On June 22, DOJ voluntarily dismissed its summons enforcement action against UBS after the bank produced all Singapore-based records responsive to an IRS summons.  The IRS administrative summons was served on UBS for all records pertaining to accounts held by Ching-Ye “Henry” Hsiaw in relation to an investigation into offshore tax evasion.  Announcing the dismissal, Acting Assistant Attorney General Caroline D. Ciraolo of the Tax Division explained that to detect offshore tax evasion, “[o]ne critical component of that effort is making sure that the IRS has all of the information it needs to audit taxpayers with offshore assets.”  Ciraolo also encouraged taxpayers underreporting their income through offshore assets to come forward before the IRS comes looking for them.
