              OOP Case
          Appetizer
              The French electronic tax filing system allows citizens to opt-into the re-use of their data by the French tax authority. If citizens have already submitted submitted personal data to other public administrations, the tax authority will not ask for this information a second time.  
          OOP aspect
              Through data exchanges between the French public administrations, the citizens only have to provide their data once and can file their taxes quicker and with less administrative burdens. 
          Short summary
              There is a lot of information held by the tax authorities that citizens need when they are applying for various public services. That is ineffective because the exchange between different public administration is already possible and has proven its effectiveness. This will be reformed as part of the French programm "Dites-le-nous une fois". Citizens no longer have to give information to the public authorities that is held by the tax authorities if they have signed an agreement. These are e.g. information about the familiy situation, the number of people living in the household or the tax income. 
The pilot phase will begin with the following partners: The ministry of education and the cities Paris, Lyon and Marseille.
