An estate freeze uses Section 85 of the Income Tax Act to transfer future corporate growth to heirs while deferring capital gains. If the CRA audits your freeze, missing promissory notes or incorrect Fair Market Value (FMV) calculations can unravel the entire reorganization, triggering massive, immediate tax liabilities. Always consult a Canadian tax lawyer to ensure compliance.
For Canadian business owners, passing a successful company down to the next generation without triggering a crippling tax bill is a primary goal. 💼 To achieve this, many utilize an “estate freeze” under Section 85 of the Income Tax Act. This legal maneuver allows the founder to “freeze” the current value of their shares, convert them into fixed-value preferred shares, and issue new common shares to their children or a family trust. This defers the capital gains tax until the founder passes away or sells the preferred shares.
Because estate freezes involve transferring immense wealth, the Canada Revenue Agency (CRA) scrutinizes these corporate reorganizations heavily. When conducting an audit, the CRA looks for missing documentation, particularly the exact valuation of the company and the presence of legal “promissory notes.” A promissory note acts as an official IOU when assets are transferred. If the CRA discovers flaws in these documents, they can invalidate the rollover, meaning you could be taxed immediately on the full value of the business.
Step-by-Step Process for Handling a Section 85 Audit
Facing an audit on a corporate reorganization is not a simple matter of sending in a few receipts. 📝 It requires a robust legal and accounting defence to prove that every step of the estate freeze complied strictly with Canadian tax laws.
Step 1: Engage a Canadian Tax Lawyer
Before you hand any documents over to the CRA, it is highly advisable to hire a Canadian tax lawyer rather than relying solely on your accountant. Tax lawyers provide “solicitor-client privilege,” meaning your strategic discussions are legally protected and cannot be forced out of you by the CRA. They will guide the entire audit defence strategy.
Step 2: Review the T2057 Election Form
The foundation of an estate freeze is the T2057 form (Election on Disposition of Property by a Taxpayer to a Taxable Canadian Corporation). 📄 Your legal team will verify that this form was filed on time and that the “Agreed Amounts” match the corporate ledgers. A late or improperly filled T2057 is a red flag for the CRA and must be addressed immediately.
Step 3: Validate the Fair Market Value (FMV)
The CRA will challenge the valuation of your business at the time of the freeze. If you froze the company at $2 million, but the CRA believes it was worth $5 million, they will attempt to tax you on the hidden $3 million benefit. You must provide the original, independent professional valuation report created at the time of the freeze to justify your numbers.
Step 4: Prove the Existence of Promissory Notes
During the asset transfer, “boot” (non-share consideration like cash or debt) is often issued in the form of a promissory note. 💷 The CRA will demand to see the physically signed promissory note. If the note was never drafted, or if the terms do not match the corporate resolutions, the CRA may recharacterize the transaction, triggering severe tax penalties.
Step 5: Rely on the Price Adjustment Clause
If the CRA successfully argues that your initial valuation was incorrect, your best defence is a properly drafted Price Adjustment Clause (PAC). This is a legal safety net built into your corporate articles. It legally states that if the CRA determines the Fair Market Value is different, the company will automatically adjust the redemption value of the preferred shares to match, thus avoiding the immediate penalty tax.
How Much Does it Cost in Canada?
Defending a complex corporate reorganization audit is a significant investment. 💲 Because millions of dollars in tax deferrals are on the line, professional fees reflect the high stakes involved. As of May 2026, standard costs include:
- Tax Law Firm Retainer: Hiring a specialized tax lawyer typically requires an upfront retainer of $5,000 to $15,000 CAD.
- Hourly Legal Fees: Senior tax lawyers and litigation experts in Canada charge between $450 and $900 CAD per hour.
- Chartered Business Valuator (CBV): If you need a retroactive valuation expert to argue against the CRA’s math, expect to pay $5,000 to $20,000 CAD for a comprehensive report.
How Long Does the Process Take?
Corporate tax audits move very slowly. ␐ From the moment you receive the initial CRA inquiry letter, gathering documents and corresponding with the auditor can take 6 to 12 months. If the auditor issues an unfavourable reassessment and you must file a Notice of Objection, the appeals process can easily drag on for one to three years before reaching a final resolution.
Frequently Asked Questions (FAQ)
What is a Section 85 rollover in Canada?
Section 85 of the Canadian Income Tax Act allows a taxpayer to transfer assets (like shares or real estate) into a Canadian corporation on a tax-deferred basis. It prevents the transfer from being treated as a typical sale, meaning no immediate capital gains tax is triggered.
Can the CRA tax a promissory note?
A promissory note represents debt, not income, so the note itself is not taxed. However, if the face value of the note exceeds the tax cost of the assets transferred, it will trigger an immediate capital gain that the CRA will tax.
What happens if my Price Adjustment Clause is ignored by the CRA?
The CRA generally respects a PAC if a legitimate, good-faith attempt was made to determine the Fair Market Value at the time of the freeze. If the CRA believes you deliberately undervalued the company to evade taxes, they can refuse to honor the PAC.
Does an estate freeze avoid tax forever?
No. An estate freeze only defers the tax liability. When the founder eventually passes away, there is a “deemed disposition” of their preferred shares, and their estate will have to pay the capital gains tax at that time.
