Sole Proprietorship: What It Is, How It Works, and How It Is Taxed

A sole proprietorship is one of the simplest ways for an individual to operate a business. It is owned and operated by one person and does not create a separate legal entity from the owner.
Before choosing this structure, it is important to understand how ownership, liability, taxes, registration, and business income work. This guide explains the basics of a sole proprietorship and how it compares with an LLC.

What Is a Sole Proprietorship?

A sole proprietorship is an unincorporated business owned by one individual. The owner and business are generally not separate legal entities.

If you conduct business activities without forming an LLC, corporation, or another formal business entity, you may operate as a sole proprietor by default. The U.S. Small Business Administration describes a sole proprietorship as a simple structure that gives the owner complete control, but the owner can also be personally liable for business debts and obligations.

A sole proprietorship can work for individuals who want to start a small business without creating a separate state business entity.

  • One Owner
  • Simple Business Structure
  • Direct Management
  • No Separate Legal Entity
  • Personal Liability

How Does a Sole Proprietorship Work?

A sole proprietor owns the business personally and generally receives the business profits directly.

The owner makes the business decisions, manages operations, and reports business income and expenses on their personal federal tax return.

Unlike an LLC or corporation, a basic sole proprietorship does not create a separate legal entity.

This simple setup can make it easier to start, but it also means the owner needs to understand the personal liability and tax responsibilities that come with the structure.

Sole Proprietorship Registration

A sole proprietorship generally does not require the same state entity formation filing as an LLC or corporation.

However, you may still need to register a business name, obtain local or state licenses, collect sales tax where applicable, or meet industry-specific requirements.

If you operate under a name other than your personal legal name, you may also need to register a DBA or assumed business name depending on your location.

Requirements vary by state and locality, so check the rules that apply to your business.

Sole Proprietorship Taxes

Understanding sole proprietorship taxes is an important part of running this type of business.

For federal income tax purposes, business income and expenses are generally reported on the owner’s individual tax return. A sole proprietor generally uses Schedule C to report profit or loss from the business.

Your taxable business profit is generally based on business income minus allowable business expenses.

You may also have estimated tax obligations during the year because taxes are generally not withheld from payments received by self-employed individuals.

State and local taxes can also apply depending on where your business operates.

Sole Proprietorship Schedule C

The sole proprietorship Schedule C is used to report income or loss from a business operated as a sole proprietor.

Schedule C is filed with Form 1040 or Form 1040-SR. It includes information about your business income and deductible business expenses.

Common information reported on Schedule C can include:

  • Gross business receipts
  • Business expenses
  • Cost of goods sold, when applicable
  • Vehicle expenses, when applicable
  • Advertising expenses
  • Business supplies
  • Professional services
  • Other eligible business expenses
If you operate more than one business, the IRS generally requires a separate Schedule C for each business activity.

Sole Proprietor Self Employment Tax

A sole proprietor self employment tax applies to eligible earnings from self-employment and generally covers Social Security and Medicare taxes. Sole proprietors report this tax separately from regular federal income tax and may also need to make estimated tax payments during the year. Tax rules can vary based on your business and income, so consider speaking with a qualified tax professional for guidance.

Sole Proprietorship Liability

One of the main things to understand before choosing this structure is liability.

A sole proprietorship does not create a separate legal entity. This means the business’s assets and liabilities are generally not legally separate from the owner’s personal assets and liabilities.

For example, business debts or certain legal claims against the business can potentially affect the owner’s personal assets.

This differs from structures such as an LLC or corporation, which generally create a separate legal entity and can provide limited liability protection.

Sole Proprietorship vs LLC

The sole proprietorship vs LLC comparison is important for anyone starting a one-owner business.

A sole proprietorship is generally simpler to start because you do not need to create a separate state business entity.

An LLC requires a state formation filing and comes with ongoing requirements, but it generally provides a legal separation between the business and its owners.

Ownership

A sole proprietorship has one owner. An LLC can have one member or multiple members.

Liability

A sole proprietor generally has personal liability for business debts and obligations. An LLC generally provides limited liability protection, although that protection has exceptions and limits.

Taxes

A sole proprietorship generally reports business income through the owner's individual tax return. A single-member LLC is generally treated as a disregarded entity for federal income tax purposes unless the owner makes a different election.

Management

A sole proprietor manages the business directly. An LLC can be member-managed or manager-managed, depending on how the company is structured.

Compliance

A sole proprietorship generally has fewer entity-level requirements. An LLC may need annual reports, registered agent maintenance, state fees, and other ongoing filings depending on the state.

Advantages of a Sole Proprietorship

A sole proprietorship can be useful for certain types of businesses and business owners.

Simple Setup

You can generally begin operating without forming a separate state business entity.

Direct Control

The owner has direct control over business decisions.

Simple Tax Reporting

Business income and expenses are generally reported through the owner's individual federal tax return using Schedule C.

Fewer Formalities

A sole proprietorship generally does not have the same corporate governance requirements as a corporation.

Easy to Change

If your business grows, you may later choose to form an LLC or corporation, although changing structures can have legal and tax consequences.

Disadvantages of a Sole Proprietorship

The simple structure also comes with considerations that should not be overlooked.

The business does not have the same legal separation from the owner that an LLC or corporation provides.

Net earnings may be subject to self-employment tax in addition to income tax.

A sole proprietorship cannot issue corporate stock, which can limit certain methods of raising capital.

Because the business is closely tied to the owner, transferring or continuing the business can require additional planning.

Business and personal assets are generally not separated by the creation of a distinct legal entity.

Is a Sole Proprietorship Right for You?

A sole proprietorship may be considered by someone starting a low-risk business, testing an idea, or operating independently.

However, the structure may not be appropriate for every business.

Think about your industry, personal liability, income, tax obligations, growth plans, and whether you expect to add owners or investors.

The SBA notes that business structure affects taxes, fundraising, paperwork, and personal liability.

If your business has higher liability risks or you want stronger separation between personal and business assets, you may want to compare an LLC or corporation before starting.

Changing From a Sole Proprietorship to an LLC

A business does not necessarily have to remain a sole proprietorship forever.

As the business grows, an owner may decide to form an LLC or corporation. The process generally involves choosing a business name, filing the appropriate formation documents, selecting a registered agent where required, and handling tax and compliance requirements.

Changing your business structure can have legal and tax consequences, so review the applicable requirements before making the change.

Starting a sole proprietorship is only the first step. You may still need licenses, permits, tax registrations, a DBA, and other business requirements.
