This is one of the most common points of confusion in Canadian small-business compliance, and it catches experienced bookkeepers as often as it catches owners. The words are almost the same. The forms both arrive once a year. Both feel like "the corporate filing."

They are completely unrelated. The T2 is an income tax return. The annual return is a corporate registry filing that has nothing to do with income, revenue, or tax at all β€” and the penalty for ignoring it isn't money, it's the end of your corporation's legal existence.

TL;DR β€” The Short Version
  1. The T2 is a tax return. Filed with the CRA under the Income Tax Act, due six months after your fiscal year-end, and it reports what the corporation earned.
  2. The annual return is a corporate-law filing. Filed with the registry that incorporated you β€” Corporations Canada or your provincial registry β€” due on your incorporation anniversary, and it reports nothing financial.
  3. The two clocks are unrelated. A corporation with a September year-end and a March incorporation date has deadlines six months apart. Neither reminds you of the other.
  4. Miss the T2 and you owe penalties and interest. Miss the annual return and you can be dissolved. The second consequence is far worse and far less understood.
  5. Ontario is where most of the confusion lives. Until May 15, 2021 the Ontario annual return was filed with the T2 on Schedule 546. It isn't anymore β€” it goes to the Ontario Business Registry, separately. A lot of corporations simply stopped filing it and never noticed.
  6. Whose job is it? Not automatically the tax preparer's. It's administrative registry work a bookkeeper can absolutely do β€” but it has to be named in somebody's engagement letter, or it falls straight through the crack between everyone.

Read on for what each filing actually is, what happens when the annual return is missed, the Ontario and Quebec wrinkles, and a practical answer on who should own it.


Two filings, two governments, two laws

Start here, because everything else follows from it. These filings serve entirely different purposes and answer to entirely different authorities.

A side-by-side comparison: the T2 corporate income tax return is filed with the CRA under the Income Tax Act, due six months after fiscal year-end, reports income, and carries penalties and interest if late. The annual return is filed with the corporate registry under corporate law, due on the incorporation anniversary, reports directors and registered office, and can result in dissolution if not filed. THE T2 RETURN a tax return THE ANNUAL RETURN a corporate registry filing GOES TO The Canada Revenue Agency UNDER The Income Tax Act CLOCK 6 months after fiscal year-end REPORTS Income, tax, financial statements IF YOU MISS IT Penalties and interest GOES TO Your incorporating registry UNDER Corporate law (CBCA or provincial) CLOCK Your incorporation anniversary REPORTS Directors, office, ownership IF YOU MISS IT Dissolution of the corporation
Nothing on the left tells you anything about the right. They share only the word "return."

The T2 is your corporation's income tax return. Every corporation resident in Canada must file one for every taxation year β€” within six months of the end of that year β€” even if it had no income, no activity, and owes no tax.

Source: Income Tax Act, s. 150(1)(a) β€” a corporation resident in Canada must file a return of income within six months after the end of the year.

The annual return is a corporate-law obligation owed to whichever registry brought your corporation into existence. For a federally incorporated company that's Corporations Canada; for a provincial company it's the provincial registry. It confirms that the public record about your corporation is still accurate: registered office address, directors, and β€” for federal corporations since January 22, 2024 β€” information about individuals with significant control.

Source: Canada Business Corporations Act, s. 263 β€” "Every corporation shall send to the Director an annual return in the form and within the period that the Director fixes." Corporations Canada fixes that period at 60 days following the anniversary date of incorporation, amalgamation or continuance.

Notice what the annual return does not ask for: revenue, profit, expenses, assets, or anything a bookkeeper would recognize as accounting. It's a governance filing. Its whole job is keeping the public register current so anyone dealing with your company β€” a bank, a supplier, a court β€” can find out who runs it and where to serve it.

Why the two deadlines have nothing to do with each other

This is the mechanical reason the annual return goes missing. Your T2 deadline is driven by your fiscal year-end β€” a date you or your accountant chose. Your annual return deadline is driven by your incorporation date β€” a date set by history and never revisited.

For most corporations those two dates are nowhere near each other. So the annual return comes due in the middle of an ordinary month, with no year-end activity around it, no accountant asking for records, and nothing else on the calendar to trigger the thought.

A timeline showing two independent annual cycles for an example corporation incorporated in March with a September fiscal year-end: the annual return is due within 60 days of the March anniversary, while the T2 is due six months after the September year-end, in March of the following year. TWO CLOCKS, ONE CORPORATION Example: incorporated 14 March Β· fiscal year-end 30 September JANMARMAY JULSEPNOV JANMARMAY JULSEP year 1 Β· year 2 Annual return due (May 13) Year-end (Sep 30) T2 due (Mar 31) Next annual return The registry never mentions your year-end. The CRA never mentions your anniversary.
The annual return arrives when nothing else is happening β€” which is exactly why it gets forgotten.

What actually happens when nobody files it

Late T2? You know that story β€” penalties and interest, unpleasant but survivable. The annual return works differently, because the registry isn't trying to collect money from you. It's deciding whether your corporation should continue to exist.

For a federal corporation, the law permits dissolution after one year of default. In practice, Corporations Canada's stated policy is to dissolve only after two years of unfiled annual returns, and to send a final notice first giving another 120 days to comply. Ignore that notice and the outcome is a Certificate of Dissolution.

Source: Corporations Canada, Policy on annual filings, and Corporations Canada resumes dissolutions of corporations in default. Dissolution is permitted under CBCA s. 212. Provincial registries have their own comparable processes.

Dissolution is not a filing problem. It's an existence problem. A dissolved corporation can't hold property, can't sue, and can't reliably contract. Banks freeze accounts when a corporate search comes back dissolved. Insurers can take the position that the named insured no longer exists. And the whole reason you incorporated β€” limited liability β€” becomes something you have to argue about rather than something you have.

It is fixable. Most jurisdictions allow revival, which restores the corporation retroactively. But it costs a fee, requires filing every missed annual return, and takes time you generally don't have when you discover it β€” because people almost always discover it in the middle of a financing, a sale, or a client's due-diligence request.

Why so many Ontario corporations quietly stopped filing

If you've ever been sure the annual return "gets done with the T2," you weren't imagining it. In Ontario, for years, it did.

Ontario corporations used to file their Corporations Information Act annual return as Schedule 546, attached to the T2, and the CRA passed the information along to the province. It was genuinely the accountant's job, because it was genuinely part of the tax return.

That ended on May 15, 2021. The CRA stopped accepting Ontario annual returns on the province's behalf, and the filing moved to the Ontario Business Registry β€” a separate system, with a separate login, that nobody's tax software touches.

Source: CRA, Important changes for corporations that file Ontario annual information returns β€” as of May 15, 2021 the CRA no longer accepts these returns on behalf of the Ontario Ministry; corporations with returns due after October 18, 2021 must file directly in the Ontario Business Registry. See also the Government of Ontario's Ontario Business Registry, which now handles the filing.

Here's why that change did so much damage: nothing broke visibly. Schedule 546 simply stopped being part of the T2, tax software stopped prompting for it, and the annual return became nobody's task. The accountant reasonably assumed it was no longer in scope, because it no longer was. The owner never knew it existed as a separate thing. Years of non-filing accumulate in complete silence β€” until a lawyer runs a corporate search.

Where it is still bundled with the tax return

Quebec runs the model Ontario abandoned. A Quebec corporation's dΓ©claration de mise Γ  jour annuelle (annual updating declaration) to the Registraire des entreprises can still be filed together with the CO-17 corporate income tax return β€” if the corporation is "paired" and the registry information is already accurate, you simply tick the box at line 39 of the CO-17.

Source: Revenu QuΓ©bec, Annual Updating Declaration, and Gouvernement du QuΓ©bec, Annual updating declaration.

The catch is that ticking the box certifies the register is accurate. If a director changed, an address moved, or a shareholder was added and the register was never updated, ticking "yes" doesn't make it true β€” it just files an inaccurate declaration. The information has to be corrected through the Registraire's own service first.

So even in the one province where the two filings travel together, someone still has to actually check the underlying facts each year.

Find your registry before you look for the deadline

The single most useful thing to establish is which registry incorporated the company, because that determines everything else. It is on the certificate of incorporation, and it does not change unless the corporation is continued into another jurisdiction.

Whatever the jurisdiction, the anniversary date β€” not the year-end β€” is the date that belongs in the calendar.

Is this the bookkeeper's job or the tax preparer's?

This is the question that generates the most argument, and it deserves a straight answer rather than a diplomatic one.

It is not tax preparation. The annual return isn't filed under the Income Tax Act, doesn't report income, and isn't produced by tax software. A tax preparer who says "that's not part of my engagement" is being accurate, not evasive. Outside Quebec, it genuinely isn't part of preparing a T2.

It is not restricted work. No professional designation is required to file an annual return. It's an online form that takes about ten minutes and costs a small fee. A bookkeeper can absolutely do it, and there's a strong practical argument that a bookkeeper should: you're the one with recurring contact, an existing calendar of client deadlines, and the habit of filing things on time.

What it is, is high-consequence. That's the asymmetry to respect. Ten minutes of easy administrative work, and the downside of skipping it is the dissolution of your client's company. Tasks with that shape need an owner in writing β€” not a shared assumption.

Nothing gets missed as reliably as a task that three competent professionals each assume one of the others is handling.

If you're a bookkeeper deciding whether to take it on, here's how I'd draw the lines:

And if you're the owner reading this: the answer to "who files my annual return?" should be a name, not a shrug. If nobody can produce one, it's you.

Warren found out from his bank

Meet Warren, who runs Glenmore Drywall Ltd., a nine-person drywall and taping contractor in Whitby, Ontario. Incorporated provincially in 2016. Clean books, T2s filed on time every year by a competent accountant, GST/HST current, payroll current. By every measure Warren was a well-run, compliant small business.

In 2022 he went to refinance equipment. The lender ran a corporate search as a routine condition and came back with a problem: Glenmore Drywall Ltd. was showing as in default on its annual returns with the province, and had been since 2021.

Nobody had done anything wrong, exactly. Before May 2021 the annual return had ridden along on Schedule 546 with the T2, so it had always simply happened. When that stopped, the accountant's software stopped producing it β€” correctly, since it was no longer part of the T2 β€” and nobody told Warren that a filing had detached itself and become his responsibility. He'd never heard the phrase "annual return" as something distinct from his tax return in his life.

The filing didn't fail because someone was careless. It failed because it stopped being anyone's job, and the change was invisible from every seat.

The financing was delayed several weeks while the missed returns were filed and the registry record was brought current. Warren caught it in time β€” the corporation was never dissolved. But he spent the delay explaining to a lender why his company appeared to be in default, which is not a conversation you want in the middle of a credit decision.

What should have happened

One line in one engagement letter, and one recurring calendar entry against the incorporation anniversary. That's the entire fix, and it costs a few minutes a year.

When we onboard a corporate client now, confirming the registry standing is part of the intake β€” which registry, what the anniversary date is, when the last annual return was filed, and, in writing, who is filing the next one. About a fifth of the corporations we've picked up in Ontario since 2021 have had at least one missed year. Almost none of them knew.

Two filings, two owners, both named

The T2 tells the CRA what your corporation earned. The annual return tells the world your corporation still exists and who is behind it. They're answerable to different governments on different clocks, and only one of them can quietly end your company.

You don't need to become an expert in corporate law to handle this. You need to know which registry you belong to, when your anniversary falls, and β€” in writing β€” whose job it is. Any bookkeeper can carry it. What can't carry it is an assumption.

Not sure whether your annual returns are current?
