More than 80 officers from HMRC searched three private and 12 business addresses in Bath, Bournemouth, Bristol, Berkshire, Exeter, Stroud, Swindon and Yate on Wednesday 4 October.
Colin Spinks, Assistant Director, Fraud Investigation Service, HMRC, said:
“Tax fraud is often thought victimless but it isn’t; the public lose out on vital funds for essential services. We will continue to work with our partners to tackle this crime and ask anyone with information about this kind of activity to contact our HMRC Fraud Hotline on 0800 788 887.”
Computers and business records were seized during the operation. Those arrested were interviewed by HMRC and have been released under investigation. Investigations are continuing.
