Understanding Emissions Taxes

In the United Kingdom, the government bases the automobile tax charge on a percentage of the car price graduated according to the level of the car's carbon dioxide (CO₂) emissions. See the CO₂ Emissions Tax Table on the Inland Revenue site for appropriate charges.

Use the emissions data table to add new rates or adjust the values of rates that are already defined in the system.

The system also contains predetermined data for engine types and the associated discounts. Use the Define Engine Type (or Setup Engine Types) table to add new engine types and discounts or adjust the values already defined in the system.

These discounts apply only to cars that were first registered on January 1, 1998 or later.
