A registered retirement savings plan (RRSP) is a type of tax-deferred account that allows individuals to save for retirement. Contributions to an RRSP are deductible from taxable income, which means that they reduce the amount of income tax payable for the year. The amount of tax savings from an RRSP contribution depends on the individual’s marginal tax rate, which is the tax rate applied to the next dollar earned. Leira has a marginal tax rate of 45% and may deduct $5,000 in RRSP contributions on her income tax return. If she decides to use her available deduction and assuming this does not reduce her taxable income to a lower tax bracket, by how much will it reduce her tax payable? To answer this question, we can use the following formula: $$(Tax savings = RRSP contribution \times Marginal tax rate)
