Luxembourg SARL Company Formation: Costs, Taxes & Steps (2026)

Want an LLC in Luxembourg that banks, partners and investors take seriously? A Luxembourg SARL — the société à responsabilité limitée — is the country's limited liability company. Your liability is limited to what you put in. One owner is enough. You don't need to live there. Since June 2026, you can even form it first and pay the EUR 12,000 capital within 12 months. Add a AAA rating and EU market access, and it's no surprise this is Luxembourg's most popular type of company. Here's how it works, what it costs and how to start.

What Is a Luxembourg LLC (SARL)?

Here's the short version: the SARL is Luxembourg's answer to the LLC.

Its full name is Société à Responsabilité Limitée. Like a limited company anywhere, it's a separate legal person. It blends two things:

• Corporation-style protection. Owners risk only their capital contributions. That's the liability protection most people are after.
• Partnership-style control. Shares are not freely sold to outsiders, so you decide who joins.

It's not a niche structure. Guichet.lu, the government's business portal, says about two-thirds of Luxembourg companies are SARLs. And the Luxembourg Business Registers counted more than 78,000 SARLs on the register (data at 30 March 2026).

Luxembourg SARL vs a US LLC

If you know the US LLC, the SARL will feel familiar. Both offer limited liability and simple management. But they differ in key ways:

• Tax. US LLCs are often taxed as pass-through entities. A SARL is a taxpayer in its own right — its profits are taxed at company level.
• Capital. A US LLC has no minimum capital. A SARL needs EUR 12,000 (or from EUR 1 for the simplified SARL-S).
• Formation. A US LLC is filed with a state and gets an EIN from the IRS for tax. A SARL is formed by a notarial deed and gets a Luxembourg tax number instead.
• Agent. US states require a registered agent. Luxembourg does not — but it does require a registered office in the country.

Why Choose a Luxembourg SARL?

Why pick this country over a zero-tax island? Because credibility opens doors that low tax can't.

• Limited liability. You risk only the capital you put in — not your house or savings. Good asset protection starts here.
• One owner is enough. A single-member SARL is allowed, and the single partner makes every decision.
• Any nationality. Your nationality doesn't matter. Shareholders and managers can live anywhere. No local manager is required.
• Discretion, not secrecy. Shares are never publicly listed or offered. Be aware: a SARL's shareholders are listed on the public Trade and Companies Register, and annual accounts are filed there too. The beneficial owner register (RBE) is different — public access was suspended after a November 2022 EU court ruling, and it is now open only to authorities, regulated professionals and people with a legitimate interest.
• Prime EU location. The Grand Duchy borders France, Germany and Belgium, and belongs to the EU and OECD.
• A trusted name. AAA rating, a huge fund industry and strong banks. This is not a brass-plate jurisdiction.
• Flexible setup. A simple business structure with fewer formalities than a public company, and the Articles can be tailored to you.

SARL vs SA vs SARL-S: Which Type of Company Fits You?

The country offers several legal structures. Choosing the right type of company comes down to size, capital and who owns it.

1. SARL (private limited liability company). A minimum of one and a maximum of 100 shareholders. EUR 12,000 capital. Registered shares only. Best for holding companies, family businesses and subsidiaries.
2. SA (société anonyme). A public limited company. For larger ventures. EUR 30,000 minimum capital, a board, and shares that can be traded. It can raise money from the public — a SARL cannot.
3. SARL-S (simplified SARL). Capital from EUR 1 up to EUR 12,000, and it can be formed by private deed, without a notary. But Guichet.lu's SARL-S rules are strict: only natural persons can own it, each person can hold just one SARL-S, managers must be individuals, and it's reserved for craft, trading, manufacturing and certain professional activities with a business permit. So it's not an option for corporate owners, legal entities or pure holding structures.

What Can You Use a Luxembourg SARL For?

What do owners actually build with one? Mostly things that need a solid European base.

• EU holding companies — the classic use
• Family wealth and ownership structures
• Wholly owned subsidiaries of foreign groups
• Joint ventures where partners want control over who can buy in
• Vehicles holding venture capital and private equity stakes
• Intellectual property and real estate holding
• Trading businesses that want EU credibility

One limit: insurance, savings and investment companies can't be set up as SARLs.

Key Corporate Features of a Luxembourg SARL

How Much Does a Luxembourg LLC Cost?

Is it expensive? It's premium — but the government's own fees are small.

• Our complete SARL formation service: US$6,500. This covers the notarial deed, registered office in Luxembourg, RCS filing and guidance on banking and compliance.
• Annual renewal: from US$4,100. Covers registered office, filings and administration.
• Government costs. A fixed EUR 75 registration duty on the deed, plus an RCS registration fee of EUR 105.91 plus VAT.
• Share capital: EUR 12,000. This isn't a fee. It's your own money, paid into your company.

How Do You Register a Luxembourg SARL? Step by Step

Good news: the incorporation itself can be done in a day or two once your papers are ready. Here's the full path.

1. Pick your name. Choose a company name and check it's free with the Trade and Companies Register (Registre de commerce et des sociétés, RCS). It must differ from every existing company, and your official documents must show the words "société à responsabilité limitée".
2. Check licences. If the company will trade or offer services, you'll usually need a business permit from the Ministry of the Economy.
3. Prepare KYC. Passports, proof of address, source of funds and a short business rationale. The anti-money laundering checks are strict, so clean files save weeks.
4. Draft the Articles. Your Articles of Association state the name, registered office, purpose, share capital, shareholders, duration and management. If you defer capital, the Articles must also set the payment terms.
5. Sign the deed. This is a notarial act. A local notary executes the deed. You don't need physical presence — a power of attorney works.
6. Register and publish. The deed is filed with the RCS and published in the RESA, the official electronic gazette.
7. Declare beneficial owners. Owners are recorded in the beneficial owner register (RBE).
8. Register for tax and, if needed, VAT.
9. Open the bank account and pay in the capital — now possible up to 12 months after the time of incorporation.

The notary signing can happen within 1–2 days of a complete file; allow 2–3 weeks end to end. Want the longer version? Read our guide on how to set up a company in Luxembourg.

Do You Need a Physical Office?

It depends on what the company does. A holding company can use a domiciliation agreement — but only with a regulated professional. Under the Law of 31 May 1999, domiciliation agents must be banks or other financial-sector professionals, lawyers, auditors or chartered accountants. A generic "virtual office" address won't do. Trading businesses that need a business permit generally need a real establishment in Luxembourg. And if you want Luxembourg tax residence and treaty benefits, plan for real substance, such as local management.

Opening the Bank Account (and Clearing KYC)

Here's the truth most formation sites skip: the bank is the hardest part.

• Banks want a clear reason for your choice and real ties to the country.
• KYC and AML reviews cause most delays. Airtight owner and manager files from day one are critical.
• Some banks are stricter than others. An existing relationship helps.
• Electronic payment institutions can be a faster stopgap.
• Since 2 June 2026, the bank no longer blocks your incorporation. The account can open in parallel.

This is where our professional service earns its fee. We build your KYC file right the first time and match you to banks that fit your profile.

How Are Luxembourg SARLs Taxed?

This isn't a zero-tax haven. It trades a little tax for a lot of trust. Here's the taxation picture since tax year 2025:

• Corporate income tax: 14% on taxable income up to EUR 175,000 and 16% above EUR 200,000. In between, a formula applies (EUR 24,500 plus 30% of income above EUR 175,000).
• Solidarity surtax: 7% of the CIT amount (it funds the employment fund).
• Municipal business tax: set by each commune. It's 6.75% in Luxembourg City. All in, the top corporate tax rate there is about 23.87%.
• Where income is taxed: resident companies pay on worldwide income. Non-resident companies pay only on Luxembourg income.
• Dividends: 15% withholding tax, with exemptions — for example under the parent-subsidiary regime — and lower rates under tax treaties. Ordinary interest and royalties carry no withholding tax.
• Net wealth tax: 0.5% on net wealth up to EUR 500 million. Most small companies pay a minimum instead: EUR 535, 1,605 or 4,815 a year depending on balance sheet size, reduced by any corporate income tax paid.
• VAT: 17% standard rate, if you register.

A wide treaty network also helps you avoid double taxation and gives holding structures real tax flexibility. Very large groups (EUR 750 million+ revenue) fall under the 15% global minimum tax.

What Are the Ongoing Reporting Requirements?

Forming the company is day one. What do you owe every year after that?

• Annual accounts. File with the RCS within 7 months of your financial year end (6 months to approve them, plus 1 month to file). Late filing costs extra: EUR 50 in the 8th month, EUR 200 in months 9–11 and EUR 500 after that.
• Tax returns. Corporate income tax, municipal business tax and net wealth tax returns go to the ACD by 31 December of the year after the tax year. The company also pays quarterly tax advances.
• Beneficial owner updates. Keep the RBE current when owners change.
• Audit. A statutory audit applies only if you pass two of three limits for two years in a row: EUR 7.5 million balance sheet, EUR 15 million turnover, or 50 employees. These were raised from EUR 4.4M / EUR 8.8M by the Grand-Ducal Regulation of 25 October 2024. SARLs with more than 60 shareholders also need an internal auditor (supervisory board).
• Meetings. An annual general meeting is only mandatory for SARLs with more than 60 shareholders. Smaller SARLs can vote in writing.

These reporting obligations are light for a small SARL, but miss them and the penalties add up.

Shares, Managers and Control

Who really controls a SARL? You do — and the rules are built to keep it that way.

• Registered shares only, with or without nominal value. Public share offers are banned.
• Transfer of shares to outsiders needs approval from shareholders holding at least 75% of the share capital. The Articles can lower this, but not below 50%. Transfers between existing shareholders are free unless the Articles say otherwise.
• Profit shares can be issued outside the capital, with rights set in the Articles.
• Managers can be individuals or companies, of any nationality. Shareholders can manage the company themselves. In practice, law firms and fiduciaries often provide local managers for substance.
• Duration can be unlimited. A shareholder's death or bankruptcy does not end the company.

This all runs under Luxembourg law, a civil law system with strong shareholder protections.

How Is Luxembourg Company Formation Changing in 2026?

Did you know you can now form a SARL without a bank account in place?

The development: the Law of 18 May 2026 amended the 1915 company law and took effect on 2 June 2026. Parliament's aim, set out when Bill 8669 was debated, was to stop bank account delays holding up new companies. Founders can now defer paying the EUR 12,000 minimum capital for up to 12 months, or a shorter period if the Articles say so. The capital must still be fully subscribed at incorporation, and only cash contributions can be deferred. Capital above EUR 12,000, share premium and contributions in kind must be paid up front. It applies to SARLs and SARL-S formed from 2 June 2026, not existing ones — and founders stay liable for any unpaid amount.

The stat: the reform hits the most-used vehicle in the country. Luxembourg Business Registers data show more than 78,000 SARLs registered as at 30 March 2026.

Our insight from forming companies since 1996: the old rule put the slowest step — bank KYC — in front of the notary. We've watched deals wait weeks on a compliance queue while the paperwork sat ready. Now the company exists first and the bank catches up. Notice what didn't change: the capital amount and the AML checks. The country didn't get cheaper or looser. It got faster.

Our hedged prediction: in a 12 March 2026 parliamentary answer, the government said it plans a further one-point cut to the corporate income tax rate from tax year 2027 (Paperjam). If that passes, small SARLs could see a slightly lower bill again. But budgets change, so treat it as likely, not certain — and expect more procedural streamlining rather than big giveaways.

How Does Luxembourg Compare?

Is it right for you? It depends on what you value most.

This jurisdiction buys you prestige, banking depth and EU access at a moderate tax cost. It shines for holding companies and wealth structures. If your top priority is the lowest EU tax rate for a trading business, compare it with a Hungarian Kft at 9% corporate tax.

Frequently Asked Questions

• Can a foreigner start a business in Luxembourg?

  Yes. A single foreign shareholder can form and fully control a Luxembourg SARL. Shareholders and managers can be any nationality, no local manager is required, and you can sign through a power of attorney without travelling.

• How much does it cost to form and renew a Luxembourg company?

  Our complete SARL formation service is US$6,500, covering the notarial deed, registered office and RCS filing. Annual renewal starts from US$4,100. Government costs are small: a fixed EUR 75 registration duty plus an RCS fee of EUR 105.91 plus VAT. The EUR 12,000 minimum share capital is your own money paid into the company, not a fee.

• Do I have to pay the EUR 12,000 capital before incorporating?

  Not anymore. Since 2 June 2026, the EUR 12,000 must be fully subscribed at incorporation, but cash payment can be deferred for up to 12 months. Capital above EUR 12,000, share premium and contributions in kind must still be paid in full at incorporation, and founders stay liable for any unpaid amount.

• How long does it take to register an LLC in Luxembourg?

  The notarial deed can be signed within 1–2 days once documents are ready. Allow 2–3 weeks end to end. Bank account opening is usually the slowest step, but since June 2026 it no longer has to be finished before the company is formed.

• Do I need to travel to Luxembourg or have a physical office?

  No travel is needed — a power of attorney can cover the notary signing. You need a registered office in Luxembourg. A holding company can use a domiciliation agreement with a regulated professional such as a bank, lawyer, auditor or chartered accountant. Trading businesses generally need a real establishment, and local substance helps if you want Luxembourg tax residence.

• What is the difference between a Luxembourg SARL and an SA?

  A SARL is private: 1 to 100 shareholders, EUR 12,000 minimum capital, registered shares only and no public share offers. An SA is a public limited company with EUR 30,000 minimum capital and shares that can be traded and offered to the public.

• What is a SARL-S?

  A simplified SARL with capital between EUR 1 and EUR 12,000, formed by private deed without a notary. Only natural persons can own it, each person can hold only one, managers must be individuals, and it's reserved for craft, trading, manufacturing and certain professional activities with a business permit.

• What tax will my Luxembourg SARL pay?

  Corporate income tax is 14% on income up to EUR 175,000 and 16% above EUR 200,000, plus a 7% solidarity surtax and municipal business tax (6.75% in Luxembourg City). The top all-in rate in Luxembourg City is about 23.87%. Dividends carry 15% withholding tax unless an exemption or treaty rate applies. Net wealth tax (or the minimum charge) and VAT may also apply.

• What are the annual reporting obligations for a Luxembourg SARL?

  You must file annual accounts with the RCS within 7 months of year end, file corporate tax returns with the ACD by 31 December of the following year, and keep beneficial owner records current. A statutory audit applies only above the size thresholds.

• Is it hard to open a bank account for a Luxembourg SARL?

  It's the most demanding step. Banks expect clear reasons for using Luxembourg and complete KYC and AML files on owners and managers. Since June 2026, the account can be opened after incorporation because capital payment can be deferred.

• Are a Luxembourg SARL's owners kept private?

  Partly. A SARL's shareholders are listed on the public Trade and Companies Register, and its annual accounts are filed there. The beneficial owner register is no longer open to the general public — access is limited to authorities, regulated professionals and people with a legitimate interest.

• Can I use a Luxembourg SARL as a holding company?

  Yes. The SARL is the most common legal form for Luxembourg holding companies. It can own shares in subsidiaries anywhere, can use Luxembourg's parent-subsidiary rules on qualifying dividends, and can be domiciled with a regulated professional. The simplified SARL-S is not suitable for holding structures.
