Registered office and tax domicile: stop confusing them

“If I domicile my business at a given address, do I change my tax domicile?” This is one of the most common questions, and it rests on a misunderstanding: in business language, the word to domicile means ‘to give a company an address’, not ‘to declare one’s tax domicile’. Behind this confusion lie, in reality, three distinct ideas that can perfectly well sit at three different addresses. Telling them apart avoids two costly mistakes: believing that a business address shifts your taxation, and believing that it necessarily exposes your home.

Three ideas you should not confuse

• The registered office: the administrative and legal address of the business, the one shown on the register, on the Kbis, on invoices and on contracts. It is a company-law idea.
• The place of business (or establishment): the place where the activity actually takes place. This is what governs the real taxation of the activity.
• The tax domicile: that of the person (you, the director, the partner), the place where you are taxed on your income. It is never a mere administrative address.

A concrete example shows that they come apart without difficulty: a consultant may carry out their activity in Tours (place of business), set their company’s registered office at a business address in Bordeaux (registered office), and live with their family in Angers (tax domicile). Three addresses, three ideas, three sets of rules.

The registered office is the company’s address, not a tax address

Domiciling a business, according to the official definition, “means giving an administrative and legal address to a business as a legal person”. This address determines the competent court and the place of your formalities, and it appears on all your documents. But it falls under company law, not tax law: the registered office is not, in itself, a tax factor.

Where is your business actually taxed?

For tax purposes, it is economic reality that counts, not the declared address. Corporation tax (impôt sur les sociétés) is assessed at the place of the main establishment, and the tax authorities may also look to the place of effective management. The registered office is only one possible connecting factor, not the governing criterion. And the corporation tax rate (IS: 25 %, or 15 % up to 42 500 € of profit for eligible SMEs, meaning a turnover below 10 million euros, fully paid-up capital held at least 75 % by individuals) is set by law and the same everywhere in France: moving your registered office to a “cheaper” municipality does not change it.

The business property contribution (cotisation foncière des entreprises, CFE) is due where the business holds premises and carries out its activity. The tax authorities treat the address of a business-address provider as the place of taxation only if the taxpayer has no other professional premises. As soon as a real place of business exists, that place prevails. Domiciling your registered office therefore does not “shift” the CFE to the business address (we cover the CFE in detail elsewhere).

Your tax domicile is yours, not your company’s

Tax domicile is an idea that applies to individuals. You are tax-domiciled in France if just one of these criteria is met (Article 4 B of the code général des impôts, the French General Tax Code): you have your home or your main place of stay there; you carry out your main professional activity there; or you have the centre of your economic interests there. The tax authorities state it plainly: tax domicile does not depend on a mere administrative address.

For an auto-entrepreneur or an entreprise individuelle (the French self-employed and sole-trader statuses), profits are taxed under income tax and included in your personal return (the tax household). The return therefore follows the person, at their home, not the company’s address. Domiciling your activity at a third-party address changes neither your tax domicile nor the tax office with which you declare your income.

For a company director, the principle is the same: your remuneration and your dividends are taxed on your personal return, according to your place of residence, regardless of the company’s registered office. The registered office locates the business; your tax domicile is yours.

No, domiciling your business does not lower your taxes

Let us say it plainly: a business address is an address solution, not a tax-optimisation tool. It does not change your tax domicile and does not move the real place of taxation of your activity, which follows where the activity is actually carried out. Corporation tax, for its part, is national: domiciling it here or there does not change the rate. One honest qualification: if you have no professional premises, the CFE is due at the place of your business address, in the form of a minimum charge whose scale is set by each municipality and therefore varies from one to another. The effect remains marginal and concerns neither tax on profits nor your income tax. Beyond this specific case, be wary of any pitch promising “domicile here to pay less”: that would be inaccurate. What a business address gives you is a clear professional address, separate from your home, and simplified formalities.

What if I live abroad?

The logic also holds internationally. A director who lives abroad and domiciles their French company in France remains, if they meet none of the Article 4 B criteria in France, a non-resident for tax purposes: they are taxed in France only on their French-source income, subject to tax treaties, which take precedence. The French company, for its part, keeps its registered office and its taxation in France. Beware, however, of the notion of a permanent establishment when the activity is genuinely run from abroad, a topic we address in a dedicated article.

Beware the “letterbox” registered office with no substance

While a business address is perfectly legal, a purely fictitious registered office, used to relocate taxation artificially, is open to challenge. In company law, the real seat prevails over the declared one: you cannot hide behind a fictitious address if management is elsewhere. In tax law, the authorities may look to the place of effective management, and an arrangement with a mainly tax-driven purpose may be recharacterised as an abuse of law. A business address is legitimate when it corresponds to a genuine address of attachment for your business, not to a screen meant to conceal a different reality.

In short: the registered office is your company’s address, the place of taxation follows your real activity, and the tax domicile is yours. The three are independent. Domiciling your registered office clarifies and stabilises an address; for tax matters, your chartered accountant remains the right contact. At Domisiège, the Tours address comes precisely with access to the chartered accountant of Épiphyse Conseil.
