The 2026/27 tax year started on April 6th. If your payslip looks slightly different this month — or you're trying to work out whether a new job offer is worth it — here's exactly how UK income tax and National Insurance are calculated, with worked examples at the salary levels most people actually earn.
How UK Take-Home Pay is Calculated
Working out your net pay can feel like a maze of thresholds and percentages whilst you're looking at your monthly payslip. However, the calculation follows a logical three-step process that HMRC applies to almost every employee in the country:
Step 1: Calculate your taxable income (Gross Salary minus your Personal Allowance of £12,570).
Step 2: Apply the appropriate income tax rate to that taxable income segment.
Step 3: Subtract National Insurance separately from your total gross income.
£35,000 worked example for 2026/27:
- Taxable income: £35,000 − £12,570 = £22,430
- Income tax (20%): £4,486 per year = £374 per month
- National Insurance (8%): (£35,000 − £12,570) × 8% = £1,794 per year = £150 per month
- Gross monthly: £2,917
- Monthly take-home: £2,917 − £374 − £150 = £2,393
- Effective tax rate: 17.9%
UK Tax Rates 2026/27 — Income Tax and National Insurance
Income Tax Bands
Based on your annual earnings after the Personal Allowance.
- £0 – £12,570: 0% (Personal Allowance)
- £12,571 – £50,270: 20% Basic Rate
- £50,271 – £125,140: 40% Higher Rate
- Above £125,140: 45% Additional Rate
National Insurance
(Class 1 Employee Contributions)
- Below £12,570: 0%
- £12,570 – £50,270: 8%
- Above £50,270: 2%
The personal allowance taper above £100,000 is one of the more counterintuitive parts of the UK tax system — and one of the main reasons high earners often favour pension contributions. Your allowance reduces by £1 for every £2 earned above £100,000, disappearing entirely at £125,140. This creates an effective marginal tax rate of 60% in that specific income bracket.

Scottish Income Tax 2026/27 — How It Differs
Scotland sets its own income tax rates through the Scottish Parliament, resulting in more bands than the rest of the UK. For a £35,000 salary, Scottish taxpayers pay slightly more income tax than their counterparts in England and Wales — roughly £70–£100 more per year depending on the exact bands in force. The Scottish system aims to be more progressive, but it does mean your monthly take-home might look a little thinner if you live north of the border. It's important to remember that National Insurance is unchanged, as it remains a UK-wide tax overseen by Westminster.

What About Student Loan Repayments?
Depending on when you started university, your student loan repayments can significantly impact your monthly budget. Here are the thresholds for 2026/27:
- Plan 1: 9% above £22,015/year
- Plan 2: 9% above £27,295/year
- Plan 4 (Scotland): 9% above £27,660/year
- Plan 5: 9% above £25,000/year
Plan 2 impact on a £35,000 salary:
(£35,000 − £27,295) × 9% = £693/year
This works out to £58/month less in your pocket. Many people are surprised by this deduction and feel like something has gone wrong with their payslip when they see their first graduate salary. However, it's just a standard part of the repayment scheme. One vital detail to note is that student loan deductions are calculated on your gross salary above the threshold — they don't reduce your taxable income or your National Insurance bill.
What If I Have Two Jobs or Other Income?
Managing multiple income streams can lead to confusion regarding your tax code. You'll often see emergency tax codes like BR (Basic Rate) or 0T on a second job because HMRC assumes you've already used your full Personal Allowance on your primary income. If your primary job doesn't use the full £12,570 allowance, you can contact HMRC to split it between your employers, but this does not happen automatically.
Always check the tax code on your payslip — it's usually found near your NI number. If it says BR, 0T, or ends in M1/W1 and you don't believe it should, you might be overpaying. For authoritative tax code queries or to update your estimated income, use the official tool at gov.uk/check-income-tax.

Frequently Asked Questions
How much tax do I pay on a £35,000 salary in the UK?
On a £35,000 salary in 2026/27, you pay £4,486 income tax and £1,794 National Insurance per year — a combined £6,280. Your monthly take-home is approximately £2,393, giving an effective tax rate of 17.9%.
What is the Personal Allowance for 2026/27?
The Personal Allowance for 2026/27 is £12,570. This is the amount you can earn before paying any income tax. It applies to most UK taxpayers in England, Wales, Northern Ireland, and Scotland.
How is National Insurance calculated in the UK?
Employee National Insurance in 2026/27 is charged at 8% on earnings between £12,570 and £50,270 per year, and 2% on anything above that. It is calculated separately from income tax — you pay both on the same earnings above £12,570.
Why did my take-home pay change in April 2026?
The 2026/27 tax year started on 6 April 2026. Any changes HMRC made to tax codes, thresholds, or National Insurance rates take effect from this date. If your payslip looks different, check your tax code letter — it should end in L for the standard personal allowance.
How does the 40% higher rate tax work in the UK?
You pay 40% income tax on earnings between £50,271 and £125,140 per year. Only the portion above £50,270 is taxed at 40% — not your entire salary. On a £60,000 salary, you pay 40% on just £9,730, adding £3,892 in higher-rate tax on top of the basic-rate bill.
What happens to my personal allowance if I earn over £100,000?
Your personal allowance reduces by £1 for every £2 you earn above £100,000. At £125,140 it disappears entirely. This creates an effective 60% marginal rate on income between £100,000 and £125,140 — the reason many high earners increase pension contributions to bring adjusted income below £100,000.
Do student loan repayments reduce my tax bill?
No — student loan repayments don't reduce your income tax or National Insurance. They are deducted from your gross salary above the plan threshold, but this does not count as a tax-deductible expense. On Plan 2 at a £35,000 salary, you pay an extra £58/month on top of your tax and NI deductions.
The UK tax system has more moving parts than most people realise — income tax, National Insurance, and potentially student loan repayments all interact separately. The 2026/27 tax year brought the new rates into effect on 6 April; if you want to run the exact numbers for your salary, our take-home pay calculator works through all three deductions together. You might also find it useful to convert your UK salary to an hourly rate if you're comparing a salaried role to freelance work. Time is the one thing you can't buy back, so knowing your true net earnings is vital for any life decision.
