As 2025 approaches, Canadian employers must prepare for a number of payroll tax changes that will directly affect how employee compensation is taxed and reported. These updates span federal and provincial income tax tables, Canada Pension Plan (CPP) and Employment Insurance (EI) contribution rules, payroll reporting requirements, and other statutory obligations. Staying on top of these changes not only ensures compliance with the Canada Revenue Agency (CRA) but also helps employers avoid remittance errors and penalties.

This article provides a comprehensive overview of the key payroll tax changes for 2025 and what employers need to do to prepare.

Federal Income Tax Updates

Income Tax Bracket Adjustments

One of the most significant changes for the 2025 tax year is the reduction of the lowest federal income tax rate. In May 2025, the federal government tabled a Notice of Ways and Means Motion proposing a reduction of the lowest tax rate from 15% to 14%, effective July 1, 2025. Because this change takes effect mid-year, the rate for the full year 2025 is effectively 14.5% for the lowest bracket. Canada+1

Employers should update payroll systems to accommodate the revised tax brackets from the CRA’s updated payroll deduction tables. For 2025, the federal tax brackets using prorated rates are:

  • 0–$57,375: 14%
  • $57,375–$114,750: 20.5%
  • $114,750–$177,882: 26%
  • $177,882–$253,414: 29%
  • Over $253,414: 33% Canada

These updated brackets should be used in payroll withholding from July onward to ensure that taxes are deducted accurately based on current legislation.

Indexation of Personal Amounts

In addition to bracket changes, federal personal tax credits and basic personal amounts have been indexed for 2025. The indexing factor for January 1 is 2.7%, which affects the personal tax credits included in the payroll deduction tables. This indexing increases the amount employees can earn tax-free through basic credits, ultimately affecting how much employers withhold. Canada

Employers should ensure that their payroll systems incorporate the updated personal amounts and indexing adjustments so that tax deductions reflect the correct withholding amounts.

CPP and CPP2 Contributions

Canada Pension Plan Changes

For 2025, the Canada Pension Plan (CPP) continues to evolve under its enhanced contribution framework. The Year’s Maximum Pensionable Earnings (YMPE) has increased to $71,300 from the previous year. The basic exemption remains at $3,500, and the standard CPP contribution rate for both employers and employees remains 5.95%. However, because the YMPE has increased, the maximum employee and employer contributions also rise. University of Calgary in Alberta

Second Tier of CPP (CPP2)

CPP now has a second tier, commonly referred to as CPP2, which applies to pensionable earnings above the yearly maximum up to the Year’s Additional Maximum Pensionable Earnings (YAMPE) — now approximately $81,200 in 2025. Contributions on this tier are made at 4.00% for both employers and employees, with a maximum annual contribution of about $396. Canada+1

This structure means employers will have to calculate two separate CPP contributions for employees earning above the YMPE:

  • Base CPP up to the YMPE, and
  • CPP2 for earnings between YMPE and YAMPE.

Payroll providers and software systems must support these two tiers in calculating CPP contributions accurately. Employers should test payroll systems well before the first pay period of 2025 to ensure compliance and accurate contributions.

Employment Insurance (EI) Premiums

2025 also brings changes to Employment Insurance (EI) premiums:

  • The maximum annual insurable earnings increase to $65,700 (up from $63,200).
  • The employee contribution rate decreases slightly to 1.64% (from 1.66%).
  • The employer contribution rate is set at 2.296% (i.e., 1.4 times the employee rate).
  • Maximum annual premiums rise to $1,077.48 for employees and $1,508.47 for employers. Canada+1

These changes impact how much employers and employees contribute throughout the year. Employers should verify that their payroll systems are using the updated maximum insurable earnings and rates to correctly calculate deductions and remittances.

Provincial and Territorial Payroll Changes

Several provinces and territories have updated their income tax tables and personal amount calculations for 2025. Because payroll withholding varies by jurisdiction, employers must update systems on a province-by-province basis.

Some notable changes include:

Alberta

Alberta is introducing a new tax structure with an 8% rate on the first $60,000 of taxable income. Because this change takes effect mid-year, a prorated rate of 6% applies from July 1 onward. Canada

Manitoba

Manitoba is not indexing its Basic Personal Amount (BPAMB) in 2025, resulting in a prorated amount of $15,591 for the second half of the year. Tax brackets also see prorated adjustments. Canada

Nova Scotia

Nova Scotia’s Basic Personal Amount is being set at $11,744, with specific calculation methods for employees who were taxed under different personal amounts earlier in the year. Canada

These are examples of changes that will affect provincial tax withholdings. Employers should refer to the CRA’s payroll deduction tables for each province and territory to ensure accurate withholding calculations.

Reporting and Compliance Changes

Electronic Filing Requirements

CRA continues to expand digital reporting requirements for payroll:

  • Employers with more than five T4 and T4A slips must file electronically.
  • Real-time reporting pilots are expanding, meaning certain payroll data might need to be submitted more frequently or closer to pay periods. Triple M Professional

Ensuring that payroll software supports CRA’s requirements and that employers are registered for electronic filing well ahead of deadlines is critical. Training payroll staff on electronic submissions can mitigate late filing penalties.

Updated Payroll Deduction Tables

The CRA regularly updates payroll deduction tables throughout the year. For 2025, updated tables are effective for both January 1 and July 1 releases. Employers must download and apply the correct version of T4032 payroll deduction tables from the CRA for the period of the year being processed to ensure compliant tax and contribution withholdings.

Strategic Implications for Employers

Payroll Software and Systems

One of the most important steps for 2025 readiness is validating that payroll systems are ready for:

  • Federal tax bracket changes mid-year,
  • Updated CPP and CPP2 thresholds and rates,
  • New EI insurable earnings and premium rates,
  • Provincial tax rate and credit adjustments, and
  • Electronic filing processes for T4/T4A and other reporting.

Employers should work with payroll providers or internal IT teams to patch software updates early. Testing payroll runs with 2025 tax tables before the first pay is crucial.

Communication With Employees

Payroll changes can affect net pay, even if gross wages haven’t changed. For instance:

  • Increased CPP and EI maximums mean employees may contribute more earlier in the year.
  • Adjusted tax brackets can shift withholding amounts.
  • Changes in personal tax amounts or provincial rates could affect take-home pay.

Preparing clear communication to employees about potential changes in deductions helps build trust and avoids confusion.

Budgeting for Employer Contributions

Changes in thresholds and contribution rates also affect employer costs:

  • Employer EI contributions increase with the maximum insurable earnings.
  • Employer CPP contributions will rise proportional to the increased YMPE and YAMPE.

Employers should budget for these increased statutory costs and integrate them into compensation planning.

Checklist: Preparing for Payroll Tax Changes in 2025

To help employers stay compliant and prepared, here’s a practical checklist:

✔ Confirm payroll software has the latest 2025 CRA deduction tables for federal and provincial taxes.

✔ Validate support for CPP and CPP2 contribution tracking and reporting.

✔ Update EI maximums and premium rates in payroll systems.

✔ Review and test mid-year tax bracket changes scheduled for July 1, 2025.

✔ Train payroll administrators on 2025 reporting requirements and deadlines.

✔ Communicate key changes to employees in advance of the first payroll of 2025.

✔ Coordinate with accounting and finance teams to budget for increased employer payroll costs.

Conclusion

The 2025 payroll tax landscape in Canada presents a range of updates that employers need to account for to remain compliant and efficient. With changes to federal tax rates, CPP and EI contributions, and provincial withholding structures, preparation and system readiness are critical. Employers that proactively update their tools, processes, and communications will ensure smoother payroll operations throughout the coming year.
