The dependency insurance (1.40 %) applies to a base abated by a quarter of the SSM (692,83 €), with no ceiling, and is not income-tax deductible.
Notes on the calculation (2)
The employee tax credit (CIS) of 390,00 € per year is deducted from the withholding tax.
The CO2 tax credit (CI-CO2) of 140,40 € per year is also deducted from the withholding tax.
This is the monthly withholding (RTS); the annual assessment may adjust the result.
In Luxembourg your employer withholds income tax and social contributions from every payslip, so what lands in your account is already net. This calculator starts from the gross pay and deducts what is actually deducted.
The withholding tax (RTS) is charged on the taxable income by tax class — 1, 1a or 2 — after the deductible contributions and standard allowances; the employee tax credit then reduces the withholding. The calculator shows how it all fits together, using the rates and bands in force for 2026.

Why the tax class changes your net pay
The contract number is gross. What reaches your account is net — after contributions and the withholding tax, plus the employee tax credit.
Two employees with the same gross can take home different amounts once the tax class (single, single parent, married) is counted.
What the breakdown tells you
The distribution bar splits the gross into net pay, social contributions and the RTS tax, so you can see where each euro goes.
The employer cost sits separately — it rides on top of the gross and is never deducted from your net.

How the monthly withholding works
Social contributions come off the gross first; the taxable income is the gross minus the deductible contributions and the standard allowances (FFO/FDS).
The withholding tax (RTS) is charged on that base by tax class, the solidarity surcharge is folded in, and the employee tax credit is then deducted to reach the net.
