The VAT road fuel scale charge is the price of convenience: reclaim all the VAT on fuel for a car that gets any private use, and instead of keeping mileage records you add a fixed charge — set by the car's CO2 band — to your output VAT each period. No logbooks, no splitting the school run from the site visit. Whether that convenience is worth paying for is pure arithmetic, and for a surprising share of businesses the honest answer is no: the scale charge quietly exceeds the VAT being recovered.
How the charge works
The scheme applies per car, per accounting period, wherever a business reclaims full input VAT on road fuel that includes private motoring. You look up the car's CO2 emissions figure in HMRC's table — revalued every year from 1 May — which gives a VAT-inclusive scale charge; the amount you actually add to box 1 as output tax is the VAT element, one-sixth of that figure. For the current year (1 May 2026 to 30 April 2027), the annual VAT-inclusive charges run from £657 for cars at 120g/km or less, through £1,314 at 150g/km, to £2,297 for anything at 225g/km and above — with quarterly and monthly equivalents for normal VAT staggers. In output-tax terms that is roughly £110 to £383 a year of actual VAT (£219 for the 150g/km car — £54.67 a quarter). The bands step in 5g/km increments between those points, and one charge applies per car with private use, however many drivers share it.
Two boundaries worth knowing: the scale charge is for cars only — vans are outside the scheme entirely, with genuinely private van fuel handled by apportionment instead — and it exists only because you chose full recovery. It is not a tax on having a car; it is the flat-rate giveback for reclaiming VAT on private fuel you were never entitled to recover.
The three options, honestly compared
Every VAT-registered business with cars faces the same three-way choice:
- Full reclaim + scale charge. Recover VAT on every fuel receipt; pay the fixed charge per car. Wins where fuel spend is high and private use is substantial — the sales fleet doing 25,000 miles a year each;
- Business-mileage reclaim only. Keep mileage records and reclaim VAT only on the business share — for mileage-allowance payments, valued off the advisory fuel rates, with fuel receipts retained (the mechanics are in our mileage rates guide). More admin, no scale charge, and usually the best answer for modest fleets with good expense apps;
- No fuel reclaim at all. Zero admin, zero scale charge, zero recovery. Legitimate, and genuinely optimal for businesses with low fuel spend — the consultancy with two directors' cars doing mostly private miles.
The break-even test takes five minutes per car: annual fuel VAT recovered versus the VAT element of the car's scale charge. For the 150g/km car, that element is £219 a year — recovered once the business buys about £1,314 of fuel for it annually (VAT being one-sixth of gross spend), assuming full recovery entitlement. Below that, full reclaim plus scale charge loses to reclaiming nothing at all; and wherever private mileage is genuinely low, the mileage-records method usually beats both. High-CO2, low-mileage cars are the classic losers: the top band's £383 of annual output VAT can exceed the input VAT a lightly-used car ever generates — a sum nobody re-runs after the car is bought.
Electric cars, hybrids and the modern fleet
The scale charge system is built on CO2 bands, which makes it increasingly a legacy scheme: pure electric cars have no fuel in the scale-charge sense — electricity is not "road fuel", so no scale charge arises, and VAT recovery on charging follows its own rules (business use at the workplace recoverable; home charging largely not, for companies). Hybrids sit in the table at their (low) CO2 figures, often making full reclaim plus a bottom-band charge attractive. A fleet transitioning to EVs should expect its scale charges to melt away — and should re-choose its fuel VAT method as the mix changes, rather than letting a 2019 decision run on autopilot.
The compliance points that get checked
VAT inspections test this area with three standard questions: are scale charges being applied for every car with private use where full fuel VAT is reclaimed (missing cars is the common assessment); are the charges on the current table (the figures move every May, and software defaults lag); and, where the business claims the mileage-only method, do the records actually exist? Directors' cars are the perennial finding — fuel through the company card, full VAT reclaimed, no scale charge, no records — which unwinds expensively over four years of returns.
The fix is annual hygiene: list the cars, confirm the method per car, update the charges each May, and re-run the break-even when the fleet or fuel prices change. It is a fifteen-minute job that our VAT returns team folds into the compliance cycle — and one of the first things a VAT health check catches when it has been skipped. Convenience is worth paying for; paying for it accidentally is not.
