Verified 01 January 2026 - Entreprendre Public Service / Directorate of Legal and Administrative Information (Prime Minister)
A company settled in a defense restructuring zone (DRZ) may benefit from several tax and social exemptions.
You can consult the official list of DRZs to find out if your company is in a relevant territory.
Conditions for exemption
In order to benefit from the income tax (IR) and business tax (IS) exemptions, the company must set up a new activity and comply with a condition of headcount or turnover.
The exemption rules are different depending on whether the company has a new activity or exercises new and non-sedentary activity (i.e. outside the business premises, mainly at the customers' premises).
Warning
Repossessions of existing activities in the ZRD and residential rental activities are not eligible for the exemptions.
New Activity
In order to benefit from the exemption, the company must set up a new activity, previously non-existent in the ZRD.
The exemption shall be reserved for new or existing companies which create new activities in the DRZs for a period of six years starting from:
- From the date of publication of the order delimiting the ZRD
- If the date of this order is later than the activity, from 1er January of the year preceding the year for which the ZRD is recognized. For example, if the municipality where the activity is carried out is recognized as ZRD in 2020, then the period for benefiting from exemptions begins on 1er January 2019.
The new activity must relate to one of the following areas:
- Industrial, artisanal or commercial,
- Liberal if it is practiced in a business subject to the IS,
- Rental of professional buildings equipped with their equipment (examples: factory with manufacturing machines, restaurant with kitchen and equipment for the public, warehouse with storage and shipping equipment).
New and non-sedentary activity
In addition to the conditions associated with the new activity, the company that has a non-sedentary activity but which is located in a DRZ must also comply with one of the following 2 conditions:
- Employ at least one full-time permanent employee who performs his duties in the premises located in the ZRD (no business travel outside the ZRD)
- Achieve at least 25% of its turnover excluding VAT from customers located in the ZRD
If part of the activity is carried out outside the ZRD (taxis, building trades, personal services activities), the company is entitled to tax exemption only on its profit made in the ZRD (office, workshop, etc.).

The exemption from income tax or business tax is total for 5 years from the start of activity in the area.
For the following 2 years, the exemption is equal to:

The period must therefore include the current fiscal year, as well as the 2 previous fiscal years. Compliance with this ceiling shall be assessed at the time of the granting of each new de minimis aid.
