Understanding how taxes are calculated is essential for average people and businesses when planning their finances. One important concept that often arises in tax discussions is the marginal tax rate. By learning about this concept, taxpayers can better anticipate their tax obligations and make more informed financial decisions.
A marginal tax rate is the percentage of tax applied to an individual or entity’s next dollar of income. This means that income is taxed at different rates, falling into brackets. For example, if you move into a higher tax bracket, the additional income level earned within that bracket is taxed at a higher rate, but the income in the lower brackets remains taxed at their respective rates.
Are Marginal Tax Rates Beneficial?
Progressivity
Marginal tax rates are inherently progressive, which means they tax higher earners at a higher rate. This helps reduce income inequality by ensuring that those with the financial capacity contribute more to the public finances. It provides a structured way to redistribute wealth and fund essential public services like healthcare, education and infrastructure.
Incentivizes Earning
While taxing higher earnings at higher rates, marginal tax rates also encourage taxpayers to earn more. Since each dollar of income is taxed incrementally rather than as a whole, individuals can be confident their overall tax burden will not excessively punish extra earnings. This pushes people to work harder, innovate and invest in personal development, knowing that only their additional income will be taxed more.
Economic Stability
Marginal tax systems can contribute to economic stability by stabilizing consumption. During economic downturns, low-income earners who typically spend a larger proportion of their income benefit more from lower marginal rates, sustaining demand for goods and services. Conversely, in periods of economic growth, higher taxes on additional income can prevent the economy from overheating by reducing the disposable income of high earners.
Simplicity and Fairness
Marginal tax rates give a straightforward and fair method of taxation. A single taxpayer can easily understand that as their entire income increases, their tax rate on extra income also increases. This transparency aids in tax compliance and helps avoid pitfalls related to avoidance or evasion. Additionally, it provides a clearer framework for policy deliberation as each bracket and corresponding rate can be adjusted according to the economic demands and societal goals.
Encourages Investment in Tax-Advantaged Accounts
Marginal tax rates encourage people to invest in tax-advantaged accounts, such as Registered Retirement Savings Plans (RRSPs) and Tax-Free Savings Accounts (TFSAs) in Canada. These accounts offer tax benefits that align well with the structure of marginal tax rates. For example, contributions to an RRSP are tax-deductible, reducing the contributor’s taxable income and lowering the immediate tax burden according to their marginal tax rate.
On the other hand, investments within a TFSA grow tax-free, and withdrawals are not subject to additional taxes, making it a flexible option for Canadians looking to avoid paying higher taxes on investment gains. This helps Canadians manage their taxable income, minimize taxes owed in high-income years and maximize their long-term savings and investment returns.
How to Calculate Your Marginal Tax Rate?
Determine Your Total Taxable Income
Calculate your total taxable income for the year. This includes employment income, self-employment income, investment income and other sources of taxable income minus allowable tax deductions such as RRSP contributions and certain expenses.
Identify Federal Tax Brackets
Canada’s federal tax system is progressive, consisting of multiple tax brackets. For the tax year 2024, taken from Fidelity, these are:
- 15% up to $55,867 of taxable income
- 20.5% between $55,867 and $111,733
- 26% between $111,733 and $173,205
- 29% between $173,205 up to $246,752
- 33% on any taxable income exceeding $246,752
Identify Provincial/Territorial Tax Brackets
Each province and territory in Canada has its own tax brackets and rates. These rates are also progressive. You need to find the tax brackets relevant to your province or territory of residence. For instance, in Ontario for 2024, also taken from Fidelity, these are:
- 5.05% up to $51,446 of taxable income
- 9.15% between $51,446 and $102,894
- 11.16% between $102,894 and $150,000
- 12.16% between $150,000 and $220,000
- 13.16% on any taxable income exceeding $220,000
Combine Federal and Provincial/Territorial Rates
Add the provincial/territorial and federal taxes to determine your combined marginal tax rate.
Remember that this tax calculation is solely concerned with the marginal tax rate payable on the amount in question and makes no allowances for surtaxes, tax deductions or credits such as RRSP contributions, or other credits or deductions such as claims for medical expenses or dependents.

rates for the bracket corresponding to your income. One example is if your taxable income is $100,000:
- Federal rate for $100,000. 20.5%
- Ontario rate for $100,000. 9.15% (since $100,000 falls in the $51,446 to $102,894 range and partially in the next range)
- Combined marginal tax rate = 20.5% + 9.15% = 29.65%
Account for Additional Taxes and Credits
Factor in other taxes or surtaxes that may apply in specific provinces/territories. For example, Ontario has a surtax on higher incomes. Additionally, certain tax credits can reduce your marginal tax rate.
The Difference Between an Average Tax Rate and a Marginal Tax Rate
- Average Tax Rate. It is calculated by dividing the taxes paid by the taxable income. It provides a simple figure representing the overall percentage of income that goes towards taxes. For instance, if you paid $20,000 in taxes on $100,000 of income, your average tax rate would be 20%.
- Marginal Tax Rate. This is the rate at which your last dollar of income is taxed. This rate is determined by the income bracket your last dollar falls into, reflecting the percentage of tax applied to your next dollar of earnings. If you earn $100,000 and your next dollar falls into the 29.65% combined federal and Ontario tax bracket, your marginal tax rate would be 29.65%.
While the average tax rate gives an overall sense of the tax burden, the marginal tax rate is particularly important for making financial decisions, such as determining the tax impact of additional income or the benefits of deductions and credits. Understanding both rates can give a complete overview of your tax situation and help you make more informed financial choices.
