than asset deals.
How Findings Can Reshape the Deal
What a tax due diligence review turns up doesn’t just inform the buyer; it often directly affects the deal itself. Issues uncovered during the process can lead to purchase price adjustments, escrow holdbacks to cover potential liabilities, or specific indemnification clauses protecting the buyer if a tax issue surfaces after closing. Tax-related purchase price adjustments show up in a meaningful share of mid-market M&A transactions, reflecting how often these reviews uncover something worth negotiating.
Tax Attributes That Can Be at Risk
Beyond identifying liabilities, tax due diligence also looks at the target’s tax attributes, such as non-capital loss carryforwards, which can be restricted or lost when control of a corporation changes hands. Whether and how this applies depends on the transaction structure and the target’s tax history, and it’s an area where professional advice before closing matters, since attributes lost through a poorly structured deal generally can’t be recovered afterward.
Why Tax Due Diligence Matters Even When the Deal Looks Clean
A target company can look financially healthy and still carry tax exposure that isn’t obvious from the outside, such as an unresolved CRA audit, a misclassified expense, or remittance issues that haven’t been flagged yet. These issues often don’t surface until a detailed review, which is why skipping or rushing tax due diligence is a common source of post-closing disputes.
Bringing in the Right Advisors Early
Tax due diligence works best when it starts early in the deal process, not as a late-stage formality. Bringing in tax advisors before terms are finalized gives both sides time to address what’s found, whether that means adjusting price, restructuring the deal, or simply entering the transaction with clear eyes about what’s being bought or sold.

FAQs
What’s the difference between tax due diligence in a share purchase versus an asset purchase?
Share purchases generally require a broader tax review, since the buyer takes on the corporation’s full tax history and liabilities. Asset purchases typically involve a narrower review, focused on the specific assets and liabilities being assumed.
Can tax due diligence findings change the purchase price?
Yes, this is common. Issues identified during a tax review can lead to purchase price adjustments, escrow holdbacks, or indemnification clauses to address potential liabilities.
What happens to a company’s tax losses when it’s acquired?
Certain tax attributes, including non-capital loss carryforwards, can be restricted or lost when control of a corporation changes hands, depending on the transaction’s structure. Review this with a tax advisor before the deal closes.
