What Tax Reliefs and Allowances Are Available in the UK Today?

Table of Contents

The UK tax system in 2026 is built around a combination of allowances and reliefs designed to reduce the amount of tax individuals pay legally. With thresholds largely frozen in recent years, effective tax planning has become more important than ever. By understanding how each allowance works and how they interact, individuals can significantly improve their financial efficiency and long-term wealth outcomes.

This guide provides a detailed breakdown of the key tax reliefs and allowances available in the UK today, along with practical strategies to maximise them.

Key UK Tax Allowances at a Glance (2026)

Allowance Type	Amount (2026/27)	Purpose
Personal Allowance	£12,570	Tax-free income threshold
ISA Allowance	£20,000	Tax-free savings and investments
Pension Annual Allowance	£60,000	Tax relief on retirement contributions
Capital Gains Tax Allowance	£3,000	Tax-free gains on asset disposals
Dividend Allowance	£500	Tax-free dividend income
Personal Savings Allowance	£1,000 / £500	Tax-free interest income
Marriage Allowance	£1,260 transfer	Reduces spouse’s tax liability

Personal Allowance: The Foundation of Income Tax

The Personal Allowance allows individuals to earn up to £12,570 per year without paying income tax. This threshold applies to most taxpayers and forms the basis of income tax calculations.

However, once income exceeds £100,000, the allowance is gradually reduced by £1 for every £2 earned above that level. This means it is completely withdrawn at £125,140, creating an effective marginal tax rate of 60% within that band.

Strategic considerations:

Individuals close to the £100,000 threshold may benefit from pension contributions or charitable donations to preserve their allowance
Salary sacrifice schemes can also help reduce taxable income

ISA Allowance: Tax-Free Growth and Income

The Individual Savings Account (ISA) remains one of the most effective tools for tax-efficient investing.

Annual allowance: £20,000
No tax on interest, dividends, or capital gains

Types of ISAs:

Cash ISA: Suitable for low-risk savers
Stocks and Shares ISA: Ideal for long-term investors seeking growth
Lifetime ISA: Offers a 25% government bonus on contributions up to £4,000 annually (subject to conditions)

ISAs are particularly valuable because all returns are completely shielded from tax, regardless of income level.

Planning insight:

Unused ISA allowance cannot be carried forward, making it essential to utilise it before the end of each tax year.

Pension Contributions: Long-Term Tax Efficiency

Pensions offer one of the most powerful forms of tax relief in the UK.

Annual contribution limit: £60,000
Tax relief is applied at the individual’s marginal rate

For example:

A basic-rate taxpayer contributing £80 receives £20 in tax relief, making a £100 total contribution
Higher-rate taxpayers can claim additional relief through self-assessment

Additional benefits:

Employer contributions are typically tax-efficient
Unused allowance can be carried forward for up to three tax years
Investments grow free from income tax and capital gains tax within the pension

Key consideration:

Access to pension funds is restricted until minimum retirement age, so this is a long-term strategy.

Capital Gains Tax Allowance

Capital Gains Tax (CGT) applies when you sell assets such as shares or property at a profit. However, each individual has an annual exempt amount.

CGT allowance (2026): £3,000

Gains below this threshold are not taxed, while amounts above it are taxed depending on your income band and asset type.

Planning strategies:

Spread disposals across multiple tax years to use multiple allowances
Transfer assets to a spouse to utilise both allowances
Use ISAs to eliminate future CGT liability

Dividend Allowance

Dividend income is taxed separately from salary or other income.

Tax-free dividend allowance: £500

Beyond this threshold, dividend tax rates apply based on income band.

Strategic approach:

Hold dividend-paying investments within ISAs to avoid tax entirely
Consider timing dividend payments to remain within lower tax bands

Personal Savings Allowance

Interest earned on savings outside ISAs may still benefit from tax-free thresholds.

£1,000 for basic-rate taxpayers
£500 for higher-rate taxpayers
No allowance for additional-rate taxpayers

Importance in 2026:

With higher interest rates in recent years, more savers are exceeding this allowance, increasing the importance of tax-efficient savings vehicles.

Marriage Allowance

Marriage Allowance allows one partner to transfer a portion of their unused Personal Allowance to their spouse or civil partner.

Transferable amount: £1,260

Eligibility:

Must be married or in a civil partnership
The receiving partner must be a basic-rate taxpayer

This relief can reduce the receiving partner’s tax bill by up to £252 per year.

Investment-Based Tax Reliefs

The UK government encourages investment in small and growing businesses through several tax-efficient schemes.

Enterprise Investment Scheme (EIS)

Up to 30% income tax relief on investments
Potential exemption from CGT on qualifying gains

Seed Enterprise Investment Scheme (SEIS)

Up to 50% income tax relief
Designed for early-stage startups

Venture Capital Trusts (VCTs)

Income tax relief of around 30%
Tax-free dividends

Risk considerations:

These schemes involve higher risk and are generally suited for experienced investors with diversified portfolios.

Additional Tax Relief Opportunities

Gift Aid on Charitable Donations

Donations are made from post-tax income but treated as pre-tax
Higher-rate taxpayers can claim additional relief

Blind Person’s Allowance

Provides an additional tax-free allowance for eligible individuals

Trading and Property Allowances

£1,000 tax-free allowance for small amounts of trading or property income

Practical Strategies to Maximise Tax Efficiency

Use Allowances Fully Each Year

Most allowances reset annually and cannot be carried forward. Failing to use them results in lost opportunities.

Combine Multiple Reliefs

Effective planning often involves layering strategies:

Use ISAs for tax-free growth
Contribute to pensions for tax relief
Manage CGT exposure through timing and asset allocation

Manage Income Thresholds

Tax thresholds significantly impact overall liability. Strategic planning around income levels can reduce exposure to higher tax bands and preserve allowances.
