Built for Luxembourg's payroll rules

Each feature, what it does, and what changes for you once it is on.

Payroll

Once your employees are in, payroll is a single run per month. Salary.lu computes gross to net for each person from their tax card, the current CCSS contribution ceilings and the wage index in force, then produces the payslips as PDFs. You can correct them at any time and recreate a payslip whenever necessary.

Key benefits

  • Tax classes, contribution ceilings and index tranches applied automatically
  • One run for all employees, hourly and salaried
  • Payslips corrected and recreated whenever necessary
  • Past payslips imported by our team when you switch, so the year-to-date figures are right
This run 14 payslips 61 420,00 € gross · 48 973,42 € net Payslips ready as PDFs

Leaves and absences

Each leave type is a choice in a list: legal leave, illness leave, illness leave paid by the CNS, maternity leave, accident leave, family leave and special leave such as adoption. Each absence lands on the right payslip line, and the remaining leave balance is shown on the payslip. With SECUline, the absences the CCSS has to know about are declared for you.

Key benefits

  • Statutory leave types, each with its own payslip treatment
  • Remaining leave balance shown on each payslip
  • Employees request time off in the portal, you approve or refuse it
  • Incapacity absences declared to the CCSS when SECUline is active

SECUline

SECUline is an option you add to your subscription. Once it is active, exchanges with the CCSS go through our SECUline connection, so you need none of your own. Entry and exit declarations and social security number requests are sent from Salary.lu, and the monthly salary declaration goes out automatically at the start of the following month. If the CCSS rejects a file, our team follows it up.

Key benefits

  • Entry and exit declarations sent from Salary.lu
  • Social security number requests for new employees, with the number filled in once the CCSS assigns it
  • Monthly salary declaration sent automatically
  • CCSS rejections followed up by our team

Key benefits

  • Salary and work certificates in a few clicks
  • U1 certificate and calculation of statutory vacations from the same data
