Right. Let’s talk about something that affects every single person earning money in Britain – UK tax brackets. Not exactly riveting dinner party chat, but it matters when you’re wondering why your salary increase somehow disappeared before it reached your bank account.
So what are the UK tax brackets? Basically, they’re the income ranges that determine how much of your wages get nicked by HMRC. Different chunks of your salary get taxed at different rates. Simple enough in theory. Bit messier in practice.
The Numbers That Actually Matter
For the 2025/26 tax year starting this past April, here’s where we stand. You get to earn your first £12,570 completely tax-free. That’s your personal tax allowance 2025/26. Anything beyond that? Different story.
- Between £12,571 and £50,270, you’ll pay 20% on every pound. That’s the basic rate. Most people live here. These are often called UK tax slabs, though officially they’re called bands or brackets.
- Then from £50,271 to £125,140, you’re coughing up 40% on that slice. Higher rate.
- And if you’re lucky enough to earn money above £125,140? You’re paying 45% on everything beyond that threshold.
But here’s where it gets properly annoying. If you earn over £100,000, your personal allowance starts vanishing. For every £2 you earn above a hundred grand, you lose £1 of that tax-free allowance. By the time you hit £125,140, your allowance is completely gone. Zero.
Think about that for a second. You’re earning between £100,000 and £125,140, losing your allowance, and effectively paying 60% tax on that slice. Not officially called a tax bracket, but that’s what’s happening in your payslip.
Scotland’s got its own system with six different rates rather than three, but we’ll stick to England, Wales, and Northern Ireland for now.
Why Your Take-Home Pay Feels Worse Than Last Year
Here’s the kicker. Those thresholds? They’ve been frozen since April 2021. Frozen. Solid. Not moving until at least April 2028, possibly longer.
Labour’s recent budget extended the freeze until 2031.
When inflation’s running hot and wages are climbing to keep up, frozen thresholds mean you’re getting dragged into higher tax brackets without actually being richer. It’s called fiscal drag. Sneaky, innit?
Let’s say you were earning £30,000 back in 2021. After your personal allowance, you paid 20% tax on £17,430. If your wages have risen with inflation to roughly £35,000 now, you’re paying 20% on £22,430. That’s five grand more of your income getting taxed. Same purchasing power, higher tax bill.
Analysis from the House of Commons Library reckons roughly 1.9 million more people will be dragged into paying higher rates of tax by the end of the decade because of these freezes. That’s not raising tax rates. That’s letting inflation do the dirty work. Costs the government nothing to announce. Raises billions in revenue. Brilliant if you’re the Chancellor. Less brilliant if you’re everyone else.

What You Can Actually Do With This Information
Most people don’t need a UK tax calculator to work out they’re paying more tax. You just look at your payslip and wonder where it all went. But understanding the brackets helps you make smarter decisions.
If you’re hovering near £100,000, for instance, that 60% effective rate between £100k and £125,140 is worth avoiding. Pension contributions can pull your taxable income back down below that threshold. The same with charitable donations through Gift Aid or salary sacrifice schemes.
Below £12,570? You’re not paying income tax at all, though you might still be paying National Insurance if you’re earning above £242 a week. That’s another thing people forget. Income tax and National Insurance are separate. Both come out of your wages. Both hurt.
So how much tax should I pay? Well, it depends entirely on your total income and which bracket you fall into. National Insurance is currently 8% on earnings between roughly £12,570 and £50,270 a year, then drops to just 2% on anything above that. So your marginal rate in the basic tax band is actually 28% when you combine the two. Not quite as simple as just “20% tax.”
Will Labour Increase Personal Tax Allowance? Not Likely
There is a petition with more than 250,000 signatures calling for the government to raise the personal allowance to £20,000. Would be lovely, wouldn’t it? But the government has already said no. Treasury estimates are that raising the allowance to £20,000 would cost between £50 and £65 billion. That’s roughly the entire defence budget.
The minister rejected the idea pretty quickly in May, saying there are “no such plans.” Instead, they pointed to the national living wage going up and the state pension increasing. Which is nice and all, but doesn’t change the fact that frozen thresholds mean more people paying more tax.
Will labour increase personal tax allowance anytime soon? The answer appears to be a firm “no.” They’ve promised not to raise the rates of income tax itself. But freezing the thresholds? That’s fair game. Technically they’re keeping their manifesto promise. The rates aren’t changing. Just the number of people paying them.

The Stuff That Doesn’t Get Mentioned Enough In UK Tax Brackets
Everyone focuses on income tax rates. But there’s more to it. Dividend income gets taxed differently. You get a £500 dividend allowance for 2025/26, then pay tax based on your income bracket. Savings interest has a personal savings allowance too, which varies depending on whether you’re a basic or higher-rate taxpayer.
Capital gains tax is another beast entirely. You can make gains of up to £3,000 tax-free this year, then pay either 18% or 24% depending on your income tax band. That’s for most assets. Property has different rates.
And if you’re running a limited company? You’ll be dealing with UK corporation tax rates, which currently sit at 19% for profits up to £50,000 and 25% for profits above £250,000. There’s a tapered rate between those thresholds. Different system entirely from personal income tax.
The point is, the tax system’s complicated enough that most people don’t realise how much they’re actually paying overall. It’s not just about the UK income tax rates 2025/26. It’s National Insurance, council tax, VAT on everything you buy, fuel duty, alcohol duty, and whatever else the Treasury’s dreamed up this year.
What Happens Next
The thresholds staying frozen until 2031 means we’ve got years of fiscal drag ahead. Unless inflation miraculously disappears or wages stop rising (neither of which seems likely), more people will keep getting pulled into higher brackets.
The government’s hoping to raise roughly £8 billion by 2029/30 just from these frozen thresholds. That’s on top of the £25.7 billion they’re pulling in from raising employer National Insurance contributions. Businesses are already saying they’re not hiring because of higher payroll taxes. Some aren’t replacing workers who leave.
It’s a mess, frankly. But it’s the mess we’ve got.

The Bottom Line
So, what are the UK tax slabs? They’re tax-free up to £12,570, then 20% up to £50,270, then 40% up to £125,140 and 45% beyond that. Scotland’s different. Northern Ireland and Wales follow England’s system.
But the brackets themselves are only part of the story. The freezes matter more than the rates right now. Your taxes are going up even though the percentages aren’t changing. That’s modern Britain for you.
If you want to check exactly what you’ll pay on your specific income, there are plenty of calculators online. HMRC has one. They’re pretty accurate as long as you’re honest about your income and any other complications like student loans or pension contributions.
Look, nobody enjoys paying tax. But understanding how it works at least means you’re not getting blindsided every time you check your payslip. Small mercies and all that.
