It's one of the most frequently repeated mistakes we see among Calgary business owners: "My corporation didn't earn any income this year, so I don't have to file a return." This belief is understandable — if there's nothing to report, why file? But it is incorrect, and it can lead to penalties, interest, and CRA collection activity that creates significant headaches down the road.
Under the Income Tax Act, every Canadian corporation must file a T2 corporate income tax return for every year it exists — even if it earned no income, had no expenses, and conducted zero business activity. A corporation that was incorporated but never used, a shell company being kept in reserve, or a business that wound down operations mid-year but wasn't formally dissolved all have T2 filing obligations.
A "nil return" is simply a T2 return filed for a corporation that has no taxable income and owes no tax. The return still requires the completion of the standard T2 form, including basic financial statements (a balance sheet showing the corporation's assets, liabilities, and equity — even if all figures are zero), and often Schedule 50 (shareholder information).
Despite being called "nil," these returns aren't optional. They establish the corporation's compliance record with the CRA, maintain the corporation's good standing, and document the years in which the corporation was inactive — which matters if you later reactivate the company or wind it up.
The obligation continues until the corporation is formally dissolved. Many business owners assume that simply stopping operations ends the obligation. It does not. As long as the corporation exists legally — as registered with Corporations Canada (for federal corporations) or with Service Alberta (for Alberta provincial corporations) — it must file annual T2 returns.
We regularly work with clients who have accumulated five or ten years of unfiled T2 returns for a corporation they thought was "done." Getting compliant usually involves filing all outstanding returns (as nil returns where appropriate), addressing any outstanding penalties, and then formally dissolving the corporation if it's no longer needed.
Very few. The Income Tax Act does provide that a corporation is not required to file a T2 if it was both incorporated and dissolved in the same year — meaning it never had a full fiscal year in existence. Beyond this narrow exception, the filing obligation applies universally to Canadian corporations.
Non-resident corporations with Canadian operations, foreign subsidiaries operating in Canada, and Crown corporations all have their own specific rules that may differ — but for the typical small or medium-sized Alberta corporation, the rule is clear: file every year, without exception.
If a corporation has genuinely served its purpose and you want to stop the annual filing obligations, the correct process is formal dissolution — not simply abandonment. Proper dissolution involves:
If you have an inactive corporation with unfiled T2 returns — whether one year or many — the best course of action is to get current as soon as possible. CRA generally treats proactive compliance more favourably than waiting for a demand letter. In some cases, the Voluntary Disclosures Program (VDP) may allow Calgary incorporated businesses to come forward with outstanding returns while reducing or eliminating penalties. For ongoing corporate tax obligations including active corporations, our corporate tax services cover T2 preparation, planning, and CRA compliance year-round.
