Alberta Income Tax 2025: Why Alberta Has the Lowest Tax in Canada

Alberta is the lowest-taxed province in Canada. That is not an opinion or a marketing slogan — it is arithmetic. No provincial sales tax, the highest basic personal amount in the country, and a starting income tax rate of just 10%. If you earn the same salary in Alberta as you would in Ontario, you keep more of it. Period.

Here is how Alberta’s tax system works for the 2025 tax year and what it actually means for your paycheque.

No Provincial Sales Tax

Alberta is one of the few provinces with no PST. You pay the 5% federal GST on purchases, and that is it. In Ontario, you are paying 13% HST. In BC, you are paying 5% GST plus 7% PST on most goods. In Quebec, it is 5% GST plus 9.975% QST.

This does not show up on your income tax return, but it absolutely affects your cost of living. On a $30,000 car, the difference between 5% GST in Alberta and 13% HST in Ontario is $2,400 out of your pocket. On every major purchase — furniture, electronics, home renovations — Albertans pay thousands less per year in consumption taxes compared to residents of most other provinces.

The Highest Basic Personal Amount in Canada

Alberta’s basic personal amount for 2025 is $22,323. That is the amount of income you can earn before you owe a single dollar of provincial income tax.

Compare that to other provinces:

• Federal BPA: $16,129
• Ontario BPA: $12,747
• BC BPA: $12,932
• Alberta BPA: $22,323

The gap is significant. An Albertan earning $22,000 pays zero provincial income tax. An Ontarian earning the same amount is already paying provincial tax on roughly $9,250 of that income.

Alberta’s Provincial Tax Brackets

Alberta uses a progressive bracket system, starting at 10% — the lowest starting rate of any province.

Taxable Income	Alberta Rate
Up to ~$148,269	10%
$148,269 to ~$177,922	12%
$177,922 to ~$237,230	13%
$237,230 to ~$355,845	14%
Over ~$355,845	15%

That flat 10% on the first $148,269 is the real story. Most working Canadians never leave the first bracket. If you earn $100,000, your entire Alberta provincial tax is calculated at a flat 10% (minus the basic personal amount credit). In Ontario, you would already be in the third provincial bracket, paying rates up to 9.15%.

The top combined marginal rate (federal plus Alberta) sits at approximately 48%. That is significantly lower than Ontario’s top combined rate of about 53.53% or Quebec’s, which exceeds 53%.

How Much You Actually Save in Alberta

Here is a side-by-side comparison for employment income with no additional deductions or credits beyond the basic personal amounts. These are approximate total income taxes (federal plus provincial) for the 2025 tax year:

At $50,000 salary:

• Alberta: ~$7,800
• Ontario: ~$8,800
• Savings in Alberta: ~$1,000/year

At $75,000 salary:

• Alberta: ~$15,100
• Ontario: ~$16,200
• Savings in Alberta: ~$1,100/year

At $100,000 salary:

• Alberta: ~$22,800
• Ontario: ~$24,400
• Savings in Alberta: ~$1,600/year

At $150,000 salary:

• Alberta: ~$38,500
• Ontario: ~$43,200
• Savings in Alberta: ~$4,700/year

The savings get larger as income increases because Alberta’s bracket structure is so much flatter. At $150,000, you are saving almost $400 per month just on income tax — before you factor in the PST savings on everyday spending.

No Health Premium

Ontario charges a health premium on income above $20,000, ranging from $300 to $900 per year. It is calculated on your tax return and added to your provincial tax owing.

Alberta does not have this. Health care is funded through general provincial revenue (largely resource royalties and the 10% income tax). One more line item you do not have to think about.

CPP and EI Are the Same

Alberta uses the same Canada Pension Plan and Employment Insurance as every province except Quebec. For 2025, the CPP employee rate is 5.95% on earnings between $3,500 and $71,300, with CPP2 at 4% on earnings between $71,300 and $81,200. The EI employee rate is 1.64% on insurable earnings up to $65,700.

These payroll deductions are identical whether you live in Calgary, Toronto, or Vancouver. The only province with different rules is Quebec, which runs its own QPP and QPIP programs.

The Trade-Offs

Alberta’s low tax environment is real, but it is not free money. The province funds services differently — relying more heavily on natural resource royalties, which can be volatile. When oil prices drop, provincial budgets tighten and spending debates get heated.

There is also no PST credit or rebate program for low-income Albertans the way some provinces offer sales tax credits. The GST/HST credit from the federal government still applies to all Canadians, but the provincial layer of support is thinner.

And of course, income tax is only one factor in your financial picture. Housing costs, job market, and quality of life vary widely across the country. A person earning $80,000 in Calgary may come out ahead on taxes but face different trade-offs than someone earning the same in Halifax or Winnipeg.

Filing Your Alberta Taxes

Alberta residents file a single income tax return with the CRA, just like residents of every province except Quebec. Your provincial tax is calculated on the same return — you do not need to file anything separately with the Alberta government.

Most tax software handles this automatically. You enter your income, the software applies both federal and Alberta brackets, and you see your refund or balance owing.

The filing deadline for the 2025 tax year is April 30, 2026. Self-employed individuals have until June 15, 2026 to file, but any balance owing is still due by April 30.
