Avoid these costly errors
Running a small business comes with plenty of responsibilities, and accounting can easily become something that gets pushed aside when things get busy. However, small accounting mistakes can quickly become expensive when they affect cash flow, GST reporting, payroll, tax deductions, or business decisions.
The most damaging accounting mistakes are often not dramatic. They are small, routine issues that are repeated over time until the business no longer has a clear and reliable picture of its financial position.
Here are some of the most common accounting mistakes small businesses should avoid.
Mixing business and personal expenses
One of the most common mistakes is using the same bank account or credit card for both personal and business transactions. This can make bookkeeping more time consuming and increases the risk of personal expenses being incorrectly claimed as business expenses. It can also result in legitimate business expenses being overlooked.
Keeping business and personal finances separate makes it easier to maintain accurate records and explain transactions to your accountant, lender, investor, or the ATO if required.
Not reconciling accounts regularly
Bank reconciliation is a simple but important accounting control that is often overlooked when business owners are busy. Without regular reconciliations, duplicate payments, missing deposits, incorrect supplier allocations, and uncleared transactions can go unnoticed.
Regular reconciliation helps confirm that the transactions recorded in your accounting software match your actual bank activity. This provides a more reliable foundation for BAS preparation, tax returns, management reporting, and cash-flow planning.
Weak GST and BAS processes
GST and BAS errors can occur when transactions are incorrectly coded, GST credits are claimed without appropriate records, sales are reported in the wrong period, or GST-free and taxable supplies are treated incorrectly.
BAS preparation should not be treated as a last minute task. Business.gov.au notes that BAS may cover obligations such as GST, PAYG withholding, PAYG instalments, FBT instalments, luxury car tax, and wine equalisation tax, depending on the business’s registrations and circumstances.
A structured BAS review process can help ensure the correct sections are completed and that reported figures reconcile with the underlying accounting records.
Ignoring Payroll, Superannuation and PAYG Obligations
Payroll is another area where small errors can create significant compliance issues and affect employee trust.
Businesses with employees need to ensure wages, PAYG withholding, superannuation and reporting obligations are processed accurately and on time.
Payroll should also be reconciled against the accounting records so that outstanding tax and superannuation liabilities are accurately reflected.
A consistent payroll process can help support accurate Single Touch Payroll reporting and end-of-financial-year payroll finalisation.
