A Deep Dive into Each Band
Each bracket has a story. Tap any card to flip it and see what it funds, where it falls short, and how it could be improved.
0%
Personal Allowance
£0 - £12,570
How it works
The first £12,570 you earn is tax-free. Above this, you only pay tax on the portion of income within each band.
20%
Basic Rate
£12,571 - £50,270
How it works
Income between £12,571 and £50,270 is taxed at 20%. This is the rate most UK taxpayers pay on their earnings above the personal allowance.
40%
Higher Rate
£50,271 - £125,140
How it works
Earnings between £50,271 and £125,140 are taxed at 40%. Combined with the personal allowance taper, the effective rate can reach 60% for incomes between £100k and £125k.
45%
Additional Rate
Over £125,140
How it works
All income above £125,140 is taxed at 45%. About 1% of taxpayers reach this band. The pension taper adds further complexity for those earning over £200,000.
The Traps That Cost You Thousands
The headline rates are only half the story. These hidden mechanisms silently reduce your income and benefits.
The 60% Trap - Personal Allowance Taper
£100,000 - £125,140Your personal allowance shrinks by £1 for every £2 earned above £100,000. Combined with 40% income tax and 2% NI, the marginal rate hits 60%. This is one of the highest effective tax rates in the UK and applies entirely within the Higher Rate band.
High Income Child Benefit Charge
£60,000 - £80,000Child Benefit is withdrawn at 1% for every £200 of income over £60,000. By £80,000, it is gone completely. At current rates that means losing up to £1,406/year for a single child, plus the amount for each additional child at £930/year.
The Childcare Cliff Edge
At £100,000This is a cliff edge, not a taper.
If either parent earns over £100,000 Adjusted Net Income, you instantly lose:
- ✖30 hours free childcare per week during term time (worth ~£6,000/year)
- ✖£2,000/year Tax-Free Childcare top-up
One pound over the threshold costs up to £8,000 in lost childcare support - a powerful disincentive to earn more.
Pension Annual Allowance Taper
Over £200,000Your annual pension allowance drops from £60,000 to as low as £10,000 once total income exceeds £200,000. Exceeding the tapered allowance incurs a tax charge at your marginal rate. This particularly affects senior NHS doctors and high-earning public servants.
Winter Fuel Payment - Means Tested
Pension Credit claimants onlyWinter Fuel Payment is now means-tested. Only households claiming Pension Credit or certain other qualifying benefits receive the payment (worth up to £300/year). Make sure to check eligibility on GOV.UK if you or a family member may qualify.

How the System Could Be Better
These proposals come from think tanks, economists, and parliamentary reports. They represent common approaches to fixing the issues outlined above.
Merge NI and Income Tax
National Insurance is essentially a second income tax with different thresholds and rules. Merging them would simplify the system, reduce administration costs, and make the true tax rate transparent. The 2026/27 NI cut to 8% for most earners is a step toward this.
Impact: Simpler system, fewer traps, transparent rates
Index-link Thresholds
Freezing tax thresholds (fiscal drag) is a stealth tax rise. Index-linking the personal allowance, higher rate threshold, and taper start points to CPI or average earnings would stop people being dragged into higher brackets by inflation alone.
Impact: No more stealth tax rises from inflation
Smooth the Childcare Cliff Edge
Losing all childcare support the moment one parent hits £100k is a brutal cliff edge. A phased taper (like the personal allowance taper) from £100k to £150k would remove the disincentive to earn more.
Impact: Removes a major work disincentive for parents
Broaden the 60% Trap Band
The personal allowance taper creates a 60% marginal rate between £100k and £125k. Spreading the taper over a wider band or reducing the taper rate would lower this effective rate and reduce the incentive for tax avoidance.
Impact: Lower effective marginal rate for high earners
Reform Pension Taper Rules
The tapered annual allowance is complex and catches many NHS doctors and senior public servants by surprise. Simplifying the rules or raising the threshold above £200k would allow experienced professionals to stay in work without penalty.
Impact: Keeps senior professionals in the workforce
