1099 Contractor in North Dakota with a Mississippi Client: Where Do You File?
Answer
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from North Dakota keeps it North Dakota-source and North Dakota-taxed. Travel to Mississippi to work and that portion becomes Mississippi-source, needing a Mississippi nonresident return.

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.
Mississippi publishes no de minimis day count or dollar floor for nonresidents. Any Mississippi-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 Mississippi Department of Revenue nonresident instructions before filing.
