1. What is Company Car Tax?

Company car tax is a form of taxation levied on employees who are provided with a car by their employer for both work and personal use. The tax is calculated based on the car’s value, its emissions, and the fuel type. It is considered a benefit-in-kind (BIK), meaning it is treated as income and taxed accordingly.

The amount of company car tax you pay depends on several factors, including:

  • The car’s CO2 emissions: Cars with lower emissions attract lower tax rates.

  • The car’s list price: The higher the list price, the higher the tax liability.

  • The fuel type: Electric cars may have lower taxes compared to petrol or diesel vehicles.

Employers must report company car benefits on a P11D form, and employees will then see the tax added to their income tax. If you’re an employee using a company car, you’ll need to factor in this tax when calculating your overall tax liability.

Understanding company car tax UK is essential to avoid unexpected bills and ensure that you comply with tax regulations.

2. How Does Company Car Work?

A company car is a vehicle provided by an employer for an employee’s use, primarily for business purposes, but often also for personal use. The main purpose of a company car is to help employees carry out their work-related duties, such as commuting to meetings or transporting goods.

The process works by the employer purchasing or leasing the car, and the employee then has access to it for their personal use as well. The tax implications arise because the car is not solely used for business but also for personal reasons. This makes it a taxable benefit.

To determine the tax code for company cars, the value of the car, its CO2 emissions, and the amount of private use are considered. The more expensive and polluting the car, the higher the tax burden will be.

Employees who have a company car may also be offered additional benefits, such as insurance and maintenance coverage, which are included as part of the overall benefits package.

3. Taxation of Company Cars

Company car tax UK is based on a complex system known as the Benefit-in-Kind (BIK) tax. The amount of tax you pay depends on the car’s emissions, list price, fuel type, and the level of personal use. The BIK tax is calculated using the following key factors:

1. CO2 Emissions

The CO2 emissions of a car play a significant role in determining the amount of tax you will pay. Cars with lower emissions attract a lower BIK tax rate. For instance, electric cars tend to have lower emissions and can benefit from reduced taxes.

2. List Price

The list price of the car, including any optional extras, is used to calculate the base value of the car for tax purposes. A higher list price increases the amount of tax owed.

3. Fuel Type

The fuel type of the vehicle also impacts the tax rate. Electric and hybrid cars typically have lower rates than petrol or diesel cars. This is in line with the UK government’s focus on reducing carbon emissions.

4. Personal Use

The level of personal use also influences the tax rate. If the car is used primarily for personal use, the tax liability will be higher. However, if it’s only used for business purposes, the tax liability may be reduced.

Understanding how these factors interact will help both employees and employers make informed decisions about company car use and taxation.

4. How to Calculate Company Car Tax

Calculating company car tax UK involves several steps. Here’s a basic guide to help you understand how the process works:

Step 1: Identify the car’s list price

The first step is determining the car’s list price, which includes the cost of the car, plus any optional extras (such as a sunroof or advanced safety features).

Step 2: Check the CO2 emissions

The next step is identifying the car’s CO2 emissions. This will determine the tax band for the vehicle. Lower emissions mean a lower BIK rate.

Step 3: Determine the fuel type

The fuel type of the vehicle (electric, petrol, diesel, hybrid) affects the BIK tax rate. Electric cars, for example, typically attract a lower rate than petrol or diesel cars.

Step 4: Personal use factor

If the car is used for personal reasons, you must calculate the percentage of private use. The more the car is used for personal purposes, the higher the tax will be.

Once these factors are identified, the tax rate is applied to the list price of the car, and the appropriate BIK tax is calculated.

5. Company Car Benefits

A company car offers various benefits for both employees and employers. These benefits include:

  • Convenience: Employees have access to a vehicle for both business and personal use.

  • Cost savings: Employees may save on personal vehicle expenses like maintenance and insurance, as these are typically covered by the employer.

  • Tax efficiency: For employers, providing a company car can be a tax-efficient way to offer benefits to employees.

However, these benefits come with the responsibility of company car tax. The more expensive or polluting the vehicle, the higher the tax. It’s important to weigh the benefits against the potential tax burden.

6. Income Tax on Company Car

Income tax on company cars is based on the value of the car and its benefits. When you receive a company car, the value of the benefit is added to your income for tax purposes. The amount of tax you pay depends on several factors, including the car’s list price, emissions, and how much you use the car for personal purposes.

If you have a company car, you must report the benefit on your self-assessment tax return. If the company car is used primarily for personal reasons, it could significantly increase your income tax bill.

Understanding how income tax on company cars works will help you make informed decisions regarding your car benefits and tax liabilities.

7. VAT on Company Cars

VAT on company cars in the UK can be complicated. In most cases, VAT cannot be reclaimed on company cars unless they are used solely for business purposes. However, if the car is used for both business and personal use, you may only be able to reclaim a portion of the VAT.

For instance, if you use the car for business purposes 70% of the time and for personal purposes 30% of the time, you may be able to reclaim 70% of the VAT on the car. The rules around VAT on company cars are specific, so it’s essential to consult with an experienced VAT accountant to ensure compliance.

8. What to Do if You Have a Company Car

If you’re assigned a company car, it’s important to keep accurate records of your use. This includes keeping track of both business and personal mileage. You’ll need this information to accurately report the company car benefits on your self-assessment tax return.

Additionally, be sure to review your tax code for company car use to ensure the proper amount of tax is being deducted from your income. If you’re unsure about your tax code or need assistance, consulting a professional tax accountant can help you avoid mistakes and optimize your tax position.

9. Company Car Tax and Small Business Owners

For small business owners, providing a company car to employees can be a useful incentive. However, it’s essential to understand how company car tax UK works for small businesses. Small business accountants can help navigate the tax rules and ensure compliance.

For small businesses, offering company cars can also be a way to attract and retain employees, but it’s important to consider the long-term tax implications. A professional accountant can help determine the best course of action, whether that’s offering a company car, a car allowance, or alternative benefits.

10. Alternatives to Company Cars

If the tax burden of a company car seems too high, there are alternatives. For instance, a car allowance can provide employees with the flexibility to choose their own vehicle without the tax implications of a company car. Additionally, using personal cars for business purposes can be an option for some employees.

Employers can also consider offering other benefits that don’t carry the same tax burden, such as contributions to public transportation or cycling schemes.

11. Corporate Tax on Company Cars

The corporate tax implications of company cars are significant. Providing company cars can impact your business’s corporate tax filings, as the cost of the car and its associated benefits may be deductible. However, the car’s list price, emissions, and fuel type must be taken into account when claiming deductions.

Corporation tax accountants can assist with navigating the complexities of claiming tax relief on company cars and ensuring your business stays compliant with HMRC.

12. How to Avoid Taxation Pitfalls

There are several common mistakes businesses and employees make when dealing with company car tax UK. These include failing to accurately report the car’s value, not tracking personal use, or misclassifying the car’s emissions.

Consulting with a professional, such as a chartered accountant Berkshire, can help you avoid these pitfalls and ensure that you’re maximizing any potential tax savings.
