I think the current government was looking into that at some point, but I don't know what happened with that. I remember when I worked at a startup the choice when I got stock options was - pay the tax up front based on the current strike price value - or pay a higher tax when you exercise them and make a profit. If you take the first choice then you'll need to do a lot of paper work to get that money back should the company fail.
