HMRC volunteer expenses: How to reimburse your volunteers in an HMRC-friendly way

When it comes to HMRC volunteer expenses the rules are a little bit different than usual.

In some ways, it's more lenient as the government wants everyone to be in a position to volunteer. But volunteer expenses and volunteer payments aren’t something you should mess around with.

You need to understand the difference between a volunteer and an employee to avoid a nasty surprise when the tax man comes around.

Let's break down exactly what constitutes a volunteer, why they should be reimbursed and how you can reimburse them. 

When do volunteer expenses qualify for tax-free claims?

If you have people volunteering their time, effort and skills for your organisation, it only makes sense that you want to take care of them by paying for their expenses.

And so long as a volunteer expense is reasonable and necessary for their work then it qualifies as a tax-free expense. In fact volunteer expenses are in some ways more lenient than employee expenses.

Some common volunteer payments include:

  • Drinks and meals taken whilst volunteering 
  • Travel to, from and during volunteering
  • Protective clothing or equipment necessary to volunteering
  • Care of any dependents the volunteer might have, like children or an elderly relative
  • Out-of-pocket expenses like the cost of phone calls, stationary or postage necessary for the volunteer’s work

If you want to offer a volunteer any other kind of reimbursement to say thank you for their time, you’ll have to be careful you aren’t giving them taxable income or turning them into an employee.

What’s the difference between a volunteer and an employee?

If a volunteer develops a ‘contract of service’ with an organisation then they are technically an employee.

It’s worth mentioning a contract doesn’t need to be written down, it can be verbally agreed upon or even happen as a result of a particular set of working circumstances.

Some of the signals you may have developed a ‘contract of service’ with a volunteer include:

  • Telling them how, when and where to work
  • Not allowing someone else to perform the work
  • Giving a volunteer a set number of hours they have to work
  • Giving a volunteer a regular wage, payment or benefit for the work
  • Promising a volunteer future or reoccurring work

If your working relationship with a volunteer includes the majority of the signals of a ‘contract of service’, then you might be a bit too close to employment for comfort.

The problem with a volunteer becoming an employee is they’d have to be taxed for national insurance and income tax and have different employment rights.

Not to mention this tax can be backdated if HMRC deems a volunteer always has been an employee. Oops.

If you’re in this position consider analysing whether the volunteer still retains the freedom to leave without notice or turn down work. These are both signs that point away from employment.

If in doubt you can even contact HRMC to get their opinion on your volunteer’s status. 

Why should volunteer expenses be reimbursed?

Aside from the fact that it’s thoughtful and encouraging, reimbursing your volunteers for their expenses makes volunteering more accessible.

Ultimately covering volunteer expenses could increase your pool of volunteers, not to mention their morale and work ethic. Covering their expense can also save you money if its a tax-deductible expense. So reimbursing volunteer expenses truly is a win-win.

How can volunteer expenses be reimbursed?

You should only be reimbursing volunteers’ expenses for the exact amount they are paid for the expense, not offering a flat rate.

A flat rate would look like you offering a volunteer £15 a day to cover their travel and any meals taken. The problem is that £15 could be a fair bit more than what the volunteer actually paid for their cheese and ham meal deal and all-day bus pass.

That extra £5.60 the volunteer didn’t need could be regarded by HMRC as income.

This is where you might fall into dodgy volunteer-come-employee territory. It also suggests more of a ‘contract of service’ between a company and a volunteer.

There’ve been cases where HMRC reviewed volunteer payments and decided they’re earnings. As such, they’ve then demanded years of national insurance and income tax.

To avoid this situation we recommend you:

  • Have an expense policy that sets your volunteer allowance, limits and expectations
  • Create an easy-to-use expense form for volunteers
  • Have a system for recording and reimbursing volunteer expenses
  • Always reimburse the exact amount a volunteer has spent

This means volunteers have to provide proof of purchase and how much it cost for every expense. Let’s take a look at how that might look in various expense areas:


You can offer volunteers travel to a place of volunteering as a reimbursable expense that’s also tax deductible for you! There are a few ways a volunteer could claim reimbursement.

They could:

  • Print the details of their Oyster or pre-paid travel card in a way that demonstrates how much they used for volunteering. (Fun fact: our Pleo cards auto-generate a ticket for your TfL journey the second you tap on your card on the reader.) 
  • Keep receipts or tickets for specific bus or train journeys
  • Keep receipts for a season ticket (so long as the season ticket is cheaper than the cost of individual or return tickets for the volunteering period)

If the volunteer has a disability or needs to travel particularly early or late, then you can reimburse a taxi for them. But the cost of the taxi is capped at four times the rate that journey would cost as a regular driving expense.

The volunteer would need to provide a taxi or Uber receipt to prove exactly how much they spent as well.

Speaking of driving expenses, if the volunteer drives you’ll have to follow HMRC driving expenses guidelines. To find out all HMRC’s scale rates on mileage have a look at our blog on HMRC’s mileage rates for 2022

Phone and internet

The volunteer would have to buy an internet connection wholly and exclusively for their volunteer work for it to qualify as a reimbursable expense.

They can then provide their internet bill as proof of the exact cost of their expense.

However, if the volunteer already has an internet connection, or uses the internet connection for personal use then they cannot claim any kind of volunteer allowance. As it’s not an extra financial burden for them to use their own internet for volunteer work.

It’s the same with a telephone bill. So long as using the telephone bill for their volunteer work doesn’t incur any additional expense then there is nothing they can be reimbursed for.

If the volunteer was paying for a telephone contract wholly and exclusively for the volunteering work, then that’s something to claim for. They could also claim if they had bought extra minutes or incurred extra expenses by using their phone more than usual. 

They would have to prove the extra cost was wholly and exclusively for volunteering work, not their personal telephone usage.

Meals taken

A good rule of thumb is that meals and refreshments qualify as a volunteer expense if someone’s worked four hours or more within one day. The spending has to be reasonable, so no fine wine or five-course meals, unfortunately.

Protective clothing or uniform

When it comes to protective clothing you’re obligated to provide your volunteers with PPE (personal protective equipment) or reimburse them for buying their own.

Uniform is also an acceptable volunteer expense, so long as it satisfies HMRC’s super special guidelines on what constitutes a uniform.

So an all-black polo neck from M&S that you’ll probably wear again is unlikely to qualify.

Whereas a specific hospital tunic that’s a recognisable uniform would be considered a volunteer expense by HMRC. In that case, you could either ask your volunteer to buy it and provide you with the receipt for reimbursement, or you could buy it for them directly depending on your expense policy.


If an individual has to arrange child care or care for adult dependents to volunteer then you can choose to reimburse them for these costs as well.

So long as the cost of care is reasonable, and in line with average care costs for the area, then HMRC considers it an appropriate volunteer expense without any national insurance or income tax needed.


Be aware it’s trickier to work out how to claim informal care arrangements with family or friends than it is to claim from formal care agencies. You are within your rights as a company to only cover formal care arrangements, or even only offer reimbursement if a volunteer uses a particular care agency.

How can you keep records of volunteer expenses?

The easiest way to keep track of volunteer expenses is to use an automated spending solution, like Pleo. But we know not every business is in a position to make that leap just yet.

So the next best way to keep a record of volunteer expenses is to use expense claim forms for volunteers to fill in and return alongside their receipts. Bonus points if you share your expense policy with them beforehand so they understand what their volunteer allowance and scale rates are.

At a basic level, an expense claim form should ask:

  • How much did you spend?
  • When did you spend it?
  • What did you spend it on?
  • What shift were you working at the time?

Depending on the nature of your volunteer’s work you may want to create more specialist forms if the majority of the claims are for a certain thing. Like if your volunteers do a lot of driving then you could create an expense form that has a column for mileage.

You can then record all these details in monthly volunteer expense spreadsheets, and keep the forms and receipts in reserve. It’s all about creating a paper trail so HMRC can see what you’ve done is by the book.

On that note, we’d only recommend paying volunteer expenses by cheque or BACS via online banking rather than paying in cash, so it’s crystal clear exactly what you’re paying your volunteers.

Our top three practical considerations for volunteer expenses 

When it comes to volunteer expenses you must understand tax regulations, so you don’t cause financial problems down the line for both the organisation and the individual who volunteered.

Even if you are a charitable organisation that’s off the hook for some forms of tax, you can still end up in a sticky situation when it comes to volunteer expenses if you don’t fully understand the rules. 

So make sure you read our top three practical considerations. 

(Can you hear the serious tone in our voice?) 👇

1. What are the tax implications around gifts to volunteers?

So long as you’re only reimbursing the exact amount an expense has cost a volunteer, and that amount is reasonable, then you’re free from paying income tax or national insurance.

But if you’re making a payment to a volunteer that includes: 

  • A cash sum
  • A large gift
  • A benefit in kind, like using your facilities for free
  • An honorarium, a token amount of money as thanks for their services

These could be viewed as a reward for the volunteer's work and could classify as taxable income under HMRC’s guidelines.  

Can volunteers be paid? 

The thing to bear in mind is as soon as a volunteer is paid regularly or starts expecting payment, it begins to count as earnings and is taxable. Whereas a traditional honorarium is meant to be unexpected, a one-off and a token expression of thanks.

Even an honorarium as a form of volunteer payment can be taxable, so in these situations, it’s best to review HMRC’s guidelines and even get in touch with them to clarify your unique situation. 

2. Are there tax implications for paying volunteers more than their exact expenses?

If you cover a volunteer’s expenses above and beyond what they actually spend, then this can be classed as payment for their services which will have national insurance and income tax implications.

Not only might you have to pay or backdate those forms of tax, but the rules on tax-deductible expenses are more rigorous for employees than volunteers.

Remember: if HMRC decides your volunteer is actually an employee and you’ve therefore not paid enough tax they can backdate that tax claim for up to 20 years if they suspect deliberate evasion, six years for carelessness and four years for mistakes.

3. What’s the difference between a volunteer classed as an employee and an office holder?

An office holder is a person who’s been appointed to a position or role of authority within a company but does not have a contract or receive regular payment. Typical office holder roles might be a company director, club treasurer or trustee.

Even if that particular person leaves the role, the role will continue to exist and need to be filled for the organisation to continue.

That might sound suspiciously like an employee, but an office holder doesn’t necessarily have the same employee rights, like:

  • The National Minimum Wage
  • Working Time Regulations
  • A contract
  • Regular payment
  • Pension Obligations

Because the role of an office holder is still quite taxing, and they don’t receive standard employee rights, they are often given honorariums or gifts to say thanks for their work. As such office holders have to pay income tax and national insurance, even if the amount is very small.

Someone can also be an office holder and an employee at the same time, so it’s worth checking out HMRC’s Employment Income Manual on this topic if you find yourself in a sticky office-holder-employee-tax scenario.
