Alberta Income Tax Calculator (Combined) Canada

What the Alberta income tax calculator does

The calculator estimates what a year of income costs in federal and Alberta tax combined, and what is left afterwards. Enter an income and any deductions, and the tool runs both bracket tables, applies both basic personal amounts as credits, and reports the total, the average rate and the marginal rate on your next dollar.

Two governments tax the same income in Canada, each with its own brackets and personal amount, and the province you live in on December 31 decides which provincial table applies. Alberta’s table differs from the others in both respects, which is why a general Canadian calculator often leaves Albertans guessing.

How Alberta’s brackets work

For two decades Alberta was the only jurisdiction in Canada with a flat provincial income tax. Higher brackets were later added for large incomes, and a lower bracket was introduced at the bottom. For 2026 the rates are 8% on the first $61,200, 10% from there to $154,259, then 12%, 13%, 14% and finally 15% above $370,220.

For most employees the provincial marginal rate therefore stays at 10% across a wide stretch of income. A worker in another province can cross two or three provincial brackets between $60,000 and $150,000; an Albertan in that range sits in one. That makes planning simpler and keeps the marginal rate in the results stable.

The federal table is the same everywhere in the country and makes up most of the total. On a $90,000 income the federal tax is about twice the Alberta tax, worth remembering before blaming a large bill on provincial policy.

The basic personal amount

Alberta’s basic personal amount, $22,769 for 2026, is the largest of any province or territory by a wide margin. It is applied as a non-refundable credit at the lowest provincial rate, and the calculator shows that credit on its own line.

That amount is why low and modest Alberta incomes produce so little provincial tax despite a first bracket rate higher than several other provinces charge. It is indexed each year.

The federal basic personal amount ($16,452 for 2026) works the same way, and both credits are subtracted after the brackets are applied. Treating them as deductions instead of credits is the most common error in a hand calculation, and it overstates the saving for anyone above the first bracket.

Comparing Alberta with another province

The comparison in the advanced options reruns the provincial half of the calculation for the jurisdiction you choose, on the same taxable income, and reports the difference. A positive difference means Alberta charges less.

That number covers bracket tax and basic personal amounts only. It leaves out the Ontario Health Premium, provincial surtaxes in Ontario and Prince Edward Island, provincial sales taxes and the many jurisdiction-specific credits on a real return. On a middle income the bracket comparison can favour a province with a low first bracket rate; on a high income Alberta usually comes out clearly ahead.

Alberta’s advantage grows with income, is reinforced by the absence of a provincial sales tax, and is smallest for households in the first bracket.

Deductions, and what they change

Two deduction fields are available. An RRSP contribution and other deductions both reduce income before the brackets are applied, so both cut the federal and provincial bills at your marginal rate rather than at the average rate.

The tool reports the taxable income it used. Income after tax is gross income less tax, not less the contribution, because an RRSP contribution moves money rather than spending it. For the cash figure after both tax and saving, subtract the contribution yourself.

The second field is for deductions such as union and professional dues, childcare expenses, moving expenses, employment expenses supported by a signed T2200, and support payments. Medical expenses, donations, tuition and the disability amount are credits, which reduce tax rather than income, and the dedicated tools handle them.

Average rate against marginal rate

The average rate is the whole bill divided by the whole income. Use it for budgeting, for comparing years and for the share of your income that goes to tax.

The combined marginal rate is the tax on the next dollar. Use it for decisions at the margin: whether an overtime shift is worth taking, what a bonus will deliver, and how much an RRSP contribution saves. On a $90,000 Alberta income the average rate is about 20% and the marginal rate is 30.5%.

Where this estimate stops

The calculator covers federal and Alberta personal income tax on employment or self-employment income, with the two basic personal amounts. It does not model CPP or EI contributions, dividend or capital gains treatment, the Canada workers benefit, spousal and dependant credits, or the alternative minimum tax that can apply in years with large capital gains or stock options.
