UK Income Tax Guide (Rates, Brackets, Allowances 2026/27)

Income Tax Rates 2026/27

There are three main Income Tax bands in England, Wales, and Northern Ireland for 2026/27. The basic rate of 20% applies to income between £12,571 and £50,270. The higher rate of 40% applies to income between £50,271 and £125,140. The additional rate of 45% applies to income above £125,140. Scotland sets its own Income Tax rates, with different bands — typically five bands ranging from 19% to 48%. Welsh rates align with England and Northern Ireland.

These thresholds have been frozen until at least 2028, which means "fiscal drag" is pulling more people into higher tax brackets as wages rise. The personal allowance is also frozen at £12,570. A person earning £50,000 in 2026/27 pays about £7,486 in Income Tax and about £4,764 in National Insurance — a combined marginal rate of about 32% for basic rate and 42% for higher rate earners.

Personal Allowance

The standard personal allowance is £12,570 for 2026/27. This is the amount you can earn before paying any Income Tax. The allowance begins to reduce once your income exceeds £100,000 — it reduces by £1 for every £2 of income over £100,000. This means anyone with income above £125,140 receives no personal allowance at all (a marginal rate of 60% on income between £100,000 and £125,140).

The marriage allowance lets you transfer up to 10% of your personal allowance to your spouse or civil partner — up to £1,260 in 2026/27. The transfer saves the receiving spouse up to £252 in tax. Both partners must have been born after 6 April 1935, one must be a non-taxpayer, and the other must be a basic-rate taxpayer. The blind person's allowance is £2,870, available to registered blind or partially sighted individuals.

Tax Codes

Your tax code tells your employer how much tax-free pay to give you. The most common code is 1257L, which gives the standard personal allowance of £12,570. If you have a second job or pension, you might have a BR (basic rate) code, meaning all pay is taxed at 20%. D0 means all pay is taxed at 40%, used for higher-rate second jobs. Emergency codes (like 1257L W1/M1) are used when HMRC does not have enough information — these are temporary and should be corrected.

You can check your tax code on the HMRC app or your personal tax account. If your code is wrong, you could be paying too much or too little tax. Common reasons for code changes include company benefits (car, health insurance), state pension deductions, under- or over-payments from previous years, and adjustments for untaxed interest or dividends.

What Counts as Income

Taxable income includes employment salary, self-employment profits, pension income (state and private), rental income from property, savings interest above the allowance, dividends above the allowance, state pension, and most state benefits (except some disability benefits). Different types of income are taxed in a specific order: earned income first, then savings income, then dividends.

Some income is tax-free: up to £1,000 from self-employment under the trading allowance, up to £7,500 from renting out a room in your home under the rent-a-room scheme, National Savings Certificates interest, Premium Bond prizes, ISAs (all income and gains), and certain state benefits like Universal Credit and Child Benefit. Understanding which income is taxable and which is not is the first step in effective tax planning.

PAYE vs Self-Assessment

Under PAYE (Pay As You Earn), your employer deducts Income Tax and National Insurance automatically from your wages based on your tax code. This is the simplest arrangement — most employees never need to file a tax return. Self-Assessment is required if you are self-employed with profits over £1,000, a company director, receive rental income, have capital gains to report, earn over £100,000, have foreign income, or need to claim certain reliefs.

The Self-Assessment filing deadline is 31 January following the end of the tax year. For the 2025/26 tax year, the deadline is 31 January 2027. Paper returns must be filed by 31 October. Late filing attracts an immediate £100 penalty. See our Self-Assessment guide for a step-by-step walkthrough.

Salary Sacrifice and Benefits in Kind

Salary sacrifice is an arrangement where an employee gives up part of their salary in exchange for a non-cash benefit. The most common salary sacrifice benefits are pension contributions (the most tax-efficient — you save both Income Tax and National Insurance), cycle-to-work schemes, workplace nursery schemes, and electric vehicle schemes. By sacrificing salary, you reduce your taxable income, saving Income Tax at your marginal rate (20%, 40%, or 45%) and National Insurance (10% or 2%). The employer also saves 15.05% employer NI, and many employers share this saving with employees through higher pension contributions or other benefits.

Benefits in kind (BIKs) are non-cash benefits provided by an employer that are taxable. Examples include company cars (especially with private fuel), private medical insurance, low-interest loans, and gym memberships. These are reported through the P11D form and taxed at your marginal rate based on the cash equivalent value. For company cars, the BIK rate depends on the car's CO2 emissions — electric cars have a very low BIK rate (2% in 2026/27), making them highly tax-efficient. When considering salary sacrifice schemes, check whether the benefit triggers a BIK charge — if it does, the overall saving may be less attractive. Pension contributions, cycle-to-work, and workplace nurseries are exempt from BIK, making them the most efficient salary sacrifice options.

Reducing Income Tax

Pension contributions reduce your taxable income at your marginal rate. If you earn £60,000 and contribute £10,000 to your pension, your taxable income falls to £50,000 — saving you £4,000 in tax (40% of £10,000). Salary sacrifice arrangements let you exchange salary for non-cash benefits like additional pension contributions, cycle-to-work schemes, or childcare vouchers — reducing both Income Tax and National Insurance.

The marriage allowance can save basic-rate couples up to £252 per year. EIS and SEIS investments offer 30% and 50% Income Tax relief respectively, though these are high-risk investments. The rent-a-room scheme gives £7,500 of tax-free rental income from a lodger. The trading allowance gives £1,000 of tax-free self-employment income. Gift Aid donations extend your basic rate band, giving higher-rate taxpayers relief at their marginal rate.

For higher earners, the most powerful Income Tax reduction strategy is keeping your adjusted net income below £100,000 to preserve the full personal allowance. Every £2 of income over £100,000 costs you £1 of personal allowance — a 60% effective marginal rate on the band between £100,000 and £125,140. Pension contributions and charitable donations are the most common ways to reduce adjusted net income below this threshold. A £10,000 pension contribution by someone earning £110,000 brings their income to £100,000, saving them £4,000 in higher-rate tax plus £5,000 from the restored personal allowance — a total saving of £9,000 on a £10,000 contribution. This 90% effective relief makes pension contributions extraordinarily valuable for those in the £100k-£125k bracket.

National Insurance Interaction

Income Tax and National Insurance are collected together through PAYE for employees. In 2026/27, the main NI rates are: employee Class 1 NI at 10% on earnings between £12,570 and £50,270, and 2% above £50,270. Employer NI is 15.05% on earnings above £9,100. For the self-employed, Class 4 NI is 9% on profits between £12,570 and £50,270 and 2% above. Understanding the combined tax burden (Income Tax + NI) is important for financial planning. A higher-rate taxpayer earning £60,000 as an employee pays about 40% Income Tax plus 2% NI on the top slice — a marginal rate of 42%. A basic-rate taxpayer pays 20% Income Tax plus 10% NI — a combined marginal rate of 30%.

The personal allowance abatement creates a 60% marginal rate band between £100,000 and £125,140. If you earn £110,000, you lose £5,000 of your personal allowance (half the excess over £100,000), meaning you pay tax on an extra £5,000 of income at 40%, plus 2% NI — effectively a 60% marginal rate on that portion. This is one of the most punitive tax traps in the UK system. Pension contributions are the most common way to reduce adjusted net income below £100,000, reclaiming the personal allowance and saving up to 60% marginal tax. Salary sacrifice and charitable donations via Gift Aid also reduce adjusted net income for personal allowance purposes.

Tax on Savings and Investments

Interest from savings accounts, bonds, and peer-to-peer lending is taxed as savings income. The personal savings allowance means basic-rate taxpayers can earn up to £1,000 in interest tax-free, higher-rate taxpayers £500, and additional-rate taxpayers nothing. There is also a starting rate for savings of up to £5,000 at 0%, available if your non-savings income (employment, pension, self-employment) is below £17,570. Dividend income has its own tax regime and allowance of £500. Capital gains on investments have a separate annual exempt amount of £3,000. Understanding the different tax treatments of different income types is critical for tax-efficient investing — which assets to hold in which accounts and when to use tax-advantaged wrappers like ISAs and pensions.

If you have significant savings and investments held outside ISAs and pensions, you may need to file a Self-Assessment tax return each year to report the income and gains. HMRC also collects data directly from banks and investment platforms through the Common Reporting Standard (CRS) and automatic exchange of information, so they are increasingly aware of your financial picture. Keeping accurate records of your interest, dividends, and capital gains throughout the tax year makes the Self-Assessment process much smoother.
