Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many and what proportion of families have been affected by the High Income Child Benefit Charge in each of the last five years; whether he has had discussions with Cabinet colleagues on the potential merits of a higher threshold for household income to determine eligibility for child benefit; and if he will increase the threshold for the High Income Child Benefit Charge in line with inflation.

The Government publishes annual data on individuals who have declared a High Income Child Benefit Charge (HICBC) liability and individuals that have opted out of getting Child Benefit payments, available on GOV.UK:
