10 Tax Year End Tax Planning Tips for UK Individuals Before 5 April

Introduction

The UK tax year runs from 6 April to 5 April, which means many valuable tax planning opportunities disappear once the deadline passes.

If you take action before 5 April, you may be able to reduce your tax bill, use allowances that would otherwise be lost, and improve your long-term financial position.

Many taxpayers leave planning too late. However, even in the final weeks of the tax year there are still several legitimate ways to improve your tax position.

This guide explains 10 tax year end tax planning tips for UK individuals that may help reduce your overall tax exposure. These ideas can be relevant for employees, landlords, investors, business owners and company directors.

The key is to review your position before the tax year closes, because once the new tax year begins many opportunities cannot be reclaimed.

1. Use Your ISA Allowance

One of the most straightforward tax year end planning opportunities is using your Individual Savings Account (ISA) allowance.

For the current tax year, individuals can contribute up to £20,000 into ISAs. This allowance cannot be carried forward. If it is not used before 5 April, it is lost permanently.

ISAs are attractive because:

• interest is tax free
• dividends are tax free
• capital gains are tax free

This makes ISAs particularly useful for individuals who already use their personal savings allowance or dividend allowance.

There are several types of ISA available, including:

• Cash ISAs
• Stocks and Shares ISAs
• Lifetime ISAs
• Innovative Finance ISAs

If you have investments outside an ISA wrapper, it may also be worth considering transferring them into an ISA over time using “Bed and ISA” strategies.

2. Make Pension Contributions

Pension contributions are one of the most powerful tax planning tools available to UK taxpayers.

Personal pension contributions normally qualify for tax relief at your marginal rate.

This means:

• Basic rate taxpayers receive 20% relief
• Higher rate taxpayers can claim 40% relief
• Additional rate taxpayers may receive 45% relief

For many individuals, pension contributions can:

• reduce taxable income
• bring income below key tax thresholds
• restore lost allowances

For example, individuals earning over £100,000 may lose their personal allowance gradually. Pension contributions can sometimes reduce adjusted income and restore part of that allowance.

The annual pension allowance is normally £60,000, although tapering rules can apply for higher earners.

Unused allowances from the previous three tax years may also be available under carry forward rules, subject to conditions.

3. Use Your Capital Gains Tax Allowance

If you hold investments outside tax wrappers, it may be possible to realise gains within the annual Capital Gains Tax (CGT) allowance.

For the current tax year the annual CGT exempt amount is £3,000 for individuals.

This means you can realise gains up to this amount without paying Capital Gains Tax.

Some investors use a strategy called “Bed and ISA” or “Bed and Spouse”, where assets are sold and then repurchased in a tax-efficient structure.

This allows gains to be realised within the annual allowance while maintaining the underlying investment.

Once the tax year ends, unused CGT allowances cannot be carried forward.

4. Consider Transferring Assets to a Spouse

Spouses and civil partners can transfer assets between themselves without triggering Capital Gains Tax.

This rule creates opportunities to:

• use both partners’ CGT allowances
• make use of lower tax bands
• shift investment income to a lower-taxed partner

For example, if one spouse pays tax at 40% while the other is a basic rate taxpayer, transferring income-producing assets may reduce the household tax bill.

This approach is commonly used with:

• investment portfolios
• shares
• property interests

Professional advice is recommended before making transfers, particularly where ownership and beneficial interest rules may apply.

5. Review Dividend Income

Dividend income is taxed separately from employment income and other forms of earnings.

For the current tax year the dividend allowance is £500.

Dividends above this level are taxed at different rates depending on your income band.

For company shareholders and directors, it may be worth reviewing:

• the timing of dividend payments
• how much income is taken before 5 April
• whether unused basic rate bands remain available

Careful timing of dividends across tax years can sometimes reduce the overall tax liability.

6. Check Whether Marriage Allowance Applies

The Marriage Allowance allows certain couples to transfer part of their personal allowance to their spouse.

This can apply where:

• one partner has income below the personal allowance
• the other partner is a basic rate taxpayer

The allowance allows up to £1,260 of personal allowance to be transferred.

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

Marriage Allowance claims can also be backdated for up to four tax years if eligibility existed previously.

7. Make Charitable Donations Using Gift Aid

Charitable donations made under Gift Aid can also provide tax advantages.

When a UK taxpayer makes a donation under Gift Aid:

• the charity can claim basic rate tax relief
• higher and additional rate taxpayers can claim further relief through their tax return

Donations can also be carried back to the previous tax year in certain circumstances if the election is made in the tax return.

For individuals close to tax thresholds, Gift Aid can also reduce adjusted net income, which may help preserve allowances.

8. Review Your Tax Band Position

The end of the tax year is a good time to review where your total income sits within the tax bands.

Small changes to timing can sometimes prevent income spilling into a higher tax band.

Examples might include:

• delaying bonuses
• adjusting dividend timing
• making pension contributions

Crossing into a higher band can trigger higher tax rates on additional income, so understanding where you sit before 5 April can be valuable.

9. Use Junior ISA Allowances

If you have children, you may also wish to review Junior ISA allowances.

The Junior ISA allowance is currently £9,000 per child per tax year.

Like standard ISAs, this allowance cannot be carried forward.

Funds held in a Junior ISA grow free of:

• income tax
• dividend tax
• capital gains tax

This makes Junior ISAs an efficient long-term savings vehicle for children.

10. Check Your Tax Records and Claims

Finally, the tax year end is a good opportunity to review whether you have claimed all available reliefs.

Examples might include:

• employment expenses
• professional subscriptions
• working from home allowances
• property expenses for landlords
• allowable business expenses for self-employed individuals

Ensuring records are complete before the tax year closes can help avoid missed reliefs.

Key Takeaways

• The UK tax year ends on 5 April, and many allowances cannot be carried forward.

• Using allowances such as ISAs, pensions and CGT exemptions before the deadline can reduce tax.

• Couples may benefit from transferring assets or using Marriage Allowance.

• Reviewing your income levels and tax bands before the year end can help avoid unnecessary higher-rate tax.

Frequently Asked Questions

When does the UK tax year end?

The UK tax year runs from 6 April to 5 April each year. This means the tax year end always falls on 5 April, with the new tax year beginning on 6 April. Many tax allowances apply only within a single tax year, so any unused allowances are usually lost once the deadline passes. Reviewing your tax position before this date allows you to use available reliefs and allowances effectively.

What tax planning should I do before 5 April?

Before the tax year ends, it is sensible to review whether you have used key allowances such as your ISA allowance, pension contribution limits and Capital Gains Tax allowance. You may also want to check whether transferring assets to a spouse or making charitable donations could reduce your tax liability. Reviewing income levels and tax bands can also highlight planning opportunities.

How can I reduce my tax bill before the tax year ends?

Reducing your tax bill before the tax year end often involves using available reliefs and allowances. Examples include contributing to pensions, using ISA allowances, realising capital gains within the annual exemption and making Gift Aid donations. In some situations, adjusting the timing of income or expenses may also reduce the overall tax liability.

Are pension contributions tax deductible before the tax year ends?

Pension contributions normally qualify for tax relief at your marginal rate. Basic rate relief is applied automatically within many pension schemes, while higher rate or additional rate relief can usually be claimed through a Self Assessment tax return. Contributions made before the tax year end count towards that year’s annual allowance.

Should I use my ISA allowance before the tax year end?

Using your ISA allowance before 5 April ensures you do not lose that year’s tax-free investment capacity. Funds held in ISAs can grow free from income tax, dividend tax and Capital Gains Tax. If the allowance is not used before the tax year ends, it cannot be carried forward.

Can I transfer allowances to my spouse before the tax year ends?

Certain tax allowances can be shared or utilised through transfers between spouses. For example, assets can be transferred without triggering Capital Gains Tax, which may allow both partners to use their CGT exemptions. Marriage Allowance may also apply where one partner has unused personal allowance.

Can Capital Gains Tax be reduced before the tax year ends?

Capital Gains Tax may be reduced by using the annual CGT exemption, currently £3,000. If you realise gains within this limit during the tax year, no CGT is payable on those gains. Planning before the tax year end allows investors to manage gains more effectively.

What happens if I miss tax year end planning opportunities?

If allowances such as ISA subscriptions or CGT exemptions are not used before 5 April, they are generally lost and cannot be carried forward. This means missing the deadline may result in higher tax in future years. Planning ahead allows taxpayers to make full use of the available reliefs.

Do landlords need to do tax planning before the tax year ends?

Yes. Landlords may benefit from reviewing property income, allowable expenses and capital gains positions before the tax year ends. Timing certain costs or reviewing ownership structures can sometimes improve the overall tax outcome.
