A client of mine is a higher rate tax payer and makes the minimum auto enrolment pension contributions from their net pay (i.e. after tax) as the pension scheme is set up as Releif at source. This means that the penison scheme will claim back the 20% basic tax relif, but as a higher rate tax payer he is entitled to another 20% tax releif.
I understand that this has to be claimed through his tax return. The problem is that I cannot work out which box on his self assessment I should be adding this information to. Can anyone help?
