Late-filing penalty
For most information returns, if you file your information return late, or if you distribute slips to the employees or income recipients late, you are liable for each failure to a penalty of $25 per day, from a minimum of $100 to a maximum of $2,500.
Failure to file information returns in electronic format
If you file more than 500 various information slips (for example T4, T4A, T5) and you do not file the information returns in an electronic format as required under the Income Tax Act and Income Tax Regulations, you are liable to a penalty of $2,500 for the first offence. For each subsequent occurrence, the penalty will increase by increments of $2,500.
If a service bureau is filing an information return for you, you are still responsible for the accuracy of the information and for any balance owing.
