Introduction
Ever wondered who’s really keeping the lights on at the Treasury? Turns out, it’s a pretty exclusive club. The top 1% of UK taxpayers coughed up a staggering 33% of all income tax and capital gains tax in 2023-24—that’s £93.8bn from just 500,000 people. While Rachel Reeves eyes the wealthy for next month’s Budget, this eye-watering concentration reveals just how much Britain’s public purse relies on its richest residents. Let’s break down what this means for your wallet and the country’s finances.
The Numbers Behind the Tax Burden
HMRC’s data paints a stark picture. The top 500,000 earners contributed £93.8bn last year—roughly a third of total receipts. Zoom in further, and the top 100,000 alone paid £54.9bn, covering a fifth of everything collected.
This isn’t just trivia for dinner parties. It exposes a fundamental vulnerability: when a tiny slice of the population shoulders such a massive share, any economic wobble affecting high earners sends shockwaves through public finances.
The Treasury defends this as “progressive taxation”—those earning more pay more. Fair enough. But it also means the government’s increasingly betting on the same horses to fund schools, hospitals, and roads.
Rachel Reeves Targets the “Broadest Shoulders”
The Chancellor’s made no secret of her plans. Next month’s Budget will lean on those with the “broadest shoulders” to pay their “fair share.” Translation? Expect more tax grabs aimed at wealth.
However… if you’re already leaning heavily on the top 1%, how much harder can you squeeze before they start looking for the exit? History suggests there’s a tipping point where aggressive taxation becomes counterproductive.
Reeves is walking a tightrope between raising revenue and spooking the very taxpayers she depends on.
Fiscal Drag: The Silent Tax Rise
While politicians debate headline rates, there’s a sneakier force at play—fiscal drag. By freezing tax thresholds, the Treasury’s been quietly dragging more earners into higher bands as wages rise.
Last month, HMRC collected £32bn more than the previous year. Income tax and national insurance hit £235.3bn, but as Quilter’s Rachael Griffin notes, this figure’s “artificially inflated” by frozen thresholds.
“This doesn’t point to a roaring economy but a sign of a Treasury increasingly reliant on extracting more from the same taxpayers,” Griffin explains.
Reeves positioned unfreezing thresholds as a signature move in her first Budget. Now? She might be tempted to delay, quietly preserving billions in extra revenue despite the political headache.
A £30bn Shortfall Looms
The public purse isn’t just tight—it’s precarious. The upcoming Office for Budget Responsibility forecast predicts a £30bn gap between day-to-day spending and tax receipts in the final forecast year.
Reeves’ fiscal rules demand these balance out. Meeting that target means either cutting spending (unpopular) or raising taxes (also unpopular). Pick your poison.
Capital Economics’ Ruth Gregory highlights another wrinkle: government borrowing in September exceeded OBR forecasts despite a £40bn tax raid last Budget, including employer national insurance hikes.
“This is surprising given the economy hasn’t been terribly weak,” Gregory says. “Perhaps compositional effects are at play, such as the rise in food inflation prompting more spending on zero-VAT rated food items.”
The real test? What the OBR forecasts for 2029-30, when Reeves’ fiscal mandate truly bites.
What This Means for You
If you’re not in the top 1%, you might think this doesn’t affect you. Wrong. When the government relies so heavily on high earners, policy decisions start revolving around keeping them happy (or at least present).
Plus, fiscal drag affects everyone. As inflation pushes wages up, more middle earners get dragged into higher tax bands—paying more without feeling richer.
The broader lesson? UK public finances are walking a tightrope, and we’re all along for the ride.
Conclusion
The top 1% paying a third of UK tax revenue isn’t just a fun stat—it’s a warning sign. Britain’s fiscal health depends on a surprisingly small group, and with a £30bn shortfall looming, the pressure’s mounting. Whether Reeves can balance the books without breaking the economy remains to be seen. One thing’s certain: watch next month’s Budget closely.

FAQ
Q1 How much tax do the top 1% of UK earners pay?
A: The top 1% (around 500,000 taxpayers) paid £93.8bn in income tax and capital gains tax in 2023-24, representing 33% of total receipts. The top 100,000 alone contributed £54.9bn.
Q2: What is fiscal drag and how does it affect me?
A: Fiscal drag happens when tax thresholds are frozen while wages rise due to inflation. You get pushed into higher tax bands without actually becoming wealthier—meaning you pay more tax on paper gains.
Q3: Why does the government rely so heavily on high earners?
A: The UK operates a progressive tax system where higher earners pay disproportionately more. While this funds public services, it also creates vulnerability—if wealthy taxpayers leave or earn less, revenue plummets.
Q4; What is Rachel Reeves planning in the upcoming Budget?
A: Reeves has signaled she’ll target those with the “broadest shoulders” to pay more tax, likely through wealth-focused measures. However, specifics won’t be clear until Budget day.
Q5: Could the UK face a fiscal crisis?
A: The OBR forecasts a £30bn shortfall between spending and tax receipts in the final forecast year. While not an immediate crisis, it puts serious pressure on the Chancellor to either cut spending or raise taxes significantly.
