What Counts as a Business Journey?
Before we get into the details of claiming vehicle expenses for business, you need to understand what HMRC actually allows.
HMRC’s rule is that a journey must be made “wholly and exclusively” for business purposes to qualify. This means if the trip wouldn’t happen without your work, you can probably claim it.
- What you can claim: Travelling to a temporary workplace, visiting a client, going to the bank to handle business accounts, going to a training course related to your work, or picking up materials.
- What you cannot claim: Your normal daily commute. Getting from home to your usual, fixed place of work; that’s private travel in HMRC’s eyes. Yes, even if it feels like work. The distance travelled does not affect HMRC’s position; ordinary commuting remains non-allowable.
For claiming vehicle expenses for business, you must document the date, destination, distance travelled, and specific business purpose of every journey.
What Are the Two Methods for Claiming Vehicle Expenses for Business
Whether you’re claiming vehicle expenses self-employed or claiming vehicle expenses for business as a director, there are broadly two approaches.
Method 1: Simplified Expenses (Flat Rate Method)
This is the most common approach for claiming vehicle expenses for business because it requires the least amount of paperwork. You claim a flat, government-approved rate per business mile. And for that, you track your business miles throughout the year. At the end, you multiply your miles by the HMRC rate. That figure goes on your tax return as an allowable expense.
The mileage rate is designed to cover everything: fuel, insurance, servicing, road tax, MOT, wear and tear. So you do not have to claim those costs separately. The rate bundles them all in.
From 6 April 2025, HMRC increased the approved mileage rate for cars and vans from 45p to 55p per mile for the first 10,000 business miles. Here are the official HMRC mileage and fuel rates for 2026/27:
| Vehicle Type | First 10,000 Business Miles | Miles Over 10,000 |
| Cars and Vans | 55p per mile | 25p per mile |
| Motorcycles | 24p per mile | 24p per mile |
| Bicycles | 20p per mile | 20p per mile |
If you are claiming vehicle expenses self employed, this method saves hours of administrative work. You just keep a clean log of your trips, then multiply the miles by the rate and claim the deduction.
Note: If you use the simplified mileage method for a vehicle, you must continue using that method for that vehicle as long as you use it in the business. You can’t switch to actual costs partway through.
Method 2: Actual Vehicle Costs
With this method, instead of using mileage rates for claiming vehicle expenses for business, you claim the business proportion of actual vehicle costs. You divide your business miles by your total annual miles to determine the business percentage. You multiply this percentage by your total annual vehicle running costs.
If you use this method, you can also claim Capital Allowances on the original purchase price of the vehicle, which isn’t possible with Simplified Expenses
The downside is the admin. You need to keep all your receipts and calculate the business-use percentage carefully. Claiming vehicle expenses for business this way takes time. Lots of it.
You will need to add up absolutely everything:
- Fuel and oil
- Servicing, repairs, and MOTs
- Car insurance and breakdown cover
- Vehicle tax (more on this in a second)
Note: Standard employees using personal cars generally cannot use this method; they are restricted to HMRC mileage rates.
Can You Claim Vehicle Tax as a Business Expense?
Yes, you can claim vehicle tax (road tax) as a business expense. But your ability to do so depends entirely on which of the two claiming methods you use.
If you are using the Actual Costs Method, you can absolutely include your annual vehicle tax bill. Just remember to apply your business-use percentage to it. If you use the car 50% for work, you claim 50% of the tax. It is a very straightforward way of claiming vehicle expenses for business.
If you choose the Simplified Mileage Scheme, you cannot claim vehicle tax separately. This is because the rate already has vehicle tax included. Trying to claim both is a fast way to get flagged by HMRC for double-claiming.
How to Deduct Vehicle Expenses for Business Correctly
As discussed above, to deduct vehicle expenses for your business, you must choose between two main calculation methods: the Standard Mileage Rate or the Actual Expense Method.
And to deduct vehicle expenses correctly, you should avoid these common mistakes:
- Claiming commuting costs
- Claiming both mileage and fuel separately
- Missing business journeys
- Poor record keeping
- Not separating personal and business use
Because these errors can lead to unnecessary HMRC enquiries. Also, remember that regardless of which method you select, you can only deduct the business-use portion of your vehicle’s total operating costs. So, keeping clean records will make claiming vehicle expenses for business much safer.
Claiming Vehicle Expenses When Self-Employed
If you’re a sole trader or in a partnership, both methods above are available to you.
Most people find the mileage method easier. This is true especially when starting out. But the actual cost method can win if you drive a lot of miles above 10,000, or if your running costs are particularly high. Either way, claiming vehicle expenses for business helps lower your profit. And lower profit means less tax.
A few practical points for claiming motor vehicle expenses as a self-employed person:
- You claim vehicle expenses on your Self Assessment tax return, under “vehicle and travel costs”
- You need a mileage log to support any claim. This can be a spreadsheet, an app, or even a paper diary
- Keep records for at least five years after the Self Assessment deadline
- You cannot claim for an ordinary commute to a regular, fixed place of business. However, if you are self-employed and your home genuinely serves as your base of operations, journeys from home to visit clients or temporary work locations are allowable business expenses.
HMRC may request evidence of business journeys and vehicle costs for up to several years after a tax return is filed, so maintaining accurate records is essential. If they query your return, you’ll need to show the journeys, dates, and purposes.
What Are the Vehicle Expenses for a Limited Company
If you operate through a limited company, the game changes completely. The company is a separate legal entity. So if you’re a director, you need to handle things differently. You have two main routes for claiming for a business vehicle.
Option A: Use Your Personal Car
This is the most common setup for many small company directors. If a director or employee uses their own personal vehicle for business purposes, the company can reimburse them at a set flat rate. This is the easiest route for claiming vehicle expenses for business as an owner. The company then claims tax relief on these reimbursed amounts.
- Cars and vans: 55p per mile for the first 10,000 miles; 25p per mile thereafter.
- Motorcycles: 24p per mile.
- Bicycles: 20p per mile.
Option B: The Company Owns the Vehicle
If the company buys or leases the vehicle, it is legally a Company Car. The company can normally claim tax relief on allowable running costs and capital allowances where applicable. It can deduct all running costs from its business profits to reduce Corporation Tax.
However, if you use this company car for any personal trips, you trigger a benefit-in-kind (BIK) tax. Electric vehicles can use the same HMRC mileage rates when employees use their own vehicle for business journeys. Company-owned electric cars may also qualify for favourable capital allowances and lower Benefit-in-Kind tax rates. Thus, you will have to pay personal tax on this perk, and the company will pay National Insurance.
For electric cars, the BIK rates are still very low and highly tax-efficient. But for petrol and diesel cars, the tax bill can be incredibly high. You need to keep this in mind when claiming vehicle expenses for business.
How Do You Claim Personal Vehicle Expenses for a Business Safely?
If you want to stay on the safe side of an HMRC tax inspection, your record-keeping must be flawless. You cannot simply guess your mileage at the end of the tax year.
If you are looking at how to claim car expenses for business, you need a continuous travel log. Every time you make a business journey, note down:
- The date of the trip.
- The start and end locations (including postcodes).
- The exact business reason for the trip.
- The total number of miles driven.
Using a mileage tracking app on your phone will make this effortless. It tracks your routes via GPS and creates a clean spreadsheet that your accountant will love. As a result, claiming vehicle expenses for business becomes completely stress-free.
What Are the Common Vehicle Expense Claim Mistakes
A few mistakes come up again and again when people are claiming motor vehicle expenses for business. The first is claiming the commute from home to a permanent workplace. The second is using mileage and actual costs at the same time for the same vehicle. This is not normally allowed. The third is forgetting that private use must be removed from the claim.
Another common issue is not starting the mileage log early enough. By the time someone tries to rebuild a year’s worth of travel from memory, the figures are usually too rough. For how do you claim personal vehicle expenses for a business, the answer is simple: track every business journey as you go, then claim only that part. Don’t leave claiming vehicle expenses for business to guesswork.
The Bottom Line
Claiming vehicle expenses for business is one of the most straightforward ways to reduce your tax bill. And in 2026/27, it’s even more valuable. Thanks to the mileage rate rising from 45p to 55p per mile!
You have to know which method suits your situation. You should also make sure to keep proper records and avoid accidentally claiming for personal trips.
Get those basics right, and claiming vehicle expenses for business becomes a reliable part of your tax planning every year.
