Did you know HMRC has not increased the standard 45p tax-free mileage rate since 2011? Despite massive spikes in fuel costs and a completely different economic landscape, that figure remains firmly frozen in time -seemingly until now, with an oil war on the horizon. It is a frustrating reality for many limited company directors. However, missing out on claiming this relief entirely is an even bigger mistake.
We speak to small business owners every day who leave thousands of pounds on the table. You might feel anxious about making an error on your corporation tax return or triggering an unexpected HMRC compliance check. Those financial worries are completely valid. Taxation rules often feel like a maze designed to trip you up.
Understanding exactly what qualifies as a legitimate travel cost takes the stress out of your tax filings. It also helps you keep more hard-earned cash inside your business. This guide will break down the rules for UK limited company owners, providing you with clarity and confidence ahead of your next tax deadline.
Can I put travel as a business expense?
Yes, you absolutely can. HMRC allows you to claim travel costs, but they apply very strict definitions to what qualifies. The fundamental rule is that the journey must be made wholly and exclusively in the performance of your duties.
As a limited company director, you are legally classed as an employee of your own business. This means you must follow HMRC rules regarding ordinary commuting. Ordinary commuting refers to the journey you make between your home and your permanent workplace. HMRC will never let you claim tax relief for your daily commute.
To claim the cost of a journey, it must fall outside of your normal routine. Travelling to attend a client meeting, visiting a supplier, or heading to a one-off training course all count as allowable business journeys.

What travel counts as an allowable business expense?
You can claim travel costs when you visit a temporary workplace. A temporary workplace is a location you go to perform a specific task for a limited amount of time.
This brings us to one of the most important concepts for contractors and limited company owners: the 24-month rule.
What is the 24 month rule?
HMRC states that a workplace stops being temporary if you spend 40 per cent or more of your working time there over a period lasting more than 24 months. If you sign a 12-month contract to work at a client's office three days a week, that office is a temporary workplace. You can happily claim your travel costs. If your contract gets extended to 30 months, that office immediately becomes a permanent workplace. From the date you know about the extension, your travel costs become ordinary commuting and are no longer allowable.
Here is a simple breakdown of what you can and cannot claim:
| Deductible Business Travel | Non-Deductible Travel (Commuting) |
| Travel to a client site for a specific meeting | Your daily drive to your main office |
| Train fares to an industry conference | Travel from home to a site where you work full-time for 3 years |
| Parking fees and toll charges during a business trip | Parking fines or speeding tickets |
| Hotel accommodation for an overnight business trip | Normal commute costs, even if you work late or are on stand-by |
Can I write off travel as a business expense?
Yes, writing off travel expenses is a highly effective way to optimise your limited company finances. When you pay for a business journey out of your own pocket, your company can reimburse you for the exact cost.
The company then records this reimbursement as an allowable business expense. This process reduces your company's overall taxable profit. A lower taxable profit directly results in a smaller Corporation Tax bill.
This write-off also applies to subsistence expenses. Subsistence covers the food, drink, and accommodation you need while travelling for business.
For example, If you travel from London to Manchester to pitch a new client and need to stay the night, the company can pay for your hotel and your evening meal tax-free.
HMRC expects these costs to be reasonable. Booking a standard business hotel and a normal dinner is perfectly fine. Attempting to claim a luxury five-star suite and vintage champagne might catch the attention of an HMRC auditor. Always keep your receipts to prove the cost was genuinely incurred.
Can I claim 45p per mile from HMRC?
If you use your own personal car for business trips, you cannot claim for individual fuel receipts, MOTs, or repair bills. Instead, you claim tax relief using Approved Mileage Allowance Payments (AMAP). Don`t guess, calculate your business mileage here.
The AMAP system provides a flat rate designed to cover the cost of fuel, wear and tear, and insurance.
Here are the current HMRC approved mileage rates:
| Vehicle Type | First 10,000 business miles (per tax year) | Each business mile over 10,000 |
| Cars and vans | 45p | 25p |
| Motorcycles | 24p | 24p |
| Bicycles | 20p | 20p |
Your limited company can pay you 45p per mile for the first 10,000 business miles you drive in the tax year, completely tax-free. You do not have to report this on your personal Self Assessment tax return as long as you do not exceed the approved amount.
If your company pays you less than 45p per mile, you can claim mileage allowance relief for the unused balance. For instance, if you only reimburse yourself 25p per mile through the company, you can claim tax relief on the remaining 20p per mile directly from HMRC
To stay compliant, you must maintain a detailed mileage log. HMRC requires you to record the date of the journey, the reason for the trip, and the exact postcodes for your starting point and destination. A simple spreadsheet or a dedicated mileage tracking app will keep you perfectly organised.
Key Takeaways and TL;DR
- Commuting is not covered: Travel between your home and your regular permanent workplace is ordinary commuting and never qualifies for tax relief.
- The 24-month rule matters: You can claim travel to a temporary workplace, provided you spend less than 40 percent of your time there over a period of fewer than 24 months.
- Mileage rates simplify claims: Use the 45p per mile rate for the first 10,000 miles driven in your personal car for business. This covers fuel and running costs.
- Subsistence is allowable: Reasonable costs for meals and hotel stays during overnight business trips can be written off against your Corporation Tax.
- Keep meticulous records: Always log your business miles with start and end postcodes, and save digital copies of your train tickets, parking receipts, and hotel invoices.
