VAT on Mileage: Can You Reclaim Fuel VAT in the UK?

"Can I claim VAT back on my fuel?" is one of the most common questions self-employed people ask. And the answer they usually get (from forums, Facebook groups, even some accountants) is wrong. Or at least incomplete.

The short version: if you use the simplified mileage allowance (45p/25p per mile), you cannot reclaim VAT on fuel separately. The mileage rate already includes a fuel element. But if you're VAT registered and use the actual cost method, you can reclaim the VAT on fuel, using HMRC's advisory fuel rates or your actual receipts.

These two approaches are mutually exclusive. You pick one. Mixing them is wrong, and it's the mistake most people make.

The two ways to claim vehicle expenses

Before getting to VAT, you need to understand the two methods HMRC offers for claiming vehicle expenses. If you've read the guide to HMRC mileage rates, this will be familiar.

Method 1: Simplified mileage (AMAP rates). You claim 45p per business mile for the first 10,000 miles, then 25p per mile after that. No receipts needed for fuel, insurance, or running costs. The flat rate covers everything: fuel, wear and tear, insurance, road tax, depreciation. One number per mile, done.

Method 2: Actual costs. You add up everything you spend on the vehicle (fuel, insurance, road tax, MOT, servicing, repairs, finance interest, depreciation) then apply a business-use percentage based on your mileage split. If 70% of your miles are business, you claim 70% of the total costs.

Most self-employed people use simplified mileage. It's easier, requires less paperwork, and for many drivers it produces a higher claim than actual costs. The comparison is covered in detail in the mileage allowance example.

The choice you make here determines whether fuel VAT is relevant to you at all.

Simplified mileage: no VAT to reclaim

If you use the 45p/25p mileage rate, there is no separate VAT claim on fuel. Full stop.

The mileage allowance is a flat rate that covers all vehicle costs, including fuel. HMRC has baked a fuel element into the 45p figure. You can't then also reclaim the VAT on the fuel you bought, because you'd be double-counting: claiming the fuel cost twice.

This catches people out because they see the VAT on their fuel receipts and think they're missing out. They're not. The 45p rate is designed to be generous enough to cover fuel costs (including the VAT portion) plus all other running costs, without needing receipts.

According to HMRC's simplified expenses guidance, when you use the mileage rate, "you cannot claim any other motoring expenses such as insurance, repairs, fuel and so on." That includes VAT on those expenses.

Actual costs + VAT registered: here's where it gets interesting

If you meet both of these conditions, you can reclaim VAT on fuel:

1. You use the actual cost method for vehicle expenses (not simplified mileage)
2. You are VAT registered

If you're not VAT registered, there's nothing to reclaim regardless of which method you use: you're not submitting VAT returns, so VAT recovery doesn't apply to you.

If you are VAT registered and using actual costs, you can reclaim the VAT on all your vehicle expenses in proportion to business use. That includes fuel, servicing, repairs, and any other VAT-bearing costs. You need receipts for everything, and you need to calculate the business-use percentage accurately.

For fuel specifically, you have two options.

Option 1: VAT on actual fuel receipts

The straightforward approach. Keep every fuel receipt, add up the total, extract the VAT (fuel VAT is charged at the standard 20% rate), and reclaim the business-use proportion.

Say you spend £3,000 on fuel in a year. The VAT content is £500 (3,000 ÷ 6, since VAT at 20% means the VAT is one-sixth of the gross amount). If 60% of your mileage is business, you reclaim £300 of input VAT.

This is accurate but requires meticulous record-keeping. Every single fuel receipt, every fill-up, for the entire year. Lose a receipt and that fill-up's VAT is gone. Most people find this tedious, which is why the second option exists.

Option 2: HMRC advisory fuel rates

HMRC publishes advisory fuel rates every quarter. These rates represent the estimated fuel cost per mile based on engine size and fuel type. They're primarily designed for employers reimbursing employees for business travel in company cars, but VAT-registered sole traders using actual costs can also use them to calculate the fuel element for VAT recovery.

The current advisory fuel rates (as of early 2026) are:

Electric vehicles have a separate advisory rate of 7p per mile.

To use these rates for VAT recovery, you multiply the advisory rate by your business miles, then extract the VAT from that figure. For example: 8,000 business miles in a 1.6-litre petrol car at 15p per mile = £1,200. The VAT content is £200 (one-sixth of £1,200). You reclaim £200 on your VAT return.

This is simpler than keeping every receipt, but you still need a detailed mileage log to justify the business miles figure. And you must keep at least one fuel receipt per VAT quarter to prove you actually bought fuel. HMRC won't accept advisory rate claims with zero evidence of fuel purchases.

Advisory fuel rates are not the mileage allowance

This is the single biggest source of confusion. People see "pence per mile" and assume advisory fuel rates and the mileage allowance (45p/25p) are interchangeable. They are completely different things used in completely different contexts.

If you use the 45p mileage allowance, advisory fuel rates are irrelevant to you. If you use actual costs and are VAT registered, advisory fuel rates give you a simpler way to calculate the fuel VAT you can reclaim. The two systems do not mix.

The VAT fuel scale charge: company cars only

One more fuel-related VAT mechanism worth addressing: the VAT fuel scale charge. This only applies to businesses that provide company cars and pay for fuel used privately by employees or directors.

The fuel scale charge is essentially a way of accounting for the private-use element of fuel paid for by the business. If your company pays for all fuel on a company car (including the driver's personal mileage), you must either:

• Apply the fuel scale charge: a fixed quarterly amount based on the car's CO2 emissions, which you add to your VAT output (effectively paying back the VAT on the private-use fuel), or
• Only reclaim VAT on fuel that's genuinely for business use (which means splitting every fill-up, which is impractical)

If you're a sole trader driving your own car, the fuel scale charge doesn't apply to you. It's a corporate mechanism. I mention it only because it appears in search results for "fuel VAT" and adds to the confusion.

What about electric vehicles?

If you drive an electric vehicle and use simplified mileage, the same rule applies: 45p/25p per mile, no separate VAT claim. The mileage rate is the same for EVs as for petrol and diesel.

If you use actual costs, you can reclaim VAT on the electricity used to charge the vehicle for business purposes. The advisory rate for EVs is currently 7p per mile. However, electricity for home charging is charged at 5% VAT (the reduced rate for domestic energy), not 20%. Public chargers typically charge at 20% VAT. The distinction matters for your VAT calculations.

For most EV drivers, the simplified mileage route is even more attractive than for petrol drivers. The actual running cost of an EV is roughly 4–6p per mile, but you claim 45p. The gap between the allowance and the actual cost is much wider, making the flat rate extremely generous.

Flat rate VAT scheme: a further complication

If you're on the flat rate VAT scheme, you generally cannot reclaim input VAT on purchases: that's the trade-off for the simplified calculation. The exception is capital goods over £2,000 including VAT.

This means if you're on the flat rate scheme, you cannot reclaim VAT on fuel regardless of whether you use actual costs. The flat rate percentage you charge on your sales is supposed to cover it. Some businesses find that the flat rate scheme saves them money overall despite losing the fuel VAT recovery. Others find the opposite. It depends on your turnover, your expenses, and the flat rate percentage for your trade sector.

If fuel is a major expense for your business (delivery drivers, mobile tradespeople, couriers), it's worth running the numbers to see whether the standard VAT scheme with fuel VAT recovery gives you a better result than the flat rate scheme. Your accountant can model both scenarios.

Record-keeping requirements

Whichever method you use, HMRC has specific expectations:

• Simplified mileage: A contemporaneous mileage log recording the date, start point, destination, business purpose, and miles for each journey. No fuel receipts needed.
• Actual costs (no VAT claim): All vehicle expense receipts, plus a mileage log to determine the business-use percentage.
• Actual costs with VAT recovery: All of the above, plus valid VAT invoices (fuel receipts showing the VAT registration number, VAT amount, and supplier details). At least one fuel receipt per VAT quarter if using advisory rates.

The mileage log requirement is the same across all methods. The difference is what else you need on top of it. With simplified mileage, the log is the only record. With actual costs and VAT, you're keeping the log plus every receipt plus VAT invoices. The administrative burden scales significantly.

Common mistakes

The errors I see most often:

• Claiming 45p per mile AND reclaiming fuel VAT. This is double-dipping. You cannot do both. If HMRC spot it, you'll repay the VAT plus penalties.
• Using advisory fuel rates as a mileage allowance. Advisory rates cover fuel only. The mileage allowance covers all vehicle costs. Claiming 15p per mile instead of 45p because you looked at the wrong table is leaving money on the table.
• Reclaiming fuel VAT when not VAT registered. If your turnover is below the VAT threshold (£90,000 from April 2024) and you haven't voluntarily registered, you're not submitting VAT returns, and there's no mechanism to reclaim VAT on anything.
• Forgetting to keep fuel receipts when using advisory rates. You need at least one per VAT quarter as evidence. No receipt, no claim.
• Claiming 100% of fuel VAT when there's personal use. If you use the car for personal journeys too, you can only reclaim the business proportion. Claiming 100% when you clearly drive to the shops at weekends is asking for trouble.

So what should you actually do?

For most self-employed people reading this, the answer is straightforward:

Use simplified mileage. Forget about fuel VAT.

The 45p/25p rate is generous for most drivers, requires minimal paperwork, and eliminates the entire fuel VAT question. You need a mileage log and nothing else. No fuel receipts, no quarterly advisory rate lookups, no business-use percentage calculations.

If you're VAT registered and you use actual costs because your accountant has determined it gives a better result for your specific situation, then yes: reclaim fuel VAT using either your actual receipts or the advisory fuel rates. But this should be a deliberate, considered choice, not something you stumble into because you read a misleading blog post.

And if you're not VAT registered, fuel VAT is entirely irrelevant to you. Focus on tracking your miles accurately and claiming the full 45p/25p. Every mile you miss is money you're giving away. The HMRC mileage rates guide covers the rates and thresholds in detail.

The single most valuable thing you can do is track every business mile. The method you use to claim them matters less than whether you're recording them all in the first place.
