How to Perform an Estate Freeze: Locking in Value and Passing Future Growth to Heirs — CPA Firm Near You, Montreal

Introduction
An estate freeze is one of the most powerful tax planning tools available to Quebec business owners and families with growing assets. It allows you to “lock in” the current value of your business or investments and pass future growth to the next generation, often through a holding company or family trust. Estate freezes reduce future tax liability, protect wealth, and create a clear succession plan. This guide explains how an estate freeze works, why it matters, and how a CPA near you in Montreal can help implement it correctly.
Legal and Regulatory Framework
Under the Income Tax Act, an estate freeze typically involves exchanging the owner’s common shares for fixed-value preferred shares and issuing new common shares to heirs, a holding company, or a family trust. The preferred shares represent today’s locked-in value, while new common shares capture all future growth. Estate freezes must be documented with share exchange agreements, resolutions, corporate reorganizations, and updated minute books. Section 85 or 86 of the Income Tax Act is often used to roll assets into a new structure without triggering immediate tax. CRA requires fair market value assessments, proper share classes, and accurate documentation.
Key Court Decisions
Courts have ruled that estate freezes must reflect economic reality. Judges have denied freeze transactions where valuations were inaccurate, where documentation was incomplete, or where the freeze lacked commercial purpose. Some decisions confirmed that improperly implemented freezes triggered capital gains or shareholder benefit assessments. Courts emphasize that estate freezes must follow strict corporate and tax rules to be valid.
Why CRA and Revenu Québec Scrutinize Estate Freezes
Estate freezes involve subjective valuations, related-party transactions, complex reorganizations, and long-term tax deferral. CRA examines whether the freeze reflects fair market value, whether documentation supports the freeze, whether family trusts are used properly, whether beneficiaries are subject to Tax on Split Income (TOSI), and whether shares were issued correctly. Revenu Québec reviews share attributes, resolutions, and compliance with the QBCA/CBCA. Errors increase audit risk significantly.
What an Estate Freeze Achieves
Locks in today’s value
Your future taxable gain is capped at the time of the freeze.
Transfers future growth
Future appreciation is shifted to children, heirs, or a family trust.
Reduces estate tax
By capping growth, your tax burden on death is lower.
Facilitates business succession
Provides a clear plan for transferring ownership gradually.
Creates planning flexibility
Family trusts can allocate income or capital gains strategically.
Helps protect assets
Future assets grow outside your personal estate, reducing creditor exposure.
How to Perform an Estate Freeze: Step-by-Step
Step 1: Valuation
A CPA assesses the fair market value of the business or assets.
Step 2: Create or update share structure
Preferred shares are issued to the owner; new common shares go to heirs or a trust.
Step 3: Share exchange
The owner exchanges common shares for preferred shares, often using Section 85 or 86.
Step 4: Issue new growth shares
Family members or a trust receive common shares for future growth.
Step 5: Update corporate records
Minute books, share registers, and resolutions must document the freeze.
Step 6: Integrate a family trust (optional)
A trust allows flexible distribution of growth among multiple beneficiaries.
Step 7: Implement long-term tax planning
Managing dividends, shareholder loans, and passive income is critical after the freeze.
Common Pitfalls
Incorrect valuations
Understating or overstating value creates tax risk.
Missing documentation
Without proper records, CRA can reverse the freeze.
TOSI issues
Dividends or gains allocated to family members may be taxed at punitive rates.
Passive income problems
Holdings with excessive passive income may reduce the Small Business Deduction.
Improper use of preferred shares
Attributes must match tax rules to avoid reassessments.
