A good way to get rid of taxation issues when it comes to Liechtenstein bank accounts:  The Liechtenstein Disclosure Facility (LDF) offers a means for UK residents with
unpaid tax to make disclosures to HM Revenue and Customs (HMRC) of tax irregularities where monies are (or have been) held in bank accounts anywhere in the
world, or where overseas property has been bought using undeclared monies, or where offshore companies may have been used to evade tax.
