Two salaries, two shapes
The same rules treat salaries very differently depending on where they sit against the thresholds. At £30,000, the allowance shields a big share and total deductions come to £4,880 — an effective 16.3%. At £55,000, the higher rate and both NI bands are in play: £12,543, or 22.8%. The rate you feel is set by the shape, not the headline.
Worked example · £55,000, England, 2026-27
- Income tax: £9,432 — basic rate filled, then the higher rate on the remainder.
- National Insurance: £3,111 — the main rate to the upper limit, 2% beyond it.
- After tax: £42,457 a year, £3,538.12 a month.
The crossover points worth knowing
Three thresholds shape most UK salaries: where the allowance ends and tax begins, where the basic rate hands over to the higher rate (and NI eases at almost the same point), and where the allowance itself starts tapering at £100,000. Salaries near a threshold reward precision — a £1,000 difference can land on either side. Enter your exact figure rather than a round one.

The UK tax calculator tells this same story tax-first, with Scotland as a toggle. For planning around a monthly budget, the salary calculator leads with the per-payday figure, and the take-home pay calculator with the yearly one.
What’s included, and what isn’t
Every figure this calculator produces is an estimate. Here is exactly what it accounts for, and what it does not.
What’s included
- Income tax from the published GOV.UK bands — rest-of-UK or Scottish, band by band.
- The Personal Allowance, including its taper above £100,000.
- Employee Class 1 National Insurance at 8% between the thresholds and 2% above the upper limit.
- Conversion between annual, monthly and weekly figures.
What’s not included
- Pension contributions and salary sacrifice — on the roadmap; both reduce tax in ways this estimate does not yet show.
- Student loan repayments (Plans 1, 2, 4, 5 and postgraduate) — also on the roadmap.
- Tax code adjustments: benefits in kind, marriage allowance, blind person's allowance, K codes.
- Bonuses and other one-off pay, self-employment, dividends, and savings interest.
- Employer National Insurance and the apprenticeship levy, which cost your employer rather than you.
What this calculator assumes
- Uses the 2026-27 rates and thresholds published on GOV.UK (tax year 6 April 2026 to 5 April 2027).
- Applies the standard £12,570 Personal Allowance, tapered by £1 for every £2 of income above £100,000.
- Assumes a standard tax code with no adjustments, one employment, and the same pay all year.
- National Insurance uses the annual equivalents of the published thresholds; per-payday NI can differ by a few pounds.
- Scotland's six income tax bands are applied when selected. Welsh rates currently match England & NI.

Frequently asked questions
What does 'salary after tax' include?
Here it means gross salary minus income tax and employee National Insurance — the two deductions every UK employee shares. Pensions, student loans and other payslip lines vary by person and are deliberately excluded, with each exclusion stated, so the figure is a clean common baseline rather than a guess at your exact payslip.
Why do things change at £50,270?
Two systems pivot at almost the same point. Income tax steps from the basic to the higher rate, while National Insurance drops from its main rate to 2% — one deduction accelerates as the other eases. The net effect is a higher combined marginal rate, but a smaller jump than the 20-to-40 headline suggests. The band table shows both movements.
How much is a typical UK salary after tax?
Rather than quote a 'typical' figure that dates quickly, this calculator computes any salary against the current published rules. As orientation from the worked examples on this page: £30,000 and £55,000 produce very different effective rates, because the allowance shields a larger share of the smaller salary — the pattern that matters more than any single number.
Is a bonus taxed differently from salary in the UK?
It is taxed the same — added to your income for the year and taxed through the same bands — but it can be withheld differently in the month it lands, because payroll annualises that month's pay. A large bonus month often over-withholds and corrects later. Modelling bonus months properly is on the UK roadmap.
Should I compare job offers on gross or net?
Net — but net computed consistently. Run both offers through this calculator so the same rules and exclusions apply to each, then weigh the pension and benefits separately. A higher gross with weaker pension contributions can lose to a lower one; the after-tax line is where that comparison starts.
