For incorporated businesses, particularly small to medium-sized enterprises (SMEs) in Ontario, understanding income splitting is essential to maximizing wealth, protecting family finances, and staying compliant with CRA regulations.

What is Income Splitting?

Income splitting, sometimes referred to as family income splitting, is a tax planning strategy that allows business owners and incorporated professionals to allocate income earned by their business or themselves among family members in order to take advantage of lower marginal tax rates. The primary goal of income splitting is to reduce the overall tax burden on a household in a legal and compliant manner.

For incorporated businesses, income splitting can take several forms, including paying dividends or salaries to spouses, adult children, or other family members who are shareholders or actively involved in the business. Another common approach involves setting up family trusts, which provide flexibility in distributing income to beneficiaries in the most tax-efficient way. Beyond dividends, salaries, and trusts, there are other legal mechanisms that can be used to shift income from higher-taxed individuals to family members in lower tax brackets, allowing families to optimize their combined tax position. Properly implemented, income splitting not only reduces taxes but can also support retirement planning, facilitate succession and wealth transfer strategies, and help family members build long-term financial security. It is a vital tool for incorporated business owners who want to maximize after-tax income while remaining fully compliant with CRA rules.

Why Income Splitting Matters for Incorporated Businesses

Reducing Overall Tax Burden

By distributing income to family members in lower tax brackets, business owners can minimize the overall household tax rate, keeping more money in the family.

Enhancing Retirement Planning

Income splitting supports retirement planning by enabling family members to contribute to RRSPs or pension plans, allowing tax-deferred growth and building long-term savings.

Succession Planning and Wealth Transfer

Combining income splitting with family trusts or dividend strategies can simplify transferring wealth to the next generation while minimizing tax consequences.

Paying Dividends to Family Members

How It Works
Issuing dividends to family members who are shareholders can shift income to those in lower tax brackets. Structuring share classes carefully ensures the most tax-efficient distribution.

Tax on Split Income (TOSI) Considerations
The CRA’s TOSI rules, introduced in 2018, limit income splitting for adult family members not actively involved in the business. Understanding TOSI is critical to avoid penalties.

Example Scenario
A business owner earning $200,000 annually issues dividends to a spouse with little other income. If allowed under TOSI rules, this can save thousands in taxes.

Paying Salaries to Family Members

Legally Permissible Employment
Family members can be employed and paid reasonable salaries, provided they perform actual work for the business.

Advantages
Salaries are deductible for the corporation, reducing corporate taxes. They also allow family members to contribute to RRSPs, building future retirement savings.

Using Family Trusts

What is a Family Trust?
A family trust lets business owners allocate income among multiple beneficiaries, distributing profits in a tax-efficient manner.

Benefits of Family Trusts

  • Flexible income allocation
  • Supports estate planning and wealth transfer
  • Protects assets from creditors

Compliance Considerations
Proper setup and management are essential to comply with CRA rules, so professional guidance is strongly recommended.

Incorporating Lifetime Capital Gains Exemption

Eligible Small Business Shares (ESBS)
Splitting ownership of qualifying small business shares among family members can allow multiple beneficiaries to access the lifetime capital gains exemption, maximizing tax savings during business sale or succession.

Income Splitting Through Retirement Contributions

Pension Plans for Family Members
Contributing to a pension plan or RRSP for family members who are employees reduces corporate taxable income while building retirement savings for the household.

Practical Tips for Implementing Income Splitting

Successfully implementing income splitting strategies requires careful planning, meticulous execution, and ongoing attention to detail. Here are essential guidelines to help you navigate this complex area of tax planning while staying compliant with CRA requirements.

Maintain Accurate Documentation
Comprehensive record-keeping forms the foundation of any successful income splitting strategy. The CRA scrutinizes these arrangements closely, particularly during audits, making proper documentation your first line of defense.

Review Regularly
Tax laws and TOSI rules change over time. Tax legislation evolves continuously, and what worked yesterday may not be compliant today. The Tax on Split Income (TOSI) rules have undergone significant changes in recent years, making regular strategy reviews more critical than ever.

Seek Professional Guidance
Income splitting involves intricate tax rules with severe penalties for non-compliance. The complexity of TOSI legislation, combined with the high stakes involved, makes professional guidance not just advisable but essential.

Common Mistakes to Avoid

  • Ignoring TOSI rules, leading to unexpected taxes
  • Paying salaries that exceed the actual work performed
  • Failing to document distributions properly
  • Not reviewing strategies regularly as laws evolve
