Tax-Efficient Strategies for Withdrawing Retained Earnings from Your Dental Corporation

The foundational decision in withdrawing retained earnings is the choice between paying yourself a salary or declaring dividends. A salary is a deductible expense for your dental corporation, reducing its taxable income. Personally, a salary provides you with a predictable income stream, requires contributions to the Canada Pension Plan (CPP), and, crucially, generates Registered Retirement Savings Plan (RRSP) contribution room.

For many dentists, maximizing RRSP room is a cornerstone of their retirement planning strategy. Dividends, on the other hand, are paid out of the corporation's after-tax retained earnings. They do not generate RRSP room and do not require CPP contributions. Dividends are taxed personally at a different rate than salary, utilizing the dividend tax credit mechanism to account for the taxes already paid by the corporation.

The optimal mix of salary and dividends is highly individualized, depending on your personal cash flow needs, your desire to participate in CPP, and your overall tax planning framework. The Capital Dividend Account (CDA) One of the most powerful tools for tax-efficient wealth extraction is the Capital Dividend Account (CDA). The CDA is a notional account that tracks the tax-free portion of capital gains realized by your dental corporation.

When your corporation sells an investment (such as stocks, mutual funds, or real estate) at a profit, only a portion of that capital gain is taxable. The non-taxable portion is added to the CDA. You can then declare a capital dividend to yourself, which is received entirely tax-free personally. Monitoring and utilizing your CDA is essential for efficient corporate surplus management.

By strategically timing the realization of capital gains and the subsequent payment of capital dividends, you can significantly reduce the overall tax burden of withdrawing retained earnings. Individual Pension Plans (IPPs) For high-income dentists, an Individual Pension Plan (IPP) offers a robust alternative to traditional RRSPs for extracting retained earnings.

An IPP is a defined benefit pension plan established by your professional corporation, typically for yourself and potentially a spouse if they are employed by the practice. Contributions to an IPP are made by the corporation and are fully tax-deductible, effectively moving retained earnings out of the corporate tax environment and into a tax-sheltered pension environment. Furthermore, IPPs often allow for higher contribution limits than RRSPs, particularly for dentists over the age of 40.

This strategy not only secures your retirement income but also serves as a highly efficient method for withdrawing corporate surplus. Shareholder Loans In certain situations, you may need short-term access to corporate funds without immediately declaring a salary or dividend. A shareholder loan allows you to borrow money from your dental corporation. However, strict rules govern these loans.

To avoid the loan being included in your personal taxable income, it must generally be repaid within one year after the end of the corporation's taxation year in which the loan was made. If the loan is not repaid within this timeframe, the Canada Revenue Agency (CRA) will treat the entire amount as personal income, leading to a substantial tax bill.

Therefore, shareholder loans should be used cautiously and only as a temporary measure, not as a long-term strategy for withdrawing retained earnings.

Historically, dentists used their professional corporations to split income with family members in lower tax brackets by paying them dividends. However, the introduction of the Tax on Split Income (TOSI) rules has severely restricted this practice. Under TOSI, dividends paid to family members who are not actively engaged in the dental practice on a regular, continuous, and substantial basis are taxed at the highest marginal personal tax rate.

While income splitting via dividends is now much more complex, there are still exceptions and strategies available, such as paying a reasonable salary to family members for legitimate work performed for the practice. Navigating the TOSI rules requires careful planning to ensure compliance while still optimizing your family's overall tax position.

As your retained earnings grow and are invested within the corporation, they generate passive investment income (interest, dividends, and capital gains). The CRA has implemented rules that link a corporation's passive income to its eligibility for the small business deduction. If your dental corporation earns more than $50,000 in passive investment income in a given year, your access to the small business tax rate on your active dental income begins to grind $150,000 of passive income.

Managing this threshold is critical. Strategies include shifting investments toward growth-oriented assets that generate deferred capital gains rather than immediate interest or dividends, utilizing tax-exempt life insurance, or implementing an IPP to move funds out of the corporate investment portfolio. Effective management ensures that your active dental income continues to benefit from the lowest possible tax rate.

When addressing the challenges of the passive income threshold and the long-term extraction of retained earnings, corporate owned life insurance (COLI) is a premier strategy. A COLI policy allows your dental corporation to invest retained earnings into the tax-exempt investment component of a permanent life insurance policy. The growth within the policy does not count toward the $50,000 passive income threshold, protecting your small business deduction.

Furthermore, COLI provides a highly tax-efficient mechanism for wealth extraction. During your lifetime, you can access the cash value of the policy through an Insurance Funding Arrangement (IFA) or collateralized loan, providing tax-free cash flow. Upon death, the death benefit is paid to the corporation tax-free, and a significant portion (often the entire amount) is credited to the Capital Dividend Account.

This allows the funds to be paid out to your estate or heirs as a tax-free capital dividend, effectively bypassing the double taxation that often plagues corporate retained earnings at death.

If retained earnings are left inside your dental corporation until your death, they face a significant tax hurdle known as double taxation. First, there is a deemed disposition of your shares in the professional corporation, triggering a personal capital gains tax liability for your estate. Second, when the corporation eventually distributes those retained earnings to your heirs, the funds are taxed again as dividends. Proper estate planning for dentists is essential to mitigate this risk.

Strategies such as estate freezes, the use of family trusts, and the strategic implementation of COLI can help ensure that the wealth you have built within your practice is transferred to your beneficiaries efficiently, rather than being heavily eroded by taxes.

In Canada, you can take money out of your corporation's retained earnings by paying yourself a salary, declaring a dividend (eligible or non-eligible), or through a shareholder loan. Each method has distinct tax implications. Salary is deductible to the corporation and taxable to you personally, generating RRSP room. Dividends are paid from after-tax corporate income and receive a dividend tax credit personally. Shareholder loans must be repaid within a specific timeframe to avoid severe tax penalties.

A Canadian-controlled private corporation (CCPC), such as a dental professional corporation, can earn up to $500,000 of active business income subject to the lower small business tax rate(which varies by province but is generally around 12 $50,000 in the previous year. Income above the $500,000 threshold is taxed at the general corporate rate.

The choice between salary and dividends depends on your specific financial goals. A salary generates RRSP contribution room and requires CPP participation, which can be beneficial for long-term retirement planning. Dividends do not generate RRSP room or require CPP contributions, but they are taxed differently personally due to the dividend tax credit. Many dentists use a combination of both to optimize their personal tax brackets and retirement savings.

You cannot entirely avoid tax on retained earnings when withdrawing them for personal use, but you can minimize the tax burden. Strategies include utilizing the Capital Dividend Account (CDA) to pay tax-free capital dividends, implementing an Individual Pension Plan (IPP) to move funds into a tax-sheltered environment, and using Corporate-Owned Life Insurance (COLI) to facilitate tax-efficient wealth transfer to your estate.
