I made a $1.8M investment into a company in 2007 and have not shown a profit for the business on my tax returns since. For the past 4 years I have written off close to $600,000 in business expenses as an LLC, this has reduced my total adjusted gross income from previous jobs that I have held. Is there a limit to the number of losses that I can continue to write off each year without showing income from the LLC?

The company I invested in is private and submits independent tax returns, I act as the Chairman but do not receive any reportable income.

This seems to be acceptable with the IRS?
