Using a car for business purposes creates a separate set of tax considerations on top of standard road tax. Whether you are a company car driver, a sole trader using your personal vehicle for work, or a business owner with a fleet, understanding how car tax interacts with business use is essential for staying compliant and minimising costs.
Company Car Benefit in Kind Tax
If your employer provides you with a car for personal use, you pay Benefit in Kind (BIK) tax. BIK is calculated as a percentage of the vehicle's P11D value — the list price including VAT and delivery charges. The percentage is based on the vehicle's CO2 emissions: zero-emission company cars attract a 2% BIK rate in 2026-27, rising to 5% by 2027-28. A high-emission diesel company car can attract 37% BIK. Your employer reports BIK via PAYE and you pay it through your tax code.
Van Excise Duty for Business Vans
Vans used for business purposes pay a different VED rate than cars. The standard annual rate for a van is currently £290 per year. Electric vans attract a reduced rate of £0 for the first year and £0 standard rate. Businesses can claim capital allowances on van purchases and deduct running costs including road tax from their taxable profits. If a van is used privately, a van benefit charge may also apply.
Sole Trader Allowable Vehicle Expenses
Sole traders using their own car for business can claim vehicle expenses against tax. This includes a portion of road tax proportional to business use.HMRC allows you to claim either the standard mileage rate (45p per business mile for cars) or actual expenses including road tax, insurance, fuel and maintenance. Choose whichever gives the higher deduction. Keep detailed mileage logs to support your claim.
VAT on Road Tax
Road tax (VED) itself is not VAT-able, but if you are VAT-registered and use your vehicle exclusively for business, you may be able to reclaim 100% of the VAT on vehicle costs. If the vehicle is used for a mix of business and personal use, you can only reclaim a proportion. Consult an accountant to calculate the correct business use percentage. VAT on fuel (whether you use a fuel card or pay personally) has its own simplified scheme — the VAT fuel scale charge — which HMRC sets annually.
Fleet Operators and Multiple Vehicles
Businesses with five or more vehicles should consider fleet management systems that track VED status, MOT dates and fuel efficiency. Managing road tax centrally prevents vehicles accidentally running without tax. Many fleet operators use the DVLA fleet licensing service to manage multiple vehicles under one account. This simplifies renewals and reduces administrative overhead. Fleet operators can also access bulk discount rates on some vehicle services.
Electric Vehicle Tax Incentives for Businesses
Businesses receive enhanced capital allowances on zero-emission vehicles: 100% first-year allowance for cars with CO2 emissions up to 50g/km, and 100% for electric vans. This means the full cost can be deducted from taxable profits in the year of purchase. Company car BIK rates for EVs remain the lowest of any fuel type. These incentives make electric company cars significantly cheaper for businesses to provide and for employees to accept.
