If you can get the CEO's interested, yes. If not, you may want to go the 75% tax route.
On the 0% tax route, you'll make more then the 30% tax rate in other sources of revenue from Enterprise and other Publicly controlled corps - primarily in corporate contributions for resources used etc. If you are interested in attracting outside investments, other things to work on are the labor pool and your welfare index.
I'm a retread, but for all intents and purposes I'm new too. A lot has changed.
Best of luck,
