Question to the HM Treasury:

To ask Mr Chancellor of the Exchequer, how many demand notices for an overpayment of child tax credit have been sent out in the last financial year.

It is not possible to identify the volume of overpayment demand notices relating specifically to Child Tax Credit.

Tax credit overpayment data relating to Working Tax Credits and Child Tax Credits combined for 2015-16 is available publically and can be found on page 8 of the Child and Working Tax Credits, Finalised Annual Awards, Supplement on Payments National Statistics at; https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/617181/Child_and_Working_Tax_Credits_statistics_finalised_annual_awards__supplement_on_payments_-_2015_to_2016.pdf

The equivalent information for 2016-17 will be published in May/June 2018.
