What is the difference between IR and IS?
✅ In brief
IR (impôt sur le revenu) and IS (impôt sur les sociétés) indicate who bears the tax on profit: the entrepreneur or the company.
🧭 What you need to know
- Under IR, the result may be taxed at the level of the person concerned.
- Under IS, the company pays tax on its profits.
- Some forms are subject to IS by default; others may fall under IR or offer options.
- The choice can affect remuneration, dividends and cash flow.
🛠️ How Leegal supports you
- Leegal helps you understand the wording shown during the creation process and prepare a clearer file.
- The flow can organize information, documents and points to watch, but it does not replace a personalized review.
- If your situation is specific, it is still preferable to ask a chartered accountant, a lawyer or another qualified professional for advice.
🔎 Points to check
- The legal form chosen.
- The planned remuneration.
- The personal situation of the company officer or associés.
- Advice from a chartered accountant before choosing a tax option.
⚖️ Limits to know
- Leegal is not a law firm or an accounting firm.
- Leegal explains the options and helps prepare formalities, but does not choose for you.
- Tax, social security or personal asset consequences can depend on your actual situation.
📌 Key takeaway
IR and IS are not just two tax labels: they change the way profit is taxed.
