Key takeaways
- Businesses on the VAT Flat Rate Scheme cannot reclaim input VAT on fuel; the flat rate percentage already accounts for typical input VAT costs.
- The VAT element of a fuel purchase is calculated using the VAT fraction of 1/6 at the standard 20% rate, and a valid VAT receipt must be held to support the claim.
- Vehicles used exclusively for business allow a full VAT reclaim on fuel; any private use means one of three mixed-use approaches must be applied instead.
- The fuel scale charge is a fixed HMRC charge by CO2 band that lets businesses reclaim all fuel VAT on mixed-use vehicles without tracking every individual journey.
- HMRC advisory fuel rates are reviewed quarterly and cover company car fuel costs; the 45p and 25p mileage allowance rates apply to income tax, not VAT recovery.
You can reclaim VAT on the fuel portion of your mileage expenses if you don't pay a fixed rate under the Flat Rate Scheme.
You can reclaim all the VAT on fuel if you use your vehicle exclusively for business.
If your vehicle is driven for both business and personal use, you may handle VAT in the following ways:
- Reclaim all the VAT and pay the fuel scale charge for your vehicle
- Reclaim the VAT on fuel you use for business trips
- Don't reclaim any VAT. This may be the better option if you use your vehicle for business purposes on rare occasions, such that the fuel scale charge exceeds the VAT you can reclaim.
