Common Payroll Pitfalls (and How Accountants & Bookkeepers Can Help Clients Avoid Them)

It’s mid-December. Holiday bonuses are being calculated, stat holidays are around the corner, and T4 season is just weeks away. For small businesses, this is when payroll mistakes are most likely to pile up. And when they do, guess who gets the panicked call? 

The truth is, nearly 1 in 4 small businesses get payroll wrong — and the fallout isn’t just frustration. Errors can mean CRA penalties, unhappy employees, or hours of rework for you. 

The good news? These problems are predictable — and preventable. 

The 5 Payroll Pitfalls That Cause the Most Pain 

1. Late or missed CRA remittances 

• The problem: Owners forget, or submission is left to the last minute.
• The cost: Penalties can add up to 10% of the amount owing.
• How you help: Set up schedules and monitoring so nothing slips.
• How Powerpay helps: Remittances are auto-scheduled, so deadlines aren’t missed.

2. Misclassifying employees and contractors 

• The problem: Treating a worker as a contractor rather than an employee.
• The cost: CRA audits, back pay, and compliance risk.
• How you help: Guide clients through classification rules.
• How Powerpay helps: Setup employees deductions an withholdings properly from day one.

3. Incorrect statutory holiday pay 

• The problem: Every province has its own rules. Manual tracking almost guarantees errors.
• The cost: Employee disputes, legal claims, and client frustration.
• How you help: Put processes in place to calculate correctly.
• How Powerpay helps: Statutory holiday tracking built in average calulations for Alberta, British Columbia, Ontario and Quebec.

4. Year-end slips that don’t reconcile 

• The problem: January hits and T4s or RL-1s don’t line up with payroll totals.
• The cost: Hours of rework, delays, and stress for everyone.
• How you help: Proactive reconciliation before year-end.
• How Powerpay helps: T4, T4A, and RL-1 slips that align with CRA and RO requirements.

5. Poor recordkeeping 

• The problem: Missing employee files, inconsistent data, or no backup plan.
• The cost: Compliance gaps during audits and wasted time chasing paperwork.
• How you help: Standardize processes and retention policies.
• How Powerpay helps: Secure record storage built in.

Why This Matters Right Now

By getting ahead of these pitfalls now, you protect your clients — and save yourself from messy cleanup in the new year. The payoff for you and your clients is simple: 

• Clients have fewer errors, fewer penalties, happier employees.
