Our tax system is, for the most part, a mystery to individual Canadians. The rules surrounding income tax are complicated and it can seem that for every rule there is an equal number of exceptions or qualifications. There is, however, one rule which applies to every individual taxpayer in Canada, regardless of location, income, or circumstances, and of which most Canadians are aware. That rule is that income tax owed for a year must be paid, in full, on or before April 30 of the following year. This year, that means that individual income taxes owed for 2018 must be remitted to the Canada Revenue Agency (CRA) on or before Tuesday, April 30, 2019 — no exceptions and, absent extraordinary circumstances, no extensions.
