Tax planning in the UK has never been more relevant. By acting early, individuals or business owners can legally mitigate any exposure to tax liability by making use of relevant allowances, reliefs, and other practices that are HMRC-approved. In this article, we discuss operational and legal tax minimisation for the tax year 2025-26, as well as common pitfalls to consider.
What is Tax Planning? (and Why It Matters)
Tax planning, which is applicable to the tax planning for self-employed and business owners, is the process of getting your financial affairs in order to legally pay the minimum amount of tax, not tax evasion, but utilising the tax system to your advantage. Proper tax planning in UK will provide clarity in your cash flow, allow you to be compliant with HMRC rules, and limit the possibility of receiving an unexpected tax bill. Early tax planning is a key factor, because many tax relief opportunities are time-based.
Legal Methods to Decrease Your Tax Bill
1. Use Your Tax-Free Allowances Wisely
For the 2025‑26 year, your personal allowance is £12,570. High earners (over £100,000) may see part or all of their personal allowance calculated at a higher marginal tax rate (due to tapering). If you are able to reduce your adjusted net income, for example by making pension contributions, you will retain more of the personal allowance. Using these allowances effectively is a key part of personal tax planning services and can reduce your overall tax liability.
2. Maximise Pension Contributions and ISAs
The annual pension allowance is £60,000 for 2025-26 and the Lifetime Allowance, which previously capped how much a pension could grow tax-efficiently, has been removed. ISAs remain a tax-free method to save or invest, with an annual allowance of £20,000. Suitable combinations of these options will help to significantly reduce your taxable income.
3. Claim All Business Expenses
Self-employed and small business tax tips should each claim all necessary legitimate business expenses which are used “wholly and exclusively” for their business purposes. Common examples include, but are not limited to, office supplies, utilities, TRAVEL-expenses and professional fee deductions. Ideal record-keeping demonstrates that each of these deductions is fully supported if they were to be audited by HMRC.This becomes even more crucial in tax planning for self-employed individuals, where every deductible expense directly reduces taxable profit.
4. Salary and Dividend Planning (for Company Directors)
Company directors can take a combination of a salary and dividends. In 2025-26, the dividend allowance is £500 and dividends above this allowance will be taxed at, for example, 8.75% for basic rate taxpayers, 33.75% for higher rate taxpayers and 39.35% for additional rate taxpayers. For your overall tax liability to be diminished, you should consider the ideal combination of salary and dividends but the model approach would be to run the models for your own individual circumstances.
5. Make Use of the Annual Investment Allowance (AIA)
Under the AIA, business tax advice UK can fully deduct all qualifying capital expenditure on plant or machinery (up to a limit of £1 million per annum, if applicable).
Timing is important. Many businesses also benefit from structured business tax advice London, especially when planning large purchases or forecasting taxable profits. Early advice ensures allowances like the AIA are used efficiently instead of rushed at year-end.
6. Explore R&D Tax Credits and Reliefs
The R&D tax relief scheme was recently reformed from 1st April 2024. Businesses now meet qualification criteria for a merged scheme of 20% above-the-line credit. If you are a small or medium-sized enterprise (SME) who is R&D intensive, you can also receive cash credit at 14.5% on losses surrendered. It is important that you keep good records of all qualifying R&D activity and expenditure in order to claim relief.
Common Mistakes to Avoid
- Many tax savings opportunities due to timing are sensitive to specific dates.
- Deductions may be lost by not keeping accurate records.
- Planning may involve tax allowances and tax reliefs; evasion is illegal.
- A specialist tax accountant London or tax adviser Ashford can ensure accurate advice tailored to you, as well as give you peace of mind.
- Not consulting local tax preparers who understand region-specific rules, deadlines, and reliefs.
