Pre-lodgement checklist: set up your records for accuracy
Before you submit anything, start by confirming your bookkeeping is complete and reconciled. Gather your sales records, purchase invoices, bank statements, and any account activity that feeds into your reports. If transactions are missing bas lodgement or coded incorrectly, your reporting figures can drift and create problems that take time to fix. Treat this as an information quality check, not just an admin step.
Next, verify that your GST details and reporting basis are correct for your business. This includes ensuring you’ve applied the right GST treatment to sales and purchases, such as taxable, GST-free, or input taxed categories. Review your chart of accounts so the bookkeeping categories match the way you report. If you use multiple bank accounts or payment platforms, reconcile each one so totals align with your general ledger.
Data validation checklist: review GST amounts and supporting documents
Now move to a document-level review that supports every figure you plan to report. Pull up sales summaries and ensure they reconcile with deposits and invoiced amounts. For expenses, check that invoices are valid, include required details, small business bookkeeping and are entered under the correct GST categories. If you claim GST credits, confirm the purchase was made for your business activities and that the records are retained in an organized way.
After that, check adjustments that commonly cause mismatches. Examples include corrections for cancelled sales, discounts, refunds, and credit notes, as well as GST on assets or reimbursements. Make sure your bookkeeping reflects these changes and that they flow through to the numbers used for the statement. Also confirm that any rounding or journal entries were applied consistently so the totals don’t shift between reports.
Filing preparation checklist: confirm the essentials for
With figures validated, confirm the internal controls you rely on for consistent. Ensure the BAS figures are prepared from the latest accounts and that the period being reported is clearly identified in your workflow. Check that your contact and business details are up to date, including the registered business name and relevant identifiers used for lodgement. If you outsource bookkeeping, verify the file version and ensure the final numbers are the ones approved for submission.
Then review your calculation method and confirm the GST reporting settings you use in your system. Some businesses use accrual-style tracking, while others rely on different approaches for reporting; your statements must match your chosen method. Confirm that your software setup captures all required components and that any imported data is mapped correctly. Finally, perform a “cross-check” by comparing your BAS-related totals against management reports like profit and loss and balance sheet movements.
