😎 I don´t see the WF parameter in BSI script, why?

The parameter WF: 0,0 is not being sent in all scenarios in the BSI script, as BSI considers it as WF: 0,0 if there isn´t this parameter in the BSI script. Parameter WF: 1,1 or 1,2 is always being sent in case the employee has an IT0210 record that follows the new W-4 Form Model for year 2020.

For further information, please check the KBA:
2985123 - The Parameter WF on the BSI Interface

9) Parameter WF is not in the correct line in BSI interface in TaxFactory 11.0?

There is a change in TaxFactory 11.0 cyclic B the parameter WF should be placed in other line in BSI script. This change has been delivered in the W-4 notes for States, after you apply the notes this parameter will be send in the line BSI expects to do the calculation for FED taxes.

The change in the parameter has been delivered in SAP notes:
2895426 – Prerequisite objects for SAP Note 2878657
2878657 – 2020 State Withholding Tax Calculation – Based on the State (or State-equivalent) Withholding Certificate (SAP_HR) – Phase I

After SAP notes 2888094 TAX: Lock-in letters override for W-4 exempt and 2880846 TAX: Lock-in letters not overriding New W-4 is now considering the values of IT0161 and now the system is calculating more tax, which is expected.
