(Another) potentially dumb question about P11D, payrolled benefits, and tax returns

Westfalia79

I am a UK tax payer. I completed my return for 2023 and have £2,500 tax to pay. I have entered all the income details from my P60 plus the P11D benefits that total about £2,250. I pay 10% of earnings into my pension which, because it is made by salary sacrifice, I understand that I do not declare it as a voluntary contribution. And yet I still have a sizeable tax bill to pay that is more than P11D benefits. Why?

Have you entered the tax paid from the P60?

Yes. That went into the relevant boxes in the employment section.

You are going to have to provide us with the tax code on your P60. Are you a higher rate taxpayer in receipt of child benefit? £2250 is a very large underpayment for one whose income is solely under PAYE.

Thank goodness someone else thinks it is strange, too! I am a higher rate taxpayer, but not in receipt of tax benefit. My tax code is 1544LM1.

Sorry, that should have read "not in receipt of child benefit".

The personal allowance is 12570. For some reason you have received in excess of that. Perhaps you could provide details of your tax codes throughout 2022/23?
