Definition and Features of Sole Proprietorship in California

A sole proprietorship is one of the simplest and most straightforward business structures available, not just in California, but across the United States. In essence, a sole proprietorship is an unincorporated business owned and operated by a single individual. Unlike corporations or limited liability companies (LLCs), there’s no legal distinction between the owner and the business in a sole proprietorship. This means that the business itself isn’t a separate entity; instead, the business and the owner are one and the same.

Here are some defining features of a sole proprietorship in California (source:

  • The business owners income is claimed on their individual income tax return (Form 540)
  • As a sole proprietor you are personally liable for all debts and actions of the business
  • An individual taxpayer can start a sole proprietorship
  • A married couple can report the activity of the sole proprietorship on the individual income tax return
  • A business conducted by registered domestic partners (RDP) must operate as a partnership
  • You can establish a sole proprietorship without registering with the California Secretary of State
  • Your business remains active until it’s dissolved or upon your death

Sole Proprietorship vs LLC in California

Understanding the differences between a sole proprietorship and a Limited Liability Company (LLC) is crucial for foreign companies planning to conduct business in California. Both have their distinct advantages, but they cater to different business needs and objectives.

Basic Differences Between the Two Structures

Sole ProprietorshipLLC
LiabilityThe owner bears unlimited personal liability. This means if the business incurs debts or faces a lawsuit, the owner’s personal assets (e.g., personal bank accounts, property) can be used to settle those debts or claims.The owners (known as members) have limited liability. Their personal assets are generally protected from business debts and lawsuits. This protective feature is the primary reason many entrepreneurs prefer the LLC structure.
TaxationProfits and losses from the business are reported directly on the owner’s personal income tax return. This is called pass-through taxation and ensures that business profits are only taxed once.In California, an LLC can be treated as a pass-through entity similar to a sole proprietorship, especially if it’s a single-member LLC. However, multi-member LLCs can choose to be taxed as partnerships. Additionally, LLCs in California are subject to an annual minimum franchise tax, regardless of profit.
ManagementThe management structure is straightforward. The owner makes all decisions and bears all responsibility for the business’s operations.An LLC offers more flexibility. It can be member-managed, where all members participate in the daily operations and decisions, or manager-managed, where specific members or hired managers oversee the business’s operations.

Why Might a Foreign Company Choose One Over the Other?

Sole Proprietorship Advantages

  • Simplicity: Easier and quicker to set up, especially for businesses that aim to test the Californian market without extensive initial investments.
  • Direct Tax Benefits: As previously mentioned, profits are only taxed once, potentially lowering the tax burden for businesses with moderate income.

LLC Advantages

  • Liability Protection: The protective barrier between personal and business assets is particularly attractive to foreign companies that might be unfamiliar with California’s legal landscape.
  • Flexibility in Management: Allows for a more structured approach, especially beneficial if multiple stakeholders from the foreign company are involved.
  • Professional Perception: An LLC may be viewed as a more established and committed entity in the eyes of local clients, partners, or investors.

In summary, while sole proprietorships offer an uncomplicated entry into the Californian market, LLCs provide more protection and flexibility, often more aligned with the needs of foreign companies looking to establish a robust presence. The choice largely depends on the company’s risk assessment, intended involvement in the state, and long-term objectives.

Setting Up a Sole Proprietorship in California

Operating as a sole proprietor is an attractive option for many who wish to run their own business individually in California. Based on official guidelines, here’s the step-by-step process to establish a sole proprietorship:

  1. Choose a Business Name: Even if you plan on using your own name, you must select a name for your business for tax purposes.
  1. Obtain Necessary Licenses and Permits: To legally operate your business, you’ll need the appropriate licenses and permits. This also includes obtaining zoning clearances to ensure that your business activity is allowed in the particular location you’ve chosen.
  1. Consult CalGold for Additional Information: CalGold is a valuable resource that offers specifics on business license and permit requirements based on your business type and its location. Make sure to visit their website to ensure you’ve covered all your bases.
  1. File a Fictitious Business Name Statement (optional but recommended): If you decide to operate under a name other than your own (a “Doing Business As” or DBA), you should file a fictitious business name statement with the county recorder’s office.
  1. Obtain an Employer Identification Number (EIN) (optional but recommended): While sole proprietors without employees can use their personal Social Security Number for tax purposes, obtaining an EIN from the Internal Revenue Service is often recommended, especially if you plan on hiring employees or if you’d prefer not to use your SSN for business transactions.
  1. Refer to the Employment Development Department (optional but recommended): For more details related to Employer Identification Numbers, hiring, and other employment-related queries, visit the [Employment Development Department](

Tax Implications for a Sole Proprietorship in California

Operating a sole proprietorship in California, like any other business entity, comes with its tax responsibilities. Foreign companies especially need to be acutely aware of these tax implications to ensure they remain compliant with state and federal regulations. Here’s an overview of the tax landscape for sole proprietorships in California and specific considerations for foreign entities:

Overview of Sole Proprietorship California Taxes

Income Tax

  • Sole proprietors report their business income and expenses on Schedule C (or Schedule C-EZ) of their personal federal income tax return, Form 1040.
  • The net profit or loss from this schedule is then reported on the owner’s personal tax return.
  • In California, this income will also be subject to state income tax. California has a progressive income tax system, so rates will vary based on income levels.

Self-Employment Tax

  • Sole proprietors are also subject to the federal self-employment tax, which covers Social Security and Medicare taxes.
  • It’s important to note that self-employed individuals pay both the employer and the employee portions of these taxes.

Sales and Use Tax

  • If the sole proprietorship sells tangible personal property in California, it may need to collect sales tax from customers. 
  • Proprietors must register with the California Department of Tax and Fee Administration (CDTFA) and may be required to pay regular sales tax returns.

Deductions, Credits, and Other Tax Considerations


  • Business Expenses: Common deductions for sole proprietors include home office expenses, vehicle and travel expenses, advertising costs, and any other ordinary and necessary business expenses.
  • Health Insurance: Sole proprietors can also deduct health insurance premiums for themselves and their families.


Sole proprietors may qualify for various federal and state tax credits, depending on the nature of their business and specific activities or investments they’ve undertaken. Examples include credits for hiring certain categories of employees or investing in green technologies.

Quarterly Estimated Taxes

Given that there’s no employer to withhold taxes for a sole proprietor, the IRS requires them to make estimated tax payments quarterly if they expect to owe tax of $1,000 or more when their return is filed.

For Foreign Companies

Tax Treaties

The U.S. has tax treaties with several countries that may provide reduced rates of tax or exemptions for foreign entities. It’s crucial for foreign companies to be aware of these and claim any benefits they’re entitled to. 

U.S. Withholding on Payments to Foreigners

Payments made by a U.S. business (including sole proprietors) to a foreign entity may be subject to a 30% withholding tax. However, the rate can be lower depending on tax treaties.

Permanent Establishment

Foreign companies need to determine if their activities in California give rise to a “permanent establishment.” If so, this can have significant tax implications, including the obligation to file U.S. income tax returns.

State-Specific Taxes 

Besides federal taxes, foreign companies need to be aware of any state-specific taxes or fees that apply to them in California.

In summary, while operating as a sole proprietorship in California offers simplicity in many respects, navigating the tax landscape requires careful attention, especially for foreign entities. Foreign companies should always seek expert advice from tax professionals familiar with both U.S. and international tax regulations.
