I am the founder of an LLC and am planning to sell some stock (units). We have a good number of investors/partners who are non active and a sizable tax loss carryforward. What are the basics I need to know in terms of how my gain on the sale of my units get treated from a tax standpoint? Can I take the loss only against the sale of the units or against my ordinary income from the entity? Is there a limit on how much tax I can avoid?
