Why Payroll Compliance Matters
Employers are legally required to:
Pay employees accurately and on time
Withhold and remit taxes
Provide clear earnings statements
Follow employment standards (minimum wage, overtime, leave entitlements)
Failure to comply with payroll regulations can lead to penalties, legal action, and loss of employee trust. That’s why staying on top of both Canadian payroll rules and U.S. payroll laws is non-negotiable for any business with a North American workforce.

Payroll Laws in Canada
1. Federal vs. Provincial Payroll Rules
In Canada, payroll is governed by both the federal government and provincial or territorial employment standards. Most employees fall under provincial laws, except those in federally regulated industries like banking or transportation.
2. Mandatory Payroll Deductions in Canada
Employers must deduct the following from employee wages:
Federal Income Tax
Canada Pension Plan (CPP) contributions
Employment Insurance (EI) premiums
These deductions must be remitted to the Canada Revenue Agency (CRA) on a regular schedule.
3. Minimum Wage and Overtime
Each province sets its own minimum wage and overtime rules. For example:
Ontario minimum wage: $16.55/hour
Alberta minimum wage: $15.00/hour
Overtime is typically paid at 1.5x the regular rate after 44 hours/week (varies by province)
4. T4 Slips and Year-End Reporting
At the end of the calendar year, employers must issue T4 slips summarizing an employee’s earnings and deductions. These are submitted to both the CRA and employees.

Payroll Laws in the United States
1. Federal and State Payroll Requirements
Payroll in the U.S. is regulated at both the federal and state levels. The Fair Labor Standards Act (FLSA) sets nationwide standards, but many states have stricter laws on wages, breaks, and leave policies.
2. Required Payroll Deductions in the USA
U.S. employers must withhold:
Federal Income Tax
Social Security Tax
Medicare Tax
Many states also require state income tax withholding, and some have disability insurance and unemployment tax requirements.
3. Minimum Wage Differences
The federal minimum wage is $7.25/hour, but many states (and even cities) have higher rates:
California: $16.00/hour
Washington: $16.28/hour
States may also have different overtime laws, meal breaks, and rest periods.
4. W-2 Forms and Annual Filing
At year-end, employers must issue W-2 forms to employees and file them with the IRS and Social Security Administration. This form reports total earnings, withheld taxes, and other compensation.
