My GST return does not match the cashbook – why? (New Zealand only)
- You could have your GST Return type set to “Invoice Basis”. This means that it will use the date of the Invoice rather than the date in the cashbook. We recommend that where possible companies use “Payments Basis” because it is a lot easier to use. This can be changed in the “Setup Wizard” on the “GST Setup” screen.
- Cashbook Complete calculates the GST from the cashbook exactly. All other figures in the GST return are then reverse-calculated from those figures. This can cause minor rounding errors. You do not need to worry about these small discrepancies. This is how the IRD wants us to calculate GST. The GST Detail Report (Page 2 of the GST Return) shows how these figures are all made up.
