Income from employment = Gross or After pension salary-sacrifice?

Hello, please can anyone advice for my personal tax account, for the "Income from employment" section - should this amount be my contractual (gross) salary, or my actual salary post pension contributions via salary sacrifice. For example's sake, lets say I warn gross £100,000 and pay 20% into my pension via salary sacrifice. Should the "Income from employment" part of my account be regarded as "£100,000" or "80,000"?

Is anyone able to advise please?

Hi,
Your gross taxable salary will usually be declared by your employer as the amount after any salary sacrafice has been deducted.
So the 'income from employment' section will usually show your income after salary sacrafice payments have been deducted.
Thank you.
