The startup cost for an RN consulting service is relatively low. As an RN, you are licensed to practice as a nurse; therefore, you are not required to start a sole proprietorship, limited liability company (LLC), or a corporation. Even if you are providing services as an LLC or corporation, you are personally responsible for your actions as a nurse and legal nurse consulting is nursing. The LLC and/or corporation does not relieve you of responsibility and/or protect your personal assets. Although it is not required, the NNBA recommends that you incorporate your business to protect your personal assets and take advantage of many tax deductions only available to incorporated small businesses.
