French Wealth Tax 2026

French Wealth Tax 2026 news: the deadline to file the wealth tax return has been announced.

The tax authorities have published the 2026 real estate wealth tax return filing deadlines, which are the same as the income filing:

For paper tax returns, the filing deadline is 19th May 2026.

For online returns, the following deadlines apply:
•    Non-residents – 21st May 2026
•    Residents of departments 01 to 19 – 21st May 2026
•    Residents of departments 20 to 54 – 28th May 2026
•    Residents of departments 55 to 974/976 – 4th June 2026

The deadline to file the 2026 real estate wealth tax return varies depending on whether you are filing on paper or online.

By way of reminder, since 1 January 2018, the French wealth tax has been replaced by an annual real estate wealth tax, known as Impôt sur la Fortune Immobilière (‘IFI’), which is a tax on real estate whose taxable base is limited to non-business-related real estate assets.

Non-French tax residents are only taxable on French real estate assets, whilst French residents are usually taxable on their worldwide real estate assets. Regardless of your residence or marital status, you are taxed as a single household for IFI purposes, including your spouse and minor children.

You will be liable to pay IFI in 2026 if the net market value of your French real estate assets exceeds €1.3m as at 1 January 2026. French estate agents can help you assess the value of your French real estate.
