What it means
All of this profit is taxed at the basic rate. Each extra £100 you earn costs about £26 in tax and National Insurance, leaving around £74.
Set aside about 15% of every payment (£4,532 over the year). Because the bill is over £1,000, HMRC will usually also ask for payments on account: roughly £2,266 on 31 January and again on 31 July towards next year.
In Scotland the same profit leaves £25,503.13 (£34.93 more), because Scottish Income Tax has its own bands. National Insurance is the same everywhere.
