The French tax declaration campaign for the year 2026, covering incomes earned in 2025, is set to commence on April 9, as announced by the Directorate General of Public Finances (DGFiP) to Le Figaro. This announcement confirms previous information and aligns with the traditional scheduling of the campaign starting on the second Thursday of April. The complete schedule for the declarations will be released later, providing specific dates for various procedures.

The deadlines for tax declarations will differ depending on the taxpayer's department of residence and whether they are filing online or through paper forms. As is customary, these deadlines will span from the end of May to the beginning of June, which allows taxpayers some flexibility in completing their declarations based on their specific circumstances. The authorities have reiterated their commitment to ensuring that the process is clear and accessible for all taxpayers.

In notable changes, the tax rates for the upcoming declarations will be indexed to inflation since 2019, aiming to provide some relief and fairness amid rising costs. This adjustment attempts to mitigate the impact of inflation on taxpayers, although further details on how this will be implemented will be necessary to understand the full implications for individual taxpayers and the overall tax system in France.
