What it means
Between £100,000 and £125,140 the Personal Allowance is withdrawn, £1 for every £2 over £100,000. That makes the effective rate on this slice about 62% including National Insurance. Personal pension contributions can bring profit back under £100,000 and restore the allowance.
Set aside about 37% of every payment (£46,189 over the year). Because the bill is over £1,000, HMRC will usually also ask for payments on account: roughly £23,094 on 31 January and again on 31 July towards next year.
In Scotland the same profit leaves £73,636.35 (£5,175.05 less), because Scottish Income Tax has its own bands. National Insurance is the same everywhere.
