Don’t get caught out by online adverts and tax refund companies who offer to make work expense claims for you so they can claim a commission. If it turns out you aren’t eligible to claim, you’re still responsible for any claims made on your behalf.
We’ll help you understand how to check if you’re eligible to claim, what you can and can’t claim for, and how to claim with HMRC directly. If you’re eligible, you’ll keep 100% of any money that you’re owed.

Check what you can and can’t claim for
If you meet the eligibility criteria, you might be able to claim tax relief for the following types of work expenses:
- Working from home
- Uniforms, work clothing and tools
- Vehicles you use for work
- Professional fees and subscriptions
- Travel, subsistence, and overnight expenses
- Buying other equipment
But you will need to double check you’re eligible first so that you don’t get caught out. You can find more information on what you can and can’t claim for and how to claim tax relief for your job expenses on GOV.UK.
It doesn’t take long to check and could save you a lot of time and money later on – so always check your eligibility before you make a claim.
Even if you choose to use a tax refund company or agent, make sure your claims are valid, as you’ll have to repay any incorrect claims to HMRC later. Making incorrect claims may also result in additional action by HMRC.
Top reasons for invalid work expense claims
There are a number of things you cannot claim for. For example, you can’t claim for any expenses that your employer has already reimbursed.
Take a look at the most common reasons for invalid expense claims (click to expand):
Travel and overnight expenses
You cannot claim:
- travelling or commuting to and from your normal place of work
- lunch costs when you are travelling to your normal workplace. You can only claim expenses for food and drink when travelling to a temporary place of work
- food you bring from home when travelling to a temporary workplace. You can only claim the cost of food you paid for during your time away
Working from home
You cannot claim:
- work from home costs when you have an office base but choose not to work there. If your employment contract lets you work from home some or all of the time, for example as part of flexible working arrangements, then you won’t be eligible for this relief
- eligibility for the ‘working from home’ relief changed after the end of the COVID-19 pandemic. Just because you were eligible to claim back then don’t assume you’re still eligible
Uniform, work clothing and tools
You cannot claim:
- expenses for uniform, work clothing or tools that have already been provided by an employer. This includes choosing to purchase ‘better quality’ alternatives to those provided by your employer
- uniform washing costs when your employer has a laundry facility that you choose not to use, such as by washing your uniform at home instead
- workwear that doesn’t include a visible logo. For example, if your employer advises you to wear all black clothing this is not an eligible expense
Professional fees and subscriptions
You cannot claim:
- union fees – unlike certain professional membership fees, these aren’t an allowable expense

Recognise the signs of bad advice
If someone promises easy money and it sounds too good to be true, it probably is.
Handing over your personal information could mean you end up having to pay back the full amount of any invalid claim made on your behalf, including any commission an agent has already taken.
Before using a tax refund company or tax agent for rebates, take your time and do some research. If you choose to use an agent to represent you, you can read more information on GOV.UK about how to choose a tax agent.

Check reviews from other customers
Search online for other customers’ feedback on their experience.
It’s a good idea to search to see if they are accredited by a professional body such as the Institute of Chartered Accountants in England and Wales or Chartered Institute of Taxation.
Read the small print
Even if an agent looks legitimate, always read any terms and conditions.
If you are asked to sign a disclaimer, read it carefully, and make sure you fully understand any fees the agent will charge.
Remember, you are still responsible for any claims made on your behalf, even if you choose to use a tax refund company or tax agent.
When you sign an agreement with an agent, you might be asking them to be your legal representative for all your tax affairs – even long after the claim has been made.
Watch out for red warning flags
Most importantly, never sign a blank tax return for a tax agent to fill in, and always review a return before approving it.
An agent should always ask for receipts and should never ask you to share your Government Gateway ID.
HMRC will never endorse an agent.
Claim directly with HMRC
It’s fast, free and simple to claim work expenses with us directly via GOV.UK.
You won’t have to pay any agent fees or commission if you do it yourself.
For most expense claims, you will need to provide evidence to support your claim.
The evidence will vary depending on the expense type you are claiming. It’s quick and easy to check what evidence is required using our eligibility checker page, and you can submit your claim and evidence online or through the post.
Five things to keep in mind before claiming
✔ Have you got evidence to back up your expense claim? Customers who want to claim work expenses may be asked to provide supporting evidence to prove their eligibility before we progress the claim.
✔ Tax relief on expenses won’t necessarily lead to a repayment. Some expenses are automatically coded through to the following year – check your tax code is still correct.
✔ Expenses must be completely work-related and necessary for you to do your job. You can’t claim for any expenses that your employer has already reimbursed.
✔ If you had an eligible claim in a previous job but the terms are different in a new job, then you may have incorrect items in your tax code.
✔ If your expenses are under £2,500 and you’re completing Self Assessment, you can save time by using our quick digital claim service – check you’re eligible via our Eligibility Checker
Personal stories
This story is hypothetical and created for illustrative purposes but is based on real experiences. Any similarities to an individual are purely coincidental.

Mike is a healthcare worker. A colleague suggests they use a uniform expense refund company to claim some money back from HMRC.
On the company’s website, he uses a refund calculator that indicates he can claim £200 back from HMRC in work-related expenses.
The company later takes £80 of fees from the £200 refund paid by HMRC. Although surprised by the sizable fee, Mike’s still pleased about the extra cash.
A year later, HMRC informs him he wasn’t eligible for the expenses claimed on his behalf – and that he must pay back the full £200, plus interest.

Shocked at this, Mike realises he can’t reclaim the fee from the company because he signed a ‘third-party agreement’.
Ultimately, he is responsible for his own tax affairs, even though he used a company to claim on his behalf.
After speaking to HMRC, Mike realises there were some red flags that the company just wanted to bag a commission, without checking if he was eligible to make a claim. For a start, the company never asked him to show any receipts as evidence of work costs. They also never confirmed what expenses they were claiming for on his behalf.
Mike wishes he’d paid closer attention so he didn’t get caught out by bad tax advice.
Mike now reminds colleagues to always check they’re eligible for work-related expenses with HMRC online before claiming anything, even if they use a tax refund company.

Sam works as a marketing executive for a hospitality company.
One evening while on social media, Sam noticed an advert that said she could be entitled to claim up to £1,500 in travel, subsistence, and overnight expenses. The advert was from a company that claimed they could help workers reclaim money for a variety of work-related expenses.
The next day, after mentioning the advert to her colleague, Tara, Sam was quickly warned off contacting the company. Tara had recalled seeing an advert for HMRC’s Don’t get caught out (DGCO) campaign and remembered that, if you’re an employee, most expenses will be reimbursed through your employer.

Following this advice, Sam visited GOV.UK and was able to confirm what Tara had told her, meaning she had dodged a potentially expensive bullet.
She now understands that while there are legitimate tax reliefs available to employees, these are usually far less in value than what was claimed by the company behind the advert, and any claims can be made directly through HMRC’s official channels.
