The California corporate tax rate for 2025 is generally 8.84% for C corporations, applied to net taxable income attributable to California. That rate is separate from federal corporate income tax and from the rules governing S corporations and LLCs.
Key Takeaways
- California's 2025 C corporation tax rate is 8.84% of net taxable income attributable to the state.
- The 8.84% rate is not a general gross receipts tax. Deductions and California allocation or apportionment rules affect the tax base.
- California S corporations generally pay 1.5% of net income, subject to an $800 minimum franchise tax.
- LLCs generally owe an $800 annual tax and may owe an additional fee when California annual income reaches $250,000.
- C corporations and S corporations generally face an $800 minimum franchise tax after their first taxable year, even during a loss year.
- The 21% federal corporate tax rate is separate from California's 8.84% rate, so a C corporation may owe both taxes.
California Corporate Tax Rate 2025: The 8.84% Rule
The California corporate income tax rate for 2025 is 8.84% for a standard C corporation. California applies that percentage to the corporation's net taxable income attributable to the state, not automatically to its total revenue or gross receipts.
California describes the charge as a franchise tax when a corporation is doing business in the state. A corporation that is not doing business in California but receives California-source income may instead be subject to the corporation income tax. The standard rate is 8.84% in either situation. Different rates apply to financial corporations, so banks and similar businesses should check the rules specific to their classification.
The tax base begins with income rather than cash collected from customers. Ordinary business deductions, state adjustments, and rules assigning income to California can change the final amount. A corporation operating only in California may have a relatively direct calculation. A corporation selling or operating in several states must determine how much income California may tax.
The 8.84% figure also does not include federal corporate tax, sales and use tax, payroll obligations, property tax, or industry-specific charges. Those obligations arise under separate rules. The distinction matters when budgeting because multiplying revenue by 8.84% usually does not produce the corporation's California tax bill.
2025 California Business Tax Rates at a Glance
Entity classification controls the applicable California business tax rate. A legal entity and its federal tax classification are related but distinct. For example, an LLC may remain a partnership for tax purposes or elect corporate treatment.
| Entity or classification | California tax base | Entity-level obligation | Owner-level consideration | Gross-receipts-based fee |
|---|---|---|---|---|
| C corporation | Net taxable income attributable to California | 8.84%, generally subject to an $800 minimum franchise tax after the first taxable year | Shareholders may owe tax if the corporation distributes taxable dividends | No general C corporation gross receipts tax |
| S corporation | Net income | 1.5%, generally subject to an $800 minimum franchise tax after the first taxable year | Shareholders report their shares of pass-through income | No LLC-style gross receipts fee |
| LLC taxed as a partnership or disregarded entity | Pass-through income, plus California annual income for fee purposes | $800 annual tax, plus an LLC fee when California annual income reaches $250,000 | Members or the owner generally report pass-through income | $900 to $11,790, depending on the applicable income tier |
The LLC fee tiers are $900 for California annual income from $250,000 through $499,999, $2,500 from $500,000 through $999,999, $6,000 from $1 million through $4,999,999, and $11,790 at $5 million or more. An LLC taxed as a corporation follows the rules for its elected classification instead of the default pass-through rules.

How to Calculate California Corporate Tax on $100,000
A C corporation with $100,000 of California net taxable income would have a basic state tax calculation of $8,840. The calculation is $100,000 multiplied by 8.84%. This hypothetical assumes the entire $100,000 is taxable by California and ignores credits, state adjustments, prior-year items, and special industry rules.
The answer changes if $100,000 refers to revenue, accounting profit, federal taxable income, or income earned across several states. Revenue is not the standard C corporation tax base. The corporation generally subtracts allowable expenses and applies required tax adjustments before determining net taxable income. A multistate corporation must also determine the portion attributable to California.
An S corporation with $100,000 of net income would generally calculate $1,500 of California entity-level tax at the 1.5% rate. Its shareholders would also report their respective shares of pass-through income on their individual returns. The shareholders' personal tax depends on their individual circumstances, so the entity-level calculation does not show the total combined burden.
An LLC with $100,000 of annual income would generally remain below the $250,000 threshold for the additional LLC fee, but the $800 annual tax may still apply. Its owner-level tax treatment would depend on whether it is disregarded, taxed as a partnership, or has elected corporate status.
California S Corp Tax Rate and Pass-Through Income
The California S corp tax rate for 2025 is 1.5% of net income. California recognizes a valid federal S election, but it still imposes an entity-level tax on the S corporation. This differs from the federal approach, under which an S corporation generally passes taxable income through without paying the standard federal corporate income tax.
An S corporation's shareholders report their shares of income even when the company retains cash instead of distributing it. The distinction between taxable income and cash distributions can create planning issues for owners who need funds to pay personal tax. For additional context, see how S corporation retained earnings are treated.
The 1.5% tax is not the only consideration when choosing S status. Eligibility restrictions, payroll practices, reasonable compensation, ownership plans, and financing needs may affect the decision. A company must also make and maintain the required federal election before California will treat it as an S corporation.
An S corporation can be attractive when a profitable owner-operated business wants pass-through taxation and corporate liability protection. It is not automatically cheaper than an LLC or C corporation. Compare expected net income, gross receipts, owner compensation, planned distributions, and future investment before changing classification. California-specific formation and compliance considerations are covered in California S corporation tax guidance.
Minimum Franchise Tax and Loss-Year Obligations
California corporations generally owe an $800 minimum franchise tax after their first taxable year. This minimum can apply even when a C corporation or S corporation has no profit or reports a loss. The minimum is not an additional $800 when the percentage-based tax is already higher. Instead, the corporation generally pays the larger applicable amount.
Newly incorporated or newly qualified corporations generally do not owe the minimum franchise tax for their first taxable year. That first-year rule does not eliminate tax based on income. A new C corporation with taxable income may still owe tax at 8.84%, and a new S corporation with net income may still owe tax at 1.5%.
LLCs follow different rules. The temporary first-year annual-tax relief that applied to certain LLCs organized or registered during earlier years does not cover an LLC formed in 2025. A California LLC should therefore budget for the $800 annual tax unless a specific exemption applies.
Dissolving the business informally does not necessarily end its obligations. An entity that remains active on state records, continues doing business, or fails to complete required cancellation or dissolution steps may continue to face filing and payment issues. Businesses should coordinate final tax filings with the legal documents used to wind up the entity.
Do California C Corporations Pay a Gross Receipts Tax?
California does not impose a general state-level gross receipts tax on C corporations merely because they have revenue. The standard 8.84% corporate rate applies to net taxable income attributable to California. This is the main misconception behind descriptions of the California corporate tax as a tax on gross income.
Separate charges can still depend on receipts or sales. Most notably, an LLC taxed under the default pass-through rules may owe an additional fee based on California annual income once it reaches $250,000. That LLC fee is not the 8.84% C corporation tax and does not convert California's corporate income tax into a general gross receipts tax.
A corporation may also have sales and use tax responsibilities if it sells taxable goods or makes taxable transactions. Sales tax collected from customers is different from corporate income tax. Employers may face payroll-related obligations, and businesses that own property may owe locally administered property taxes. Industry-specific taxes and local requirements can also apply.
For planning purposes, separate each obligation by its tax base. Corporate income tax uses net taxable income. An LLC fee uses the applicable California annual-income tier. Sales tax generally concerns taxable sales. Payroll obligations relate to wages. Treating all of these as one California corporate tax rate can substantially distort forecasts and entity comparisons.
Multistate Corporations, Nexus, and California Income
An out-of-state corporation may have California filing and tax obligations even if it was incorporated elsewhere. Incorporation in Delaware, Nevada, or another state does not prevent California from taxing a company that does business in California or receives taxable California-source income.
Nexus is the connection that permits California to impose a tax or filing requirement. Physical offices, employees, property, transactions, and California sales can all require review. The applicable standards depend on the tax and the company's facts, so an online or service business should not assume it is outside California's reach merely because it lacks a traditional storefront.
When a corporation earns income in several states, allocation and apportionment rules determine the amount attributable to California. California generally uses sales-based apportionment for many businesses, but special rules may apply to particular industries and types of income. The location of customers and the rules for sourcing services or intangible property can therefore affect the calculation.
A corporation with foreign affiliates may also need to consider California's worldwide combined reporting framework and the availability of a Water's Edge election. That election can limit which foreign entities and income enter the combined report, but it carries procedural requirements and is generally binding for a specified period. Review the current election instructions before relying on it.

Choosing Between a C Corporation, S Corporation, and LLC
The best entity depends on more than the headline California business tax rate. A C corporation may fit a company that expects institutional investment, wants multiple classes of stock, or plans to retain earnings for growth. The trade-off is entity-level taxation and possible shareholder tax when profits are distributed as dividends.
An S corporation offers pass-through treatment while preserving a corporate legal structure, but federal eligibility limits apply. California also imposes its 1.5% entity-level tax. Owner-employees must consider payroll and compensation rules, and taxable income may pass through even when the company does not distribute enough cash to cover an owner's tax bill.
An LLC often provides flexible management and tax classification. However, California's $800 annual tax and gross-income-based LLC fee can make it expensive for a high-revenue, low-margin operation. An LLC can elect S corporation or C corporation taxation if it meets the applicable requirements, but that election changes tax treatment rather than the underlying state-law entity.
Model several years rather than comparing one rate. Include expected revenue, deductible expenses, owner salaries, distributions, reinvestment, investment plans, and possible exit terms. Legal governance also matters. Corporations use shareholders, directors, and officers, while LLCs rely heavily on their operating agreements. Businesses considering S status can review the broader requirements for an S corporation in California.
Federal Corporate Tax Versus the California Rate
The federal corporate income tax rate is 21% for C corporations. It does not replace California's 8.84% tax. A C corporation subject to both systems calculates its federal and California taxable income under separate rules and may owe tax to both governments.
For example, multiplying $100,000 by 21% produces $21,000, but that result is only a simplified federal illustration when the company has $100,000 of federal taxable income. California's simplified calculation on $100,000 of California net taxable income would be $8,840. The two taxable-income figures may differ because federal and California law do not allow every item, deduction, credit, or adjustment in the same way.
S corporations generally do not pay the 21% federal C corporation tax. Instead, income passes through to shareholders for federal tax purposes. California still charges the S corporation's 1.5% entity-level tax and taxes shareholders under the rules applicable to their pass-through income.
When comparing states, avoid looking only at statutory corporate rates. Some states use gross receipts or margin taxes, while others impose income taxes, franchise charges, or owner-level taxes. For example, reviewing business taxes in Texas shows why a state without a conventional corporate income tax may still impose a significant business-level tax.
Frequently Asked Questions
Are C corporations subject to a state-level gross receipts tax in California?
No, California C corporations are not generally subject to a broad state gross receipts tax. A C corporation's principal California franchise or income tax uses net taxable income. However, particular transactions, industries, and local jurisdictions may create separate obligations, so a company should classify each charge instead of assuming the 8.84% rate covers every state and local tax.
Is it better to have an LLC or corporation in California?
Neither structure is universally better in California. An LLC can offer management and tax flexibility, while a corporation may better support stock issuance, outside investment, and formal governance. The right choice depends on revenue, profit margins, owner compensation, financing plans, liability concerns, and exit strategy, not merely the difference between an $800 annual charge and a percentage tax.
Is corporate tax 21%?
Yes, 21% is the federal C corporation income tax rate, not California's state rate. A corporation operating in California may have federal and state liabilities at the same time. Because each system has its own deductions, adjustments, credits, and filing requirements, adding the two statutory percentages does not necessarily produce the company's effective combined tax rate.
Which U.S. state has the highest corporate tax rate?
New Jersey is commonly identified as having the highest top state corporate income tax rate, but rankings can change as rates and temporary surcharges change. A rate-only ranking also omits franchise taxes, gross receipts taxes, local taxes, deductions, and apportionment rules. Compare the full tax structure before deciding that one state is more or less expensive for a particular company.
Does an inactive California corporation still owe tax?
Yes, an inactive corporation may still owe California's minimum franchise tax if it remains legally active or has not completed the required dissolution or withdrawal process. Stopping sales, closing a bank account, or abandoning operations does not automatically terminate the entity. Check the corporation's status and complete both tax and corporate closure requirements before assuming future obligations have ended.
Can a California LLC elect to be taxed as a corporation?
Yes, an eligible California LLC can elect federal corporate tax treatment and generally follows that classification for California income-tax purposes. It may also pursue S corporation treatment if it qualifies and completes the necessary elections. The choice affects taxation but does not turn the LLC into a corporation under California entity law, so its operating agreement and governance remain relevant.
