How to Run Your Car in a Tax-Effective Way

As a business owner, managing personal vehicle expenses through your company is a common practice. However, the best approach depends on your financial situation and how often you use your vehicle for car tax business purposes. There are two primary methods for handling these expenses: personal ownership with mileage claims and company ownership with a benefit-in-kind (BIK) tax charge. Each has its advantages and drawbacks. But there’s also an alternative option — using an LLP or partnership, which can often be the most tax-efficient approach. Here’s a breakdown of each method.

Option I: Personal Ownership with Mileage Claim

This is one of the simplest methods. With this approach, you own the vehicle personally and charge your company for the business miles driven. Here’s how it works:

• Tax-Free Mileage Reimbursement: HMRC offers an approved mileage rate of 45p per mile. This rate is intended to cover your vehicle’s operating costs, including maintenance, insurance, servicing, wear and tear, and depreciation.
• Administrative Requirements: The main downside is the administrative burden. You must keep detailed mileage logs for each business trip, including:
  • Start and end points
  • Total miles driven
  • Purpose of the trip
• Limitations for High-Value Vehicles: While this approach works well for regular, low-cost vehicles, it may not be ideal for high-value cars like a Ferrari. The mileage rate is the same regardless of whether you’re driving a Ford Fiesta or a luxury vehicle, meaning you may not fully recover all the costs associated with owning and maintaining an expensive car. The method doesn’t cover all the expenses associated with high-value cars, such as expensive insurance or high servicing costs.

Summary:

• Simple to implement
• Mileage reimbursed at 45p per mile
• Administrative records required
• Not ideal for high-value vehicles

Option II: Company Ownership with Benefit-in-Kind

Another common approach is to have your company own the vehicle, using it for both business and personal purposes. This method is subject to a benefit-in-kind (BIK) tax charge, which is determined based on the vehicle’s CO2 emissions and list price when new.

• Benefit-in-Kind Charge: The BIK charge can be as high as 37% of the car’s original list price, depending on the vehicle’s emissions. If the car is purchased second-hand or has depreciated over time, the BIK tax is still based on the original list price.
• Example: If your company owns a Land Cruiser valued at £80,000 with CO2 emissions over 215g/km, you could face a BIK charge of £29,600. The Director would then pay income tax on this charge (£11,840), plus National Insurance (£3,590). On top of this, the company would have to pay employer National Insurance (£4,085). The total tax cost could amount to £19,515 annually.
• Higher Costs for High Emission Vehicles: The BIK charge can quickly become expensive, especially if you’re driving a high-emission vehicle. This makes the method less tax-efficient for larger vehicles with higher CO2 emissions.

Summary:

• Company owns the car
• BIK tax based on original list price and emissions
• Expensive for high-emission vehicles
• High tax cost can offset the savings

A More Tax-Efficient Alternative: Using an LLP or Partnership

If you’re looking for a more tax-efficient way to handle your vehicle expenses, consider running your car through a partnership or LLP (Limited Liability Partnership). This method can offer significant savings, especially for those using their vehicles for business purposes.

• No BIK Charge: Unlike the company ownership method, there is no BIK charge when you use a partnership or LLP to own your vehicle. The car is considered an asset of the partnership, and it can be used privately without attracting a tax charge.
• Tax Relief for Business Use: The best part of using an LLP is that you can offset business-related vehicle expenses such as fuel, insurance, maintenance, and servicing against the income generated by the partnership. This applies as long as the partnership has some commercial substance (e.g., a legitimate business like a consultancy).
• Business Use Percentage: Typically, you can claim up to 75%-80% of your vehicle’s running costs if a large proportion of its use is for business purposes. This means you can achieve full tax relief at the higher rate of 40% on these costs. Over time, this approach can save you thousands of pounds.

Example: Consider a BMW worth £40,000 with CO2 emissions of 160g/km and an annual mileage of 20,000 miles, with 75% of the usage being business-related. By running your car through an LLP, you could save significant amounts compared to the personal ownership or company ownership methods.

Summary:

• No BIK charge
• Business-related costs are tax-deductible
• Potential tax relief up to 40% on vehicle expenses
• Ideal for those with a legitimate business or commercial activity

Example Comparison of Costs (3-Year Summary)

Let’s look at a comparison of costs over three years for a BMW costing £40,000 with CO2 emissions of 160g/km. The car’s annual mileage is 20,000 miles, with 5,000 miles officially logged as business miles. Assuming 75% of the total usage is for business purposes, here’s how the costs compare across the three options:

Costs	Limited Company	Personal Ownership	LLP
Motor Expenses	£20,180	£22,012	£39,668
Benefit-in-Kind (Company)	£7,392	£9,000	£9,000
Benefit-in-Kind (Individual)	£22,012	£40,000	£40,000
Total Costs	£49,584	£9,916	£32,400
Tax Relief	£9,916	£20,180	£26,481
Net Cost	£39,668	£38,200	£15,000
Private Use Adjustment	£9,000	£15,000	£20,180
Net Cost After Adjustment	£32,400	£26,481	£21,750

As you can see, using an LLP can result in significant savings. In this example, running your car through an LLP could save you up to £36,387 over three years compared to the other two methods!

There are several options for managing your car’s business expenses, but choosing the right method depends on your vehicle type, your business needs, and how much you use the vehicle for work.

• Personal Ownership with Mileage Claims: Ideal for simple setups, but may not be the best option for high-value cars.
• Company Ownership with Benefit-in-Kind: Expensive, especially for high-emission vehicles, due to the BIK tax.
• LLP or Partnership: The most tax-efficient method, offering significant savings, particularly for those using their cars primarily for business.

By running your vehicle through an LLP or partnership, you can maximize tax relief, reduce your overall costs, and keep more money in your pocket. Consider your options carefully and, if needed, consult with a tax advisor to determine the best strategy for your business.
