Underpaid tax for previous years is being paid through a tax code for this yearby a change

.. Can I change my mind and just pay the underpaid tax, it's only about £250. If so how do I do this. I tried to make a payment but it says nothing to pay.

Hi

You can pay this through your personal tax account and once done, your code will be updated. It shows as nil at the moment due to it being coded.

Thank you
