Q: What is the deadline for filing my French tax return in 2025?

A: If you’re submitting a paper return, which is mandatory if this is your first time filing, the deadline is Tuesday 20 May 2025 at 11.59pm.

For online returns, deadlines vary by department:

  • 01-19: Thursday 22 May 2025.
  • 20-54 (including 2A and 2B): Wednesday 28 May 2025.
  • 55-974/976: Thursday 5 June 2025.
  • Non-residents: Thursday 22 May 2025.

Those living in Paris (department 75) must file by Thursday, 5 June 2025.

Online filing is obligatory if your primary residence has internet access and you’re not a first-time declarant. The online portal opened on 10 April 2025 and late submissions will accrue penalties.
