GST Reconciliation

Common causes for misalignment in balances

  • Transaction being entered or changed for a period after the BAS was submitted.
  • Transaction being converted to Tax Invoices from Sales Orders for a date in the BAS period after the BAS was submitted.
  • As at 30 June 2021 businesses generally won’t have calculated and entered a BAS Purchase Invoice for the final remittance for the financial year so accounting firms often enter those GST and PAYG liabilities as a journal at year end.
  • Accounting firms adjusting GST via journals to allow for special tax treatment regarding GST. e.g. upfront claims deemed allowable on an asset purchase that is being paid for over time.
  • Not locking accounting file at month end and non-accounting staff changing a transaction. e.g. editing Sale, adding Expense claim.
  • Transactions or Journals coding to GST liability accounts incorrectly.

Tasks to check your BAS at Financial Year End

Cash Basis

  • Make sure you BAS Report for each quarter or month hasn’t changed compared to what you filed.
  • If it has changed you may need to adjust your GST in your next BAS remittance.
  • Run you final BAS for the financial year and add that as a Purchase as at 30 June if you want this captured in that same financial year. Often accountants ask customers to do an adjusting Journal for GST to achieve this result.
  • Outstanding creditors and debtors will have some GST on them. You need to calculate these amounts.

Result: GST = Last BAS GST + Debtors GST – Creditors GST

Accrual Basis

  • Make sure you BAS Report for each quarter or month hasn’t changed compared to what you filed.
  • If it has changed you may need to adjust your GST in your next BAS remittance.
  • Check the GST Payable in your final BAS matches the Balance Sheet Saasu GST Payable*.

Result: GST = Last BAS GST

* GST Paybale in Saasu is the Net of two accounts being Liability: Tax Collected from SalesAsset: Tax Paid on Purchases
