Quote from MRBRETTONWOODS:
But how often would you need to get it out when most of your net worth will be tied up in assets anyway?
If that's the case, why don't you fast-track into qualified retirement accounts and wait until you're 60/62/65 to pull it out?
Why are you solely looking at a C-corp vs LLC argument. Why not both like the professionals do:
C-corp as the management firm that derives it's income from the LLC, the investment vehicle.
For the LLC to qualify as a partnership, get 2 or more "persons" as investors - you, the management corp, and anybody else you desire, preferably family, friends, or business acquaintances all living in the same state.
Structure properly, and you'd don't have any corporate tax (i.e income = expenses = $0 taxes), just employment taxes. The partnership income is passed through to your personal return.
And if you trade futures, then you get the benefits of the 60/40 blended tax rate, instead of messing with the muddle of "trader status", short term cap gain taxed as personal income, long-term gain, wash sales, $3,000 limit per year on losses, self-employment taxes if you actively manage the LLC, and all the other annoying tax issues...
