What will rising Benefit-in-Kind actually cost you?
Electric company car tax is set to rise from 4% to 9% by 2029/30. The rates are already published, so there are no surprises — and even at 9%, an electric car is taxed at a fraction of the petrol equivalent. See what it means for you.

How this is worked out. BiK tax = list price (P11D) × the BiK percentage for that tax year × your income tax rate. Zero-emission BiK rates are those confirmed by HM Treasury: 4% in 2026/27, 5% in 2027/28, 7% in 2028/29 and 9% in 2029/30. Petrol and diesel rates rise by 1 percentage point in 2027/28, 2 points in 2028/29 and 1 point in 2029/30, capped at 37%, 38% and 39% respectively. All cars emitting 1–50 g/km, including plug-in hybrids, move to 18% in 2028/29 and 19% in 2029/30 regardless of electric range. Figures assume the same list price for both cars and exclude the 4 percentage point surcharge on diesels that do not meet the RDE2 standard. This is an illustration, not tax advice — your own figures depend on your salary, tax code and the exact vehicle.

Electric vehicles have significantly lower BiK rates than petrol or diesel cars. For 2026/27, EVs are taxed at just 4% of their list price, compared to up to 37% for high-emission vehicles. This low rate is locked in until 2028, making EVs particularly attractive for salary sacrifice.

-
No – the car is owned by the leasing company and provided to you by your employer as part of your benefits package. You use it for the duration of the lease term but don't own it. At the end of the lease, you typically return it or have options to extend or purchase depending on the agreement.
