Payroll & HR administration

Managing payroll in Luxembourg requires mastering a precise and constantly evolving social security framework. At Ease Advisory, we handle payroll calculation and all of the formalities relating to your employees, for reliable, confidential and compliant management, month after month.

Payroll calculation and management

Each month we prepare your employees' payslips, taking into account every parameter of the calculation:

• Tax scales and withholding tax cards
• Employer and employee social security contributions
• Benefits in kind and variable items
• Overtime, absences and leave

You receive clear documents, ready to be handed to your employees.

Social security formalities

We handle the filings and the relations with the competent bodies:

• Registrations and deregistrations with the Joint Social Security Centre (CCSS)
• Entry and exit declarations for your employees
• Transmission of the required data to the administration

We ensure that filing deadlines are met throughout the year.

2026 social parameters: rates, index and ceiling

The calculation of a Luxembourg payslip relies on parameters that move several times a year:

• Index: since 1 June 2026, the index figure applied to salaries stands at 992.24.
• Social minimum wage: EUR 2,771.33 per month for an unskilled employee, increased by 20% for a skilled employee and reduced by 20 to 25% for an adolescent worker.
• Contribution ceiling: five times the social minimum wage, i.e. EUR 13,856.63 per month.
• Adjustment: the CCSS recalculates this ceiling every month on a cumulative annual basis, so contributions are charged as soon as the ceiling is first exceeded.

Three rates deserve particular attention this year:

• Pension: the rate rose from 16% to 17% in 2026. This additional point, shared between employee and employer, affects both the employee's net pay and the employer's cost.
• Accident: 0.65%, a single rate adjusted for each company by a bonus-malus factor communicated by the Accident Insurance Association.
• Employers' Mutual Insurance Scheme: every new member contributes in class 2, the class being reassessed each year according to the company's financial absenteeism rate.

CCSS registration and declarations: the deadlines to meet

Before hiring its first employee, the employer files an operating declaration with the Joint Social Security Centre to obtain its employer registration number. Where the activity falls under the right of establishment, the business permit must have been applied for beforehand.

Registration triggers three mandatory affiliations:

• The Accident Insurance Association
• The Employers' Mutual Insurance Scheme
• An occupational health service

The company is automatically registered with the Multisector Occupational Health Service, unless a membership certificate from another service is submitted within three months of registration. The employer registration number then remains valid for the entire life of the company, unless the legal form changes.

Staff movements must be declared within eight days:

• Entry declaration: within eight days of the hiring.
• Exit declaration: within eight days of the end of the contract, the exit date being the last day of the employment relationship or the last day of the statutory notice period.
• Exception: no exit declaration is required as long as an absence for illness or maternity is being compensated by a health insurance fund.
• Channels: SECUline, MyGuichet.lu or paper form.

Each month, the employer also declares the gross remuneration paid and the exact number of hours paid for the previous month, and not a flat 173 hours. A late declaration exposes the employer to an administrative fine.

The detail matters as much as the deadline:

• Overtime must be declared separately, at 100% and without the 40% premium.
• Bonuses, profit shares and benefits in kind are not subject to contributions for cash sickness benefit or for the Mutual Insurance Scheme, but they are for pension and accident insurance.
• Meal vouchers, by contrast, are neither subject to contributions nor to be declared.

It is these distinctions that separate an accurate payroll from a reassessment.

Contracts and personnel administration

We take charge of the administrative side of your staff management:

• Drafting employment contracts and formalising amendments
• Administrative follow-up of your employees
• Information on the obligations relating to hiring, working time and termination of contract

All in compliance with the Luxembourg Labour Code.

Payment management

On request, we prepare the transfer orders for salaries and contributions, in order to offer you end-to-end management and to fully relieve you of the administrative side of payroll.

Wage tax withholding: frequency and tax cards

The employee's income tax is withheld at source by the employer, who is responsible for paying it over to the Direct Tax Administration. The frequency of declaration and payment depends on the total withheld over the month.

The return is filed via MyGuichet.lu and the payment is made to the competent collection office, quoting three items:

• The company's tax number
• The period concerned
• The reference of the return

The absence of withholding for a period does not remove the filing obligation: the return must then state that no tax was withheld. An employer that no longer pays remuneration subject to withholding may ask to be released from this periodic obligation by its RTS office.

Since 1 May 2021, withholding tax cards have been multi-annual and electronic:

• The administration makes them available to employers on MyGuichet.lu, in PDF or XML, and this access is mandatory.
• The employee no longer has to hand his card to his employer, but must still make sure that a card exists for his job.
• In the absence of a valid card, the employer applies the most expensive scale: class 1, with a rate that cannot be lower than 33%.
• Outside fixed-term contracts, the card remains valid until one of its elements changes.

Paying contributions and closing the year

The CCSS sends a statement of account each month, with a two-month lag between the month invoiced and the month of issue: March contributions appear on the May statement.

• The balance is payable within ten days of the issue of the statement, including in the event of a dispute.
• Contributions unpaid at the due date bear late-payment interest of 0.6% per full calendar month.
• The CCSS starts enforced recovery proceedings after four unpaid monthly statements.

Direct debit removes this risk, as do two basic habits: quoting the contributor account number, i.e. the registration number followed by extension 99, and making a separate transfer for each contributor account.

On the tax side, the year closes with the salary account statements, to be filed electronically with the Direct Tax Administration before 1 March of the year following the tax year:

• Filing on MyGuichet.lu, by XML file of 7 MB maximum or via an input wizard.
• A unique reference per tax year and per payer.
• A change of country of residence during the year requires two separate statements.
• A late or missing filing exposes the employer to additional tax or to a penalty payment.

This filing can be carried out by an appointed accounting firm: this is what we handle for our clients, together with the CCSS declarations and the monthly withholding tax returns.
