The end of the tax year is one of the most valuable planning opportunities available to you. Many tax allowances reset every year. If you don’t use them before 5 April, you lose them permanently. This checklist walks you through the key financial planning actions you should consider now to make your money work harder and avoid unnecessary tax.
As always, talk to your financial adviser to get advice that is relevant to your personal situation.
Why end-of-tax-year planning matters
Acting before the tax year ends allows you to use allowances that cannot be carried forward. Small adjustments made now can reduce income tax, capital gains tax and inheritance tax exposure while strengthening your long-term financial plan. The goal isn’t simply to save tax this year. It’s to make decisions that support your future lifestyle, retirement and family wealth.

Review your income and tax bands
Start by understanding where your income sits this tax year. If your income approaches higher-rate or additional-rate thresholds, planning opportunities often appear. Check whether you are fully using your personal allowance and whether income near or over £100,000 is reducing it through the personal allowance taper.
Pension contributions or charitable giving can sometimes restore lost allowances. Review income across your household. If a spouse or partner pays a lower rate of tax, holding income-producing assets in the right name can improve overall efficiency. If you receive dividends or savings income, confirm that available allowances are being fully used. If your household claims Child Benefit, review income levels carefully to avoid unexpected tax charges.
Making Gift Aid donations before 5 April can be a simple but effective planning step. Donations extend your basic rate tax band, which may help reduce higher-rate tax or restore lost personal allowance for higher earners.
Use your ISA and tax-efficient investment allowances
Your ISA allowance resets every tax year. Investments held within an ISA grow free from income tax and capital gains tax, making them a core building block of long-term planning. If appropriate for your risk profile, you may also consider tax-efficient investment structures designed to encourage investment into growing businesses. These investments can offer attractive tax reliefs but should always sit within a diversified strategy aligned to your financial plan.
Families may also wish to consider Junior ISAs and pension contributions for children. Starting early allows investments to benefit from long-term compounding while making use of valuable annual allowances.
Maximise pension contributions before year end
Pension contributions remain one of the most effective ways to reduce taxable income while building future financial security. Review how much has already been contributed this year, including employer payments. You may still have scope to contribute more and receive valuable tax relief. Unused pension allowances from the previous three tax years may also be available, creating significant planning opportunities.
Higher earners should check whether tapered allowances apply to avoid unexpected tax charges. Pension planning increasingly overlaps with inheritance tax planning, meaning decisions made today can influence how wealth passes to future generations.
Consider capital gains planning opportunities
Every individual has an annual capital gains tax exemption. If you hold investments with unrealised gains, selling and reinvesting may allow you to use this allowance efficiently. Couples should consider coordinating disposals so both exemptions are used. If you are planning to sell property or business assets, timing matters. Certain property disposals require reporting and payment shortly after completion, so early planning avoids unnecessary pressure and potential penalties.
Review inheritance tax planning early
Inheritance tax planning works best when started early. Check that your will reflects your current wishes and takes advantage of available allowances. Consider whether you have used your annual gifting allowance and review whether regular gifts from surplus income are being documented correctly. When structured properly, these gifts can fall immediately outside your estate for inheritance tax purposes. Lifetime planning decisions can significantly reduce future inheritance tax liabilities when implemented gradually over time.
Check trusts, family planning and longer-term structures
If you have established a trust or act as a trustee, confirm that reporting obligations are being met and that the structure still supports your goals. Tax rules evolve regularly, so periodic reviews ensure planning arrangements remain effective and compliant.
Review your National Insurance record and State Pension
If you are nearing retirement, review your National Insurance record and State Pension forecast. Your State Pension entitlement depends on your contribution history, and gaps may still be filled through voluntary contributions. Addressing shortfalls early can materially increase guaranteed retirement income. The most important step: act before 5 April
End-of-tax-year planning is not about last-minute tax avoidance. It’s about making informed decisions while opportunities remain available. Reviewing your position now allows you to reduce tax efficiently, improve long-term outcomes and ensure your financial plan stays aligned with your goals.
