Hello, Could you provide some additional clarification on how exaclty Class 4 NIC would be calculated after taking into account the Class 1 NIC on employment income? I am in a similar situation as Callum but cannot work out if I am paying the correct amount or if I double paid NIC. In the 23/24 financial year I have been both employed and self-employed simultaneously for parts of the year. Through PAYE, I have been paying Class 1 NIC contribution, and after submitting my self assessment I have also paid Class 4 NIC. In both my employment and self employment I have earned above the Upper Earning Limit / Upper Profit Limit of 50,270. This implies that I have paid both Class 1 and Class 4 at the main rate - 37,700 at 12% through PAYE and 37,700 at 9% for self employment profit Class 4. I am not sure I understand how the NIC are calculated here. I think I may have overpaid NIC as in the self assessment Class 4 calulcations were independent of the employment Class 1 contributions already made, yet I understand these should come on top of the Class 1 NIC already paid. How can I understand if I that calculation is correct or I am entitled to reclaim part of the Class 4 NIC payments made? Many thanks, Cuisi
