If you run an incorporated business in Ontario, you are required to file a T2 corporate tax return every year. It does not matter whether you made money or not, whether you were active or not, or whether you paid yourself anything. The T2 is mandatory for every corporation in Canada.
Yet many incorporated professionals treat it as an afterthought, hand a shoebox of receipts to their accountant in June, and hope for the best. That approach is costing them money every single year.
What Is a T2 Corporate Tax Return?
The T2 is the annual income tax return filed by Canadian corporations. It reports your corporation’s income, expenses, deductions, and the amount of tax owed to the Canada Revenue Agency. Unlike a personal T1, the T2 covers your business entity as a separate legal person.
For an incorporated professional in Ontario, your T2 is typically due six months after your fiscal year end. If your year ends December 31, your T2 is due June 30. The tax payment itself is due three months after year end, which is March 31 in this case. These are two different deadlines and missing either one has consequences.
What Goes Into a T2?
A properly prepared T2 includes:
- Total corporate revenue for the year
- All deductible business expenses, properly categorized
- Capital cost allowance (CCA) for any equipment or assets
- Salary and dividends paid to shareholders
- Corporate income tax calculation
- Small Business Deduction if applicable
- Year-end financial statements (Balance Sheet, Income Statement)
Why Your T2 Is Worth More Than Just Filing It
Most incorporated professionals think of the T2 as a compliance requirement. File it, pay what you owe, move on. That is the wrong way to look at it.
Your T2 is a planning document. The decisions made before filing — how much salary versus dividends you took, what capital purchases you made, how expenses were categorized — determine what your tax bill looks like. By the time your accountant is preparing the return, most of those decisions are already locked in.
This is why working with an accountant year-round matters, not just at filing time.
Common Deductions Incorporated Professionals Miss
- Home office expenses if you work from home
- Vehicle expenses with proper mileage logs
- Professional development and courses
- Software subscriptions used for business
- Meals and entertainment with proper documentation
- Life insurance premiums in certain structures
- Health spending accounts
What Happens If Your T2 Has Errors?
CRA can reassess your T2 up to three years after the original assessment date. If they find errors, you will owe additional tax plus interest at the current CRA rate of 9% annually. If CRA believes there was misrepresentation, there is no time limit on reassessment.
A correctly prepared T2 from a CPA is not just a filing. It is protection.
Professional Corporations in Ontario
Dentists, doctors, lawyers, and other regulated professionals often incorporate through a Professional Corporation (PC). These have specific CRA rules around income splitting, passive investment income, and the small business deduction that differ from standard corporations. If you have a PC, make sure your accountant understands the specific requirements.
