A possible general 'loophole' exists where a reasonable profit occurrs in two out five consecutive years of operations. If this is the case the IRS tends to assume the activity was done for profit, hence the loophole since no challenge may be in order. Note however, that the degree of profit is important compared to the degree of loss.
Very small profits for two years vs large losses for the other 3 years may not be enough to keep the IRS from trying to challenge. Since the challenge is done 'after-the-fact,' the IRS has the benefit of hindsight. It's too late for you to go back in time to shore up your position.
If you lose this challenge, these losses, both future and past (within the appropriate statute of limitations), can be disallowed resulting in a possible hefty tax bill for you to pay - plus interest and possible penalties. So contemporaneous recordkeeping and marketing activities are the watchwords here. However, if you do your homework and the loss-producing activity is ... more.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
