The standard Personal Allowance for 2026/27 is £12,570, which is tax-free. For salaries above £100,000, the allowance tapers by £1 for every £2 earned, disappearing entirely at £125,140. This does not affect the median salary shown here.

At a median £600/day, contract work grosses about £132,000 a year over 220 billable days, 39% more than the £95,000 permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts. Whether a contract falls inside or outside IR35 also changes how much of it you keep. Contract and permanent benchmarks come from separate samples, so treat the gap as a guide.
