Understanding how much tax you owe in Canada starts with one foundational concept: the bracket system. Canada uses a progressive marginal tax rate, meaning each dollar you earn is taxed only at the rate assigned to the bracket it falls into — not at a flat rate applied to your entire income. This guide breaks down every federal and major provincial bracket for 2025, explains how indexation works, and shows you exactly what your effective rate looks like compared to your marginal rate.
The most common misconception Canadians have about taxes is that earning more automatically means paying more tax on everything they made. That is not how it works. If you move into a higher bracket, only the dollars above that threshold are taxed at the higher rate. The dollars below stay taxed at the lower rate. This distinction — marginal rate versus effective rate — matters enormously for financial planning.
To make this concrete: suppose you are an Alberta resident earning $75,000 in 2025. The first $57,375 of your federal income is taxed at 15%. The remaining $17,625 is taxed at 20.5%. Your marginal federal rate is 20.5%, but your actual average federal rate on the full $75,000 works out to closer to 16.6%. Add in provincial rates and the basic personal amount credit, and your overall effective combined rate will be noticeably lower than what most people assume when they hear "20.5% bracket."
The Canada Revenue Agency (CRA) applies the following federal brackets to all Canadian taxpayers in 2025:
Every Canadian taxpayer is also entitled to the federal Basic Personal Amount (BPA) of $16,129 for 2025. This non-refundable tax credit reduces your federal tax owing by $2,419 (calculated at the 15% rate). In practical terms, the first $16,129 you earn is effectively sheltered from federal income tax. Higher earners receive a slightly reduced BPA under the phaseout rules that apply above certain income thresholds.
Each year, the CRA adjusts federal brackets and the BPA for inflation using an indexation factor. For 2025, the federal indexation rate is approximately 2.7%. This adjustment prevents "bracket creep" — the phenomenon where inflation-driven wage increases push workers into higher brackets even though their real purchasing power has not increased. Provincial brackets are indexed separately, often at different rates.
Alberta has no provincial sales tax and maintains one of the most competitive personal income tax structures in the country. The 2025 Alberta brackets are:
Alberta's provincial Basic Personal Amount is $21,003 for 2025, the highest BPA in Canada. This generous threshold, combined with the flat 10% bottom rate that applies to the first $148,269, means Albertans at most income levels pay significantly less provincial tax than residents of other major provinces. The combined federal and Alberta top marginal rate for 2025 is 48%.
Ontario's provincial brackets for 2025 are:
Ontario also applies a surtax on higher provincial tax amounts, which can increase the effective provincial rate further for high earners. The combined federal and Ontario top marginal rate is 53.53%, among the highest in Canada.
BC uses a seven-bracket structure with rates ranging from 5.06% to 20.5% at the provincial level. The combined federal and BC top marginal rate sits at 53.5%, virtually identical to Ontario's. BC's lower brackets are modestly more competitive than Ontario's, but the top rate converges at similar levels for high-income earners.
For planning purposes, here are the combined federal plus provincial top marginal rates in key provinces for 2025:
If you are a business owner or incorporated professional, these rates apply to income you draw personally as salary or dividends. The structure of how you pay yourself can have a significant impact on how much of your income is exposed to these top rates.
One of the most powerful reasons many Canadian business owners incorporate is the difference between corporate and personal tax rates. A Canadian-Controlled Private Corporation (CCPC) pays just 11% in combined federal and Alberta provincial tax on active business income eligible for the Small Business Deduction — compared to 23% for general corporations not eligible for that deduction.
That gap between 11% and the top personal marginal rate of 48% (in Alberta) creates a significant tax deferral opportunity. By retaining earnings inside the corporation, a business owner defers the personal tax that would otherwise apply until funds are withdrawn. However, the integration rules, passive investment income thresholds, and dividend tax treatment all affect how much benefit is actually captured. This is where working with a qualified accountant becomes critical.
At Swift Accounting Calgary, we regularly help business owners model the optimal blend of salary and dividends based on current year brackets, RRSP room, and corporate retained earnings to minimize the overall tax burden across both the corporate and personal return.
Consider an Alberta resident with $120,000 of employment income in 2025. Here is how the federal tax calculation works before credits:
Subtract the BPA credit of $2,419 and federal tax owing drops to approximately $19,314. Add Alberta provincial tax (roughly $11,978 before the provincial BPA credit), and total tax is around $31,292 on $120,000 of income. That works out to an effective combined rate of approximately 26.1% — not the 26% to 32% marginal rate that applies to the top dollars of income. Your marginal rate tells you what tax you pay on the next dollar earned; your effective rate tells you what you actually paid overall.
Canadian tax law is layered, provincial rules vary significantly, and the interplay between brackets, credits, deductions, and corporate structures creates planning opportunities that are easy to miss without professional guidance. The 2025 indexation adjustments, the changes to the BPA phaseout for higher earners, and the ongoing legislative environment around capital gains all make this a year where a proactive conversation with your accountant can pay meaningful dividends.

The 2025 federal brackets are: 15% on the first $57,375; 20.5% on $57,375 to $114,750; 26% on $114,750 to $158,519; 29% on $158,519 to $246,752; and 33% on income above $246,752. The federal Basic Personal Amount of $16,129 generates a $2,419 non-refundable credit that reduces tax owing for most Canadians.
Alberta's combined federal and provincial top marginal rate of 48% is lower primarily because Alberta's top provincial rate is 15% and its bottom rate of 10% applies to a very wide band of income up to $148,269. Ontario's provincial rates reach 13.16% at the top and its surtax mechanism adds additional burden for higher earners, pushing the combined Ontario rate to 53.53%. Alberta also has no provincial sales tax, further reducing the overall tax cost for Alberta residents.
Your marginal tax rate is the rate that applies to the last — or next — dollar of income you earn. Your effective tax rate is the average rate across all your income: total tax divided by total income. Because Canada's system is progressive, your effective rate is always lower than your marginal rate. For example, an Alberta resident earning $120,000 faces a 26% federal marginal rate on their top dollars but an overall effective combined rate of roughly 26%, since the lower brackets shelter the first $114,750 at lower rates.
Incorporation can provide significant tax deferral benefits for business owners, since a CCPC eligible for the Small Business Deduction pays approximately 11% combined tax on active business income in Alberta — far below the top personal marginal rate of 48%. However, incorporation involves additional compliance costs, and the benefit depends on your ability to leave earnings inside the corporation rather than withdrawing them immediately. The optimal structure depends on your income level, RRSP room, personal cash flow needs, and long-term plans. A qualified accountant can model the after-tax outcome for your specific situation before you decide.
