UK road-tax calculator for every regime.

It depends entirely on the date of first registration. Pre-2001 cars are taxed by engine size with a 1549cc threshold. Cars registered between March 2001 and March 2017 are taxed by CO₂ band (A through M). Cars registered from April 2017 onwards pay a CO₂-based first-year charge then a flat £195/year standard rate, with a £425 supplement for years 2–6 if the original list price was over £40,000.

Yes. From 1 April 2025, EVs registered new pay £10 in their first year and £195/year thereafter. EVs registered between April 2017 and March 2025 — previously £0 — also moved to the £195 standard rate from April 2025. The £425 luxury supplement applies to EVs first registered from April 2025 if the list price was over £40,000.

Use the combined WLTP figure for cars first registered after September 2018 — that's what DVLA holds. For older cars, use the combined NEDC figure. The DVLA tax check on gov.uk shows the exact figure stored against the registration.

Yes — imported cars use the same UK rules from the date they're first UK-registered, not their original overseas registration date. That can be a windfall on older imports that escape the 2001–2017 CO₂ regime altogether.

The calculator is indicative — the DVLA holds the definitive CO₂, fuel and engine details against the registration. List-price information for the £40k supplement is also held at DVLA. For the exact figure, run a Full HPI check or use the DVLA's free tax-check tool.
