If you’ve incorporated your medical practice, you likely did so to reduce tax and save more for retirement.
While it's true that a professional corporation can be a way to shelter your earnings in any given year, you may also find that smart use of RRSPs and TFSAs can help you keep more of your money.
Passive income rules explained
When you’re incorporated, some of your professional earnings may be eligible to be taxed at the small business tax rate, which is about 12% but varies by province or territory.
Many incorporated physicians retain professional earnings in their corporate accounts, and this money generates passive income. Passive income includes interest, dividends, mutual fund income, capital gains and most real-estate rental income.
If your medical professional corporation earns too much passive income, this could limit access to the small business tax rate on your professional earnings.
You can use the following formula1 to calculate how much passive income your corporation may earn before your access to the small business tax rate is reduced1:
For example, if your corporation has $350,000 of professional income from your practice, your passive income must stay below $80,000 ($150,000 – [$350,000/5]) to avoid a higher tax rate on your professional income.
RRSPs and TFSAs can help you keep more of your money
Here's where RRSPs and TFSAs come into play. By paying yourself a higher salary, you can reduce your corporate net professional income. With less money retained in your corporation, it reduces the size of your corporate portfolio, thereby generating less passive income.
Paying yourself a salary also creates RRSP contribution room that allows you to shelter more money now (as RRSP contributions are deductible from your personal income) and defer paying taxes on it until you withdraw it in retirement (presumably at a time when you are in a lower tax bracket than you are today). To make the maximum allowable RRSP contribution of $30,780 in 2023, you would need to have earned a salary worth at least $171,00 in 2022.
Another way to reduce the passive income being earned in your corporation is to take the funds out of the corporation and contribute them to your TFSA. If you’ve been eligible but have never contributed to a TFSA before, the cumulative amount you can contribute before the end of 2023 is $88,000 (the TFSA annual limit for 2023 is $6,500).
When you take the money out of the corporation to contribute to your TFSA, you will pay tax upfront. But once the money is in the TFSA, all income earned within the TFSA is not taxable, making it a powerful savings tool.
Over the long term, the benefits of getting tax-free earnings from your TFSA will often be greater than the current tax savings you would get from retaining money in your corporation.
You have options when it comes to saving your excess earnings. It may not make sense to continue leaving all of your investment income in your corporation after all, particularly if your corporation's investment account has grown to the point where you’re affected by the passive income rules.

1 This formula is valid for net professional income of $500,000 or less. Any net professional income above $500,000 would not benefit from the small business tax rate.
