Payroll and statutory filings for Luxembourg
Upload contracts and tax cards. LuxPay computes every payslip at the rates in force, prepares the CCSS and ACD declarations and the accounting entry, and a QCS Luxembourg accountant reviews each month before it is approved.

Why now
In 2026 alone the employee pension contribution rose by half a point and wages were indexed in June. Each change reaches every payslip, every declaration and every year-end certificate. LuxPay keeps each rate with its official source and the date it takes effect, so a month is always computed with the rules of that month.

How it works
Upload contracts, tax cards and, when you switch provider, the last payslips. The AI reads them, scans included; you check the highlighted fields and confirm.
Hours, leave, sickness, bonuses, benefits in kind. A new tax card is tied to its own date, so earlier months stay as they were.
Every payslip at the rates of the month: contributions, withholding tax, CIS, CI-CO2 and CI-SSM credits and the indexation, to the cent.
A QCS accountant checks the month, the client approves it, and every change is kept in the audit trail.
DECSAL for the CCSS, Model 950 and the yearly ECSP for the ACD, the accounting entry and the salary summary. Employees find their payslips in their own space.
Features
Before a client goes live, LuxPay is reconciled line by line against the payslips of the previous provider, and every difference is explained.
Class, fixed rate and deductions follow the date on the card: a marriage in May changes May, not January.
Year-to-date figures and leave balances are read from the last payslips and carried over, so credits and leave continue where they were.
DECSAL, Model 950, ECSP and the entry and exit declarations, generated from the approved months and checked against the official formats.
The salary summary and the accounting entry for each month, and the yearly certificate of remuneration for every employee, in PDF.
The dashboard lists every declaration due, per company, and shows what is late.
Entitlement from the contract, balances carried over and leave taken, for every employee.
The calculator answers "which gross gives 3,000 net?" with the class, the fixed rate and the deductions of a real tax card.
Ask a question from any screen; a QCS accountant answers in the same window.
