Business Tax Deadlines in Canada, Every CRA Date You Need to Know
Missing a business tax deadline costs you money. Here is every deadline Canadian business owners need to track.
Running a business in Canada means managing multiple CRA filing obligations simultaneously, each with its own deadline, its own penalty structure, and its own consequences for missing the date. This page covers every key business tax deadline so you know exactly what is due, when, and what happens if you are late.

When Is the Corporate Tax Return (T2) Due in Canada?
Your T2 corporate return is due six months after the end of your corporation's fiscal year. Your tax balance owing, however, is due two months after your fiscal year end, or three months if you are a qualifying Canadian Controlled Private Corporation.
The payment deadline is always earlier than the filing deadline. Daily compound interest starts accruing the day after your payment deadline. For example, if your fiscal year ends December 31, your tax is due February 28, but your return is due June 30.
What Happens If You File Your T2 Late?

The CRA charges a 5 percent penalty on your unpaid balance plus 1 percent per month for up to 12 months. If you had a previous late filing, the penalty doubles to 10 percent plus 2 percent per month.
Even if you owe zero tax, a minimum flat $1,000 penalty still applies for filing late. Dormant corporations are not exempt from this rule. Our accountants and our tax software ensure your corporate return is filed correctly and on time.
A Canadian corporation that misses its T2 filing deadline, even with zero tax owing, faces a minimum $1,000 CRA penalty. The deadline applies to every corporation every year.
What Are the GST/HST Filing Deadlines for Businesses?

For annual filers under $1.5 million in revenue, returns are due 3 months after your fiscal year end. For quarterly filers between $1.5 million and $6 million, returns are due 1 month after the quarter end. Monthly filers over $6 million must file 1 month after the month end.
The late penalty is 1 percent of the balance plus 0.25 percent per month up to 12 months. Our accountants and our tax software manage your GST/HST filing alongside your other returns.
