Business vs. Personal Tax: Where Do You Draw the Line?

“Do I file this as personal income, or does it belong to the business?”

At Blue Ocean, this is one of the most frequent questions we encounter. Take Carl, for example. Carl is a driven entrepreneur running a growing corporation. Like many business owners, he initially assumed that personal and business taxes were just two sides of the same coin.

However, as his revenue grew and his professional expenses began to overlap with his personal life, the lines blurred. He found himself in a maze of "what-ifs" and "how-tos." Carl isn't alone—managing the intersection of personal and corporate tax is one of the most significant challenges for Canadian business owners. Understanding this boundary is the first step toward financial confidence and stress-free compliance.

The Corporate Entity: A Person in the Eyes of the Law

The most important distinction for Carl was realizing that his corporation is its own legal entity. When you incorporate, the business becomes a "person" separate from you.

• Responsibility: The corporation reports its own income, claims its own expenses, and pays its own taxes.

• Separation: Even though Carl owns 100% of the company, the money inside the corporation belongs to the corporation until it is paid out to him as a salary or dividend.
  

The Personal Side: You as an Individual

Personal taxes apply to you as a human being. This includes your salary from the corporation, investment income, or any other personal revenue streams. In Canada, we use a progressive tax system, meaning your tax rate climbs as your income increases.

The Big Three: Key Differences at a Glance

1. Tax Rates: Flat vs. Progressive

One of the biggest eye-openers for Carl was how the rates differ.

• Corporate: These rates are generally lower to encourage business growth. Federally, the general rate is 15%, but many small businesses qualify for a reduced rate of 9% on the first $500,000 of income.

• Personal: Personal income is taxed in "brackets." The more you earn, the higher the percentage you pay on those top dollars.

2026 Federal Personal Tax Brackets:

• 15% on the first $58,523

• 20.5% on $58,523 to $117,045

• 26% on $117,045 to $181,440

• 29% on $181,440 to $258,482

• 33% on everything above $258,482

Note: In Nova Scotia, provincial rates (ranging from 8.79% to 21%) are added on top of these federal figures.

2. The Logistics of Filing

Keeping your calendar straight is half the battle.

• Corporations: Must file a T2 return every year within six months of their fiscal year-end.

• Individuals: Generally file by April 30 (or June 15 if self-employed). However, regardless of the filing deadline, any taxes owed to the CRA are typically due by April 30 to avoid interest.
  

3. Deductions: What Can You Claim?

• Personal Deductions: Think RRSP contributions, medical expenses, tuition credits, and the basic personal amount.

• Business Deductions: These are costs incurred to earn income, such as rent, salaries, utilities, and the Capital Cost Allowance (CCA) for equipment.

For Carl, learning which expenses were "business-use" versus "personal-use" saved him from potential audits and significantly improved his company’s cash flow.
