California Still Wants Your Money: How the FTB Taxes Nevada Residents on California-Client Income
California Still Wants Your Money: How the FTB Taxes Nevada Residents on California-Client Income
About This Series
This is the final installment of our 2026 Cross-State Wealth and Business Planning Series, a six-part sequence exploring how California residents can lawfully reduce their state tax burden by relocating to Nevada—or another low-tax state—or by using Nevada-based trust, entity, and corporate structures. Earlier installments covered establishing residency (Part 1), trust planning for those who stay (Part 2), QSBS and corporate strategies (Parts 3 and 4), and post-relocation compliance (Part 5). This concluding article addresses a problem that surprises many: how the FTB reaches across state lines to tax Nevada residents who serve California clients.
A professional we know — a consultant based in Reno, licensed and operating entirely from Nevada — received a notice from the California Franchise Tax Board claiming he owed California income taxes. His offense? He had performed services for a California-based company under a 1099 arrangement. He never entered California to do the work. While he left California over a decade prior, he maintained no California office, no California employees, and no California assets. Every deliverable was produced from his Nevada office and transmitted to clients electronically.
The FTB’s theory was simple: because the client who received the benefit of his services was located in California, the income was California-source income — and California wanted its 13.3%.
If you’ve made the move to Nevada (Part 1 of this series), set up your entities (Parts 3 and 4), and built your post-relocation compliance practices (Part 5), you might assume you’re done. But the FTB has theories that reach across the state line even when you never cross it yourself. This article covers the three most important ones.
Theory 1: Market-Based Sourcing — Where the “Benefit” Is Received
Since 2013, California has sourced service income based on where the customer receives the benefit of the service — not where the service provider performs the work. This is codified in Revenue and Taxation Code Section 25136 and implemented through Regulation Section 25136-2, which was most recently amended with changes effective for tax years beginning on or after January 1, 2026.
The rule works like this: if you are a Nevada-based independent contractor and your client is a California company, the FTB will treat the income from that engagement as California-source income to the extent the client received the “benefit” of your services in California. If the
evidence of where the benefit was received is not readily available, the FTB defaults to the customer’s billing address.
The practical consequence is stark. A consultant, designer, software developer, or any service professional living and working entirely in Nevada can owe California taxes on income earned from California clients — even though they never set foot in the state. The sourcing follows the customer, not the provider.
How the FTB Determines “Benefit Received”
Regulation 25136-2 provides a hierarchy. The FTB first looks at where the customer directly or indirectly received value from the service. For services delivered to a specific location (like construction or on-site consulting), the answer is obvious. For professional services delivered remotely — legal advice, consulting reports, software development — the analysis becomes murkier.
If the benefit location cannot be reasonably determined, the regulation defaults to the customer’s billing address. In practice, this default swallows most independent contractor situations: the client is in California, the 1099 lists a California address, and the FTB treats the income as California-source.
This is not a fringe theory. The FTB applies it routinely, and the burden falls on the nonresident to demonstrate that the benefit was received elsewhere.
Theory 2: “Doing Business” Nexus Under R&TC Section 23101
California defines “doing business” broadly. Under Revenue and Taxation Code Section 23101, a taxpayer is doing business in California if it is “actively engaging in any transaction for the purpose of financial or pecuniary gain or profit.” The statute also provides bright-line thresholds that are adjusted annually for inflation: the base amounts are $500,000 for California sales, $50,000 for California property, and $50,000 for California payroll, but the inflation-adjusted thresholds for 2025 were approximately $757,070 for sales and $75,707 for property and payroll (the 2026 figures will be slightly higher—check the FTB’s current-year published amounts). If a taxpayer exceeds the applicable threshold, it is deemed to be doing business in the state.
For entity-level taxation, this matters independently of market-based sourcing. If your Nevada LLC or corporation has “sales” in California—and under market-based sourcing, income from California clients counts as California sales—you may exceed the applicable inflation-adjusted threshold and be deemed to be “doing business” in California. That triggers California’s $800 minimum franchise tax and potentially subjects the entity’s apportioned income to California taxation.
The FTB interprets these thresholds aggressively. In a 2019 ruling involving a Delaware LLC, the FTB found that the “doing business” thresholds were not a safe harbor — a taxpayer could be found to be doing business in California even below the threshold amounts if there was sufficient “active engagement” in the state. The thresholds create a presumption, but the FTB reserves the right to assert nexus on other grounds.
Theory 3: Income Apportionment for Multistate Businesses
If you operate a business that has customers in multiple states — including California — the FTB may require you to apportion your business income to California based on the percentage of your sales attributable to California customers.
California uses a single-factor sales apportionment formula for most businesses. Under R&TC Section 25128.7, the apportionment percentage is determined entirely by the ratio of California sales to total sales. Because service sales are sourced using market-based sourcing (where the benefit is received), any service income from California clients increases the numerator of your apportionment fraction — and increases the share of your total business income that California claims the right to tax.
For a Nevada-based professional with a significant California client base, the math can be punishing. If 40% of your clients are in California, the FTB’s position is that 40% of your entire business income is California-source — regardless of where you performed the work. The income is apportioned based on where the customers are, not where you sit.
The Compounding Effect: When All Three Theories Stack
These theories do not exist in isolation. The FTB can — and does — apply them together. Here’s how the scenario plays out for a Nevada-based professional serving California clients:
Step 1: Market-based sourcing treats income from California clients as California-source income, even though all work was performed in Nevada.
Step 2: If California-source sales exceed the inflation-adjusted threshold (approximately $757,070 for 2025; check the FTB’s published figure for the current year), the FTB deems the Nevada entity to be “doing business” in California under R&TC 23101, triggering the $800 minimum franchise tax and entity-level filing requirements.
Step 3: The entity must now apportion its total business income to California using the single-factor sales formula, with California sales in the numerator. The result: a significant percentage of total business income is taxed by California at up to 13.3% for individuals or 8.84% for C corporations.
The professional who thought they were operating entirely from Nevada is now filing California returns, paying California taxes, and potentially facing penalties for prior years when they did not file — all without ever physically entering the state.
Defensive Strategies for Nevada Residents with California Clients
These FTB theories are aggressive, but they are not absolute. Here are the strategies that matter most.
Restructure your client relationships to document where the benefit is received. If your services benefit a client’s operations outside California — for example, the deliverable is used by the client’s Nevada or national operations rather than its California office — document that. Engagement letters should specify the location where the service benefit is received. This creates a record that pushes back against the FTB’s default to the billing address.
Monitor the doing-business thresholds. Track your California-source revenue (as the FTB would calculate it under market-based sourcing) against the inflation-adjusted threshold. If you’re approaching the line, consider whether restructuring your client mix, pricing, or entity
structure can keep you below it. Crossing the threshold triggers filing obligations and the $800 minimum tax.
Use a Nevada entity with substance. Operating through a properly administered Nevada LLC or corporation — with Nevada-based management, bank accounts, and operational records — does not eliminate the sourcing rules, but it reinforces the narrative that your business is a Nevada operation. Entity-level filings, if required, are based on apportionment, and the lower your California sales fraction, the less income California can claim.
Apportion aggressively and accurately. If you are required to file in California, the apportionment calculation is your primary defense on the amount of tax owed. Ensure your sales factor accurately reflects only the income properly sourced to California under the market-based rules. Overstating your California fraction costs you money. Work with a CPA experienced in multistate apportionment.
Negotiate from a position of documentation. If the FTB asserts a deficiency, the quality of your records determines the outcome. Engagement letters specifying where work is performed and where benefits are delivered, contemporaneous time records, and clear invoicing that distinguishes California-client work from other work all strengthen your position. The FTB is more likely to pursue — and sustain — assessments against taxpayers with poor documentation.
Consider the interplay with trust and entity planning. The strategies discussed in Parts 2 through 4 of this series — complete gift non-grantor trusts, QSBS planning, and Nevada C corporation subsidiaries — can interact with sourcing rules. Income earned inside a Nevada trust or a Nevada C corporation subsidiary may be subject to different sourcing analysis than income earned by an individual. The details are complex, but the principle is that entity and trust structuring can shift the sourcing analysis in your favor when combined with genuine Nevada substance.
Frequently Asked Questions
I live and work entirely in Nevada. Can California still tax my income?
Yes, if you have California clients. Under California’s market-based sourcing rules (R&TC Section 25136), service income is sourced to where the customer receives the benefit of the service. If your customer is in California, the income may be treated as California-source income regardless of where you performed the work.
Does it matter that I’m an independent contractor, not an employee?
Yes, but not in the way most people expect. Employee wages are generally sourced to where the work is performed (the “duty days” method). Independent contractor income, by contrast, is sourced under market-based rules — to where the client receives the benefit. This means independent contractors who never enter California may have more California-source income than employees who occasionally work there.
What is the $500,000 doing-business threshold?
Under R&TC Section 23101(b), a taxpayer is deemed to be “doing business” in California if its California sales exceed the inflation-adjusted threshold (the base statutory amount is $500,000, but the 2025 adjusted figure was approximately $757,070). For service businesses, California
“sales” are calculated using market-based sourcing. Exceeding the threshold triggers California entity-level filing requirements, the $800 minimum franchise tax, and potential apportionment of business income to California.
Can I avoid California taxes by invoicing through a Nevada LLC?
Using a Nevada LLC does not, by itself, change the sourcing of income. If the LLC performs services for California clients, the income from those clients is still potentially California-source under market-based rules. However, a genuinely administered Nevada entity can affect the apportionment analysis and, combined with proper documentation, may reduce the California tax exposure.
What should my engagement letters say?
Engagement letters should specify where the services will be performed (Nevada), where the deliverables will be used, and where the client will receive the benefit of the services. If the benefit is received outside California — for example, the work supports the client’s national operations or a non-California division — document that clearly. This creates a contemporaneous record that can rebut the FTB’s default to the billing address.
