This guide is fully updated for the 2026/27 HMRC tax year. All calculations and tax rules have been audited against official UK legislation and statutory guidance.
In recent years, the UK government has restructured the company car tax system to penalize fossil-fuel vehicles and reward the adoption of zero-emission transportation. This strategy has made electric vehicles (EVs) the most tax-efficient benefits-in-kind available to UK employees and business directors. This detailed guide analyzes electric company car tax rates (BIK) for the 2026/27 tax year, explains hybrid vehicle tax rules, details corporate capital allowances, and discusses salary sacrifice car schemes.
1. The 2% BIK Rate: Why Electric Company Cars are Incredibly Cheap
For the 2026/27 tax year, the Benefit-in-Kind (BIK) rate for zero-emission electric vehicles is fixed at 2%. This extremely low rate makes driving a premium electric car highly affordable. For example, if you choose a Tesla Model 3 with a P11D value of £42,000, your annual taxable benefit is calculated as follows:
Taxable Value = £42,000 × 2% = £840
Depending on your tax band, the annual tax you pay is:
- Basic Rate (20%): £168 per year (£14 per month)
- Higher Rate (40%): £336 per year (£28 per month)
- Additional Rate (45%): £378 per year (£31.50 per month)
Compare this to a comparable petrol executive saloon costing £42,000 with a BIK band of 30%, which would cost a Higher Rate taxpayer £5,040 in tax per year (£420 per month). The savings from switching to electric are massive.
2. Plug-in Hybrids (PHEVs): The Importance of Electric Range
Plug-in hybrid cars also receive tax incentives, but their BIK bands are determined by their CO2 emissions AND their electric-only driving range. HMRC places hybrid vehicles with CO2 emissions between 1g/km and 50g/km into five distinct bands based on the mileage they can travel on battery power. For example, hybrid cars that can travel 130 miles or more on a single charge qualify for the 2% BIK rate. However, hybrid cars with an electric range of under 30 miles face a 14% BIK rate, which increases the tax bill significantly.

3. Corporate Tax Incentives: 100% First-Year Capital Allowances
If you are a limited company director, buying a brand-new electric vehicle directly through the company offers substantial corporate tax savings. New and unused zero-emission cars qualify for 100% First-Year Allowances (FYA). This means the entire purchase price of the vehicle can be deducted from your company’s taxable profit in the year of acquisition. If your company pays the marginal corporation tax rate of 25%, buying a £40,000 electric vehicle reduces your Corporation Tax liability by £10,000 immediately.
4. Workplace EV Charging: Tax-Free Charging Perks
HMRC provides additional tax exemptions for electric company car drivers. If your employer provides EV charging facilities at the workplace, charging your electric company car (or your private electric car) at work is completely tax-free. Furthermore, if you drive a company electric vehicle and pay for charging at home, your employer can reimburse you tax-free for the cost of electricity used for business travel, calculated using HMRC’s Advisory Electricity Rate (AER), currently set at 7p per mile.
5. Frequently Asked Questions (FAQs)
Q: Does my employer pay tax on my electric company car?
A: Yes. Employers must pay Class 1A National Insurance Contributions (NICs) on benefits-in-kind. However, because the taxable BIK value for electric cars is so low (2%), the employer’s Class 1A NI liability (currently 13.8%) is minimal.
Q: Can I lease an EV through a Salary Sacrifice scheme?
A: Yes. EV salary sacrifice schemes allow employees to pay for lease cars out of their gross salary, saving Income Tax, NI, and pension contributions, while only paying the 2% BIK rate.
Q: Will electric car tax rates increase in the future?
A: Yes. The government has announced that electric vehicle BIK rates will increase by 1% each year starting in April 2025, reaching 5% by the 2027/28 tax year.
