According to official statistics published by the U.S. Federal Register, a record number of Americans abandoned their U.S. citizenship last year.
The statistics shows that 5,411 people gave up their nationality, an increase of 26 per cent on 2015.
The main motivation for this was identified as tax.
Americans are liable for U.S .tax even if they live abroad. Although in most cases they are unlikely to face a bill because they can offset what they pay to the taxman in their country of residence.
However high earners can face a bill from the U.S. Internal Revenue Service even after they have paid substantial taxes to the Government in their adopted country.
In addition they are expected to file a U.S. tax return every year, irrespective of what they earn.
Americans living abroad are also taxed on any profit they make on selling their home when they live abroad, even if they have no intention of ever living in the United States.
New laws passed in 2010 made life even more difficult for American expatriates.
Those giving up their US nationality include “accidental Americans” who were deemed to be citizens because they were born in the United States, even if they lived their entire life elsewhere.
Boris Johnson, the Foreign Secretary who was born in New York, is among those to have renounced their US citizenship.
