Income Tax — England, Wales & Northern Ireland (2026/27)
- Personal Allowance £12,570. Basic rate 20% on the next £37,700, higher rate 40% from £37,701 to £125,140 of taxable income, additional rate 45% above £125,140.
- The Personal Allowance is reduced by £1 for every £2 of income above £100,000, so it disappears at £125,140. This calculator applies that taper.
Income Tax — Scotland (2026/27)
Scotland sets its own bands and rates for non-savings income. This calculator applies the Scottish bands shown in the source below. The Personal Allowance is the same UK-wide figure and the same £100,000 taper applies.
National Insurance (Class 1, category A)
- 8% on earnings between the Primary Threshold (£12,570 a year) and the Upper Earnings Limit (£50,270 a year).
- 2% on everything above the Upper Earnings Limit.
- National Insurance is charged on earnings after a net-pay pension deduction is not applied — NI is calculated on gross pay unless you use salary sacrifice. This calculator charges NI on gross pay, which is the more common arrangement.
Student loans (2026/27 thresholds)
- Plan 1 — 9% above £26,900. Plan 2 — 9% above £29,385. Plan 4 — 9% above £33,795. Plan 5 — 9% above £25,000.
- Postgraduate loan — 6% above £21,000, charged in addition to any of the above.
What this does not cover. This is an annual estimate for a single employment with a standard tax code and no other income.
It does not model emergency or non-standard tax codes, the Marriage Allowance, Blind Person's Allowance, benefits in kind (P11D),
the High Income Child Benefit Charge, salary sacrifice, or the way PAYE spreads tax across the year — your monthly payslip will differ
and is reconciled over the tax year. Your employer's National Insurance is not a deduction from your pay and is not shown.
