Association under the 1901 law or the 1905 law: which status for a mosque?
This is the very first decision of a mosque project, and one of the most defining. The status chosen determines what the association will be able to do, the support it will have access to and the obligations it will have to meet. Here is what you need to compare the two paths calmly.
The scholarly tradition of classical Islam pushed the demand for rigour very far, going so far as to verify the chain of transmission, the isnad, of every piece of knowledge reported. To choose a clear framework is to place your project within that same demand.
Two frameworks, two logics
The association under the 1901 law
This is the most flexible framework. Its purpose can be broad and mix worship with cultural, educational or social activities. Its founding is simple and quick. It is by far the most widespread: to date, more than nine mosques in ten operate under the 1901 law. Its limit lies in the advantages reserved for religious associations, which it does not open automatically, starting with the tax receipt and the long lease.
The religious association under the 1905 law
Governed by title IV of the law of 9 December 1905, it has an exclusively religious purpose: it cannot directly carry cultural or social activities. In exchange for this specialisation, it opens the advantages most useful to a mosque project. The law of 24 August 2021 reinforced its obligations, notably the declaration of religious character to the prefect, to be renewed every five years.
The comparison
| Criterion | 1901 law | 1905 religious association |
|---|---|---|
| Purpose | Broad, mixed activities possible | Exclusively religious |
| Tax receipt for donations | Delicate, subject to general-interest conditions | Yes (article 200 of the tax code) |
| Long lease with a town | No | Yes (article L.1311-2 of the CGCT) |
| Loan guarantee by a local authority | Possible as a local grouping | Yes |
| Minimum members | 2 | 7 adults |
| Obligations since the 2021 law | Aligned if a mixed association carrying out worship | Declaration to the prefect every 5 years, accounts, foreign donations |
The case of « mixed » associations
Many mosques under the 1901 law in fact carry out worship while running other activities. The law of 24 August 2021 aligned part of their obligations with those of religious associations: an accounting distinction for religious activities, the declaration of foreign funding, and the possibility for the prefect to order such an association to declare itself as religious. This point deserves attention, because it brings the two regimes closer on the ground.
How to decide
If your priority is to raise tax-deductible donations and to consider land support from the town, the 1905 religious association is the natural route. If you value carrying cultural or social activities too, the 1901 association keeps its flexibility, even creating a religious association alongside it for the worship side. In every case, the drafting of the statutes must reflect this choice with care. The Legal area and the assessment help you frame the decision. For guidance in three questions, suited to your project, our tool Status & founding guides you toward the right framework and its first steps.
Frequently asked questions
Should a mosque be a 1901 or a 1905 association?
Both are possible, and today more than nine mosques in ten operate as an association under the 1901 law. The religious association of the 1905 law opens up advantages such as the tax receipt, the long lease or the loan guarantee, but requires an exclusively religious purpose and heavier obligations.
What are the advantages of the 1905 religious association?
It can issue tax receipts to its donors (article 200 of the general tax code), benefit from an administrative long lease with a town, have a loan guaranteed by a local authority, and hold income-producing buildings received by gift or bequest. In return, its purpose must be exclusively religious.
What obligations did the 2021 law add?
The law of 24 August 2021 requires religious associations to declare their religious character to the prefect and to renew it every five years, a minimum of seven adult members, more transparent accounts, the declaration of foreign donations above 10,000 euros, and a governance protected against takeovers.
Can an association under the 1901 law issue tax receipts?
It is delicate. Article 200 of the general tax code expressly targets religious and charitable associations. An association under the 1901 law whose purpose is purely religious does not automatically fall within the categories of general interest that open the right to a tax receipt. It is better to make this point watertight with a lawyer, or even through a tax ruling.
Can you change status later?
A structure can be made to evolve, for example by creating a religious association alongside a 1901 association, or by declaring itself religious. The prefect may indeed order an association whose real purpose is worship to declare itself as religious. Legal support is recommended for these transitions.
