Choosing the right business structure for a business in California can feel like a maze of complex legal language and intricate financial terminology. The decision between operating as a Sole Proprietorship vs S-Corp in California affects many aspects of a business, from the extent to which personal assets are exposed to risk via personal liability as a business owner in California to post-tax earnings based upon how the business entity selected is taxed.

This article seeks to provide an understandable explanation of the personal liability differences and clarify the tax differences to simplify the decision-making process for business owners in California deciding between a California Sole Proprietorship or a California S-Corp when selecting a business entity for their business.

Executive Summary: Putting the Conclusion First for Busy Entrepreneurs

Operating a business as a Sole Proprietorship in California is only a reasonable choice for business owners who do not expect significant net income, do not have (or plan to have) employees, and are not concerned with personal liability or protecting their personal assets from business risks.

A California S-Corp is the California business entity of choice for business owners who want to reduce their tax liabilities while limiting their personal liability and protecting their personal assets to the maximum extent possible in California.

An Introduction to Sole Proprietorships vs S-Corps in California

What is a Sole Proprietorship in California?

A Sole Proprietorship in California is a straightforward and uncomplicated business structure where the business and the owner are considered to be the same. In this structure, the owner reports business income and expenses on their personal tax return and is responsible for paying self-employment taxes. However, this structure does not provide any personal liability protection or personal asset protection, meaning the personal assets of the owner could be seized to satisfy any of the debts, liabilities, obligations, or legal judgments against the business.

There are minimal paperwork and regulatory requirements to start a Sole Proprietorship, and there are no filings to be made with the California Secretary of State to create or maintain a California Sole Proprietorship.

However, the simplicity and ease of setting up a Sole Proprietorship must be balanced against a lack of personal asset protection and potential for tax inefficiency before choosing a California Sole Proprietorship for doing business in California.

What is an S-Corp in California?

A California S-Corp is a separate legal entity from its owners, providing some degree of personal asset protection. This means that the personal assets of the owner are typically shielded from claims against the corporation. However, owners are still personally liable for their own actions, which liability cannot be shielded by any business entity in California.

Forming a California S-Corp involves more paperwork and ongoing regulatory requirements than a Sole Proprietorship, mostly in the form of initial and annual filings with the California Secretary of State, however, despite the complexity of formation and operation, the benefits of limited liability and potential tax efficiency make California S-Corps an attractive choice for many business owners in California.

Personal Liability in Sole Proprietorships vs S-Corps in California

In this section, we compare the personal liability aspects between Sole Proprietorships and S-Corps in California. We will discuss how these two types of business entities handle personal liability for business debts and legal claims, which is crucial for business owners who are considering which legal structure to choose for their business.

Personal Liability in a Sole Proprietorship in California

In this section, we will explore the concept of personal liability as it pertains to Sole Proprietorships in California. Particularly, we will shed light on the potential risks and implications for owners with respect to personal liability as it directly influences the risk to personal assets and financial security for an owner of a California Sole Proprietorship for the operation of their business.

Personal Liability in a California Sole Proprietorship Generally

In a California Sole Proprietorship, the owner bears unlimited personal liability for all debts, liabilities, obligations, and legal judgments associated with the business. California law does not distinguish between the owner and the business; they are considered to be the same. This means that if the business incurs debt or faces a lawsuit, the personal assets of the owner (such as their home, vehicles, investments, or personal savings) can be used to settle the debts, liabilities, obligations, or legal judgments against the business. The risk associated with this personal liability should be a significant consideration for business owners considering operating as a California Sole Proprietorship.

Personal Liability in a Sole Proprietorship with Employees

In a Sole Proprietorship, personal liability extends to the actions of employees as well. The legal principle of respondeat superior (better known as vicarious liability) applies. This means that the owner, as the employer, is held responsible for the actions of their employees performed within the course of their work duties.

For example, if an employee of a Sole Proprietorship in California does something that leads to a lawsuit, the Sole Proprietor owner may find their personal assets at risk in the ensuing legal proceedings. This risk amplifies based on the number of employees and the nature of the business.

Obtaining adequate insurance coverage can help mitigate the risk to the personal assets of the Sole Proprietor owner, however, that mitigation only extends to the limited liability protection of insurable risks and insurance policy limits.

Employment Practices Liability in a Sole Proprietorship with Employees

Employment practices liability is a significant concern for Sole Proprietorships with employees. This type of liability arises from claims made by employees alleging wrongful treatment. The scope of wrongful treatment may be discrimination (based on sex, race, age, disability, etc.), wrongful termination, harassment, retaliation, as well as countless other employment-related issues.

In the context of a Sole Proprietorship, the owner may be held personally liable for any of these claims. Because the law does not distinguish between the owner and the business entity in a Sole Proprietorship, any employment practices liability claim could potentially lead to a direct impact on the personal assets of the owner.

Any business owner, including Sole Proprietors, should consider securing employment practices liability insurance, a type of coverage that can help protect businesses against potential claims by workers, however, such coverage can be cost-prohibitive for a small business and the protection only extends to the limited liability protection of insurable risks and insurance policy limits.

Personal Liability in an S-Corp in California

This section focuses on the role of personal liability within the structure of an S-Corp in California to explore the extent to which personal assets may be shielded from personal liability to provide an overview of the protective measures offered by California S-Corps.

Personal Liability in a California S-Corp Generally

In a California S-Corp, personal liability is generally limited, which is one of the primary reasons business owners may opt for this structure. A California S-Corp is legally separate from its owners, known as shareholders, thereby offering a protective barrier for personal assets. This means that if the California S-Corp incurs debts or is sued, typically, the personal assets of the shareholder (such as their home, vehicles, investments, or personal savings) are not at risk.

It is important to note, however, that this liability protection is not absolute. Shareholders can still be held personally responsible in certain situations, such as if they provide a personal guaranty for a business loan or commercial lease, if they directly injure someone, or if they engage in fraudulent or reckless behavior.

To maintain this liability protection, the California S-Corp must adhere to certain formalities and regulations that are not required of Sole Proprietors. It is of the utmost importance for California S-Corps to meet these obligations to fully benefit from the limited liability protection offered by the California S-Corp structure.

Personal Liability in an S-Corp with Employees

Just as with Sole Proprietorships, a California S-Corp also extends its liability to the actions of its employees. The principle of respondeat superior (vicarious liability) holds true in this scenario. This means that the California S-Corp is responsible for the actions of its employees performed in the course of their employment. For example, suppose there is a lawsuit because a third party is injured by an employee driving during the course of their employment, the California S-Corp might be held responsible as well as the employee who was at fault for the accident.

However, unlike a Sole Proprietorship, the personal assets of the shareholder of the California S-Corp are generally shielded from this liability. The California S-Corp is viewed as a separate legal entity, so any lawsuits or debts incurred by the California S-Corp do not typically extend to the personal assets of its shareholder. This protection is one of the key benefits that distinguish a California S-Corp from a Sole Proprietorship.

Nevertheless, this protection is not all-inclusive. In certain situations, such as a direct injury caused by a shareholder (for instance, in the example above, if the shareholder was at fault for an accident while driving during the course of their employment) or if fraudulent or reckless behavior is exhibited, a shareholder can still be held personally responsible.

As with any business, obtaining appropriate insurance coverage can help mitigate risks associated with employee actions, and the protection provided by this insurance still only extends to the limited liability protection of insurable risks and insurance policy limits, but to the extent that such insurance provides incomplete coverage, it should be the business assets of the California S-Corp and not the assets of the shareholder at risk, which is a tremendous advantage over the lack of liability protection in a California Sole Proprietorship.

Employment Practices Liability in a California S-Corp with Employees

Within a California S-Corp, employment practices liability relates to claims arising from the employment process. A significant portion of employment practices liability issues revolve around misconduct such as discrimination (based on sex, race, age, disability, etc.), wrongful termination, sexual harassment, and retaliation.

In a California S-Corp, this liability extends to the actions of its employees under the principle of respondeat superior or vicarious liability. If an employee of the California S-Corp engages in an act that results in a lawsuit, the California S-Corp could be held responsible for the actions of its employee, but the personal assets of the shareholder are typically protected.

However, this protection is not always absolute. Situations where direct injury caused by the action or inaction of a shareholder, or fraudulent or reckless behavior, can still result in personal liability for a shareholder.

Employment practices liability insurance may be used to mitigate this risk, but to the extent that the limited liability protection of insurable risks and insurance policy limits do not cover the liability, it should be the business assets of the California S-Corp and not the assets of the shareholder at risk, which is a giant leap in protection compared to a California Sole Proprietorship.

Taxation of Sole Proprietorships vs S-Corps in California

In this section, we will compare and contrast the tax obligations for Sole Proprietorships and S-Corps in California. Understanding the taxation landscape is important for business owners as it directly impacts their personal income and overall financial health. We will explore the tax implications for each structure, including income tax, self-employment tax, and potential tax advantages, to provide a comprehensive view of how these business entities are taxed in the State of California.

Taxation of a Sole Proprietorship in California

In a Sole Proprietorship, the owner is taxed individually on all net income derived from the business. As a Sole Proprietorship does not constitute a separate legal entity, all profits and losses are reported directly on the personal income tax returns of the owner. In this section, we will delve into the intricacies of tax obligations for Sole Proprietors in California, discussing aspects such as income tax and self-employment tax pertinent to this business structure.

Federal Income Taxation of a Sole Proprietorship in California

A Sole Proprietor in California is subject to federal income tax on the net profit of their business earnings. This net profit is reported on Schedule C (Profit or Loss from Business) of the individual Internal Revenue Service Form 1040 tax return.

The federal income tax rate for Sole Proprietors is based on individual income tax rates, which are progressive. At the time of this writing, these rates range from 10% to 37%, depending on income level. These rates are applied to all taxable income, which is total income minus each applicable income tax deduction and exemption.

Sole Proprietors can also deduct business expenses related to their trade or business from their gross income. This includes costs such as office rent, utilities, equipment, advertising, and employee salaries. Additionally, the Internal Revenue Service allows Sole Proprietors to deduct health insurance premiums, half of their self-employment tax (which tax will be discussed in the next section), and contributions to retirement plans.

The federal income tax system in the United States operates on a pay-as-you-go basis, meaning that a Sole Proprietor is required to make estimated tax payments quarterly if they expect to owe at least $1,000 in federal tax for the year after subtracting withholding and refundable credits. These quarterly estimated payments cover not only federal income tax liability but also self-employment tax and alternative minimum tax obligations.

Federal Self-Employment Taxation of a Sole Proprietorship in California

Sole Proprietors in California are subject to federal self-employment tax on their business income. This tax encompasses both the Social Security and Medicare taxes for individuals who work for themselves. The current self-employment tax rate is 15.3%, with 12.4% going towards Social Security and 2.9% towards Medicare.

One of the unique aspects of the self-employment tax is that the Social Security component is only levied up to a limit that generally increases annually (on the first $160,200 of income for the 2023 tax year), whereas the Medicare component applies to all self-employment income. Additionally, if the net earnings of a Sole Proprietor exceed $200,000 for an individual or $250,000 for joint filers, there is an additional 0.9% Medicare tax.

So, for example, a business owner operating as a Sole Proprietorship may expect to pay the following amounts in self-employment tax in addition to their federal and state income tax liabilities:

$ 20,000 Net Income x 15.3% = $3,060 Self-Employment Tax

$ 40,000 Net Income x 15.3% = $6,120 Self-Employment Tax

$ 60,000 Net Income x 15.3% = $9,180 Self-Employment Tax

$ 80,000 Net Income x 15.3% = $12,240 Self-Employment Tax

$100,000 Net Income x 15.3% = $15,300 Self-Employment Tax

$120,000 Net Income x 15.3% = $18,360 Self-Employment Tax

$140,000 Net Income x 15.3% = $21,420 Self-Employment Tax

$160,000 Net Income x 15.3% = $24,480 Self-Employment Tax

These self-employment tax calculations will assume greater significance later in our discussion when we delve into the self-employment tax considerations for California S-Corps, as they will be a critical comparison point for understanding the distinct tax implications of choosing a California S-Corp over a Sole Proprietorship.

California Income Taxation of a Sole Proprietorship in California

Just like federal income tax, a Sole Proprietor in California is subject to state income tax on the net profit of their business earnings. This income is reported on the California Franchise Tax Board Form 540 California Resident Income Tax Return. The state income tax rate for Sole Proprietors is based on individual income tax rates, which are progressive. At the time of this writing, personal income tax rates in California range from 1% to 13.3%, depending on the level of income.

Sole Proprietors can deduct business expenses from their gross income on their California state tax return, similar to their federal tax return. These deductions may include office rent, utilities, equipment, advertising expenses, and employee salaries.

It is also essential to take into consideration that California does not have a standard deduction or personal exemption for individual taxpayers, unlike federal taxes. However, it does offer other credits and deductions based on specific individual circumstances.

Similar to federal taxes, Sole Proprietors are required to make estimated tax payments quarterly if they expect to owe at least $500 in tax for the year (after withholding and credits). These payments cover state income tax and any alternative minimum tax obligations.

Federal Alternative Minimum Tax for a Sole Proprietorship in California

The Federal Alternative Minimum Tax (AMT) represents a parallel tax system to the regular federal income tax in the United States. It is aimed at ensuring that individuals and corporations with substantial income cannot avoid paying a fair share of taxes through deductions and credits. Sole Proprietors in California, like Sole Proprietors elsewhere in the United States, may be subject to this tax.

The AMT calculation begins with regular taxable income and then requires the addition and subtraction of various adjustments and preferences, leading to an Alternative Minimum Taxable Income (AMTI). The AMT exemption is then subtracted from the AMTI, and the result is multiplied by the AMT tax rates of 26% or 28% to arrive at the tentative minimum tax. If the tentative minimum tax is higher than the regular tax, the difference is paid as AMT.

For Sole Proprietors, certain types of deductions that are allowable under the regular tax system could be disallowed or reduced under the AMT system, potentially resulting in a higher tax liability. Some common AMT preference items that affect Sole Proprietors include depreciation, certain medical and dental expenses, and state and local taxes.

However, the AMT system also provides an exemption amount which is designed to prevent taxpayers with income below a certain level from being subject to the AMT. This exemption amount is set annually by the Internal Revenue Service and is phased out for taxpayers at higher income levels.

As with federal income tax, Sole Proprietors are required to make estimated quarterly tax payments to cover potential AMT obligations, which should be accounted for in their ongoing tax planning.

California Alternative Minimum Tax for a Sole Proprietorship in California

Just like its federal counterpart, the California Alternative Minimum Tax (AMT) is a parallel tax system designed to ensure that taxpayers, including Sole Proprietors, pay at least a minimum amount of tax. It targets those who may otherwise be able to lower their tax obligations through various credits and deductions. The AMT system requires the computation of taxable income with the consideration of certain adjustments and tax preference items.

For Sole Proprietors, the California AMT calculation begins with regular taxable income, with certain additions and subtractions, leading to Alternative Minimum Taxable Income (AMTI). The AMT exemption is then subtracted from the AMTI, and the result is multiplied by the AMT tax rate, currently set at 7% for individuals, to arrive at the tentative minimum tax. If the tentative minimum tax is higher than the regular tax, the difference is paid as AMT.

Certain types of deductions that are allowable under the regular tax system could be disallowed or reduced under the California AMT system, potentially resulting in a higher tax liability for Sole Proprietors. Some common state AMT preference items include long-term contracts, depletion, and pollution control facilities.

Additionally, the California AMT provides an exemption amount designed to prevent taxpayers with income below a specific level from being subject to the AMT. However, this exemption amount is phased out for taxpayers with higher income levels. As part of their ongoing tax planning, Sole Proprietors should be aware of their potential AMT obligations and make corresponding estimated quarterly tax payments.

Taxation of an S-Corp in California

In contrast to Sole Proprietorships, a California S-Corp has a different taxation structure. This section will examine the specific tax implications and obligations for a California S-Corp. We will explore the distinct state and federal income tax treatments, discuss employment tax benefits, and offer a comparison with the taxation of Sole Proprietorships detailed in the previous sections.

Federal Income Taxation of an S-Corp in California

For a California S-Corp, the income tax treatment differs significantly from that of Sole Proprietorships.

A California S-Corp does not pay income taxes at the corporate level under the federal rules. Instead, it operates as a pass-through entity where the income, deductions, and credits pass through to shareholders. Each shareholder then reports their share of the net income or net loss of the California S-Corp on their individual tax returns, according to their percentage ownership of the California S-Corp shares and at their individual income tax rates (the same rates discussed for Sole Proprietors in the Federal Income Taxation of a Sole Proprietorship in California section, above). For federal income tax purposes, and negating income tax deductions from the payment of employment taxes, the federal income tax paid by a Sole Proprietor and a shareholder of a California S-Corp are equivalent.

Restrictions on shareholders of a California S-Corp are in place to maintain its status as an S Corporation. A California S-Corp is limited to one hundred shareholders. These shareholders must be United States citizens or permanent residents of the United States. Further, other corporations, partnerships, and certain trusts cannot own shares in a California S-Corp. There can only be one class of stock, meaning that all shareholders have the same rights to profits and assets.

Despite the restrictions, S Corporation taxation is often the preferred choice for most business owners.

Federal Self-Employment Taxation of an S-Corp in California

California S-Corps are not subject to self-employment taxes. Yes, you read that correctly. Read that again if necessary.

One of the major advantages of a California S-Corp is the ability to eliminate self-employment taxes. This is because shareholders who are also employees of the corporation are required to pay themselves a reasonable salary, which is subject to standard employment taxes, but not self-employment taxes.

The term “reasonable salary” is not explicitly defined by the IRS, but guidelines suggest it should reflect the market rate for similar services provided in the industry. This salary is considered an expense for the California S-Corp and is, therefore, deducted from its income.

The employer and employee contributions to standard employment taxes is the same 15.3% as self-employment taxes paid by Sole Proprietors, but the benefit of replacing self-employment taxes with standard employment taxes paid only on a reasonable salary to a shareholder who is also an employee of the California S-Corp, and any remaining income of the corporation after the payment of reasonable salary can be distributed to the shareholders without being subjected to self-employment taxes. This could mean significant tax savings for shareholders of a California S-Corp.

There are a few different methods of determining what is a reasonable salary, and these should be discussed with a tax advisor. However, drawing upon the self-employment tax calculations provided in the Federal Self-Employment Taxation of a Sole Proprietorship in California section, above, see the following table and compare the savings between the self-employment tax of a Sole Proprietorship and the standard employment tax of a California S-Corp:

$12,000 Reasonable Salary on $20,000 Net Income x 15.3% = $1,836 Standard Employment Tax (Savings of $1,224 Compared to Self-Employment Tax)

$24,000 Reasonable Salary on $40,000 Net Income x 15.3% = $3,672 Standard Employment Tax (Savings of $2,448 Compared to Self-Employment Tax)

$36,000 Reasonable Salary on $60,000 Net Income x 15.3% = $5,508 Standard Employment Tax (Savings of $3,672 Compared to Self-Employment Tax)

$48,000 Reasonable Salary on $80,000 Net Income x 15.3% = $7,344 Standard Employment Tax (Savings of $4,896 Compared to Self-Employment Tax)

$60,000 Reasonable Salary on $100,000 Net Income x 15.3% = $9,180 Standard Employment Tax (Savings of $6,120 Compared to Self-Employment Tax)

$60,000 Reasonable Salary on $120,000 Net Income x 15.3% = $9,180 Standard Employment Tax (Savings of $9,180 Compared to Self-Employment Tax)

$60,000 Reasonable Salary on $140,000 Net Income x 15.3% = $9,180 Standard Employment Tax (Savings of $12,240 Compared to Self-Employment Tax)

$60,000 Reasonable Salary on $160,000 Net Income x 15.3% = $9,180 Standard Employment Tax (Savings of $15,300 Compared to Self-Employment Tax)

A tax advisor should be consulted regarding setting a reasonable salary, although for many business owners, $60,000 could be deemed a maximum reasonable salary.

The 0.9% Additional Medicare Tax still applies under standard employment taxes; however, this is another way in which a California S-Corp can be advantageous. By setting a reasonable salary for shareholder-employees, it is possible to keep their income below the income thresholds that trigger the Additional Medicare Tax.

California Income Taxation of an S-Corp in California

Income from an S-Corp in California is passed through to the shareholder who then reports it on their individual income tax returns. This is similar to the federal treatment, with the income being taxed at the individual California income tax rates, ranging from 1% to 13.3%, depending on the income bracket.

California S-Corps are also subject to a 1.5% franchise tax on their net profit, with a minimum tax of $800 annually paid to the California Franchise Tax Board. This tax is payable regardless of whether the corporation is active, inactive, operates at a loss, or files a return for a short period of less than 12 months.

For California income tax purposes, and negating income tax deductions from the payment of employment taxes, the federal income tax paid by a Sole Proprietor and a shareholder of a California S-Corp are equivalent. The additional franchise tax of 1.5% subject to a $800 should be weighed against the savings created by standard employment taxes on the salary of an employee-shareholder of a California S-Corp and their expected net income and reasonable salary.

Federal Alternative Minimum Tax for an S-Corp in California

There is no federal Alternative Minimum Tax (AMT) for California S-Corps.

California Alternative Minimum Tax for an S-Corp in California

There is no California Alternative Minimum Tax (AMT) for California S-Corps.

Making a Final Decision Between Sole Proprietorship vs S-Corp in California

Operating a business as a Sole Proprietorship in California is only a reasonable choice for business owners who:

1. Do not expect significant net income;

2. Do not have (or plan to have) employees; and

3. Are not concerned with personal liability or protecting their personal assets from business risks.

A California S-Corp is the California business entity of choice for business owners who cannot agree with all three of the statements above and instead want to reduce their tax liabilities while limiting their personal liability and protecting their personal assets to the maximum extent possible in California.
