From this Wednesday 1st October, the DVLA will no longer issue tax discs and when you buy a car you wont have any benefit of tax left to run.
If you sell a car say in June with the tax running out at the end of August you can get two months money back, but will lose the cut for June. But the person buying the car will have to tax the car from June, so the Gov gets double the money for that month.
So from Wednesday, are you going to remove the tax disc and it's holder, leave it till it runs out or like me put a nice picture in the holder?
Also funny if you look online or ebay, there are still lots of people selling tax disc holders.
