Most Canadians know that the deadline for making contributions to one’s registered retirement savings plan (RRSP) comes 60 days after the end of the calendar year, around the end of February. There are, however, some circumstances in which an RRSP contribution must be (or should be) made by December 31 in order to achieve the desired tax result.
The Old Age Security (OAS) program is the only aspect of Canada’s retirement income system which does not require a direct contribution from recipients of program benefits. Rather, the OAS program is funded through general tax revenues, and eligibility to receive OAS is based solely on Canadian residency.
The Canadian tax system is a “self-assessing system” which relies heavily on the voluntary co-operation of taxpayers. Canadians are expected (in fact, in most cases, required) to complete and file a tax return each spring, reporting income from all sources, calculating the amount of tax owed, and remitting that amount to the federal government on or before April 30.
