How does Luxembourg payroll tax work in 2026?

The pension rise is the 2026 story

The pension reform law of 18 December 2025 lifted the global pension rate from 24% to 25.5%. Each party, the State, the employee and the employer, moved from 8% to 8.5%. For any employer running Luxembourg payroll this is a real cost step from January 2026, on every salary, with no ceiling relief at the rates shown here.

The Employer Mutuality charge

One employer-only charge sits outside the table because it has no single rate. The Employer Mutuality (Mutualité des employeurs) reimburses part of the salary an employer continues to pay during sickness. Its rate is set by the employer's absenteeism class, so it changes from one company to the next rather than being a fixed percentage. We model your actual class in the employer-cost figure rather than quoting a placeholder.

Pension and health, matched

Pension and health are shared evenly between the two sides. The employee pays pension at 8.5% and the employer matches it. The same holds for health in-kind at 2.8% and health cash at 0.25%.

Dependency cover is the employee's alone

Dependency insurance (assurance dépendance) funds long-term care. The employee pays 1.4% and the employer pays nothing toward it. It applies after a monthly deduction set in the social security code, so it does not start from the first euro of pay. Income tax is then worked out on what remains after these contributions.

Luxembourg taxes employment income at source through the rate table (barème) set by the income tax law. The 2025 table remains in force for 2026, with no new band rates enacted. Rates rise step by step from a zero band on the lowest pay to the top marginal rate.

The table above shows the shape, not every band. The full scale moves in small steps: 0%, 8%, 9%, then on through the teens and twenties, reaching 39% across a wide high-earner band before the final climb to 42%. Where each band starts is set by the rate table and by the employee's tax class, which depends on marital and family status.

Tax class changes the take-home, not the rate

The rate table is the same for everyone, but the tax class shifts where the bands bite. A single employee, a married couple and a single parent each sit in a different class, so two people on the same salary can take home different amounts. Teamed applies the correct class on every run so the deduction at source is right the first time, not corrected at year end.

Luxembourg payroll runs on a monthly cycle. The employer must pay the salary by the last calendar day of the month it covers, and must hand the employee a detailed written payslip with that payment (Code du travail, art. L.125-7).

• Social contributions to the CCSS, which bills the employer monthly for both the employer and employee shares
• Income tax withheld at source declared and paid to the Administration des contributions directes (ACD)
• Payslip issued to each employee every month, showing the gross, each contribution, the tax withheld, and the net

The CCSS is the single door for social security. It registers the employee, collects every fund in one statement, and chases late payment. Income tax sits on a separate track with the ACD. Getting both filed and paid on the monthly rhythm is what keeps a Luxembourg payroll clean. Miss the CCSS schedule and interest and recovery action follow on the unpaid contributions.

1. Collect pay data

   Gather salary, hours, bonuses and any taxable benefits for the month before the run closes.

2. Apply social contributions

   Work out the employee pension, health and dependency deductions, then the employer pension, health, accident and Mutuality shares.

3. Withhold income tax

   Apply the rate table at the employee's tax class to the pay left after contributions, and withhold the tax at source.

4. Issue the payslip

   Hand each employee a detailed payslip showing gross, every contribution, the tax withheld and the net pay.

5. Remit and declare

   Pay the CCSS statement for social contributions and declare the withheld tax to the ACD on the monthly rhythm.

Pension is shared evenly. The employer pays 8.5% and the employee pays 8.5%, with the State adding the same share on top. Together the three sides now fund a global pension rate of 25.5%, up from 24% before January 2026.

Health and dependency sit beside pension

Health insurance is split into in-kind and cash benefits. In-kind cover is 2.8% from each side. Cash cover, which funds sick pay, is 0.25% from each side. Dependency insurance, for long-term care, is 1.4% from the employee only.

What the employer carries alone

Accident insurance at 0.70% and occupational health at 0.14% fall on the employer with no employee match. The Employer Mutuality charge, which varies by absenteeism class, is also employer only. There is no statutory pension cap shown in these rates, so the pension rise lands on the full salary.

Real HR and legal experts run your Luxembourg hires, from the first contract through every monthly CCSS statement and tax-at-source declaration. An actual person, not a chatbot or a pooled queue. There is no setup fee and no exit fee. Employer cost passes through at cost, itemised on every invoice, so you see pension, health, accident and the Employer Mutuality as separate lines, never one blended number.

EOR payroll, contractor onboarding and entity setup all live on one platform. A Luxembourg contractor who moves onto payroll keeps their record. That same employee can graduate from EOR to your own Luxembourg entity without switching systems. EOR is the right model for a first Luxembourg hire, until it isn't, and we tell you when the numbers turn.
