There are some Government grants that are available for EXPANSION OF businesses (but not to establish a new business). When a government agency makes funds available for a grant, it places an announcement in the Federal Register which is issued every weekday. For the major part, these grants are very specialized. Moreover, many Government grants are not available through the year. That is, you can't apply for most of them at any time you wish -- in practical, you can apply for them only when they are announced by a Government agency.
The development of corporations has turned out to be a great boon for American as well as world economy. Basically a corporation is understood as a lawful body that entitles a group of people to act as unit or an individual. But since past few decades a new dimension is given to the term corporation. Corporation now refers to both profit and non-profit businesses that are identified or classified according to their tax structure. Corporations are taxed differently, not like normal businesses. On the basis of taxation, corporations are divided into two categories- C- corporations and S-corporations.
