A client-friendly guide to the most common business structures
Choosing a legal entity is one of the first important decisions you will make when starting a business. The right structure affects liability protection, tax reporting, payroll requirements, ownership flexibility, and how easily the business can grow.
This guide explains the most common options in plain language. It is not a substitute for legal or tax advice, but it can help you understand the key questions to discuss with your advisor before you form an entity or begin operations.
Start With Two Decisions
1. Decide whether you need limited liability protection
Many new business owners form a limited liability company, or LLC, because it can help protect the owner’s personal assets from business debts and claims. In general, if the business faces a lawsuit, debt, or other liability, the owner’s personal assets should not be the first source of payment.
An LLC is not a tax category by itself. Instead, it is a legal form that can pair with different tax classifications. For example, a single-owner LLC may report as a sole proprietorship unless the owner makes another tax election. A multi-owner LLC may report as a partnership unless the owners elect another classification.
Because liability protection matters for many businesses, owners often consider an LLC early in the planning process. The best answer depends on the business’s risks, owners, assets, and long-term goals.
2. Choose the tax and ownership structure that fits the business
After you consider liability protection, compare the main tax structures. Most new businesses choose among sole proprietorship, partnership, S corporation, or C corporation treatment. Each option works best in different circumstances.
Common Entity Options
Sole Proprietorship
A sole proprietorship is the default structure for a business with one owner that does not make another election. It is simple to operate and usually has fewer reporting requirements than other structures.
This structure often works well for a small business with modest income, limited risk, and a low volume of transactions.
Advantages
- The owner reports business activity on the owner’s individual tax return.
- The business generally does not file a separate federal income tax return.
- The owner does not need to run payroll for owner compensation.
- The owner can move money in and out of the business more easily than with some other structures.
Disadvantages
- Net earnings generally face self-employment tax for Social Security and Medicare.
- The structure may not fit a business with significant income, complex operations, or higher transaction volume.
- Without a separate liability-protective entity, the owner may face greater personal exposure.
Partnership
A partnership is the default structure for a business with two or more owners that does not make another election. Partnerships give owners flexibility, but they also require planning.
Every partnership should have a written partnership agreement. The agreement should address ownership percentages, profit and loss allocations, decision-making authority, procedures for adding or removing partners, and what happens if the partnership ends. Ideally, the owners sign this agreement before the business begins operations.
A partnership files a separate tax return, but the partnership itself generally does not pay federal income tax. Instead, each partner reports the partner’s share of business income, deductions, and credits.
Advantages
- Owners do not need to run payroll for partner compensation.
- A partnership can work well for businesses that hold real estate or other appreciating assets.
- Partners can create flexible distribution and allocation arrangements, subject to tax rules and the partnership agreement.
- Partnerships may offer more flexibility than S corporations when owners use tax losses.
Disadvantages
- Trade or business income often faces self-employment tax for the owners.
- Partnership tax reporting can become complex as the business grows.
- Ending or restructuring a partnership usually takes more planning than closing a sole proprietorship.
S Corporation
A business can elect S corporation treatment if it meets the eligibility rules. Many owners consider this option when the business earns enough profit to justify the added administrative work.
An S corporation is a pass-through tax structure. The business files its own tax return, and the owners report their share of income on their individual returns. Unlike sole proprietorships and many partnerships, S corporation income allocated to owners generally does not face self-employment tax. However, owner-employees must receive reasonable W-2 wages for the services they provide.
Advantages
- Owners may reduce self-employment tax exposure when the business has sufficient profit and pays reasonable wages.
- S corporation treatment can apply to businesses with one owner or multiple owners, subject to eligibility limits.
- The structure can work well for operating businesses with consistent income.
Disadvantages
- Owner-employees must receive reasonable W-2 wages, so the business must run payroll.
- The business must follow stricter rules for ownership, stock classes, and distributions.
- Distributions generally must follow ownership percentages.
- Basis rules may limit an owner’s ability to use losses against other income.
C Corporation
A C corporation is usually not the first choice for many small businesses, but it can make sense in specific situations. Large companies, businesses seeking outside investors, or businesses that plan to retain significant earnings may consider this structure.
A C corporation pays tax on its own income. Shareholders may also pay tax when the corporation distributes dividends. This creates the possibility of double taxation.
Advantages
- The structure can support multiple classes of stock and more complex investment arrangements.
- It may fit businesses that plan to raise capital or eventually go public.
Disadvantages
- Corporate income and shareholder dividends may both be taxed.
- The structure usually requires more formalities and administrative work.
- Many small businesses can achieve better results with another structure.
Quick Comparison
| Structure | Often best for | Key point to remember |
| Sole proprietorship | One-owner businesses with simple operations | Simple reporting, but limited tax planning and potential personal exposure if no liability-protective entity exists. |
| Partnership | Two or more owners who need flexibility | A strong partnership agreement is essential. |
| S corporation | Operating businesses with consistent profits | Potential payroll tax savings come with payroll and compliance requirements. |
| C corporation | Businesses seeking outside investors or complex capital structures | Double taxation can make this option less attractive for many small businesses. |
Before You Decide
Before forming a new business or making an election, consider these questions:
- How many owners will the business have?
- Does the business need liability protection?
- Will the business hold real estate or appreciating assets?
- How much profit do you expect the business to generate?
- Will owners need payroll?
- Do you expect to bring in investors or add owners later?
- How much administrative work can the business manage?
The right entity structure depends on the business’s facts and goals.
