Net salary principle

In Luxembourg, your employer deducts income tax directly from your salary. 

This means that at the end of the month, you will receive a net salary, after deduction of social security contributions and your estimated income tax.

Taxation and payment of income tax at source

Income tax in Luxembourg is deducted directly at source on the basis of a tax form issued annually by the tax authorities. This tax form determines your tax class according to your family situation and status.

Employees and pensioners pay their income tax directly at source. This means that your employer pays you a net salary each month , less the amount of income tax due.

Your employer calculates your income tax on the basis of a tax deduction slip, issued individually by the Luxembourg tax authorities. It then deducts the tax from your salary or pension.

Please note that even if salaries are taxed at source, you must still declare all your income to the tax authorities once a year. See below.

Principle of the Luxembourg withholding tax form

In Luxembourg, a tax card or "fiche de retenue d'impôt" is issued for each job or pension.

Updating the withholding tax form

The withholding tax form is systematically drawn up by the tax authorities, who send it to the taxpayer every year. In the event of a change in the taxpayer's situation, such as a change of job, retirement, marriage, birth of a child, etc., the taxpayer receives an updated withholding tax form.

All withholding tax forms are sent by post to the taxpayer's home address. On receipt, you must forward it to your employer for calculation of your withholding tax.

Didn't receive anything? Contact your local RTS office, depending on where you live.

Who needs a tax form?

Anyone engaged in a professional activity must have a withholding tax form. However, in principle, a withholding tax slip is not required in the following cases:

Your first job in Luxembourg? You will receive your tax card as follows:

  • If you are a resident and an employee who is a resident taxpayer, you will receive your tax card directly, without any action on your part. This is because the tax authorities issue the tax card after your new employer has affiliated you to the CCSS. You will receive your tax card within a maximum of 30 working days.
  • If you are an employee and a non-resident (frontier worker), you must request your tax withholding slip as soon as you start work. To do so, you must contact the non-resident RTS office in Luxembourg. In subsequent years, you will automatically receive a form to complete and send to us.

What should I do with my tax deduction slip or tax card?

As soon as you receive your tax card from the tax authorities, don't forget to pass it on to your employer. This tax deduction card enables your employer to identify the tax class to which you belong. This will enable them to calculate and deduct your tax directly at source.

In the absence of a withholding tax form, the employer arbitrarily applies the most onerous tax class and withholding tax rate. The rate will only be adjusted on receipt of the tax form. It is therefore important that your employer receives the tax card as soon as possible.
