Tax Relief on Electric Cars UK for Self-Employed: 2026 Guide
Kausik MukherjeeBusiness Tax, Start-up New Business
Electric vehicles (EVs) can offer significant tax and running-cost advantages for UK business owners. Depending on how a vehicle is purchased, owned and used, potential benefits include capital allowances, lower company-car Benefit-in-Kind (BIK) rates, business mileage deductions and grants for eligible charging infrastructure.
However, the rules are different for sole traders, partnerships and limited companies. Understanding these differences is essential before choosing an electric vehicle for business use.
In this guide, we explain the key electric car tax benefits available in the 2026–27 tax year, the latest rates, eligibility conditions and practical considerations for self-employed professionals and company directors.
Tax Relief on Electric Cars UK for Self-Employed: What’s Available in 2026
1. Capital Allowances
Capital allowances allow eligible businesses to deduct qualifying expenditure on business assets from taxable profits. Electric cars may qualify for particularly favourable treatment, depending on the vehicle and purchase date.
100% First-Year Allowance
Qualifying new and unused zero-emission cars can qualify for a 100% First-Year Allowance (FYA). This allows the full qualifying cost to be deducted from taxable profits in the relevant accounting or tax period.
The allowance is currently scheduled to be available for qualifying expenditure incurred:
- Before 31 March 2027 for Corporation Tax purposes.
- Before 6 April 2027 for Income Tax purposes.
Eligibility conditions apply. In particular, a second-hand electric car does not qualify for this particular 100% allowance.
Example: A qualifying business purchases a new electric car for £35,000 and is entitled to claim the full amount as a capital allowance. The business may deduct £35,000 from its taxable profits, subject to the relevant rules.
This is a deduction from taxable profits, not a £35,000 tax refund. The actual tax saving depends on the business’s circumstances.
Sole traders using a car for both business and private journeys generally need to restrict the allowance to the appropriate business-use proportion.
Writing-down allowances
Where a car does not qualify for the 100% First-Year Allowance, capital allowances may be available through the writing-down allowance system.
The main rates to be aware of are:
| Allowance | Rate |
|---|---|
| Main-rate writing-down allowance for relevant expenditure from April 2026 | 14% |
| Previous main-rate allowance | 18% |
| Special-rate writing-down allowance | 6% |
| Qualifying new and unused zero-emission car | Potentially 100% FYA |
The 14% main rate applies to relevant expenditure under the rules effective from 6 April 2026 for Income Tax businesses and 1 April 2026 for Corporation Tax businesses. Earlier expenditure may remain subject to the previous rate.
Second-hand electric cars generally qualify for main-rate capital allowances rather than the 100% FYA. The precise deduction depends on the applicable rules and the capital allowances pool.
2. Electric company cars and Benefit-in-Kind tax
Limited companies may provide electric cars to directors or employees. Where a company car is available for private use, including commuting, a taxable Benefit-in-Kind (BIK) can arise.
Fully electric company cars have historically benefited from low BIK percentages compared with many petrol and diesel vehicles.
Electric company-car Rates for Benefit-in-Kind (BIK)
The published rates for fully electric company cars are:
| Tax year | BIK percentage |
|---|---|
| 2025–26 | 3% |
| 2026–27 | 4% |
| 2027–28 | 5% |
| 2028–29 | 7% |
| 2029–30 | 9% |
These are percentages used to calculate the taxable benefit, not the percentage of the vehicle price paid directly in tax.
Example of a company-car benefit
Suppose a company provides a fully electric car with a taxable list price of £40,000 in 2026–27.
Using a 4% BIK percentage:
£40,000 × 4% = £1,600 taxable annual benefit.
If the director’s applicable marginal Income Tax rate were 20%, the illustrative personal tax on that benefit would be £320 for the year.
The actual calculation may depend on the vehicle’s appropriate list price, accessories, availability period and other applicable rules.
The company may also have a Class 1A National Insurance liability on the taxable benefit.
Important: Company-car BIK rules do not automatically apply to a car personally owned by a sole trader.
3. Business mileage allowances
Business mileage relief can help cover the cost of using a vehicle for business travel. The rules depend on whether the driver is an employee using their own car or a self-employed person claiming business expenses.
Employee mileage allowance rates for 2026–27
For employees using their own cars for business journeys, the approved mileage allowance rates for tax purposes are:
| Business mileage | Approved rate |
|---|---|
| First 10,000 business miles | 55p per mile |
| Additional business miles | 25p per mile |
For National Insurance purposes, the qualifying rate for cars and vans is 55p per business mile.
These rates apply from 6 April 2026. They should not be confused with the simplified mileage rates available to sole traders.
Simplified mileage expenses for sole traders
Eligible sole traders and certain partnerships may use HMRC’s simplified vehicle expenses method.
For cars and goods vehicles, the standard rates are:
| Business mileage | Simplified expenses rate |
|---|---|
| First 10,000 business miles | 45p per mile |
| Additional business miles | 25p per mile |
This is a separate method from the employee mileage allowance. Eligibility rules apply, and simplified mileage expenses cannot be claimed for a vehicle for which capital allowances have already been claimed.
Example for a sole trader
A sole trader drives 8,000 qualifying business miles and uses the simplified mileage method.
8,000 × 45p = £3,600 allowable business mileage expenses.
This reduces taxable business profits; it is not a direct reimbursement or automatic tax refund.
Keep accurate records of business journeys and distinguish them from private travel and ordinary commuting.
4. Vehicle Excise Duty for electric cars
Electric cars are no longer universally exempt from Vehicle Excise Duty (VED). The amount payable depends on the vehicle’s registration date and applicable tax rules.
VED rates from 1 April 2026 to 31 March 2027
| Electric car registration date | Standard treatment |
|---|---|
| On or after 1 April 2025 | £10 in the first year, then £200 annually |
| 1 April 2017 to 31 March 2025 | £200 annually |
| 1 March 2001 to 31 March 2017 | £20 annually |
These are the standard rates for the relevant vehicle categories. Always check the official guidance for the particular vehicle.
Expensive-car supplement
A qualifying zero-emission car registered on or after 1 April 2025 with a list price of more than £50,000 may also be subject to the expensive-car supplement.
This additional charge applies for five years, beginning with the second year of vehicle tax.
The £200 standard VED rate and the expensive-car supplement are separate charges.
5. VAT on electric cars and charging
VAT recovery can be an important consideration when purchasing and running an electric vehicle through a business. However, the rules are not the same for all vehicle purchases and charging arrangements.
VAT on purchasing an electric car
VAT on the purchase of a car is generally blocked where the car is available for private use. Recovery may be possible where the vehicle is used exclusively for business and the relevant conditions are met.
The position can differ for leased vehicles, cars used by employees and vehicles with mixed business and private use.
Before including VAT recovery in a business case, confirm that the vehicle and its intended use satisfy HMRC’s requirements.
VAT on charging costs
The treatment of VAT on electricity used to charge an electric car depends on the circumstances, including where the charging takes place, who pays for it and the evidence available.
For home charging, business owners should maintain suitable records to support any business-use claim. VAT recovery is not automatically available on the full household electricity bill.
Public charging and workplace charging also need to be considered under the normal input-tax rules.
6. Grants for electric vehicle charging points
Businesses considering installing charging infrastructure may qualify for support through the Workplace Charging Scheme.
From 1 April 2026, eligible workplaces can apply for a grant of up to £500 per socket for qualifying installations. The scheme allows applications for up to 40 sockets across eligible sites.
The scheme is subject to eligibility, application and installation requirements. Its current published funding period runs until 31 March 2027, and the government may change or end grant schemes.
A grant should not be treated as guaranteed funding until eligibility and the application have been confirmed.
7. Electric Car Grant for qualifying vehicles
The government also operates the Electric Car Grant to support the purchase of eligible new electric cars.
The grant is not available on every electric vehicle, and the amount should not be presented as a guaranteed discount for every buyer. Eligibility depends on the vehicle and the current scheme conditions.
The government’s current scheme lists:
- Band 1: up to £3,750.
- Band 2: up to £1,500.
- Eligible new electric cars must be priced at £37,000 or below and meet the scheme’s requirements.
Before including a grant in a purchase calculation, check the latest official eligibility criteria and confirm whether the particular model qualifies.
8. London Congestion Charge and ULEZ
Electric vehicle owners should distinguish the London Congestion Charge from the Ultra Low Emission Zone (ULEZ).
Congestion Charge
Electric cars are no longer universally exempt from the Congestion Charge.
From 2 January 2026, eligible electric cars registered for Auto Pay can receive a 25% Cleaner Vehicle Discount. The standard daily Congestion Charge increased to £18 when paid on the day or in advance, with a higher charge for payment within three days after travel.
The standard charge is £18 when paid in advance, on the day, or by Auto Pay. Eligible electric cars on Auto Pay therefore pay £13.50 per charging day. Payment by the third day after travel costs £21 at the standard rate.
The applicable discount and charge depend on eligibility and payment arrangements.
Ultra Low Emission Zone
Fully electric cars meet the ULEZ emissions standard and therefore do not incur the ULEZ charge. This does not mean they are exempt from every other London road charge.
9. Electric Vehicle Excise Duty from April 2028
The government has announced the introduction of Electric Vehicle Excise Duty (eVED), scheduled to begin on 1 April 2028.
Under the published policy, the proposed mileage-based rates are:
| Vehicle type | Announced rate |
|---|---|
| Battery-electric cars | 3p per mile |
| Hydrogen fuel-cell cars | 3p per mile |
| Plug-in hybrid cars | 1.5p per mile |
The policy is intended to introduce a mileage-based charge alongside the existing vehicle-tax framework.
These are future policy rates, not a charge that applies in 2026–27. The government has published draft legislation and implementation details, so motorists should check for subsequent changes before relying on the figures.
10. Are electric cars cheaper to run for business?
An electric car may reduce some business motoring costs, but the amount saved varies considerably.
Relevant factors include:
- Electricity tariffs and the proportion of charging completed at home.
- Public charging prices and charging frequency.
- Vehicle efficiency and annual mileage.
- Insurance, servicing, tyres and repairs.
- The purchase price, financing costs and depreciation.
- Any applicable taxes, grants and charging-infrastructure costs.
Avoid relying on a single percentage-saving claim without a transparent calculation.
For example, compare the expected annual cost of an electric car and a comparable petrol vehicle using realistic mileage, energy prices, maintenance costs and vehicle ownership costs. This gives a more useful business-specific estimate than a generic claim that every electric car will be a fixed percentage cheaper.
11. Sole trader or limited company: which approach is right?
The tax treatment of an electric car depends on who owns it and how it is used.
Sole traders
A sole trader may consider capital allowances or simplified mileage expenses, depending on the vehicle and the applicable eligibility rules. Business and private use must be treated appropriately.
A personally owned car does not create a company-car BIK charge simply because the owner is self-employed.
Limited companies
A limited company may be able to claim capital allowances on a qualifying vehicle it purchases. If the company provides a car to a director or employee and it is available for private use, BIK and Class 1A National Insurance may also be relevant.
The company’s tax position, the director’s personal tax position and any VAT implications should be considered together.
Neither ownership structure is automatically best for every business. The right choice depends on profits, business mileage, personal use, financing, VAT status and the vehicle’s cost.
12. Practical checklist before buying an electric car
Before purchasing an EV for business use, consider the following:
- Confirm the ownership structure. Decide whether the car will be personally owned or purchased by a limited company.
- Check capital allowance eligibility. Confirm whether the car is new or used, its emissions and the relevant purchase date.
- Calculate any company-car BIK. If a company provides the vehicle, check the rate for the relevant tax year.
- Choose the appropriate mileage method. Do not mix employee mileage allowances with sole-trader simplified expenses.
- Check VED. Confirm the registration-date rules and any expensive-car supplement.
- Review VAT treatment. Confirm the vehicle’s business and private use and the rules for charging costs.
- Investigate eligible grants. Verify the current scheme terms before committing to installation expenditure.
- Compare the total cost of ownership. Include financing, energy, maintenance, insurance, taxes and depreciation.
- Maintain records. Keep invoices, mileage logs and supporting evidence for business expenses and tax claims.
- Seek professional advice where needed. A UK accountant can assess the best treatment for the specific business.
Conclusion
Electric cars can provide valuable tax and operational benefits for UK business owners, but the correct treatment depends on the vehicle, the purchase date, business use and ownership structure.
For 2026–27, the key figures include a 14% main-rate writing-down allowance for relevant expenditure, a 4% BIK percentage for fully electric company cars, employee mileage rates of 55p for the first 10,000 business miles and 25p thereafter, and a standard £200 annual VED rate for the applicable electric-car categories.
Qualifying new and unused zero-emission cars may also benefit from a 100% First-Year Allowance within the applicable time limit. Eligible businesses may access charging grants, while future measures such as eVED are scheduled for later years.
The most effective approach is to evaluate the whole cost of owning and operating an electric vehicle, apply the correct tax rules and verify current HMRC guidance before claiming relief.
