Payroll Basics for Canadian Small Businesses

Payroll is one of those business tasks that looks simple until the first deadline arrives.

Paying an employee is not only transferring wages. You have to determine the worker’s status, set up the right payroll account, calculate deductions, remit on time, keep records, issue slips, and understand which rules apply where the employee works.

The basics are manageable, but they need a routine.

Know Whether the Worker Is an Employee

Payroll starts with worker status.

The CRA says employment status affects CPP, EI, and income tax withholding obligations. If a worker is an employee, the employer is responsible for deducting CPP contributions, EI premiums, and income tax where required, then remitting those amounts along with the employer’s share of CPP and EI.

The contract label is not enough. The facts of the relationship matter, including control, tools, chance of profit, risk of loss, integration into the business, and other factors.

If the worker is really an employee, treating them as a contractor can create back deductions, penalties, interest, and employment law issues.

Open a Payroll Program Account

If you have employees, you generally need a CRA payroll program account.

The CRA says new employers have to register for a payroll account before the first remittance due date. A payroll account is attached to your business number and is used to remit payroll deductions and file employer information returns.

If you are incorporated, confirm that the payroll account is attached to the correct corporation, not the owner’s personal business account. If you operate in Quebec, you may also have Revenu Quebec source deduction and employer contribution obligations.

Open the account before the first payday calendar gets busy.

Collect Employee Information Before Paying

Payroll calculations depend on employee information.

The CRA says employers should get the employee’s social insurance number, determine the province of employment, and get completed federal and provincial or territorial TD1 forms before paying an employee.

The employee’s province of employment matters because payroll deductions are generally based on where the employee reports to work through an establishment of the employer. Remote and cross-province situations can be more complicated, so confirm the rules if the employee works from another province or territory.

Store SINs, TD1 forms, banking details, and payroll records securely. Payroll files contain sensitive personal information.

Understand What You Deduct

Payroll deductions usually include income tax, CPP contributions, and EI premiums.

The exact calculation depends on the type of pay, employee situation, province or territory of employment, exemptions, maximums, taxable benefits, pensionable or insurable earnings, and special cases.

The CRA provides the Payroll Deductions Online Calculator for federal, provincial, and territorial deductions, except Quebec. CRA guidance also includes payroll deduction tables and formulas for employers that calculate payroll another way.

Do not estimate deductions manually unless you know exactly what you are doing. A small mistake repeated every pay period can become a large year-end problem.

Remember the Employer Portion

Payroll cost is not only the employee’s gross wage.

Employers generally pay their own CPP contribution and EI premium amounts in addition to the amounts withheld from the employee. Other employer costs may include vacation pay, statutory holiday pay, benefits, workers’ compensation premiums, employer health taxes in some provinces, payroll service fees, and accounting support.

If you are budgeting for a new employee, include the employer portion before making the offer.

This is especially important for small businesses with tight cash flow. The amount withheld from the employee is not business cash to spend.

Remit Source Deductions on Time

Once deductions are withheld, they need to be remitted.

CRA remittance due dates depend on the employer’s remitter type. Regular remitters generally remit by the 15th day of the month after the month they pay employees, while quarterly and accelerated remitters follow different schedules.

The CRA can change your remitter type based on your average monthly withholding amount. That means the schedule you start with may not be the schedule you use later.

Put remittance dates on a calendar and reconcile them after each payroll. Late or missing remittances can lead to penalties, interest, and cash flow problems.

Keep Payroll Records

Payroll records support deductions, remittances, slips, and employment records.

The CRA says payroll records include the hours worked by each employee and the amounts withheld for CPP, EI, and tax. You should also keep employee information, TD1 forms, pay period details, gross pay, taxable benefits, vacation pay, reimbursements, source deduction calculations, remittance confirmations, T4 slips, Records of Employment where required, and payroll reports.

The CRA’s general record-keeping guidance says records generally need to be kept for six years from the end of the last tax year they relate to, unless the CRA gives permission to destroy them earlier.

Good payroll records make corrections easier. They also protect the business if a former employee, bookkeeper, accountant, or government office asks questions later.

Issue T4 Slips and Employer Returns

Payroll does not end with the last paycheque of the year.

Employers generally need to file T4 information returns and give employees their T4 slips by the last day of February following the calendar year. If the deadline falls on a Saturday, Sunday, or public holiday recognized by the CRA, the next business day rule may apply.

If you paid contractors, directors, pension income, fees, commissions, or other amounts, other slips may apply. Do not assume every payment belongs on a T4.

Before year-end, review employee names, SINs, addresses, taxable benefits, pensionable earnings, insurable earnings, remittances, and payroll balances.

Know When to Issue a Record of Employment

A Record of Employment is used for Employment Insurance purposes.

You may need to issue an ROE when an employee has an interruption of earnings. Timing and method can depend on whether you issue electronic or paper ROEs.

Do not wait until an employee asks for one. If there is a layoff, termination, leave, shortage of work, or other interruption, check the ROE rules promptly.

Payroll software can help, but someone still needs to know when an ROE event has happened.

Handle Quebec Payroll Separately

Quebec payroll is different from the rest of Canada.

Revenu Quebec says employers may need to calculate source deductions of Quebec income tax, employee and employer Quebec Pension Plan contributions, Quebec parental insurance plan premiums, employer health services fund contributions, labour standards contributions, and other amounts where applicable.

The CRA’s Payroll Deductions Online Calculator does not calculate Quebec provincial payroll deductions. If you have employees in Quebec, confirm both CRA and Revenu Quebec obligations before paying them.

This is not a place for guesswork. Quebec payroll can affect registration, deductions, remittances, slips, and employer contributions.

Watch Taxable Benefits and Reimbursements

Not every payment or benefit is treated the same way.

Bonuses, commissions, allowances, gifts, vehicle benefits, parking, meals, phone plans, internet, tools, relocation support, group benefits, and expense reimbursements can have different payroll treatment.

Some amounts may be taxable benefits. Some may be reimbursements. Some may affect CPP, EI, income tax, GST/HST, or reporting.

If you are adding benefits or paying unusual amounts, check the CRA rules before running payroll.

Build a Payroll Calendar

Payroll improves when it runs on a calendar.

Set dates for pay periods, payday approvals, timesheet cutoffs, payroll processing, direct deposit deadlines, source deduction remittances, workers’ compensation reporting, benefit payments, T4 review, ROE events, and year-end filing.

Also decide who checks payroll before it is finalized. A second review can catch wrong hours, missing vacation pay, taxable benefit issues, new employee errors, and terminated employee access.

The goal is to avoid finding payroll problems only after money has moved.

Get Help Before Payroll Gets Messy

Small payroll errors can repeat quietly.

A bookkeeper, payroll provider, or accountant can help set up accounts, calculate deductions, review remittance schedules, prepare T4s, and correct old issues. If you are not sure whether you need a bookkeeper or accountant, Tech Help Canada has a related guide on when to hire an accountant vs. a bookkeeper.

You can also browse Canadian service providers in the Tech Help Canada Business Directory if you need payroll, bookkeeping, accounting, or HR support.

Before You Run Payroll

Before paying employees, confirm worker status, payroll account setup, employee SIN and TD1 forms, province of employment, deduction calculations, employer contributions, remittance dates, payroll records, T4 obligations, ROE rules, and Quebec-specific requirements where relevant.

Payroll does not need to be dramatic. It does need to be accurate, documented, and repeated on time.
