HGV Fuel-Card Bookkeeping and VAT Reconciliation
A fuel card is a credit arrangement, not a purchase record. The money leaving your bank each week is a payment against an account. The VAT you can recover depends on the statement or invoice behind that account, not on the payment.
Posting from the bank is the error that causes most fuel VAT problems in haulage, and it is easy to make because the bank feed is the thing that appears in the software on its own.

- Who this is for
- HGV owner-drivers and haulage operators buying diesel on fuel cards or through a bunkering arrangement.
- The problem
- Fuel is usually the largest single cost in a haulage business and the one most often posted incorrectly, which puts the largest single VAT reclaim on the weakest evidence.
The Right Way Round
The statement is the accounting document
The fuel card provider issues a statement or VAT invoice covering a period. That document, with the VAT shown, is what goes into the purchase ledger. It is the evidence HMRC expects to see behind the reclaim.
The bank payment settles the account
When the direct debit leaves, it is allocated against the statement already posted. It is not a fuel expense in its own right, and posting it as one duplicates the cost or creates a reclaim with no invoice behind it.
Transactions carry the vehicle registration
Card statements list the vehicle or card against each transaction. Coding fuel to the vehicle rather than to a single fuel account is what makes per-truck cost per mile possible later.
Litres are recorded, not just pounds
Litres against miles is your real mpg. Without the litres, the fuel line is a cost and nothing more.
Where the VAT Goes Wrong
- VAT reclaimed on the gross bank payment, so the reclaim is overstated and unsupported.
- Statements filed but never posted, so a genuine reclaim is missed entirely for the quarter.
- Foreign diesel treated as UK input VAT. VAT charged in another country is not recoverable on a UK VAT return, and follows a separate refund process if it is recoverable at all.
- Non-fuel items on the card, such as tolls, AdBlue, parking and shop purchases, posted at the standard rate without checking what was actually charged.
- A card used for a private vehicle, with the fuel left in the business purchase ledger.
Bunkered Fuel
If you take a bulk delivery into your own tank, the invoice is the purchase and the VAT is recoverable on it in the normal way. The complication is that the cost hits one period and the consumption spreads over several, which distorts the monthly figures unless the fuel in the tank is treated as stock.
For a small fleet, a simple monthly dip and a stock adjustment is usually enough to keep the per-vehicle numbers honest without building a full inventory system.
What Good Looks Like
A fuel process that survives a VAT inspection and produces useful numbers
- Statements downloaded monthly and posted as purchase invoices with the VAT shown.
- Bank payments allocated against those invoices rather than posted as costs.
- Every transaction coded to a vehicle registration.
- Litres captured alongside cost.
- Non-fuel items on the card reviewed rather than assumed to be standard rated.
- Foreign fuel separated out and excluded from the UK input tax claim.
- A monthly check that litres against miles produces a plausible mpg, which is also the fastest way to spot a card being used where it should not be.
Common Questions
Can I reclaim the VAT on diesel bought on a fuel card?
Yes, where the fuel is used for business and you hold the VAT invoice or statement from the card provider showing the VAT charged. The reclaim rests on that document, not on the payment leaving your bank.
What about VAT on diesel bought abroad?
VAT charged in another country is not input tax on your UK VAT return. Depending on the country and the amount, a separate refund claim may be possible, and it has its own deadlines and evidence requirements. Keep those receipts separate from the outset rather than untangling them later.
My fuel card statement does not show VAT separately. What do I do?
Ask the provider for a VAT invoice. Most issue one alongside the transaction statement. Without a document showing the VAT charged, the reclaim is not properly supported, and reconstructing it by applying a percentage to the total is not a substitute.
Is it worth coding fuel by vehicle if I only have two trucks?
Yes, and two is the easiest time to start. The coding costs nothing extra at the point of posting, and it is the difference between knowing which truck is drinking and finding out when the engine goes.
