2025 Income Tax: Get an estimate of how much you'll have to pay

As of April 10, you will be able to access the online service of the tax site to file your tax return of the year 2024. You must make this declaration even if you have received low resources (or no resources).

You can already use the official simulator to calculate your 2025 income tax for 2024, for an indication of the amount of your tax and your reference tax income. This simulator takes into account new income brackets, which each correspond to a different tax rate.

The simulator can only be used if you live in France. You can use:

• the simplified simulator model, if you only have to declare salaries or retirement pensions, for example, and deduct the most common expenses (alimony, childcare expenses, donations to associations and organizations of general interest, etc.);
• the full simulator model, if you also have to report income from commercial, liberal or agricultural activities, investments in overseas departments and regions, overall deficits, etc.
