My hon. Friend rightly points out that an element of NICs is already hypothecated, which is sometimes forgotten by people who are concerned about the hypothecation in the levy. I will take his remarks as a suggestion and reflect on them further. I recognise his expertise in this area, so I am grateful for the intervention.
Serendipitously, I will now address my hon. Friend’s amendment. This amendment asks that HMRC should publish a forecast of the estimated costs of collecting the levy. The published tax information impact note sets out clearly that the operational costs of the levy are being quantified. I have given a preliminary indication, but we will publish the final estimates before the levy comes into effect in April 2022. This amendment is therefore not necessary and I would ask him to consider not pressing it to a vote.
