Nonresidents Working Remotely for California Businesses: How to Take Paul Newman’s “The Sting” Out of Your Taxes

Paul Newman Case residency articleWith the rise of e-commerce, advanced telecommunications, and the new prevalence of remote work, more and more people have the option of living in one state while working for an employer in another state, without ever setting foot there. The possibilities for reducing state income taxes through this scenario haven’t been lost on savvy hi-tech employees and business owners in California. By simply moving across state borders and working for a California business (or even running it) through the internet and other telecommunications, they become nonresidents, potentially free of California’s high income tax rates, while still being able to participate in California’s thriving economy.

Of course, this situation isn’t lost on California’s tax enforcement agencies either. Because of that, remote workers need to be careful and understand the tax rules for nonresidents working for California firms.

California Tax Rules For Remote Employees

Generally if you work in California, whether you’re a resident or not, you have to pay income taxes on the wages you earn for those services. That’s due to the “source rule”: California taxes all income with a source in California regardless of the taxpayer’s residency. And for purposes of taxing employees, the source of income from services is the location where the services are performed. This is true even if you are a nonresident, even if the contract with the employer is made out-of-state, and even if the wages are paid outside of California.

You can imagine how important the source rule is for California’s taxing authority, the Franchise Tax Board, when it comes to highly compensated employees like CEOs, actors and athletes. When LeBron James travels to California to play the Clippers at Staples Center, California gets a cut of his pay for that night in the form of state income taxes. The reason: as an employee of his NBA team, James performed his services in California on that night. It doesn’t matter which team he plays for or where he resides. The wages from that game are taxable California-source income.

But what if the employee is a nonresident who never has to set foot in California to perform his services?  Then the source rule works in the nonresident’s favor, even if the employer is California based. Remember, the source of the services is the location where the employee’s work is actually performed, not the location of the employer. A nonresident programmer who monitors and upgrades satellite dish software for a Los Angeles-based media company, all while sitting comfortably in front of his computer in his Austin, Texas condo, doesn’t earn California-source income and doesn’t have to pay California income taxes.

At the employer end, while California companies have to withhold state payroll taxes for resident employees wherever they perform their services, and for nonresident employees for services in-state, this is not the case for nonresident employees who perform services outside of California. This is true, by the way, even if the

employee is a nonresident corporate director (or a non-principal LLC manager) and is compensated for his management work as wages – as long as he only participates remotely (though don’t confuse this with profit distributions to nonresident owners, which I address in a separate article).

Employees vs Independent Contractors: The “Never Set Foot” Rule

Note, this entire analysis assumes the nonresident is an employee, and not an independent contractor. For nonresident independent contractors, different rules applies. Specifically, even if the independent contractor never sets foot in California, if he is performing services for a California customer, he has an economic nexus with the state and is likely doing business in California for income tax purposes. That determination falls under a totally different set of stringent, complex rules, which typically result in the net revenue from a sale in California being subject to California income taxes. This often comes as a shock to nonresident independent contractors who receive an audit notice from the FTB for services performed entirely outside of California, and who thought the “never set foot” in California defense applies to them. It doesn’t. It only applies to employees. Moreover, the status of the vendor as independent contractor matters not only to nonresident sole proprietors, but any out-of-state business entity with sales to California customers. See “Internet-Based Companies and ‘Doing Business’ in California: Be Careful What Your Website Says About You,” for more details about the economic nexus rules.

The “Duty Days” Issue

Returning to our remote employee, so far so good if he hasn’t set foot in California. But what if a difficult glitch arises requiring the programmer to fly to Los Angeles to fix the system on site? Then everything changes. The source rule kicks in against the employee. In that case, just like LeBron James playing at Staples Center, or Paul Newman (who was a resident of Connecticut) making a movie in Hollywood, California taxes the income from those in-state services. What the FTB does then is to use an allocation formula based on “duty days” – the days the employee is present in California and working – in proportion to total work days.

The reason I mention Newman, by the way, is that he prevailed in a famous case against the FTB for his performance in “The Sting.” Newman was able to show that the duty days formula should be based on what his contract actually required for working in and out of California, rather than the FTB’s own calculation of duty days. Paul L. and Joanne W. Newman v. FTB (1989) 208 Cal. App. 3d 972. That’s why it’s very important to have a written employment contract that clearly states what obligations an employee has to work in California and what constitutes such work. In fact, the union contracts of professional athletes and actors usually meticulously define and limit duty days, because so much potential state income taxes are at stake. Highly compensated managers, executives and key personnel who work remotely may also have significant taxes at stake. So, they too need to make sure duty days and other residency language appears in their employment contracts. And as a practical matter, it’s very rare for any remote worker not to have to make some visits to California to perform work while physically present in the state. The more time spend in state, the more tax is at issue, and the more pressing the need for dealing with duty days in the employment agreement.

Note also that it’s easy for LeBron James to prove how many days he worked in California and how many days he worked outside of California. You just have to look up the NBA schedule. It’s not that easy for our programmer or other nonresident workers who perform services from their living room computers. Therefore, scrupulous record-keeping and detailed employment contracts are a necessity.

The Vesting Stock Option Issue

If vesting stock options are part of the remote worker’s compensation package, the tax implications of duty days increase astronomically. That’s because the number of duty days may determine what portion of the stock vesting is allocated to work in California, and if the options are non-qualified or their characterization as compensation isn’t limited by a section 83(b) election, then they will be taxed as wage income. A share of that compensation will be prorated to California, as a result of the duty days spent here.  Needless to say, if the options are related to a startup that hits the jackpot in an IPO or other sale or merger, the value of the options and hence the income tax potentially due to California may be astronomical. The taxation of stock options is inherently complex. The duty days concept adds an extra layer of complexity. Therefore, any remote worker with stock options needs to have their compensation package carefully analyzed and managed for this vulnerability by tax counsel who understands California-sourcing rules. This applies to other forms of vesting compensation, such as restricted stock units, golden handcuffs, or phantom stock incentive plans.


To summarize, working remotely for a California firm as a nonresident has the potential for significant tax savings, but there are important caveats.

First, the entire favorable tax treatment of working remotely is based on the assumption that the employee is truly a legal nonresident. For employees who move from California to a lower tax state like Nevada or Texas, it’s important they follow residency rules and genuinely change their legal residency. If they don’t make the necessary changes to disentangle themselves from California contacts and manage those they keep (like working for a California company remotely), they may find themselves in an unpleasant residency tax audit.

Second, the favorable tax treatment of remote work depends on employee status. Independent contractors working for California firms fall under totally different rules involving “doing business in California.”

Third, make sure to have a written employment contract that spells out the services to be performed out of state and in state, if any. In this way you are in control of the “duty days” allocation, not the FTB.

Finally, if any work is required on site (and it almost always will be at some point) keep good records of your work both in and out of state. This will allow you to make the most of the “duty days” formula allocation. That allocation is all the more important if the nonresident’s compensation package includes vesting stock options.  If that’s the case, how duty days are defined or limited may make a tremendous difference in California taxes owed.
