More than 100 HM Revenue and Customs (HMRC) officers searched business premises in Birmingham and further addresses in Coventry, Worcestershire, Northumberland, Buckinghamshire and Northern Ireland. Officers seized computers, other digital devices, as well as business and personal records.
A spokesman from HMRC’s Fraud Investigation Service said: “Those that enable, promote or facilitate tax fraud are firmly in our sights and we currently have more than 200 such suspected enablers under criminal investigation.
“We are keen to protect the public from those who devise and market fraudulent schemes which at best do not work and at worse mean that people could end up being involved in fraud.
“People need to think extremely carefully before they enter into any scheme that claims to significantly lower your tax bill. If something looks too good to be true, then it almost certainly is. HMRC’s advice is firmly to steer clear.”
All five people arrested will be interviewed under caution by HMRC officers. A sixth person, a 39-year-old woman from Birmingham, will attend a voluntary interview under caution.
A spokesman said the interventions are the latest in a series where HMRC is investigating fraud offences related to disguised remuneration tax avoidance schemes.
No further information can be released at this time as investigations are ongoing.
