On the farm side, for example, Germany allows the transfer of businesses from one generation to the next without invoking capital gains. It's not until you sell your business to, what I would call an arm's-length institution, individual, entity, however it's defined in the tax code, do you trigger that capital gain.
I've run into the situation in my area where families will spend a lot of money on tax planning, which I believe should be spent in another area, trying to allow the business to continue to operate, but then some have to make the ultimate decision to sell.
If anybody else could add some colour on it, that would be great.
