RE: Calculating Net Adjusted Income for Child Benefit High Income Tax ChargeI have a similar query. I will earn £57k in year ending April 23. I have claimed child benefit all year. £57 k will be the figure on my P60. My pension is ‘relief at source’ so I understand this has no bearing on my net adjusted income although I wonder if you could clarify why? If I was to put £7k into a private pension would this make my net adjusted income £5Ok?
