Top 10 bookkeeping mistakes to avoid.

In finance, meticulous bookkeeping is extremely essential. To help you steer clear of financial pitfalls, we’ve compiled a concise guide outlining the top 10 bookkeeping mistakes you should avoid. Whether you’re a business owner, accountant, or just looking to manage your personal finances more effectively, this list will prove invaluable in maintaining financial accuracy and stability.

01. Incorrect VAT Treatment

One of the most common errors is the incorrect application of VAT rules. This includes:

  1. Claiming VAT incorrectly on non-business expenses
  2. Not entering credit notes properly
  3. Claiming foreign VAT incorrectly The consequences include potential tax audits, fines, interest, and penalties from Revenue.

02. Not Performing Monthly Bank Reconciliations

Failing to reconcile accounting records with bank statements regularly can lead to major problems. Bank reconciliations identify discrepancies and help prevent duplicate payments or missing deposits.

03. Forgetting to Track Small Expenses

Small incidental expenses can add up over time. It’s important to capture all receipts, no matter how small, to ensure accurate financial reporting.

04. Giving Employees Too Much Access

While delegation is good, proper controls and oversight must be in place. Employees with unchecked access to accounting systems increase fraud risk.

05. Entering Owner’s Drawings as Wages

Recording owners’ drawings as a wage expense is incorrect. These are distributions of profit, not deductible salary payments.

06. Paying Net Wages Only to Wages Expense

Gross wage costs must be recorded separately from net wages paid to capture employer taxes correctly.

07. Recording Assets as Expenses

Assets over a certain value must be capitalized and depreciated, not expensed immediately. This avoids distorting financial statements.

08. Mixing Personal and Business Finances

Commingling personal and business transactions makes accurate reporting impossible. Separate bank accounts should be used.

09. Not Retaining Records for Required Timeframes

Financial records must be kept for Revenue’s required time periods of 6 years. Non-compliance can lead to penalties.

10. Lack of Communication with Bookkeeper

Bookkeeping requires collaboration. The bookkeeper must be informed of all relevant transactions.
