The RRSP contribution deadline for the 2024 tax year is fast approaching. The deadline for RRSP contributions that can be applied to your 2024 taxes is March 3, 2025. RRSP contributions are tax-deductible, which means they can be used to reduce your taxable income and may even result in a tax refund. In addition, the money in your RRSP can grow tax-deferred as long as the money remains within the RRSP.
