What is the Company Car Tax on Electric Cars?

A lot of us do not know how car tax works. So before signing up for and choosing a company car, you need to do your homework because a poor choice can cost you thousands over the years that you’re using the car.

If you are a small business owner, contractor, or freelancer looking to use company electric cars, this article is specifically tailored for you. You will learn how company car tax on electric car works, and how to calculate your car tax with a calculator so you can be tax-efficient and save more money.

Let’s start with the basics.

What is Company Car Tax?

Simply put, a company car tax is payable to anyone with a company car that can be used for business and personal purposes. You pay tax on your company car’s value, which depends on its cost and the fuel it uses.

It doesn’t matter if you spend 5,000 personal miles or 5,000 business miles a year, or a week. Whatever the ratio is, if there’s a personal mileage allowed in that car, and if your insurance allowed it for personal use, you will be paying tax. 

The rules state that the lower the CO2 emissions, the more favourable the capital allowances rates will be.

The car’s value can be reduced if:

  • you’re using it part-time
  • your company provided it to you on a lease
  • its CO2 emissions are low

A separate tax will be payable if the employer pays the fuel for your car’s personal use.

CO2 Emissions Figure

The first thing you need to determine is the CO2 Emissions Figure, which is equivalent to the amount of CO2 your car emits. Non “Euro 6” diesel cars pay a 4% additional tax surcharge compared to petrol cars.

This is very important when looking for cars because the lower the CO2 emissions, the lower the tax bond for that car would be. One of the benefits of purchasing an electric car is the tax incentives you get due to the very low CO2 emissions.

Benefit in Kind

A Benefit in Kind or BiK is a non-cash benefit with a monetary value provided to the employee. These benefits might also be referred to as national pay, fringe benefits, or perks. The benefits have monetary value, so they must be treated as taxable income. 

P11D is the form your employer submits which contains the Benefit in Kind.

These non-cash benefits of monetary value could be private medical insurance, company car, gym membership, etc., where, instead of paying you money, they can give you a benefit.

BiK Bands or Value

The BiK band is determined by the car CO2 emissions figure. Add 4% to the % figure to non “Euro 6” diesel cars. E.g. a Petrol car with 101 g/km of CO2 is in the 25% band for the tax year 2021/2022.

Latest Car Reviews – Company Electric Vehicles

The pure electric vehicle (EV) was not subject to Benefit in Kind tax for 2020/2021, but for the 2021/2022 financial year, they attract a BiK rate of 1% and just 2% in 2022/2023.

So if you have an electric car right now, you’d be paying as little as a hundred for the car tax at the end of the year.

This means company car drivers who choose an EV will save thousands compared to the driver of comparable petrol, diesel, or PHEV.

Like the majority of tax systems, BiK rates change with the changing budget announcement. Usually, taxation rates may increase over time. But the government has been promoting electric vehicles and tweaking the system to favour the purchase and use of such cars.

Your Income Tax Rate

The P11D value of the car will be added to whatever your earnings are in order to calculate your tax band. If you go into the next band even slightly, you will pay a higher level of tax on the whole thing.

What you also have to consider are the cost of the company car and the percentage you get from the BiK band. 

Say for example you have a £30.000 car and a 25% band, which is £7,500 in what you currently earn, that’s going to push you into the next income tax band. You must look into that because if it pushes you even £1, you will be paying 40% on that car then.

A lot of people get a company car towards that next tax band and putting in £10,000 to £20,000 on top might be the thing that cost you a lot of money.

Calculate Your Tax Rate with a Car Tax Calculator

There’s a government website by the HM Revenue and Customs (HMRC) with an online form where you can input all the bits of numbers and calculate everything for you. Just use the HM Revenue and Customs (HMRC) CCCF Calculator.

Another option is the comcar.co.uk company car tax calculator. The car tax calculator works pretty much in the same way as the HRMC tax calculator but it gives you a little bit more details like a summary of the tax components, the electric battery range of your car, and some vehicle details.

If you want to do it manually, the formula for calculating your Co Car Tax is based on the HM Revenue and Customs CCCF Calculator:

Car Cost x BiK Band % = BiK  Value x Your Income Tax Level

For instance, if you have a salary that sets you under a 20% tax back while your electric car gets a 25% BiK rate, you’ll have to pay 20% of 25% of its value.

  • 25 % of £20,000 car = £5,000
  • 20% of £5,000 BiK rate = £1,000

Another Example:

  • 28,000 car +  £2,000 optional extras =  £30,000 Car Cost
  • Given BiK Band % = 20%

BiK Value is (Car Cost x BiK Band %) = £7,500

Tax on £7,500:

  • At 20% =  £1,500 per anum
  • At 40% =  £3,000 per anum
  • At 45% – £ 3,375 per anum

Think about that and other extras you have. If your workplace pays for your gym membership or private medical insurance, that’s on top of your BiK Band % value

If you do earn quite a lot of money, watch out for stealth tax on anything over £100,000. Between £100,000 and  £123,000, the government removes your tax allowance so all the different bands move forward.

You start paying electric vehicle company car tax the moment you earn a pound go through all the different tax bands and reach the 40% band earlier. So it’s important to remember this because it will have a huge effect on the amount you take home.

What About VAT?

You can claim 100% of the VAT on a new car provided that it is used 100% for business purposes only – no personal use at all. If there is any personal use, even just one mile, then you will not be able to claim back the VAT at all.

If you are leasing the car, you can claim back 100% of the VAT if there is no personal use. The good news here is that if there is personal use, then you can still claim back 50% of the VAT.

Electric Car Tax Updates

Updates to the UK’s electric car tax reflect continuous initiatives to encourage the use of electric vehicles (EVs) and advance environmentally friendly modes of transportation. To address environmental concerns and facilitate the switch to electric vehicles, several significant adjustments and modifications have been made. Here are a few noteworthy adjustments to the tax on electric cars:

Tax Rates on Benefits-in-Kind (BIK):

When it comes to taxes, internal combustion engine (ICE) cars are not as fortunate as electric vehicles. Electric corporate cars continue to have lower benefit-in-kind (BIK) tax rates than their ICE equivalents, demonstrating the government’s commitment to promoting the use of zero-emission vehicles.

Extension of Zero BIK Tax Rate:

The 0% BIK tax rate for electric vehicles has been extended by the government until 2025. Employers and employees can save a substantial amount of money on taxes thanks to this incentive, which is valid for both new and used electric corporate cars.

Rewards & Grants for Electric Vehicles:

To encourage the use of electric vehicles, government subsidies and incentives are still available. This includes the Plug-In Car Grant, which offers financial benefits to buyers of qualified electric vehicles, thereby increasing the accessibility and affordability of these vehicles for end users.

Extension of the Infrastructure for Charging:

The goal of ongoing infrastructure investments in charging is to improve electric vehicle charging accessibility and convenience. To keep up with the increasing number of electric vehicles on the road, the government is encouraging the construction of workplace charging stations and supporting the growth of public charging networks.

Tax Benefits for Infrastructure Installation Charges:

Companies that construct workplace charging stations or other charging infrastructure may qualify for tax breaks or other incentives that cover installation expenses. This program encourages companies to assist staff members and clients in adopting electric vehicles.

Requirements for Company Car Tax Reporting:

Employers must appropriately submit to HM Revenue and Customs (HMRC) their corporate car tax liability for electric vehicles. Transparency and respect for tax laws are ensured by meeting reporting obligations.

Additional Pointers

For many years, when only two car options were petrol and or diesel, the perks of a company car through your limited company were long gone and quite taxing. 

Since the advent of hybrid plug-in electric vehicles and electric company cars, the UK government is now encouraging motorists to get one through generous car tax breaks and even grants.

You can get a grant up to the maximum of £3,000 for a plugin low-emission vehicle. Read The OLEV Government Grant for more details on this.

Going back to taxes, look and prepare for ever-changing goalposts – watch the budget occasionally as car tax changes regularly, and almost always for the worst.
