The current design stores Marital Status only as a current value, without an effective-from/to date.
This creates a payroll gap in countries where a change in marital status affects tax treatment.
Example - Switzerland:
An employee is Single and gets married on 15 May. For Swiss withholding tax, a change in civil status can change the applicable tax tariff.
If IFS only stores Marital Status = Married, it cannot determine when the employee became married or which status applied to a particular payroll period.
Proposed Design Change:
Marital Status should have validity period.
Effective dating supports payroll calculations in countries where marital-status changes have statutory payroll/tax consequences.
