5 Costly Payroll Mistakes Ontario Small Businesses Make in 2025

Running payroll seems simple — until the CRA sends you a penalty notice or an employee complains.

Here are the 5 most common (and expensive) payroll mistakes we see every month with Toronto and GTA small businesses in 2025… and exactly how to fix them before they cost you thousands.

  1. Misclassifying Employees vs Independent Contractors
    → Mistake: Paying someone as a contractor when CRA considers them an employee.
    → Fix: Use the CRA’s free “Request a CPP/EI Ruling” tool or let us review it for you in under 24 hours.
  2. Forgetting to Remit Source Deductions on Time
    → Mistake: Missing the 15th-of-the-month deadline for CPP, EI, and tax remittances.
    → Fix: Set up automatic withdrawals or let us handle every remittance — 100% on time, guaranteed.
  3. Incorrect Vacation Pay Calculation
    → Mistake: Still paying 4% when the employee is now entitled to 6% after 5 years.
    → Fix: Run a quick vacation liability report in QuickBooks — we’ll do it for you in minutes.
  4. Missing or Late T4/T4A Slips (February 28 deadline)
    → Mistake: Last-minute rush leads to errors and $1,000+ penalties.
    → Fix: We prepare and e-file all T4/T4A slips for our clients by mid-February every year — zero stress.
  5. Ignoring 2025/2026 Rate Changes
    → Mistake: Still using 2024 CPP/EI rates in January → automatic under-remittance penalties.
    → Fix: One click updates everything. We do it for all clients before December 31.
