How we calculate your road tax

What the confidence labels mean

We would rather label uncertainty than hide it. A figure is only as strong as the source behind it, so the label states the source's strength, not our enthusiasm.

• Verified — checked directly against the official government source named in the table below, on the date shown.
• Modelled — built from published legislation or official parameters. Accurate to the structure, but may simplify regional or vehicle-specific variation.
• Indicative — a typical value for orientation, used where rates vary widely by region or where the policy is actively changing. Treat it as a starting point, not an answer.

Why we sometimes show a range

If a discount is being phased out, two owners of the same car can legitimately owe different amounts in the same year. Printing a single figure in that situation would be inventing precision. We show the bounds instead and explain what they represent.

We never invent a missing number

If a model needs an input it does not have — motor power for a power-banded country, weight for a weight-banded country — the calculator asks for it and refuses to answer until it is provided. It will not quietly substitute a default and present it as your tax.

Review cycle

Rates are re-checked against primary sources at the point most countries revise them, and whenever a government announces a change. The "reviewed" date in the footer reflects the last full pass.

Corrections and how to contest a figure

If you believe a figure is wrong, email hello@evroadtax.com with the country, the vehicle details and the source you are relying on. We check corrections against the primary source, then update the calculation, the confidence label and the source note. Corrections that come with a citation to a government publication are handled first.
