Businesses purchasing vehicles for business use can claim tax relief through capital allowances. The rules differ significantly between passenger cars and commercial vehicles, and between vehicles with different CO2 emissions profiles. Understanding these rules helps businesses maximise their tax relief when acquiring vehicles.
Capital Allowances: The Basics
Capital allowances allow businesses to deduct the cost of qualifying capital expenditure from their taxable profits. For vehicles, the amount of relief available depends on whether the vehicle is classified as a commercial vehicle or a passenger car, and on its CO2 emissions profile. Capital allowances are claimed instead of deducting the purchase cost as an expense in the year of purchase.
First Year Allowances for Low Emission Vehicles
Vehicles with CO2 emissions of less than 50 grams per kilometre qualify for 100 percent first-year allowance, meaning the full cost of the vehicle can be deducted from taxable profits in the year of purchase rather than being spread over many years through writing down allowances. This represents a significant cash flow and timing advantage for businesses purchasing pure electric vehicles or plug-in hybrids with very low emissions. Pure electric vehicles with zero tailpipe emissions qualify automatically.
Writing Down Allowances for Standard Vehicles
Standard passenger cars that do not qualify for first-year allowances are placed in capital allowance pools. Cars with CO2 emissions of 50 grams per kilometre or more are placed in the main rate pool and attract an 18 percent reducing balance writing down allowance per year. Cars with CO2 emissions above 110 grams per kilometre are placed in the special rate pool and attract only an 8 percent reducing balance allowance per year, significantly slowing the rate of tax relief.

For a vehicle placed in the main rate pool at 25,000 GBP, the first-year writing down allowance would be 4,500 GBP (18 percent of 25,000). At a corporation tax rate of 25 percent, this saves 1,125 GBP in corporation tax in the first year, with further savings in subsequent years as the remaining balance continues to attract writing down allowance.
Lease Payments and Deductibility
Businesses using leased vehicles face different rules. Lease payments for cars with CO2 emissions of 50 grams per kilometre or less are fully deductible for tax purposes. Lease payments for cars with CO2 emissions above 50 grams per kilometre are only 50 percent deductible, reflecting the assumption that these vehicles may have some private use element. This creates a tax advantage for leasing low-emission vehicles compared to high-emission vehicles on an after-tax cost basis.

Frequently Asked Questions
Q: How much is car tax (VED) in the UK 2026?
Car tax rates in the UK depend on your vehicle's CO2 emissions and list price. Standard rates start from £190 per year for petrol and diesel cars, with zero-rated VED for EVs. First-year rates vary from £0 to £2,605 depending on emissions. Additional premiums apply for vehicles over £40,000.
Q: How do I check if my car is taxed online?
You can check your vehicle's tax status for free on the Gov.uk website at gov.uk/check-vehicle-tax. You'll need your vehicle's registration number (number plate). You can also check via the Motor Insurance Database to verify road tax and insurance status simultaneously.
Q: Can I get a refund on car tax if I sell my vehicle?
Yes — if you sell or scrap your vehicle, you can claim a refund on any full months of remaining road tax. Contact DVLA with the V11 reminder letter or apply online at gov.uk. Refunds are usually processed within 4-6 weeks.
Q: Is road tax refund available when transferring ownership?
No — road tax does not transfer with the vehicle. When you sell your car, the tax is automatically cancelled and any remaining months are refunded to you by DVLA. The new owner must tax the vehicle immediately. As a buyer, always verify the vehicle's tax status before purchasing.
Q: What is the luxury car tax threshold in the UK 2026?
The additional rate for vehicles over £40,000 (list price) adds £410 per year to standard VED rates for years 2-6 of registration. This surcharge brings the annual cost for high-emission vehicles over £40,000 to around £600-690 per year. Pure EVs under £40,000 pay zero VED.
