Running a small business in Calgary? Bookkeeping may not be your favorite task — but avoiding common mistakes can save you thousands. At BS Bookkeeping & Tax Services, we help business owners like you stay audit-ready and stress-free.

Here are the top 5 bookkeeping mistakes to watch out for in 2025:

1. Mixing Business and Personal Finances

Why it matters: CRA expects clean records.
Fix it: Open a dedicated business bank account and use separate credit cards. Use accounting software like QuickBooks to track only business expenses.

2. Falling Behind on Recordkeeping

Why it matters: Delays can lead to missing deductions and CRA penalties.
Fix it: Set aside a weekly time block or hire a Calgary bookkeeper (like us) to manage it.

3. Ignoring GST/HST Deadlines

Why it matters: Late filings result in penalties and interest.
Fix it: Know your filing frequency and use QuickBooks reminders or our GST/HST filing services.

4. DIY Payroll Without Proper Setup

Why it matters: Payroll errors can trigger CRA audits.
Fix it: Use payroll software or let us handle your payroll processing in compliance with Alberta rules.

5. Not Backing Up Financial Data

Why it matters: A tech failure can mean lost tax records.
Fix it: Use cloud-based software with auto-backups or talk to us about secure digital bookkeeping options.

Bonus Tip: Not Getting Professional Help

Hiring a bookkeeper can actually save you money by optimizing tax deductions and ensuring CRA compliance.
