Self assessment and NEST contributions

Hi, when completing a self assessment for child benefit when one parent earns over £50k, how are Nest contributions shown. These are taken after tax. Do I simply include the annual employee contributions from pay slips or do I include the tax relief shown in the Nest portal too? Also, the Nest website suggests if you're a higher rate tax payer to claim any additional tax relief.from HMRC? Is this taken into account on Self assessment? Thanks

Hi, can anyone help here? 2023/2023 P60 shows £57k gross income before Nest Pension deductions of circa £3500.

Hi Breedso,
If the pension contributions are taken from your net income after tax calculated then you would enter the grossed up figure in the employers pension scheme box and if you are a higher rate taxpayer you wil receive the additional relief due on your calculation. 
Thank you.
