📊 Income Tax Band Breakdown
How UK Income Tax Works — 2025–26
The UK uses a progressive tax system with a tax-free Personal Allowance and increasing rates on higher income bands. Here is everything you need to know for the 2025–26 tax year.
Personal Allowance — £12,570
Everyone in the UK gets a tax-free Personal Allowance of £12,570 — frozen until 2028. This means you pay no income tax on the first £12,570 you earn. If your income exceeds £100,000, the allowance tapers by £1 for every £2 earned above that threshold, reaching zero at £125,140 — creating an effective 60% marginal tax rate in this band.
Income Tax Bands (England/Wales/NI)
Basic Rate (20%): £12,571–£50,270. Higher Rate (40%): £50,271–£125,140. Additional Rate (45%): above £125,140. Like all progressive systems, only the income within each band is taxed at that rate — not your entire salary. These thresholds are frozen until April 2028 (fiscal drag increases tax takes over time).
Scottish Income Tax (6 Bands)
Scottish taxpayers have six bands for 2025–26: Starter 19% (£12,571–£15,397), Basic 20% (£15,398–£27,491), Intermediate 21% (£27,492–£43,662), Higher 42% (£43,663–£75,000), Advanced 45% (£75,001–£125,140), Top 48% (above £125,140). NI rates are the same as the rest of the UK.
National Insurance (Employee Class 1)
Employee NI is deducted in addition to income tax: 8% on earnings from £12,570 to £50,270 (Primary Threshold to Upper Earnings Limit), then 2% on all earnings above £50,270. There is no NI on earnings below £12,570. NI is calculated separately from income tax and does not benefit from the same personal allowance structure.
Employer NI — 15% from April 2025
Employers pay Class 1 NI at 15% on each employee’s earnings above the Secondary Threshold of £5,000/year (reduced from £9,100 in 2024–25). This is a cost to the employer on top of your salary. The Employment Allowance doubled to £10,500, helping smaller businesses offset their NI bill. Employers also pay Class 1A at 15% on benefits-in-kind.
Student Loan Repayments
Student loans are repaid through PAYE at 9% of earnings above your plan threshold: Plan 1 (£24,990), Plan 2 (£27,295), Plan 4 — Scotland (£31,395), Plan 5 (£25,000). Postgraduate loans are repaid at 6% above £21,000. Repayments are separate from income tax and NI, and you can have both undergraduate and postgraduate repayments deducted simultaneously.

Personal Allowance Tapering: If your income exceeds £100,000, your Personal Allowance reduces by £1 for every £2 earned above £100,000. Between £100,000 and £125,140, this creates an effective marginal rate of 60% (40% income tax + 20% lost allowance). Once income exceeds £125,140, the full allowance is lost. Pension contributions can be used to reduce income back below £100,000 to reclaim the allowance.
9 Legal Ways to Reduce Your UK Tax Bill
HMRC-approved strategies used by UK taxpayers to legally minimise their income tax liability.
Maximise Pension Contributions
Pension contributions receive tax relief at your marginal rate. A higher-rate taxpayer contributing £10,000 to a pension gets £4,000 back in tax relief — effectively costing only £6,000. Salary sacrifice also reduces NI. Annual allowance is £60,000 (or 100% of earnings if lower) for 2025–26.
Use Your ISA Allowance
Up to £20,000 per year can be saved or invested in an ISA, completely free of income tax and capital gains tax on returns. Cash ISAs protect savings interest; Stocks & Shares ISAs shelter investment gains. Interest and dividends within an ISA never appear on your tax return.
Marriage Allowance
If you or your spouse earns below the Personal Allowance (£12,570) and the other is a basic-rate taxpayer, you can transfer £1,260 of unused allowance — saving up to £252 per year. Apply via HMRC’s online service; you can also claim for up to 4 previous tax years.
Claim Working From Home Relief
Employees working from home can claim £6 per week (£312/year) without needing receipts, or the actual additional costs if higher. This reduces your taxable income. In prior years, millions of employees successfully claimed backdated WFH relief through HMRC’s online portal.
Salary Sacrifice for Benefits
Salary sacrifice arrangements for childcare vouchers, cycle-to-work schemes, electric vehicles, and pension contributions reduce your taxable income before PAYE is applied. This reduces both income tax and National Insurance. Electric cars via salary sacrifice attract very low Benefit-in-Kind rates.
Gift Aid Donations
Donations to charities under Gift Aid are treated as if you’ve paid basic rate tax. Higher-rate taxpayers can claim the difference between 40% and 20% on their Self Assessment return. Donating £1,000 to charity via Gift Aid is worth a further £200 tax relief for a 40% taxpayer.
Reduce Income Below £100,000
Incomes between £100,000 and £125,140 face an effective 60% marginal rate due to Personal Allowance tapering. Pension contributions, charitable donations, or salary sacrifice can reduce income below £100,000 to reclaim the full £12,570 allowance — worth up to £5,028 in tax saved.
Use Your Capital Gains Tax Allowance
Each tax year you get a £3,000 capital gains allowance (2025–26) tax-free. Plan asset disposals across multiple tax years to stay within the annual allowance. Spouses or civil partners can transfer assets between them at no gain/no loss, effectively doubling available allowance.
Check Your Tax Code
Millions of UK taxpayers are on the wrong tax code, overpaying PAYE. The standard code for 2025–26 is 1257L. If you have multiple jobs, company benefits, or underpaid tax, your code may be adjusted. Check your code via your Personal Tax Account on GOV.UK and contact HMRC if it looks wrong.
