Payroll is the monthly process by which an employer prepares each employee's payslip, computes net pay after social contributions and wage-tax withholding, declares remuneration to the CCSS and remits the withholding to the ACD. In Luxembourg it embeds tax classes, the wage index and the social minimum wage.
Labour Code and Social Security Code; affiliation and filings with the Joint Social Security Centre (CCSS); wage-tax withholding on salaries and dematerialised tax-deduction forms (ACD); labour-law oversight by the Labour and Mines Inspectorate (ITM).
Key takeaway
- Every employer must declare each new hire to the CCSS within 8 days of the start of employment and issue a monthly payslip.
- Net pay is computed after social contributions (employee and employer share) and wage-tax withholding based on the tax class (1, 1a or 2).
- Salaries are indexed: the wage index automatically adjusts pay to price developments.
- Outsourced payroll starts at EUR 20 excl. VAT per payslip, with no software to buy.

What are payroll services in Luxembourg?
Payroll covers everything that turns an agreed gross salary into net pay that is paid and declared: computing social contributions (employee and employer share), applying the wage-tax withholding based on the tax class, issuing the payslip, declaring remuneration to the CCSS and remitting the withholding to the ACD.
Outsourcing payroll means entrusting this monthly cycle to a licensed accountant: no software to buy, no rate errors, compliant payslips and on-time filings, with a single contact who also handles your accounting in Luxembourg.
Payroll and HR administration: the social secretariat
In Luxembourg, SMEs and craft businesses often call the provider that runs payroll and HR administration their social secretariat (secrétariat social). It covers the same cycle as outsourced payroll, extended to the formalities that surround each employee.
In practice it covers employer and employee affiliation with the CCSS, monthly payslips, wage tax remitted to the ACD, entry and exit declarations, leave and sickness tracking, indexation and standard employment contracts. Payroll is then reconciled each month with your accounting in Luxembourg, with no double keying between two providers.
CCSS affiliation and filings
Within 8 days of the start of employment, the employer declares the new hire to the Joint Social Security Centre (CCSS), which manages affiliation and contribution calls; beyond 30 days late, the CCSS may fine EUR 50 per month of delay, capped at EUR 2,500. Each month, remuneration is declared and contributions (health, pension, dependency, accident, employers' mutuality) are computed on the contributory base.
We handle entry and exit declarations, sickness and accidents, monthly filings and CCSS statements, aligned with your accounting and cash flow. Staff costs for the financial year then flow straight into the annual accounts filed with the RCS.
Payslip: content and obligations
The payslip details gross salary, employee social contributions, wage-tax withholding, any benefits in kind and net pay. It must be issued monthly and retained. An error in tax class, index or base feeds directly into the employee's net pay and the filings.
We produce clear, compliant payslips, available to your employees through a dedicated portal, with the annual certificates they need for their tax return.
Gross to net: contributions, tax classes and index
Moving from gross to net depends on three elements: social contributions (employee share), the wage-tax withholding set by the tax class (1, 1a or 2, depending on family situation), and the index. The wage index automatically adjusts salaries to price developments: each time an index bracket is crossed, salaries are revalued.
Rates and thresholds follow the schedule in force (CCSS, ACD) and indexation. We apply up-to-date parameters and explain net pay to your employees, cross-border workers included.
Payroll for craft and construction businesses
In crafts and construction, payroll changes from month to month: overtime, bonuses, sickness absences, cross-border employees living in France, Belgium or Germany. The construction sector also has its own compensation scheme for hours lost to bad weather, handled with ADEM. Each variable changes the contribution base and the wage-tax withholding.
We collect these items by site or by team, and reconcile payroll costs with the margin of each site in accounting for construction firms.
Why outsource payroll?
Running payroll in-house means software, constant monitoring of labour law, the index and rate schedules, and availability every month. For an SME, the error risk and hidden cost are high. Outsourcing transfers that risk to a licensed accountant and frees your teams.
You gain reliability (compliant payslips and filings), continuity (no dependence on a key person) and clarity (one cost per employee, no surprises).
How much do payroll services cost?
Indicatively, outsourced payroll starts at EUR 20 excl. VAT per payslip, with a one-off set-up for affiliation and parameters. Cost depends on the number of payslips, benefits in kind, cross-border workers and complexity (variable hours, bonuses, plans).
