A payroll engine that handles CCSS declarations, income-tax classes, multi-CCT rules and legal electronic payslips in one place. Hosted in Luxembourg and never outside the EU, so your payroll data stays sovereign by design.
CCSS declarations · tax classes · multi-CCT · legal e-payslips
Payroll in Luxembourg is not just a calculation. Four moving parts have to line up every month — and generic payroll tools rarely cover them all.
Monthly declarations to the CCSS have to be produced and reconciled for every hire, departure and payroll run. A gap or a late filing is an administrative risk, not a rounding error.
Income-tax withholding depends on each employee's tax class (1, 1a, 2) and must be reconciled with the tax administration. Getting a class or a rate wrong shows up on the next payslip.
Sector collective agreements (CCT) set different rules per population — wage indexation (échelle mobile), seniority steps and sector-specific rules that a single flat payroll rarely models well.
Electronic payslips have to meet legal requirements and be kept for statutory retention periods. Loose PDFs in a shared drive are hard to prove and hard to keep in order over time.
Each obligation above maps to a capability that ships with the platform — not a module you buy later.
Hires, departures and monthly payroll produce the declarations expected by the CCSS, ready to be filed and reconciled — so the monthly close is a review, not a rebuild.
Tax classes (1, 1a, 2) drive income-tax withholding on every payslip, with outputs aligned to what the tax administration expects and kept consistent as situations change.
Collective-agreement rules — wage indexation, seniority and sector specifics — are applied per employee population, so different CCTs coexist without a separate payroll each.
Payslips are issued electronically and archived in an employee digital safe, kept for the statutory retention period and available to the employee and to HR when needed.
The reasons a regulated Luxembourg organisation picks Luxapps over a generic international suite.
Your HR data is hosted in Luxembourg and never leaves the EU. No transfer to a third country, no US cloud dependency — sovereignty by design.
Software tailored to your processes, with no per-user licence. Add your whole workforce without the bill scaling with headcount.
A transparent model: you pay for the software that exists — by the line of code, per month — with no upfront development fees.
You validate the delivery before it counts. If it does not fit, it does not ship — you are not billed for work you did not accept.
GDPR, access control and audit logging are part of the platform, backed by the DPO and CISO expertise of our partner Luxgap.
Legal, security and engineering under one roof. A single interlocutor for the software and the obligations around it.
Luxapps serves regulated sectors — banking and finance, health, and public administration — where a payroll data leak is a regulatory event. Our compliance posture is backed by Luxgap, the Luxembourg firm that operates our outsourced DPO and CISO mandates (GDPR, AI Act, NIS 2, DORA).

Yes. Hires, departures and monthly payroll produce the declarations expected by the CCSS, ready to be filed and reconciled each month, so the payroll close is a review rather than a rebuild.
Income-tax withholding is driven by each employee's tax class (1, 1a, 2), with outputs aligned to what the tax administration expects. When a situation changes, the class is updated and applied on the next payslip.
Yes. Collective-agreement rules — wage indexation (échelle mobile), seniority steps and sector specifics — are applied per employee population, so several CCTs can coexist without running a separate payroll for each.
Payslips are issued electronically and archived in an employee digital safe, kept for the statutory retention period and available to the employee and to HR. We design to the applicable legal requirements; the exact modalities are confirmed for your setup during onboarding.
Yes. A fiduciaire can run payroll across multiple client companies from one platform, with access separated by client (by role and by ownership) and a full audit trail. The setup is tailored to how your firm organises client portfolios.
There is no per-user licence. You pay for the software that exists — by the line of code, per month — with no upfront development fees, and you validate each delivery before it is billed. Book a demo for a scoped estimate.
