HMRC travel expenses: guidelines for business travel & tax in the UK
Sophie Johnson

Published on January 16, 2024

Corporate travel has developed a love/hate reputation. For employees, it's exciting to get out of the office and change up the routine. For employers, travel is a key driver of growth. Meeting prospects and clients in person is still incredibly effective, even if feels a little old fashioned.

So there's plenty to love.

And yet, managing travel - and especially travel expenses - is nobody's idea of a good time. Particularly when the rules and regulations from HMRC aren't clear to everyone.

So to help, we've put together this guide to travel expenses for UK businesses. Once you understand what HMRC expects (and therefore what you need to do), managing travel doesn't feel quite so painful.

Disclaimer: This is not legal, accounting, or tax advice - it's simply a guide. If you need help, check with your accountant or contact HMRC directly.

Now, let's start with the obvious question.

What are travel expenses?

As the name suggests, travel expenses are company expenses incurred while travelling. These include transport costs, meals, and vehicle mileage, among others.

And as with all legitimate business expenses, companies may be able to claim tax relief on these costs. If it meets all of the correct requirements, business travel is normally free from tax.

So both for companies and individual employees, it makes fiscal sense to track and claim tax relief on business trips.

HMRC travel expenses: the basics

HMRC may provide tax relief if costs fall into the following categories:

  • Public transport costs

  • Hotel accommodation if you have to stay overnight

  • Food and drink

  • Congestion charges and tolls

  • Parking fees

  • Business phone calls and printing costs

  • Mileage

As long as these occur during business travel, the company should be able to claim relief.

So what counts as business travel?

LeeP Financial shares this handy reference guide for company managers and employees:

Deductible Non-deductible
Travel other than commute to and from permanent workplace. Normal commute to and from permanent workplace.
Food and drink on work journeys outside normal commute - actual or day rates. Parking fines, speeding tickets and other penalties.
Overnight accommodation on work journeys. Travel costs not exclusively for work e.g. top up of travel card also used for non-work.
Dinner and breakfast when staying overnight.  

Part of what makes all this tricky is the overlap between private and business travel. It’s not always clear exactly what counts as each.

Private vs business travel


The distinction between these two forms of travel is a common cause of confusion. It’s simply not always clear cut whether a trip is entirely for personal or business reasons.

There can easily be portions of a business trip that look like personal travel, and vice versa.

According to HMRC, only two types of travel qualify as “business” trips:

  1. Journeys employees make in the performance of their duties (where travel is part of their duties)

  2. Journeys to or from a place they have to attend in the performance of their duties (travel to a place where attendance is in the performance of the duties). This usually means visiting a temporary workplace or site outside of their regular commute.

So if travelling is your job, or if you have to visit a specific location in order to do your job, this is business travel.

Crucially, “ordinary commuting” is explicitly not counted as business travel.

Travel expenses for employers

Employers are required to report all travel expenses paid to employees during the year. There are some exceptions to this rule, especially where you’re paying HMRC’s advisory rates, or where you’ve applied for a specific exemption.

A few things to keep in mind:

  • Some expenses like fuel and meals have fixed rates. If you reimburse employees at higher rates, these become earnings (like salary), and are subject to PAYE and National Insurance.

  • If you provide extras like transport to employees for private travel, this becomes a benefit and is subject to National Insurance as well.

  • To be deductible, expenses need to be “wholly and exclusively incurred” for the purposes of running the business or generating more business.

  • But this doesn’t mean every aspect of a trip needs to be related to business. Bleisure trips are permissible, but only the business aspects of that trip can be deducted.

This should be common sense for most businesses. And as long as good records are kept and there’s a smooth process in place, you shouldn’t have much trouble managing travel.

Travel guidelines for employees

If you travel for work, incur expenses as a result, and these expenses are not reimbursed by your company, you may be able to claim tax back from the government.

To claim tax back for any kind of work expense (including travel), a few conditions must be met:

  • You personally pay for a necessary work cost

  • This cost is only necessary for work

  • Your employer doesn’t pay you back

  • Your employer doesn’t offer you a suitable alternative

And of course, you also have to pay tax, since this is a tax break.

Claiming travel expenses from home to work

We’ve seen that travel expenses can be claimed if you’re travelling to a place of work. But equally, you can’t claim if your travel counts as commuting. So what’s the core difference?

Permanent vs temporary worplaces

Commuting is the regular travel you make to a permanent workplace. Thus, if you want to claim tax back for work travel, these trips need to be to or from a temporary workplace.

In most cases, that’s going to be pretty simple. If you’re out on a sales call, going to a conference, or visiting another branch of the company, you’re not going to your permanent workplace.

Another little note: if your travel to a temporary workplace is not really any different from your regular commute (in time, distance, or costs), you can’t claim relief for this either. So if you're heading to a client just down the road, this is probably not going to count.

Common causes of confusion

Let’s look now at a few of the most common - and often most confusing - areas for mistakes.

Meals and subsistence rates

Not every single pound, dollar, or euro spent while travelling is going to be reimbursed. That would leave the door open to abuse - Michelin-starred meals and exorbitant bar tabs claimed as “business costs.”

To set clear rules and expectations, HMRC has provided a list of meal allowance rates for different cities and countries. These work like a per diem, standardised for all UK businesses. And they also include the cost of accommodation.

When reimbursing employees for meals, companies have a few options:

  1. Use the set amounts allowed by HMRC

  2. Negotiate another rate with HMRC, if the rates provided don’t meet the company’s needs

  3. Reimburse employees in full, no matter the cost

Note: If your business opts for the third choice, the amount reimbursed will only be tax-free up to amount allowed by HMRC. So you can reimburse at a higher rate if you choose, but you’ll have to pay tax on the difference.

Fuel rates

Alongside meals, HMRC has also standardised the amount companies can reimburse employees for fuel tax-free. This reflects the fact that every car has a different expectation of efficiency, and that fuel prices fluctuate.

Instead of trying to deal with this on a case-by-case basis, HMRC has assigned advisory fuel rates for company travel. These apply in two cases:

  1. When reimbursing employees for work travel done in company cars

  2. When employees need to repay the company for private travel in a work car

In either instance, advisory fuel rates tell companies and employees exactly how much they should expect to pay or receive per mile.

The 24-month rule

We already wrote a detailed explanation of HMRC’s 24-month rule. It’s a relatively simple test to help you figure out whether a workplace is temporary or permanent. If it’s permanent - as a result of meeting the 24-month rule - employees and companies cannot claim tax relief for travel expenses.

Two key conditions have to be met for the 24-month rule to apply:

  1. The employee must have spent or be likely to spend more than 40% of their working time at a workplace, AND;

  2. They must attend it or be likely to attend it over a period lasting more than 24 months.

So in short, if you spend more than 40% of your time in a single workplace over a 24-month period - that’s a permanent workplace.

There are always complications to these rules, so it’s worth reading that article linked above.

Employed, self-employed, both, or neither?

Naturally, there’s no one-size-fits-all rule for employee travel. Your tax rights and obligations depend on your employment status, among other things.

And - especially in the modern careers landscape - there are whole range of different circumstances that can complicate matter. These affect:

  • Agency staff billing out time to clients

  • Employees working through umbrella companies

  • Contractors working through a limited company for a larger company

  • “Personal Services Companies” (hairdressers, care workers, and labourers, among others) fall under the IR35 legislation and may have other obligations.

This isn’t the time or place to go into all of these circumstances in detail. This post from the Low Incomes Tax Reform Group does a great job of highlighting the differences.

But to clarify: in this post, we’re mainly speaking to companies and their full-time employees.

Best practices to manage travel expenses

As a bonus, here are a couple tips and best practices on handling travel expenses from around the web.


Contractor Calculator - Keep clear records

Contractor Calculator writes for contractors - obviously. But this advice is valuable whether you’re a sole practitioner or run a company of 10,000:

“Both limited company and umbrella company contractors must retain copies of receipts and tickets, and detailed mileage logs, so that they can prove the journey actually took place if investigated by HMRC.”

And of course, you’ll want those receipts if you have come up against a full on audit.

Spendesk - Automate as much as possible

Aside from misunderstood rules, the biggest issues with travel expenses normally relate to admin. Filing and processing every single expense claim by hand is a huge productivity killer.

When it comes to business travel, the more you can automate your expenses, the better.

This means looking for a good travel and spend management tool, like Spendesk. These let you automate processes, and also build in your company travel policy to keep everyone in line.

Work travel shouldn’t be a bore

For many employees, travelling for work is a great privilege. The chance to visit new cities, meet clients, and have new experiences is too good to pass up. They’re the lucky ones.

Too often, business travel gets bogged down in minutiae. The little things - expense reports and transport issues - can overshadow what should be a break from the norm. Which is a shame.

But with good planning, and better technology, corporate travel goes back to being a benefit. So find yourself a good travel management tool, get a smarter way to track expenses and store receipts, and stop sweating all of those little issues.
