Risks and Liabilities

In large part, the best ownership structure for your business depends on the type of services or products it will provide. If your business will engage in risky activities -- for example, trading stocks or repairing roofs -- you'll almost surely want to form a business entity that provides personal liability protection ("limited liability"), which shields your personal assets from business debts and claims. A corporation or a limited liability company (LLC) is probably the best choice for you.

Formalities and Expenses

Sole proprietorships and partnerships are easy to set up -- you don't have to file any special forms or pay any fees to start your business. Plus, you don't have to follow any special operating rules.

LLCs and corporations, on the other hand, are almost always more expensive to create and more difficult to maintain. To form an LLC or corporation, you must file a document with the state and pay a fee, which ranges from about $40 to $800, depending on the state where you form your business. In addition, owners of corporations and LLCs must elect officers (usually, a president, vice president, and secretary) to run the company. They also have to keep records of important business decisions and follow other formalities.

If you're starting your business on a shoestring, it might make the sense to form the simplest type of business -- a sole proprietorship (for one-owner businesses) or a partnership (for businesses with more than one owner). Unless yours will be a particularly risky business, the limited personal liability provided by an LLC or a corporation may not be worth the cost and paperwork required to create and run one.
