What Is Payroll Compliance?

Payroll compliance means calculating, withholding, and remitting the correct amounts for every employee, every pay period — and filing the right reports with the CRA on time.

Three Core Deduction Streams

For Canadian employers, payroll compliance covers three primary obligations — each with its own rates, annual maximums, and remittance deadlines.

  • Canada Pension Plan (CPP) contributions
  • Employment Insurance (EI) premiums
  • Federal and provincial income tax withholdings

2026 Rates at a Glance

The CRA updates contribution rates and thresholds annually. Always verify against the current T4032 Payroll Deductions Tables before running your first payroll of the year.

Deduction Employee rate Employer rate 2026 max (employee)
CPP (base) 5.95% 5.95% $3,867.50
CPP2 (second additional) 4.00% 4.00% $396.00
EI 1.66% 2.324% (×1.4) $1,049.12
Federal income tax 15% – 33% — Graduated; no cap
Note: CPP2 was phased in starting in 2024. Employers must match employee CPP2 contributions dollar-for-dollar — but CPP2 does not attract the EI multiplier.

Canada Pension Plan (CPP)

Almost all employees between 18 and 70 who earn above the basic exemption must contribute to CPP. Quebec employees contribute to QPP instead — administered by Retraite Québec.

How CPP Is Calculated

CPP is calculated on pensionable earnings — gross wages minus the annual basic exemption, prorated per pay period. The employer matches every dollar of employee CPP and CPP2 contributions.

  • Prorate the $3,500 annual basic exemption by pay periods
  • Subtract the prorated exemption from gross pensionable earnings
  • Apply the 5.95% rate to the result
  • Stop deducting at the annual maximum ($3,867.50)
  • Calculate CPP2 separately on earnings between the first and second ceiling

Employment Insurance (EI)

EI premiums are deducted from insurable earnings at 1.66% up to the annual maximum insurable earnings ceiling of $65,700 in 2026.

Key EI Rules for Employers

Employers pay 1.4 times the employee premium (2.324%). Some employers with a qualifying short-term disability plan may apply for a reduced multiplier through Service Canada.

  • Insurable hours matter

    Part-time, casual, and term employees all accumulate insurable hours that affect their EI eligibility. Track hours carefully for all worker types.

  • Exceptions to insurable employment

    Owner-operators who control more than 40% of voting shares are generally excluded from EI. Certain family members employed by a corporation may also be exempt.

  • Quebec EI rate

    Quebec operates its own parental insurance plan (QPIP). The federal EI rate for Quebec employees is reduced to reflect the province's separate plan.

Income Tax Withholding

Unlike CPP and EI, income tax is graduated at both federal and provincial levels. The amount withheld depends on the employee's total income and TD1 claim codes.

TD1 Forms

Every new employee must complete a federal TD1 and a provincial TD1 before their first paycheque. These declare personal tax credits that reduce the tax withheld each period.

  • Federal basic personal amount for 2026: $16,129
  • Employees should update their TD1 when their situation changes
  • Retain TD1 forms on file — do not send to the CRA unless requested
  • If no TD1 is submitted, withhold at the highest (claim code 0) rate

Remittance: Paying the CRA

Remittance frequency depends on your average monthly withholding (AMW) from two years prior. Missing a deadline triggers penalties of 3%–10% plus daily compound interest.

Remitter type Average monthly withholding Due date
New employer / Regular Less than $25,000 15th of the following month
Quarterly (small employers) Less than $1,000 (CRA approval required) 15th after each quarter-end
Accelerated Threshold 1 $25,000 – $99,999.99 Within 3 banking days of the 15th and last day of each month
Accelerated Threshold 2 $100,000+ Within 3 banking days of each payday
Penalty reminder: Late payroll remittances trigger penalties even on the first offence. Set automated reminders or use payroll software that tracks your schedule.

Year-End & Common Mistakes

T4 slips and the T4 Summary are due by the last day of February. Employers with 6 or more slips must file electronically through CRA My Business Account.

What Goes on the T4

Every employee receives a T4 slip summarizing their annual earnings and all deductions withheld throughout the year.

  • Box 14 — Total employment income
  • Box 16 / 16A — CPP and CPP2 contributions
  • Box 18 — EI premiums deducted
  • Box 22 — Income tax deducted
  • Box 40 — Taxable benefits (vehicle, parking, group insurance)
  • Union dues, RPP contributions, and other required codes

Common Payroll Compliance Mistakes

These are the errors that most often result in CRA penalties, retroactive assessments, and audit exposure.

  • Misclassifying workers as contractors

    If a worker is economically dependent on your business and you control how they work, the CRA may deem them employees — triggering retroactive CPP, EI, and tax obligations.

  • Missing remittance deadlines

    Late remittances are one of the most common and costly payroll errors. Use payroll software that tracks your remittance schedule automatically.

  • Forgetting taxable benefits

    Company vehicles, group insurance premiums, and employer-paid parking are taxable benefits that must appear on the T4.

  • Not keeping TD1 forms on file

    The CRA can request TD1 forms during an audit. Missing or outdated forms suggest inadequate payroll controls.

  • Applying CPP2 incorrectly

    Some employers apply the base CPP rate to all earnings above the first ceiling instead of switching to the CPP2 rate — resulting in under-remittance and penalties.
