How the £40,000 calculation works
UK Income Tax and NI are applied in stages. Here are the workings using 2025/26 HMRC rates.
Personal allowance
The first £12,570 of your salary is tax-free, signalled by tax code 1257L. So £27,430 of your £40,000 salary actually gets taxed.
Income Tax
All of your taxable income fits inside the basic-rate band (which runs to £50,270), so the full amount is taxed at 20%: £27,430 × 20% = £5,486.
National Insurance
NI is 8% on earnings between £12,570 and £50,270, then 2% above £50,270. Total NI on £40,000: £2,194.
Result
£40,000 − £5,486 − £2,194 = £32,319.60 take-home. Divide by 12 for the monthly figure of £2,693, or by 52 for the weekly figure of £622.
