As the 5 April 2026 deadline approaches, many individuals risk overlooking significant opportunities to structure their finances more tax-efficiently. Effective year-end planning involves utilising available allowances, reliefs, and exemptions to safeguard your overall wealth.

The following core pillars represent the most impactful actions to consider before the current tax year concludes. Exactly what’s best for you will depend on your circumstances. Please see below for our disclaimer.

1. Maximising Pension Contributions

Pensions remain one of the most sophisticated tools for immediate tax mitigation. Contributions effectively receive a government “top-up” through tax relief; for example, a £80 contribution is increased to £100 for basic rate taxpayers.

Annual Allowance: For the 2025/26 tax year, the total combined contribution limit (employer and employee) is £60,000 for most individuals.

In addition: Your own tax-relievable contributions are capped at or 100% of your relevant UK earnings or £3,600, whichever is lower.

Carry-Forward: You may be able to utilise unused allowances from the previous three tax years, providing a valuable opportunity for significant one-off contributions.

2. Utilising ISA Allowances

The Individual Savings Account (ISA) is a cornerstone of long-term wealth accumulation, as all interest, dividends, and capital gains generated within the wrapper are tax-free.

Annual Limit: Each adult has a £20,000 allowance for the 2025/26 year.

“Use it or Lose it”: Unlike pensions, unused ISA allowances cannot be carried forward. Failure to act by midnight on 5 April results in the permanent loss of that year’s allowance.

3. Proactive Capital Gains Tax (CGT) Management

Sound CGT planning involves deliberate, timed decisions to avoid unexpected future liabilities.

Exemption Limit: The annual CGT exemption for 2025/26 is £3,000.

Strategic Planning: If you have assets showing a profit, you might consider selling enough to realise gains up to the £3,000 threshold before 5 April. If repeated annually, this strategy can help manage portfolio growth in a highly tax-efficient way.

Additional Information: You may also be able to look at more complex strategies, like offsetting gains against losses or transferring assets between spouses to utilise both your allowances – This can be quite a complex area so consulting an adviser is essential to ensure this is done correctly.

4. Inheritance Tax and Gifting

Proactive gifting can significantly reduce potential Inheritance Tax (IHT) liabilities for your beneficiaries.

Annual Exemption: You can gift up to £3,000 per tax year immediately outside of your estate. Your £3k annual exemption can also carry forward (but only a maximum of once).

Small Gifts: Unlimited gifts of up to £250 per person are also permitted, provided they have not received a gift from your primary annual exemption.
