Risk Intelligence Assessment Teams (RIATs) - Investigation triggers

A while ago now HMRC moved responsibility for deciding which taxpayers would have their tax returns subjected to an enquiry away from local inspectors to Risk Intelligence Assessment Teams (RIATs).

RIATs have information and statistics available on a country-wide basis. This allows RIATs to spot trends, compare income, expenses, profit ratios, etc. with similar businesses on a nationwide basis. 

RIATs do not, for obvious reasons, publicise all of the possible triggers, but here are some of them:

  • Recurring late submission of accounts/tax returns overdue in recent years
  • Significant fluctuation in income or expenses
  • Significant errors including no adjustments for private use element
  • Low income compared with outgoings.
