DATA BRIEF 012 · CONTEXT

The Data Context

The UK income tax system concentrates liability sharply at the top — the top 1% of taxpayers pay 27.2% of all income tax, while the bottom 50% pay 9.9%. That ratio has held above 2:1 for over two decades. At the same time, the overall tax burden is rising toward a post-war high driven not by headline rate changes but by frozen thresholds pulling millions into higher bands. Neither the "soak the rich" narrative nor the "Britain is overtaxed" claim survives contact with the data.

Who Pays Income Tax?

In 2023–24, the top 1% of income taxpayers — around 367,000 people — were liable for 27.2% of all income tax. The bottom 50%, some 18.7 million taxpayers, accounted for 9.9%. The top 1% contributes 2.7 times more than the entire bottom half combined, a ratio that has persisted for over two decades and peaked at 3.3:1 in 2021–22 before easing slightly in the most recent data.

A Post-War High

The OBR forecasts the UK tax burden will reach 38.5% of GDP by 2030–31, exceeding the previous post-war record of 37.2% set in 1948–49. The rise is not driven by headline tax rate increases but by frozen thresholds, employer National Insurance changes, and corporation tax — a structural shift rather than an explicit political choice.

The Stealth Tax

There were 4.43 million higher-rate (40%) taxpayers in 2021–22. By 2026–27 that figure is projected to reach 7.7 million — an increase of 3.3 million with no change to the 40% rate itself. This is fiscal drag: the personal allowance and higher-rate threshold have been frozen since April 2021 while wages have risen, pushing millions into a band designed for higher earners.

Progressive or Regressive?

Income tax is clearly progressive — the top quintile pays 22.3% of gross income in income tax, the bottom quintile pays 7.1%. Council tax runs in the opposite direction: the poorest tenth pay around 8% of income in council tax, the richest 40% pay 2–3%. The system as a whole is progressive, but council tax is the most unambiguously regressive major tax in the UK.

Benefits Do the Heavy Lifting

The Gini coefficient — a measure of income inequality — stands at 47.6 before any government intervention. Cash benefits reduce it to 37.3, a fall of 10.3 points. Direct taxes reduce it a further 4.4 points to 32.9. Cash benefits account for the larger share of the reduction: they reduced the Gini by 10.3 points, against 4.4 points from direct taxes.

Mid-Table, Not High-Tax

The UK's tax-to-GDP ratio was 35.3% in 2023, ranking 18th of 38 OECD countries — slightly above the OECD average of 33.9% but well below France (43.8%), Denmark (43.4%), and the EU14 western European average of around 41%. Even the forecast 38.5% by 2030–31 would leave the UK below the current European average.

Read Before You Record

The headline numbers are robust, but their definition and denominator matter. Keep these three qualifications with any retelling of the brief.

Three important caveats
  1. All income tax distribution figures cover taxpayers only — around 43% of UK adults paid no income tax (IFS estimate, 2014–15). The population base matters when making comparisons.
  2. There are two measures of the tax burden in common use: National Accounts taxes (~38.5% by 2031) and public sector current receipts (~42.7%). Both show the same trend. Always specify which you are citing.
  3. The VAT regressivity question is a genuine methodological dispute between ONS (regressive against income) and IFS (neutral against expenditure). Neither is simply wrong. Present both framings.
