The example: Toyota C-HR 2.0 Plug-in Hybrid, 40% taxpayer
List price £39,175, CO2 19 g/km, electric range in the 40–69 mile band (Toyota’s published BIK rate places it there).
- 2026/27 BIK rate: 1–50 g/km with 40–69 miles of range = 10%.
- Benefit: £39,175 × 10% = £3,918.
- Your tax at 40%: £1,567 a year.
Why 2028/29 is different
From 6 April 2028 the electric-range bands disappear. Every car with 1–50 g/km goes to a flat 18%, then 19% in 2029/30 and 20% in 2030/31.
| Tax year | BIK % | Benefit | Tax at 40% | Tax at 20% |
|---|---|---|---|---|
| 2026/27 | 10% | £3,918 | £1,567 | £784 |
| 2027/28 | 11% | £4,309 | £1,724 | £862 |
| 2028/29 | 18% | £7,052 | £2,821 | £1,410 |
| 2029/30 | 19% | £7,443 | £2,977 | £1,489 |
| 2030/31 | 20% | £7,835 | £3,134 | £1,567 |
2026/27 rates by electric range (1–50 g/km)
| Electric range | 2026/27 | 2027/28 | 2028/29 |
|---|---|---|---|
| 130 miles or more | 4% | 5% | 18% |
| 70–129 | 7% | 8% | 18% |
| 40–69 | 10% | 11% | 18% |
| 30–39 | 14% | 15% | 18% |
| Under 30 | 16% | 17% | 18% |
The Euro 6e-bis easement
Newer plug-in hybrids tested under Euro 6e-bis often show higher official CO2 (51 g/km or more). HMRC lets these cars be treated as 1 g/km, so they keep the lower rates, if first registered from 1 January 2025 and made available by 5 April 2028. Tick the easement box in the calculator if your car qualifies.
Should you still choose a plug-in hybrid?
- If your lease ends before April 2028, the low rates apply for its whole life.
- If it runs into 2028/29 or later, compare with a fully electric car: 7% in 2028/29 against 18%.
- If your employer pays for fuel, the fuel benefit charge uses the same BIK percentage and can add a lot.
Model figures (CO2, engine size, list price) come from the manufacturer’s own UK price list, as on the main calculator. Prices change often — check the current list price for your exact version.
How do I find my car’s electric range?
Look for the WLTP “equivalent all-electric range” (EAER) on the manufacturer’s data sheet, the car’s certificate of conformity or your company’s fleet list. It is measured in miles. Toyota does not publish the exact range in its price list for these two plug-in hybrids, but its quoted BIK rate places both in the 40–69 mile band, so the calculator uses 40 miles. If your figure is different, type it into the “Electric range” box.
In short: on a lease ending by April 2028 a plug-in hybrid can be a good deal; beyond that, check the numbers carefully.
