Giving up your U.S. passport by renouncing your citizenship now costs you more than ever ($2,350 today, $450 previously). But, this year you could have it cancelled by the IRS as a penalty for your tax delinquency reaching a $50,000 threshold, along with incurring numerous additional fines that continue to be increased.  

If you are a U.S. expat or if you manage a global mobility program with U.S. expats, this 2016 tax filing season could lead to an increase in compliancy issues as the IRS has made great strides in its global information gathering and auditing.

To avoid penalties and fines, clean up your data through your compensation accumulation program and heed these 4 tax tips.
