Full answer

For a £42,000 salary in England, Wales or Northern Ireland during 2026/27, the Personal Allowance covers the first £12,570 at 0%. The remaining £29,430 is taxed at the 20% basic rate, giving Income Tax of about £5,886. National Insurance is charged at 8% on earnings between £12,570 and £42,000, which is 8% of £29,430, or about £2,354. Combined deductions are around £8,240, leaving take-home of roughly £33,760 a year, or about £2,813 a month. At £42,000 you remain a basic-rate taxpayer because you are below the £50,270 higher-rate threshold, so you keep the full Personal Allowance and £1,000 Personal Savings Allowance. A Plan 2 student loan charges 9% on earnings above £29,385, costing 9% of £12,615, about £1,135 a year. Because you are approaching the higher-rate band, pension contributions are useful both to save for retirement and to keep headroom below £50,270; salary sacrifice additionally cuts National Insurance. In Scotland the net figure is slightly lower because the Scottish higher rate of 42% starts at £43,662 and the intermediate 21% band applies, so a £42,000 Scottish salary pays a little more Income Tax than the rest of the UK.
