Converting Between an EURL and a SARL

An EURL is a SARL with a single shareholder, and a SARL is an EURL with two or more. Because they are the same company form, moving between them is one of the smoothest transitions in French company life - no transformation, no new company, only an update of who the shareholders are. A second shareholder joining turns an EURL into a classic multi-member SARL; all the shares ending up in one hand turns a SARL back into an EURL. This guide explains both directions: the events that trigger each, the light formalities involved, the tax consequences that are the real substance of the change, and the drafting choices that decide whether the shift works for you or catches you out.

The reason this matters in practice is that the triggering events are usually driven by life or business, not by a decision to "convert": a partner is brought in to fund growth, a co-shareholder is bought out, a marriage ends, an owner dies. The company slides from one state to the other as a by-product. Understanding the move in advance means you can shape those moments - through the articles you drafted and the tax options you diarised - rather than react to them after the fact.

One company form, two states

The starting point is the single most useful fact about the EURL and the SARL: they are not two different company forms. The EURL is only the name given to a SARL that happens to have one shareholder. So the passage from one to the other is not a transformation in the legal sense - concentrating all the shares in one hand does not bring about a legal transformation of the company, and neither does the arrival of a new shareholder. The company keeps its legal personality, its registration number, its history and its contracts throughout.

That is why the formalities are so light. Going in either direction, the only steps are those inherent in the underlying event - a share transfer, a capital increase, a capital reduction - which generally translate into a matching update of the articles filed at the trade and companies register. There is no dissolution, no re-incorporation, no fresh capital deposit. What changes hands is not the company's form but its membership and, as we will see, often its tax regime.

Because the move is so easy structurally, the important work is done in advance, in the articles. A founder who drafts the statutes to cover both the one-member and the multi-member state - including an approval clause and the classic-SARL governance rules - will find the transition genuinely frictionless when it comes. A founder who drafts only for the state they are in today can find the shift forced on them, on terms they would not have chosen. The ease of the conversion is real, but it rewards foresight.

One practical caution follows from the "same company" principle. Because there is no transformation and no new entity, it must be clear on the record that the continuing company is the former one - the same registration, carried forward. Where the paperwork is thin, a counterparty has been able to argue that the SARL did not succeed to the rights of the former EURL because no transfer deed or updated articles could be produced. The lesson is administrative but important: keep the deed and the amended, filed articles, so the continuity that the law grants is also provable in fact.

From EURL to SARL: when a shareholder joins

An EURL becomes a classic multi-member SARL the moment a second shareholder appears, and that can happen several ways. The single shareholder may sell or give part of the shares to someone new; a capital increase may be subscribed by an incoming shareholder; a divorce may split community shares between the spouses; or the shareholder's death may bring several heirs in. A total sale of all the shares to a single buyer keeps the EURL one-member - though even then, the buyer's community-regime spouse may claim to become a shareholder and make it multi-member.

The formalities track the triggering event. A share transfer must be recorded in a written deed, filed at the registered office (or served on the company), and made enforceable against third parties by filing the amended articles at the register. Where the event is a capital increase or a partial sale, the same logic applies: carry out the operation, then update and file the articles to show the new membership. No transformation resolution is needed, because there is no transformation.

The point that catches founders out is the approval clause. A single shareholder who never expected a partner may not have inserted one - and without it, they cannot control who enters the company. A subscriber's spouse, or a subscriber's heir, may join with no way to block them; inserting an approval clause in extremis may come too late, because once new shareholders hold enough votes they can resist the amendment. This is why the EURL's articles should carry the approval clause and the multi-member rules from day one, ready for the day a shareholder joins.

The tax shift when an EURL becomes a SARL

The formalities are light, but the tax change is the real substance. An individual-owned EURL is taxed by default as a partnership - profits taxed in the shareholder's hands under income tax. When it becomes a multi-member SARL, that SARL is, in the ordinary case, subject to company tax: from the change, the former single shareholder stops being liable to income tax on the company's profits, the company's profits are taxed under the capital-companies regime, and the shareholders are then taxed only if the company distributes - dividends falling into the investment-income category.

That shift has a sting for a shareholder who worked in the EURL. Moving from the partnership regime to company tax transfers the shares out of the professional patrimony into the private patrimony, which triggers a professional capital gain. The gain crystallised by that change of tax regime can, in the right conditions, benefit from a deferral of taxation - but it needs to be identified and managed, not discovered after the event. Interest on a loan taken to buy the shares also stops being deductible once the company moves to company tax.

None of this is a reason to avoid bringing in a shareholder - growth often needs one - but it is a reason to plan the tax before the event, not after. Registration duty on the share transfer (broadly 3% after an allowance) and the change of regime interact, and the deferral reliefs have conditions. Getting the sequence and the paperwork right is what keeps a welcome new shareholder from turning into an unwelcome tax bill.

From SARL to EURL: when shareholders leave

The reverse move happens when all the shares end up in one hand, and again several events can bring it about. The most common is one shareholder buying out all the others. A death can do it - the classic case being a SARL between two spouses where one dies leaving all the shares to the survivor. And a capital reduction can create a one-member company, by letting a shareholder withdraw: either through a buy-back of their shares using company funds, or by giving them company assets in kind in exchange for cancelling their shares.

That capital-reduction route deserves a note, because it is a deliberate way to engineer a departure rather than an accident of a sale. Where the company has the reserves or the assets, buying back and cancelling a leaving shareholder's stake removes them cleanly and leaves the remaining shareholder holding everything. It has to respect the ordinary rules on capital reductions - the creditor-protection safeguards in particular - but as a means of moving from a SARL to an EURL by letting one side exit, it is a well-established tool.

Crucially, concentrating all the shares in one hand does not expose the company to judicial dissolution. The general rule that lets an interested party ask a court to dissolve a company reduced to one member does not apply to a SARL - the SARL continues as an EURL. The sole shareholder can still decide a voluntary dissolution if they want to end the company, and the consequences of that differ sharply depending on whether the single shareholder is an individual or a legal person (discussed below). But the one-member state itself is stable and lawful.

As with the other direction, no transformation is involved and the formalities are only those inherent in the event - the share transfer or the capital reduction - with a matching update of the articles. The company continues smoothly as an EURL, now governed by the single-shareholder rules: the shareholder exercises the powers of the meeting, records decisions in a register, and picks up the loan-and-guarantee prohibition and the other one-member features.

The tax shift when a SARL becomes an EURL

Here the tax change runs the other way, and there is a trap to avoid. When all the shares of a SARL are gathered in the hands of a single individual, the company moves in principle from company tax to the partnership regime - an income-tax footing. For a company that has been operating under company tax, that automatic switch can be unwelcome and disruptive.

The law provides the escape: the single shareholder can opt for company tax within three months of the shares being gathered in one hand. Making that option in time renders the passage into an EURL tax-neutral - the company stays under company tax and continues as it was, now as a one-member company. Miss the three months, and the company reverts to the partnership regime by default, with all the personal-tax consequences that follow.

Where the single shareholder is a legal person, the analysis is different - a company-owned EURL is compulsorily subject to company tax, so there is no partnership drift to guard against. The practical rule for the common case of an individual buying out their co-shareholders is simple and strict: if you want to keep company tax, diarise the three-month option and exercise it. This is one of the clearest examples of a light formality (the buy-out) carrying a hard tax deadline behind it.

The two directions side by side

The table sets the two conversions against the criteria that matter - what triggers them, the formality, and the tax consequence - so the shape of each is clear at a glance.

Read across, the symmetry is clear: the mechanics are identical and light in both directions, and the substance - the thing that needs planning - is the tax regime and, for the EURL→SARL direction, the control of who joins.

If the single shareholder decides to close instead

Sometimes shares gather in one hand not as a step toward continuing as an EURL but as a prelude to closing the company. The sole shareholder can decide a voluntary dissolution - and the consequences depend entirely on who the shareholder is. This is not a choice the shareholder makes freely; it is dictated by their status.

Where the single shareholder is an individual, the law excludes universal transmission: the company must go through a normal liquidation. The shareholder loses the manager role but can appoint themselves liquidator; in practice there is no sharing, and the liquidation surplus and available assets return to the shareholder once the debts are cleared. The dissolution is enforceable against third parties only from its publication, and a closing notice is published.

Where the single shareholder is a legal person, the opposite applies: the dissolution triggers a universal transmission of the company's assets and liabilities to the parent, without any liquidation, once the creditors' objection period has run. Creditors have thirty days from publication to object, and a court then either rejects the objection or orders repayment or guarantees. Knowing which regime applies - liquidation for an individual, universal transmission for a company - is essential before deciding to close a one-member SARL.

Planning the conversion well

The through-line of both directions is that the legal move is easy and the tax move is not. So the planning effort belongs in two places. First, in the articles: draft them from the outset to work as both an EURL and a classic SARL, with an approval clause and the multi-member governance rules, so that a joining shareholder does not force an unwanted change or an unwanted co-member. Second, in the tax timing: identify the change of regime before the event, manage any professional gain and its deferral on the way up, and diarise the three-month company-tax option on the way down.

Registration duty, loan-interest deductibility and the reliefs all interact with these moves, and the right sequence can make the difference between a neutral conversion and an expensive one. Because the triggering events - a sale, a capital change, a divorce, a death - are often driven by life or business rather than tax planning, the tax consequences tend to arrive whether or not anyone prepared for them. The value of advice is in getting ahead of the event so the conversion lands on your terms.

Handled well, the EURL and the SARL give a founder remarkable flexibility: start alone, bring in one or more partners when growth needs them, and return to a single owner again if they later leave - all within one continuous company that never has to be dissolved or re-created. The form bends to the business rather than the business bending to the form, provided the articles and the tax treatment are set up in advance to let it happen.

The share-transfer formalities in detail

Whichever direction you are moving, a share transfer is often the triggering event, and its formalities are worth getting right because they decide when the change becomes effective against outsiders. The transfer must be recorded in a written deed - a private agreement or a notarised one. A private deed is then filed at the registered office against a deposit receipt issued by the manager, or served on the company by a court officer, so that the company itself is bound.

Enforceability against third parties comes from a further step: filing the amended articles at the trade and companies register. Until that filing, outsiders are entitled to treat the old position as unchanged, which matters for anyone dealing with the company on the strength of who its shareholders are. Sequencing these steps correctly - deed, then notice to the company, then register filing - is what makes a transfer clean rather than contestable.

On the money side, a share transfer generally attracts registration duty of 3%, applied to the value of each share after an allowance calculated from the ratio between €23,000 and the total number of shares. The duty, the deed and the filing all sit alongside the tax-regime change, so a transfer that looks like a simple signature is in fact several interlocking steps. Handling them together, rather than one at a time, avoids the gaps that later cause disputes.

Death and the continuity of the company

Death is one of the events that can move a company in either direction, and it is worth understanding on its own because it is rarely planned for. In a two-member SARL - classically, a company between spouses - the death of one member leaving all the shares to the survivor gathers the shares in one hand and the SARL continues as an EURL. In the other direction, the death of a single shareholder who leaves several heirs brings multiple members in and turns the EURL into a classic SARL.

A reassuring default underpins both: the death of the single shareholder does not, by itself, dissolve the company, unless the articles say otherwise. The business does not stop on a death - one of the EURL's advantages over a sole trader, whose activity can end with them. The shares pass under the ordinary rules of succession, and the company continues in whatever membership the succession produces, with the articles updated to reflect it.

This is exactly why the articles should anticipate succession. Whether a death will leave the company one-member or multi-member is not always within anyone's control, so statutes drafted to work in both states - with an approval clause governing who may end up a shareholder - spare the heirs a governance scramble at the worst possible time. Planning the succession of the shares, in the articles and alongside a will, is part of running an EURL or a small SARL responsibly.
