Every Canadian corporation files a T2 Corporation Income Tax Return every year, whether it made C$2 million, lost money or did nothing at all. Most owners of small corporations meet the T2 for the first time when their accountant sends a bill, and many don't realise the tax is due months before the return. This guide is for owners and new directors of small Canadian corporations in 2026. It covers who must file, the filing and payment deadlines, the schedules a typical small company uses, nil returns for inactive companies, where the T2 Short Return stands now, electronic filing, penalties, and a worked example with dates and dollars.

Quick answer

The T2 is due six months after the tax year-end, but the tax is due earlier — two months after year-end, or three months after year-end for a Canadian-controlled private corporation that claims the small business deduction and stayed within its business limit last year. Every resident corporation files, even with no income, and almost all must file electronically.

  • 31 December year-end: tax by 31 March (qualifying CCPC), return by 30 June

  • Inactive companies still file a T2 every year

  • Not e-filing when required: C$1,000 penalty

  • Late filing with tax owing: 5% of the unpaid tax plus 1% for each complete month late, up to 12 months

What the T2 is and who has to file

The T2 is the federal corporate income tax return. It reports the corporation's income, converts accounting profit into taxable income, applies deductions such as the small business deduction, and calculates federal tax. Corporations in every province and territory except Alberta and Quebec also use the T2 to report provincial or territorial tax — Ontario, BC or Nova Scotia tax is worked out on schedules inside the T2 and paid to the CRA with the federal amount.

The CRA's rule is simple: every resident corporation files a T2 for every tax year, even if it has no tax payable. That explicitly includes inactive corporations, non-profit organizations and tax-exempt corporations. The only exceptions are tax-exempt Crown corporations, Hutterite colonies and registered charities, which file their own returns. A non-resident corporation files if at any time in the year it carried on business in Canada, had a taxable capital gain or disposed of taxable Canadian property.

The return belongs to the corporation, not to you. Your salary or dividends from the company go on your personal T1, and the company reports what it paid on T4 or T5 slips. Keeping these two layers apart is the first thing new owners have to get used to. Our incorporation guide explains why the corporation is a separate taxpayer.

Alberta and Quebec. A corporation with a permanent establishment in Alberta or Quebec files a separate provincial return as well as the T2. In Alberta that is the AT1, filed with Alberta's Tax and Revenue Administration within six months of year-end; for tax years beginning after 31 December 2024 it must be filed electronically through Alberta's Net File, with a C$1,000 penalty for not doing so. Quebec corporations file their provincial return with Revenu Québec.

The two deadlines: filing day and balance-due day

This is where most small corporations get caught. There are two different dates, and the earlier one is about money.

Filing deadline. File within six months after the tax year-end. If the year ends on the last day of a month, the return is due on the last day of the sixth month after it; otherwise it's due on the same day of the sixth month. The CRA's own examples: a 31 March year-end files by 30 September; 31 August files by 28 February; a year ending 23 September files by 23 March. If the due date falls on a weekend or a public holiday the CRA recognises, the return is on time if received or postmarked by the next business day.

Balance-due day. Tax owing is due two months after year-end for most corporations. A corporation gets three months after year-end if all of these apply:

  1. it was a Canadian-controlled private corporation (CCPC) throughout the tax year;
  2. it claims the small business deduction for the year, or was allowed it in the previous year; and
  3. its taxable income for the previous year didn't exceed its business limit — or, if it's associated with other corporations, their combined taxable income for their last tax years ending in the previous calendar year didn't exceed their combined business limits.

Interest on unpaid tax starts the day after the balance-due day, not after the filing deadline. An owner who files on time in June but pays then has already run up three months of interest on a 31 December year-end. Interest compounds daily at a prescribed rate set every quarter.

Instalments during the year

Corporations generally pay tax in instalments through the year rather than all at the end. Instalments aren't required when the corporation's tax for either the current year or the previous year is C$3,000 or less, and a new corporation doesn't pay them in its first tax year.

Monthly is the default. The first payment is due one month less a day after the tax year starts, and the rest on the same day of each following month.

Quarterly for small CCPCs. A CCPC may pay quarterly instead if it has a perfect compliance history for the previous 12 months — GST/HST, source deductions, CPP and EI remitted on time, and income tax and GST/HST returns filed on time — and, together with associated corporations, its taxable income is C$500,000 or less and its taxable capital employed in Canada is C$10 million or less for the current or previous year.

Missed or short instalments attract daily-compounded instalment interest. A separate instalment penalty only kicks in if that interest exceeds C$1,000. You can see your instalment schedule and pay through My Business Account using the corporation's RC account number — our business number guide explains how the RC account attaches to the BN.

What goes into a T2: the core schedules

The T2 itself is a nine-page return, but the work happens on the schedules behind it. The CRA's T2 guide (T4012) lists more than a hundred, most of which a small corporation never touches. These are the ones a typical small, single-province CCPC files.

ScheduleWhat it doesWho needs it
GIFI 100Balance sheetAlmost every corporation
GIFI 125Income statementAlmost every corporation
GIFI 141Notes checklist: who prepared the statements and howAlmost every corporation
Schedule 1Converts accounting income to net income for tax purposesAny corporation with adjustments — most
Schedule 8Capital cost allowance (tax depreciation)Corporations with equipment, vehicles, computers, buildings
Schedule 50Shareholder informationPrivate corporations with a shareholder holding 10% or more
Schedule 7Active business and investment incomeCCPCs claiming the small business deduction
Schedule 9 / 23Related and associated corporations; sharing the business limitGroups of related companies
Schedule 3Dividends received and paidCorporations paying or receiving taxable dividends
Schedule 5Allocating income between provinces; provincial credits and other taxesCorporations in more than one province, or claiming provincial credits

GIFI instead of paper statements. The General Index of Financial Information is a standard code list for balance sheet and income statement lines. If you file electronically you don't send paper financial statements, but you should include any notes and the accountant's report through GIFI.

The first return is longer. A new corporation's first T2 also needs Schedule 101, an opening balance sheet, and details of any shares issued for something other than cash — for example a sole proprietor rolling equipment into the company.

Foreign property. If the corporation held specified foreign property costing more than C$100,000 at any time in the year, it also files Form T1135. Foreign investments held through Canadian mutual funds, and property used only in its active business, don't count.

The small business deduction. This is where most of a small CCPC's tax saving comes from: a reduction that brings the federal rate on the first C$500,000 of active business income down to 9%, against the 15% general rate. Our small business tax rate guide sets out each province's rate, the passive-income grind and how associated corporations share the limit.

Nil returns and inactive corporations

There is no special "nil return" form. An inactive corporation files the same T2 as everyone else, with GIFI showing its balance sheet (often just share capital and perhaps a shareholder loan) and zero revenue and expenses. Because the T2 is now e-filed for nearly every corporation, you still prepare it in certified software.

Why bother when nothing happened? Because the obligation doesn't depend on activity. If you don't file, the CRA can issue a demand to file, and a corporation that ignores demands builds a compliance record that later costs it the quarterly-instalment option, slows GST/HST refunds and can lead to an assessment based on the CRA's estimate. If you have no intention of using the company again, dissolving it is usually cheaper than filing nil returns for years — but file the final T2 up to the dissolution date first.

A common mistake is assuming a company with no tax payable faces no penalty. Strictly, the section 162 late-filing penalty is a percentage of unpaid tax, so it is nil when nothing is owed. But the C$1,000 penalty for not filing electronically doesn't depend on tax owing, and a paper nil return can trigger it.

The T2 Short Return: still listed, rarely the right choice

The CRA still describes two printable returns: the full T2 and the T2 Short. The short form is two pages plus Schedule 1, with Schedule 8 and Schedule 50 where needed. Under the T2 guide, two kinds of corporation can use it: a CCPC throughout the year with nil net income or a loss for tax purposes, and a corporation exempt from tax under section 149, such as a non-profit. In both cases the corporation must also have a permanent establishment in only one province or territory, claim no refundable tax credits other than a refund of instalments, not have received or paid taxable dividends, report in Canadian dollars, and meet two other technical tests.

The catch is electronic filing. For tax years starting after 2023 all corporations must file their T2 electronically, except insurance corporations, non-resident corporations, corporations reporting in a functional currency and corporations exempt from tax under section 149. The T2 guide says plainly that CCPCs must file electronically or face the penalty. The T2 Short available on canada.ca is the 2019 printable form. So for a CCPC with a nil or loss year, the practical route is to file a full T2 through certified software — many packages make a nil return quick. The short form remains most relevant to tax-exempt corporations, which are outside the e-filing rule.

How to file a T2 electronically

You need software the CRA has certified for Corporation Internet Filing. Some commercial packages are designed for accountants; a few are priced for owners filing one simple return. Once the return is prepared you can transmit it:

  • through the CRA's Corporation Internet Filing service from inside the software;
  • through My Business Account, using "Transmit a return", if you're the owner — no web access code needed; or
  • through Represent a Client if you're an authorised representative or employee.

Filing your corporation's T2

  1. 1

    Close the books for the year

    Reconcile bank and credit card accounts, record shareholder loans, and finalise the balance sheet and income statement.

    Tip: Your fiscal year-end is fixed once chosen; changing it later needs CRA approval.

  2. 2

    Prepare the return in certified software

    Enter GIFI financial statements, then Schedule 1 adjustments, Schedule 8 CCA, Schedule 50 and the small business deduction schedules.

  3. 3

    Pay the balance by the balance-due day

    Pay three months after year-end (qualifying CCPC) or two months after year-end after year-end through online banking or My Business Account, even if the return isn't finished.

  4. 4

    Sign Form T183 CORP if someone else transmits

    Your accountant keeps the signed authorisation; it isn't sent to the CRA.

  5. 5

    Transmit by the six-month deadline

    File through the software, My Business Account or Represent a Client, and keep the confirmation number.

  6. 6

    Check the notice of assessment

    Compare it with what you filed. If it differs, you can file a notice of objection within the time limit.

The software also asks for a NAICS code describing the corporation's main revenue-generating activity. Choose carefully the first year — it carries forward. If you genuinely can't file electronically, the CRA still accepts a printed T2 bar-code return, but the electronic-filing penalty applies to it.

Penalties and how to avoid them

Late filing. Section 162(1) of the Income Tax Act charges 5% of the unpaid tax plus 1% for each complete month late, up to 12 months. Section 162(2) raises it to 10% of the unpaid tax plus 2% for each complete month late, up to 20 months where the CRA has issued a demand to file and the corporation was already penalised for late filing in any of the three previous tax years.

Not filing electronically. C$1,000 under section 162(7.2), whatever the tax owing.

Unreported income. If a corporation fails to report C$500 or more of income in a year and also did so in any of the three previous years, a repeated-failure penalty applies. Knowingly or grossly negligently making a false statement carries a penalty of the greater of C$100 and 50% of the understated tax.

Large corporations — those whose taxable capital employed in Canada with related companies exceeds C$10 million — face an additional monthly late-filing penalty based on capital, up to 40 months. That rarely touches small businesses.

Relief. The CRA can cancel or waive penalties and interest when circumstances beyond your control stopped you from filing or paying — serious illness, a natural disaster, a CRA error. Requests go through My Business Account or Form RC4288 and must relate to the last 10 calendar years. If you haven't filed for several years, the Voluntary Disclosures Program can reduce penalties provided you come forward before the CRA contacts you.

Worked example: an Ontario consulting company

Northbay Consulting Inc. is an Ontario CCPC owned by one person, with a 31 March year-end and no associated companies. For the year ended 31 March 2026 it has active business income — and taxable income — of C$120,000. It claimed the small business deduction last year and its prior-year taxable income was well under C$500,000.

Tax. Federal tax at the small business rate of 9% is C$10,800. Ontario's lower rate was 3.2% for days before 1 July 2026, and the whole year falls before that date, so Ontario tax is C$3,840. Total corporate tax: C$14,640. (For a year that straddles 1 July 2026, Ontario's new 2.2% rate is blended in by days.)

Dates. Because it meets the CCPC conditions, the balance of tax is due three months after year-end — 30 June 2026. The T2 is due six months after — 30 September 2026. Last year's tax was over C$3,000, so for the year that began 1 April 2026 it pays instalments; with a clean compliance record and taxable income under C$500,000, it can pay quarterly.

If it files late. Suppose the owner paid nothing and filed on 15 February 2027. The return is four complete months late (30 October, 30 November, 30 December and 30 January have passed). The late-filing penalty is 5% × C$14,640 = C$732, plus 4% × C$14,640 = C$585.60 — C$1,317.60 — on top of daily-compounded interest running since 1 July 2026. Had it paid the C$14,640 on 30 June, the late-filing penalty would have been nil, because it is calculated on unpaid tax.

The lesson. Pay on the balance-due day using an estimate even if the books aren't finished; the T2 can follow. Our break-even calculator and profit margin calculator help you estimate profit — and so the tax — before year-end.

Common mistakes

Treating six months as the payment date. It's the filing date. Interest starts after two or three months.

Skipping years when the company is dormant. The obligation continues. File nil returns or dissolve properly.

Filing the T2 Short on paper. A CCPC that mails the short form risks the C$1,000 e-filing penalty.

Mixing personal and corporate money. Personal expenses paid by the company end up as shareholder loans or taxable benefits. Schedule 1 and the shareholder loan rules make that expensive.

Forgetting the association rules. Two companies controlled by the same person or family generally share one C$500,000 business limit. Claiming it twice leads to reassessment.

Ignoring the provincial return in Alberta. An Alberta corporation that files only the T2 hasn't finished.

What to do next

Put both deadlines for your year-end in your calendar now, and set aside tax monthly so the balance-due day isn't a shock. If you're still deciding whether to incorporate, compare the costs in our incorporation guide and the rates in our small business tax rate guide. Make sure My Business Account is set up for the corporation so you can see instalment reminders and pay online.

Frequently asked questions

Within six months after the tax year-end. If the year ends on the last day of a month, the return is due on the last day of the sixth month after — so a 31 December year-end files by 30 June. Tax owing is due much earlier: two months after year-end, or three months after year-end for a qualifying Canadian-controlled private corporation claiming the small business deduction.
