The UK personal allowance has been frozen at £12,570 since 2021. The higher-rate threshold sits frozen at £50,270. Wages have risen with inflation. Tax thresholds have not moved. Every pay rise therefore pushes more of your income into a higher bracket. The government collects more without ever announcing a rate increase. The Office for Budget Responsibility estimates this freeze will extract over £55 billion from workers by 2030/31. Rachel Reeves extended the freeze to 2031 at Budget 2025.
If thresholds had risen with inflation, the personal allowance would be roughly £16,070 today, not £12,570. The higher-rate threshold would be around £64,270, not £50,270. An income of £35,000 currently produces a tax bill of nearly £4,500. Under indexed thresholds, that figure would be closer to £3,500. Since the freeze began, 5.76 million people are paying higher-rate tax, up 50 percent from 3.83 million in 2019/20. Nearly two million workers crossed the 40 percent bracket without any rate change.
The Law of the Trap: the mechanism is built before you arrive and looks neutral from every angle. Fiscal drag is invisible because it uses your own wage growth against you. The government never said it was raising taxes. It just stopped adjusting the brackets. Most workers feel grateful for a pay rise and do not check whether HMRC took the gain before it reached their bank account. The trap does not announce itself. It simply closes.
The Sovereign One calculates the real after-tax value of any pay rise before celebrating it. Step 6: Internal Intelligence Agency. Run your own numbers. Check what HMRC will collect from that raise before you spend it. If your employer offers salary sacrifice, pension contributions, or cycle-to-work schemes, those reduce taxable income and partially escape the freeze. Know the mechanism.
