Hello Gnau,
If you are reporting the final figures in July for the financial year, then we can guide you on where to enter information into the payroll system. This guide on EOFY reporting may be useful in showing where to enter in RFBA amounts in the payroll system.
However, if you are unsure which date range to report to the ATO, you will need to speak to them directly, or to your accountant to determine this.
