Record Keeping and GST Basics for Australian Small Businesses

Good record keeping is one of the least glamorous parts of running an Australian small business, but it is also one of the most important. Accurate records help you meet tax obligations, manage cash flow, make informed decisions and demonstrate your position if the Australian Taxation Office (ATO) asks questions. This guide covers the essentials of record keeping and GST for small business owners.

Why good record keeping matters

Records are not just for tax time. They show you which products are profitable, which customers pay on time, and where your expenses are growing. Without them, you are guessing. With them, you can plan with confidence.

The ATO requires businesses to keep records that explain all transactions and are written in English. Records can be electronic or paper, but they must be easy to access and understand. Poor records can lead to penalties if you cannot substantiate your claims.

What records to keep

At a minimum, keep records of income and expenses, bank statements, tax invoices, receipts, contracts and payroll information. If you sell online, keep platform reports and payment gateway statements. If you use contractors, keep their invoices and any agreements, including details relevant to an on-hire labour agreement if applicable.

• Income records: Sales, fees, interest and other revenue.
• Expense records: Purchases, rent, utilities, wages, superannuation and professional fees.
• Asset records: Equipment purchases, depreciation and disposal.
• Tax records: BAS statements, tax returns, GST calculations and ATO correspondence.

If you finance a vehicle or equipment, keep the loan documents and repayment schedule. A Car Loan World Australia Review can help you understand financing options, but your own records should always reflect the actual agreement.

GST basics for small business

GST is a broad-based tax on most goods and services sold in Australia. If your business turnover reaches the GST registration threshold, you must register for GST. Once registered, you generally charge GST on your sales and can claim credits for GST paid on business purchases.

You must issue tax invoices for sales above a certain value, and you need valid tax invoices from suppliers to claim GST credits. Your business activity statement (BAS) reports your GST obligations to the ATO, usually quarterly or monthly. Keeping GST records separate from other accounting makes BAS preparation much simpler.

Some sales are GST-free or input-taxed, such as certain health services, education and exports. If you are unsure how GST applies to your products, seek advice from a registered tax agent.

Record keeping systems and digital tools

Cloud accounting software can automate much of your record keeping. You can link bank accounts, scan receipts and generate reports. Many tools also calculate GST and prepare BAS figures. Choose a system that suits your business size and industry, and make sure you back up your data.

If you work from a shared or virtual office, keep your business records secure and ensure your business address is up to date with the ATO and ASIC. This helps you receive important correspondence and stay compliant.

How long to keep records

Generally, you must keep records for five years from the date you lodge your tax return or the date of the transaction, whichever is later. Some records, such as those relating to assets, may need to be kept longer. If you are involved in a dispute or audit, keep records until the matter is resolved.

Store records securely, whether digitally or physically. If you use cloud software, check that your provider backs up data and allows you to export it if you change systems.

Common record keeping mistakes

• Mixing personal and business expenses.
• Failing to keep receipts for small purchases.
• Recording income only when it hits the bank, rather than when it is earned.
• Not reconciling bank accounts regularly.
• Leaving BAS preparation to the last minute.

Set aside time each week or month to update your records. A little routine maintenance prevents a large backlog and keeps you ready for tax time.
