Alberta Combined Income Tax Calculator

Alberta is Canada’s lowest-tax province for personal income. It is the only province with no sales tax, and its income tax system uses five brackets with the lowest top rate in the country at 15% and the highest Basic Personal Amount at $22,769. The calculator above computes federal income tax plus Alberta provincial income tax and shows total tax, combined marginal rate, average rate, and after-tax income for 2026.

How much income tax does an Alberta resident pay on $85,000?

At $85,000 of taxable income in 2026, an Alberta resident owes approximately $11,318 in net federal income tax and approximately $5,000 in net Alberta provincial tax, for a combined total of approximately $16,318. The after-tax income is approximately $68,682. The combined marginal rate at $85,000 is 30.50%: federal 20.5% plus Alberta 10%.

How Alberta income tax is calculated

Federal component

The federal component is the same across all provinces. For 2026, five brackets apply: 14% on the first $58,523, 20.5% on income from $58,524 to $117,045, 26% on income from $117,046 to $181,440, 29% on income from $181,441 to $258,482, and 33% on income above $258,482. The federal Basic Personal Amount of $16,452 generates a non-refundable credit of approximately $2,303 at the 14% rate.

Alberta’s five provincial brackets

Alberta introduced a low-income bracket in 2025, restructuring its previously simpler bracket system. For 2026, the five brackets are: 8% on the first $61,200; 10% on income from $61,201 to $154,259; 12% on income from $154,260 to $185,111; 13% on income from $185,112 to $246,813; and 15% on income above $246,813. Alberta’s Basic Personal Amount is $22,769, the highest of any province. The BPA credit is calculated at the 10% rate (not the 8% low-income rate), producing a credit of approximately $2,277.

Why Alberta’s tax burden is lowest

Three structural factors produce Alberta’s lowest-in-Canada combined rates at most income levels. First, the 8% first bracket on income up to $61,200 is the lowest first-bracket rate in Canada (excluding Quebec’s federal abatement, which is a different mechanism). Second, the $22,769 BPA is the highest of any province, shielding more income from provincial tax. Third, the 15% top provincial rate is the lowest of any province, cutting in only above $246,813. Alberta also has no provincial sales tax, further reducing the total tax burden on consumption.

Alberta income tax brackets 2026

Worked example: Alberta resident, $100,000 employment income

An Alberta resident reports $100,000 of taxable income in 2026. Federal gross tax: 14% on $58,523 ($8,193) plus 20.5% on $41,477 ($8,503) = $16,696. Federal BPA credit: $2,303. Federal net: $14,393.

Alberta gross tax: 8% on $61,200 ($4,896) plus 10% on $38,800 ($3,880) = $8,776. AB BPA credit: $22,769 × 10% = $2,277. Alberta net: $6,499.

Combined total: $14,393 plus $6,499 = $20,892. Average rate: 20.9%. After-tax income: $79,108. Combined marginal rate: 30.50% (federal 20.5% plus AB 10%).

Rules and edge cases

Alberta versus BC at $150,000

At $150,000 of taxable income, an Alberta resident pays approximately $45,800 in combined income tax for an average rate of 30.5%. A BC resident at the same income pays approximately $48,500 for an average rate of 32.3%. The annual advantage for an Alberta resident at $150,000 is approximately $2,700. At $250,000, the Alberta advantage grows to approximately $8,000 to $10,000 per year because Alberta’s 13% rate applies versus BC’s 16.80% at that level.

The 8% bracket for lower incomes

Alberta’s 8% first-bracket rate on income up to $61,200 (introduced in 2025) makes it significantly more competitive for lower and middle-income earners than the previous flat structure. A resident earning $45,000 pays approximately 8% provincial tax on income above the BPA. Previously, the effective rate on that income was 10%. For a resident earning $55,000, the difference is approximately $400 to $600 per year in reduced provincial tax.

No Alberta Health Premium

Alberta does not levy a provincial health premium on income. Ontario residents pay an annual health premium of up to $900 on top of provincial income tax. BC residents pay indirectly through premiums that were restructured but still embedded in the tax system. Alberta residents pay no equivalent charge, reinforcing the province’s position as the lowest-tax jurisdiction for personal income in Canada.

Alberta Heritage Fund and resource revenue

Alberta’s low provincial tax rates are historically subsidized by resource revenues from oil and gas royalties, which fund provincial programs without requiring equivalent tax levels. When resource revenues fall, Alberta faces fiscal pressure and has historically avoided raising personal income tax rates. The 8% bracket and high BPA represent recent structural choices, not a guaranteed long-term feature of Alberta tax policy.

Alberta at retirement

The combination of Alberta’s low income tax rates, no PST, and no health premium makes it particularly attractive for retirees drawing from RRIFs, defined benefit pensions, and investment accounts. A retiree with $80,000 of combined RRIF and OAS income in Alberta pays approximately $3,500 to $4,000 less in combined income tax annually than the same retiree in Ontario or BC. Over a 20-year retirement, this compounds to a substantial cumulative advantage.
