Verified 01 August 2025 - Directorate of Legal and Administrative Information (Prime Minister)

Do you want to grow your savings securely and without paying taxes? You can open a sustainable and solidarity development booklet (LDDS), formerly called Codevi. It is an investment whose interest rate is set by the government, taking into account inflation. Your money remains available and you can make a withdrawal if needed. We present you the information to know.

Major

Any adult who has tax domicile in France can open a sustainable and solidarity development booklet (LDDS).

Minor

A minor resident for tax purposes in France may open a sustainable and solidarity development booklet if he has personal income and is no longer attached to his parents' tax household.

It is forbidden to hold several LDDS at the same time. Indeed, the number of LDDS is limited to one per person, and to 2 per tax home.

The bank that receives a request to open LDDS must inform the customer of the prohibition to hold 2 LDDS and ask him if he already holds an LDDS in another institution or not.

The bank can give you a withdrawal card, but you can only use it at ATMs in its network.

Transactions made on the LDDS are free: opening, deposit, withdrawal and closing.

You can supply your sustainable and solidarity development booklet by check, cash payment at the counter or by transfer from a current account.

The annual interest rate is 1.7%.

Calculation of interest

Interest is calculated on 1er and the 16th of each month.

The sums deposited produce interest if they are placed in full fifteen.

At December 31 of each year, the accumulated interest for the year is added to the principal. The addition of interest on December 31 may increase the value of the booklet beyond €12,000.

You can use the money saved on your LDDS to make a donation to a social and solidarity economy company.

The bank with which you have opened your booklet must offer you a list of at least 10 companies of the social and solidarity economy each year.

Once you have communicated the name of the chosen companies and the amount of the donations, the bank can make the payment directly from your LDDS.

Banks must use the money collected under the LDDS to provide loans to improve the energy performance of housing, at attractive rates.

What works are eligible?

This is energy-saving work carried out in individual or collective dwellings that serve as a main or secondary dwelling, or that are rented.

Example :

Thermal insulation materials, temperature control devices, power generation devices

It is the banks that check the eligibility of the work from the estimates.

Beneficiaries

It is not necessary to have an LDDS to benefit from the sustainable development loan.

This loan can be granted to individuals, condominiums and building professionals, to carry out certain works.

Amount, rate and term of the loan

Banks freely set the amount and duration of the loan, depending on the elements of the file: nature of the work and creditworthiness of the borrower.

They have an obligation to offer attractive rates, but there are no government-imposed rates.

The conditions for granting the loan may therefore vary from one bank to another.

Interest is exempt from income tax and social security contributions.

To close your LDDS, by simple letter or by visiting your bank, you must specify the following information:

  • LDDS References
  • Account number where the amounts remaining on the booklet must be deposited

If the LDDS closes during the year, interest on the period since the beginning of the year is credited on the closing day.

If the LDDS holder does not contact the bank holding the LDDS, this savings account is considered as inactive. The bank has an obligation to hold the funds for a certain period of time. But after this period, she will have to close the account and transfer the funds to the Caisse des Dépôts.

It is possible to request to recover the funds using the online service Ciclade:
