Electric Vehicle Tax Reliefs for UK Businesses
Capital Allowances, VAT and Benefit-in-Kind Explained
A practical guide for limited companies and sole traders | Updated 18 August 2026
This article summarises the main UK tax considerations when a business acquires, leases or uses a fully electric car. The tax treatment can vary significantly depending on who owns the vehicle, how it is funded, whether there is private use and whether the business is VAT registered.
1. Limited companies and electric cars
Director using a personally owned car. Where a director uses their own car for qualifying business journeys, the company can reimburse business mileage using HMRC approved mileage rates. For 2026/27, the rate for cars and vans is 55p per mile for the first 10,000 business miles and 25p per mile thereafter. Before 6 April 2026, the first 10,000-mile rate was 45p.
Company-owned car. Where the company owns or provides the electric car, it will normally bear the business running costs and claim the appropriate tax deductions. If the car is available for private use by a director or employee, a taxable company-car benefit generally arises. Fully electric cars benefit from substantially lower benefit-in-kind (BIK) percentages than most petrol or diesel cars.
2. How the funding method affects the tax relief
The precise tax treatment depends on the legal and tax nature of the agreement, not simply the label used by the dealership or finance provider. The main routes are set out below.
2.1 Cash purchase
Capital allowances – new electric car. A new and unused zero-emission car can qualify for a 100% First Year Allowance (FYA), allowing the qualifying cost to be deducted in full for tax purposes. The current extension applies to qualifying expenditure incurred up to 31 March 2027 for Corporation Tax and 5 April 2027 for Income Tax.
Used electric car. The 100% FYA is not available for a second-hand electric car. A used zero-emission car normally qualifies for main-rate writing-down allowances. The main rate reduced from 18% to 14% from 1 April 2026 for Corporation Tax and from 6 April 2026 for Income Tax. If an accounting period straddles the change date, a hybrid rate may apply.
Managing a tax loss. A business does not have to claim the full FYA. It may restrict the claim where appropriate, for example to manage the timing of tax losses and reliefs.
Electric vehicle chargepoints. Qualifying new and unused electric vehicle charging equipment can also qualify for a 100% FYA within the applicable time limits. A charging point installed at a director or employee’s home in connection with a company car can also have favourable employment-tax treatment, discussed below.
VAT on purchase. VAT on the purchase of a car is generally blocked where the car is available for private use. Full VAT recovery can be possible only in limited circumstances, for example where the car is genuinely used exclusively for business and is not made available for private use, subject to the detailed VAT conditions.
2.2 Hire purchase / qualifying lease purchase
Capital allowances. Hire purchase is treated differently from an ordinary finance lease for capital-allowance purposes. Under a qualifying hire purchase arrangement, the hirer can generally claim plant and machinery allowances once the vehicle is brought into use, subject to the normal rules for new or used cars.
Accounting treatment. The vehicle and the related finance liability are normally recognised on the balance sheet under the applicable accounting standard. Capital repayments reduce the finance liability rather than being charged as an operating expense; the finance/interest element is recognised separately. Capital allowances, rather than accounting depreciation, determine the tax deduction for the vehicle itself.
VAT. Where the agreement is effectively a purchase for VAT purposes, the normal VAT block on car purchases may apply if the car is available for private use. The exact agreement should be reviewed before claiming VAT or capital allowances.
2.3 Finance lease
Capital allowances. A finance lease is not the same as hire purchase for tax purposes. HMRC’s general rule is that the finance lessor, rather than the finance lessee, is entitled to the capital allowances. Different rules can apply to long funding leases and certain lease purchase arrangements, so the contract terms should be reviewed carefully.
Tax relief and VAT. The lessee’s tax deduction will normally follow the specific leasing and accounting rules rather than a capital-allowance claim by the lessee. For VAT, the finance element of a qualifying car lease is potentially subject to the 50% input-tax block where there is private use; the remaining VAT is still subject to the normal business-use and partial-exemption rules.
2.4 Contract hire / operating lease
Capital allowances. Under a normal contract hire or operating lease, the leasing company retains ownership and the business using the car does not normally claim capital allowances on the vehicle. Tax relief is instead obtained through the allowable lease costs, subject to the relevant tax and accounting rules.
VAT. Where a qualifying leased car is used for both business and private purposes, most businesses are normally blocked from recovering 50% of the VAT on the finance/lease charge. The remaining 50% is subject to the normal VAT rules, including business-use and partial-exemption restrictions. VAT on separately identified maintenance charges may be treated differently.
Summary of common funding routes
Funding method | Capital allowances for user? | Main tax relief | VAT position (typical private use) |
Cash purchase | Yes | New/unused zero-emission car: 100% FYA; used EV: normally 14% main-rate WDA from April 2026 | Purchase VAT generally blocked if private use is available |
Hire purchase / qualifying lease purchase | Generally yes for the hirer | Capital allowances under HP rules; finance interest dealt with separately | Often follows purchase VAT treatment; review agreement |
Finance lease | Generally no (unless specific long-funding/lease rules apply) | Relief under leasing/accounting tax rules | Normally 50% VAT block on finance charge where private use exists |
Contract hire / operating lease | No | Allowable lease costs subject to tax/accounting rules | Normally 50% VAT block on finance charge where private use exists |

3. Benefit-in-kind tax implications
A company-car benefit generally arises where a company car is made available to a director or employee and private use is permitted. The taxable benefit is broadly based on the car’s list price and the applicable BIK percentage, with adjustments in certain circumstances.
For fully electric cars (0g/km), the BIK percentages are:
| Tax year | Fully electric BIK rate |
| 2024/25 | 2% |
| 2025/26 | 3% |
| 2026/27 | 4% |
| 2027/28 | 5% |
| 2028/29 | 7% |
| 2029/30 | 9% |
Example – £50,000 electric company car in 2026/27
- List price: £50,000
- BIK rate: 4%
- Taxable car benefit: £2,000
- Director/employee Income Tax: £400 at 20%, £800 at 40%, or £900 at 45% (where those rates apply)
- Employer Class 1A NIC at 15%: £300
Reporting for 2026/27. Where the benefit is not payrolled, the employer normally reports it on form P11D and reports the Class 1A NIC on form P11D(b). Where a benefit is validly payrolled, an employee P11D is generally not required for that payrolled benefit, although the employer still has end-of-year Class 1A reporting obligations. Class 1A NIC on work benefits is generally due by 22 July following the end of the tax year when paid electronically.
Change from 6 April 2027. Mandatory real-time payrolling is being introduced for company cars, car fuel, vans, van fuel and employer-provided medical benefits from April 2027. Businesses should ensure their payroll software and processes are ready for the new reporting regime.
Home charging point. Where an employer pays for a vehicle charging point to be installed at an employee or director’s home in connection with a taxable company car, HMRC guidance provides that no separate taxable benefit arises for the charging point.
Advisory Electric Rates (AER). From 1 June 2026, HMRC’s advisory rates for fully electric company cars are 7p per mile for home charging and 15p per mile for public charging. These rates are reviewed periodically, so the current HMRC rate should always be checked when making reimbursements.
Suppose a director receives a salary of £12,570 and then receives £30,000 in dividends during 2026/27.
Their total income is £42,570.
The dividend is not automatically taxed at one single rate. The calculation depends on how their total taxable income interacts with the relevant tax bands and allowances.
The first £500 of dividend income falls within the dividend allowance. The remaining dividend income may then be taxed at the applicable dividend rate depending on the individual’s overall income position.
This is why simply saying “dividends are taxed at 10.75%” is incomplete.
The rate depends on the shareholder’s circumstances.
A director with employment income, rental income, pension income or other taxable income may have a very different outcome from another director receiving the same dividend.
4. Sole traders
A sole trader generally has two broad methods for claiming car costs: actual-cost/capital-allowance treatment or HMRC simplified mileage. The method chosen affects what can be claimed in later years.
Actual-cost / capital-allowance basis. A new and unused zero-emission car can qualify for the 100% FYA within the applicable time limit. A used zero-emission car normally qualifies for main-rate WDA, which is 14% from 6 April 2026 for Income Tax. If the car is also used privately, capital allowances and relevant running costs must be restricted to the business-use proportion. BIK does not apply to the sole trader’s own private use; instead, the private-use restriction reduces the deductible business amount.
Example. If a sole trader buys a qualifying new electric car for £40,000 and business use is 50%, the maximum FYA attributable to the business use would generally be £20,000, subject to the normal capital-allowance conditions.
Leased car and VAT. If the sole trader is VAT registered and leases a qualifying car that is also used privately, the 50% VAT block can apply to the finance element of the lease charge. The remaining VAT is then subject to the normal business-use rules. For example, if a lease charge is £400 + £80 VAT and business use is 50%, the 50% lease block leaves £40 potentially recoverable, and applying 50% business use would reduce the input VAT claim to £20, subject to the detailed VAT rules.
Simplified mileage. For 2026/27, a sole trader using simplified vehicle expenses can claim 55p per mile for the first 10,000 business miles and 25p per mile thereafter for a car or van. Once the flat-rate basis is adopted for a particular vehicle, it must normally continue to be used for as long as that vehicle remains in the business. Actual vehicle running costs and capital allowances cannot also be claimed for that same vehicle.
Records. Accurate records of business mileage, private mileage, invoices, lease agreements, charging costs and other supporting documents should be retained to support the tax and VAT treatment.
BIK charges, VAT blocks, mileage claims and capital allowances all interact, and the right answer is different for every business. Aksons Accounting runs the numbers on your circumstances so you can compare a company car against personal ownership with confidence. From capital allowance claims to P11D filing and payrolling readiness for April 2027, we make sure your electric vehicle tax relief for UK businesses is claimed correctly and defensibly.

5. Practical points before choosing an electric vehicle
- Check whether the vehicle will be purchased, acquired on hire purchase, financed under a true finance lease, or taken on contract hire – the labels used commercially do not always determine the tax treatment.
- Confirm whether the car is new and unused or second-hand, as this can materially change the available capital allowances.
- Consider expected private use before assuming VAT can be recovered on a purchase.
- Compare the low company-car BIK charge with the alternative of personal ownership and mileage reimbursement.
- Review the agreement and tax treatment before signing finance documentation, particularly where there is a balloon payment or purchase option.
- Recheck HMRC rates at the time of the transaction, as mileage, advisory electric rates and future company-car percentages can change.
