Corporate tax savings: Smart strategies to keep more money in your business

Corporate insurance

1. Corporate-owned life insurance: Your "no-limit corporate TFSA"

Corporations can’t have Tax-Free Savings Accounts (TFSAs), which are registered accounts designed for individuals. But corporate-owned life insurance has some features similar to a TFSA. Namely, that you can use it to grow and withdraw your money tax-free.

Here are some of the advantages of corporate-owned life insurance:

Money that grows within the policy is tax-exempt.
Investment income in certain policies is exempt from the federal $50,000 passive income limit that could reduce your company’s access to the small business deduction.
You can access the cash value of the policy through withdrawals or tax-free loans.
When you (or the key person insured by the policy) die, a tax-free death benefit goes to your Capital Dividend Account (CDA). From there, your company can pay a tax-free distribution to shareholders.

2. Split-dollar critical illness insurance: A shared-ownership approach for business owners

For incorporated business owners and their key people, a critical illness can create two problems at once: a personal health event and a hit to the business that depends on you. A shared-ownership ("split-dollar") critical illness strategy is one approach some owners use to address both.

In broad terms, the corporation and the insured each hold a different interest in the same policy.

The corporation typically owns and pays for the critical illness coverage. If the insured is later diagnosed with a covered condition, the benefit is paid to the corporation, where it can help fund operations, cover a shortfall, or bring in support during a recovery.
The insured typically pays for an optional return-of-premium rider, which may refund premiums if certain conditions are met and no claim has been made.

It's a flexible approach, but it’s also complex. How the premiums are split, how the arrangement is documented, and how any payment is ultimately taxed all depend on the specific facts, the policy, and current tax rules. These details are important, and getting them wrong can change the outcome significantly.

That’s why this is a strategy to explore together. We’re not accountants and this isn’t tax advice, but we can work alongside your accountant and tax advisor to assess whether a shared-ownership approach fits your situation and is structured appropriately.

Individual pension plans: Beyond the traditional RRSP

An Individual Pension Plan (IPP) is a powerful retirement savings option, especially if you’re an incorporated business owner older than 40 with a T4 income of more than $100,000. Think of an IPP as a supercharged RRSP. It’s designed for business owners like you, with extra perks and benefits, including:

Higher contribution limits — up to 65% more than RRSPs, helping you maximize your retirement savings.
Tax-deductible deposits — contributions to an IPP are tax-deductible for your corporation, enhancing the tax efficiency of your business.
Defined benefits — unlike RRSPs, IPPs offer a defined benefit once you retire, providing a predictable stream of income.
IPPs don’t count toward the $50,000 federal passive income limit.

Although IPPs come with lots of perks and benefits, they also come with important considerations. IPPs require actuarial calculations and have higher administrative costs, so it’s important to determine whether the benefits outweigh the setup and maintenance costs. We can help you run the numbers and see if an IPP is right for you.

Maximizing business expense deductions

Corporate insurance and retirement savings vehicles aren’t the only ways to lower your corporate taxes. Maximizing business expense deductions can go a long way toward minimizing your tax bill.

Eligible expenses that can reduce your corporate taxable income include:

Salaries and wages
Travel expenses
Management and administrative fees
Bank and interest charges
Overhead expenses
Office supplies and equipment

It can be tempting to deduct anything and everything. But it’s important to do your homework and make sure your deductions are for legitimate business expenses.

Follow these best practices for managing your expenses and deductions:

Maintain detailed records — keep your receipts and track your expenses throughout the year.
Understand qualification criteria — know what counts as a legitimate business expense and what doesn’t.
Review your finances regularly and consult your financial, tax, and legal professionals as needed.
Stay current with changes to tax laws to ensure you remain compliant and informed.

Smart investment strategies within your corporation

Investing can provide long-term growth for your business, but there are special considerations that come with corporate investing, particularly the distinction between active income and passive income.

Active income is money earned through your core business activities, such as professional service fees or profits from your business operations. Passive income is money earned outside of those activities and typically includes investment earnings, dividends, and rental income.

Managing corporate passive income is crucial. In many cases, passive investment income earned within a corporation can be taxed at rates exceeding 50%. By comparison, active business income may qualify for lower small business tax rates — a reduced federal tax rate of 9%, plus applicable provincial tax rates.

In Ontario, this results in a combined small business tax rate of 12.2% on the first $500,000 of active business income, while income above that threshold is generally taxed at the higher general corporate rate of 26.5%.¹

While your corporation can’t use TFSAs or RRSPs, corporate-owned insurance and IPPs can help lower your tax burden. Strategic portfolio construction also plays an important role, and we can help.

Creating a comprehensive tax strategy

While there are many insurance, investment, deduction, and savings options available to help reduce your tax burden, it’s important to have the right mix of strategies working together.

1. Using multiple strategies

Combine different approaches for optimal results.
Balance your immediate business needs with long-term planning.
Regularly review your strategies and adjust as needed.

2. Collaborating with professionals

Work with tax specialists.
Consult financial planners and insurance professionals (that’s us!).
Meet regularly with your accountant to ensure your business financials are on track.

3. Documentation and compliance

Maintain detailed records.
Stay current with tax laws.
Be prepared for audits.
Clearly document your financial policies.

4. Regularly reviewing and adjusting your tax strategies

Conduct an annual strategy assessment to ensure your current approaches still make sense.
Monitor market conditions with the help of your professional advisors.
Make sure your tax strategies evolve alongside your business growth.

The bottom line

Effective corporate tax planning isn’t about using a single strategy — it’s about implementing a comprehensive approach that aligns with your business goals while maximizing tax efficiency. The key is finding the right mix of strategies that work for your specific situation.
