Why the Permanent Equivalent Is Lower
A contractor on £1200/day earns £264,000/year gross. But a permanent employee on that salary also gets employer pension (3-10%), 25-28 days holiday (paid), sick pay, employer NI contributions (15%), and training, equipment, and other benefits. These benefits are worth roughly 25-35% of salary, so the equivalent permanent salary is £198,000.
Take Home at £264,000 (2025/26)
On PAYE or inside IR35, £264,000 loses £105,003 to income tax and £7,291 to National Insurance at 2025/26 rates (thresholds frozen to 2028), leaving £151,706 — £12,642 a month, or 57.5% of gross. The marginal rate on every extra pound is 47% (45% additional rate plus 2% NI), and the personal allowance is long gone: it tapers away between £100,000 and £125,140. By contrast, the £198,000 permanent equivalent nets £9,727/month — £2,915 less per month, which is precisely the premium you are being paid for carrying contractor risk. For scale, £264,000 is roughly 7.5 times the UK median full-time salary of about £35,000.
Pension Contributions Change the Maths
Pension contributions are the single most effective tax lever at this income, with relief at your 47% marginal rate. At £264,000 your adjusted income sits above HMRC's £260,000 taper threshold, so per gov.uk guidance your annual allowance is cut by £1 for every £2 above the line — roughly £58,000 here rather than the standard £60,000 (assuming no other income or pension accrual). Contributions beyond the tapered allowance trigger an annual allowance charge, though carry-forward of unused allowance from the previous three tax years can extend the headroom.
