The UK currently applies income tax at 20% on income between £12,570 and £50,270, 40% up to £125,140, and 45% above that for the 2026/27 tax year in England, Wales and Northern Ireland. A single rate for all citizens would replace this progressive structure. Proponents claim flat taxes simplify compliance and reduce incentives for evasion through complex avoidance schemes.
The result was a decisive rejection of a single income-tax rate, with the chamber treating redistribution as more than an administrative nuisance. The highest-respected No case said simply, “If you earn more you pay more”, while another argued that progressive taxation makes those who gain most from the country “pay back at least some of the excess spoils”.
The winning side’s case was not merely instinctive defence of the status quo. Its arguments combined inequality with state capacity: flattening the rates would “shift the entire funding of the state onto low and middle earners”, one voter warned, while another pointed to the contribution made by the highest earners and the risk of leaving ordinary taxpayers to fill the gap.
Yes voters offered a coherent alternative, even if it failed to command the room. Their best-rated argument proposed merging income tax and national insurance to “massively increase tax efficiency”, while other supporters paired a common rate with a larger personal allowance, claiming it would reward ambition, reduce avoidance and make the system easier to administer; one even proposed taxing benefits, a suggestion No voters answered by stressing that benefits are support, not spare income.
The disagreement was therefore less about whether the tax system could be simpler than about where simplicity should begin. Yes voices attacked loopholes, welfare spending and public-sector waste, with one saying the aim should be “baking a bigger one”; No voters countered that the apparently unfair jump between bands is often misunderstood, and that the more urgent case for simplification lies elsewhere, including corporation tax.
The chamber did not reject simplicity; it rejected simplicity purchased by flattening the burden. Here, “fair” meant proportion rather than sameness.
“A flat tax merging income tax and national insurance, with a substantial personal allowance that doesn’t taper off for high earners would massively increase tax efficiency. We would become much more prosperous as a country.”

Taking 25% off a nurse who is already struggling with heating bills hurts a hell of a lot more than taking 25% off a private equity boss buying a fourth sports car. It destroys progressive taxation, shifts the entire funding of the state onto low and middle earners, and blows a black hole in the NHS budget
A flat tax merging income tax and national insurance, with a substantial personal allowance that doesn’t taper off for high earners would massively increase tax efficiency. We would become much more prosperous as a country.
But lower paid should only pay tax when they earn £20 t0 25,000
Simplifying the tax system is vital. But let’s start by taxing benefits. I see no reason why the laziest amongst us should be immune from being taxed like those of us who get up every day to toil.
A flat tax or 25-30% with a tax free element of £20-25K. All allowances repealed, no one on benefits can earn more than working person 2 Child cap reinstated. HMRC cut by 2/3rds. Issue is tax system is used to reorder society & punish citizens hence why the left rabbit on about fairness but never define it. ‘Fairness’ in their mind is whoever they decide to tax should shut up & pay. We should be aiming for society where ambition is paramount & rewards achievable.
What is being suggested here, that the lowest rate should be raised? We have a progressive rate of tax for a reason. If the overall tax take is insufficient to balance expenditure then there is little option but to raise the entire regime. If you can afford the latest iPhone then you can certainly afford more tax.
Same rate but starting at different personal allowances.
Yes - it will mean people can earn more without fear of being penalised for being ambitious or entrepreneurial and therefore will incentivise growth, while simultaneously discouraging the government overspend on welfare. It’s also literally the fairest way of taxing - everyone pays the same, no matter what.
No, absolutely not how can people who are on less money, pay the same who are on more money, its simply economically disadvantages the poor.
