Repayment agent ads have become a common sight in recent years, particularly on social media. You’ll recognise them by their style, usually along the lines of “Do you wear a uniform to work? You could be owed £1,000s from HMRC…” or similar. While many such agents are genuine, the industry has come in for criticism due to practices that are, at best, questionable, e.g. requiring refunds to be made directly to the agent’s account.

More seriously, HMRC is concerned that some of these “firms” are really just a front for money laundering. All tax agents (and other professionals, including accountants and solicitors) must comply with anti-money laundering regulations, including being registered with a supervisory authority. HMRC has found one agent, Tax Credits Limited, to have seriously breached these requirements and ordered the company to cease trading as a repayment agent. It's estimated that around 11,000 individuals had commenced refund claims via the company. HMRC will now write to these individuals to update them. The refunds will be automatically made by HMRC, so you don’t need to do anything if you are one of those affected.
