Most Common Deductible Expenses in the UK

If you’re trying to shrink your tax bill, you need to know which costs the government lets you claim. The list isn’t endless, but the right deductions can add up to big savings. Below you’ll find the everyday items most people forget, plus the bigger expenses that can make a real difference.

Everyday Expenses You Can Claim

Small things add up fast. Work‑related travel, like mileage when you use your own car for business, is fully deductible. Keep a simple log of dates, miles, and purpose – a spreadsheet works fine. Same goes for professional fees: accounting, legal advice, or membership of a trade body can be written off as long as they’re directly tied to your work.

Big‑Ticket Deductions to Remember

Charitable donations are a classic deduction. If you give money to a registered UK charity, you can claim the amount on your self‑assessment return and reduce your taxable income. Even modest gifts matter – every pound counts.

Pension contributions are another heavyweight. Money you put into a personal pension or a workplace scheme is deducted before tax, which means you pay less now and boost your retirement pot. The government caps the amount you can claim each year, but most taxpayers stay well within the limit.

Home‑related costs can be tricky. While mortgage interest on your primary residence isn’t deductible, you can claim a portion of your home expenses if you run a business from a dedicated room. That includes a share of heating, electricity, and council tax. Just be sure the space is used exclusively for work.

Employment training and education that directly improve your job skills also qualify. Courses, exam fees, and even some textbooks can be claimed, provided they’re not just for personal interest.

When you’re unsure whether an expense qualifies, the safest move is to check the HMRC guidance or ask your accountant. A quick call can save you from a nasty surprise later.
