As reported in the Sunday Times, HM Revenue & Customs are chasing up bills for unpaid tax as part of the crackdown on offshore assets. This includes following up undeclared interest for overseas savings accounts even for accounts relating to those who have died.
The report comments that the Revenue has power to pursue such debts for at least 3 years. It is part of the responsibility of being an executor that during the probate process all such debts are paid, and is a reason why many families pass on the burden to professionals who specialise in this area.
