Quick answer · 2026/27 ## Electric company car tax starts with a 4% BIK rate For a fully electric, zero-emission company car in 2026/27, the BIK percentage is 4%. The taxable benefit is broadly the adjusted P11D value multiplied by that percentage; your marginal income-tax rate then determines the tax you pay. Zero-emission BIK rate**4%**2026/27 £50,000 EV**£2,000**annual taxable benefit before other adjustments 20% taxpayer**£33.33/mo**illustrative income tax on that £2,000 benefit **EV-only calculator:** this company car tax calculator is for fully electric, zero-emission cars such as Tesla models. It does not calculate petrol, diesel or plug-in hybrid CO₂/electric-range bands. ## 1. Enter the electric company car value and tax year Use the statutory P11D/list-price value supplied for the company car, not the monthly lease payment or current used-car value.

This keeps the calculator usable for different UK tax positions, including Scottish rates, without pretending one band fits everyone.

Published policy then increases the zero-emission rate by two percentage points a year, to 7% in 2028/29 and 9% in 2029/30. This is why a **BIK calculator** and a lease-payment calculator answer different questions: company car tax is based on the taxable benefit, not simply what the employer pays to lease the car. For a fully electric company car, the calculation starts with the statutory car value used for BIK, usually based on the P11D/list price. A qualifying employee capital contribution can reduce that value by up to £5,000. The adjusted value is multiplied by the zero-emission BIK percentage for the tax year, then any qualifying required payment for private use is deducted from the benefit. Your marginal income-tax rate gives an estimate of the personal tax cost. ## How this company car tax calculator works ## Example: company car tax on a £50,000 electric car **2026/27 at 4%** £50,000 × 4% = **£2,000 taxable benefit**. At a 20% marginal income-tax rate: **£400/year**. At a 40% marginal income-tax rate: **£800/year**. The taxable benefit and the tax bill are not the same number. The BIK percentage calculates the cash-equivalent benefit; your tax position determines how much income tax that benefit creates. ## Why the P11D value matters HMRC's company-car rules use the statutory list price, including relevant accessories, rather than simply the employer's lease rental or the car's current resale value. If the employee made a qualifying capital contribution towards the car or accessories, HMRC allows a deduction capped at £5,000. ## What the calculator does not attempt to model - Periods when a car is unavailable and statutory availability adjustments - Every form of employee payment or payroll adjustment - The full salary-sacrifice cashflow, including pension and National Insurance effects - Employer scheme fees, insurance, maintenance or early-termination terms - Your complete personal tax calculation For a salary-sacrifice Tesla, the BIK estimate is only one piece of the decision. See the [Tesla company car tax and salary sacrifice guide](https://drivequery.com/en/tesla-company-car-tax/) for the surrounding rules. Own car or company car? ## BIK and mileage allowance solve different problems. An employee-owned Tesla can use the 55p/25p AMAP system for qualifying business travel. A company Tesla can create BIK and uses separate Advisory Electric Rates for business electricity.

No. It is designed for fully electric, zero-emission company cars such as a Tesla. Petrol, diesel and plug-in hybrid cars use CO₂ and, for some hybrids, electric-range bands that this simplified calculator does not model. What BIK rate does a Tesla use in 2026/27? A fully electric, zero-emission company car uses 4% in tax year 2026/27. Why does the calculator ask for P11D value? Company-car benefit is based on statutory list-price rules, not simply the monthly lease payment or current used price. Does the calculator work for salary sacrifice? It estimates the company-car BIK element. It does not calculate whether a specific salary-sacrifice agreement is financially worthwhile because that also depends on the salary given up, tax and National Insurance, pension treatment and the scheme terms. Why can I enter my own income-tax rate? The taxable benefit is added to employment income, and UK income-tax bands vary with circumstances and location. A custom marginal rate avoids assuming one band fits every employee. Does low private mileage reduce the BIK percentage? Normally no. Company-car benefit is generally driven by availability for private use rather than the number of private miles driven. ## Official sources - [HMRC – Company car benefit appropriate percentage](https://www.gov.uk/guidance/company-car-benefit-the-appropriate-percentage-480-appendix-2) - [HMRC – Company car tax rates 2028/29 and 2029/30](https://www.gov.uk/government/publications/income-tax-company-car-tax-rates-2028-to-2030/taxation-of-company-cars-the-appropriate-percentage-for-tax-years-2028-to-2029-and-2029-to-2030) - [HMRC – P11D company-car valuation](https://www.gov.uk/guidance/how-to-complete-forms-p11d-and-p11db) - [GOV.UK – Official company car tax calculator](https://www.gov.uk/calculate-tax-on-company-cars) DriveQuery's EV company car tax calculator is a quick educational estimate.
