Payroll in Alberta: A Complete Guide for Employers

Payroll in Alberta is simpler than in any other Canadian province because Alberta has no provincial payroll tax, no Employer Health Tax, and no provincial health premium. Alberta employers deal exclusively with federal payroll obligations, CPP contributions, EI premiums, and income tax alongside WCB Alberta premiums for workplace insurance. This makes Alberta, and Calgary in particular, one of the most employer-friendly environments in Canada for managing payroll. 

This guide covers everything Alberta employers need to know about setting up payroll, calculating deductions, meeting CRA deadlines, and staying fully compliant throughout the year.

Why Payroll in Alberta Is Different From Other Provinces?

Alberta stands apart from every other province in Canada when it comes to employer payroll obligations. Ontario employers must manage the Employer Health Tax on payrolls above $1 million and register with WSIB. BC employers must register with WorkSafeBC and navigate a dual GST and PST tax system. Quebec has its own provincial pension plan and parental insurance scheme.

Alberta has none of these. There is no provincial payroll tax. There is no health premium deducted from employee pay. There is no EHT equivalent. The only provincial-level obligation for most Alberta employers is WCB registration for workplace insurance, which is straightforward to set up and manage. For a complete national framework on how payroll works across all provinces, our guide on payroll management for small businesses in Canada covers every layer of federal and provincial obligation side by side.

Setting Up Payroll in Alberta

Before you start paying employees, you must ensure your business is properly registered and compliant with federal payroll requirements.

1. Register as an Employer With the CRA

The first step for any Alberta employer is to register a payroll program account with the CRA. This is done by adding an RP account to your existing Business Number through the CRA’s Business Registration Online portal. You must complete this registration before your first payday, not after.

Once registered, you receive a payroll program account number in the format 123456789 RP 0001. This number is used on all remittances, T4 filings, and CRA correspondence related to your payroll account.

2. Register With WCB Alberta

Most Alberta employers are required to register with the Workers’ Compensation Board of Alberta within 15 days of hiring their first worker. WCB provides workplace injury and illness coverage to employees, and employers fund the system through annual premiums based on their industry classification and gross Alberta payroll.

WCB registration is completed online through the WCB Alberta website. You will need your business information, a description of your business activities, the date your first worker was hired, and an estimate of your annual Alberta payroll. WCB then assigns your industry rate code, which determines your premium rate.

Payroll in Alberta Explained: The Three Federal Deductions

Alberta employers calculate and remit the same three mandatory federal deductions that apply across Canada. These are Canada Pension Plan contributions, Employment Insurance premiums, and federal and provincial income tax.

1. Canada Pension Plan Contributions

CPP is a federal retirement program funded jointly by employees and employers. For 2025, the CPP contribution rate is 5.95% for both the employee and the employer, applied to pensionable earnings above the basic exemption of $3,500 up to the annual maximum pensionable earnings ceiling. Employers must deduct the employee’s CPP contribution from their pay and match it dollar for dollar as the employer contribution.

Higher-income employees may also be subject to CPP2, the second tier of CPP contributions introduced in 2024. CPP2 applies to earnings above the standard CPP maximum at a rate of 4% for both employee and employer.

2. Employment Insurance Premiums

EI premiums are deducted from every insurable employee’s pay. The employer pays 1.4 times the employee’s EI premium on top of the employee deduction. For 2025, the employee EI premium rate is 1.64% of insurable earnings up to the annual maximum insurable earnings limit. Once an employee reaches the annual maximum, no further EI premiums are deducted for the rest of the calendar year.

3. Federal and Provincial Income Tax

Alberta uses the federal income tax system with its own provincial income tax rates applied on top. Alberta’s provincial income tax starts at 10% on the first $148,269 of taxable income for 2025, with higher rates on income above that threshold. Every new employee must complete a federal TD1 and an Alberta TD1 provincial form before their first payday.

The CRA’s Payroll Deductions Online Calculator handles all three deductions simultaneously and produces the exact amounts to deduct for any Alberta employee based on their gross pay, pay frequency, and TD1 credits.

WCB Alberta Premiums: Rates and Calculations

WCB Alberta premiums are calculated as a rate per $100 of gross Alberta payroll, with the rate determined by your industry classification. Lower-risk industries such as professional services pay significantly lower rates than higher-risk industries such as construction or oil and gas services.

For example, an office-based Calgary business with $250,000 in gross payroll and a WCB rate of $0.20 per $100 would pay $500 in annual WCB premiums. A construction business with the same payroll and a rate of $4.00 per $100 would pay $10,000 annually.

WCB Alberta sets a maximum insurable earnings amount each year. Payroll above this ceiling for any individual worker is not subject to WCB premiums, which provides a natural cost cap for businesses with higher-paid staff.

CRA Remittance Deadlines for Alberta Employers

Once payroll deductions are calculated and withheld, Alberta employers must remit the total amount to the CRA on the schedule assigned to their account. The remittance includes the employee’s CPP, EI, and income tax deductions plus the employer’s matching CPP and 1.4 times EI contributions.

Most new small businesses in Alberta are assigned as regular remitters with a deadline of the 15th of the month following each pay period. Businesses with higher average monthly withholding amounts may be assigned as accelerated remitters with more frequent deadlines. Missing a remittance deadline triggers automatic CRA penalties starting at 3% for amounts one to three days late, rising to 10% for amounts more than seven days late.

Understanding and avoiding these errors is critical. Many Alberta employers also find it helpful to review our guide on payroll deductions in Canada for a deeper look at how CPP, EI, and income tax deductions are calculated correctly, and our resource on payroll mistakes small businesses make to ensure common errors never become your problem.

Year-End Payroll Obligations for Alberta Employers

1. T4 Slips

Alberta employers must prepare a T4 slip for every employee who received employment income during the calendar year. T4 slips must be distributed to employees and filed with the CRA by the last day of February following the tax year. For the 2025 tax year, the deadline is February 28, 2026.

Penalties for late T4 filing are calculated per slip and increase with the number of slips filed late. Accurate T4 slips are also important because employees rely on them to file their personal income tax returns. Errors require amended T4 filings with the CRA, which adds administrative work for both the employer and the employee.

2. WCB Alberta Year-End Payroll Report

At the end of each calendar year, Alberta employers must report their actual gross Alberta payroll to WCB. This reconciliation determines whether the premiums paid throughout the year were sufficient based on actual payroll figures. If actual payroll exceeded the estimate, additional premiums are owing. If it was lower, WCB issues a credit to the account.

Alberta Employment Standards and Payroll

Alberta’s Employment Standards Code sets out the minimum rules that affect how payroll is calculated for Alberta employees. These include overtime pay, vacation pay, general holiday pay, and termination pay. In Alberta, overtime is payable after eight hours in a day or 44 hours in a week at 1.5 times the regular rate. Vacation pay accrues at a minimum of 4% of gross earnings for employees with less than five years of service, rising to 6% after five years. General holiday pay applies to nine designated Alberta statutory holidays each year.

Failure to calculate these amounts correctly creates underpayment claims from employees and potential Employment Standards complaints, both of which carry their own financial and administrative consequences.

Conclusion

Payroll in Alberta is genuinely simpler than in most other Canadian provinces. Without a provincial payroll tax or health premium to manage, Alberta employers can focus entirely on federal CPP, EI, and income tax obligations alongside WCB premiums for workplace coverage. The rules are clear, the tools are accessible, and the compliance path is well-defined.

The key is to register on time, use current CRA rates for every pay period, remit the full amount including employer contributions by the assigned deadline, and file accurate T4 slips and WCB year-end reports by their respective deadlines.
