An S-Corporation (S-Corp) is a business structure commonly used by contractors who want corporate liability protection with pass-through tax treatment. A business must first form a corporation and then elect S-Corporation tax status with the IRS.
For federal income tax purposes, S-Corporations are generally taxed as pass-through entities. This means profits and losses are reported on the owners’ personal tax returns rather than being taxed at the corporate level.
S-Corporations may offer potential savings on self-employment taxes. Owners who work in the business are required to pay themselves a reasonable salary subject to payroll taxes, while remaining profits may be taken as distributions that are generally not subject to self-employment tax.
To form an S-Corporation in California, you must file incorporation documents with the California Secretary of State, obtain an EIN, and elect S-Corporation status with the IRS. When properly maintained, this structure helps separate personal assets from business liabilities and is subject to California franchise taxes and state filing requirements.





To qualify for S-Corporation tax status, your business must meet IRS eligibility requirements, including:
Once these requirements are met, S-Corporation status is elected by filing IRS Form 2553 after the corporation is formed
In an S-Corporation, ownership is represented by shares of stock.
In practice, all owners of an S-Corporation are shareholders.
Yes. An S-Corporation may have a single shareholder, and many S-Corporations are owned by one individual.
No. There is no minimum ownership percentage required. Shareholders may own varying percentages of the corporation, as long as there is only one class of stock.
S-Corporation shareholders must meet IRS eligibility requirements. Generally, shareholders must be U.S. citizens or U.S. resident aliens. Eligibility is determined by tax residency status rather than the type of taxpayer identification number alone. It is recommended to consult a tax professional to confirm eligibility.
S-Corporations typically have officer roles such as President, Secretary, and Treasurer. In many small or single-owner S-Corporations, one individual may hold all officer positions.
An S-Corporation generally does not pay federal income tax at the business level. Instead, profits and losses pass through to the owners' personal tax returns. Owners who work in the business are required to pay themselves a reasonable salary that is subject to payroll taxes, while additional profits may be taken as distributions that are generally not subject to self-employment tax.
A C-Corporation (C-Corp) is the default corporate structure for California contractors unless S-Corporation status is elected. It is commonly used by businesses that want flexible ownership options and plan for long-term growth.
C-Corporations pay federal income tax on business profits. If profits are distributed as dividends, shareholders may also pay tax on those dividends, commonly referred to as double taxation.
This structure allows for unlimited shareholders and multiple classes of stock, which can make it attractive for contractors looking to reinvest profits or bring on investors.
To form a C-Corporation in California, you must file Articles of Incorporation with the California Secretary of State and obtain an Employer Identification Number (EIN) from the IRS. C-Corporations are subject to ongoing California filing requirements and an annual franchise tax. When corporate formalities are properly maintained, this structure helps separate personal assets from business liabilities.








To operate as a C-Corporation in California, your business must meet the following general requirements:
After incorporation, the business must obtain an Employer Identification Number (EIN) from the IRS and comply with applicable federal and California tax and filing requirements.
Yes. A C-Corporation may be formed with a single shareholder, and many C-Corporations are owned by one individual.
No. There is no minimum ownership percentage required. Shareholders may own varying percentages of a C-Corporation.
Yes. C-Corporations may have U.S. or foreign shareholders. Shareholders who are not eligible for a Social Security Number may use an Individual Taxpayer Identification Number (ITIN) to meet U.S. tax filing requirements, subject to IRS rules.
Shareholder tax obligations vary based on residency and individual circumstances.
C-Corporations typically have officer roles such as President, Secretary, and Treasurer. In many small or single-owner C-Corporations, one individual may hold all officer positions.
A C-Corporation is subject to federal income tax at the corporate level. If profits are distributed to shareholders as dividends, those dividends may also be taxed on the shareholders’ personal tax returns, commonly referred to as double taxation. Depending on how profits are retained or distributed, this structure may allow for reinvestment of earnings and other tax planning considerations.
Tax treatment depends on how profits are distributed and individual circumstances.
The primary difference is how the two entities are taxed. A C-Corporation is subject to federal income tax at the corporate level, and shareholders may also be taxed on dividends they receive. An S-Corporation, by contrast, is generally taxed as a pass-through entity, meaning profits and losses are reported on the shareholders’ personal tax returns rather than being taxed at the corporate level.
No. You do not need a personal or business address in California to form a C-Corporation, as long as you designate a California Agent for Service of Process, which is an individual or company authorized to receive legal and official documents on behalf of the corporation.

An LLC is a popular business structure for contractors who want personal liability protection with flexible management and tax options. When properly maintained, an LLC helps separate personal assets from business debts and obligations.
By default, LLCs are generally taxed as pass-through entities, meaning profits and losses are reported on the members’ personal tax returns rather than being taxed at the business level. LLCs may also elect different tax treatment with the IRS depending on business needs.
LLCs offer operational flexibility and generally have fewer ongoing compliance requirements than corporations, making them a practical option for contractors seeking simplicity.
To form an LLC, you must file Articles of Organization with the California Secretary of State, obtain an Employer Identification Number (EIN) from the IRS, and meet applicable state requirements. In California, LLCs are subject to ongoing state filing requirements and an annual franchise tax or fee.







$100,000 LLC Employee/Worker Bond
Contractor LLCs licensed by the California Contractors State License Board (CSLB) must maintain an additional $100,000 LLC Employee/Worker Bond (in addition to the standard $25,000 contractor license bond). This bond is required for the issuance, renewal, reactivation, or reinstatement of an LLC contractor license and is intended to protect employees or workers if the LLC fails to pay wages, benefits, or other required contributions. (B&P Code § 7071.6.5)
$1 Million Liability Insurance Minimum
The CSLB also requires contractor LLCs to carry commercial general liability insurance with a minimum aggregate limit of $1 million for licensees with five or fewer personnel of record. An additional $100,000 in coverage is required for each additional member of the personnel of record, up to a total required coverage limit of $5 million. (B&P Code § 7071.19)
To form a California (domestic) LLC, the following general requirements apply:
Businesses formed outside California are required to register as foreign LLCs with the California Secretary of State to obtain a California contractor license. See our Foreign Corporations & LLCs page for more information.
By default, an LLC is generally taxed as a pass-through entity, meaning profits and losses are reported on the members’ personal tax returns rather than being taxed at the business level. Members pay income tax on their share of the LLC’s earnings, and members who actively participate in the business may also be subject to self-employment taxes. LLCs may elect different tax treatment with the IRS depending on business needs.
The main difference is how they are structured and taxed. Corporations follow a more formal structure and may be taxed as either a C-Corporation (taxed at the corporate level) or an S-Corporation (generally taxed as a pass-through entity). LLCs offer more flexible management and are generally taxed as pass-through entities by default.
For California contractors, another key difference is that the CSLB requires LLCs to carry additional protections, including an LLC Employee/Worker Bond and commercial general liability insurance, which are not required for all corporation types.
No. You do not need a personal or business address in California to form a California LLC. However, you are required to designate a California Agent for Service of Process, which is an individual or company authorized to receive legal and official documents on behalf of the LLC and must have a physical California address.

In an LLC, members are the owners of the business. Managers handle the day-to-day operations and may be appointed by the members. Members can also serve as managers, depending on how the LLC is set up.
Yes. An LLC may be formed by a single individual and operated as a single-member LLC.
No. There is no minimum ownership percentage required. Members may own varying percentages of the LLC.
If your corporation or LLC was formed outside of California and you plan to conduct business in California, you are generally required to register with the California Secretary of State as a foreign corporation or foreign LLC.
This process allows your existing out-of-state business to legally operate in California without creating a new entity. Foreign registration is similar to forming a new business in California, but it includes additional requirements.
To register, you must file the appropriate foreign registration form with the California Secretary of State and provide a Certificate of Good Standing (or equivalent document) from the state where your business was originally formed.

No. You do not need a personal or business address in California to register a foreign corporation or LLC. However, you are required to designate a California Agent for Service of Process, which is an individual or company authorized to receive legal and official documents on behalf of the entity and must have a physical California address.

A Certificate of Good Standing is a document issued by the state where your business was originally formed. It confirms that your business is active and in good standing with the state, meaning required filings have been made and the entity is authorized to do business under that state’s rules.
Yes. Foreign corporations and LLCs may have multiple owners. Corporations may have multiple shareholders, and LLCs may have multiple members. Ownership percentages may vary depending on how the entity is structured and documented. Eligibility and tax requirements may also vary based on the owners’ residency and entity type.
An Agent of Service of Process, also known as a Registered Agent, is a person or entity designated to receive legal documents on behalf of the corporation or LLC. This role is crucial for ensuring that the business can be properly served with legal notices and other important documents.
Foreign corporations and LLCs are generally subject to California taxes on income derived from business conducted in the state. The type and amount of tax depend on the entity’s structure and tax classification.
In addition to income taxes, foreign corporations and LLCs may be subject to California’s annual franchise tax and ongoing filing requirements. Tax obligations vary based on business activity, revenue, and tax elections.
Because tax treatment depends on individual circumstances, it is advisable to consult a qualified tax professional regarding your specific obligations.
