How to Reconcile GST Amounts Collected
Step-by-Step GST Reconciliation
Reconciling your GST ensures the amount you report on your BAS matches what was actually collected. Here's how to do it using Build Stability.
1. Generate the GST Report
Go to Dashboard > Reports > GST Report. Select the BAS period (e.g. "This Quarter" for quarterly BAS, or use Custom Range for monthly BAS). Click Generate Report.
2. Check the Summary Figures
- GST Collected = total GST to report on your BAS (label 1A) - Total Sales (inc. tax) = gross revenue including GST (label G1) - Net Sales (exc. tax) = Total Sales minus GST Collected — this should match your bank deposits minus any Stripe fees
3. Verify Against the Invoice Table
Scroll down to the "Invoices in Period" table. Each invoice shows its GST amount individually. Add them up — the total should match the GST Collected figure in the summary card above. If it doesn't match, check for invoices that may have been finalised in one period but paid in another.
4. Cross-Check with Stripe
Log in to your Stripe Dashboard and check the Payments tab for the same period. The total payments received should match your Total Sales figure. Small differences may be due to Stripe processing fees (which are separate from GST).
5. Download CSV for Your Accountant
Click Download CSV to export all invoice data. The CSV includes Invoice Number, Date, Customer, Total, GST, Net, and Type — ready to import into Xero, MYOB, or any spreadsheet.
6. Common Reconciliation Issues
- GST shows $0 on an invoice: The service was created before GST was enabled, or the client's payment method didn't trigger automatic tax. Check your GST registration date. - Invoice missing from the report: The report only includes paid invoices. Unpaid or draft invoices are excluded. Check the Invoice History report for all statuses. - Totals don't match Stripe exactly: Stripe fees are deducted from payouts but are not reflected in invoice totals. Your GST obligation is based on the full invoice amount, not the net payout. - Mixed periods: If a client paid on the last day of the quarter, check whether the invoice's finalised date falls within your selected period.
