Buying a Car Through Your Limited Company: 4 Things You Need to Know

When your company buys a piece of equipment or a business car, you can deduct part, or all, of the cost from your business’s taxable profits. 

How much of the cost of the purchase you can deduct from your profit is dependent on several factors. The main points to consider are how you finance the purchase, how you use the vehicle and how environmentally friendly the vehicle is. 

Buying a car with a limited company, can be a great way to save on your tax bill. However, it is essential that you understand everything involved before you do. 

These are 4 important points you need to know about purchasing a vehicle through a limited company. 

How have you financed the purchase? 

How you pay for the new business car will affect the tax rate you have to pay on it. 

If your company takes out a loan to purchase the vehicle, or it is purchased on hire-purchase, you will only be able to deduct the interest payments as a business expense. You will not be able to deduct the loan itself as a business expense.  

If you lease a vehicle for use by the company, but you do not buy it outright, you will be able to claim the monthly payments as a business expense. 

Other maintenance costs involved with owning a business car, such as insurance, can be claimed as business expenses for Corporation Tax.

Will the vehicle be used for purely business purposes? 

If your car is used solely for business-related purposes, you will be allowed to claim VAT back on the purchase. 

If your company vehicle is used for personal purposes outside of the business, this is considered a Benefit-In-Kind (BIK). A benefit-in-kind is anything HMRC considers to be a benefit or a perk on top of your salary. Your business will be taxed on benefits-in-kind.

To reclaim the VAT on your company car you will need to be able to prove to HMRC that the vehicle is not and cannot be used by you or your employees for personal reasons. For example, do you have a company car that is always kept on stand-by at the dental practice for use by the business? That can be considered an exemption. 

HMRC does not consider your normal commute to and from work to be a business use, so you will not be able to claim VAT on your vehicle if it is primarily used for commuting. 

You can also claim back VAT on vehicles which are used as part of your employee’s routine duties. For instance, vehicles used for teaching people how to drive, taxis and vehicles which are primarily loaned in self-drive schemes.

Is your company vehicle environmentally-friendly? 

How much tax you pay on your company vehicle is also dependent on the CO2 emissions it produces and the date on which you bought it. This applies to both the tax rate of any benefits-in-kind and the capital allowances you can claim on the cost of buying the vehicle. 

You can find out more about the difference between different emissions and dates of purchase, and how they affect the capital allowance rate you pay on the website here.

For the most part, the more CO2 emissions produced by your company car, the more tax you will have to pay. 

However, it is important to remember that the criteria also change according to how old your car is. The newer your car is, the greener it will need to be if you want to claim back on tax.

For instance, this is a table from the Government’s page on business cars: 

Cars bought from April 2021

Description of carWhat you can claim
New and unused, CO2 emissions are 0g/km (or car is electric)First year allowances
New and unused, CO2 emissions are between 1g/km and 50g/kmMain rate allowances
Second hand, CO2 emissions are between 1g/km and 50g/km (or car is electric)Main rate allowances
New or second hand, CO2 emissions are above 50g/kmSpecial rate allowances

Compare this with the rates for cars bought between April 2009 and April 2013:

Cars bought between April 2009 and April 2013

Description of carWhat you can claim
New and unused, CO2 emissions are 110g/km or less (or car is electric)First year allowances
New and unused, CO2 emissions are between 110g/km and 160g/kmMain rate allowances
Second hand, CO2 emissions are 160g/km or less (or car is electric)Main rate allowances
New or second hand, CO2 emissions above 160g/kmSpecial rate allowances

Vehicles which meet the criteria for First-Year Allowances can have 100% of their cost of purchase deducted from the business’s taxable profits. This is intended to encourage British businesses to go green and purchase environmentally-friendly assets. 

The Main Rate pool allows you to claim 18% of the cost of the purchase against your taxable profit. 

The Special Rate band allows you to claim just 6% of the cost of the purchase. This is intended to discourage British businesses from buying environmentally-unfriendly assets. 

You can calculate the tax band for your company car, according to its CO2 emissions, fuel consumption and date of purchase on the website here.

How much tax do you need to pay on the fuel for your business car?

If your company owns a business car, you may be required to pay tax on the fuel required. 

Again, how much tax you pay on the fuel will depend on the CO2 emissions and whether it is used for private or solely for business purposes. 

If your business car is only used for business purposes then you will need to be able to prove this to HMRC. This is one of the reasons why it is so important to keep detailed records like submitted travel expenses and mileage reports. You can use these to show HMRC that all of the consumed fuel was used for business purposes, and not personal use. 

If you cannot prove this, or you have indeed used the car (and thus the fuel) for personal reasons, this will be considered a benefit-in-kind. Therefore, you will need to pay tax on the benefit-in-kind fuel usage. 

If you can show HMRC that the vehicle has not been used for anything other than company business, you will not need to pay any additional benefit-in-kind tax. You will also be able to reclaim the full VAT amount on the fuel. 

You will also not have to pay VAT on the fuel usage if the vehicle is used in certain other circumstances. For instance, cars used for business journeys such as those that are part of the employee’s normal routines like a tradesperson travelling to appointments (this does not include your normal commute to work), or one of your associates travelling to a temporary place of work. 

You can find out more about exemptions for tax payments on fuel on the website here.

Should you buy a business car via your dental practice? 

So, are you better off purchasing a business car through your limited company or privately? 

Let’s take a look at an example: 

Harry is a dental practice owner who owns a limited company who wants to buy a business car at around £40,000.

Buying the car himself:

Harry can declare a £40,000 dividend from his limited company and use that to purchase a car. Harry has to pay 32.5% as a higher-rate taxpayer. This comes out to £13,000 in income tax he has to pay.

Buying the car via a limited company:

Harry could instead buy the care via his limited company. Since there is no dividend declared, there’s no added income tax. Harry’s capital allowances will also allow him to claim back £7,600 in corporation tax. In the current tax year, the benefits-in-kind tax rate is only 1%, meaning the tax on them will be minimal.

This means that Harry is better off to the tune of £20,600 by purchasing his business car through his limited company.
