Do I need to file a CA state return for misc income received from a clinical drug trial

[MoB13]

I don't live in CA but participated in a clinical drug trial for a medical facility in the state last year. At the end of the trial I received $1500 for participation. Do I need to file a CA return for this income. I have no other connection to CA or income earned there.

@MoB13 The IRS requires research institutions to report compensation to clinical trial participants if the amount is $600 or more a year.

CA requirements of non-residents below come from: https://www.ftb.ca.gov/file/personal/residency-status/part-year-and-nonresident.html  Do note it depends completely of total gross worldwide income if you need to file in CA.  If $1,500 is all your income worldwide then based on charts no, but if your income exceeds below then yes.

CA FTB:  Do I need to file?

As a nonresident, you pay tax on your taxable income from California sources.

Sourced income includes, but is not limited to:

• Services performed in California
• Rent from real property located in California
• The sale or transfer of real California property
• Income from a California business, trade or profession
