You can spend hundreds travelling for work and still receive no tax deduction. The receipt may be genuine and entirely work-related. Yet HMRC can reject the claim because of where you travelled or why the journey started.
That is the Travel and Subsistence trap many self-employed people miss. A cost can feel obviously business-related without meeting HMRC’s tax rules. Regular client visits, lunches, hotels, and mileage can all produce unexpected problems.
The real question is therefore not whether the cost relates to work, but whether it meets HMRC’s business expense rules. Getting that distinction wrong can increase taxable profits and your final tax bill.
Key Takeaways
- Ordinary travel between home and a regular workplace is normally not deductible.
- Travel between genuine business locations can usually qualify.
- Ordinary meals remain private, even when work requires eating away from home.
- Necessary hotels and meals can qualify during certain business journeys.
The Core HMRC Rule
For self-employed taxpayers, HMRC starts with the “wholly and exclusively” test. The expense must serve the trade and must not contain an inseparable private purpose. Travel receives particular attention because journeys often begin at home and can therefore involve both business and personal considerations.

This means a journey can be necessary to earn income without automatically becoming tax-deductible. Someone may need to travel somewhere every day to perform their trade. That does not remove the private element. HMRC generally regards travel between home and a regular workplace as ordinary commuting.

When Travel Can Qualify
Travel between genuine business locations will usually have a stronger case for deduction. For example, travelling from one client to another during the day normally has a clear business purpose. Journeys to suppliers, meetings, temporary jobs, and changing customer locations may also qualify.
HMRC lists costs such as fares, parking, hotels, and vehicle expenses as possible allowable travel costs. However, the underlying journey must qualify first.
Typical examples include:
• Travelling between two customers during the working day
• Visiting a supplier to discuss stock or services
• Travelling to an occasional business meeting
• Attending changing sites as part of an itinerant trade
• Travelling to a qualifying overnight business event
Accurate bookkeeping services can help because records should explain why the journey took place.

The Home-to-Work Trap
Home-to-work travel causes more problems than many sole traders expect. Being self-employed does not remove the concept of commuting. Regular travel between home and an established business location will normally remain private.
Consider a shop owner who travels from home to the same shop every morning. The business cannot operate without the owner attending, but that does not make the journey deductible. HMRC views the choice of where to live as part of the private purpose.
(Source: HMRC Business Income Manual: travel between home and work)
HMRC may consider your wider working pattern. This includes how often you attend the same place and where you conduct the trade. It may also consider whether the journey resembles ordinary commuting.
The Regular Client Trap
A freelancer may describe every visit to a customer as a business journey. However, frequent and predictable attendance at the same location can weaken the claim.
(Source: HMRC Business Income Manual: subcontractors and travelling expenses)
For example, a consultant who attends one client’s office four days each week may struggle to deduct every journey. The location may form part of the normal business pattern, even if the contract is temporary.
This is where diaries, contracts, invoices, and working arrangements become important. Proper Self Assessment tax return support can help review recurring travel before expenses enter the return.
Itinerant Businesses Are Different
Some trades are naturally mobile. Builders, electricians, repairers, photographers, and other service providers may work across changing locations as part of their ordinary business.
HMRC discusses this principle through Horton v Young. The taxpayer worked across changing sites rather than one established workplace, which supported the travel deduction.
(Source: HMRC Business Income Manual)
However, working at several addresses does not automatically make a business itinerant. One location may still become sufficiently regular or predictable to create a problem.
Why Ordinary Meals Usually Fail
Subsistence is another area where reasonable-looking claims often fail. Many people assume lunch becomes deductible because work requires them to eat away from home.
HMRC normally treats ordinary food and drink as personal living costs because everyone needs food regardless of work.
The case of Caillebotte v Quinn illustrates this principle. A self-employed carpenter bought meals while working away, but the expenditure remained private. (HMRC Business Income Manual)
You also cannot normally claim only the extra cost. If lunch costs £15 outside but £5 at home, the £10 difference does not automatically qualify.
Hotels and Overnight Trips
Hotel and subsistence costs can qualify when genuine business travel requires an overnight stay. HMRC allows reasonable accommodation and related subsistence where the underlying journey qualifies.
For example, a sole trader may travel from London to Manchester for a two-day client assignment. The hotel and reasonable meal costs may qualify. However, a weekend extension would remain private.
The same principle applies overseas. Business travel costs may qualify, but family costs, sightseeing, and holiday extensions remain private. Keep invoices, bookings, and evidence showing the business purpose.

Mileage Rates for 2026/27
Self-employed taxpayers can use simplified vehicle expenses instead of calculating actual running costs for eligible vehicles.
For 2026/27, cars and goods vehicles qualify for 55p per mile on the first 10,000 business miles. The rate falls to 25p per mile afterwards. Motorcycles remain at 24p per business mile. (GOV.UK simplified vehicle expenses)
These rates only calculate the value of qualifying business mileage. They do not turn private commuting into an allowable journey.
Simplified mileage or actual costs?
You can instead calculate the business proportion of actual vehicle costs where the rules allow. That may include fuel, insurance, servicing, and other running costs.
However, you cannot normally switch freely between methods for the same vehicle. HMRC restricts simplified mileage where capital allowances have already been claimed.
(Source: GOV.UK simplified vehicle expenses)
The best approach depends on your mileage, vehicle costs, and record-keeping. Tax planning advice can help compare the options.
Records HMRC Expects
A receipt proves that money was spent, but it does not establish the business purpose. Your travel records should therefore show:
• the date of the journey;
• the starting point and destination;
• the business reason for travelling;
• the client, job, or meeting involved;
• the number of business miles;
• the amount claimed.
Train tickets, hotel invoices, parking receipts, and appointment evidence should support the entry. Keeping this information consistently throughout the year makes any later review much easier.
What Happens If HMRC Disagrees?
HMRC can remove expenses that fail the business purpose test. This increases taxable profits and may increase Income Tax and National Insurance. Interest may also arise where the adjustment creates overdue tax.
Penalties can apply if an inaccurate return understates tax. HMRC considers the taxpayer’s behaviour when deciding the appropriate penalty.
For standard onshore inaccuracies:
• Careless errors can attract penalties up to 30% of potential lost revenue;
• Deliberate inaccuracies can reach 70%;
• Deliberate and concealed inaccuracies can reach 100%.
The final penalty depends on behaviour, disclosure, and the circumstances. (HMRC Compliance Handbook)
Proper records and a careful review can help demonstrate reasonable care.
Common Mistakes to Avoid
Several errors appear regularly in Travel and Subsistence claims:
• claiming every journey simply because work caused it;
• treating regular client travel as automatically allowable;
• applying the employee 24-month rule to sole traders;
• claiming ordinary lunches, coffees, and snacks;
• using mileage rates for journeys that are actually commuting;
• keeping receipts without recording the business purpose;
• failing to separate private extensions from business trips.
Good sole trader accounts should distinguish commuting from qualifying business travel.
Before You Claim
Before putting Travel and Subsistence through your accounts, ask a few practical questions:
• Where does the business genuinely operate?
• Is the destination part of your normal working pattern?
• How frequently do you attend the same location?
• Does the journey contain any private purpose?
• Is the business genuinely itinerant?
• Does the meal fall within a recognised exception?
• Was the overnight stay commercially necessary?
• Can your records explain the journey clearly?
If several answers remain unclear, review the expense before filing. Correcting it now is easier than dealing with an HMRC enquiry.
Getting Travel Expenses Right
Travel and Subsistence claims depend on more than proving that you spent money while working. HMRC considers the destination, working pattern, journey purpose, and any private element.
Ordinary commuting and everyday meals create the greatest risk. Genuine itinerant travel and necessary overnight trips can qualify when the conditions are met.
Before filing, review recurring journeys and make sure your records support each claim. If the treatment is unclear, Self Assessment tax return support can help ensure the correct expenses are claimed before submission.
