## Definition

A business entity is a legally recognized organization formed to conduct commercial activity. Common forms in the U.S. include sole proprietorship, partnership, limited liability company (LLC), S-corporation, and C-corporation — each with distinct liability protection, tax treatment, governance, and reporting requirements.

## Key takeaways

- Choice of entity affects liability, taxation, ownership transferability, and ability to raise capital.
- LLCs are taxed by default as sole proprietorships or partnerships but can elect S-corp or C-corp treatment.
- C-corporations face two-tier (corporate + shareholder) taxation; pass-through entities do not.
- Entity choice should be reviewed periodically, especially before major financing or sale events.

## How Olomon thinks about this

_The following section is Olomon's first-party perspective, informed by our work building a financial system of record. It is intentionally separated from the neutral definitional content above._

Most households underestimate how much of their wealth lives inside entities — LLCs that hold real estate, S-corps that hold operating businesses, partnerships for passive investments. Olomon treats each entity as a node in your record, with its own balance sheet, ownership chart, governance documents, and beneficiaries, so the entire enterprise picture is connected to the people behind it.

## In-depth definition

Choosing the right entity — and operating it cleanly — is one of the most consequential decisions in personal and business finance. The right choice depends on liability exposure, expected income, capital needs, ownership structure, and exit plans. The wrong choice can create double taxation, blocked capital raises, or pierced liability shields.

## Frequently asked questions

### Do I need a business entity to operate a business?

No. You can operate as a sole proprietor without forming any entity. But forming an LLC or corporation provides liability separation and may unlock tax efficiencies as the business grows.
