This guide describes certain basic considerations and costs involved in forming a Delaware or California corporation. Although Delaware and California law are emphasized, the legal concepts are much the same in other states. One important tip is that you should avoid making business decisions in a vacuum. Instead, consider how a decision may impact future alternatives. For example, an improperly priced sale of common stock to founders immediately followed by a sale of preferred stock may result in a significant tax liability to the founders. Another example is that converting a limited liability company into a corporation immediately before the business is acquired, rather than at an earlier time, may prevent the transaction from being tax-free.
