Freelancing in the UK gives you freedom—no boss, no fixed hours—but tax time can be stressful. Many freelancers miss out on saving money just because they don’t know what business expenses they can claim. In the U.K , sole traders often work as freelancers or contractors. Unlike limited liability companies, they are required to pay taxes on their incomes and earnings directly. This means you must calculate and report what you owe to HMRC.

Imagine you’re working on a project at your favourite café. That coffee, the Wi-Fi, even your train ticket to get there—did you know you could claim those as tax deductions? Most people don’t! But don’t worry, We’ve got you covered. Let’s go through the top 10 business tax deductions every UK freelancer should know to save more and stress less.

What Do Tax Deductions Mean?

Tax deductions reduce the portion of your income subject to taxation, ultimately lowering your tax bill. For UK freelancers, this means you can subtract eligible business expenses—like office supplies, travel costs, or marketing fees—from your income before calculating what you owe to HMRC.

According to a study by QuickBooks, 47% of freelancers in the UK are unaware of all the expenses they can claim as deductions, resulting in higher tax payments than necessary. This highlights the importance of understanding and leveraging tax deductions to keep more of your earnings.
