What Can I Claim as a Business Expense?

This is something we get asked all the time.

"Can I claim my phone?"

"What about my lunch?"

"Can I put my clothes through the business?"

The truth is, it's almost never a simple yes or no.

One of the biggest misconceptions is that there's a definitive list somewhere of everything you can and can't claim. In reality, tax doesn't work like that.

Instead of asking: "Can I claim it?"

A better question is: "Why am I buying it, and how does it relate to my business?"

Once you understand a few key principles, you'll start to see why the answer is so often, "It depends."

It's About the Purpose, Not the Purchase

One of the fundamental rules in UK tax is that an expense must be incurred wholly and exclusively for the purposes of your business. Whilst that might sound like technical jargon, the idea is actually quite simple.

Ask yourself: "Would I still be buying this if I didn't have my business?"

If the answer is no, that's a good indication the expense may have been incurred purely for business purposes.

If the answer is yes, then it may not be as straightforward.

This isn't a rule you can apply in isolation, but it's a useful starting point when considering whether something is likely to be an allowable business expense.

Understanding Dual Purpose

Another important principle is something called dual purpose.

This is where an expense has both a business purpose and a personal purpose.

For example:

• Ordinary clothing worn to work.

• Meals that also satisfy your personal need to eat.

• Home internet that's used for both work and family life.

Although these things may help you run your business, they also provide a personal benefit. That doesn't automatically mean they're not allowable, but it does mean the tax treatment often becomes more complex. It's one of the main reasons accountants so often answer questions with: "It depends."

Every Business Is Different

The same purchase can be treated differently depending on the business. A camera may be an essential tool for a professional photographer. For someone who runs a plumbing business, probably not.

A set of chef's knives could be fundamental to one business, while being entirely personal for another.

It's not just what you've bought that matters - it's why you've bought it and how it relates to your trade.

A Receipt Doesn't Make It Tax Deductible

Another common misunderstanding is that keeping a receipt means you can claim the expense. Unfortunately, that's not how it works. A receipt simply proves you spent the money. It doesn't determine whether the expense qualifies for tax relief.

The purpose of the expense is always the more important question.

Ask Before You Buy

If you're ever unsure, ask your accountant before making the purchase.

A quick conversation beforehand is often much easier than trying to justify an expense months later when your accounts are being prepared.

It can also help ensure you're claiming everything you're entitled to, whilst avoiding claims that could cause problems if HMRC ever asked questions.

The Bottom Line

There isn't a magic list of business expenses that applies to every business.

Tax is based on principles, not checklists. So next time you're wondering whether you can claim something, try asking yourself these three questions:

• Why am I buying it?

• Would I still buy it if I didn't have my business?

• Does it have a personal purpose as well as a business one?

Those questions won't answer every situation, but they'll help you understand why the answer is so often "it depends."

And if you're still unsure, don't guess - ask. That's exactly what we're here for.
