Quick note: the UK 2025–26 tax year runs from 6 April 2025 to 5 April 2026 — and many year-end opportunities will disappear after 5 April 2026. GOV.UK

Here’s a short, practical checklist of things business owners and individuals can still consider this tax year 👇

The adult ISA allowance for the 2025–26 tax year remains £20,000 — tax-free interest, dividends and gains. If you have spare cash, consider topping up your ISA before 5 April.

The junior ISA allowance is £9,000, also with tax-free interest and gains. If you have any children / grandchildren and have some additional spare cash, consider topping up their ISA’s, please bare in mind that there may be a conversation to be had with regards to Inheritance Tax Gifts if it isn’t gifted out of Surplus Income.

• You can contribute up to £60,000 (or 100% of your earnings if lower).

• Contributions get tax relief at your highest marginal rate.

• Company directors can also make employer contributions through the business for extra efficiency.

If you run a company, timing when you take dividends or bonuses can affect which tax year they fall into — and how much tax you pay. Talk to your adviser to see whether taking income before or after 5 April makes sense for your position.

• The Capital Gains Tax annual exemption is £3,000 in 2024–25.

• Selling shares or assets before year-end could save you tax.

• Couples can transfer assets to use both allowances.

• Marriage Allowance — worth up to £252 if one of you earns below the personal allowance.

• Watch for the High-Income Child Benefit Charge if your income is over £50,000 — pension contributions could help reduce it.

• Buying planned equipment or investing in improvements now could reduce your profit for this year.

• Qualifying purchases may benefit from full expensing or the Annual Investment Allowance.

From 6 April 2026, some sole traders and landlords with qualifying income above £50,000 will have to keep digital records and make quarterly submissions under MTD for Income Tax. If you’re near that threshold, it’s sensible to start switching to compatible software now.

Once 5 April passes, many opportunities are gone for good. Acting now means:
✅ More control over your tax bill
✅ Better cash flow planning
✅ Less stress in the new year
