Does Alberta have a flat income tax?

Alberta's entry rate of 10% is the lowest base provincial rate in Canada and applies to the large majority of taxpayers. Income above roughly $148,000 moves into higher brackets of 12%, 13%, 14% and 15%, so the system is graduated overall but flat at 10% for most earners.

What is the Alberta basic personal amount?

Alberta provides a generous basic personal amount — about $21,885 — on which no provincial tax is payable. The calculator applies this as a 10% non-refundable credit, which is why low incomes owe little or no Alberta tax.

Is this the same as my total Canadian tax?

No. This is the Alberta provincial portion only. Your total Canadian income tax is the provincial amount plus federal income tax. Use the federal calculator and add the two for your combined liability.

Does this include CPP and EI?

No. Canada Pension Plan contributions and Employment Insurance premiums are separate payroll deductions, not income tax. This tool calculates only Alberta provincial income tax on taxable income.

Is my income data sent anywhere?

No. The calculation runs entirely in your browser using published Alberta brackets and the basic personal amount. Nothing you enter is transmitted or stored.

Alberta Provincial Income Tax Calculator

Alberta has the lowest base provincial income-tax rate in Canada: a 10% rate that covers the vast majority of taxpayers, with graduated upper brackets only kicking in above roughly $148,000. This free calculator estimates the Alberta provincial portion of your income tax, including the basic personal amount credit.

How it works

Alberta tax is calculated on your taxable income using graduated brackets, then reduced by a personal-amount credit:

Graduated brackets are applied: 10% on the first ~$148,269, then 12%, 13%, 14% and 15% on higher slices of income.
Basic personal amount credit of roughly $21,885 is applied at the 10% bottom rate (about $2,188) and subtracted from the gross tax.
The result is your net Alberta provincial tax.

Because the credit is applied at 10% and the first bracket is also 10%, anyone earning at or below the basic personal amount owes no Alberta tax.

Example

A taxpayer with $120,000 of taxable income sits entirely in the 10% bracket. Gross provincial tax is $120,000 × 10% = $12,000. The basic-personal-amount credit of about $2,188 reduces this to roughly $9,812 of net Alberta tax, an average provincial rate near 8.2%.

Notes

This is the provincial portion only — add federal income tax for your combined Canadian liability. It excludes CPP and EI contributions, which are separate payroll deductions, and does not model other Alberta credits. Verify with the CRA or your accountant for filing.
