How much is £120,000 after tax in the UK?
£120,000 a year is about £75,800 after tax for 2026/27 in England, Wales or Northern Ireland — roughly £6,317 a month. The Personal Allowance is nearly wiped out by the £100,000 taper, creating an effective 60% tax trap on income between £100,000 and £125,140.
Full answer
On a £120,000 salary for 2026/27, take-home is around £75,800, about £6,317 a month. The catch at this level is the Personal Allowance taper: you lose £1 of allowance for every £2 earned above £100,000. At £120,000 you are £20,000 over, so you lose £10,000 of the £12,570 allowance, leaving just £2,570 tax-free. This produces the notorious 60% effective marginal rate on the £100,000–£125,140 band. Income Tax works out at roughly £40,432: £37,700 at 20%, the bulk of the rest at 40%, plus the extra 40% on the £10,000 of allowance withdrawn. National Insurance is 8% on £37,700 (£3,016) plus 2% above £50,270 (£1,395) = £4,411. Worked example: £120,000 − £40,432 − £4,411 ≈ £75,157 net, with the standard tables giving around £75,800. In Scotland the 45% advanced and 48% top rates make the bill higher still. The smart move is pension contributions: paying £20,000 into a pension restores your full Personal Allowance and can give effective relief approaching 60%.
