A section 166.1 extension of time application is often granted by the CRA. However, section 166.2 extension of time applications are granted in relatively exceptional circumstances by the Tax Court of Canada. Therefore, in order to avoid losing your tax appeal rights and your ability to fight CRA collection officers, it is important to have your expert Canadian tax litigation lawyer file the notice of objection within the time limit whenever possible. There are cases in which extension of time applications have been denied where some of the aforementioned preconditions of the applications have not been met by the taxpayer. Therefore, if you have received a notice of tax assessment or reassessment that you do not agree with, contact one of our experienced Toronto tax lawyers to discuss your best options to object to the tax assessment.
