How does the lower deposit into social security affect the event of salary conversion?
By saving on social security, your net salary increases significantly. At the same time, the lower burden reduces the amount you pay into pension, health, long-term care and unemployment insurance. This has no effect on the nursing care and health insurance, since these work according to the parity principle (equal benefits for all regardless of how much has been paid in). On the unemployment and pension insurance, the lower payment has a financial impact.
