Furthermore, Austrian clients may possibly still file a voluntary disclosure and for UK clients, a regularisation under the “Liechtenstein Disclosure Facility” (“LDF“) remains possible.  


On the right you find a tool to calculate the one-off payment for the regularisation of the past.


With respect to the mentioned basic elements all the agreements contain similar rules. In respect to important details the agreements differ due to the different tax systems. Further information to specific aspects of the UK Agreement you find on the site “Tax agreement with the United Kingdom”.


What are your challenges?

The tax agreements with Austria and the United Kingdom entered into force on 1 January 2013. As from this date, the investment income and capital gains of Austrian and UK clients of Swiss banks are either subject to the final withholding tax or voluntary disclosure. The banks must ensure that the tax agreements are correctly implemented.


In particular, it has to be verified that the final withholding tax is correctly calculated.
