Combined Federal and Quebec Marginal Tax Rates

When calculating your overall tax liability, you must consider both federal and Quebec taxes. The marginal tax rates combine to create a higher overall rate. Quebec residents receive a federal tax abatement of 16.5% of federal tax. However, this abatement is applied *after* deducting the basic personal amount from the net federal tax. Therefore, the federal personal amount tax credit is also reduced by 16.5%.

Here's a table showing the combined federal and Quebec marginal tax rates for 2025, considering different income types:

Note: The marginal tax rate for dividends is a percentage of the *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%.

Understanding the Impact of the Marginal Tax Rate

The marginal tax rate is crucial for financial planning. It helps you understand the tax implications of earning additional income, whether through salary increases, investments, or other sources. For example, if you're considering taking on extra work, knowing your marginal tax rate allows you to estimate the actual after-tax income you'll receive.

Example

Let say your taxable income is 100,000$, placing you in the 19% tax bracket. If you were to earn a bonus of 10,000$, you need to calculate the portion that will fall into the 19% tax bracket, and the portion in the 24% tax bracket.

First, we need to know the limit of the 19% tax bracket, which is 106,495$. The amount in that bracket is 106,495$ - 100,000$ = 6,495$. The income tax on this part of your income will be: 6,495$ * 0.19 = 1234.05$.

Next, the rest of your bonus will fall into the 24% tax bracket, meaning: 10,000$ - 6,495$ = 3505$. The income tax on this part of your income will be: 3,505$ * 0.24 = 841.2$.

The total income tax on your bonus will be 1234.05$ + 841.2$ = 2075.25$

Quebec Basic Personal Amount

The Quebec basic personal amount is a non-refundable tax credit that all residents can claim. For 2025, the Quebec basic personal amount is $18,571, taxed at a rate of 14%. This is an increase from the 2026 amount of $18,056.

Federal Basic Personal Amount

The federal basic personal amount is also a non-refundable tax credit. For 2025, the minimum amount is $14,538 and the maximum is $16,129, all taxed at the rate of 15%.
