Alberta’s tax brackets for 2026 run across six provincial rates: 8% on the first $61,200 of taxable income, 10% up to $154,259, 12% up to $185,111, 13% up to $246,813, 14% up to $370,220, and 15% on anything above that.1Government of Alberta. Alberta Taxes and Levies Overview Those provincial rates sit on top of federal income tax, so the actual marginal rate on your next dollar earned ranges from roughly 22% at the low end to 48% at the top.
The Six Alberta Brackets for 2026
Alberta added an 8% introductory bracket in 2025, replacing what had been a flat 10% floor.2Canada Revenue Agency. Alberta Tax Information for 2025 For 2026, every threshold moved up 2% for inflation.1Government of Alberta. Alberta Taxes and Levies Overview
- 8% on the first $61,200
- 10% on income from $61,200.01 to $154,259
- 12% on income from $154,259.01 to $185,111
- 13% on income from $185,111.01 to $246,813
- 14% on income from $246,813.01 to $370,220
- 15% on income above $370,220
The 8% rate benefits every Albertan, not just low earners. A high earner’s first $61,200 is taxed at 8% the same as anyone else’s, with the higher rates only touching the income above each threshold.
Alberta’s Basic Personal Amount
Before any bracket takes a cent, Alberta shelters roughly the first $22,769 of income through the basic personal amount, one of the highest provincial personal amounts in Canada. It works as a non-refundable credit: 8% of the personal amount is subtracted from the provincial tax you would otherwise owe.3Canada Revenue Agency. CPP, EI, and Income Tax Deductions – Alberta
Non-refundable means it can only reduce your Alberta tax to zero. If the credit is larger than your tax bill, you don’t get the difference back. For most employees it applies automatically through payroll deductions; otherwise it flows through Form AB428 on your return.
How the Brackets Actually Work
A raise into a higher bracket doesn’t tax your whole income at the new rate. Only the dollars inside each bracket face that bracket’s rate. Take someone earning $180,000 in 2026:
- First $61,200 at 8% = $4,896
- Next $93,059 at 10% = $9,305.90
- Last $25,741 at 12% = $3,088.92
Provincial tax before credits: $17,290.82. The basic personal amount credit then comes off that total. Only the top slice of income touched the 12% rate, and crossing a threshold never leaves you with less take-home pay from the bracket change alone.1Government of Alberta.

Federal Brackets Stack on Top
Every Alberta resident also owes federal tax on the same income. The 2026 federal brackets are:5Canada Revenue Agency. Income Tax Rates and Income Thresholds
- 14% on the first $58,523
- 20.5% on income from $58,523.01 to $117,045
- 26% on income from $117,045.01 to $181,440
- 29% on income from $181,440.01 to $258,482
- 33% on income above $258,482
The lowest federal rate dropped to 14% for 2026 from the longstanding 15%. The federal basic personal amount is $16,452, shelters that much income from federal tax, and gradually shrinks for higher earners: once net income passes $181,440 the amount is clawed back, hitting a floor of $14,829 at $258,482.6Canada Revenue Agency.

Combined Marginal Rates for Alberta Residents
Stacking Alberta’s six brackets onto the five federal ones produces the combined rate on your next dollar of income:
- Up to ~$16,452: 0% (federal basic personal amount)
- ~$16,453 to ~$22,769: 14% (federal only; Alberta’s personal amount still applies)
- ~$22,770 to $58,523: 22% (14% federal + 8% Alberta)
- $58,524 to $61,200: 28.5% (20.5% federal + 8% Alberta)
- $61,201 to $117,045: 30.5% (20.5% federal + 10% Alberta)
- $117,046 to $154,259: 36% (26% federal + 10% Alberta)
- $154,260 to $181,440: 38% (26% federal + 12% Alberta)
- $181,441 to $185,111: ~41.3% (29% federal + 12% Alberta, plus BPA clawback)
- $185,112 to $246,813: ~42.3% (29% federal + 13% Alberta, plus BPA clawback)
- $246,814 to $258,482: ~43.3% (29% federal + 14% Alberta, plus BPA clawback)
- $258,483 to $370,220: 47% (33% federal + 14% Alberta)
- Above $370,220: 48% (33% federal + 15% Alberta)
Alberta’s top combined rate of 48% remains lower than the equivalent rate in most other provinces, driven by the 8% starting bracket and the relatively generous thresholds before the higher provincial rates apply.1Government of Alberta. Alberta Taxes and Levies Overview
Filing Deadlines and Late Penalties
Your 2025 return, covering both federal and Alberta tax, is due April 30, 2026. Self-employed filers and their spouses have until June 15, 2026, though any balance owing is still due April 30.7Canada Revenue Agency. Due Dates and Payment Dates
Filing late with a balance owing triggers a 5% penalty on that balance plus 1% for each full month the return is outstanding, up to 12 months. If the CRA formally demanded a return and penalized you in any of the three prior years, the rates double: 10% plus 2% per month, up to 20 months.8Canada Revenue Agency.
