UK's frozen Personal Allowance is the largest ongoing stealth tax increase in British fiscal history
The UK Personal Allowance has been frozen at £12.570 since 2021 and will remain frozen through 2028. With cumulative wage growth of approximately 20% since 2021, workers earning £12.570 in 2021 now earn approximately £15.000 — with all the additional income above £12.570 taxable at 20%. The OBR estimated in Spring 2026 that the freeze will have brought approximately 3,8 million additional workers into income tax by 2028, raising approximately £25 billion for the government without any headline rate change.

Higher rate threshold frozen creates UK's highest basic-rate proportion of the workforce in modern history
The Higher Rate threshold (£50.270) is also frozen. At 4% annual wage growth, workers who earned £43.000 in 2021 now earn approximately £52.000 — pushed over the higher rate threshold from 20% to 40% marginal rate. The proportion of UK taxpayers paying higher rate income tax has risen from approximately 11% in 2019 to an estimated 16% by 2026 — the highest since records began. This threshold freeze is the UK's largest effective middle-class tax increase in post-war history.

Employer NIC increase from April 2025 has significantly raised UK labour costs
From April 2025, employer NIC rose from 13,8% to 15% and the secondary threshold dropped from £9.100 to £5.000 annually — meaning NIC applies from much lower earnings. This significantly increased employer labour costs, estimated to raise £25 billion annually. For a worker earning £30.000, annual employer NIC cost increased by approximately £600. The measure was highly controversial and led to employer concerns about hiring impact.

ⓘ Personal Allowance tapers from £12.570 to £0 between £100.000 and £125.140 income — creating an effective 60% marginal rate in this band (40% tax + 20% on lost PA). This PA taper is one of the highest marginal rates in the developed world at this income level. Scottish residents pay different rates (Starter 19%, Basic 20%, Intermediate 21%, Higher 42%, Top 47%).

| Band | Earnings Range (£/year) | Rate | Max NIC in Band | Purpose |
|---|---|---|---|---|
| Lower Earnings Limit | £6.396 | 0% | £0 | Qualifying earnings — no NIC but earns state pension entitlement |
| Primary Threshold to UEL | £12.570 – £50.270 | 8% | £3.016 | Main employee NIC |
| Above UEL | Above £50.270 | 2% | Uncapped | Reduced rate — no ceiling |

| £150.000 | €178.500 | £6.433 | €7.655 | 48,5% | 47,0% |
ⓘ Between £100.000 and £125.140, the Personal Allowance withdrawal creates a 60% effective marginal rate — the highest in the UK tax system. Above £125.140 the additional rate of 45% applies, but NIC at 2% means total marginal is 47%. Employer NIC is excluded — if included, total employer cost exceeds 65% of net take-home at median salaries. EUR at £1 = €1,19 (Jan 2026).

| €120.000 / £100.840 | €5.200 | €5.290 | €6.142 | −€90/mo | −€942/mo |
ⓘ UK consistently produces lower net than Netherlands and Ireland at most salary levels. The UK's NIC structure (employee 8% + employer 15%) combined with income tax produces a high total labour cost relative to net pay. Ireland, despite its 52% combined marginal rate, produces significantly higher net at most levels due to the generous standard rate band and tax credits.

🔬 Methodology & Sources
UK Income Tax Calculation
UK PAYE: income tax calculated on income above Personal Allowance (£12.570 — frozen). Three rates: 20% basic, 40% higher, 45% additional. NIC Class 1 employee: 8% on £12.570–£50.270; 2% above. Personal Allowance tapers £1 per £2 between £100.000–£125.140 creating 60% marginal band. Scottish residents: different 6-band structure (19/20/21/42/47%). UK tax year: 6 April–5 April.
Formula
IT = ((min(Gross, £50.270) − £12.570) × 0.20) + (max(0, Gross − £50.270) × 0.40) − PA_taper_adjustment | NIC = min(Gross − £12.570, £50.270 − £12.570) × 0.08 + max(0, Gross − £50.270) × 0.02

❓ Frequently Asked Questions
UK income tax for 2026/27 (England, Wales, NI): 0% on the first £12.570 (Personal Allowance — frozen), 20% on £12.571–£50.270, 40% on £50.271–£125.140, and 45% above £125.140. Employee NIC adds 8% on £12.570–£50.270 and 2% above. Combined effective rate at £50.000 gross is approximately 30%. Personal Allowance tapers to zero between £100.000–£125.140, creating an effective 60% marginal rate in that band.
The £12.570 Personal Allowance has been frozen since 2021 and is legislated to remain frozen through 2028. This is a deliberate fiscal policy to raise additional tax revenue without increasing headline rates. At 4% annual wage growth, the freeze is equivalent to a progressive real tax increase — workers earning more each year pay tax on a growing proportion of their income. The OBR estimates the freeze will raise approximately £25 billion cumulatively by 2028.
Between £100.000 and £125.140, the UK Personal Allowance is withdrawn at £1 per £2 of income above £100.000. This means earning an extra £1 in this band costs £0.40 in higher rate tax PLUS £0.20 lost Personal Allowance (taxed at 40%) = £0.60 effective marginal rate. This 60% effective marginal rate is one of the highest in the developed world at this income level. Pension contributions are an effective way to avoid this trap.
The Netherlands produces higher net monthly salary at most income levels — approximately €200-€350 more at €50.000-€100.000 gross. UK's advantage is a lower base rate (20% vs Netherlands' 36,97% Box 1 first bracket), but the 8% NIC on top erases most of this. At €35.000, Netherlands (€2.250) beats UK (€2.167). At €100.000, Netherlands (€4.960) beats UK (€4.760). Ireland consistently produces the most — it beats both by a significant margin.
Scottish residents pay different rates under the Scottish Rate of Income Tax (SRIT): Starter Rate 19% (£12.571–£15.397), Basic Rate 20% (£15.398–£27.491), Intermediate Rate 21% (£27.492–£43.662), Higher Rate 42% (£43.663–£75.000), Advanced Rate 45% (£75.001–£125.140), Top Rate 48% (above £125.140). NIC remains UK-wide. A Scottish higher-rate taxpayer pays 1-2% more than English equivalent — a significant policy divergence since Scottish devolution of income tax powers.
