Can My Limited Company Pay for My Car? (UK 2026 Guide)
If you run a limited company, you’ve probably asked:
Can my limited company pay for my car?
The short answer is:
Yes — but how it does so makes a huge difference to the tax outcome.
In many cases, putting a car through a limited company can create significant tax charges. In other cases, it can be efficient.
In this guide, we explain:
- The different ways a company can pay for a car
- Company car tax rules in 2026
- Benefit-in-kind (BIK) implications
- Electric vehicle advantages
- Mileage claim alternatives
- What is usually most tax-efficient
The Three Main Ways a Limited Company Can Pay for a Car
Your company can cover your car in one of three ways:
-
The company buys or leases the car
-
You personally own the car and claim mileage
-
The company reimburses specific business expenses
Each has very different tax consequences.
Option 1: The Company Buys the Car
Your limited company can purchase a car in its own name.
However, if you use that car personally (including commuting), it becomes a company car and triggers:
- Benefit-in-kind (BIK) tax for you
- Employer’s National Insurance for the company
This is where many directors are caught out.
What Is Company Car Benefit-in-Kind Tax?
If a company provides a car for private use, HMRC treats it as a taxable benefit.
You personally pay Income Tax on the benefit.
The company pays Class 1A National Insurance (currently 13.8%) on the value of that benefit.
The amount of BIK depends on:
- The car’s list price
- Its CO₂ emissions
- The fuel type
This means petrol and diesel cars can be very expensive tax-wise.
Example: Petrol Company Car
Assume:
- List price: £40,000
- BIK percentage: 30% (illustrative for higher-emission vehicles)
Taxable benefit:
£40,000 × 30% = £12,000
If you are a higher-rate taxpayer (40%):
Personal tax:
£12,000 × 40% = £4,800 per year
The company also pays:
£12,000 × 13.8% = £1,656 per year in Employer NIC
This can make traditional company cars inefficient.
Electric Cars: A Major Exception
Fully electric vehicles are treated much more favourably.
For 2026/27, the BIK rate for electric cars remains significantly lower than petrol or diesel vehicles (though it has gradually increased from earlier ultra-low levels).
Because the BIK percentage is much lower:
- Your personal tax bill is significantly reduced
- Employer NIC is also lower
This is why electric vehicles are often the most tax-efficient option if buying through a company.
Can the Company Claim Corporation Tax Relief?
Yes.
If the company buys the car, it may claim capital allowances.
The amount depends on:
- Whether the car is electric
- Its CO₂ emissions
Fully electric cars typically qualify for more favourable capital allowance treatment compared to higher-emission vehicles.
Leasing payments are also generally deductible for Corporation Tax (subject to emission-based restrictions).
Option 2: You Own the Car Personally and Claim Mileage
This is often the most tax-efficient option for many directors.
If you personally own the car, the company can reimburse you using HMRC’s approved mileage rates:
- 45p per mile for the first 10,000 business miles per tax year
- 25p per mile thereafter
These rates cover:
- Fuel
- Wear and tear
- Insurance
- Servicing
- Depreciation
There is:
- No Benefit-in-Kind tax
- No Employer NIC
-
No additional reporting
The company claims the mileage as a deductible expense.
For many small business owners, this is simpler and more efficient than running a petrol or diesel company car.
Example: Mileage Claim
If you drive 8,000 business miles:
8,000 × 45p = £3,600
The company pays you £3,600 tax-free.
The company deducts £3,600 from its profits for Corporation Tax purposes.
No personal tax arises.
Option 3: The Company Reimburses Fuel Only
If the company pays for fuel in a company car used privately, an additional fuel benefit charge applies.
This is often very expensive.
In most cases, it is more tax-efficient for directors to:
- Pay for private fuel personally
- Reimburse the company for private mileage
Fuel benefit charges are frequently misunderstood and can create large unexpected tax bills.
What About Leasing a Car Through the Company?
Leasing works similarly to buying from a tax perspective.
If the car is available for private use:
- BIK applies
- Employer NIC applies
The company can deduct lease payments for Corporation Tax, although high-emission vehicles may have restrictions.
Electric lease vehicles remain significantly more attractive.
What If the Car Is Only Used for Business?
If a car is genuinely:
- Not available for private use
- Kept at business premises
- Restricted by contract
BIK may not apply.
However, HMRC’s definition of “private use” includes commuting.
For most directors, avoiding private use entirely is difficult in practice.
Should I Put My Car Through My Limited Company?
It depends on:
- The type of car
- How many business miles you drive
- Your personal tax rate
- Whether it is electric
- Whether you already own the car
General guidance:
Petrol/diesel company cars are often tax-inefficient.
Electric company cars are often tax-efficient.
Personally owned cars with mileage claims are often the simplest option.
What About Buying the Car Personally and Charging the Company?
If you already own a car personally:
- The company cannot simply “pay for it” without tax consequences.
- Mileage claims are usually the correct route.
Trying to run personal car costs directly through the company without proper structure can create tax issues.
Common Mistakes Directors Make
We often see:
- Buying a petrol car through the company without understanding BIK
- Paying for private fuel through the company
- Not tracking business mileage
- Assuming “it’s a business expense” means no personal tax applies
- Ignoring Employer NIC on benefits
Car tax is one of the most misunderstood areas for small company directors.

Final Answer: Can Your Limited Company Pay for Your Car?
Yes — your limited company can pay for your car.
However:
- If it is a company car used privately, Benefit-in-Kind tax applies.
- Petrol and diesel cars are often expensive tax-wise.
- Electric vehicles are significantly more tax-efficient.
