Buy a new double cab pickup on or after 6 April 2025 and HMRC will almost certainly tax it as a car, not a van. That single reclassification is the heart of the current double cab pickup tax rules, and it can add several thousand pounds a year to the cost of running one as a company vehicle. VAT treatment has not changed. Capital allowances have. Benefit-in-kind charges have changed the most. Vehicles bought, leased, or ordered before 6 April 2025 keep the old van treatment for a while longer, but not indefinitely.
Benefit in Kind Under the New Rules
Any employee who uses a company double cab pickup for private journeys owes benefit-in-kind tax. Under the old van treatment, that was a fixed annual charge. Under car treatment, it is a percentage of the vehicle’s list price linked to its CO2 emissions, and the percentages for a diesel pickup sit near the top of the scale.
The flat van benefit charge is £4,020 for 2025/26 and rises to £4,170 for 2026/27. Where the employer also pays for private fuel, a separate van fuel benefit of £769 applies for 2025/26. A 40% taxpayer with a van-classified pickup pays roughly £1,600 in income tax on the benefit.
Switch the same vehicle to car treatment and the maths changes completely. A diesel pickup with CO2 emissions around 190 g/km attracts a BIK rate of 37% of list price. On a £42,000 pickup, that produces a taxable benefit of £15,540 rather than the £3,960 flat van charge that applied the year before. For a 40% taxpayer, the income tax bill jumps from about £1,584 to £6,216, an increase of more than £4,600 in a single year. The employer’s Class 1A National Insurance rises in parallel, from around £546 to over £2,100. Diesel vehicles that fail the RDE2 emissions standard carry a further 4% supplement, though the overall BIK percentage is capped at 37%.
Capital Allowances: AIA Is Off the Table
Before April 2025, a double cab pickup with a payload of at least one tonne was treated as plant and machinery. Businesses could claim the Annual Investment Allowance and write off the full purchase price in the year of purchase, up to the £1 million AIA cap, or use full expensing at 100% on qualifying new assets.
From 1 April 2025 for corporation tax and 6 April 2025 for income tax, most double cab pickups are cars for capital allowances. Cars get neither the AIA nor full expensing. A pickup with CO2 emissions above 50 g/km drops into the special rate pool and attracts a writing-down allowance of 6% a year on a reducing-balance basis. A vehicle you once deducted in full in year one now takes more than five years to recover roughly a third of its cost. For a smaller business buying a £40,000-plus pickup, the cash-flow impact is real.
VAT Recovery Has Not Changed
The one bright spot is VAT. HMRC has confirmed that a double cab pickup with a payload of one tonne or more is still not a car for VAT purposes. A VAT-registered business buying one mainly for business use can recover the 20% VAT on the purchase price, regardless of how the vehicle is classified for BIK or capital allowances.
Where there is private use, the business must either apportion the input tax to reflect business-versus-private mileage or account for output tax on the private element. Mileage records need to be accurate. Without them, HMRC can challenge the whole input tax claim on audit.
The One-Tonne Payload Test Still Matters
Payload is the difference between a vehicle’s maximum gross weight and its unladen kerb weight. If that figure reaches 1,000 kilograms or more, the pickup keeps its commercial classification for VAT, even though it is now a car for income tax and corporation tax.
Hitting one tonne is tighter than buyers often assume. A pickup with a nominal payload of 1,010 kg can drop under the threshold once a hard-top canopy, heavy-duty bumper, or tow bar goes on. HMRC’s guidance uses the example of a hard top cutting payload from 1,010 kg to 965 kg, which flips the vehicle from commercial to car for every tax purpose where the payload test still applies. Manufacturers sometimes define payload differently from HMRC, so the official gross-vehicle-weight-minus-kerb-weight figure is the one to work from.
Transitional Protection for Existing Vehicles
Businesses that committed to a double cab pickup before the rules changed get some protection, but the two taxes have different windows.
Benefit in Kind
Employers who purchased, leased, or ordered a double cab pickup before 6 April 2025 can keep treating it as a van for BIK purposes until the earliest of three dates: disposal of the vehicle, expiry of the lease, or 5 April 2029. That gives up to four years to run down existing arrangements without a sudden tax hit for the driver. The 2029 date is worth putting in the diary, because renewal on the same terms will move the vehicle onto car BIK rates.
Capital Allowances
The capital allowances window is much shorter. Expenditure incurred before 1 April 2025 (corporation tax) or 6 April 2025 (income tax) falls under the old rules. If a contract was signed before those dates but the spending falls after them, the old treatment still applies only if the expenditure is incurred before 1 October 2025. Miss that six-month deadline and the vehicle goes into the 6% special rate pool with no route back to the AIA.
What This Means If You Are Buying Now
For a new order placed today, expect the vehicle to be a car for BIK and capital allowances and a commercial vehicle for VAT if the payload clears one tonne. That split classification is now the normal position for a double cab pickup.
When comparing options, factor in the full cost gap. A panel van or single cab pickup with a payload above one tonne still qualifies for van BIK rates, the AIA, and full VAT recovery. The difference between a £4,020 flat van charge and a five-figure car BIK charge is large enough to change what employers put on the fleet list, and some are moving drivers into single cabs or panel vans specifically to sidestep the car treatment.
