Why is my marginal rate 60% between £100,000 and £125,140?

Your Personal Allowance falls by £1 for every £2 of income above £100,000. Each extra £1 is taxed at 40% and also turns 50p of allowance into taxable income, so the effective rate is 60% (67.5% in Scotland). National Insurance adds 2%. Pension contributions can restore the allowance.

How is Scottish Income Tax different?

Scotland has six bands for 2026/27: 19%, 20%, 21%, 42%, 45% and 48%. People earning less than about £33,500 pay slightly less Income Tax than in the rest of the UK; higher earners pay more. National Insurance and student loans are the same everywhere.

What is the difference between a net pay arrangement and salary sacrifice?

Both give Income Tax relief at your top rate. Salary sacrifice also lowers the pay that National Insurance and student loan repayments are worked out on, so take-home pay is a little higher for the same contribution. Relief at source schemes are not covered in this version.

Why might my payslip differ from this estimate?

Payroll works out National Insurance and student loans for each pay period, your tax code may not be 1257L, and bonuses or benefits in kind change the figures. If you are over State Pension age you pay no employee National Insurance.

UK take-home pay 2026/27: Income Tax, National Insurance and student loans explained

Last updated 13 October 2026By the calcisland editorial team

A UK job offer is almost always a gross figure. Take-home pay is what remains after Income Tax, Class 1 National Insurance, any student loan, and any pension contribution. This guide covers tax year 2026/27 (6 April 2026 to 5 April 2027) for one employee job. It is general education, not tax advice. Figures were checked on 2026-10-05 against HMRC, gov.scot and Student Loans Company sources.

What is deducted from a UK salary in 2026/27?

Deduction	2026/27 rule	Notes
Personal Allowance	£12,570	Reduced by £1 for every £2 of adjusted net income over £100,000; zero from £125,140
Income Tax (England, Wales, NI)	20% / 40% / 45%	Basic, higher and additional bands
Income Tax (Scotland)	19%–48%	Six bands
Class 1 National Insurance	8% then 2%	0% to £12,570; 8% to £50,270; 2% above
Student loan	9% above the plan threshold	Plans 1, 2, 4 or 5
Postgraduate Loan	6% above £21,000	Can sit alongside an undergraduate plan
Pension	% of salary	Net pay arrangement or salary sacrifice

Wales set its rates at 10p in each band for 2026/27, so the combined result matches England. Northern Ireland uses the England bands. National Insurance, student loans and the Personal Allowance are UK-wide.

Take-home pay = gross salary − pension (if salary sacrifice or net pay) − Income Tax − Class 1 National Insurance − student loan − postgraduate loan

Under a net pay arrangement, the contribution lowers taxable pay only. Under salary sacrifice, it also lowers the pay used for National Insurance and student loans, so take-home is a little higher for the same percentage.

How does the Personal Allowance taper work?

Above £100,000 of adjusted net income, the £12,570 allowance shrinks by £1 for every £2. It reaches £0 at £125,140. Inside that band, each extra £1 is taxed at 40% and also removes 50p of allowance that is then taxed at 40%, so the effective Income Tax rate is 60% (67.5% in Scotland, where the income falls in the advanced band). Class 1 National Insurance adds another 2%.

Pension contributions reduce adjusted net income and can restore the allowance. Example UK-18: £110,000 with a 10% net-pay pension restores the full £12,570.

Worked example: £30,000 in England (UK-01)

Step	Calculation	Result
Gross salary		£30,000.00
Personal Allowance	full	£12,570.00
Taxable income	30,000 − 12,570	£17,430.00
Income Tax	17,430 × 20%	£3,486.00
Class 1 National Insurance	(30,000 − 12,570) × 8%	£1,394.40
Student loan	none	£0
Take-home pay	30,000 − 3,486 − 1,394.40	£25,119.60 a year

That is about £2,093.30 a month or £483.07 a week. The effective rate is 16.27%.

Other verified cases:

Case	Gross	Net / year
England £60,000	£60,000	£45,357.40
England £110,000 (PA taper)	£110,000	£72,357.40
Scotland £30,000	£30,000	£25,154.53
England £45,000, Plan 2	£45,000	£34,514.25
England £60,000, 5% net-pay pension	£60,000	£43,557.40
England £60,000, 5% salary sacrifice	£60,000	£43,617.40

Scotland pays a little less Income Tax than England below about £33,500 and more above that. The £35 difference at £30,000 (£25,154.53 vs £25,119.60) is the Scottish starter and intermediate bands at work.

What the calculator leaves out

These points are also listed on the calculator page:

Tax code 1257L only; other codes and emergency codes are not modelled.
Marriage Allowance, Blind Person’s Allowance, benefits in kind and the High Income Child Benefit Charge are excluded.
Relief at source pensions are not modelled.
Only one undergraduate loan plan at a time, matching how payroll deducts.
Figures are an even annual estimate; payroll rounds National Insurance and loans per pay period.
Employees over State Pension age pay no employee National Insurance; this version always deducts it.
Other income (second job, savings, dividends, property) is out of scope.

US take-home pay 2026: the North America counterpart (pubDate 10-11).
Japan take-home pay 2026: social insurance and resident tax on a Japanese salary.
