What it means
Part of this profit is in the higher-rate band (40% Income Tax on profit above £50,270, with National Insurance dropping to 2%). Each extra £100 earned costs about £42. Pension contributions and allowable expenses reduce the bill at the higher rate.
Set aside about 21% of every payment (£11,789 over the year). Because the bill is over £1,000, HMRC will usually also ask for payments on account: roughly £5,894 on 31 January and again on 31 July towards next year.
In Scotland the same profit leaves £41,561.35 (£1,650.05 less), because Scottish Income Tax has its own bands. National Insurance is the same everywhere.
