T2 nil return: an inactive corporation still files every year

Which corporations have to file a T2 with no activity?

All of them, with three narrow exceptions. The CRA's T2 guide says every corporation, including nonprofit organizations, tax exempt corporations and inactive corporations, files a return for every tax year even if there is no tax payable canada.ca. The statute puts it the same way: paragraph 150(1)(a) requires a corporation's return within six months after the end of each taxation year, without notice or demand laws-lois.justice.gc.ca.

The guide's line 280 instructions remove any doubt: even if a corporation is inactive, meaning it has not operated during the tax year, it has to file a return canada.ca. The deadline is the usual one. A year ending on the last day of a month is due on the last day of the sixth month, so a March 31 year end files by September 30 canada.ca. Weekend and holiday shifts are on the T2 filing deadline page.

What does a late nil return actually cost?

The regular late filing penalty is 5% of the tax unpaid at the filing deadline plus 1% for each complete month late, up to 12 months laws-lois.justice.gc.ca. On zero unpaid tax that is zero. Three other penalties don't depend on unpaid tax, and they are the ones that catch dormant corporations.

The CRA's penalty page confirms the $10 million large corporation test (with related corporations) and the $100 floor plus $25 a day for corporations not resident in Canada canada.ca. The section 235 formula uses taxable capital, not unpaid tax, so a dormant holding company with large assets still pays it laws-lois.justice.gc.ca.

Worked example: a corporation not resident in Canada that has to file a T2 owes no tax and files 45 days late. The 162(1) amount is $0. The daily amount is $25 × 45 = $1,125, which beats the $100 floor, so the penalty is $1,125. At 100 days or more it stops at $25 × 100 = $2,500 laws-lois.justice.gc.ca. When a nonresident corporation has to file is a separate question.

There's also the demand. Subsection 150(2) lets the CRA demand a return from any person whether or not tax is payable laws-lois.justice.gc.ca, and a demand plus a penalty in any of the three previous years is what doubles the penalty on a later year that does owe tax. The full math is on the T2 late filing penalty page.

What goes on a nil T2?

A full T2 through certified software, in almost every case. For tax years starting after 2023, all corporations file electronically except insurance corporations, corporations not resident in Canada, corporations reporting in functional currency and corporations exempt under section 149 canada.ca. A required electronic return filed on paper costs $1,000 under subsection 162(7.2) laws-lois.justice.gc.ca. That includes the paper T2 Short for an inactive CCPC, as explained on the T2 Short Return page.

Answer yes to line 280, "Is the corporation inactive?" canada.ca. A corporation that was inactive throughout the year and has no balance sheet or income statement information to report doesn't have to attach Schedules 100, 125 and 141, though the CRA accepts them if filed canada.ca.

Read that exemption narrowly. It needs both parts: inactive all year, and nothing to report. A shell that still holds a bank balance, a shareholder loan or an investment has balance sheet figures, so the exemption doesn't fit and the GIFI schedules go in, with Schedule 141 completed even when there are no notes canada.ca. If it earned interest, it had income to report and wasn't inactive in the sense the GIFI exemption needs.

The page 2 questions still apply. A private corporation with a shareholder holding 10% or more of its common or preferred shares attaches Schedule 50, and any other yes answer brings in its schedule canada.ca.

Worked example: the refund a dormant corporation loses by not filing

Subsection 164(1) lets the CRA refund an overpayment only when the return is made within 3 years from the end of the year laws-lois.justice.gc.ca. The dividend refund under subsection 129(1) has the same 3 year condition laws-lois.justice.gc.ca. An inactive corporation is exactly the client who forgets this.

Your client has a December 31 year end. It stopped operating in early 2022 after paying $4,000 of instalments based on its 2021 tax, and its 2022 tax came to nil. Nobody filed for 2022 or later. Today is October 15, 2026.

None of the four late returns carries a 162(1) penalty, because no tax was unpaid. The cost is the $4,000, gone because the 3 year window for 2022 closed on December 31, 2025. If a corporation stops operating partway through a year, file that year promptly and stop the instalments.

If several years are missing and some of them did owe tax, look at the Voluntary Disclosures Program before you file them.

Do the provincial and GST/HST returns stop too?

Not automatically. An inactive corporation with a GST/HST account files a return for every reporting period even with no business transactions or income and no net tax to remit, which is a nil return, and it files a final return when the account closes canada.ca. Late GST/HST returns have their own rules, on the GST/HST late filing penalty page.

Alberta publishes a clear exemption for dormant companies. A corporation with a permanent establishment in Alberta files an AT1 unless it is exempt alberta.ca. Alberta's January 2025 checklist exempts a corporation that meets all of these: a CCPC throughout the year, no permanent establishment outside Alberta, no taxable income for the year (before a loss carried back from a later year), no refund of an overpayment for the year, gross revenue of $500,000 or less on its financial statements, a federal T2 filed, and the same discretionary balances (UCC, reserves, losses) for Alberta as federally alberta.ca. Claiming one of the listed Alberta credits, or the innovation employment grant, removes the exemption.

Notice the refund condition. An Alberta corporation in the position of the example above, with Alberta instalments paid for a year that ended with no tax, is entitled to a refund of an overpayment for that year, so the exemption fails for it alberta.ca.

When dissolving beats filing nil returns every year

Until the corporation is formally dissolved with its incorporating authority, the CRA considers it to still exist, and it has to file a return even if there is no tax payable canada.ca. A company that stopped operating years ago keeps its annual T2, GST/HST and provincial obligations for as long as it stays on the register.

If your client has no plan to restart, dissolution ends the cycle. The final T2 covers the year ending on the dissolution date and is due six months later; the timing is on the T2 deadline after dissolution page. After dissolution, check Form RC145 to see whether the CRA needs it to close the business number accounts, with a copy of the articles of dissolution canada.ca. The steps are on the RC145 page.
