This is a question for the Nurse Entraprenure forum.
Businesses not individuals may be incorporated.
Incorporation means the business is treated as a seperate person.
You cannot protect yourself from malpractice suits by incorporation. The individual nurse is still responsible for any malprrractice within her incorporated business.
You may have a business that uses your personal name
Jane Smith, R. N. Inc. That business is not you. It is seperate from you Jane Smith, R. N. the person who practice under that corporate name. You the individual are responsible for malpractice.
Incorporating is done for serveral reasons, to protect the individual owners from excess taxation, to raise money to finace a business (for example selling shares). There is some liability protection
for those in an incorporated business however this does not include, professional malpractice by a nurse or doctor. For instance if you slip on my greasy floor and are injured or I destroy your mink coat while drycleaning it in my drycleaning business, you sue the corporation and I am protected.
However, If I injure you in a malpractice incident you will sue me the individual not the corporation. As the corporation is not responsible for malpractice I am.
Some folks form a LLC Limited Libiality Company. Which is a modern spin off of incorporation (actually a spin off of Limited Liability Partnerships) The LLC is designed for a sole propriator or partners who want the benefits of incorporation without the restrictions of a more formal corporate structure.
If your business is small and expected to remain small and depending on the tax structure in your state you might benefit by remaing a sole propriator. A LLC can give you credibility with other businesses; say, if you are marketing yourself as a one person registery.
If you are just going to "try out being in business" the expense and hassel are not worth LLC or Inc.
Contact you State Secretary who will be able to give you the requirements to incorporate or form a LLC in your state.
For specifics as to whether you can benefit by incorporating your specific business see an attorney.
Hope this helps
