T2 Corporate Tax Return: Deadlines and What to Prepare 

Every corporation in Canada has its own tax return, separate from the owner’s personal return. It’s called the T2. Many new business owners are surprised by two things: the corporation must file even if it owes no tax, and the deadline to pay comes earlier than the deadline to file. 

The short answer: every resident corporation must file a T2 for each tax year, generally within six months of its year-end. Any tax owing is usually due two months after year-end, or three months for some Canadian-controlled private corporations (CCPCs) that meet CRA conditions. Late filing can trigger a penalty of 5% of unpaid tax plus 1% per month, up to 12 months. 

Who has to file a T2? 

According to the CRA, every resident corporation must file a T2 return for every tax year, even if no tax is payable. That includes: 

• Small and inactive corporations 

• Holding companies 

• Non-profit organisations and tax-exempt corporations (with some exceptions) 

The CRA lists only limited exceptions, such as tax-exempt Crown corporations, Hutterite colonies and registered charities. 

When is the T2 due? 

The CRA’s rule: file within six months of the end of each tax year. 

If the deadline falls on a Saturday, Sunday or CRA-recognised public holiday, the return is on time if the CRA receives it, or it’s postmarked, by the next business day. 

When must the tax be paid? 

This is the deadline people most often miss. 

• Generally: two months after the end of the tax year. 

• Three months after year-end for a corporation that, according to the CRA: 

• is a CCPC throughout the tax year, 

• claimed the small business deduction in the current or previous tax year, and 

• meets the CRA’s taxable income test for the previous year (its taxable income, or combined taxable income for associated corporations, did not exceed its business limit). 

Example: a CCPC with a 31 December 2026 year-end that meets the conditions has until 31 March 2027 to pay, but until 30 June 2027 to file. Interest applies to unpaid amounts after the balance-due day. 

Instalments 

Many corporations must also pay tax in instalments during the year, monthly or quarterly depending on their circumstances. See Tax Instalments in Canada. 

How is the T2 filed? 

For tax years starting after 2023, the CRA requires all corporations to file electronically, except insurance corporations, non-resident corporations, corporations reporting in functional currency and corporations exempt from tax under section 149. The CRA can charge a $1,000 penalty if a corporation required to file electronically doesn’t. 

Some small corporations may be eligible for the shorter T2 Short Return. Eligibility is set out in the CRA’s T2 guide (T4012). 

What happens if you file late? 

According to the CRA, the late-filing penalty is 5% of the unpaid tax at the filing deadline, plus 1% of that amount for each full month the return is late, up to 12 months. A larger repeat penalty can apply if the CRA has already issued a demand to file and assessed a failure-to-file penalty in any of the three previous tax years. 

If no tax is owing, the percentage penalty works out to nil, but filing late can still cause problems, such as delayed refunds and difficulty with financing or CRA compliance. 

What your accountant needs to prepare the T2 

If your bookkeeping isn’t up to date, start there. See catch-up bookkeeping and our bookkeeping services. 

Financial statements 

Your T2 includes financial information about the corporation. Many small corporations have their accountant prepare year-end financial statements as part of the process. See Year-End Financial Statements and Compilation Engagements Explained.
