The U.S. Treasury is reportedly planning to enter into negotiations with Israel and Switzerland for the revision of the current income tax treaties with the respective countries, which would be the third revisions to the treaties. The 1975 tax treaty with Israel has been amended through protocols signed in 1980 and 1993, while the 1996 tax treaty with Switzerland has been amended through an exchange of notes in 1997 and a protocol signed in 2009. Details on any further revisions will be published once available.
