If you choose to create your business entity as a corporation, you can choose between being taxed as a “C corporation” or an “S corporation.” The main difference between the two is that C corporations are subject to double taxation while S corporations are not.
If you choose to be taxed as a C corporation, your income will be taxed once as net income of your business and the second time as the income received by the shareholders from the corporation as dividends.
With an S corporation, the income is only taxed once at shareholder level on the money received from the corporation. Usually small business owners choose the S corporation while larger business choose the C Corporation because of its greater tax planning flexibility.
But, if you are looking to form a smaller corporation, these benefits does not help you very much. Additionally, forming a corporation in Delaware while you intend to carry business in another state will involve more formalities.
