Declaring your income and assets

As a member, you must declare your income and/or assets every year to determine the amount of your contributions.

How do I obtain the income and assets declaration (I+A)?

  • Each year, in December, you will receive your I+A either by e-mail or by post

  • If you have not received your I+A, please contact us by e-mail or by post

  • I+A declarations are processed in order of arrival

How do I complete the I+A?

  • According to your professional situation abroad: with or without gainful employment

  • If you have worked for less than 9 months or at a rate of less than 50%, please provide us with your income and your assets

  • A copy of the supporting documents must be enclosed with the I+A

How do I submit the I+A?

Online: via the eCdC portal

  • Only those insured under the voluntary OASI/DI scheme registered with a Swiss consular representation have access to the eCdC portal.
  • Students insured under the compulsory OASI/DI/EO scheme do not have access to the eCdC portal.
