5 Hidden Tax Reliefs Most UK Sole Traders Overlook (2026 Edition)

When running your own business, every pound matters. But what we tend to notice is that many sole traders are so busy with their own businesses that they end up paying more to HMRC than they actually owe.

With the new digital rules being introduced this year, keeping on top of your self assessment tax return in the UK has never been more crucial. At Wingate Accountants, we believe that you should only pay what’s necessary. To help you keep more of your hard-earned cash, we’ve compiled a list of five tax reliefs that are frequently missed.

The ‘Use of Home’ Calculation

If you work from your spare room or even just your kitchen table, you can claim a portion of your household bills. While many people know about the flat rate simplified expenses, you might actually save more by calculating the actual costs of your heating, electricity, and water based on the number of rooms you use for work. If your energy bills have climbed recently, this traditional method often results in a much higher deduction.

Professional Subscriptions and Magazines

Do you pay for a professional body membership to stay qualified? Or perhaps you subscribe to a trade magazine to keep up with industry trends? These are often overlooked because they feel like personal interests, but if they are wholly and exclusively for your trade, they are tax-deductible. Whether it is a LinkedIn Premium account for recruitment or a specialised journal, make sure you are tracking these small monthly costs.

Marketing and Website Maintenance

In 2026, your digital presence is your storefront. Many sole traders remember to claim for a big website redesign, but they forget the smaller, recurring costs. This includes your domain renewal fees, monthly hosting, and even small spends on social media advertising. When we help clients with their self-assessment tax return in London, we often find these digital micro-costs add up to hundreds of pounds over the year.

Training and Personal Development

You can claim for training courses that help you maintain or update your existing skills. If you are a graphic designer taking a course on the latest AI design tools, that is a business expense. However, be careful—HMRC usually doesn’t allow claims for learning a completely new skill that is unrelated to your current business. If it helps you do your current job better, we can likely include it.

Bad Debts

It is a frustrating part of business, but sometimes clients simply don’t pay. If you have an invoice that you know will never be settled, you can write it off as a bad debt. This ensures you aren’t paying tax on income that never actually hits your bank account.
