In France, citizens pay several types of taxes to finance public services. Understanding these taxes and how they are calculated will help you manage your budget better and avoid surprises.
What is a tax?
A tax is a mandatory contribution paid to the federal government or local authorities. In France, there are several types:
- Income tax : taxation of’money you earn.
- Value added tax (VAT) : paid when purchasing goods and services.
- Property tax : paid by property owners.
- Residential tax : paid by occupants of a dwelling (trend toward gradual elimination for primary residences).
- Specific taxes : fuels, tobacco, etc.
💡 These taxes are often collected automatically or included in the purchase price, unlike the’income tax which is declared and calculated annually.
Understanding the taxes is never straightforward, as each country has its own rules. There is a lot of talk about income tax rates in the United States, because they are clear, central, and widely publicized. Everyone refers to the same federal scale. In France, the system is different, more complex, and individualized.
The principle of the progressive tax scale
✅ In France, income tax is based on a progressive scale. This means that your income is divided into brackets, and each bracket is taxed at a different rate.
👉 This mechanism leads to what is known as marginal tax rate. This is the percentage applied only to the highest portion of your income, not to your total income.
Progressive tax scale applicable in 2025 (to 2024 income)
The following table shows the current tax bracket for one tax share:
| Annual income bracket | Applied rate |
|---|---|
| Up to $11,497 | 0 % |
| From $11,498 to $29,315 | 11 % |
| From €29,316 to €83,823 | 30 % |
| From €83,824 to €180,294 | 41 % |
| Over €180,294 | 45 % |
⚠ Since 2019, the tax is directly collected on salary or pension, but the calculation remains based on the annual taxable income.
📌 The system also takes into account the family quotient, meaning that if two people have the same income but their family situations are different (single or parents with children), they will not pay the same amount of tax. It adjusts the tax based on how much money you earn and the composition of your household.
Steps for calculating income tax
Follow these steps to find out how much you need to pay.
Step 1: Determine your net taxable income
This is the total household income minus authorized tax deductions: alimony, professional expenses, etc.
Example : a single person earns €38,000 per year and can deduct €3,000 in professional expenses, so their net taxable income will be: 38,000 – 3,000 = €35,000.
Step 2: Apply the family quotient
To take family circumstances into account, you divide the net taxable income by the number of tax shares.
Example : the same person is single = 1 share. Income per share = 35,000 ÷ 1 = €35,000.
If she had one dependent child = 1.5 shares. Income per share = 35,000 ÷ 1.5 = approximately €23,333.
Step 3: Apply the progressive scale
You calculate the tax on each income bracket according to the official tax scale.
Example : for 1 share with €35,000
- Slice 1 : 0% on the first €11,497 = €0.
- Slice 2 : 11% on the difference between €29,315 and €11,497 (i.e., €17,818): €17,818 x 11 % = €1,959.98.
- Slice 3 : 30% on the difference between €35,000 and €29,315 (i.e., €5,685): €5,685 x 30 % = €1,705.50.
Total gross tax :
0 € + 1 959,98 € + 1 705,50 € = 3 665,48 €
Step 4: Deduct tax credits and reductions
You deduct any tax benefits to obtain the final tax amount.
Example : this person benefits from a tax credit of €500: net tax = 3,665.48 – 500 = 3 165,48 €

What is a marginal tax rate?
🎯 The marginal tax rate corresponds to the percentage applied to the highest portion of your income.
In other words, even if you earn a lot, you don't pay this percentage on your entire salary, but only on the portion that exceeds the previous bracket.
How does the marginal tax rate in the United States differ from that in France?
As in France, the marginal tax rate in the United States refers to the percentage applied to the last bracket of taxable income.
The difference is that this rate is highly publicized and that it has influence over the financial decisions of American taxpayers.
