Keep More Wealth Within Your Family
In Canada's progressive tax system, the more you earn, the higher your marginal tax rate becomes. For a family with a single high-income earner, this can result in a significantly higher overall tax bill than a family where two spouses earn a moderate income. This is where income splitting comes in.
Income splitting is a set of strategies designed to shift income from a high-income family member to a lower-income family member, taking advantage of their lower marginal tax rates. For an incorporated professional, these strategies can lead to substantial tax savings for the family unit as a whole. However, the Canadian tax landscape for income splitting is complex, particularly with the Tax on Split Income (TOSI) rules.
One of the most straightforward income splitting strategies is to pay a reasonable salary to a spouse or adult child for legitimate work they perform for your professional corporation. This could include administrative tasks, bookkeeping, marketing, or any other role that contributes to the business.
By paying a salary, you create a tax-deductible expense for your corporation, and the income is taxed in the hands of the family member at their lower rate. This also allows them to build their own RRSP contribution room and CPP benefits.
A prescribed rate loan is a powerful tool that allows you to split investment income with a spouse or family member. This strategy is particularly effective when the CRA's prescribed interest rate is low.
This effectively transfers the future tax liability on investment growth to the lower-income spouse, reducing the family's overall tax bill. The interest on the loan must be paid by January 31st of the following year for the strategy to remain valid.
A family trust is a more complex legal structure, but it offers significant flexibility for income splitting and asset protection. Assets are transferred to a trust, managed by a trustee for the benefit of a group of beneficiaries (your family members).
Family trusts are particularly useful for holding shares of a professional corporation or other income-producing assets. They require careful setup and ongoing administration with the help of legal and tax professionals.
The TOSI rules were introduced to limit the ability of business owners to split income with family members who are not actively involved in the business. If TOSI applies, the split income is taxed at the highest marginal rate, negating the benefit of the strategy.
However, there are several important exclusions from the TOSI rules, including:
Successfully navigating the TOSI rules is critical to any income splitting strategy. It requires meticulous record-keeping and a clear understanding of the exemptions. Consider integrating these strategies with your estate planning for maximum impact.
Income splitting is not a DIY project. It requires a coordinated approach that integrates legal structures, corporate tax planning, and personal finance. When implemented correctly, these strategies can save your family tens of thousands of dollars in tax each year.
