Company Car or Personal Car: Which Is More Tax-Efficient in 2026/27?

Introduction

Should a director buy a car personally and claim business mileage, or should the limited company buy or lease the car?

There is no single answer that applies to every director or every vehicle.

In 2026/27, a new fully electric company car can remain highly tax-efficient because the benefit-in-kind percentage is only 4% and a qualifying new and unused zero-emission car may attract a 100% first-year capital allowance. By contrast, a petrol or diesel company car with higher CO2 emissions can create a substantial personal tax charge and employer's Class 1A National Insurance liability.

The personal-car route has also become more attractive for some directors. From 6 April 2026, the approved mileage rate for an employee using their own car for qualifying business journeys increased to 55p per mile for the first 10,000 business miles. The rate remains 25p for business miles above 10,000.

The correct comparison therefore needs to consider much more than who pays the purchase price.

It should include:

• The car's original list price
• Its CO2 emissions and fuel type
• Whether the car is new or second hand
• Expected business and private mileage
• How the car will be financed
• The director's Income Tax rate
• The company's Corporation Tax position
• Employer's Class 1A National Insurance
• VAT recovery restrictions
• Running costs and insurance
• Expected ownership period and resale value
• Whether private fuel or electric charging will be provided
• The commercial cashflow effect on both the company and the director

This guide explains how the two routes work in 2026/27 and shows why electric cars, used cars and higher-emission cars can produce very different results.

Important: This article provides general UK tax information. It does not constitute personalised tax, financial, legal or vehicle-finance advice. Rates, reliefs and individual circumstances should be checked before a vehicle is acquired or an agreement is signed.

What is the difference between a company car and a personal car?

A company car is owned or leased by the limited company and made available to a director or employee.

The company normally pays some or all of the following:

• Purchase or lease costs
• Insurance
• Repairs and servicing
• Vehicle Excise Duty
• Breakdown cover
• Tyres
• Charging or fuel, depending on the arrangement

If the car is available for private use, the director or employee will normally be taxed on a company-car benefit. Private use includes ordinary commuting between home and a permanent workplace.

A personal car is owned or leased by the director personally. The director pays the acquisition and running costs. The company can reimburse qualifying business mileage using HMRC's approved mileage rates.

Provided the mileage payment does not exceed the approved amount and the journeys qualify, the payment can normally be received without Income Tax or National Insurance.

The key distinction is ownership and availability, not merely whose name appears on a fuel receipt.

A car used for work is not automatically a business-only car

Business use and private use must be separated.

A director may use a car for customer visits, site inspections, supplier meetings and other work journeys. That does not make every journey business travel.

Private travel normally includes:

• Ordinary commuting between home and a permanent workplace
• School runs
• Shopping
• Social journeys
• Holidays
• Weekend use
• Journeys made mainly for personal convenience

For company-car benefit purposes, the fact that the car is available for private use is usually enough to create a charge. The director does not need to drive a large number of private miles.

An attempted private-use ban must be genuine, clearly communicated and enforced. There must also be no actual private use. Simply describing a car as business-only in the accounts or insurance documents does not remove the benefit.

Pool cars can be exempt, but the conditions are strict. A qualifying pool car must generally be shared, used for business purposes, not ordinarily used by one employee to the exclusion of others, and normally kept at the business premises rather than near an employee's home.

Most cars taken home regularly by an owner-director will not satisfy the pool-car conditions.

HMRC confirms that private use of a company car includes commuting and publishes separate guidance on qualifying pool cars.

How is company-car tax calculated?

The taxable company-car benefit is broadly calculated using:

1. The car's price for tax purposes, usually its original list price plus taxable accessories.
2. The appropriate percentage for the car, based mainly on CO2 emissions and fuel type.
3. Adjustments for matters such as the period of availability, qualifying capital contributions and required private-use payments.

The calculation is not normally based on:

• The price the company actually paid
• The second-hand value
• The monthly finance payment
• The amount of private mileage
• The company's taxable profit

This creates an important trap with used cars.

Suppose a company buys a used electric car for £28,000, but the car's original list price was £50,000. The benefit is generally based on the relevant £50,000 list price, not the £28,000 purchase price.

The company-car benefit is treated as employment income for the director. The director pays Income Tax on the taxable amount at their marginal rate. Scottish taxpayers may pay different Income Tax rates from taxpayers in England, Wales and Northern Ireland.

The company also normally pays Class 1A National Insurance on the taxable benefit. The Class 1A rate for 2026/27 is 15%.

Company-car percentages for 2026/27

For a fully electric car with zero CO2 emissions, the appropriate percentage is 4% in 2026/27.

For cars with emissions between 1g/km and 50g/km, the percentage depends partly on the car's electric range. The percentage can be significantly higher than the fully electric rate where the electric range is limited.

For cars with emissions of 75g/km and above, the percentage increases through the emissions bands and can reach a maximum of 37%.

The company-car rate can therefore transform the result.

A £45,000 fully electric car at 4% produces a taxable benefit of £1,800.

A £45,000 car in the 37% band produces a taxable benefit of £16,650.

Both cars may cost the company the same amount, but the personal tax and employer National Insurance costs are completely different.

HMRC's 2026/27 company-car percentage guidance should be checked using the precise vehicle details before a decision is made.

Worked example: new electric company car

Assume a company buys a new and unused fully electric car in 2026/27.

The figures are:

• Purchase price including irrecoverable VAT: £45,000
• Original list price for benefit purposes: £45,000
• CO2 emissions: 0g/km
• Company-car percentage for 2026/27: 4%
• Available for the full tax year
• No director contribution or private-use payment

The taxable benefit is:

£45,000 x 4% = £1,800

The director's illustrative Income Tax cost would be:

• £360 at 20%
• £720 at 40%
• £810 at 45%

The company's Class 1A National Insurance would be:

£1,800 x 15% = £270

The company may also qualify for a 100% first-year capital allowance on the £45,000 cost, provided the car is new and unused, has zero emissions and is acquired within the qualifying period.

If the company obtains relief at 19%, the Corporation Tax effect of a £45,000 deduction would be £8,550.

If it obtains relief at 25%, the effect would be £11,250.

These figures illustrate the potential relief, not a guaranteed cash saving. The result depends on the company's taxable profits, accounting period, associated companies, losses, marginal relief position and the timing of the purchase.

The company has also spent £45,000 or taken on finance. Tax relief does not make the car free, and the company still needs sufficient cash and working capital.

The 100% electric-car allowance has conditions

For qualifying expenditure before April 2027, a new and unused electric car or other zero-emission car can qualify for a 100% first-year allowance.

For a company, the current qualifying deadline is generally expenditure incurred before 1 April 2027.

The allowance does not normally apply to:

• A second-hand electric car
• A hybrid car with emissions above 0g/km
• A car the company merely leases
• A vehicle that does not meet the relevant car and emissions conditions

The acquisition date and the date expenditure is treated as incurred can be important, particularly where an order is placed before the deadline but delivery and unconditional payment obligations arise later.

A rushed purchase made only to obtain tax relief may also be commercially poor. The company should compare the tax timing with the finance cost, depreciation, insurance, expected use and effect on working capital.

HMRC explains the qualifying conditions in its guidance on 100% first-year allowances.

What capital allowances apply to other cars?

Cars do not normally qualify for the Annual Investment Allowance or full expensing.

For cars bought from April 2021, the broad capital-allowance treatment is:

• New and unused zero-emission cars may qualify for the 100% first-year allowance within the qualifying period.
• Second-hand electric cars and new or used cars with CO2 emissions of 50g/km or less normally enter the main-rate pool.
• Cars with CO2 emissions above 50g/km normally enter the special-rate pool.

From April 2026, the main writing-down allowance rate is 14%. The special-rate allowance remains 6%.

These are reducing-balance allowances rather than a deduction of the full cost each year.

For example, a £45,000 car in the special-rate pool may generate a first full-year writing-down allowance of:

£45,000 x 6% = £2,700

The approximate Corporation Tax effect of that deduction would be:

• £513 at 19%
• £675 at 25%

The timing may be adjusted for the length of the accounting period, and the pool continues on a reducing balance.

This is much slower relief than a qualifying 100% first-year allowance.

HMRC's current business-car capital allowance guidance confirms the emissions bands and rates.

Worked example: higher-emission company car

Assume the company provides a car with an original list price of £45,000 and the vehicle falls within the maximum 37% company-car band.

The annual taxable benefit is:

£45,000 x 37% = £16,650

The director's illustrative Income Tax cost would be:

• £3,330 at 20%
• £6,660 at 40%
• £7,492.50 at 45%

The company's Class 1A National Insurance would be:

£16,650 x 15% = £2,497.50

Those annual charges arise while the car is available for private use, subject to the detailed rules and any valid adjustments.

The company may claim deductions for qualifying running costs and capital allowances, but the personal benefit and Class 1A charges can outweigh the tax advantage of company ownership.

For many owner-directors, a personally owned higher-emission car with tax-free business mileage reimbursement will be more efficient than providing the same vehicle as a company car.

That is not automatic. High business mileage, low private mileage, finance terms and the director's tax rate still need to be modelled. However, the 37% benefit percentage is a strong warning that the company-car route may be expensive.

How the personal-car route works

Where the director owns or leases the car personally, the company does not claim capital allowances on the car and does not pay its purchase price.

Instead, the company can reimburse the director for qualifying business journeys.

For 2026/27, the approved mileage rates for cars and vans are:

• 55p per mile for the first 10,000 business miles in the tax year
• 25p per mile for each qualifying business mile above 10,000

The increase from 45p to 55p for the first 10,000 miles applies from 6 April 2026.

The mileage rate is intended to cover more than fuel. It contributes towards the overall cost of using the personal vehicle, including:

• Fuel or electricity
• Insurance
• Servicing
• Repairs
• Tyres
• Vehicle Excise Duty
• Depreciation
• Finance costs

The director cannot claim those costs separately from the company in addition to receiving the approved mileage amount for the same use.

The company can normally deduct a valid mileage reimbursement when calculating its taxable profit. The director can normally receive the approved amount without an Income Tax or National Insurance charge.

HMRC's current mileage and fuel rates confirm the 2026/27 rates.

Worked example: 8,000 business miles in a personal car

Assume a director uses their own car for 8,000 qualifying business miles during 2026/27.

The approved mileage amount is:

8,000 miles x 55p = £4,400

The company can pay £4,400 to the director without Income Tax or National Insurance, provided the journeys qualify and adequate mileage records are maintained.

The company may receive a Corporation Tax deduction for the £4,400 payment.

The illustrative Corporation Tax effect would be:

• £836 at 19%
• £1,100 at 25%

The director remains responsible for buying or leasing the car and paying all running costs.

The £4,400 is therefore not a tax-free profit. It is a contribution towards the commercial cost of providing the vehicle.

The personal-car route becomes more attractive where:

• The director already owns a suitable car
• Business mileage is material
• The car has a high company-car benefit percentage
• The director wants to change cars without involving the company
• The company needs to protect cashflow
• The director accepts the personal finance and depreciation risk

What happens above 10,000 business miles?

The Income Tax approved rate falls to 25p per mile for qualifying miles above 10,000 in the tax year.

For example, 15,000 business miles would produce an approved amount of:

• First 10,000 miles at 55p: £5,500
• Remaining 5,000 miles at 25p: £1,250
• Total approved amount: £6,750

The lower rate above 10,000 miles means the personal-car option does not become increasingly generous without limit.

Businesses should also note that National Insurance mileage rules are not identical to the Income Tax calculation in every respect. Payroll treatment should be checked where payments exceed the Income Tax approved amount.

Which journeys count as business mileage?

The mileage rules apply to qualifying business travel, not every journey made on a working day.

Qualifying journeys may include:

• Travel from the normal workplace to a customer
• Travel between business locations
• Travel to a temporary workplace
• Travel to a supplier, bank or professional meeting where the journey is necessary for the employment duties
• Site visits and inspections

Non-qualifying journeys normally include:

• Home to a permanent workplace
• A permanent workplace to home
• Personal detours
• School runs
• Shopping and social journeys
• Travel that is mainly for personal convenience

Calling home an office does not automatically turn every journey from home into business travel. The director's actual duties, workplace pattern and the temporary-workplace rules must be considered.

A journey should not be reclassified merely because the director answers emails at home or stops at a customer on the way to the office.

HMRC's guidance on ordinary commuting and private travel should be used where the workplace position is uncertain.

What mileage records should the company keep?

The company should retain a contemporaneous mileage log showing:

• Date of travel
• Starting point
• Destination
• Business purpose
• Number of business miles
• Vehicle used
• Amount reimbursed
• Evidence of any passenger claim
• Confirmation that commuting and private mileage were excluded

The log should agree with diaries, customer records and expense payments.

An annual estimate such as "about 8,000 business miles" is not a strong record.

The director should also ensure that the personal motor insurance policy includes the necessary business use. A tax-allowable journey is not automatically covered by a social, domestic and pleasure policy.

What if the company pays less than the approved mileage rate?

The company does not have to pay the full approved rate.

If it pays less, the director may be able to claim Mileage Allowance Relief on the qualifying shortfall. This gives tax relief on the difference. It is not a cash reimbursement of the whole shortfall.

For example, if the approved amount is £4,400 but the company pays £3,200, the potential relief is calculated on the £1,200 difference.

A basic-rate taxpayer's tax reduction may be £240, subject to their circumstances. They do not receive the full £1,200 from HMRC.

HMRC explains the claim in its guidance for employees using their own vehicles for work.

What if the company pays more than the approved amount?

If the company pays more than the tax-free approved amount, the excess is normally taxable and must be dealt with correctly through payroll, benefits reporting or the applicable mileage-payment rules.

The company should not increase the mileage rate informally to cover an expensive car.

If the commercial reimbursement policy exceeds HMRC's approved amount, the tax and National Insurance treatment of the excess should be reviewed before payments are made.

Do not use the 55p rate for a company car

The approved 55p and 25p mileage rates apply when an employee or director uses their own qualifying vehicle for business travel.

They do not apply in the same way when the company owns or leases the car.

For a company car, fuel-only or electricity reimbursement should be based on the relevant rules and evidence. HMRC publishes advisory fuel rates for company cars, including electric rates, and updates them periodically.

Using 55p per mile for a company car can over-reimburse the director because the company is already meeting the ownership and running costs.

HMRC's advisory fuel rate guidance should be checked at the time of payment.

What if the company pays for private fuel?

Private fuel can create a second taxable benefit in addition to the company-car benefit.

For 2026/27, the company-car fuel benefit multiplier is £29,200.

The taxable fuel benefit is broadly the multiplier multiplied by the car's company-car percentage.

For a car in the 37% band:

£29,200 x 37% = £10,804

The director's illustrative Income Tax on that fuel benefit would be:

• £2,160.80 at 20%
• £4,321.60 at 40%
• £4,861.80 at 45%

The company's Class 1A National Insurance would be:

£10,804 x 15% = £1,620.60

This charge can be disproportionate to the actual private fuel provided.

Reimbursing some, but not all, private fuel does not necessarily produce a proportionate reduction. The arrangement should be reviewed and full private-fuel repayment completed within the required time if the company intends to avoid the fuel benefit.

Electricity is subject to specific rules and is not treated in exactly the same way as petrol or diesel for the car fuel benefit. Employer-provided or reimbursed charging for a company electric car can be exempt in circumstances covered by the legislation. The facts and charging arrangement should still be documented.

Buying a car through the company

Where the company buys the car, it owns the asset.

Potential advantages include:

• The company funds the purchase without first paying salary or dividends to the director
• Capital allowances may be available
• The company can normally deduct qualifying running and finance costs
• A new zero-emission car may qualify for the 100% first-year allowance
• The company bears the depreciation and disposal risk
• The director may avoid arranging personal finance

Potential disadvantages include:

• A company-car benefit where private use is available
• Class 1A National Insurance for the company
• Restricted or blocked VAT recovery
• A taxable private-fuel benefit where relevant
• Additional payroll or benefits reporting
• Company cash tied up in a depreciating asset
• Tax consequences when the car is sold or transferred to the director
• A low-emission incentive that may become less generous over the ownership period

The company should record the car on its fixed-asset register, retain the purchase invoice and finance agreement, identify the correct CO2 figure and document when the car was first made available.

Leasing a car through the company

Leasing can reduce the initial cash requirement, but it does not remove the company-car benefit.

If a leased car is available for private use, the benefit is still generally calculated by reference to the car's list price and appropriate percentage, not the monthly lease payment.

The company may normally deduct qualifying lease rentals, subject to the usual business-purpose rules.

For a car with CO2 emissions over 50g/km, a 15% restriction can apply to the deductible lease rental. Broadly, only 85% of the otherwise allowable rental may be deductible.

The restriction does not generally apply to cars at or below the relevant 50g/km threshold.

Lease agreements also need to be examined carefully because:

• Initial rentals can be substantial
• Excess mileage charges may apply
• Maintenance may or may not be included
• Early termination can be expensive
• The company does not own the asset at the end of a standard operating lease
• A finance lease or hire-purchase agreement can have different accounting and tax treatment

A low monthly headline price is not enough to compare the options.

VAT on a company car purchase

VAT recovery on cars is frequently misunderstood.

A VAT-registered business normally cannot reclaim input VAT on the purchase of a car if the car is available for any private use. This is a strict test.

Full recovery may be possible in limited situations where the car is used exclusively for business and is not available for private use, or where it is acquired for certain qualifying activities such as genuine leasing, taxi operation or driving instruction. The evidence needs to support the position.

Keeping the car at the director's home and allowing commuting or other personal use will normally prevent full input VAT recovery on the purchase.

The fact that business use is 90% does not normally mean 90% of the purchase VAT can be reclaimed.

VAT on leased cars and mileage claims

For a qualifying leased car with private use, a VAT-registered business can normally reclaim 50% of the VAT on the lease rental, subject to the usual rules and any partial-exemption restriction.

The 50% block is intended to reflect private use.

VAT on separately supplied maintenance may have different treatment, so invoices and contract terms should be reviewed rather than assuming every charge follows the rental treatment.

Where the company reimburses business mileage in a director's personal car, it may be able to reclaim VAT on the fuel element of the mileage payment. It cannot reclaim VAT on the entire 55p payment.

The company needs:

• A valid mileage record
• Evidence of business journeys
• Suitable VAT fuel receipts
• A supportable fuel element, often based on an accepted rate
• Any necessary partial-exemption adjustment

HMRC's VAT motoring expenses guidance explains the purchase, leasing, fuel and mileage rules.

Used electric cars require a separate calculation

A used electric car can still have a low 4% company-car percentage in 2026/27 because the benefit depends on emissions and list price.

However, two points can reduce the apparent advantage.

First, the benefit normally uses the original list price rather than the used purchase price.

Second, a second-hand electric car does not normally qualify for the 100% first-year capital allowance. It generally enters the main-rate capital-allowance pool, which has a 14% writing-down allowance from April 2026.

Consider a used electric car with:

• Original list price: £50,000
• Company purchase price: £28,000
• Company-car percentage: 4%

The annual benefit is broadly:

£50,000 x 4% = £2,000

The director's tax would be £400 at 20% or £800 at 40%.

The company's Class 1A National Insurance would be:

£2,000 x 15% = £300

The first full-year main-rate writing-down allowance on £28,000 would be approximately:

£28,000 x 14% = £3,920

This may still be attractive, but it is not the same result as buying a new £28,000 electric car that qualifies for immediate 100% relief.

Future electric company-car rates matter

The 4% electric company-car percentage applies for 2026/27.

Under current legislation, the zero-emission percentage is scheduled to rise to:

• 5% in 2027/28
• 7% in 2028/29
• 9% in 2029/30

A car acquired under a three-year or four-year finance agreement should therefore be modelled across the full period rather than using only the first year's tax rate.

Electric company cars can remain attractive despite the scheduled increases, but the annual personal tax and Class 1A National Insurance costs will rise if the list price stays the same.

What about salary sacrifice?

Salary sacrifice can alter the cashflow and employment-tax comparison.

Cars with CO2 emissions of 75g/km or less are subject to specific optional-remuneration rules that can preserve the normal company-car benefit basis in qualifying cases. Higher-emission vehicles can be treated less favourably.

However, salary sacrifice is not simply an accounting journal.

The arrangement should consider:

• A valid change to contractual remuneration
• National Minimum Wage restrictions
• Pensionable pay and other employment benefits
• Maternity, sickness and redundancy calculations
• Finance and early-termination terms
• The company-car benefit
• Payroll and reporting requirements
• What happens when employment ends

Owner-directors should not assume that sacrificing salary automatically produces a better result than a direct company purchase or personal ownership.

The company still needs a commercial reason and sufficient cash

Tax efficiency should not override affordability.

A company may receive tax relief but still weaken its cash position by purchasing a car.

Before committing funds, the company should consider:

• Corporation Tax due
• VAT, PAYE and pension liabilities
• Supplier payments
• Working-capital requirements
• Planned recruitment
• Loan covenants
• Dividend plans
• Emergency reserves
• Expected resale proceeds

Spending £45,000 to obtain a tax deduction is not sensible if the company then needs expensive borrowing to meet ordinary liabilities.

The decision should be included in a cashflow and tax forecast.

Personal ownership also has hidden costs

The personal-car route can look attractive because the mileage reimbursement is tax-free, but the director carries the economic cost.

The director may need to fund the car using:

• Personal savings
• Taxed salary
• Dividends paid from post-Corporation Tax profits
• Personal hire purchase
• Personal contract purchase
• A personal lease

Salary and dividends can carry additional personal tax. A dividend also requires sufficient distributable profits and proper approval.

Personal finance rates may differ from company finance rates. Insurance, deposit requirements, early-settlement charges and mileage limits should be included.

The company-versus-personal comparison should therefore start before the money is extracted, not after it appears in the director's bank account.

Disposal and transfer consequences

If the company owns the car, it receives the sale proceeds and must account for the disposal under the capital-allowance rules.

If the car is transferred or sold to the director, the transaction should take place at an appropriate market value. Selling a company asset to a director at an undervalue can create additional tax, benefit and company-law issues.

The company may also have finance outstanding or restrictions imposed by the lender.

If the director personally owns the car, the director normally receives the disposal proceeds. A private motor car will usually be exempt from Capital Gains Tax, but the position can differ for vehicles that are not ordinary private cars or are used within another business structure.

Expected resale value should be part of the original comparison because it determines who bears the depreciation and who receives the remaining value.

Is a company car more efficient for an electric vehicle?

Often, yes, particularly where all of the following apply:

• The car is fully electric
• It is new and unused
• It is acquired before the current first-year allowance deadline
• The company has taxable profits against which relief can be used
• The company can afford the purchase or lease
• The director is comfortable with the benefit increasing in future years
• The vehicle will be retained for a commercially sensible period
• The financing and insurance terms are competitive

However, the company-car route may be less attractive where:

• The car has a very high list price
• It is second hand and the original list price was much higher than the purchase price
• The company has losses and cannot use the tax relief promptly
• The company needs cash for operations
• The director already owns a suitable personal vehicle
• Business mileage reimbursement would cover a meaningful part of personal running costs
• Finance or lease terms are poor

Electric does not automatically mean company ownership is best.

Is a personal car more efficient for petrol or diesel?

Frequently, especially where the vehicle has a high company-car percentage.

The personal route may be preferable where:

• The car falls within a high emissions band
• Private use is substantial
• The director is a higher-rate or additional-rate taxpayer
• The company would also provide private fuel
• The director already owns the car
• Qualifying business mileage is significant
• The company wants to preserve cash

The decision can be closer for a low-cost, lower-emission car, a car with limited private availability or a director with unusual travel patterns.

The actual model and specification must be checked. Two versions of the same vehicle can have different list prices, emissions figures and company-car percentages.

What if the business is a sole trader?

A sole trader and their business are not separate legal persons. The company-car benefit rules do not apply in the same way because there is no limited company providing an employment benefit to its director.

The relevant choice is usually between:

• Simplified mileage expenses
• Actual business motoring costs plus capital allowances where available

For 2026/27, the simplified mileage rates for cars and goods vehicles are 55p for the first 10,000 business miles and 25p thereafter.

The mileage method replaces claims for the vehicle's purchase and running costs. A sole trader cannot claim simplified mileage for a vehicle if capital allowances or another deduction for that vehicle has already been claimed.

Once the flat-rate method is used for a particular vehicle, it must continue while that vehicle is used in the business.

Under the actual-cost method, private use must be excluded and capital allowances may be restricted to the business proportion.

Sole traders should therefore run a separate mileage-versus-actual-cost comparison. They should not apply a limited-company benefit calculation to themselves.

HMRC provides guidance on simplified vehicle expenses.

Vans are not automatically treated like cars

Cars and vans have different benefit and capital-allowance rules.

However, the label used by a manufacturer, dealer or driver does not determine the tax classification.

Double-cab pickup rules have changed, and many vehicles that owners may describe as commercial can be treated as cars for benefit purposes from the relevant dates.

Before relying on van treatment, confirm:

• Vehicle construction
• Primary suitability
• Payload and specification
• Acquisition or lease date
• Transitional rules
• Actual private use
• Which tax provision is being considered

A vehicle can be classified differently for different legal or tax purposes. Advice based only on the V5 description or a sales brochure may be incomplete.

Common mistakes directors make

Comparing only the monthly payment

A cheaper lease payment does not reveal the company-car benefit, Class 1A National Insurance, VAT recovery or end-of-contract charges.

Using the purchase price for the benefit calculation

Company-car tax normally uses the relevant list price, not the discounted or second-hand purchase price.

Assuming low private mileage means no benefit

Availability for private use can create the charge even where actual private mileage is small.

Treating commuting as business travel

Ordinary travel between home and a permanent workplace is generally private.

Paying 55p per mile for a company car

The 55p rate applies to an employee's own vehicle, not a company-owned or company-leased car.

Claiming full VAT on a company car purchase

Purchase VAT is normally blocked where any private use is available.

Applying the 100% electric-car allowance to a used car

The current 100% first-year allowance generally requires a new and unused zero-emission car.

Ignoring the electric-car rate increases

A four-year ownership decision should not be based solely on the 4% rate for 2026/27.

Providing private fuel without calculating the benefit

The fuel benefit can exceed the actual private-fuel cost.

Keeping no mileage log

Bank payments and calendar entries alone may not establish the purpose and distance of each journey.

Ignoring cashflow

Immediate tax relief does not compensate for leaving the company unable to meet VAT, payroll or suppliers.

Forgetting who receives the resale value

The company receives proceeds from a company-owned car. The director receives proceeds from a personally owned car.

A practical comparison process

Before buying or leasing the car, gather the following information.

Vehicle information

• Exact make, model and derivative
• New or second hand
• Cash price
• Original list price
• Taxable accessories

Cost and tax modelling

Calculate at least:

• Company purchase or lease payments
• Capital allowances or rental deductions
• Corporation Tax effect
• Company-car benefit for every year of ownership
• Director's Income Tax
• Employer's Class 1A National Insurance
• Fuel benefit where relevant
• VAT recovery
• Mileage reimbursement under the personal route
• Finance interest
• Running costs
• Expected disposal proceeds
• Net cash cost to the company and director

The comparison should cover the full expected ownership or lease period, not only year one.

When should the calculation be reviewed?

Review the position:

• Before signing an order or finance agreement
• Before the company's accounting year-end
• Before 1 April 2027 if relying on the current zero-emission first-year allowance
• When the director's tax band changes
• When expected mileage changes materially
• When a permanent workplace changes
• When the company becomes VAT registered
• When the car is replaced, returned or sold
• When private fuel or charging arrangements change
• When another employee begins using the car

A calculation prepared after the vehicle has been acquired may identify the tax cost, but it may be too late to change the ownership structure or finance agreement efficiently.

Frequently asked questions

Is an electric company car always more tax-efficient than a personal car?

No.

The 4% benefit percentage and potential 100% first-year allowance make a new electric company car attractive in many cases. However, the list price, business mileage, company profits, finance terms, future rate increases and cashflow must still be compared with personal ownership and mileage reimbursement.

Can my company buy my existing personal car from me?

Potentially, but the transaction should be at market value and properly documented.

The company-car benefit may begin once the company owns the car and makes it available for private use. The company will not normally obtain a 100% first-year allowance on a second-hand electric car. VAT, finance and insurance also need review.

Can the company pay the deposit on my personal car?

Not as a tax-free business expense merely because the car will be used for work.

The payment may be salary, a benefit, a loan to the director or another form of extraction depending on the facts. Personal ownership is normally supported through valid mileage reimbursement rather than the company paying personal acquisition costs.

Can I claim 55p per mile in an electric personal car?

Yes, if you are an employee or director using your own qualifying car for genuine business journeys. The approved rate is not reduced because the vehicle is electric.

Can the company reclaim VAT on the 55p mileage payment?

Not on the full 55p.

A VAT-registered company may be able to reclaim VAT on the fuel element of qualifying business mileage, supported by suitable VAT receipts and records. The calculation and partial-exemption position should be checked.

Does the 55p rate apply to commuting?

No. Ordinary commuting to a permanent workplace is generally private travel.

Does a company car avoid the need to take dividends?

The company can acquire or lease the car without first paying the director enough salary or dividends to fund a personal purchase. However, the director may then face company-car tax, and the company pays Class 1A National Insurance and the vehicle costs.

Is a used electric company car tax-efficient?

It can be, because the benefit percentage remains low. However, the benefit uses the original list price and the company normally receives writing-down allowances rather than the 100% first-year allowance.

Can a company car be business-only if I keep it at home?

Possibly in exceptional circumstances, but the evidence threshold is high. Private use must be prohibited and there must be no actual private use. Ordinary commuting is private use for company-car purposes. A car regularly kept at an owner-director's home is unlikely to qualify as a pool car.

Does the company-car benefit depend on how many private miles I drive?

Usually not. The normal calculation is based on the list price, appropriate percentage and period of availability, rather than actual private mileage.

Can I reduce the benefit by paying the company?

Qualifying capital contributions and required payments for private use can reduce the benefit under specific rules. The agreement, timing and limits must be checked. An informal transfer at the end of the year may not produce the intended result.

What happens if the car is unavailable?

The benefit may be reduced where the car is genuinely unavailable for at least 30 consecutive days and the detailed conditions are met. A car parked but still available to the director is not necessarily unavailable for tax purposes.

Is leasing better than buying?

Not automatically.

Leasing can protect cashflow and allow partial VAT recovery on qualifying rentals, but the company does not normally receive capital allowances, the company-car benefit still applies, and a 15% rental restriction can affect cars above 50g/km.

Should the company pay for private petrol or diesel?

The fuel benefit can be expensive and should be calculated before the company provides private fuel. For many directors, paying personally for private fuel or fully reimbursing the company produces a better result.

Can Employment Allowance cover the Class 1A charge?

Employment Allowance does not normally reduce Class 1A National Insurance on benefits in kind. The Class 1A cost should be included separately in the vehicle comparison.

The practical answer for 2026/27

The most likely outcomes are:

A new fully electric car

Company ownership or leasing may be highly competitive because the benefit percentage is 4%. A qualifying company purchase before the current deadline may also obtain a 100% first-year capital allowance.

A used electric car

Company ownership can still be efficient, but the original list price and slower 14% writing-down allowance must be considered.

A higher-emission petrol or diesel car

Personal ownership with business mileage reimbursement is often more efficient, particularly for a higher-rate taxpayer. The company-car and fuel benefits can be substantial.

A car already owned by the director

Keeping it personally and claiming valid business mileage may be simpler and more economical than transferring it to the company.

High business mileage

The personal route benefits from the new 55p rate on the first 10,000 miles, although the rate falls to 25p above that level.

A cash-constrained company

Personal ownership may protect company working capital, but the director must be able to fund the vehicle personally.

These are starting points, not universal conclusions.
