Following the completion of the corresponding ratification processes, the tax information exchange agreement (TIEA) with Belize came into force on 13 October 2016 and the one with Grenada on 21 December 2016. The agreements will be applied from 1 January 2017.

On 4 April 2012, the Federal Council decided to enter into administrative assistance agreements upon request in accordance with the international standard not only in the form of double taxation agreements (DTAs) but also via TIEAs. In principle, DTAs and TIEAs are equivalent instruments for concluding an administrative assistance clause in accordance with the international standard. Unlike DTAs, which are aimed primarily at avoiding double taxation and therefore contain other material provisions, TIEAs merely govern the exchange of information upon request.

To date, Switzerland has signed 54 DTAs and 10 TIEAs that are in line with the international exchange of information standard, and of these, 49 DTAs and 9 TIEAs are in force.
