Overview
- The 2024 income tax declaration campaign officially starts on April 10, 2025, and is mandatory for all French tax residents, regardless of income level.
- Paper declarations must be submitted by May 20, while online submission deadlines vary by department, ranging from May 22 to June 5.
- A new online simulator has been introduced to help taxpayers calculate their tax liability and fiscal reference income based on updated brackets indexed to 1.8% inflation.
- Taxpayers claiming the home services tax credit must now specify the type of service provider in a newly required form field, following a 2025 budget amendment.
- Pre-filled paper declarations are no longer automatically sent to those who filed online last year, a cost-saving measure that may cause confusion for some taxpayers.
