R03 · LO1 Income tax — personal allowance tapering

For the tax year 2025/26, the personal allowance for a UK resident aged 45 with adjusted net income of £80,000 is:

A £12,570
B £10,570
C £7,570
D £0

Correct answer: A

The personal allowance of £12,570 is only tapered when adjusted net income exceeds £100,000. The taper reduces the allowance by £1 for every £2 of income above £100,000 — so it is only fully removed when income reaches £125,140. At £80,000, the individual's income is below the £100,000 threshold, so the full personal allowance of £12,570 applies. This is a common exam trap — candidates often confuse the taper threshold with the higher-rate threshold of £50,270.
