Bookkeeping is the backbone of every successful business, yet it’s one of the areas where small business owners make the most costly mistakes. Whether it’s mixing personal and business expenses or falling behind on reconciliations, these errors can lead to inaccurate financial reporting, missed tax deductions, and even CRA audits.
At Padgett Business Services, we’ve seen it all. Over our decades of experience helping Canadian entrepreneurs, we’ve identified the most common bookkeeping mistakes—and more importantly, how to fix them. This guide will help you avoid these pitfalls and keep your books in order.
Mistake #1: Mixing Personal and Business Finances
The Problem
One of the most common mistakes small business owners make is using the same bank account and credit card for both personal and business expenses. This creates a tangled mess that makes it nearly impossible to accurately track business income and expenses.
Why It’s Dangerous
- CRA Scrutiny: Co-mingling funds is a red flag for the CRA, and can increases the risk of an unfavourable audit or review.
- Inaccurate Financial Information: You won’t have a clear picture of your business’ profitability.
- Loan Complications: Lenders require clean financial information, and mixed accounts make it difficult to demonstrate your business’s financial health.
The Fix
Open a dedicated business bank account and business credit card immediately. Transfer any personal expenses that were mistakenly charged to your business account back to your personal account, and vice versa. Going forward, use your business accounts exclusively for business transactions.
Mistake #2: Not Keeping Receipts and Documentation
The Problem
Many business owners fail to keep receipts for their expenses, thinking they can rely on bank statements alone. However, the CRA requires supporting documentation for all claimed deductions.
Why It’s Dangerous
- Lost Deductions: Without receipts, you cannot claim expenses or input tax credits for sales tax, even if they appear on your bank statement.
- Audit Risk: If the CRA audits you and you cannot provide receipts, your deductions will be disallowed, and you may face penalties.
The Fix
Implement a system for capturing and storing receipts immediately. Consider using receipt-tracking apps like Dext or Hubdoc, which allow you to photograph receipts with your phone and automatically categorize them. Alternatively, create a dedicated folder (physical or digital) for all receipts and file them regularly.
Mistake #3: Falling Behind on Bookkeeping
The Problem
It’s easy to let bookkeeping slide when you’re busy running your business. Before you know it, months have passed, and you’re facing a mountain of unrecorded transactions.
Why It’s Dangerous
- Increased Errors: The longer you wait, the harder it is to remember what transactions were for, leading to misclassifications.
- Cash Flow Problems: Without up-to-date books, you won’t know if you’re making or losing money.
- Year-End Stress: Catching up on months of bookkeeping at tax time is stressful and time-consuming.
The Fix
Set a recurring weekly or bi-weekly appointment with yourself to update your books. Even dedicating just one hour per week can prevent you from falling behind. Better yet, consider outsourcing your bookkeeping to a professional so you can focus on growing your business.
Mistake #4: Misclassifying Expenses
The Problem
Not all expenses are treated the same for tax purposes. For example, capital assets must be depreciated over time, while operating expenses can be fully deducted in the year they are incurred. Misclassifying expenses can lead to incorrect tax filings.
Why It’s Dangerous
- Tax Errors: Incorrect classifications can result in overpaying or underpaying taxes.
- CRA Audits: Consistent misclassifications can trigger an audit.
The Fix
Familiarize yourself with the CRA’s guidelines on expense classifications, or work with an accountant to ensure your chart of accounts is set up correctly. When in doubt, ask your accountant before categorizing an expense.
Mistake #5: Not Reconciling Bank Accounts
The Problem
Bank reconciliation is the process of matching your bookkeeping records to your bank statements. Many small business owners skip this step, assuming their books are accurate if the numbers are close.
Why It’s Dangerous
- Undetected Errors: Reconciliation catches data entry errors, duplicate transactions, and fraudulent charges.
- Inaccurate Financial Statements: Your income statement and balance sheet maybe wrong if your books don’t match your bank.
The Fix
Reconcile your bank accounts and credit cards monthly. Most accounting software makes this process straightforward. If you find discrepancies, investigate and correct them immediately.
Mistake #6: Ignoring Small Transactions
The Problem
Small expenses like coffee, parking, or office supplies may seem insignificant, but they add up over time. Many business owners don’t bother tracking them.
Why It’s Dangerous
- Lost Deductions: Those small expenses can add up to hundreds or even thousands of dollars in lost deductions.
- Incomplete Financial Picture: Ignoring small transactions means your financial statements don’t reflect the true cost of running your business.
The Fix
Track every business expense, no matter how small. Use a petty cash system or a dedicated business credit card to make tracking easier.
Mistake #7: Not Tracking Mileage
The Problem
If you use your vehicle for business, you can deduct a portion of your vehicle expenses. However, the CRA requires a detailed mileage log to support your claim.
Why It’s Dangerous
- Significant Lost Deduction: Vehicle expenses can be one of the largest deductions for small businesses.
- CRA Rejection: Without a mileage log, the CRA will disallow your vehicle expense claim.
The Fix
Keep a mileage log in your vehicle and record every business trip, including the date, destination, purpose, and kilometres driven. Alternatively, use a mileage-tracking app like MileIQ to automate the process.
Mistake #8: Incorrect GST/HST Treatment
The Problem
Businesses registered for GST/HST must charge the correct amount on sales and can claim Input Tax Credits (ITCs) on eligible purchases. Errors in GST/HST accounting are common and can be costly.
Why It’s Dangerous
- CRA Penalties: Incorrect GST/HST filings can result in penalties and interest.
- Lost ITCs: Failing to claim ITCs means you’re paying more tax than necessary.
The Fix
Ensure your accounting software is set up to correctly calculate GST/HST on sales and purchases. Review your GST/HST returns before filing, and consult with an accountant if you’re unsure about any transactions.
Mistake #9: Not Backing Up Your Data
The Problem
Many small business owners rely solely on their computer or cloud-based software without implementing a backup strategy. If your computer crashes or your software provider experiences a data loss, you could lose everything.
Why It’s Dangerous
- Total Data Loss: Without backups, you could lose years of financial records.
- CRA Compliance Issues: The CRA requires you to keep records for six years from the end of the last tax year. If you lose your data, you won’t be able to comply.
The Fix
If you use cloud-based accounting software, your data is likely backed up automatically. However, it’s still a good idea to export your data regularly and store it in a separate location. If you use desktop software, set up automatic backups to an external hard drive or cloud storage.
Mistake #10: Trying to Do It All Yourself
The Problem
Many small business owners try to handle their own bookkeeping to save money. While this may work in the early stages, it often leads to errors, missed deductions, and wasted time.
Why It’s Dangerous
- Time Drain: Bookkeeping takes time away from revenue-generating activities.
- Costly Errors: Mistakes can cost you far more than the price of hiring a professional.
- Missed Opportunities: A professional can identify tax-saving strategies you might miss.
The Fix
Recognize when it’s time to outsource. If bookkeeping is taking up more than a few hours per week, or if you’re constantly stressed about it, it’s time to bring in a professional.
