Full answer

At £105,000 in 2026/27, you are £5,000 above the £100,000 Personal Allowance taper threshold, so your Personal Allowance is reduced by £1 for every £2 of income above £100,000 -- a £2,500 reduction, leaving a Personal Allowance of £10,070 instead of the standard £12,570. Taxable income is therefore £94,930: the first £37,700 is taxed at 20% (£7,540) and the remaining £57,230 at 40% (£22,892), giving total Income Tax of £30,432. National Insurance is 8% up to the £50,270 Upper Earnings Limit (£3,016) plus 2% on the £54,730 above it (£1,094.60), totalling £4,110.60. Combined deductions of £34,542.60 leave £70,457.40 take-home a year, around £5,871.45 a month or £1,354.95 a week. The £5,000 of income between £100,000 and £105,000 is taxed particularly harshly: each pound in this band is taxed at 40% Income Tax, loses 50p of Personal Allowance (which itself becomes taxable at 40%, adding a further 20p), and also incurs 2% National Insurance -- an effective marginal rate of around 62% on this slice of income. In Scotland, the equivalent calculation produces Income Tax of approximately £34,107, reflecting both the taper and the higher Scottish advanced and top rates. Many people at this income level make additional pension contributions specifically to bring their adjusted net income back to £100,000 or below, effectively reclaiming the lost Personal Allowance.
