For most taxpayers, the first few months of the year can seem to involve a seemingly unending series of bills and payment deadlines. During January and February, many Canadians are still trying to pay off the bills from holiday spending. The first income tax instalment payment of 2025 is due on March 17, and the need to pay any tax balance for the 2024 tax year comes just six weeks after that, on April 30. Added to all of that, the deadline for making an RRSP contribution for 2024 falls on March 3, 2025.
