The marginal tax rate in Ontario is the rate of tax you pay on your next dollar of income. It's not the overall tax rate you pay on your entire income, but rather the rate applied to the *highest* portion of your earnings, within a specific tax bracket. This is a fundamental concept because it influences financial decisions related to investments, additional income, and tax planning strategies.
Ontario Tax Brackets and Rates for 2025
Ontario, like the federal government, uses a progressive tax system. This means that as your taxable income increases, you move into higher tax brackets, and each bracket has a different tax rate. It's crucial to understand that only the income within a specific bracket is taxed at that bracket's rate. The Ontario tax brackets for 2025, adjusted for indexation, are as follows:
The Ontario tax brackets and personal tax credit amounts are increased for 2025 by an indexation factor of 1.028 (2.8% increase), except for the $150,000 and $220,000 bracket amounts, which are not indexed for inflation.

| 2025 Taxable Income | 2025 Tax Rate |

It's important to note the indexation. The Federal and Ontario indexation factors, tax brackets and tax rates for 2025 have been confirmed to Canada Revenue Agency information.
Combined Federal and Ontario Marginal Tax Rates
To determine your total marginal tax rate, you must consider both the federal and Ontario rates. Since both taxes are levied on your income, they combine to create a higher overall marginal rate. The table below presents the combined federal and Ontario marginal tax rates for 2025, including surtaxes, and broken down by income type (other income, capital gains, eligible dividends, and non-eligible dividends):
| 2025 Taxable Income | Other Income | Capital Gains | Eligible Dividends | Non-Eligible Dividends |
|---|---|---|---|---|
| First $52,886 | 20.05% | 10.03% | -6.86% | 9.24% |
| Over $52,886 up to $57,375 | 24.15% | 12.08% | -1.20% | 13.95% |
| Over $57,375 up to $93,132 | 29.65% | 14.83% | 6.39% | 20.28% |
| Over $93,132 up to $105,775 | 31.48% | 15.74% | 8.92% | 22.38% |
| Over $105,775 up to $109,727 | 33.89% | 16.95% | 12.24% | 25.16% |
| Over $109,727 up to $114,750 | 37.91% | 18.95% | 17.79% | 29.78% |
| Over $114,750 up to $150,000 | 43.41% | 21.70% | 25.38% | 36.10% |
| Over $150,000 up to $177,882 | 44.97% | 22.48% | 27.53% | 37.90% |
| Over $177,882 up to $220,000 | 48.29% | 24.14% | 32.11% | 41.72% |
| Over $220,000 up to $253,414 | 49.85% | 24.92% | 34.26% | 43.51% |
| Over $253,414 | 53.53% | 26.76% | 39.34% | 47.74% |
Note: The marginal tax rate for dividends is a percentage of actual dividends received (not the grossed-up taxable amount). The marginal tax rate for capital gains is a percentage of total capital gains (not taxable capital gains). The gross-up rate for eligible dividends is 38%, and for non-eligible dividends is 15%. Surtaxes are calculated before deducting dividend tax credits.
Ontario Surtaxes: An Additional Layer
Ontario also applies surtaxes on top of its basic income tax. These surtaxes effectively increase the marginal tax rate for higher-income earners. For 2025, the surtax rates are:
- 20% surtax on Ontario tax exceeding $5,710.
- An additional 36% surtax (for a total of 56%) on Ontario tax exceeding $7,307.
For a person with only the basic personal amount, the surtax starts to apply at a taxable income of $93,132.
- The surtax increases the 13.16% tax rate to 20.53% (13.16% x 1.56).
- Surtaxes are calculated before deducting dividend tax credits.
Impact of the Ontario Health Premium
It is critical to remember the Ontario Health Premium, which is not included in the marginal tax rates listed above. The Health Premium can increase the marginal tax rates displayed by up to 25%. This premium is a separate charge and adds another layer of complexity to calculating your overall tax liability.
The Basic Personal Amount
Both the federal and Ontario governments offer a basic personal amount, which is a non-refundable tax credit that reduces the amount of tax you owe. For 2025, the Ontario basic personal amount is $12,747, taxed at a rate of 5.05%. The federal basic personal amount ranges from $14,538 to $16,129, taxed at 15%. This enhanced federal personal amount can affect marginal tax rates for incomes within the second-highest federal tax bracket.
Capital Gains Tax in Ontario
Capital gains, the profit from the sale of assets like stocks or real estate, are taxed differently than regular income. In Ontario, only 50% of your capital gains are included in your taxable income. This inclusion rate is then taxed at your marginal tax rate.
The reference text mentions a possible change to the Capital Gains Inclusion Rate at the federal level, though this change had not been reintroduced at the time of the referenced materials. It is crucial to stay informed about any updates regarding this inclusion rate, as it can significantly impact your tax liability.
Dividend Tax in Ontario
Dividends, which are distributions of a company's profits to its shareholders, are also taxed differently. There are two types: eligible and non-eligible dividends. The tax treatment differs for each, as reflected in the combined marginal tax rate table above. Ontario provides dividend tax credits to help offset the tax on dividends, and these credits are factored into the marginal rates.
Practical Implications of the Marginal Tax Rate
Understanding your marginal tax rate is essential for several reasons:
- Investment Decisions: Knowing your marginal tax rate helps you evaluate the after-tax return on different investments. For example, if you're in a high tax bracket, investments that generate capital gains (taxed at a lower rate) might be more attractive than those generating interest income (taxed at your full marginal rate).
- RRSP Contributions: Contributions to a Registered Retirement Savings Plan (RRSP) are tax-deductible, meaning they reduce your taxable income. The higher your marginal tax rate, the greater the tax savings you'll realize from an RRSP contribution.
- Additional Income: If you're considering taking on a side hustle or freelance work, your marginal tax rate will tell you how much of that extra income will be taxed.
- Tax Planning: Understanding your marginal tax rate allows you to strategize and potentially minimize your overall tax burden through legal means, such as income splitting or utilizing tax credits and deductions effectively.
Frequently Asked Questions
While detailed answers to all tax-related questions are beyond the scope of this article, some frequently asked questions regarding Ontario taxes, such as popular tax credits, the carbon tax rebate, and tax return filing, are mentioned in the reference text. It's recommended to consult the official Canada Revenue Agency (CRA) website or a qualified tax professional for detailed answers.
Conclusion
The marginal tax rate in Ontario is a critical concept for all taxpayers. It's not just a number; it's a key factor in financial planning, investment decisions, and overall tax compliance. By understanding how the progressive tax system, surtaxes, the Health Premium, and different income types are taxed, you can make informed decisions and potentially minimize your tax liability. Remember that tax laws and regulations can change, so staying informed and seeking professional advice when needed is always recommended.
