You've got a profitable limited company, a car due for replacement, and a familiar temptation: put the next vehicle through the business and reduce the personal cost. Perhaps the company has £45,000 of profit available, and you're deciding whether that money should fund a new car or be extracted and used to buy one privately.
That decision isn't solved by spotting a low Benefit in Kind rate. You need to consider VAT recovery, corporation tax relief, capital allowances, running costs, Class 1A National Insurance, private use, cash flow and the car's eventual resale value. A company car can be efficient, particularly when the vehicle is electric, but a high-emission car can create a personal tax bill that wipes out the apparent saving.
The right answer depends on how the car will be used, how you draw money from the company and whether the company can comfortably carry the cost. This guide works through the ownership routes, BIK mechanics, VAT restrictions, capital allowances, a personal-versus-company comparison and the increasingly important timing question for electric cars.
Why Directors Run the Company Car Question
The director is looking at the company's bank balance after a strong trading period. There's enough profit to fund a new vehicle, but the choice isn't just “company money or personal money”. The company may buy the car, pay the insurance and absorb the running costs, while the director reports a taxable benefit personally. Alternatively, the director can extract money, pay the relevant personal taxes and buy the car without a company-car benefit.
That's why buying a car through a limited company is a commercial decision first and a tax decision second. The car must serve a genuine business and personal need. If it's mainly a family vehicle, the company structure may add reporting obligations without delivering a worthwhile saving. If it's a low-emission car used extensively for business, the balance can look very different.
The UK company-car regime remains well established. HMRC's July 2026 benefits-in-kind statistics show that the total taxable value of all Class 1A taxable benefits in kind reached £9.5 billion in 2024 to 2025, an increase of £0.6 billion year on year. That figure covers company benefits generally, not just cars, but it shows the scale of the system and why HMRC expects companies to report benefits accurately.
The questions that matter
Before approving a purchase, I'd want the director to answer four practical questions:
- What does the family need? A vehicle chosen only for its tax treatment can be a poor financial decision if it doesn't meet passenger, luggage or driving requirements.
- Can the company carry the cost? Loan repayments, lease rentals, insurance, maintenance and charging or fuel bills still affect cash flow.
- What will the director pay personally? The BIK charge is personal, and the result depends on the car's list price, its appropriate percentage and the director's marginal income tax rate.
- What's the alternative use of the cash? Dividends, pension funding, retained working capital or a privately owned vehicle may produce a better overall outcome.
For a useful comparison of the two broad approaches, see this guide to company car or cash allowance decisions. The important point is to model the whole arrangement, not just the corporation tax deduction.
Buy Outright, Lease, or Salary Sacrifice
A limited company can provide a director's car in several ways. The three routes most often considered are outright purchase, contract hire and salary sacrifice. They don't create the same ownership, cash flow or tax profile.
Buy outright
The company pays for the vehicle and records it as an asset. It carries the depreciation and residual-value risk, although corporation tax relief may arise through capital allowances. The company can also pay eligible running costs, subject to the normal rules around private use and deductibility.
This route uses more cash at the start, but there's no lease-end return process and the company owns the car. If the vehicle is sold later, the disposal proceeds affect the tax calculation. The director still faces a BIK charge if the car is available for private use.
Contract hire
The company pays regular rentals, usually under an agreement with an end date and mileage assumptions. The monthly profile is easier to budget, and the leasing provider carries much of the residual-value risk. VAT treatment needs careful checking, because private use normally restricts recovery on lease rentals.
Contract hire suits a director who values predictable costs and changes cars regularly. It doesn't necessarily mean the company owns the car at the end, so the contract terms matter as much as the headline monthly payment.
Salary sacrifice
The director or employee gives up gross salary in exchange for access to the vehicle. That can reduce the amount of salary subject to income tax and employee National Insurance, but the car benefit still needs to be reported and taxed through the BIK rules. Salary sacrifice also changes contractual pay, which can affect affordability assessments, pension arrangements and other employment-linked calculations.
For electric vehicles, review the wider mechanics in this guide to salary sacrifice electric vehicles. Don't assume salary sacrifice automatically beats company ownership. The gross-pay reduction, BIK charge, employer costs and vehicle agreement must be assessed together.
| Feature | Buy Outright | Contract Hire | Salary Sacrifice |
|---|---|---|---|
| Who owns the car | The company | Usually the leasing provider | Usually the employer or leasing provider |
| Initial cash requirement | Highest at purchase | Spread across rentals | Usually spread through salary reduction |
| Residual-value risk | Company carries it | Generally shifted to provider | Depends on the underlying arrangement |
| BIK position | Applies when available for private use | Applies when available for private use | Applies despite the salary exchange |
| VAT focus | Purchase VAT is usually blocked in mixed use | Rental VAT is usually partly restricted | Depends on the leasing and employment arrangement |
| Best fit | Long-term ownership and strong cash reserves | Predictable motoring costs | Structured employee benefit, especially where EV terms work |
The director's tax position changes according to the benefit, not just the funding method. A cheaper way to fund an expensive, high-emission car doesn't make the personal BIK charge disappear.
How Benefit in Kind Actually Works
The BIK calculation starts with the vehicle's P11D list price, not necessarily the amount the company paid. HMRC's company-car rules include VAT, number plates, delivery and standard accessories in the list price, then apply the appropriate percentage for the car's emissions and the tax year. The published 2026/27 company-car tables show a 4% rate for zero-emission cars and rates rising to 37% for the highest-emission bands.
The calculation is straightforward:
- Identify the P11D list price.
- Find the appropriate percentage for the tax year.
- Multiply the list price by that percentage.
- Apply the director's marginal income tax rate.
For example, a £40,000 zero-emission car at 4% produces a taxable benefit of £1,600. A director taxed at 40% would face a personal income tax charge of £640 on that benefit, before considering any separate fuel benefit.
What the company pays
The company pays Class 1A employer NIC on the taxable benefit. The exact liability depends on the applicable employer NIC rate and the reported benefit, so it belongs in the company-side model rather than being treated as an afterthought.
The director's BIK tax is normally collected through PAYE or reflected in the tax coding notice. The company reports the car benefit on form P11D. The charge applies because the vehicle is available for private use, not because the company bought it with cash rather than finance or leased it.
Fuel is a separate issue. Where private fuel is provided, the fuel benefit calculation can materially change the result, so a company should model private fuel separately instead of assuming it's included in the car figure.
Why the percentage matters so much
HMRC's formal company-car schedule sets the zero-emission appropriate percentage at 3% in 2025/26, 4% in 2026/27 and 5% in 2027/28, with later increases planned. For higher-emission cars, the percentage can reach 37%, meaning the same list price can produce dramatically different taxable benefits depending on the vehicle's CO2 band.
Use the car benefit tax calculator to test the list price, BIK percentage, personal rate and employer NIC before committing. The headline rate is only useful when it's applied to the actual vehicle and the actual taxpayer.
VAT on Cars Bought or Leased Through a Company
VAT is where many company-car calculations go wrong. Buying the car through the company doesn't automatically make the VAT reclaimable. HMRC's VAT on motoring expenses guidance treats cars in normal mixed-use situations restrictively.
For an outright purchase, input VAT recovery is generally blocked where the car has private use. Full recovery is usually limited to a genuine business-only vehicle, such as a pool car or driving-school vehicle, with no private use at all. A director taking the car home, using it for family journeys or treating ordinary commuting as private availability will usually prevent the company from satisfying that test.
Leasing has a different practical benchmark. Where there's private use, the company can usually reclaim 50% of the VAT on lease rentals, rather than recovering all the VAT. That restriction is designed to account for private availability and means the lease quotation needs to be assessed net of the VAT the company can recover.
| Scenario | Input VAT Treatment | Conditions |
|---|---|---|
| Company buys a mixed-use car | Recovery is normally blocked | Private use prevents full recovery |
| Company leases a mixed-use car | 50% of VAT on lease rentals can usually be reclaimed | The company must account for the private-use position and retain proper records |
| Genuine pool car | Full recovery may be available | No private use and access controlled by the business |
| Driving-school vehicle | Full recovery may be available | The vehicle must be used for qualifying business activity |
| Stock-in-trade vehicle | Treatment can differ | The car must be held for resale or another qualifying purpose |
Fuel needs its own review. VAT recovery on fuel used privately can be restricted or require an adjustment, even where the company has recovered VAT on some motoring costs. HMRC's VAT valuation manual explains that private use can require output tax on the taxable private-use proportion of relevant costs.
Practical rule: Decide the intended use before choosing the ownership route. The VAT result follows the facts, not the invoice name.
A mileage log remains important. It supports business-use claims and helps separate business journeys from private journeys. For broader treatment of business motoring costs, see this guide to VAT on business expenses.
Worked Example Personal vs Company Ownership
Consider one £40,000 internal-combustion-engine saloon, with emissions of 30 g/km CO2, used by a higher-rate director. This is an illustrative comparison, not a quotation of the exact BIK percentage for that vehicle. The appropriate percentage must be checked against the HMRC table for the relevant tax year and the vehicle's precise specification.
The private ownership route
The director extracts enough money to buy the car personally. The company doesn't own the vehicle, so there's no company-car BIK or Class 1A NIC on that car. The director personally carries the insurance, fuel, repairs and depreciation.
The company can reimburse business mileage at the approved rate, provided the journeys qualify and the records support the claim. The stated benchmark is 45p for the first 10,000 business miles and 25p thereafter, but the director must apply the rate relevant to the circumstances and tax year. The mileage payment isn't a substitute for a complete cost comparison. A director who drives relatively little for business may not recover much of the private ownership cost through mileage.
The company ownership route
The company buys the car, pays the running costs and reports the vehicle as a benefit. The company may claim capital allowances under the relevant pool, but the exact rate depends on the car's qualifying emissions and the tax rules applicable at the date of acquisition. The director pays income tax on the BIK value at the marginal rate, while the company pays Class 1A NIC on that benefit.
The company route can look attractive because company funds pay for the asset and operating costs. The calculation changes once you add the personal BIK tax, employer NIC, unrecovered VAT and the eventual loss in value. Corporation tax relief reduces the company's cost, but it doesn't remove the director's personal charge.
| Cost Item | Personal Ownership (£) | Company Ownership (£) |
|---|---|---|
| Purchase price | Paid personally from extracted funds | Paid by the company |
| VAT recovery | No personal VAT recovery | Usually restricted for mixed use |
| Capital allowances | None personally | Available under the relevant car pool |
| Insurance, repairs and fuel | Paid personally | Paid by the company, subject to tax treatment |
| Business mileage | Claimed from the company at approved rates | Business use recorded, with company paying costs |
| BIK income tax | None | List price multiplied by the appropriate percentage, then director's tax rate |
| Class 1A NIC | None on the private car | Payable by the company on the taxable benefit |
| Corporation tax effect | No company deduction for personal ownership cost | Relief may arise on qualifying company expenditure |
| Net result | Depends on extraction tax, mileage and depreciation | Depends on BIK, NIC, VAT, allowances and running costs |
The requested comparison often uses a 25% corporation tax rate and a 40% marginal income tax rate, but those rates must match the director's actual circumstances. The precise annual net cost can't be stated responsibly without the tax year, BIK percentage, business mileage, financing cost, insurance, fuel, maintenance and expected resale value.
For this particular car, the 30 g/km emissions figure doesn't by itself provide the appropriate percentage. Check the official band before calculating the BIK. A small change in the applicable percentage can alter the director's personal liability, especially where the list price is high.
The company route wins on structure only when the company-side deductions and running-cost savings outweigh the director's BIK and the employer's NIC.
Capital Allowances and the Paperwork Behind the Car
A company-owned car isn't written off for corporation tax because the company paid for it. HMRC's business-car capital allowances rules allow a company to claim 100% first-year allowances, 14% main-rate allowances each year or 6% special-rate allowances each year, depending on the qualifying circumstances and vehicle classification. The 14% rate applies from 1 April 2026 for Corporation Tax payers and from 6 April 2026 for Income Tax payers, while the 100% first-year rate applies from 1 April for all businesses.
The rate must be checked against the vehicle and acquisition date. Don't copy an allowance percentage from an old calculation into a new purchase decision.
What the company must record
Once the company provides a car, the bookkeeping becomes more involved. Keep the purchase invoice, financing or lease agreement, vehicle details, running-cost invoices and mileage records together.
The company also needs to:
- Report the car benefit: Include the vehicle on form P11D where required.
- Report private fuel separately: Fuel benefit and private fuel treatment need their own review.
- Pay Class 1A NIC: The liability is paid by the employer by the applicable deadline following the tax year.
- Support business mileage: A mileage log should identify business and private journeys clearly.
- Reconcile PAYE: The director's income tax on the benefit should be collected through PAYE or reflected in the tax code.
Running costs such as insurance, repairs, business fuel, road tax and finance costs may be deductible for corporation tax, but private use still matters. A company can't treat every motoring cost as a pure business expense simply because the vehicle appears on the company balance sheet.
Retain the supporting records for at least six years. That period gives the company a clear audit trail for invoices, mileage, benefit reporting and tax computations. Weak records create problems even where the underlying ownership decision was sensible.
The Timing Trap Around Electric Company Cars
Electric cars remain structurally attractive for company-car tax, but the advantage isn't frozen. HMRC's published schedule sets the zero-emission appropriate percentage at 3% for 2025/26, 4% for 2026/27 and 5% for 2027/28. The electric company-car tax rate analysis also highlights the practical timing issue: a director deciding whether to act now or wait must compare the cost of the rising BIK rate with the cost of delaying the vehicle.
HMRC's July 2026 statistics record fully electric cars in benefit-in-kind records rising from 342,000 to 467,000 in one year. That increase doesn't prove that every director should buy an EV, but it confirms that electric company cars are becoming a more prominent part of the benefit system.
The numbers over the tax years
The table below applies the published EV rates to a £40,000 car and then applies a 40% personal tax rate. It shows the BIK value, not the full cost of owning the vehicle.
| Tax Year | EV BIK Rate | BIK Value on £40,000 Car | Director Tax at 40% |
|---|---|---|---|
| 2022/23 | Not stated in the verified data | Cannot be calculated from the verified data | Cannot be calculated from the verified data |
| 2023/24 | Not stated in the verified data | Cannot be calculated from the verified data | Cannot be calculated from the verified data |
| 2024/25 | Not stated in the verified data | Cannot be calculated from the verified data | Cannot be calculated from the verified data |
| 2025/26 | 3% | £1,200 | £480 |
| 2026/27 | 4% | £1,600 | £640 |
| 2027/28 | 5% | £2,000 | £800 |
The figures for 2025/26 to 2027/28 follow HMRC's published rates. The earlier years aren't populated because the verified information here doesn't provide their rates, and guessing would produce a misleading comparison.
The increase is modest in isolation on a £40,000 car, but the decision usually involves more than one year. A director should model the full ownership period, the likely list price, company cash flow, charging costs, insurance and resale value. The calculation also changes for a director taxed at a higher marginal rate, or where salary and dividends place the individual in a different tax position.
Buy now or wait
Waiting can preserve cash and allow more time to compare models. It can also mean the car is acquired under a higher BIK percentage, while the company continues paying for an existing vehicle. Buying now may lock in the current tax-year treatment and allow the company to start absorbing eligible running costs, but it commits cash and may leave the company with an asset that falls in value.
My rule is direct: if the car is needed for business, the company has profit and cash to absorb it, and the vehicle is electric, buying now can still beat most internal-combustion alternatives. The advantage is narrowing each tax year, so don't treat today's low percentage as permanent.
Professional input earns its fee when any of these trigger points apply:
- Income mix: Salary and dividends are approaching the £100,000 personal allowance taper.
- Mileage pattern: Private use is minimal and could affect the VAT and benefit analysis.
- Company plans: A sale or major restructure is likely soon.
- Multiple vehicles: Several company cars may aggregate BIK and complicate reporting.
- Shared driving: A spouse or second director also drives the vehicle.
A competent accountant or tax adviser can often justify the fee by identifying the correct capital-allowance treatment and preventing Class 1A NIC errors. They should show the calculation, not just recommend a company car because it sounds tax-efficient.
Your next four actions
- Pull the last three months of mileage records and separate business journeys from private use.
- Check the current-year P11D position for any existing car or fuel benefit.
- Model three years of running costs under outright purchase, contract hire and personal ownership.
- Book a structured 30-minute review before signing an order or lease agreement.
