Luxembourg company formation guide

Open a company in Luxembourg

A complete practical guide for entrepreneurs, foreign founders, investors and small businesses who want to open a company in Luxembourg and understand every step before speaking with a notary, accountant or business adviser.

Company formation

What does it mean to open a company in Luxembourg?

To open a company in Luxembourg, you normally need to choose the right legal form, secure a Luxembourg registered office, prepare the incorporation documents, meet business permit requirements where applicable, deposit the share capital when required, register the company with the Luxembourg Trade and Companies Register and organise tax, VAT, accounting and social security obligations.

The exact process depends on your activity, your nationality or residence situation, the shareholders, the managers, the sector and the level of substance you want to build in Luxembourg. This page answers the main questions around opening a Luxembourg company in one place.

Who can open a company in Luxembourg?

Luxembourg company formation is open to local and foreign founders. A non-resident can be a shareholder, and international groups can create a subsidiary or branch. The key practical question is not only ownership, but management, business permit eligibility, local address, banking, tax substance and the activity carried out from Luxembourg.

If you are outside the EU/EEA, check immigration, residence and work-authorisation consequences before assuming that owning a Luxembourg company gives you the right to live or work in Luxembourg.

Main legal forms for a Luxembourg company

The most common options are the SARL for small and medium-sized companies, the simplified SARL-S for eligible natural-person entrepreneurs, the SA for larger or more formal shareholding structures, a branch for an existing foreign company, or a sole proprietorship for self-employed activities.

For many founders, the choice is between SARL and SARL-S. SARL usually offers credibility and flexibility, while SARL-S can reduce the initial capital barrier but has restrictions. Regulated, investment, financial, holding or international structures should be reviewed with a professional adviser.

Business permit and regulated activities

Many commercial, craft, industrial and certain liberal-profession activities require a business permit before starting operations. The authorities may look at professional integrity, qualifications, effective management and a fixed establishment in Luxembourg.

Do not treat incorporation as the end of the process. A company can exist legally while still needing authorisations before it can invoice, hire, operate premises or provide regulated services.

Registered office and real presence

A Luxembourg company needs a registered office. For SEO searches such as “open a company in Luxembourg”, this is often misunderstood as a simple mailbox. In practice, banks, tax advisers and authorities may ask what activity is really managed in Luxembourg, who makes decisions, where documents are stored and whether the company has sufficient substance for its business model.

The right setup may be a business centre, a serviced office, a dedicated office, a domiciliation arrangement with a professional provider or operational premises, depending on the activity.

Bank account and share capital

Some legal forms require subscribed and paid-in share capital. Banks and payment institutions will normally request identification documents, beneficial-owner information, proof of address, activity description, source of funds and sometimes contracts or business plans.

Opening the account can be one of the slowest parts of the project, especially for non-residents, high-risk sectors or complex ownership structures. Start this step early.

RCS, RBE, tax, VAT and accounting

After incorporation, the company generally needs registration with the Trade and Companies Register, beneficial-owner declarations where applicable, tax registration, accounting setup and VAT analysis. VAT registration depends on the activity, taxable supplies and cross-border flows.

If the company hires staff, pays directors or has self-employed managers, social security and payroll topics must also be checked. Luxembourg bookkeeping, annual accounts and filings should be planned from day one.

Timeline to open a company in Luxembourg

A simple project can move quickly once the documents, bank and authorisations are ready. In practice, timing depends on legal form, notary availability, bank onboarding, business permit processing, regulated activity checks, non-resident KYC and the quality of your file.

The fastest projects are usually those with a clear activity, simple ownership, prepared identification documents, clean source-of-funds explanations and a realistic registered-office solution.

Cost of opening a Luxembourg company

Costs vary by legal form, notary involvement, translation needs, business permit, adviser fees, registered office, accounting, bank, VAT and sector regulation. The cheapest setup is not always the safest: underestimating accounting, tax, substance or authorisation requirements can cost more later.

Before you open a company in Luxembourg, build a budget for incorporation and for the first year of operation, not only the day-one company formation cost.

Common mistakes to avoid

Frequent mistakes include choosing a legal form only because it is cheap, ignoring the business permit, using a weak registered-office setup, delaying bank onboarding, forgetting beneficial-owner declarations, assuming VAT is automatic, not checking employment and payroll consequences, and treating Luxembourg as a “paper company” jurisdiction.

A better approach is to prepare the commercial project, legal structure, management, substance, banking and compliance package together.

Checklist before you start

Define the exact activity, countries served, founders, managers, shareholders, beneficial owners, capital, registered office, licences, expected turnover, hiring plan, accounting provider, bank strategy and first contracts.

With those elements prepared, a notary, accountant or Luxembourg business adviser can give a much more precise answer on how to open the company, how long it will take and what the realistic cost will be.
