Limited liability companies allow for a large variety of management structures based on your specific needs. Management structures for S-Corps are largely dictated by state and federal law. Management schemas for C-Corps are largely dictated by state and federal law. NPOs need to follow strict management laws to guard their non-profit status. Since Sole Proprietorships have only one member, there is no management structure.
Minnesota nonprofit corporations are not required to use any of these words; for business corporations, they must use "corporation", "incorporated", or "limited", or shall contain an abbreviation of one or more of these words, or the word "company" or the abbreviation "Co." if that word or abbreviation is not immediately preceded by the word "and" or the character "&" Chapter 302A, Section 302A.115 Minnesota Statutes (for Business Corporations); Chapter 317A, Section 317A.115 Minnesota Statutes (for non-profit corporations)
For federal tax purposes, the Internal Revenue Service has separate entity classification rules. Under the tax rules, an entity may be classified as a corporation, a partnership, a cooperative or a disregarded entity. A corporation may be taxed as either a C corporation or elect to be treated as a Subchapter S corporation. A disregarded entity has one owner (or a married couple as owner) that is not recognized for tax purposes as an entity separate from its owner. Types of disregarded entities include single-member LLCs; qualified sub-chapter S subsidiaries and qualified real estate investment trust subsidiaries. A disregarded entity's transparent tax status does not affect its status under state law. For example, for federal tax purposes, a sole-member LLC (SMLLC) is disregarded, so that all its assets and liabilities are treated as owned by its single member. But under state law, an SMLLC can contract in its own name and its owner is generally not personally liable for the debts and obligations of the entity. To be recognized as a Cooperative for tax purposes Cooperatives must follow certain rules under Sub Chapter T of the Internal Revenue Code.

Limited liability companies can raise money via banks and investors but cannot sell stocks. S-Corps can get loans from banks, as well as distribute stock to up to 100 people. C-Corps have the easiest time raising capital as there is no cap on how many people can own stock. Non-Profits can both get loans and receive tax-deductible donations. Sole Proprietorships can occasionally receive bank loans but cannot sell stocks.
Depending on elections made by the LLC and the number of members, the IRS will treat an LLC as either a corporation, partnership, or as part of the LLC’s owner’s tax return (a “disregarded entity”). Specifically, a domestic LLC with at least two members is classified as a partnership for federal income tax purposes unless it files Form 8832 and affirmatively elects to be treated as a corporation. For income tax purposes, an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and elects to be treated as a corporation. However, for purposes of employment tax and certain excise taxes, an LLC with only one member is still considered a separate entity.
