What you’ll pay to tax your car this year — the first-year bill on a new one, the £200 everyone pays after that, and the £440 surcharge on pricier cars. Car tax arrives as two very different bills. The first year is a one-off charge set by the car’s CO2, running from a few hundred pounds to over £5,000 — which is why it usually disappears into the on-the-road price and is forgotten. Every year after that is a flat £200, and electric cars have paid it since 1 April 2025, the single fact a general-purpose AI is most likely to get wrong. Then there is the surcharge: any car listed above £40,000 pays an extra £440 a year from its second year to its sixth. For EVs that threshold rose to £50,000 on 1 April 2026 and was backdated to anything registered from April 2025, so even an answer that was correct last year has gone stale. Cars from 2001 to 2017 run on an older CO2 table, which is here as well.
