Using electric cars for business in the UK combines unusually strong tax advantages with lower running costs than petrol or diesel equivalents. Whether you run a limited company, manage a fleet, or are an employee with a company car, the combination of a 4% BIK rate in 2026/27, 100% First Year Allowance on outright purchases, and exemption from Clean Air Zone charges makes the EV business case more compelling in 2026 than it has ever been.
This guide consolidates the key tax, leasing, and charging facts you need if you are considering or already using electric cars for business purposes.
Key Takeaways
- Electric company cars attract a 4% BIK rate in 2026/27, rising to 9% by 2029/30 — far below the 25%—37% rates for petrol and diesel equivalents.
- Businesses purchasing electric cars outright can claim 100% First Year Allowance, reducing corporation tax by 19%—25% of the car’s cost in year one (verify availability at GOV.UK — currently extended to 31 March 2027).
- Leased electric cars are an allowable business expense; 50% of VAT on lease payments is recoverable where private use exists.
- HMRC’s Advisory Electric Rate for business mileage reimbursement is 7p per mile (home charging) and 15p per mile (public charging), from 1 March 2026.
- Salary sacrifice EV schemes let employees drive a new electric car on pre-tax salary, saving both employee and employer tax and NI costs.
Company Car Tax on Electric Cars
When an employer provides an employee with an electric car, HMRC taxes the employee on the value of the benefit through a Benefit-in-Kind (BIK) charge. For fully electric (zero-emission) cars, the BIK appropriate percentage is:
| Tax year | BIK rate |
|---|---|
| 2025/26 | 3% |
| 2026/27 | 4% |
| 2027/28 | 5% |
| 2028/29 | 7% |
| 2029/30 | 9% |
Source: GOV.UK. Verify before making financial decisions.
How it works in practice:
The annual BIK tax = P11D value × BIK % × employee’s income tax rate.
A higher-rate taxpayer (40%) in a £42,000 electric car in 2026/27 pays:
£42,000 × 4% × 40% = £672 per year (~£56 per month)
A comparable petrol car at £38,000 and 28% BIK would cost the same taxpayer:
£38,000 × 28% × 40% = £4,256 per year (~£355 per month)
The monthly saving is nearly £300. Even as BIK rates rise through 2029/30, electric company cars remain the most tax-efficient option in the fleet market.
Buying an Electric Car Through a Limited Company
If you run a limited company, buying an electric car through the business offers significant tax advantages.
100% First Year Allowance (FYA)
Businesses purchasing a new zero-emission car can claim 100% of the car’s cost against taxable profit in the year of purchase. For a company paying 25% corporation tax, a £50,000 electric car generates a £12,500 corporation tax saving in year one.
This relief is confirmed to be available for expenditure incurred on or before 31 March 2027 (for companies) and 5 April 2027 (for unincorporated businesses). Verify the current position at GOV.UK before purchasing.
FYA applies to outright purchases and hire purchase agreements but not to operating leases. If you lease the car, the monthly rental payments are an allowable business expense instead (see below).
BIK as a director
If you use the company car for any private journeys, you pay BIK as a director. The BIK is calculated on the P11D value at 4% in 2026/27. The company pays Class 1A NI (15%) on the benefit value, but this is a far smaller sum than the NI that would have been due on the equivalent value taken as salary.
VAT recovery
If the car is available for any private use (which covers virtually all directors’ company cars), you can reclaim 50% of the VAT on purchase or lease payments. If the car is used exclusively for business — with no private use at all, which is difficult to evidence for a single director — 100% VAT recovery is permitted, but HMRC scrutinises this claim closely.
Leasing vs Buying an Electric Car for Business
The choice between leasing and buying an electric car for business affects both tax treatment and cash flow.
| Factor | Buying outright | Business Contract Hire (leasing) |
|---|---|---|
| Capital outlay | Full purchase price upfront (or HP) | Initial rental only |
| Tax relief | 100% FYA in year one (zero-emission, verify at GOV.UK) | Monthly rentals as business expense |
| VAT recovery | 50% on purchase (if private use) | 50% on lease payments (if private use) |
| Residual value risk | Company carries risk | Leasing company carries risk |
| Flexibility | Own the asset; sell when needed | Fixed term; hand back at end |
| Balance sheet | Asset appears on balance sheet | Off-balance-sheet (operating lease) |
For many businesses, leasing is preferred because it removes residual value risk, spreads cost over the contract period, and keeps the balance sheet cleaner. However, outright purchase with FYA delivers a larger upfront tax saving.
Leasing Electric Cars for Business: How It Works
Business Contract Hire (BCH) is the standard leasing product for companies. You pay an initial rental (typically three, six, or nine monthly payments upfront) followed by a fixed monthly payment for an agreed term (usually 24—48 months) and agreed mileage limit.
At the end of the contract you return the car and take on a new model. You have no exposure to residual value changes — the leasing company carries that risk.
VAT on business leasing:
If the car is available for any private use:
- 50% of the VAT on monthly lease payments can be reclaimed
- 100% of the VAT on any maintenance package is recoverable
The monthly rental is an allowable business expense against corporation tax or income tax, reducing your taxable profit.
HMRC Mileage Rates for Business Travel in Electric Cars
When employees (or sole traders) use a company electric car for business journeys, HMRC’s Advisory Electric Rates (AER) apply for reimbursements:
| Charging location | AER from 1 March 2026 |
|---|---|
| Home charging | 7p per mile |
| Public charging (under 50kW) | 15p per mile |
Source: GOV.UK. Verify current rates before processing reimbursements.
Reimbursements at or below the AER are tax-free. Electricity is not classified as “fuel” for company car fuel benefit purposes, so there is no fuel benefit charge when an employer reimburses business electricity costs within the AER.
For employees using their own car for business travel and charging at home, the standard HMRC Approved Mileage Allowance Payment (AMAP) rate applies: 45p per mile for the first 10,000 miles and 25p per mile thereafter (2026/27). This covers all running costs including electricity.
Workplace Charging for Business
Installing charge points at your business premises is straightforward and tax-efficient:
- 100% First Year Allowance on charge point equipment (verify current availability at GOV.UK — extended to 31 March 2027)
- Workplace Charging Scheme grant: up to £500 per socket from 1 April 2026 (scheme closes 31 March 2027 — verify at GOV.UK)
- No BIK for employees: providing workplace charging available to all staff creates no taxable benefit
A 7kW AC charge point covers overnight or full-day charging needs for most cars and vans. For larger fleets, 22kW units or DC rapid chargers may be needed depending on throughput requirements.
Salary Sacrifice: Extending the Tax Advantage to All Employees
A salary sacrifice EV scheme lets your employees drive a new electric car funded from pre-tax salary. The combined tax and NI savings make it the most cost-efficient way for most employees to access a new electric car, and the employer saves employer NI on the sacrificed salary amount.
Key facts:
- BIK at 4% (2026/27) applies to salary sacrifice cars, but income tax and NI savings on the sacrificed salary typically more than offset this
- The employer leases the car and sublets to the employee; Complete Employer Protection covers early termination risk
- The scheme can run alongside or instead of a traditional fleet policy

Frequently Asked Questions
Can I buy an electric car through my limited company? Yes. Buying an electric car through your limited company lets you claim 100% First Year Allowance against corporation tax (verify the current availability window at GOV.UK). You will pay BIK tax on the car as a director, but at 4% for 2026/27 the cost is far lower than the equivalent benefit through salary. The company can also reclaim 50% of the VAT on the purchase.
Is leasing or buying better for tax on a business electric car? Buying with 100% FYA gives a larger upfront tax saving in year one. Leasing spreads the cost over the contract period, removes residual value risk, and keeps the balance sheet cleaner, with monthly rentals as an allowable expense. The right choice depends on your cash flow and balance sheet priorities.
What is the Advisory Electric Rate for 2026? From 1 March 2026, the HMRC Advisory Electric Rate is 7 pence per mile for home charging and 15 pence per mile for public charging (under 50kW). Reimbursing employees at these rates for business mileage in a company electric car is tax-free. Verify current rates at GOV.UK before processing claims.
