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

The client's location is the wrong thing to track. What matters is where you were sitting when you did the work — which is why a contractor's exposure to Georgia is measured in days on the ground rather than in invoices sent.
Georgia publishes no de minimis day count or dollar floor for nonresidents. Any Georgia-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 Georgia Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in Montana and my client is in Georgia. Do I have to file a Georgia tax return?
Montana taxes all of it; Georgia taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay Montana quarterly. A Georgia client alone creates no Georgia filing obligation — performing services inside Georgia does, and Montana then credits that tax.
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 Montana and Georgia hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
