Do I need to charge GST/HST as a contractor or small business?

Once your taxable revenue passes $30,000 over four consecutive quarters you must register for GST/HST and charge it. Many businesses register earlier to claim input tax credits. We handle registration and filing for you.

What is the difference between GST, HST and PST?

GST is the 5% federal tax. In HST provinces (Ontario and the Atlantic provinces) the federal and provincial portions are combined into one tax. BC, Saskatchewan, Manitoba and Quebec keep a separate provincial sales tax (PST, RST or QST) on top of the 5% GST.

T2 deadlines

T2 deadline calculator

Your corporation has two different deadlines and most owners mix them up. Enter your fiscal year-end to see both.

Fiscal year-end Is this a CCPC claiming the small business deduction?

Why there are two dates

A Canadian corporation files its T2 return six months after its fiscal year-end, but the tax owing is due earlier — three months after year-end for a Canadian-controlled private corporation claiming the small business deduction, two months for everyone else. That gap is where most late-payment interest comes from: the owner waits for the filing deadline, not realising the money was due months before.

Interest runs from the day after the balance-due date at the CRA's prescribed rate, compounded daily, and it is not deductible. The late-filing penalty is separate again — 5% of the balance plus 1% per month, up to 12 months, doubling for repeat late filing. Full breakdown of the penalties →

Choosing a year-end changes these dates

A new corporation can pick almost any fiscal year-end within 53 weeks of incorporating, and that single choice sets every date above for the life of the company. A non-December year-end also moves your work outside your accountant's busiest season. How to choose your year-end →

Dates that land on a weekend or a public holiday move to the next business day. If you would rather not track any of this, we handle the T2 and the calendar as part of a fixed annual fee.

Common questions

T2 Deadline Calculator FAQ

When is my T2 corporate tax return due?+

Six months after your corporation’s fiscal year-end. If your year-end is December 31, the T2 is due June 30 of the following year.

When is corporate tax actually payable?+

Earlier than the filing deadline. A Canadian-controlled private corporation claiming the small business deduction generally has three months after year-end to pay; other corporations have two months. Interest runs from the day after that date.

What happens if I file the T2 late?+

The late-filing penalty is 5% of the unpaid balance plus 1% for each complete month the return is late, up to 12 months. For a repeat late filer it doubles to 10% plus 2% per month. That is on top of interest on the unpaid tax.

Do I have to pay instalments too?+

Generally yes if your net federal tax owing exceeded $3,000 in the current year or in either of the two preceding years. Most corporations pay monthly; an eligible small CCPC with a clean compliance history may qualify for quarterly. A brand-new corporation is exempt in its first tax year.
