With the rise of the internet, cloud and smart phone economy, more and more people have the option of living in one state while working in another – remotely. 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, 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 taxing authorities either. Because of that “remote workers” need to be careful and understand the tax rules for nonresidents working for California firms.
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. And for tax purposes, 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.
