Business Entities

Quick Answer

Business entities differ on two axes: who is liable for debts, and how profits are taxed. General partnerships and sole proprietorships give no liability protection. LLCs, S-corporations, and C-corporations protect all owners. Only C-corporations face double taxation; every other entity here defaults to pass-through taxation, though an LLC can elect S- or C-corp treatment instead.

The exam pairs each entity with its liability and tax profile, then asks which entity fits a scenario. Learn the pattern once and most business-entity questions become a lookup rather than a puzzle.


What Is a General Partnership?

  • Two or more persons carrying on a business for profit
  • All partners have unlimited personal liability for partnership debts
  • Income and losses pass through to partners' personal tax returns (no entity-level tax)
  • Each general partner typically has equal management authority, unless the partnership agreement states otherwise
  • Fiduciary duty exists between general partners (duty of loyalty, duty of care)
  • The partnership dissolves upon the death or withdrawal of a general partner, unless the agreement provides otherwise

How Does a Limited Partnership Differ From a General Partnership?

  • Requires at least one general partner (GP) and one limited partner (LP)
  • GP: unlimited liability, manages the business, owes fiduciary duties
  • LP: liability limited to the amount invested, no management authority
  • Pass-through taxation; income and losses flow to partners' personal returns
  • Liquidation priority: creditors first, then LPs, then the GP last

Exam Tip: Gotchas

  • Limited partners are generally passive. Exercising control over the business may create personal-liability exposure, but the consequence depends on the governing partnership statute and the conduct involved.
  • The general partner always has unlimited personal liability in a limited partnership.

How Does an LLC Combine Partnership and Corporate Benefits?

  • Hybrid entity combining partnership tax benefits with corporate liability protection
  • All members have limited liability, so personal assets are protected from business debts
  • Default tax treatment is pass-through: a single-member LLC is taxed as a sole proprietorship, a multi-member LLC as a partnership
  • Can elect to be taxed as an S-corp or C-corp
  • Members can participate in management without losing liability protection, unlike LPs
  • More flexible management structure than corporations, governed by an operating agreement
  • No limit on the number of members; members can be individuals, corporations, other LLCs, or foreign entities

How Is a C-Corporation Taxed and Managed?

  • Separate legal entity from its owners (shareholders)
  • Limited liability for all shareholders
  • Subject to double taxation:
    1. The corporation pays corporate income tax on profits
    2. Shareholders pay personal income tax on dividends received
  • Can have unlimited shareholders of any type
  • Managed by a board of directors elected by shareholders
  • Perpetual existence: not affected by the death or transfer of shareholders
  • Can issue multiple classes of stock (common and preferred)
  • Can retain earnings for business use, subject to an accumulated earnings tax if excessive

How Does an S-Corporation Differ From a C-Corporation?

  • Special tax election under Subchapter S of the Internal Revenue Code
  • Pass-through taxation: income and losses flow to shareholders' personal returns, avoiding double taxation
  • Limited liability for all shareholders, same as a C-corp
  • Restrictions:
    • Maximum of 100 shareholders
    • Individual shareholders must be U.S. citizens or resident aliens (no foreign individual shareholders); eligible trusts, estates, and qualifying tax-exempt organizations are separate eligible-holder categories
    • Only one class of stock permitted
    • Shareholders must be individuals, certain trusts, or estates; corporations and partnerships generally cannot be shareholders, though certain tax-exempt organizations such as qualified retirement plans and charities may hold shares

Exam Tip: Gotchas

  • Double taxation = C-corporation only. Every other entity here defaults to pass-through taxation, though an LLC can elect S- or C-corp treatment instead.
  • 100 shareholder limit = S-corporation only. Among the multi-owner entities (partnerships, LLCs, corporations), no other type caps owners.

C-Corp vs. S-Corp comparison:

FeatureC-CorporationS-Corporation
TaxationDouble taxation (entity + shareholder)Pass-through (shareholder only)
ShareholdersUnlimited, any typeMax 100; U.S. individuals, certain trusts/estates, and qualifying tax-exempt organizations only (no corporations or partnerships)
Stock classesMultiple classes allowedOne class only
Foreign ownersPermittedNot permitted
Tax lossesTrapped at corporate levelFlow through to shareholders

Exam Tip: Gotchas

When a question asks which entity provides BOTH liability protection AND pass-through taxation, the answers are LLC and S-corporation. General partnerships have pass-through taxation but no liability protection. C-corporations have liability protection but double taxation.

What Should You Check on Exam Day?

  • Match liability first, then taxation. General partnerships and sole proprietorships: no protection. LLC, S-corp, C-corp: protection for all owners.
  • Only a C-corporation double-taxes. Every other entity here defaults to pass-through taxation, though an LLC can elect S- or C-corp treatment instead.
  • LLC and S-corp are the entities that give both liability protection and pass-through taxation together.
  • S-corp restrictions travel as a set: 100 shareholders, U.S. individuals/eligible trusts/estates/qualifying tax-exempt organizations only, one stock class, no corporate or partnership shareholders.
