T4 Slips in Canada: 2026 Year-End Payroll Checklist for Small Employers
A practical 2026 T4 payroll year-end checklist for Canadian employers: reconcile pay and deductions, review benefits, prepare slips and avoid common filing mistakes.
If your Canadian small business has employees, preparing T4 slips is an important part of closing the payroll year. A good year-end process starts well before you submit anything to the Canada Revenue Agency (CRA). It means checking that your payroll records, source deductions, employee information and taxable benefits agree.
This plain-language checklist focuses on the 2026 calendar-year payroll records that employers will generally report in early 2027. It is educational information, not personalized tax or legal advice.
What is a T4 slip?
A T4 Statement of Remuneration Paid reports employment income and related payroll amounts for a calendar year. Depending on the employee and their circumstances, it can show employment income, income tax deducted, Canada Pension Plan (CPP) contributions, Employment Insurance (EI) premiums and certain taxable benefits. Employees use their T4 information when preparing their personal income tax returns.
Not every payment to an individual belongs on a T4. For example, genuinely independent contractors are generally treated differently from employees, and some payments may require other reporting. If a worker's status is unclear, review the CRA's employee-versus-self-employed guidance before choosing a slip.
1. Reconcile your 2026 payroll register
Start with a payroll register covering January 1 through December 31, 2026. For every employee, compare total gross pay, deductions and net pay with the payroll system and general ledger. Include regular wages, overtime, vacation pay, bonuses, commissions and other employment payments, as applicable.
Make sure payroll adjustments and reversals are recorded only once. Compare the payroll expense accounts with bank payments, but remember that the timing of pay dates, accruals and remittances can create legitimate differences.
2. Check employee details and employment changes
Review each employee's legal name, Social Insurance Number, address and relevant province of employment information. Check hire and termination dates, changes in payroll status, leaves and any other information that affects the correct slip or deductions. Protect personal data and restrict access to payroll files.
Where a worker has more than one employment arrangement or has moved between provinces, additional care may be needed. Do not assume that the employee's home address determines every payroll rule.
3. Review CPP, EI and income tax deductions
Reconcile amounts deducted from employee pay with the employer's payroll records and CRA remittance account. Check CPP and, where applicable, additional CPP contributions, EI premiums and income tax withheld. Rules and maximums can change by calendar year, and Quebec payroll has distinct requirements.
Investigate differences instead of changing a T4 box merely to make totals match. A missed or incorrect deduction may require a payroll correction and, depending on the facts, further CRA steps.
4. Look for taxable benefits and allowances
Taxable benefits are a frequent year-end surprise. Review employer-paid items such as certain personal-use vehicle benefits, gifts and awards, housing, group benefits, allowances and other non-cash compensation. Whether a benefit is taxable, pensionable or insurable depends on the specific CRA rules.
Keep a supporting worksheet showing the benefit type, value, tax treatment and how it was included in payroll. A reimbursement of a documented business expense is not necessarily treated the same way as a flat allowance.
5. Compare payroll remittances with CRA records
Check your payroll remittance history for the year, including amounts paid, dates and any outstanding balance or credit. The T4 amounts and the remittance account serve different purposes, so reconcile them carefully. Do not confuse an employer's CPP and EI share with the employee deductions reported on the slip.
If the business has missed remittances or discovered errors, deal with them promptly. Interest and penalties may apply depending on the circumstances.
6. Prepare and review T4 slips before filing
Generate a draft T4 for each applicable employee and compare key boxes with the final payroll register. Common boxes include employment income (box 14), CPP contributions (box 16), EI premiums (box 18) and income tax deducted (box 22). Other boxes and codes may apply, including additional CPP information and taxable benefits.
Review totals and spot-check a sample of employee slips against pay statements and benefit worksheets. Make sure employees who left during the year have not been missed.
7. Know the T4 deadline and filing method
T4 information returns and employee copies are generally due by the last day of February following the calendar year. For the 2026 tax year, February 28, 2027 falls on a Sunday; under the CRA's usual weekend-deadline rule, the next business day is generally Monday, March 1, 2027. Confirm the applicable deadline and any CRA updates before filing.
CRA electronic-filing requirements depend on the number and type of information returns. Review the current CRA instructions rather than assuming paper filing is available. The filing process may also determine whether a separate T4 Summary is needed; do not submit duplicate summaries.
8. Give employees their slips and store the records
Provide each employee with their T4 by the applicable deadline using a permitted delivery method. Keep copies of filed slips, submission confirmations, payroll reports, benefit calculations and correspondence. Canadian businesses generally need to retain supporting records for at least six years, subject to specific exceptions and CRA instructions.
Common T4 mistakes to avoid
- Forgetting former employees or a final payroll run.
- Missing a taxable benefit or reporting it in the wrong box.
- Using an incorrect Social Insurance Number or province of employment.
- Confusing gross pay, net pay and employer-paid contributions.
- Assuming a contractor automatically needs a T4.
- Filing before reconciling payroll and CRA remittances.
A simple payroll year-end folder
Create one secure folder for the calendar year with the final payroll register, employee master list, year-end benefit worksheet, remittance history, T4 draft review, filed slips, CRA confirmation and correction log. This makes follow-up easier if an employee asks for a correction or the CRA requests supporting information.
