Road tax for a 2015 Subaru Forester

The Vehicle Certification Agency lists 20 petrol and diesel versions of the Subaru Forester in its data from August 2013 to August 2015, from 148 to 197 g/km CO2 [3]. A car first registered from 1 March 2001 to 31 March 2017 is taxed by CO2 band, so that is bands F, G and J: from £225 to £410 a year at the 2026/27 rates [2].

J£41019720

Versions listed, not cars sold: this does not say how common each band is. The CO2 figure on the car's V5C log book decides its band. Car tax calculator for a 2015 car

Car tax and ULEZ for a 2015 car

A car first registered in the UK in 2015 was issued a 64 (January–February), 15 (March–August) or 65 (September–December) plate, unless it was registered in Northern Ireland (no age identifier) or has since moved to a private plate. An imported one is plated when first registered here, so its plate can be newer than its first-use year. 15 plates

A 2015 car is taxed by its CO2 emissions band (A to M), shown on the V5C logbook. [2]

For the London ULEZ, a 2015 petrol usually meets Euro 4, and a 2015 diesel may or may not meet Euro 6 (every new diesel car registered from September 2015 does). The Euro standard of the car decides, not the year alone. Hybrids follow the rule for their petrol or diesel engine. [4] ULEZ checker
