In addition, it has to be at a university that's applied for a "tax-exempt area" (the university has to make the application). This is still interesting, but not a blanket no-tax-for-startups program. It's closer to something like the way some countries set up industrial parks or Special Economic Zones or Free Trade Zones with special tax incentives. Except, any university in the state of NY can apply to turn itself into such a zone, rather than it only being a specific port or industrial park.
