I have some management share options that are exerciseable in a week or so and don't want to pay the excruciatingly painful tax that will be coming my way, circa 42% im guessing.

So i wondered if i could buy the shares at the exercise cost which is £39k get the share certificate give half to my mrs then transfer into an stocks and shares isa with HL so 19K each, then sell the shares through the and be free from CGT and income tax?

Does that sound like a thing that could be done?

Cheers
Dave
