Hi I'm looking at upgrading to a 2014 WRX STi after years of my old, boring 1.6 Astra, now I've reached the age of not-quite-as-ridiculous insurance premiums. However I'm a bit confused how the tax on selling cars works - the Astra was given to me and I can still sell it for a few grand, however if it does count as income because I paid nothing for it, it would push me into the next up tax band says this salary calculator (https://www.income-tax.co.uk/). Can someone put my mind to rest? Would be much appreciated before I pull the trigger on the new car and start looking to get rid of the Astra.
Cheers!
