It is not always clear what triggers a tax investigation by H M Revenue & Customs however sometimes it is obvious, like an omission picked up by HMRC and at other times it could be random. HMRC also sets up taskforces to target areas that are thought to be at high-risk of tax fraud and you may be operating in one of those areas.
Also, sometimes you may attract HMRC’s attention when your income is dramatically fluctuated or that returns are always late, or that you are claiming excessively high expenses in proportion with your income – all these things can make you high risk in the eyes of HMRC.
HMRC enquiries commonly take one of two forms:
- Limited scope HMRC enquiries – where they ask you to prove one or two figures on your tax returns and if they are satisfied they close their enquiry. If they are dissatisfied, then they often open a full scope enquiry into your affairs.
- Full scope HMRC enquiries – where you must produce all documentation to support your accounts and tax returns. This includes sales invoices, purchase invoices, expense receipts, bank statements, credit card statements, bank paying in books and cheque books. These documents can cover either a full accounting year or more than one year.
