VAT on business mileage, fuel and vehicle costs: what can you reclaim?

If you use a car, van or other vehicle for your business, it is easy to assume that every fuel receipt, mileage claim or repair bill can simply go into your VAT return. In reality, VAT on vehicle costs is one of those areas where small mistakes can quickly lead to overclaiming, missed claims or messy records.

The good news is that the rules are manageable once you separate the different costs. Business mileage, fuel, repairs, servicing, vehicle purchases and leasing are not all treated in the same way. What you can reclaim depends on how the vehicle is used, who owns it, whether there is any private use and whether you hold the right VAT evidence.

If you are VAT registered and want your claims checked before submission, working with a VAT return accountant can help you avoid guesswork and keep your returns accurate.

Why VAT on vehicle costs can feel confusing

Vehicle costs are tricky because most business owners use vehicles for more than one purpose. You might drive to client meetings, visit suppliers, collect stock or travel between jobs. But you might also use the same car for school runs, shopping or commuting.

HMRC looks closely at business use versus private use. The main point is simple: you can only reclaim VAT where the cost relates to your VAT-taxable business activity. If a cost is partly private, you either need to split it properly or use one of the accepted VAT methods.

This is why good records matter. If your mileage log, fuel receipts and bookkeeping do not match, it becomes harder to prove what you have claimed.

Can you reclaim VAT on business mileage?

You can reclaim VAT on business mileage, but not on the full mileage allowance.

For example, the approved mileage allowance for cars and vans from the 2026/27 tax year is 55p per mile for the first 10,000 business miles and 25p per mile after that. This mileage rate covers more than fuel. It also includes wear and tear, insurance, servicing and general running costs. VAT can only be reclaimed on the fuel element, not the full mileage rate.

So, if you or your employee uses a personal car for business journeys, you need to work out the fuel portion of the mileage and keep enough VAT fuel receipts to support the claim. You should also keep details of the journey, date, destination, reason for travel and number of business miles.

If you are a sole trader and your records are not yet organised, an accountant for sole trader can help you separate business travel from personal motoring before your VAT return or Self Assessment becomes stressful.

VAT on fuel: what are your options?

Fuel is where many VAT errors happen. If the vehicle is used only for business, you can usually reclaim all the VAT on fuel, provided you have valid VAT receipts.

If the vehicle is used for both business and private journeys, you normally have 3 options:

You can reclaim all the VAT on fuel and apply the correct fuel scale charge. This accounts for private use through your VAT return. The scale charge depends on the car’s CO2 emissions and the length of your VAT period.

You can reclaim only the VAT relating to business fuel. This means you need detailed mileage records showing business and private mileage, then you claim only the business proportion.

You can choose not to reclaim VAT on fuel at all. This can make sense where business mileage is low and the fuel scale charge would be higher than the VAT you would recover.

The right option depends on your mileage pattern. If you use vehicles regularly for client work, deliveries or site visits, proper VAT return filing services can help make sure you are using the most suitable method.

What about repairs, servicing and maintenance?

VAT on repairs and maintenance is usually more straightforward. If the vehicle is used for business and the business pays for the repair or servicing, you can usually reclaim the VAT, even if the vehicle also has some private use.

This can include repairs, servicing, replacement parts, MOT-related work and maintenance costs. The key point is that the cost must be paid by the business and the vehicle must be used for business purposes.

However, if you are a sole proprietor or partner and the vehicle is used only for private motoring, you cannot reclaim the VAT just because you have a VAT receipt.

You may also be able to reclaim VAT on business-related running costs such as off-street parking or fleet management charges. Parking fines, speeding fines and penalties are different and should not be treated as normal reclaimable VAT costs.

If you are unsure whether your records support the claim, VAT accountants services can help review the cost before it goes into your return.

Can you reclaim VAT when buying a car or van?

Buying a vehicle is not the same as paying for fuel or repairs.

For cars, VAT recovery is usually restricted unless the car is used only for business and is not available for private use. HMRC treats commuting between home and your normal workplace as private use, not business use. This means many ordinary business cars do not qualify for full VAT recovery.

Commercial vehicles, such as vans used for business, are often easier to deal with, but you still need to show that the purchase is for business use and that you have a valid VAT invoice.

If you lease a car, you can usually reclaim 50% of the VAT on the lease payments where there is private use. The remaining 50% is blocked to reflect private use. Different rules can apply for taxis, driving schools and self-drive hire vehicles.

Because vehicle purchases can involve larger amounts of VAT, it is worth asking vat accountants to check the position before you buy or lease.

VAT on electric vehicle charging

Electric vehicle charging is becoming more common for UK businesses, but the record-keeping still matters.

If your business pays for charging at work or at a public charging point, you can usually recover VAT on the business-use element. If you are a sole proprietor or partner charging an electric vehicle at home, you may also be able to reclaim the VAT linked to business use, but you need a sensible method for separating business and private charging.

Keep charging receipts, mileage records and evidence of how you calculated the business portion. This is especially important where one vehicle is used for both business and personal journeys.

Common VAT mistakes with mileage and vehicle costs

One common mistake is reclaiming VAT on the full mileage rate instead of just the fuel element. Another is claiming fuel VAT without enough receipts to support the amount claimed.

Some businesses also forget to apply the fuel scale charge when they reclaim all fuel VAT on a vehicle that has private use. Others treat normal commuting as business mileage, which can cause problems if HMRC reviews the records.

Another issue is poor bookkeeping. If your bank payments, receipts and mileage records are not clearly matched, you may underclaim or overclaim without realising. Using a certified QuickBooks accountant can help you set up clear categories for fuel, repairs, mileage, parking and vehicle finance costs.

How to make your vehicle VAT records easier

The best approach is to keep things simple and consistent. Record each business journey when it happens, rather than trying to rebuild mileage months later. Keep VAT receipts for fuel, repairs, servicing, parking and charging. Make sure receipts show the VAT details clearly.

You should also review your vehicle use regularly. A fuel method that worked last year may not be right this year if your business mileage has changed. If you have taken on staff, added another vehicle or started using electric charging, your VAT process may need updating.

Good records do not just help with VAT. They also make your accounts cleaner, support tax deductions and reduce the risk of questions later. If your vehicle costs affect both VAT and your year-end accounts, tax return accounting services can help keep everything aligned.

When should you ask for help?

You should ask for help if you are not sure whether a vehicle counts as business-only, if you use the same vehicle for private and business journeys, or if your mileage records are incomplete.

You should also get advice before reclaiming VAT on a vehicle purchase or lease, as the amounts can be significant. A small mistake on a high-value vehicle can create a much bigger issue than a missed fuel receipt.

FAQs

Can I claim VAT back on business mileage?

Yes, but only on the fuel element of the mileage claim, not the full mileage allowance. You need records showing the business miles travelled and enough VAT fuel receipts to support the VAT being reclaimed.

Can I reclaim VAT on fuel used for both business and private journeys?

Yes, but you need to choose the right method. You can reclaim all the VAT and apply the fuel scale charge, reclaim only the business-use portion using mileage records, or choose not to reclaim VAT on fuel at all.

Can I claim VAT on car repairs if the car is used privately too?

Usually, yes, if the vehicle is used for business and the business pays for the repair or maintenance. Private use does not automatically block VAT recovery on repairs, but the vehicle must have genuine business use.

Can I reclaim VAT when buying a business car?

Only in limited situations. You usually need to prove the car is used only for business and is not available for private use. Many business cars do not qualify because they are available for private journeys or commuting.

Do I need fuel receipts to claim VAT on mileage?

Yes. You should keep VAT fuel receipts to support the VAT element of mileage claims. Your mileage records should also show the date, journey, business purpose, miles travelled and rate used.
