In Canada, the two most common tax returns are the T1 (personal income tax return) and the T2 (corporate income tax return). If you own a business, you might need to file one or both. Understanding the differences between these two returns is critical for staying compliant and minimizing your tax bill.
What Is a T1 Tax Return?
The T1 General is the personal income tax return that all Canadian residents file annually. It reports your total income from all sources, including employment income, self-employment income, rental income, investment income, and capital gains.
If you're a sole proprietor or self-employed individual, your business income is reported on your T1 using the T2125 Statement of Business or Professional Activities. This means your business income and personal income are taxed together at personal tax rates.
T1 Key Details
- Who files: All Canadian residents with income
- Deadline: April 30 (June 15 for self-employed individuals, but any balance owing is still due April 30)
- Tax rates: Personal marginal rates ranging from 20.05% to 53.53% in Ontario (combined federal and provincial)
- Business income: Reported on T2125 as part of your personal return
What Is a T2 Tax Return?
The T2 Corporation Income Tax Return is filed by incorporated businesses in Canada. When you incorporate, your business becomes a separate legal entity with its own tax obligations. The corporation files its own tax return and pays taxes at corporate rates, which are significantly lower than personal rates.
Even if your corporation has no revenue or is inactive, you must still file a T2 return every year. Failure to file can result in penalties and loss of your corporation's good standing.
T2 Key Details
- Who files: All incorporated businesses in Canada
- Deadline: Six months after the corporation's fiscal year-end
- Payment deadline: Two or three months after fiscal year-end (depending on CCPC status and taxable income)
- Tax rates: 12.2% for small businesses in Ontario (on the first $500,000 of active business income) or 26.5% for larger corporations
T1 vs T2: Key Differences
Tax Rates
The most significant difference is the tax rate. Personal tax rates in Ontario can reach 53.53% on high income, while the small business corporate tax rate is just 12.2%. This rate difference is one of the main reasons business owners incorporate — to defer taxes on income they don't need for personal expenses.
Filing Deadlines
T1 returns follow a fixed deadline: April 30 each year (June 15 for self-employed). T2 returns are due six months after your corporation's fiscal year-end, which can be any date you choose when you incorporate. This gives corporations more flexibility in tax planning.
Income Splitting
Corporations offer income splitting opportunities through dividends paid to family members who are shareholders. While the Tax on Split Income (TOSI) rules have limited some strategies, there are still legitimate ways to distribute income among family members through a corporation.
Retained Earnings
With a T1, all business income is taxed in the year it's earned, regardless of whether you withdraw it. With a T2, you can leave profits in the corporation and pay the lower corporate tax rate. You only pay personal tax when you withdraw funds as salary or dividends.
Which One Do You Need?
If you're a sole proprietor, freelancer, or self-employed individual, you file a T1. If you've incorporated your business, you file a T2 for the corporation and a T1 for your personal income (including any salary or dividends you pay yourself from the corporation).
Many business owners file both — the T2 for their corporation and a T1 for their personal taxes. Your accountant can help you optimize the split between salary and dividends to minimize your overall tax burden.
Bottom Line
The T1 is your personal tax return, and the T2 is your corporate tax return. If you're incorporated, you need both. The corporate T2 offers lower tax rates and more flexibility, but comes with additional compliance requirements. A qualified accountant can help you navigate both returns and structure your compensation to minimize taxes.
