Issuing Shares to Family Members: Tax Rules to Avoid Attribution and TOSI — CPA Firm Near You, Montreal

Introduction
Many Quebec business owners want to issue shares to spouses or adult children to reduce taxes, transfer wealth, or prepare for future succession. But issuing shares to family members is heavily regulated under Canada’s Tax on Split Income (TOSI) rules and attribution rules. A poorly structured share issuance can trigger punitive tax rates, denied deductions, capital gains attribution, or reassessments. This guide explains how to issue shares to family members properly, how TOSI applies, and how a CPA near you in Montreal can help structure the plan correctly.
Legal and Regulatory Framework
Under the Income Tax Act, shares issued to family members must comply with attribution rules and TOSI. Attribution rules prevent shifting income to spouses or minor children by automatically reassigning taxable income back to the original taxpayer. TOSI applies punitive tax rates to dividends received by certain family members unless they qualify for an exemption such as excluded shares, excluded business, labour contribution, capital contribution, or age-based exemptions (spouses of owners 65+). Corporate law under the QBCA or CBCA requires that any issuance of shares be documented with resolutions, updated share registers, amended articles (if new share classes are required), and proper minute book entries.
Key Court Decisions
Courts have ruled that dividends paid to family members through artificial structures are subject to TOSI. Judges confirmed that family members must either contribute labour, invest capital, or hold excluded shares to avoid punitive taxation. Several decisions denied tax benefits where share issuances lacked proper documentation, where valuations were inaccurate, or where structures lacked economic substance. Courts emphasize that issuing shares to minors or non-active spouses often triggers attribution or TOSI unless exceptions are satisfied.
Why CRA and Revenu Québec Scrutinize Family Share Issuances
Issuing shares to family members is a known tax planning technique. CRA looks for whether family members contributed to the business, whether shares qualify as excluded shares under TOSI, whether dividends match labour or capital contributions, whether valuation was performed correctly, and whether the issuance was properly documented. Revenu Québec examines minute books, share registers, and resolutions for legal compliance. Improper structures raise audit risk and can lead to reassessments.
How to Issue Shares to Family Members Without Triggering Attribution or TOSI
Use excluded business rules
Family members who work an average of 20 hours per week in the business can receive dividends free from TOSI.
Use excluded shares rules
Shares that are not professional corporations and where the family member owns at least 10% of votes and value may qualify.
Use age 65+ exception
Dividends paid to a spouse of an owner aged 65+ may bypass TOSI.
Rely on capital contributions
Family members who invest capital at fair market value may receive dividends without attribution.
Use a family trust
A trust can hold shares and allocate income strategically, but TOSI must still be considered.
Consider growth shares
New common shares with nominal value can be used for long-term planning without shifting existing value.
Critical Documentation Steps
Corporate resolutions
The board must approve issuing shares and document the details.
Updated share registers
Registers must show issuance date, number of shares, and shareholder information.
Share certificates
Physical or digital certificates must be issued.
Fair market value valuation
The corporation must justify the value assigned to shares issued.
Minute book updates
All records must be stored and updated for legal compliance.
Common Pitfalls
Issuing shares at undervalued prices
This creates shareholder benefits or deemed dividends.
Paying dividends to inactive family members
This triggers TOSI and punitive tax rates.
Ignoring attribution rules for minors
Income may be reassigned back to the parent.
Missing documentation
CRA and RQ may deny tax positions or reverse transactions.
Failing to create proper share classes
Non-voting or preferred shares may be needed to structure allocations correctly.

Common Questions
Can I issue shares to my spouse to split income?
Yes, but only when TOSI exemptions apply.
Are dividends to adult children always subject to TOSI?
Not if they work in the business, own excluded shares, or invest capital.
What if I issue shares to minors?
Attribution rules will generally apply, making income taxable to you.
Do I need a valuation?
Yes, if shares have value or if a freeze is involved.
