Actually that is the technical definition, but for TAXATION purposes, small businesses can be S-Corps, S Corporations, sole proprietorships or partnerships, including limited liability companies that put LLC instead of Inc. at the end of their names.
All are considered pass-through structures, in which company profits are passed directly to individual owners, who then pay taxes. Traditional corporations pay taxes on profits and pass along dividends to individuals, who pay taxes on the dividends.
It’s not the income that’s small, it’s not the number of employees that’s small, it’s just the total number of owners that’s small. In the case of S corporations, the total number of owners can be 100.
Businesses that fit this description for TAX purposes and therefore get small-business breaks include:
-Enterprise Products Partners, L.P., a pipeline company with 2009 revenues of $25 billion.
-Kohlberg Kravis Roberts & Co., a Wall Street firm with $445 million in revenue in 2009.
