Step 1: Set Up Your CRA Payroll Account and Business Number

CRA payroll compliance starts with one account. Before you pay a single employee, you need a payroll deductions account linked to your business number.

Register through the Canada Revenue Agency’s online portal. You will need your business number, your legal name, and an estimate of your monthly payroll. The CRA issues your account number right away.

Here is what to gather before you start:

• Your business number and legal operating name
• Owner or director identification
• Expected pay period frequency (weekly, biweekly, semi-monthly, or monthly)
• Your first hire date

One mistake we see often: owners register late, after the first payday. That leaves deductions owing with no account to remit them to. Register before the first cheque clears.

Step 2: Calculate CPP and EI Deductions Correctly

Getting CPP and EI right is the core of how to calculate CPP and EI deductions. Every pay period, you withhold employee portions and add your employer share.

The formula is simple in structure:

1. Start with gross pay for the period.
2. Deduct the employee’s CPP contribution based on pensionable earnings.
3. Deduct the employee’s EI premium based on insurable earnings.
4. Withhold income tax using the federal and provincial TD1 forms.
5. Add the employer’s CPP and EI share on top.

Rates and maximums change each January. Always confirm current figures with the CRA payroll deductions tables before your first run of the year.

A common mistake is applying one flat rate to every employee. CPP has an annual ceiling, and EI has its own. Once an employee hits the ceiling, you stop deducting for the rest of the year.

Step 3: Know Your CRA Payroll Remittance Deadlines

CRA payroll remittance deadlines depend on your remitter type, and this is where many small businesses slip. Your remitter type is assigned by the CRA based on your average monthly withholding, and it determines both how often you remit and when each payment is due.

The four remitter types work like this:

Remitter Type	How You Qualify	Remittance Frequency	Due Date
Quarterly	Average monthly withholding under $3,000	Every 3 months	15th of the month after the quarter ends
Regular	Average monthly withholding of $3,000 to $14,999	Monthly	15th of the following month
Threshold 1	Average monthly withholding of $15,000 to $49,999	Twice monthly	25th for the first half of the month; 10th of the following month for the second half
Threshold 2	Average monthly withholding of $50,000 or more	Up to 4 times monthly	Set schedule assigned by the CRA

A few mechanics that matter in practice:

• The CRA reviews your remitter type periodically and can move you up or down a tier. A seasonal spike in payroll can push you into a faster remittance schedule, so check your account after any unusual hiring or bonus cycle.
• If the 15th falls on a weekend or holiday, the deadline moves to the next business day. The same rule applies to the 25th and the 10th.
• New employers are typically assigned quarterly or regular status until the CRA has enough history to reassess.

Build a reusable compliance calendar rather than relying on memory. A practical pattern is:

• Monthly: confirm your remitter type on the CRA online account, reconcile the prior month’s remittance confirmation, and flag any pay period where withholding crossed a threshold.
• Quarterly: if you are a quarterly remitter, remit by the 15th of the month after quarter end; review year-to-date CPP and EI ceilings for each employee.
• Annually: file T4 slips and the T4 Summary by the last day of February, and reconcile total remittances against total deductions for the year.

Pay electronically through your bank or the CRA online account. Keep the confirmation number. It is your proof if a payment is ever questioned.

Step 4: Follow a Payroll Compliance Checklist for Employers

A payroll compliance checklist for employers turns a stressful month-end into a routine. Run the same steps every pay period.

• Confirm hours, salaries, and any bonuses for the period
• Verify TD1 forms are current for each employee
• Calculate CPP, EI, and income tax using current rates
• Review taxable benefits and add them to gross pay
• Approve the payroll register before release
• Issue pay and pay stubs
• Remit source deductions by the due date
• File and store the remittance confirmation
• Reconcile the payroll register against bank records

This checklist is where payroll controls live. A second person reviewing the register catches most errors before they reach the CRA.

Step 5: Keep Payroll Records and Reconcile Every Pay Period

Recordkeeping is not glamorous, but it is the backbone of CRA payroll compliance. The CRA can ask to see your records at any time.

Keep these for each employee:

• Payroll register showing gross pay, deductions, and net pay
• Pay stubs and pay period dates
• TD1 federal and provincial forms
• Remittance confirmations
• T4 slips and the T4 Summary

The CRA generally requires payroll records be kept for six years from the end of the last tax year they relate to. Store them digitally and back them up.

Reconcile every pay period, not just at year-end. Compare your payroll register to your bank statement and your CRA account balance. Small gaps caught early stay small.

Reconciliation is the difference between a clean year-end and a scramble in February.

Step 6: Handle Corrections, Missed Remittances, and Worker Classification

Mistakes happen. What matters is how fast you fix them, and in what order.

Missed or late remittances

If you miss a remittance, pay as soon as possible. The CRA charges a penalty based on how late the payment is, plus daily interest. The penalty rate steps up with each repeat late payment in the same year, so a second miss costs more than the first.

A practical recovery sequence:

1. Remit the full amount owing immediately, even if you cannot yet explain the shortfall.
2. Pull the remittance confirmation and note the payment date.
3. Check your CRA online account for any penalty or interest assessment.
4. If the shortfall was caused by a calculation error, correct the next payroll run so the gap does not repeat.
5. If you believe the penalty is wrong, request a relief review in writing through the CRA.

Voluntary disclosure, done before the CRA contacts you, can reduce penalties. The key word is before, once the CRA opens a review, the relief options narrow.

Deduction errors

For a deduction error, correct it in the next pay period rather than waiting for year-end.

• If you underdeducted CPP or EI, recover the employee portion through payroll within the CRA’s allowed timeframe. If the amount is small, some employers absorb it rather than create a repayment burden.
• If you overdeducted, refund the employee through payroll and adjust your remittance accordingly.
• If the error affects a T4 already issued, file an amended T4 slip and an amended T4 Summary. Do not simply overwrite the original, the CRA matches amended slips against the original filing.

Worker classification

Worker classification deserves its own attention because misclassification means unpaid CPP, EI, and income tax, plus penalties and interest.

The CRA looks at the whole relationship, not just the contract title. The factors that carry the most weight:

• Control: who sets hours, assigns work, and supervises day to day
• Ownership of tools: who provides equipment and covers expenses
• Chance of profit and risk of loss: whether the worker can profit or lose money on the arrangement
• Integration: whether the worker is part of your core operations
• Exclusivity: whether the worker serves other clients

A contractor who works set hours, uses your equipment, and takes direction may be an employee in the CRA’s eyes regardless of what the contract says. Review contracts and working arrangements yearly, and document the reasoning behind each classification decision.

Step 7: CRA Payroll Audit Preparation and Response

CRA payroll audit preparation starts long before any letter arrives. A clean paper trail is your best defense.

When the CRA reviews your payroll account, it typically asks for payroll registers, remittance records, T4s, and worker contracts. Have these organized by year.

Our audit response workflow:

1. Read the CRA letter carefully and note the response deadline.
2. Assign one person to own the response.
3. Pull the requested records and cross-check them against your CRA account.
4. Fix any errors you find before responding.
5. Respond on time, in writing, with supporting documents.

Do not ignore the letter. Missed deadlines invite assessments based on the CRA’s own estimates, which are rarely in your favor.

Frequently Asked Questions

What are an employer’s main CRA payroll responsibilities?

An employer must register for a CRA payroll account, calculate and withhold income tax, CPP contributions and EI premiums from each pay, remit those source deductions by the due date based on remitter type, file T4 slips and a T4 Summary at year-end, and keep payroll records for at least six years. Missing any of these steps can trigger penalties and interest, so a written payroll compliance checklist helps keep every obligation on schedule.

How do I calculate CPP and EI deductions for employees?

Start with gross pay for the pay period, then apply the current-year CPP contribution rate to pensionable earnings above the basic exemption, and the EI premium rate to insurable earnings up to the annual maximum. Use the CRA payroll deductions online calculator or T4127 formulas to confirm amounts.

When are payroll deductions due to the CRA?

Your CRA payroll remittance deadlines depend on your remitter type. Regular remitters with a monthly average withholding of $3,000 or less pay by the 15th of the following month. Threshold 1 remitters pay twice monthly, and Threshold 2 remitters pay four times monthly. New employers are usually regular remitters for the first 12 months. Always confirm your remitter type in your CRA online account, because late remittances attract penalties and interest.

How can I prepare for a CRA payroll audit?

CRA payroll audit preparation starts with clean records: keep payroll registers, T4 slips, remittance confirmations and employee contracts organized by year. Reconcile your payroll ledger to CRA statements monthly so discrepancies surface early. Before an audit, review worker classification for contractors, confirm taxable benefits are reported, and document your internal controls. If you find errors, correct them voluntarily before the auditor does, because voluntary disclosure can reduce penalties.
