Province- and territory-specific withholding references used to calculate non-Quebec provincial income tax deductions.
Provincial tax tables are the province- or territory-specific payroll withholding tables payroll uses to help calculate provincial or territorial income tax deductions where that treatment applies.
In plain language, they are part of the reference material payroll uses to withhold the correct tax from pay. They matter because payroll does not calculate income tax by guesswork, and the provincial side of withholding is not identical across jurisdictions.
Provincial tax tables matter because they affect:
They are especially important because employees often see only one tax effect on the paycheque, while payroll has to work through the province-specific withholding mechanics behind that result.
In Canadian payroll, provincial or territorial tax tables are used with the rest of the payroll information for the employee, including the applicable pay frequency, taxable earnings, and payroll form inputs. Payroll uses those tables, formulas, or an official calculator to determine the province-linked part of tax withholding.
That means provincial tax tables are closely connected to:
Quebec needs special care in this conversation. Quebec payroll should not be flattened into an ordinary non-Quebec provincial tables discussion because Quebec uses its own provincial payroll framework.
Payroll processes two similar employees, but one is in Alberta and the other is in Ontario. Payroll uses the applicable province-specific withholding reference for each employee so the provincial income tax deduction is not treated as a one-size-fits-all national amount.
Table content, formulas, and withholding references change over time. This page explains the role of provincial tax tables in payroll vocabulary, not the live rates or table values for a specific pay run.
