Can My Limited Company Claim Tax Relief On A Company Car In 2026/27?

If you are a director thinking about putting a car through your limited company, the decision is a company-side calculation before it is anything else: what relief the company gets, how fast it gets it, and what the car adds to the company's own costs. This page works through that side, capital allowances, lease versus buy, VAT and the employer National Insurance, with full worked numbers for 2026/27.

The director's side, the P11D reporting, the fuel benefit trap and what happens when you pay for fuel personally, is covered separately in our guide to reporting a company car on a P11D when the director pays for fuel.

What Your Company Can Claim: Capital Allowances by CO2 Band

There is no "company car tax relief" claim form. The relief arrives through capital allowances on the corporation tax return (CT600), and the rate depends entirely on the car's CO2 emissions. Cars are excluded from the Annual Investment Allowance, from full expensing and from the 40% first year allowance, so the CO2 band is the whole story.

Zero-emission cars: 100% first year allowance

A new and unused car with CO2 emissions of 0g/km qualifies for a 100% first year allowance under CAA 2001 s.45D. The company deducts the full purchase price from taxable profits in the year of purchase, with no cap on the car's cost.

Example: your company buys a new electric car for £35,000. The full £35,000 comes off taxable profits in year one. At the 19% small profits rate that saves £6,650 of corporation tax; at 25% it saves £8,750; in the marginal relief band (profits between £50,000 and £250,000) the effective saving is around 26.5%, so roughly £9,275.

Two conditions to watch: the car must be new and unused (a second-hand electric car drops into the 14% main pool instead), and a balancing charge can claw relief back when the car is later sold, because the pool value is nil.

1-50g/km: main pool at 14%

Cars in this band, mainly plug-in hybrids, go into the main rate pool at 14% a year on a reducing balance. The main-rate writing down allowance was cut from 18% to 14% from 1 April 2026 for corporation tax (FA 2026 s.28).

Example: a plug-in hybrid costing £35,000 with 40g/km CO2. Year one: 14% x £35,000 = £4,900. Year two: 14% x £30,100 = £4,214. It takes well over a decade to relieve most of the cost.

Over 50g/km: special rate pool at 6%

Most petrol and diesel cars fall here and get only 6% a year on a reducing balance. On a £35,000 car that is £2,100 in year one, £1,974 in year two, and so on. The rate is the same whether the car costs £15,000 or £50,000.

Electric vs Petrol: The Full Worked Comparison

Most comparisons stop at the capital allowance and the director's income tax. The company also pays Class 1A employer National Insurance at 15% on the benefit-in-kind value, and that belongs in the comparison because it is a real cash cost of the choice.

Take a director in Preston on £50,000 of salary and dividends (a basic rate taxpayer), choosing between two £35,000 cars in 2026/27.

New electric car (0g/km, 4% BIK in 2026/27):

• Capital allowance: 100% FYA, £35,000 deducted in year one. Corporation tax saved at 19%: £6,650.
• Benefit-in-kind: £35,000 x 4% = £1,400. Director's income tax at 20%: £280 a year.
• Class 1A employer NIC: £1,400 x 15% = £210 a year (itself deductible, saving about £40 of corporation tax at 19%).
• Year-one position: £6,650 saved, against £280 + £210 - £40 = £450 of combined annual cost. Clearly ahead.

Petrol car (130g/km, 33% BIK in 2026/27):

• Capital allowance: 6% x £35,000 = £2,100 deducted. Corporation tax saved at 19%: £399.
• Benefit-in-kind: £35,000 x 33% = £11,550. Director's income tax at 20%: £2,310 a year.
• Class 1A employer NIC: £11,550 x 15% = £1,733 a year.
• Year-one position: £399 saved, against £2,310 + £1,733 = £4,043 of combined annual cost, before any deduction for the NIC. A clear net cost, repeated every year the car is held.

For reference, the 2026/27 appropriate percentages are: 0g/km at 4% (up from 3% in 2025/26), 1-50g/km at 4% to 16% depending on electric range, then 17% at 51-54g/km rising by one point per 5g/km to the 37% maximum, reached at around 150g/km and above. If the company also pays for private petrol or diesel, a separate fuel benefit applies using a £29,200 multiplier for 2026/27; how that charge works, and how directors avoid it, is covered on the P11D and fuel page.

Leasing vs Buying a Company Car

Leasing changes the company-side relief, not the director's tax.

Operating lease: the rentals are deductible as incurred. Where CO2 exceeds 50g/km, 15% of each rental is disallowed (the lease rental restriction); at 50g/km or below the rentals are fully deductible. For a high-emission car this is usually better than owning, because the alternative is the 6% pool.

Finance lease or hire purchase: broadly follows the buying treatment, with the capital cost going into the relevant pool (100% FYA, 14% or 6% by emissions) and the interest element deductible.

The practical rule of thumb: buy new electric (to capture the 100% FYA, which a lessee cannot claim), lease high-emission (to escape the 6% pool, accepting the 15% disallowance). The benefit-in-kind and Class 1A NIC are identical either way, so the lease-or-buy choice never fixes a bad BIK position.

VAT on Company Cars: The 50% Lease Block

On a purchase, input VAT is 100% blocked if the car is available for any private use at all, which for a director's car it almost always is. Full recovery is realistic only for genuine pool cars, taxis or driving-school cars. Electric cars get no special treatment.

On a lease, the position is better: the company can recover 50% of the VAT on the lease rentals even where there is private use, and 100% of the VAT on any separate maintenance element. On a £500 + VAT monthly rental, that is £50 a month recovered. This is a genuine advantage of leasing that the corporation tax comparison alone misses.

Double Cab Pickups Are Now Cars (April 2025)

Until April 2025, a double cab pickup with a payload of one tonne or more was treated as a van, which meant AIA on purchase and a flat van benefit for the driver. That has ended. From 1 April 2025 (corporation tax) and 6 April 2025 (income tax), double cab pickups are treated as cars for capital allowances (HMRC guidance at CA23511), and from 6 April 2025 as cars for benefit-in-kind too.

For a typical diesel pickup that means: no AIA, relief at 6% a year in the special rate pool, and a CO2-based benefit percentage that will usually sit at or near the 37% maximum instead of the flat van charge. An electric double cab pickup fares far better: 100% FYA if new and unused, and the 4% zero-emission percentage.

Transitional rules soften the change: a pickup purchased, leased or ordered before 6 April 2025 keeps its van treatment until disposal, lease expiry or 5 April 2029, whichever comes first. For capital allowances, expenditure under a contract entered into before April 2025 and incurred before 1 October 2025 also kept the old treatment.

When a Company Car Makes Financial Sense

• New electric cars: usually yes. The combination of the 100% FYA, the 4% benefit percentage and a modest £210-a-year Class 1A cost is hard to beat if you would otherwise buy a car personally out of taxed income.
• Petrol and diesel cars: usually no. The 6% pool is slow, the benefit percentage is high, and the Class 1A NIC compounds the cost. The numbers above show a net annual cost of several thousand pounds on an ordinary £35,000 petrol car.
• Pickups: run the numbers fresh. The April 2025 reclassification removed the tax logic that made double cabs popular. A vehicle ordered before 6 April 2025 may still be worth keeping under the transitional rules.

Alternatives Worth Comparing

• Own the car personally and charge the company mileage. The approved rates for 2026/27 are 55p a mile for the first 10,000 business miles (up from 45p in 2025/26) and 25p after that, tax-free and NIC-free, with no benefit-in-kind because the car is yours. For a petrol car with real business mileage this usually beats the company car route.
• Salary sacrifice for an electric car. The optional remuneration (OpRA) rules that normally tax the salary given up do not apply to cars with CO2 of 75g/km or below, which is why EV salary sacrifice schemes work. For an owner-director, though, the straightforward company purchase usually does better because the company keeps the 100% FYA.
• Workplace charging. A chargepoint installed at the company's own premises is plant, and electricity provided there for a company car creates no fuel benefit, because electricity is not fuel for these purposes.

Practical Steps for Directors

1. Decide the company question first: buy new electric for the FYA, lease if the car must be high-emission, and model the Class 1A NIC alongside the corporation tax saving.
2. Check the P11D value before ordering. The benefit is based on list price including VAT, delivery and extras, not the discounted price you pay. A £40,000 electric car means a £1,600 benefit at 4%, still only £320 of basic rate tax a year.
3. Keep the invoice trail for the VAT position, especially on a lease where the 50% recovery on rentals and 100% on maintenance need separating.
4. Plan for the sale. A car that had a 100% FYA produces a balancing charge on disposal; the relief is a timing benefit, not a permanent one.
5. Sort the reporting side. The car goes on a P11D (or through payroll), the company files a P11D(b) by 6 July and pays Class 1A NIC by 19 July, or 22 July electronically. The full reporting walkthrough is on our P11D company car page.

Final Thoughts

The 2026/27 rules push one answer hard: if a limited company is going to provide a car, a new electric car is the only option where the company-side relief comfortably outweighs the combined cost of the director's tax and the employer's Class 1A NIC. For everything else, compare the company car against personal ownership with 55p mileage before you sign anything, and if the vehicle is a double cab pickup, assume car treatment unless it was ordered before 6 April 2025.
