There is some – at least, anecdotal – evidence that HMRC have recently been making much greater use of their powers to make directors personally liable for the national insurance debts of their failed companies. The power derives from section 121C of the Social Security Administration Act 1992, which allows HMRC to issue personal liability notices (PLNs) when a company has failed to pay NI contributions and that failure is “attributable to the fraud or neglect of one or more individuals who were, at the time of the fraud or neglect, officers of the company” (known as “culpable officers”).
