Profit = income minus allowable business expenses
How Class 4 NI works: 6% is charged on profit between £12,570 and £50,270, then 2% on anything above £50,270. It’s separate from Income Tax and doesn’t build State Pension entitlement — that comes from Class 2, which is now credited automatically if profits exceed £7,105.
