"look at the annual reports they file"

only applicable for public companies or those with enough shareholders that they have to issue public reports. For small startups it doesn't apply.

FYI: Just did the biannual report for NY state (for a small partnership) -- they don't ask for income; they just want a statement of ownership

Depends on the area and country. Some small non public companies that I'd consider start up have had to file reports.
