Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, what the average time taken was to complete an investigation into the alleged presence of an unreported adult in the household of a tax credit claimant in the past 12 months; and if he will make a statement.

Between 1 September 2015 and 31 August 2016, the average time taken to complete a tax credit undeclared partner investigation by HM Revenue and Customs (HMRC) from the point at which they first write to the customer to closure, was 51.27 days. During the same period, Concentrix acting on behalf of HMRC took an average of 65.34 days.

Where an alleged presence of an unreported adult occurs, claimants are given 30 days to contact HMRC or provide the relevant information. If after 30 days HMRC has had no contact, tax credit payments are either suspended or reduced. HMRC then gives the claimant a further 30 days to contact HMRC before making a decision on the household composition and tax credits award using all the available information.
