Marginal Tax Rate Alberta 2026: A Comprehensive Guide

The marginal tax rate in Alberta for 2025 refers to the rate of tax you pay on each additional dollar of income you earn. Alberta, like the rest of Canada, employs a progressive tax system, meaning the tax rate increases as income rises through defined tax brackets. Crucially, the marginal tax rate is not the overall tax rate you pay on your entire income; it's only the rate on the portion of your income that falls within a specific bracket.

Alberta's Tax Brackets and Rates for 2025

Alberta's tax system, along with the federal tax system, uses indexation to adjust tax brackets and personal tax credit amounts. For 2025, Alberta's indexation factor is 1.02 (a 2% increase), as established by Bill 32, Financial Statutes Amendment Act, 2026 (No. 2). This bill dictates that future indexation will be the lesser of 2% or the change in the Alberta Consumer Price Index. The Federal indexation is 2.7%.

It's important to note that these are the provincial rates. Albertans also pay federal income tax, which has its own set of brackets and rates.

Combined Federal and Alberta Marginal Tax Rates for 2025

To fully understand your tax liability, you need to consider both the federal and provincial marginal tax rates. The following table presents the combined marginal tax rates for Alberta residents in 2025, categorized by different types of income:

The percentages for capital gains represent the tax on the total capital gain (not just the taxable portion). The percentages for dividends represent the tax on the actual dividend amount received (not the grossed-up amount). Remember that eligible dividends have a gross-up rate of 38%, while non-eligible dividends have a gross-up rate of 15%.

Understanding the Different Income Types

The table above differentiates between several types of income, each taxed differently:

• Other Income: This includes most common forms of income, such as employment income, self-employment income, interest, and rental income.
• Capital Gains: This refers to the profit realized from the sale of a capital asset, such as stocks or real estate. Only 50% of capital gains are taxable in Canada.
• Eligible Canadian Dividends: These are dividends paid by public Canadian corporations and certain private corporations. They receive preferential tax treatment due to the dividend tax credit.
• Non-Eligible Canadian Dividends: These are typically dividends from smaller, private Canadian corporations. They receive a smaller dividend tax credit than eligible dividends.

Alberta's Basic Personal Amount (BPA) for 2025

Alberta boasts one of the highest Basic Personal Amounts (BPA) in Canada. The BPA is a non-refundable tax credit that all individuals can claim. It represents the amount of income you can earn before you start paying income tax. For 2025, the Alberta BPA is $22,323, taxed at a rate of 10%. The federal BPA for 2025 ranges from $14,538 to $16,129, taxed at 15%.

The Impact of Indexation

Indexation plays a significant role in shaping the tax landscape. Both the federal and Alberta governments use indexation to adjust tax brackets and personal amounts annually to account for inflation. This prevents "bracket creep," where inflation pushes individuals into higher tax brackets even if their real income hasn't increased.

Provincial Tax Credits Specific to Alberta

Alberta offers several provincial tax credits, complementing federal credits. A notable example is the Alberta Child and Family Benefit (ACFB), a non-taxable benefit for lower-income families with children under 18. This benefit combines the former Alberta Family Employment Tax Credit (AFETC) and the Alberta Child Benefit (ACB). Payments are made quarterly.

Why Alberta's Tax System is Considered Favorable

Alberta's tax system is often perceived as favorable due to several factors. Besides the high BPA, the lowest tax bracket (up to $151,234 for 2025) is taxed at a relatively low rate of 10%. The absence of a provincial sales tax, payroll tax, or health premiums further contributes to a lower overall tax burden for many Albertans compared to residents of other provinces.

Calculating Your Taxable Income

To determine which tax bracket you fall into, you need to calculate your taxable income. This involves summing all sources of income (employment, self-employment, pensions, investments, etc.) and then subtracting applicable deductions (RRSP contributions, union dues, etc.). The resulting figure is your taxable income, which is used to determine your marginal tax rates.

Conclusion

The marginal tax rate in Alberta for 2025 is a crucial element of the province's tax system. Understanding how these rates work, along with the combined federal and provincial rates, is essential for accurate tax planning.

Alberta's relatively low tax rates, high basic personal amount, and lack of certain taxes make it an attractive province from a tax perspective. However, it's important to stay informed about changes to tax laws and indexation factors, as these can impact your tax liability.
