A £100,000 salary is a landmark figure — it sits at exactly the point where the personal allowance taper begins. At precisely £100,000 your full £12,570 personal allowance still applies, because the taper only reduces the allowance on adjusted net income strictly above this level. Your take-home of £68,557 reflects the standard higher rate calculation with no taper reduction.

After income tax and National Insurance you take home £68,557 per year — that is £5,713 per month. Your overall effective deduction rate is around 31%, but this figure understates the risk: earning even £1 above £100,000 triggers the personal allowance taper, pushing the effective marginal rate on that additional income to 60%.

The personal allowance taper is widely regarded as the most punishing aspect of the UK tax system for higher earners. Between £100,000 and £125,140 you face a 60% effective marginal rate — higher than the additional rate that applies above £125,140. This is not a mistake in the system; it is an intentional design. Salary sacrifice pension contributions are the standard and most effective response: they reduce your adjusted net income before the taper calculation, protecting your personal allowance and keeping your marginal rate at 42%. Use the calculator above to see how a pension contribution changes your take-home at this critical level.

Frequently asked questions

How much is £100,000 a year after tax?

On a £100,000 salary in England and Wales for 2026/27, your take-home pay is £68,557 per year — that is £5,713 per month or £1,318 per week. At exactly £100,000 the full £12,570 personal allowance still applies, as the taper only reduces the allowance on income strictly above £100,000. This assumes the standard 1257L tax code, no pension contributions and no student loan.

What is the personal allowance taper and how does it work at £100,000?

The personal allowance taper is one of the most significant and poorly understood features of the UK tax system. HMRC reduces the standard £12,570 personal allowance by £1 for every £2 of adjusted net income above £100,000. This means that between £100,000 and £125,140, every extra £2 earned not only attracts 40% income tax on that £2 — it also removes £1 of personal allowance, which was previously sheltering £1 of income from tax. The combined effect is an effective marginal rate of 60% on earnings in that range. At exactly £100,000 the taper has not yet started, but earning even £1 more triggers it.

Why is the marginal tax rate 60% between £100,000 and £125,140?

Here is the mechanics: for every £2 earned above £100,000, you pay 40% income tax on the £2 (80p), and you also lose £1 of personal allowance. That lost £1 of allowance was previously tax-free but now becomes taxable at 40%, adding another 40p of tax. So on £2 of extra earnings you pay £1.20 in tax — a 60% effective rate. This continues until your personal allowance is fully withdrawn at £125,140. Salary sacrifice pension contributions are the standard solution: contributions made before the taper kicks in keep your adjusted net income below £100,000 and your full personal allowance intact.

How much income tax and NI do I pay on £100,000?

At exactly £100,000 you pay 20% on the first £37,700 of taxable income above the £12,570 personal allowance (£7,540), then 40% on the £49,730 above the higher rate threshold of £50,270 (£19,892). Total income tax is £27,432 per year. National Insurance is £3,016 on the band between £12,570 and £50,270 at 8%, plus £995 on the £49,730 above the upper earnings limit at 2%, totalling £4,011 per year.

How can I avoid the 60% marginal rate trap?

The most widely used strategy is salary sacrifice pension contributions. If your employer offers salary sacrifice, contributing enough to bring your adjusted net income below £100,000 preserves the full £12,570 personal allowance. For example, if you expect a £10,000 bonus that would take your income to £110,000, contributing £10,000 to your pension via salary sacrifice keeps you at £100,000, saves £4,200 in combined tax and NI on the contribution itself, and protects £5,000 of personal allowance from being withdrawn — avoiding a further £2,000 in tax on the restored allowance. Total saving: over £6,000.
