If I successfully appeal a late payment penalty, will the late payment interest also be refunded (i.e. the interest charged for late payment of the self assessment balancing payment, not the interest on the penalty)?
I only recently realised that I had to complete a self-assessment (I wasn't aware of the high income benefit charge for Child Benefit and I have always paid tax through PAYE). I've now submitted the overdue self assessments and paid the overdue tax bill in 2 payments at the beginning of this month.
As I have only recently made payment, the payments didn't appear on my April tax statement. However, my tax code has now changed to take child benefit payments into account. My statement says that the balancing payment for 2022/23 will be included in my PAYE code for 2024/25, so what are the deductions for this year's PAYE for?
