The reform of withholding tax, implemented since January 1, 2019, does not change the requirement for all taxpayers to declare their income. Therefore, you must file your income tax return for 2024 income between April and June 2025.

When to declare your 2025 IFI? The payment deadline for IFI, like income tax, depends on the payment method.

Paper vs. Online Filing: Is online filing mandatory?

You can still file by paper if:

  • Your primary residence does not have internet access,
  • You live in an area with no mobile service (a “white” zone),
  • You are not familiar with using the internet,
  • Or if this is your first time filing.

In all other cases, online filing is required, regardless of your income level. Failing to file online may result in a fine of 15 euros, starting from the second offense.

Since the implementation of withholding tax on January 1, 2020, income tax payment methods have evolved. From that date, your income tax is deducted as you receive your income.

With the withholding system, you can request, under certain conditions, to adjust your tax rate based on changes in your personal or professional situation. For example:

  • Personal changes: marriage, divorce, birth of a child, etc.
  • Professional changes: unemployment, job change, bonus, salary increase, etc.

These changes are taken into account by the tax authorities, who may adjust your tax rate, which will be communicated to your employer. This ensures that your tax payment aligns with your current situation.

Tax Filing Schedule:

  • January 2025: Taxes for income received in 2024 are automatically deducted. For employees, the withholding rate and tax amount are reflected on the pay slip.
  • April-June 2025: Submit your income tax return, which will define a new withholding rate to be applied to income starting in September.
  • August-September: The tax authorities send the updated withholding rate to employers and pension funds, based on the filed tax return.
