Running a small business in the UK means wearing a lot of hats — and making sure you are not paying more tax than you need to is one of the most important. The good news is that there are several straightforward, HMRC-approved ways to legally pay less tax, and most business owners are simply not making full use of them. Here is a plain-English guide to what is available right now in 2026.
Claim Every Expense You Are Entitled To
This sounds obvious, but it is the most commonly missed opportunity. HMRC’s list of allowable expenses covers everything from your broadband bill to mileage, professional subscriptions, and home office costs. If you use part of your home for work, you can claim a proportion of your heating, electricity, and internet. If you use your car for business, you can claim back costs using HMRC’s approved mileage rates. Every expense you miss is money that goes to HMRC instead of staying in your business.
Get Smart About How You Pay Yourself
If you run a limited company, the way you take money out makes a huge difference to your tax bill. Most directors take a small salary — up to the personal allowance of £12,570 — and draw the rest as dividends. Dividends are taxed at lower rates than salary and attract no National Insurance. This is one of the most effective legal ways to pay less tax without having to do anything complicated. If your spouse or partner genuinely works in the business, paying them a salary can also make use of their personal allowance and reduce your overall tax burden.
Pay Into a Pension — It Reduces Your Tax Bill Too
Many business owners know pensions are good for retirement, but fewer realise they are also one of the best tax tools available. Employer pension contributions are a deductible business expense, which means they directly reduce your company’s taxable profits. If your company is paying corporation tax at 25%, every £1,000 you contribute to a pension saves £250 in tax. That is a return you simply cannot get anywhere else — and it is completely above board.
Do Not Overlook R&D Tax Credits
If your business spends time developing new products, processes, or even internal tools, you may qualify for R&D tax credits. HMRC’s scheme allows eligible businesses to claim back a significant portion of their development costs — either as a reduction in their tax bill or as a cash payment. Many small businesses assume R&D credits are only for tech companies, but they apply across a wide range of sectors. The savings can be substantial, and most business owners never even ask.
