We prepare tax returns for private clients and small corporations in Ontario, Canada.
The usual deadline for filing personal tax returns is April 30th each year, although under certain circumstances it may be extended to June 15th. While it is not mandatory to file a tax return, it is highly recommended to avoid late filing fees and penalties if you owe taxes to the government.
Without filing a tax return you will NOT receive a GST/HST credit, even if you are eligible for it.
Corporations are also recommended to file a corporate tax return on time even if there are no taxes to pay. This will allow to claim business losses for future deductions. A deadline to file a corporate tax return (also called a T2) is 6 months after the fiscal year end of the corporations. However, if there are taxes owing, those should be paid within 3 months after the year end.
