Calculating Pension Input Amounts

Good afternoon. I am after some advice on how to calculate Pension Input Amounts for my (defined contribution) SIPP. My SIPP provider has given me two figures for each tax year - total net contributions and total contributions including the tax relief claimed. Can you advise me which of these figures should be used? (I have seen conflicting advice online). I also have a follow up question. I also have a (defined benefit) public service pension, for which I have Pension Input Amount figures. Is my total Pension Input Amount for a given tax year just the sum of the two Pension Input Amounts (occupational pension plus SIPP)? Thank you.

Hi,
We cannot advise you on this as this is financial advise which HMRC are not authorised to give.
Thank you.
