What Expenses Can A Sole Trader Claim In The UK?

Being a sole trader comes with a lot of perks, including being your own boss, not having to deal with copious amounts of red tape, and lots more. 

We could spend all day talking about the perks of being a sole trader, but today we want to focus on one in particular: allowable expenses.

Allowable expenses are costs that you can claim back from the HMRC. They’re a beautiful thing, but can also be a little bit sneaky as this process isn’t automatic. If you don’t know that something can be claimed back, you’re not going to claim for it.

A lot of sole traders assume that some allowable expenses aren’t for them, which means there could be loads of expenses you’ve been footing the bill for that you could be been offered relief for. We’re here to put an end to that. 

To make sure that you’re always getting the best deal for your business, we’ve put together this guide on what expenses can a sole trader claim and how you can start your claim today. Let’s get started.

What are allowable expenses?

First things first, allowable expenses are costs that businesses can claim back from the HMRC when submitting their annual returns. For limited companies, allowable expenses reduce their Corporation Taxes. For Sole Traders, allowable expenses can be claimed on your self-assessment tax return. 

There’s a keyword in here though and that’s ‘allowable’. You can’t claim expenses back unless they are allowed by the HMRC and fit the bill of being “wholly, exclusively, and necessary” for business purposes. 

Over the years, a lot of people have tried to fool the government into thinking their personal holidays, laptops, cars, etc are for ‘business purposes’. You can’t just write off anything you want, there are a lot of restrictions. Plus, we assume that you’ll never want to pull a fast one on the HMRC and be put at risk of hefty fines or investigations.  We’re here to do things by the book and let you in on the 100% legitimate expenses you can claim back for.

What expenses can a sole trader claim?

Before you get any ideas about submitting every kind of expense to the HMRC, let’s go over the allowable expenses that a sole trader can claim. 

1. Protective gear and equipment 

Protective gear is one of the expenses you can claim as a sole trader, but only if your work requires it.

If you need specialist equipment or PPE clothing because of your work, including steel toe boots or hard hats in construction, or hazardous suits for chemical handling, you will be able to claim these costs back. 

That’s a big win for safety. 

2. Training and courses

If you want to enrol in courses or pay for training to upskill yourself or aid your business, then you can claim this as another allowable expense. 

Just make sure they’re relevant and serve to actually advance your career or business. If you’re a plumber, the HMRC won’t pay for your ballet dance classes. Although if you could successfully combine plumbing and ballet, that will certainly be a fixture worth watching. 

3. Glasses & Contact Lenses

While directors of limited companies need to follow health and safety guidelines and therefore may be able to claim expenses on eye tests, sole traders do not have such a benefit.

That’s because there’s no legal requirement for you to follow health and safety requirements as a sole trader.

However, if you have been prescribed glasses or contact lenses specially for while you work – and you never need them at any other time. You may be able to claim ther cost as a legitimate business expense.

4. Financial costs 

This includes aspects like bank charges on business accounts or insurance policies. Again, this only relies on business use and doesn’t cover any personal loans or credit that you might have taken out.  

Also, if you don’t have insurance yet, now is a good time to think about getting yourself insured as a sole trader. 

5. Advertising and marketing 

Advertising your business is a way of getting clients and customers your way, the essential lifeblood of a sole trader. Certain advertising or marketing costs, such as a website cost, can be expenses back as a sole trader, helping to ease the burden of getting your business out there. 

If you’re not sure where to start with advertising, why not view the Business4Beginners blog for ideas and inspiration? 

6. General office costs

Every minor office need, including pens, paper, ink, postage, post-its, highlighters, envelopes, and more can be classed as an allowable expense for your office, provided that you need it to keep your office running.

You’ll also be able to expense any office equipment that you might need for business purposes, including computers, printers, label printers, and more. 

7. Accommodation and travel expenses 

If you have to travel for work, you can claim back the travel and accommodation expenses for this journey. This includes the full fair of any train or bus ticket you paid, or milage money back if you’ve travelled by car. 

These expenses come with the expectation that you pick out reasonable travel and accommodation. If you’re at a one-day conference, they won’t pay for a 5 nights stay in the Ritz. 

Can I claim for a business car lease as a sole trader?

A business car lease is a good answer to the question of what expenses can a sole trader claim in the UK.

If you’re a sole trader, you’re eligible to take out a business car lease instead of a personal one when selecting your business vehicle. Now, you can’t completely write off the cost of this lease, but you will be able to avoid paying any company car tax as there’s no legal difference between yourself and your company.

This could result in big savings – enough to get a free upgrade to a better model. 

As well as not paying any company car taxes, you will be able to expense the running costs of your car. This is done through a flat rate where you multiply a set cost by the number of miles that you travel, or through the actual rate where you submit all calculations for MOT, fuel, and insurance costs. Find out more about getting a business car lease as a sole trader here. 

If your car is used for personal use, this can get a little complicated though as you can only claim for the business use of your car. We’ve got some more information on how to expense for items that are used for both work and personal use later on in this article.

What expenses can’t I claim for as a sole trader?

Because an allowable expense is something entirely for business purposes, you can’t claim for anything used for personal reasons. If something is used for both work and business, you can claim part of this expense back but not all of it. Read the next section to find out more about this process. 

Other expenses that you cannot claim for include: 

Parking fines or speeding tickets

You can claim for the running of your car, but nothing anything that you’ve personally done wrong. 

Everyday clothes and workwear

Having a nice new suit will make you look the part and secure those all-important first impressions. But these clothes need to be paid for by yourselves unless they are explicitly classed as PPE or required uniform. 

Entertaining clients/guests

We’ve all seen the moment in a TV show where a fancy lunch is paid for by a business as an expense. And although there are cases where you can claim this back, I’m afraid it’s not true for sole traders. You’re not allowed any expense claims for entertaining guests or clients, so if you want to impress, that one is on your wallet. 

If you’re ever unsure of what you can or can’t claim, we’d recommend talking to an accountant for more help. If you don’t have one yet, find the perfect match online with our reviews of the best online accountants.  

What happens if I use something for both work and personal use? 

Not every sole trader will have a dedicated office or work phone. If you’re just starting out, you might be one of the thousands of people who run your business from your own home. When it comes to allowable expenses, this doesn’t mean you can just write off all bills and rent. Instead, you’ll be able to claim a proportion of the costs that are dedicated to business use. 

For example, if you can record how many calls on your phone bill are for business use, you can claim for those particular calls back while paying the remaining bill yourself. You can also claim for a fraction of your: 

  • Heating and electricity bills;
  • Council Tax;
  • Mortgage interest or rent;
  • Internet and telephone use.

Depending on how much of your home time is spent on business. In some cases, you can also use the number of rooms if you have a dedicated office set up inside your home. 

For example, let’s say you live in a 4 bedroomed house with one room set up as your office. 

This means ¼ of the rooms are for business use, allowing you to claim for ¼ of all household bills. So if your yearly internet usage is £400, you could get £100 back.

To help you calculate this, HMRC has a simplified expenses tool to remove all of that hard maths work. 

How do I claim for my allowable expenses as a sole trader?

The right time to claim your allowable expenses is when filling out your annual self-assessment tax return.

Sole traders will claim for allowable expenses when they fill out their annual self-assessment tax return. As with any return, you need to ensure that the information you have provided is accurate, correct, and on time, otherwise, you could be faced with some hefty fines or penalties. 

For expenses you want to claim back, make sure that you keep a record of them and their receipts to help fill in your tax return when it’s due. We’d also recommend getting the help of an accountant here to make sure all the information is spot-on. 

Do I need an accountant to claim for my expenses? 

No, you don’t need an accountant to submit your expenses and your tax returns. As a sole trader, you can take care of your entire financials by yourself and save yourself the extra bill. 

If you want to take care of your accounts by yourself, we’d recommend taking a look at choosing accounting software to make this a lot easier. To help make this choice an easy one, we’ve picked out some of the best accounting software for sole traders here. 

Although yes, you technically can claim for these expenses by yourself, our professional recommendation is to make sure that you have an accountant on hand to check your books and ensure it’s alright. This is especially important for making sure you’ve not missed any expenses you could be entitled to.

What expenses can a sole trader claim? A summary

Sole traders can claim a variety of expenses, including travel costs, equipment, training, and even utility or rent costs, provided that it’s for business use. 

If something is used for both home and business, such as when a business is being run from home, then sole traders will be able to claim back a percentage of these costs based on how much is for business use. 

These costs are claimed when sole traders fill in their annual self-assessment tax return and can provide much-needed relief to keep your business up and running in its best form. To make sure that you’re claiming for the right items, and to find any expenses you didn’t know you could claim for, we’d always recommend speaking to an accountant to help complete your returns.
