If your foreign corporation has any form of Canadian business activity, providing services in Canada, selling goods through Canadian agents, maintaining a project here, or disposing of Canadian property, there is a meaningful chance it has a Canadian tax return filing obligation. And that obligation may exist regardless of whether your corporation owes a single dollar of Canadian tax.
This is the third post in our series on Canadian tax for foreign corporations. If you haven’t read the earlier two, we’d recommend starting with Do Foreign Companies Need to File Taxes in Canada? for an accessible overview, and then Canadian Tax Obligations for Non-Resident Corporations for a broader look at the full range of obligations beyond the T2.
This post focuses specifically on the T2 return itself, who needs to file it, what goes with it, when it’s due, and what happens when it’s missed.
Who Must File a T2 Return
The T2 Corporation Income Tax Return is Canada’s federal corporate tax return. For resident corporations, filing is required annually regardless of whether any income was earned. For non-resident corporations, the obligation is more targeted, but it applies more broadly than most foreign businesses assume.
A non-resident corporation must file a T2 return with the CRA if the corporation carried on business in Canada or disposed of a taxable Canadian property at any time in the tax year. This requirement applies even if any profit(s) or gain(s) realized are claimed by the corporation to be exempt from Canadian tax due to the provisions of a tax treaty.
Beyond the core triggers, a non-resident corporation must also file a T2 when it has filed Form NR6 to pay Part I tax on net rental income or timber royalty income under subsection 216(4), or when it has filed Form T1288 to pay Part I tax on net income from acting services in a Canadian film or video production.
Additionally, any corporation that has had Regulation 105 withholding tax applied to payments it received for services in Canada must file a T2 to either pay any remaining Canadian tax balance or recover any overpaid amounts.
The critical takeaway: the T2 filing obligation and the Canadian tax obligation are separate things. You can owe no Canadian tax and still be required to file. Skipping the filing because you believe you owe nothing is one of the most common and costly mistakes non-resident corporations make.
Why Having a Treaty Doesn’t Exempt You From Filing
Canada has tax treaties with over 90 countries. Those treaties frequently reduce or eliminate Canadian tax on non-resident business income, but they do not eliminate the obligation to file a Canadian tax return.
This is where many non-resident corporations go wrong. The logic seems intuitive: if the treaty says Canada can’t tax our income, why would we need to file a Canadian return? The answer is that the treaty benefit isn’t automatic. It has to be formally claimed, on the right form, attached to a filed return, and submitted to the CRA on time.
All foreign corporations that carry on business in Canada are taxable in Canada on their income from the Canadian business. Generally, where Canada has a tax treaty with the foreign jurisdiction, the foreign corporation is not taxable in Canada unless it operates a permanent establishment in Canada. Foreign corporations wishing to claim the treaty benefit with Canada must file a Canadian corporate tax return with accurate and complete Schedules 91 and 97 within six months of the corporation’s year-end.
The consequence of not filing isn’t that the treaty protection disappears permanently; it’s that the exemption goes unclaimed, and penalties for the filing failure accumulate in the meantime. The CRA will not proactively apply treaty protection on your behalf.
Claiming Your Treaty Exemption Correctly
Schedule 91 (Information Concerning Claims for Treaty-Based Exemptions) is the CRA form through which non-resident corporations formally claim that their Canadian business income is exempt from Part I tax under an applicable tax treaty.
The schedule requires detailed information about the corporation’s Canadian activities, including the nature and location of services provided, the number of days employees were present in Canada, revenues earned, and the basis for the claimed treaty exemption. It also asks for the number and dollar amounts paid to both resident and non-resident subcontractors, and the number of resident and non-resident employees and their wages.
This last point is worth understanding clearly. The CRA is using Schedule 91 as a screening tool to ensure that timely, accurate, and complete T4A and T4A-NR (and related summaries) are filed. The schedule effectively allows the CRA to cross-reference your reported subcontractor payments and employee counts against the information slips it expects to receive. A non-resident corporation that files Schedule 91 but hasn’t filed the associated T4, T4A, or T4A-NR slips is likely to receive a follow-up from the CRA.
Schedule 91 must be attached to the T2 return. Filing the T2 without it, or filing it with incomplete information, can invalidate the treaty exemption claim and expose the corporation to penalties.
The Non-Resident Information Return
Schedule 97 (Additional Information on Non-Resident Corporations in Canada) is a mandatory attachment for all non-resident corporations filing a T2 return. Schedule 97 has been developed for all non-resident corporations that must file a tax return in Canada to identify the type of income they earned in Canada.
The schedule captures information about the corporation’s Canadian corporate structure, the nature of its Canadian income, its tax residency status, and whether it is claiming a treaty-based exemption, operating through a Canadian branch, or filing under specific election provisions such as Section 216 or Section 216.1.
Non-resident corporations are categorized on Schedule 97 according to their situation: treaty-exempt corporation, Canadian branch, Section 216 filer, emigrant corporation, and others. Each category carries different T2 obligations, and completing Schedule 97 accurately is essential to ensuring the return is processed correctly by the CRA.
Both Schedule 91 (where applicable) and Schedule 97 must be attached to the T2. Missing either one is not treated as a minor oversight.
What Else Goes With the T2
Depending on the nature of the non-resident corporation’s Canadian activities, additional schedules and information returns may be required in addition to the T2.
Schedule 20 (Part XIV, Additional Tax on Non-Resident Corporations) is required for corporations operating through a Canadian branch and subject to branch tax. Schedule 125 (Income Statement Information) and the General Index of Financial Information (GIFI) are required to report the corporation’s financial results.
Non-resident corporations that have made payments to non-resident subcontractors for services performed in Canada must file T4A-NR slips and a T4A-NR Summary. Those with resident or non-resident employees in Canada must file T4 slips and a T4 Summary. These information return obligations exist independently of the T2 filing obligation and carry their own separate deadlines and penalties.
Form T106 (Information Return of Non-Arm’s Length Transactions With Non-Residents) may also be required where the corporation has engaged in non-arm’s length transactions with related non-resident parties above the applicable threshold. Transfer pricing documentation requirements also apply to those transactions.
Filing in Canadian Dollars
Non-resident corporations filing a T2 return must report all financial information in Canadian dollars. Unlike resident corporations, which can, in certain circumstances, elect to report in a functional currency, non-resident corporations must file their T2 return, schedules, and the General Index of Financial Information in Canadian funds only. They are not eligible to file in a functional currency per section 261.
This requires non-resident corporations to convert all relevant financial figures to Canadian dollars using appropriate exchange rates. The CRA’s prescribed exchange rates or Bank of Canada average annual rates are typically used for this purpose. Getting the currency conversion wrong is a common source of errors in non-resident T2 returns.
Where and How to File
Non-resident corporations have to mail their returns to the Sudbury Tax Centre. Certain non-resident corporations can file electronically through Corporation Internet Filing and do not have to mail their returns to the Sudbury Tax Centre.
For resident corporations, electronic filing of the T2 has been mandatory since January 1, 2024 (with limited exceptions). Non-resident corporations are not subject to the mandatory e-filing requirement; paper filing to the Sudbury Tax Centre remains an option. However, electronic filing is available and generally results in faster processing and confirmation of receipt, which is advantageous given the importance of the filing deadline.
If filing electronically, the non-resident corporation must use CRA-certified software and hold a Web Access Code or EFILE number. Payments of $10,000 or more must be made electronically as of January 1, 2024, regardless of how the return itself is filed.
The Deadline
The T2 return must be filed within six months of the end of the corporation’s tax year. A corporation’s tax year is its fiscal period, which cannot exceed 53 weeks.
For a corporation with a December 31 fiscal year-end, the T2 is due June 30 of the following year. For a corporation with a March 31 fiscal year-end, the deadline is September 30. The six-month window is the same for non-resident corporations as it is for Canadian resident corporations.
Any tax balance owing is generally due within two months of the fiscal year-end, or three months for eligible Canadian-controlled private corporations, regardless of when the return itself is due. Interest on unpaid balances accrues after the payment due date, not after the filing due date. Non-resident corporations claiming a treaty exemption and owing no tax still face the six-month filing deadline, even though no payment is required.
Penalties for Late or Non-Filing
The penalty structure for non-resident corporations that fail to file on time depends on whether they owe tax.
Where tax is outstanding, the basic late-filing penalty is 5% of the unpaid balance, plus 1% for each complete month the return remains outstanding, up to a maximum of 12 months. Where a prior late-filing penalty was assessed in any of the three preceding years, and the CRA issued a demand to file, the penalty doubles to 10% plus 2% per month.
For non-resident corporations that owe no tax, for example, because a treaty exemption applies, a different penalty structure applies. The penalty is the greater of $100 and $25 per day for each day the failure to file continues, up to a maximum of 100 days. That is a maximum penalty of $2,500 for the filing failure alone, even where zero tax is owed.
Penalties for late or missing T4A-NR, T4, and T4A information slips are assessed separately and can add materially to the total penalty exposure. Interest on any assessed amounts compounds daily from the payment due date. A history of non-filing can also result in the CRA denying future Regulation 102 and 105 waiver applications, which compounds the cost of non-compliance across multiple compliance streams.
Voluntary Filing
A non-resident corporation that is not technically required to file a T2 may nonetheless benefit from doing so voluntarily.
The most common situation is where Regulation 105 withholding has been applied to payments the corporation received for services performed in Canada. The 15% withheld is not a final tax; it is a prepayment on account of whatever Canadian tax liability the corporation ultimately has.
Filing a T2 return is the only way to recover any overpayment. A non-resident corporation with a full treaty exemption from Canadian tax and $50,000 in Regulation 105 withholding sitting with the CRA has a significant incentive to file, even if it isn’t technically required to do so.
There is a time limit on this recovery. Regulation 105 withholdings are generally not refundable if the T2 return is filed more than three years after the relevant filing deadline. Voluntary filing is also relevant where the non-resident corporation has overpaid Part XIII withholding tax on passive income and wants to recover the excess through a treaty rate reduction claim.
The Bottom Line
The T2 filing requirement for non-resident corporations is broader, more consequential, and more interconnected with other compliance obligations than it appears on the surface. The return is the mechanism through which treaty exemptions are claimed, Regulation 105 withholdings are recovered, and branch tax is calculated and reported.
Missing it or filing it without the correct schedules can cost significantly more than the filing itself.

Frequently Asked Questions
- Does a non-resident corporation need to file a T2 even if it has a tax treaty with Canada?
Having a tax treaty does not eliminate the obligation to file a T2. If your non-resident corporation carried on business in Canada or disposed of taxable Canadian property, you are required to file a T2 return, and you must attach Schedule 91 and Schedule 97 to formally claim any treaty-based exemption. The treaty reduces or eliminates your Canadian tax liability; it does not waive the requirement to file.
- What is the difference between Schedule 91 and Schedule 97?
Schedule 91 is the treaty-based exemption claim form. It must be attached to the T2 return when the non-resident corporation is claiming that its Canadian business income is exempt from Part I tax under an applicable tax treaty. Schedule 97 is a mandatory information return for all non-resident corporations filing a T2; regardless of whether a treaty exemption is being claimed, it identifies the type of income earned and the corporation’s status as a non-resident filer. Both schedules must be filed, and both must be accurate and complete.
- Where does a non-resident corporation send its T2 return?
Non-resident corporations mail their T2 returns to the Sudbury Tax Centre in Ontario. Electronic filing is available through CRA-certified software using a Web Access Code or EFILE number, and is generally recommended for faster confirmation and processing. Unlike resident corporations, for which electronic filing is now mandatory, non-resident corporations can still file by paper.
- What currency must a non-resident corporation use when filing its T2 return in Canada?
All financial information on the T2 return, including income, expenses, and the General Index of Financial Information, must be reported in Canadian dollars. Non-resident corporations are not eligible to use functional currency reporting under section 261 of the Income Tax Act, which is available to resident corporations in certain circumstances. Currency conversion must be done using appropriate exchange rates before the return is filed.
- Can a non-resident corporation recover Regulation 105 withholding by filing a T2?
Yes, and this is one of the most important reasons for non-resident corporations to file voluntarily even when not technically required to. Regulation 105 withholding is a prepayment on account of Canadian tax liability, not a final tax. If the corporation’s actual Canadian tax liability is lower than the amount withheld, or zero due to a treaty exemption, filing a T2 return is the mechanism to recover the overpayment. The refund claim must generally be made within three years of the relevant filing deadline.
- What penalties apply if a non-resident corporation misses the T2 filing deadline?
If tax is owed, the penalty is 5% of the unpaid balance plus 1% per month for up to 12 months. If no tax is owed but a filing was still required, such as when a treaty exemption applies, the penalty is the greater of $100 or $25 per day for up to 100 days, for a maximum of $2,500. Separate penalties apply for missing associated information returns, such as T4A-NR and T4 slips. Interest on any assessed amounts accrues daily from the payment due date.
- Is there a situation where a non-resident corporation should file a T2 even if it doesn’t have to?
Voluntary filing makes sense when the corporation has had Regulation 105 withholding tax applied to service payments and wants to recover the overpayment, when Part XIII tax was withheld at a higher rate than the applicable treaty rate and a refund is available, or when certain tax elections need to be formally made. In all cases, voluntary filing is time-sensitive; withholding tax refunds are generally not available if the return is filed more than three years after the relevant deadline.
