A pre-BAS GST check means reviewing bills for wrong tax codes, missing tax invoices and suppliers not registered for GST before you claim credits.
Before you start
- Extended Tax Reporting ticked and period type set in Company Details > Accounting Data
- BAS codes defined (Administration > Setup > Financials > Tax > BAS Code Definitions)
The SAP B1 way
Where to find it: Administration > System Initialization > Company Details > Accounting Data (tick Extended Tax Reporting); Financials > Financial Reports > Accounting > Tax > BAS Report Generation
- Tick Extended Tax Reporting and set the Period Type for Report Generation in Company Details.
- Check or add BAS codes in BAS Code Definitions.
- Open BAS Report Generation. Choose Original, Replacement or Adjusted and the year and period.
- Review the documents and transactions grouped by BAS code. Edit manual codes.
- Choose Add to save the report.
Limits in SAP B1
- Other Australia tax reports in the help: Tax Report, Withholding Tax Report, Tax Reconciliation Report, Tax Declaration Box Report.
The Pulsify way
- Forward bills to Pulsify through the period.
- Pulsify sets a GST code on each line from the rate printed on that line.
- Pulsify flags a supplier ABN that is not registered for GST when GST is charged.
- Review flags before approval, so fewer errors reach SAP B1.
Pulsify connects to SAP B1. We set up the connection for you.
What Pulsify does not do here
- Pulsify does not lodge or prepare your BAS.
- It does not check bills already in SAP B1.
Common mistakes
- Running BAS Report Generation before Extended Tax Reporting is ticked.
- Not defining BAS codes, so rows have nowhere to group.
