Avoid These Costly Errors and Keep Your Canadian Business Financially Healthy
Bookkeeping is the backbone of any successful business, yet it’s one of the most overlooked and misunderstood areasespecially among startups and growing corporations in Canada. From missed deductions to CRA audits, poor bookkeeping can lead to financial loss, legal risk, and growth limitations.
In this article, we’ll cover the most common bookkeeping mistakes corporations make, why they happen, and how you can avoid themparticularly if you’re an entrepreneur or small business owner in Canada.
1. Mixing Personal and Business Expenses
Why it’s a problem:
One of the most frequent and damaging mistakes is blending personal and business finances. This makes it nearly impossible to track deductible expenses, prepare accurate financial reports, or survive a CRA audit.
Solution:
Open a separate business bank account.
Use a dedicated business credit card.
Set up clear rules for reimbursements if personal funds are ever used for business.
2. Falling Behind on Bookkeeping Tasks
Why it’s a problem:
Delaying your bookkeeping results in lost receipts, missing transactions, and hours of catch-up work. Worse, it leads to late tax filings, penalties, and inaccurate reporting.
Solution:
Allocate a specific time weekly to review your finances.
Use cloud-based accounting software like QuickBooks Online or Wave Accounting.
Consider hiring a bookkeeper or outsourcing to a trusted provider like Cofianna.
3. Misclassifying Expenses
Why it’s a problem:
Incorrect expense categorization can lead to missed tax deductions or CRA red flags. For instance, treating capital assets as operational expenses affects your balance sheet and taxes.
Solution:
Review CRA’s guidelines on expense categories.
Work with a professional bookkeeper familiar with Canadian tax law.
Audit your expense reports quarterly.
4. Not Keeping Proper Receipts and Documentation
Why it’s a problem:
The CRA requires businesses to keep receipts and records for at least 6 years. Without documentation, you can’t prove business expenses or defend against an audit.
Solution:
Go digital: Use apps like Dext, Hubdoc, or Google Drive to scan and store receipts.
Keep all invoices, bank statements, and contracts organized by month and year.
5. DIY Bookkeeping Without Proper Training
Why it’s a problem:
Many founders try to handle bookkeeping themselves to save money. But without accounting knowledge, it’s easy to misreport taxes, overpay HST/GST, or underreport income.
Solution:
Take a basic course in bookkeeping (offered by CPA Canada or Small Business BC).
Outsource to a certified Canadian bookkeeper—you’ll save more in the long run.
6. Ignoring Payroll Compliance
Why it’s a problem:
If you have employees, failing to withhold the correct amounts for CPP, EI, and income tax can lead to CRA penalties and back payments.
Solution:
Use payroll software that calculates withholdings automatically.
File T4s and ROEs accurately and on time.
Stay updated with federal and provincial payroll regulations.
7. Forgetting to Reconcile Accounts
Why it’s a problem:
If your books don’t match your bank statements, it means your financials are off—this can lead to incorrect tax filings and cash flow mismanagement.
Solution:
Reconcile your bank, credit card, and loan accounts monthly.
Investigate and correct any discrepancies right away.
8. Failing to Track Sales Tax (GST/HST)
Why it’s a problem:
If you collect GST/HST and don’t track or remit it properly, you’re risking serious legal consequences.
Solution:
Register for a GST/HST number with the CRA when required.
Track tax collected and tax paid using accounting software.
File your returns on time (monthly, quarterly, or annually depending on your status).
9. Lack of Financial Reporting
Why it’s a problem:
Without regular reports like profit & loss, balance sheets, and cash flow statements, you’re flying blind. You can’t make informed decisions or secure funding.
Solution:
Generate reports monthly or quarterly.
Use them to track business health, identify trends, and set goals.
Review reports with your bookkeeper or accountant.

Why it’s a problem:

Solution:
Organize your books year-round.
Meet with your accountant in Q4 to plan tax strategies.
Prepare for deadlines: T2 Corporate Tax Return, GST/HST, T4s, and ROEs.
