What Are Payroll Source Deductions in Canada? A Complete Guide for Employers

Payroll source deductions are a legal and financial responsibility for every Canadian employer with staff on payroll. Every time you pay salaries or wages, you are responsible for deducting and sending certain amounts to the government on your employees’ behalf.

Whether you’re a new business owner grappling with payroll management or an HR specialist in need of a payroll source deductions crash course, this guide explains them in plain language.

Keep reading and you will learn what these deductions are, how they are calculated, your responsibilities, and the common pitfalls that lead to penalties and CRA issues.

Understanding Payroll Source Deductions: Definition and Purpose

Payroll source deductions are mandatory amounts that employers withhold from employees’ pay at the source. These deductions fund key government programs such as the Canada Pension Plan (CPP), Employment Insurance (EI), and federal and provincial income taxes.

In practical terms, employers act as intermediaries between employees and the government. You collect these deductions from each paycheque and remit them to the Canada Revenue Agency (CRA) or Revenu Québec on time and in full.

The Legal Framework Behind Payroll Deductions

Payroll deductions are governed by several key pieces of Canadian legislation:

• Income Tax Act
• Canada Pension Plan Act
• Employment Insurance Act
• Provincial employment standards and tax laws

From our experience at Premium Bookkeeping & Accounting working with Canadian small businesses, payroll source deductions rank among the top issues where well-intentioned employers face CRA trouble – not from avoidance, but from misunderstandings on remittance schedules, incorrect setups, or over-relying on software defaults

Understanding the rules—and having a simple, consistent process—helps you stay compliant and avoid surprises.

The 3 Mandatory Payroll Source Deductions in Canada

Every employer in Canada is required by law to deduct and remit three core payroll source deductions for each employee:

1. Canada Pension Plan (CPP) Contributions

CPP is a retirement pension plan funded by contributions from both employees and employers. The current (2025) contribution rate is 5.95% for both, up to an annual maximum (the Year’s Maximum Pensionable Earnings, or YMPE). For 2026, the YMPE is set to $74,600.

• Employee contribution: 5.95% of pensionable earnings above $3,500 up to YMPE
• Employer contribution: Matches the employee’s amount
• Remittance: Both amounts are withheld and remitted together
• Self-employed remittance: Set at 11.9% for 2026

Example:

If an employee earns $60,000 (below the YMPE):

CPP contribution = (60,000 – 3,500) × 5.95% = $3,363.25 (each, employee and employer)

Canada has a second earnings ceiling (often referred to as CPP2) above the YMPE.

Second ceiling  Year’s additional maximum pensionable earnings (YAMPE): $85,000 for 2026.

• CPP2 employee rate: 4.00%
• CPP2 employer rate: 4.00%
• Maximum CPP2 employee (and employer) contribution: $416 for 2026.

For a full picture of how CPP, EI, and other payroll costs are changing this year — including employer dollar-impact examples — see our 2026 Canadian tax changes guide for small business.

If you’re self-employed, the maximum annual self-employed contribution for 2026 is $832.

Employers must account for CPP2 when an employee’s pensionable earnings exceed the YMPE.

2. Employment Insurance (EI) Premiums

EI provides temporary income support to workers who lose their jobs or take certain types of leave. The 2025 EI rate is 1.64% for employees, with a maximum annual premium of $1,077.48. For 2026, Canada Employment Insurance Commission set the EI rate at 1.63% with a maximum annual employee premium of $1,123.07.

Employers must contribute 1.4 times the employee’s premium. For 2026, the maximum annual employer premium is $1,572.3.

The Maximum Insurable Earnings (MIE) is $65,700 as of 2025 and $68,900 for 2026.

Quebec EI premium rates for 2026 is 1.3% with maximum annual employee premium at $895.70 and maximum annual employer premium at $1,253.98.

• Employer premium: 1.4 × employee’s premium
• Remittance: Both amounts sent to CRA
• Quebec employers: remit to Revenu Québec

Employers withhold EI from employees and remit both the employee and employer portions.

3. Federal and Provincial Income Taxes

Canada operates a progressive tax system. Employers must withhold the correct amount of federal and provincial/territorial income tax from each paycheque, based on the employee’s total income, province of employment, and TD1 forms.

• Federal tax: Calculated using CRA tax tables and the employee’s TD1 form
• Provincial/territorial tax: Varies by province; also based on TD1P form

Example:

An Ontario employee earning $65,000 annually will have both federal and Ontario income taxes withheld from each pay period, calculated using the CRA’s payroll tables or online calculator.

Assume an employee outside Quebec earns $65,000 in 2025.

• CPP (base): earnings exceed the basic exemption and are below YMPE ($71,300), so CPP is calculated on $65,000 − $3,500 = $61,500.
  • Employee CPP: $61,500 × 5.95% = $3,659.25
  • Employer CPP: $3,659.25
• EI: earnings are below MIE ($65,700)
  • Employee EI: $65,000 × 1.64% = $1,066.00
  • Employer EI: $1,066.00 × 1.4 = $1,492.40
• Income tax: depends on province, TD1 claims, and pay frequency (use Payroll Deductions Online Calculator for accuracy).

Tips and Gratuities: When They’re Subject to Source Deductions

If you employ tipped staff, whether tips run through payroll depends on one question: does the money pass through the employer’s hands?

Controlled tips — tips you collect or possess and pay out (mandatory service charges, employer-run pools, tips banked and redistributed) — are pensionable and insurable.

Direct tips pass straight from customer to employee (cash left on the table). No employer CPP or EI, not on the T4; the employee reports them on Line 10400. (They can still elect CPP via Form CPT20.)

The part that catches employers off guard: how tips are paid now matters as much as how they’re pooled. In Ristorante a Mano Limited v. Canada (2022 FCA 151), the Federal Court of Appeal found electronic tips are subject to CPP and EI. With most tipping electronic, a pool you think is “direct” can be treated as controlled based on how the money moves.

For how tip handling fits alongside daily sales, HST, and inventory, see our guide to restaurant bookkeeping in Canada.

Employer Responsibilities for Payroll Source Deductions

Registering for a Payroll Program Account

Before withholding and remitting source deductions, employers must register for a CRA payroll program account (RP account). This can be done online, by mail, or by phone.

The steps to register for a payroll program account are:

1. Gather business number, legal name, address, and business structure.
2. Register via CRA’s Business Registration Online (BRO) or by contacting CRA directly.
3. Receive your payroll account number.

Maintaining Proper Payroll Records

Employers must keep detailed payroll records for each employee, including:

• Gross earnings and hours worked
• All deductions (CPP, EI, tax, voluntary)
• Employer contributions
• Pay periods and payment dates
• TD1 and TD1P forms
• Records of remittances to CRA

It is important to keep records for at least six years after the last year they relate to, in accordance with CRA requirements.

How to Calculate Payroll Source Deductions Accurately

The Canada Revenue Agency provides several tools and resources to help employers calculate payroll deductions accurately. Accurate deductions are essential for compliance and employee trust. 

Using the Payroll Deductions Online Calculator (PDOC)

The CRA’s Payroll Deductions Online Calculator (PDOC) is a free, up-to-date tool for calculating deductions for any pay period.

• Access at: CRA PDOC
• Enter employee details (province, pay frequency, salary, TD1 claims)
• The tool provides exact amounts for CPP, EI, and taxes

At Premium Bookkeeping & Accounting, when a client comes to us for payroll management services, we cross-check every payroll run with PDOC—especially for new hires, bonuses, or changes—rather than trusting software alone, as we’ve seen discrepancies cause CRA issues.

Understanding Payroll Deduction Factors

Payroll deduction amounts may vary for each employee. Key factors influencing payroll deductions include:

• Employment status (full-time, part-time, contract)
• Pay frequency (weekly, biweekly, monthly)
• Province/territory (each province and territory has unique tax rates)
• TD1/TD1P forms (personal tax credits claimed by the employee)
• Other benefits or taxable allowances

Remember to always update TD1 forms for new hires and when an employee’s personal situation changes.

Payroll Source Deductions Remittance: Deadlines and Procedures

Determining Your Remitter Type

The CRA classifies employers based on their average monthly withholding amount (AMWA). Your remitter type determines how often you must remit deductions:

• Regular remitter: Monthly (this is the option most small businesses use)
• Quarterly remitter: For eligible small employers
• Accelerated remitter (Threshold 1): Up to twice monthly
• Accelerated remitter (Threshold 2): Up to four times monthly

Remittance Deadlines by Remitter Type

• Regular remitter: 15th of the month after the month of deduction
• Accelerated (Threshold 1): 25th of the same month for 1st–15th, 10th of the following month for 16th–end
• Accelerated (Threshold 2): 3rd working day after each pay date
• Quarterly: 15th of the month after the quarter ends

Exception: If the deadline falls on a holiday or weekend, remit on the next business day.

Employers can remit payroll deductions online through CRA My Payment, through financial institutions, or by mail using a remittance voucher.

Late remittances from cash flow or calendar slips are common; CRA penalties hit regardless. At Premium Bookkeeping and Accounting, we build in automation, reminders, and monthly reconciliations to prevent this.

Payroll remittance deadlines don’t exist in isolation — they run alongside corporate tax instalments, T4/T5 filing, and GST/HST returns throughout the year. For a month-by-month view of how these overlap, see our 2026 corporate tax deadlines calendar.

Special Considerations for Quebec Employers

Quebec has unique payroll deduction rules and remittance processes. If you are an employer in Quebec, you must comply with the specific provincial requirements.

Quebec Pension Plan (QPP) vs. Canada Pension Plan (CPP)

• QPP replaces CPP for Quebec employees.
• 2025 QPP rate: 6.4% (up to the YMPE, $71,300 for 2025).
• Employers and employees each contribute 6.4%.

New changes or the portion of the pensionable salary or wages that does not exceed the maximum pensionable earnings under the QPP for 2026 are shown below:

• Maximum pensionable earnings – $74,600
• Basic exemption – $3,500
• Maximum contributory earnings – $71,100
• Contribution rate (base contribution rate of 5.30% and first additional contribution rate of 1%) – 6.30%
• Employee’s maximum contribution – $4,479.30
• Employer’s maximum contribution (per employee) – $4,479.30

QPP for the portion of the pensionable salary or wages that exceeds the maximum pensionable earnings under the QPP for 2026:

• Additional maximum pensionable earnings – $85,000
• Maximum pensionable earnings – $74,600
• Additional maximum contributory earnings – $10,400
• Second additional contribution rate – 4% 
• Employee’s maximum second additional contribution – $416
• Employer’s maximum second additional contribution (per employee) – $416

Quebec Parental Insurance Plan (QPIP)

• QPIP is a mandatory deduction for parental leave benefits in Quebec.
• 2025 maximum insurable earnings is $98,000.
• 2025 QPIP rates: 0.494% for employees, 0.692% for employers (up to annual maximum).
• Employers remit to Revenu Québec, not the CRA.

The 2026 Québec parental insurance plan (QPIP) premiums are shown below:

• Maximum insurable earnings – $103,000
• Employee’s premium rate – 0.430%
• Employee’s maximum premium – ($103,000 × 0.00430) $442.90
• Employer’s premium rate – 0.602%
• Employer’s maximum premium (per employee) – ($103,000 × 0.00602) $620.06

Note: Quebec employers must also withhold the provincial income tax, which is remitted to Revenu Québec.

Common Mistakes to Avoid with Payroll Source Deductions

Common errors employers and small businesses make when remitting payroll deductions include:

• Late or missed remittances
• Incorrect calculation of deductions
• Not updating TD1/TD1P forms
• Failing to keep proper records

It is important to adhere to payroll remittance deadlines and keep adequate records in a safe place to avoid penalties for non-compliance.

Penalties for Non-Compliance

• 10% of the amount not remitted on time (20% for repeated failures)
• Interest charges
• Potential criminal prosecution for repeated or egregious non-compliance

Best Practices for Payroll Compliance

Here are some best practices to keep your business’s payroll process compliant with the CRA requirements:

• Use the CRA PDOC and T4032 tables for every pay run
• Schedule reminders for remittance deadlines
• Conduct regular payroll audits and reconcile payroll records
• Consult a payroll professional or accountant for complex situations
• Keep all payroll records organized and up to date

At Premium Bookkeeping, we work hands-on with Canadian businesses to build audit-ready, streamlined payroll processes that stand up to CRA scrutiny and give you peace of mind.

Payroll Source Deductions vs. Other Payroll Deductions

Not all payroll deductions are mandatory source deductions. Employers may also process voluntary deductions and court-ordered garnishments.

Voluntary Payroll Deductions Explained

These are deductions made with the employee’s written consent, such as:

• Group insurance premiums
• RRSP contributions
• Charitable donations
• Union dues
• Company loans or advances

Employer’s role:

• Obtain written authorization
• Remit amounts to the appropriate third parties
• Refund any over-deductions promptly

An employee must provide documented consent for voluntary payroll deductions. 

Handling Garnishments and Other Legal Deductions

Court-ordered garnishments require employers to deduct a specified amount from an employee’s pay and remit it to the court or creditor.

Best practices for handling garnishments and legal deductions are:

• Follow the court order exactly
• Prioritize statutory source deductions (CPP, EI, tax) before garnishments
• Keep detailed records of all deductions and remittances
