The sale of shares is a common legal transaction in the life of a company. It entails significant tax consequences, in particular the application of registration duties. These duties represent a compulsory tax that applies when ownership of the shares is transferred. Understanding the calculation mechanism and the associated tax obligations enables you to anticipate the tax cost of the operation and avoid penalties.

The tax treatment of share sales varies according to the nature of the company and the characteristics of the transaction. A precise knowledge of the applicable rules is essential to secure your transaction.

What are share transfers and registration fees?

The transfer of shares refers to the transfer of ownership of shares held in a partnership or limited liability company. This operation involves a transferor who passes on his rights and a transferee who acquires them.

Registration fees are a tax levied by the tax authorities when the deed of sale is registered. They apply mainly to shares in SARLs, non-trading companies and general partnerships. The General Tax Code strictly regulates this tax system.

Registration of the deed with the relevant tax office makes the transfer enforceable against third parties. This compulsory formality guarantees the legal certainty of the transaction, and enables the tax authorities to collect the tax due.

Rates and calculation of registration fees

The general rate of registration duty is 3% of the sale price, collected in full by the State since the abolition of the departmental portion in 2020. This rate is applied after deduction of an overall allowance of 23,000 euros, calculated in proportion to the percentage of shares sold in relation to the total share capital. The calculation formula is as follows Applicable allowance = €23,000 × (number of shares sold / total number of shares). These provisions are set out in Articles 730 and 732 ter of the French General Tax Code. Please note: this allowance does not apply to sales of shares in companies with a preponderance of real estate assets, which are subject to a specific regime.

The tax base corresponds to the price stipulated in the deed of sale, or the actual market value if this is higher. The tax authorities may question the declared price if they consider it to be manifestly undervalued, in particular on the basis of comparative data or the book value of the company's assets.

Example of a practical calculation

Let's take the case of a limited liability company with a total of 1,000 shares. A partner sells 100 shares for 150,000 euros, i.e. 10% of the share capital. Registration duties are calculated by applying the allowance proportionally to the share sold:

• Sale price: 150,000 euros
• Percentage of shares sold: 100/1,000 = 10%.
• Proportional allowance: 23,000 euros × 10% = 2,300 euros
• Tax base: 150,000 - 2,300 = 147,700 euros
• Registration fees due: 147,700 × 3% = 4,431 euros
• Fees and formalities: approximately 50 to 100 euros
• Total cost of operation: approx. 4,480 to 4,530 euros

This amount must be paid when the deed is registered. It is essential to calculate the proportional allowance correctly to avoid any errors in the tax return. If all the company's shares were sold (100%), the 23,000 euro allowance would apply in full.

Declaration obligations and registration formalities

The deed of sale must be registered with the corporate tax department within one month of signature. This deadline is a mandatory legal requirement, and failure to meet it will result in penalties.

The documents required include the original deed of assignment, a specific declaration form and payment of duties. Depending on the company's articles of association, the transfer may be recorded by private deed or notarial deed.

Failure to register on time exposes the parties to substantial financial penalties. Penalties include a surcharge of 10% on the fees due and late payment interest of 0.20% per month. To understand all the consequences, consult our page on failure to register.

Administrative procedure

The registration procedure takes place in several stages. First, you need to complete the Cerfa n°2759 form, which summarizes the details of the transfer. You then submit this form, together with the deed and payment, to the appropriate department.

The tax authorities issue a receipt attesting to the registration. This document proves that you have complied with your tax obligations, and provides legal certainty for the transaction.

Special schemes and possible exemptions

There are a number of exceptions to the standard 3% tax rate on the sale of company shares for valuable consideration. These special arrangements apply depending on the nature of the company, the composition of its assets or the type of transaction carried out.

Preponderantly real estate companies

Sales of shares in companies whose assets are mainly made up of real estate are subject to a specific tax regime that is particularly important to be aware of. A company is considered to have a preponderance of real estate assets when more than 50% of its assets consist of real estate or real estate rights not allocated to operations.

These sales are subject to the property transfer tax stipulated inarticle 726 of the French General Tax Code. The applicable rate is 5%, plus additional municipal and departmental taxes, bringing the actual rate to between 5.09% and 5.81%, depending on the local authority. The 23,000 euro allowance does not apply to these transactions.

Shares in non-trading property companies (SCI) systematically fall into this category, and are therefore subject to this higher tax rate when sold for valuable consideration.

Incorporation and restructuring

Outright contributions of shares to a company benefit from preferential tax treatment at a reduced rate. These transactions, which are not technically transfers but contributions, are subject to a fixed or reduced proportional duty, depending on the case.

Certain restructuring operations (mergers, demergers, partial contributions of assets) may also benefit from favorable tax regimes, or even total exemption, subject to compliance with strict conditions relating in particular to the continuation of the business.

Distinction from gratuitous transfers

It is important to distinguish between transfers for valuable consideration, which are the subject of this article, and gratuitous transfers (gifts and inheritances). The latter are subject to a totally different tax regime, with their own transfer taxes. The Dutreil pact, for example, provides partial exemption from transfer duties on gratuitous transfers of family businesses, but does not apply to transfers for valuable consideration.

Family transfers

Transfers of shares between members of the same family are still subject to 3% registration duty, even when the transaction takes place within a family context. The family relationship between the transferor and the transferee does not affect the tax regime applicable to transfers for valuable consideration.

The tax authorities are particularly vigilant when it comes to family transfers, especially when the sale price appears abnormally low. If the price is significantly lower than the actual market value, the transaction may be partially reclassified as a disguised donation. In this case, the difference between the actual price and the declared price will be subject to gift tax, which is generally higher.

Article 751 of the French General Tax Code specifically governs the valuation of transfers between related parties. The tax authorities may question the valuation used, and apply the abuse de droit procedure, if they can demonstrate that the undervaluation is primarily intended to evade tax. This vigilance justifies a rigorous valuation of the shares transferred, ideally confirmed by an independent expert.

SMEs and holding companies

Contrary to popular belief, there is no specific exemption from registration fees for SMEs when selling shares for valuable consideration. The 3% rate after allowance applies uniformly, whatever the size of the company concerned.

Holding companies, whether active or passive, are also subject to the general registration duty regime when their shares are sold. The fact that they qualify as "animating holding companies" may offer tax advantages in other contexts (Dutreil pact, IFI), but has no influence on the calculation of registration duties applicable to the sale.

The real peculiarities relate to the legal nature of the company: transfers of shares in partnerships (SNC) or certain non-trading companies can benefit from differentiated regimes depending on the composition of their assets, particularly when they include a majority of real estate assets.

Tax Litigation and Registration Duty Appeals

Disputes relating to registration duties frequently concern the valuation of shares sold. The tax authorities may dispute the declared price and make an adjustment if they consider the value to be undervalued.

There are a number of ways in which you can challenge an administrative decision. A contentious claim is the first compulsory step before going to court. This procedure must be initiated within a specific timeframe.

Tax liability and joint and several payment

When selling shares, the transferee, i.e. the purchaser, is usually liable for registration duties. However, tax regulations provide for a solidarity mechanism which makes the transferor liable in the event of default by the transferee. This means that if the transferee fails to pay the duties, the tax authorities can turn against the transferor and demand payment. It is important for the parties to be aware of this tax solidarity. However, a specific clause in the deed of sale may stipulate that the transferor will be liable for payment of duties.

The practical consequences of this solidarity are significant. It is crucial to
verify that all duties have been paid before finalizing the sale transaction. Failure to do so may expose the parties to tax complications later on, with potentially devastating financial implications. Rigorous monitoring of the settlement of these rights is therefore recommended to effectively secure the transaction.
