The International Monetary Fund does not normally do hyperbole. It is a bureaucratic institution that produces measured technical assessments. So when its officials in Washington describe Britain as having reached "peak taxation", that is a warning light flashing red on the dashboard of the British economy.

The numbers behind that judgment are stark. Since Labour took office in July 2024, the government has imposed roughly £75 billion of new taxes on businesses and households. The UK now has the largest tax increase of any G7 country in this parliament — France comes second, and at some distance. The tax burden is forecast to rise by 4.5 percentage points of national income between 2024 and 2031, pushing it above 40% of GDP. That is the highest level since the Second World War.

Higher Tax Has Not Bought Better Services

You might be willing to accept this if it bought you something. It hasn't. The NHS waiting list is still north of 7 million. Diagnostic backlogs are at record highs. Cancer waiting times are missed. The 18-week pledge has been quietly abandoned. The police can't get to your house if your car is broken into. Class sizes are up. School budgets are being raided to pay the council's social-care commitments.

So where did the £75 billion go? It went on welfare, on asylum hotels, on debt interest, on a public-sector pay round that wasn't tied to productivity, on net-zero subsidies, and on a quango state that grew while frontline services shrank. Labour didn't tax-and-spend on the things voters actually wanted. They taxed-and-spent on the things their party machine wanted.

The Stealth Tax Is The Worst Of All

The most damaging part of the £75 billion isn't the headline rises. It's the frozen thresholds — fiscal drag, in technical language, but in plain English: a pay rise that used to keep up with the cost of living now drags you into a higher tax bracket. Year after year. The Treasury collects more, and you keep less. It is the perfect Whitehall tax: invisible at the point of collection, ferocious in cumulative effect.

The OBR has confirmed thresholds will now stay frozen all the way to 2031. That is seven full tax years of stealth squeeze. A new graduate today is staring at a working life in which every pay rise will be partially confiscated before it reaches their bank account.

On top of that, the dividend tax has risen — from 8.75% to 10.75% at the basic rate, and from 33.75% to 35.75% at the higher rate. Inheritance tax now bites pensioners and farmers as well as the genuinely wealthy. AIM share relief has been gutted. Business Asset Disposal Relief has been hiked. Salary sacrifice has been capped. The full menu of small-print raids is now active.

The OECD Has Said The Same Thing

It isn't just the IMF. The OECD, only last month, urged Chancellor Rachel Reeves to overhaul the UK tax system. The verdict was unsparing. It called the system "complex" and "distorting". It said it actively discouraged work. It described our sales tax reliefs as "inefficient and regressive". It pointed out that the property tax valuations Britain still uses date from a generation ago. Almost every problem the OECD identified is a problem of Labour's own making, made worse by Labour's own choices.

You Cannot Tax Your Way to Growth

The biggest lie Labour told the country at the last election was that you could squeeze the rich, the business owners, the savers, the farmers, the landlords, and the pension funds — all at once — and have nothing bad happen to growth. Two years on, the IMF has downgraded UK growth for 2026 to 0.8%. The biggest downgrade of any G7 country.

That is what happens when you turn the dial past the point where extra tax brings in extra revenue. People leave. Businesses don't expand. Pensioners give up. Savers move money offshore. The base shrinks. Eventually you end up taxing more, and collecting less. That is the doom loop Britain is now in.

What Reform UK Would Do

The answer is not complicated. Reform UK would take Britain off the doom loop and back onto a growth path. Lift the personal allowance to £20,000. Take low-paid workers out of income tax altogether. Stop fiscal drag by linking thresholds to inflation. Cut the absurd corporate-compliance burden choking small business. Honour the pensioner triple lock. Reverse the inheritance-tax raid on family farms. Abolish the Department for Energy Security and Net Zero and the bill levies it spawned.

The IMF has said it bluntly. Britain has hit peak taxation. There is no "another tax rise" left in this country. The next government can either accept that and start cutting — or it can keep raiding people's pay packets and pension pots and watch growth collapse. Labour has chosen the second path. Reform UK will not.
