How UK income tax works in 2026/27
The UK tax year runs 6 April 2026 to 5 April 2027. For England, Wales and Northern Ireland, HMRC charges income tax on earnings above the personal allowance of £12,570, which has been frozen since 2021 and stays frozen until at least 2031. The standard tax code is 1257L.
- Basic rate, 20% — income from £12,571 to £50,270.
- Higher rate, 40% — income from £50,271 to £125,140.
- Additional rate, 45% — income above £125,140.
The allowance itself shrinks above £100,000: you lose £1 of allowance for every £2 earned over £100,000, so it is gone entirely at £125,140. In that band the effective marginal rate is 60% — a trap many new arrivals discover only on their first payslip.
National Insurance: the second deduction
Class 1 employee National Insurance in 2026/27 is 0% up to £12,570, 8% from £12,570 to £50,270 and 2% above £50,270. Your employer pays a separate 15% above £5,000 a year, which never appears on your payslip but is part of the real cost of hiring you. National Insurance is what buys your entitlement to the state pension and most state benefits — after 10 qualifying years you get a partial pension, after 35 years the full amount.
Worked example: £45,000 gross salary
Personal allowance £12,570 leaves £32,430 taxable, all in the basic-rate band: income tax £6,486. National Insurance at 8% on the same £32,430 is £2,594.40. Take-home is £35,919.60 a year, or about £2,993.30 a month — an effective rate of 20.2%. At £60,000 the same model gives £45,357.40 a year (£3,779.78 a month); at £100,000 it gives £68,557.40 (£5,713.12 a month).
What this calculator does not include
Pension contributions (auto-enrolment is typically 5% of qualifying earnings, often salary-sacrificed), student-loan repayments (Plan 2: 9% above £28,470; Plan 5: 9% above £25,000), the Scottish income-tax bands, marriage allowance, salary-sacrifice schemes, and the High Income Child Benefit Charge. If any of those apply, your real take-home will differ — usually lower.
London vs the rest: what £45,000 buys
A £2,993 monthly take-home stretches very differently by city. In London, a one-bedroom flat averages around £2,000 a month in rent in 2026, so housing alone can take two-thirds of this salary. In Manchester, Birmingham or Leeds the same flat is roughly £1,000–£1,300. Many employers pay a London weighting of £3,000–£6,000 a year on top of the base salary — always ask whether the figure in your offer includes it.
Our verdict: On a £45,000 gross salary this model estimates about £2,993 per month take-home. Negotiate the gross with the bands above in mind: every £1,000 of extra salary between £50,270 and £125,140 is worth only about £580 a month after tax and National Insurance — but pension salary sacrifice can push part of it back into your pocket.
