BURBANK, Calif. — As California businesses expand operations beyond state lines, understanding multi-state tax requirements has become increasingly critical. In 2026, companies engaging in interstate commerce must consider various legal and operational factors to ensure compliance. Failure to navigate these complexities may lead to substantial financial penalties.
Key Considerations for Multi-State Operations
Multi-state taxation primarily hinges on two legal principles: nexus and apportionment. Nexus refers to the connection between a business and a state that justifies state taxation. Each state has its guidelines determining what constitutes sufficient nexus, which may vary significantly.
Understanding Nexus
Typical factors establishing nexus include having a physical presence, such as a store, office, or employee, or engaging in certain economic activities. For California businesses, nexus can arise even from remote employees working from states where the company lacks a physical location. According to the Supreme Court decision in South Dakota v. Wayfair, Inc. (2018), economic nexus is established if a business meets a specific revenue threshold in a state—often as low as $100,000 in sales per year.
Apportionment of Income
Once nexus is established, businesses must apportion income between states. The apportionment formula typically considers property, payroll, and sales—often referred to as the three-factor formula. For instance, the formula may look like this:
[
\text{Apportionment Factor} = \frac{\text{Sales in State}}{\text{Total Sales}} + \frac{\text{Payroll in State}}{\text{Total Payroll}} + \frac{\text{Property in State}}{\text{Total Property}}
]
Determining how much income is attributed to California versus other states is crucial for tax calculations.
California-Specific Requirements
California imposes its tax filings and payment requirements on businesses with nexus. A Corporation Franchise Tax applies at a minimum of $800 annually, regardless of income. Additionally, the state mandates businesses file Form 100 for C corporations or Form 565 for partnerships. It is vital to monitor deadlines, with California's annual franchise tax due by April 15 for most entities.
Sales and Use Tax Obligations
Businesses engaged in retail must also consider sales and use tax obligations. California enforces sales tax on physical and digital goods and services, requiring registration if a business has nexus in the state. When selling to customers in other states, businesses often face varying sales tax rules, which may include different rates and exemptions.
Exemptions and Specific Rates
Businesses offering specific products may qualify for exemptions. For example, certain food products and manufacturing equipment are exempt from sales tax. Understanding local sales tax rates is crucial; for instance, Burbank’s total sales tax rate can be as high as 10.25%, including state and local taxes.
Compliance Tips for Multi-State Taxation
- Conduct a Nexus Analysis: Regularly review business activities in each state to determine where nexus exists, especially with remote employees.
- Consult State-Specific Guides: Every state has its tax regulations. California’s Franchise Tax Board offers resources on various filing requirements.
- Implement Accounting Software: Invest in accounting tools capable of managing multi-state taxation, including nexus tracking and apportionment calculations.

With the combination of nexus determinations, income apportionment, and the array of state-specific requirements, informed awareness and preparation stand as essential practices.

Companies can no longer afford to overlook these operational nuances, as penalties can quickly accumulate.
