Completing Your Income Tax Return
You are required to provide all pertinent information about your income, deductions and credits so that you can calculate and pay the income tax you owe. By doing so, you are contributing your fair share to the financing of public services, particularly in the areas of education, healthcare and social services. If you fail to provide the necessary information, or provide inaccurate or incomplete information, you are liable to penalties; penal proceedings may also be brought against you.
If you fail to report income, and have already failed to report income of the same type in any of the three previous years, you are liable to a penalty calculated on the unreported income. You can make a voluntary disclosure in order to rectify your tax situation.
