How we calculate Luxembourg net pay

The calculator follows the payslip of a full-time private-sector employee, month by month, because the social minimum wage and the contribution ceiling move with wage indexation (in June 2026) and the tax credits are trued up in December. Sources: the scales, formulas and circulars of the direct tax office (Administration des contributions directes, ACD) and the social parameters of the social security centre (CCSS) — see data sources.

Social security contributions

Employees pay 8.50% pension insurance (8.00% in 2025), 2.80% for healthcare and 0.25% for cash sickness benefits, on gross pay up to five times the social minimum wage: €13,518.68 a month until May and €13,856.63 from June 2026. The ceiling applies to the year to date and is trued up every month. Long-term care insurance (1.40%) applies to all pay with no ceiling, after an allowance of a quarter of the social minimum wage (€692.83 a month). Your salary stays the same all year: the automatic indexation of wages is not applied to the amount you enter.

Income tax withholding

The base is "semi-net" pay: gross minus pension and health contributions; the long-term care contribution is not deductible. It is rounded down to €5, then the tax office formula for the tax class (rate × amount − deduction) gives the withholding, rounded down to 10 cents; below €1 nothing is withheld. The flat-rate allowances for work expenses (€540) and special expenses (€480) are built into the scale, whose rates run from 0% to 42%. The scale set for 2025 still applies in 2026. Class 1: single people; class 1a: single parents, widowed people and taxpayers aged 64 or over; class 2: married couples and partners taxed jointly.

Employment fund surcharge

Withholding is increased by 7% for the employment fund; the part of the tax relating to taxable income above €150,000 a year (€300,000 in class 2) is increased by 9%. The surcharge is rounded down to 10 cents.

13th month

A 13th month is a non-periodic payment: it carries pension and healthcare contributions (not the 0.25% for cash benefits) within the unused annual ceiling, and long-term care on the month's total. Tax comes from the table of rates for non-periodic payments, set by regular annual pay; above €60,000 of regular pay, or for €5,600 or more, withholding is the difference in annual tax. The minimum wage credit ignores non-periodic payments as long as they stay within €3,000 a year.

Tax credits

The employee credit (CIS: €600 a year on €11,266 to €40,000 gross, tapering to €80,000) and the CO2 credit (€216, €192 in 2025) are worked out on expected annual gross pay, divided by 12, rounded up to the cent and trued up with December's salary. The minimum wage credit (CISSM) is €81 a month on full-time gross pay of €1,800 to €3,000, tapering to €3,600. The single-parent credit (CIM: €3,504 a year, tapering between €60,000 and €105,000 of adjusted taxable income, at least €750) needs a class 1a tax card marked CIM. Credits are paid even when there is no tax to pay.

Employer cost

Employers pay 8.50% pension, 2.80% + 0.25% health, 0.65% accident insurance (bonus-malus factor 1.00), 0.14% occupational health and the employers' mutual insurance by absenteeism class (0.23% · 0.95% · 1.56% · 2.66%), all on pay up to the ceiling. In the private sector family benefits are funded by the state.
