Your real obligations, the 50,000 € VAT exemption, when an accountant becomes worth it and what it costs, whether you work in your own name or through a company.

In short. A self-employed person or freelancer in Luxembourg must keep accounts, handle VAT and declare income, whether the activity runs in their own name or inside a company. Below 50,000 € of annual turnover, the VAT exemption makes life simpler but does not remove the duty to keep books. An accountant becomes genuinely useful as soon as the activity takes shape: a company, VAT to pay, employees, or simply the wish to stop losing your evenings to spreadsheets. At Advena, support starts from 325 € per month, all in, and we tell you plainly when you do not need it yet.

"Do I really need an accountant?" is the first question a self-employed person asks when starting out in Luxembourg, and the honest answer is: it depends where you stand. Here are your real obligations by situation, the role of the VAT exemption, the point where delegating pays off, and what the service costs, without a vague range.

Own name or company: two accounting regimes

Before talking about an accountant, you need to know which status you operate under, because the obligations differ in scale. In your own name, you are an individual carrying out a commercial, craft or professional activity. Your profit is taxed under income tax, on the progressive scale, and depending on your activity and size you fall under lighter or heavier accounting duties, as the Guichet.lu portal sets out.

In a company (most often a Sàrl or a Sàrl-S), you create a separate legal person. There, the obligations are full: double-entry bookkeeping under the standard chart of accounts, annual accounts filed with the trade register, taxes on the company's result. It is heavier, but it protects your personal assets and opens other options. The choice between the two depends on your activity, your income and your plans, and it deserves to be settled early, before the accounting piles up.

The 50,000 € VAT exemption: what it changes

This is the point that touches the most people starting out. Since 1 January 2025, the small business exemption scheme applies up to 50,000 € of annual turnover, with a 10% tolerance (up to 55,000 €), according to the indirect taxation portal. Below that threshold, you do not charge VAT and you do not declare it, provided your invoices carry the wording "VAT not applicable, article 57bis of the amended law of 12 February 1979".

Two traps to know. First, the exemption does not free you from keeping accounts: you still have to track your income and expenses, if only to prove you stay under the threshold. Second, it has a hidden cost: with no VAT charged, you do not reclaim the VAT on your purchases. For an activity that invests (equipment, subcontracting), opting out of the exemption is sometimes the better deal. This is exactly the kind of trade-off where an accountant's view earns more than it costs. The full workings of Luxembourg VAT are covered in our article on VAT returns in Luxembourg.

Your other obligations, beyond VAT

Being self-employed in Luxembourg is not only about VAT. Three other appointments pace the year, whatever your status.

  • Social affiliation. Every self-employed person registers with the Joint Social Security Centre and contributes on their professional income. These contributions are not optional and should be set aside, or the bill comes as a shock.
  • The income declaration. In your own name, your profit is added to your other income in your income tax return. In a company, the company declares and pays its own taxes, the calculation of which we detail in our article on corporate tax.
  • The business permit. Many self-employed activities need this green light before the first invoice, as we explain in our guide to the business permit.

None of these is beyond you on your own. The real cost is the time they take and the blind spot they create: when you do your books on a Sunday evening, you do them late and without perspective.

Starting out as self-employed and unsure what is mandatory in your case? Let's take stock together, no strings attached.

Take stock of my situation

When an accountant becomes genuinely useful

Let's be honest, which is rare in our trade: not every self-employed person needs an accountant right away. If you work in your own name, below the exemption threshold, with a handful of invoices a year and no significant purchases, a well-kept spreadsheet and some discipline often do for the first year. Paying a monthly fee for that would make no sense, and we will say so.

Delegating pays off as soon as one of these lines is crossed: you move to a company, you exceed the exemption and must declare VAT, you hire, your invoice volume takes off, or you start making decisions (investing, recruiting) that need reliable, current figures. At that stage, the time you spend on accounting is worth more than the fee, and a VAT error or a late filing costs more than support. The question is no longer "can I do it myself" but "is this the best use of my time".

What does an accountant cost for a self-employed person in Luxembourg?

The market is opaque: most firms bill by the hour, between 70 € and 300 € excluding VAT, without publishing prices, which we detail in our article on what an accounting firm costs in Luxembourg. For a self-employed person, this model is particularly punishing: every call, every question becomes a line on the bill, and the annual budget is impossible to anticipate.

At Advena, support starts from 325 € per month, all in: current bookkeeping, VAT and eCDF filing, annual accounts and register filing for companies, payroll if you have staff, a monthly review with a dedicated manager and permanent real-time access to your accounts. No bill lands outside the monthly fee. For a self-employed person who has structured their activity, it is a budget known in advance rather than a meter that keeps running.

The cross-border self-employed case

Many people who work as self-employed in Luxembourg live in Belgium, France or Germany. The principle is simple: what matters in order to operate is the genuine establishment of the activity in the Grand Duchy and compliance with local conditions, not your place of residence. However, the personal tax of a cross-border self-employed person straddles two countries and deserves a case-by-case look. We inform here on the Luxembourg framework; for your personal cross-border situation, a dedicated review is in order, and we point you the right way rather than generalise wrongly.

The Advena difference for a self-employed person

We keep your books inside the Odoo we configure for Luxembourg, not in a corner you never see. In practice, your bank feeds and your invoices arrive in the system and file themselves, and you check your position whenever you want, not eight months later. For a self-employed person, this real time is a game changer: you know where you stand before committing to a purchase or a hire. It is the coupling between the management tool and the bookkeeping that our guide to accounting firms in Luxembourg describes, and that no traditional firm offers.

Frequently asked questions

Does a self-employed person have to have an accountant in Luxembourg?

No, the law does not require using an accountant. It does require keeping accounts, handling VAT and declaring income. Many self-employed people delegate as soon as the activity takes shape, because the time saved outweighs the cost.

What turnover qualifies for VAT exemption?

Since 2025, the exemption applies up to 50,000 € of annual turnover, with a 10% tolerance. Below that, you do not charge VAT, but you do not reclaim it on your purchases either, and you must still keep your books.

Is it better to work in your own name or through a company?

Own name is simpler and lighter, but your personal assets are on the line and the profit is taxed in your name. A company protects your assets and opens other options, at the price of full accounting obligations. The right choice depends on your income, your activity and your plans.

What does an accountant cost for a freelancer?

The market often bills by the hour, between 70 and 300 euros, with no published price. At Advena, support starts from 325 euros per month, all in, with no hourly billing and no surprise extras.

Can a cross-border worker be self-employed in Luxembourg?

Yes. What matters in order to operate is the genuine establishment of the activity in Luxembourg and compliance with local conditions, not the place of residence. Personal cross-border tax, however, is looked at case by case.
