Pre-lodgement checklist: gather everything first
Start by confirming your reporting period and whether your BAS is for monthly or quarterly activity. Then collect your sales records, including invoices, receipts, and summary reports from your point-of-sale or accounting software. If you claim bas lodgement GST credits, gather purchase invoices and ensure they’re correctly dated and attributable to your business activities. This step reduces rework and helps you avoid missing figures that can cause lodgement delays.
Next, review your bank statements and reconcile them against your bookkeeping reports. Look for unusual transactions such as mixed personal and business expenses, refunds, chargebacks, or transfers that may need classification changes. If you use payroll, confirm the amounts related to wages and PAYG withholding are supported by payroll reports, not estimates.
GST and reporting controls: accuracy over assumptions
Before you submit, verify GST on sales by comparing your totals to the income entries in your general ledger. Check whether any sales are exempt, GST-free, or outside the scope of GST, because these categories affect how amounts are reported. If you’ve books and balance had cash basis adjustments, confirm the method used in your records matches the figures you plan to report. When numbers don’t align, trace back to the source document rather than forcing the totals to fit.
For GST credits, confirm the eligibility of each expense category you’re claiming. Ensure you can substantiate the business purpose of purchases and that invoices meet the required details for claiming input tax credits. If you’ve made adjustments for partial payments, deposits, or credits from suppliers, confirm these are reflected consistently across your records. This is where a structured checklist approach prevents common mistakes that can trigger follow-up questions from the ATO.
Compliance checks: review amounts, calculations, and responsibilities
Use a final review checklist to validate that each section of the BAS form has been completed logically and consistently. Cross-check totals, tax codes, and calculated GST amounts with your accounting reports, such as profit and loss and balance sheet summaries. Confirm that any PAYG withholding and other components are included if they apply to your business. If you’re unsure about a figure, document the reason and correct the underlying entry before lodgement.
Also confirm your reporting obligations and lodgement responsibilities so you’re not submitting information that conflicts with your business setup. If you’ve recently changed your turnover, accounting method, or business structure, ensure your records still reflect those changes accurately. Consider whether you’ve taken over bookkeeping midstream, as prior periods may contain carry-forward balances that need verification. A careful compliance check can help you submit confidently and avoid amendments that consume additional time and cost.
