Freelancer Tax in Luxembourg: Everything Self-Employed Workers Need to Know

Freelancing in Luxembourg offers flexibility and often higher day rates — but it also means navigating income tax, VAT, social security contributions, and quarterly tax prepayments largely on your own. This guide covers the essentials for independent professionals working in or from Luxembourg.

Income Tax as a Self-Employed Person

Self-employed income in Luxembourg is taxed as business profit (bénéfice commercial) rather than employment income. The same progressive rate scale applies — from 0% up to 40% — but with some key differences:

• You can deduct genuine business expenses before tax (home office, equipment, professional subscriptions, travel)
• Social contributions are paid separately and are not automatically deducted at source
• You file a full income tax return (déclaration fiscale) annually with the ACD

Social Security for the Self-Employed

As a freelancer or sole trader, you register with the Centre Commun de la Sécurité Sociale (CCSS) as a self-employed person. Contributions cover health insurance, pension, and dependency insurance.

The rates are broadly similar to employee rates, but calculated on net business profit rather than gross salary. Many freelancers are surprised to find that social contributions can represent 25–35% of their net income.

VAT Registration

If your annual turnover exceeds €35,000, you must register for VAT in Luxembourg. Below this, the VAT exemption (franchise régime) simplifies administration.

Once VAT-registered, you must add VAT to your invoices, file quarterly VAT returns, and remit collected VAT to the AED. The standard rate is 17%, though knowledge-work services to EU business clients (B2B) follow the reverse charge mechanism with 0% Luxembourg VAT.

Quarterly Tax Prepayments

Unlike employees who have tax deducted monthly via payroll, self-employed individuals must make quarterly advance tax payments (bulletins de précompte). The ACD estimates your tax liability based on your previous year's income and bills you in March, June, September, and December.

If you had a significantly different income year (higher or lower than expected), you can request an adjustment.

Legal Structure: Sole Trader vs S.à r.l.

For most freelancers earning under €150,000/year, a sole trader structure is simpler. Above that, the S.à r.l. often becomes tax-efficient due to the lower corporate tax rate.
