1099 Contractor in Louisiana with a California Client: Where Do You File?
Answer
Louisiana taxes all of it; California taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay Louisiana quarterly. A California client alone creates no California filing obligation — performing services inside California does, and Louisiana then credits that tax.

Reciprocity agreements are the first thing contractors ask about and the first thing that does not apply to them. Every agreement in the country is a wage-withholding arrangement, and a 1099 has no withholding to switch off.
California publishes no de minimis day count or dollar floor for nonresidents. Any California-source wage income above the state's general filing threshold requires a nonresident return, and that threshold is reset each year — check the current figure on the California Franchise Tax Board nonresident instructions before filing.

Do reciprocity agreements help a 1099 contractor?
No. Every state reciprocity agreement in the country is an arrangement about wage withholding between two revenue departments, and a 1099 has no withholding to switch off. Whether Louisiana and California hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
