Leverage corporate structure to build wealth
For Canadian dentists, incorporating your practice is one of the most impactful financial decisions you will make. A Dentistry Professional Corporation (DPC) is not just a legal structure; it is a powerful vehicle for tax planning, liability protection, and long-term wealth accumulation. Understanding when and how to incorporate is fundamental to maximizing your financial success.
The decision to incorporate is unique to each dentist's financial situation, but a general guideline is to strongly consider it when your practice's net income consistently exceeds your personal lifestyle needs. This often occurs when your personal taxable income surpasses the $150,000 to $200,000 range.
At this point, you can leave surplus earnings in the corporation to be taxed at a much lower rate, rather than drawing all income personally and being taxed at the highest marginal rates. This tax deferral is the primary driver of wealth creation through a corporation.
Beyond tax deferral, a professional corporation provides liability protection by separating your personal assets from your business liabilities, and it may allow you to qualify for the Lifetime Capital Gains Exemption on the eventual sale of your practice, which can shelter a significant portion of the sale proceeds from tax.
A Canadian-controlled private corporation (CCPC) benefits from the small business deduction, resulting in a much lower corporate tax rate (approximately 12% in Ontario) on the first $500,000 of active business income, compared to personal tax rates that can exceed 53%. This leaves more after-tax dollars in the corporation to reinvest and grow.
A corporation is a separate legal entity, which creates a shield between your business liabilities and your personal assets. This is a critical component of creditor proofing, protecting your family's home and personal savings from risks associated with the practice.
Upon the sale of your practice, the shares of your corporation may qualify for the LCGE. This exemption allows for a significant portion of the capital gain to be realized tax-free, potentially saving you hundreds of thousands of dollars.
An incorporated practice provides flexibility in how you are compensated. You can pay yourself a salary, dividends, or a combination of both to optimize your personal tax situation. This flexibility is key to advanced tax planning strategies.
A corporation can establish an Individual Pension Plan (IPP), a powerful retirement savings tool that allows for significantly higher tax-deductible contributions than a traditional RRSP, especially for dentists over 40.
Properly structuring your corporation from the outset is crucial to maximizing its benefits. This often involves more than just the professional corporation itself.
A holding company can be established to own the shares of your professional corporation. This structure can provide an additional layer of creditor protection, facilitate the purification of the operating company to qualify for the LCGE, and allow for the tax-efficient flow of dividends. Many incorporated dentists also layer in corporate-owned life insurance to shelter surplus inside an exempt policy and ultimately distribute proceeds tax-free through the Capital Dividend Account.
A family trust can be used as a shareholder of the holding company, providing flexibility for income splitting among family members and for the tax-efficient transfer of wealth to the next generation.
NUANS name search, select share structure (common vs preferred shares for income splitting), appoint directors, designate registered office. Lawyer recommended for tax-optimal share structure.
Provincial registration ($300-$500), obtain corporate minute book, create shareholder agreements (if multiple owners), set up corporate bank account.
CRA business number, corporate income tax account, payroll account (RP), GST/HST account (if applicable over $30K revenue). Register with provincial licensing bodies.
Structure as asset or share purchase. Asset purchase: buy equipment, patient files, goodwill individually. Share purchase: buy seller's corporation shares (more complex, CRA clearance required).
While powerful, incorporation is not a one-size-fits-all solution. If you need to draw all of your practice income to cover your personal living expenses and debt repayments, the tax deferral advantage is nullified. The administrative costs and complexity of maintaining a corporation may also outweigh the benefits in the very early stages of a career.
