1099 Contractor in North Dakota with a New Mexico Client: Where Do You File?
Answer
North Dakota taxes all of it; New Mexico taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay North Dakota quarterly. A New Mexico client alone creates no New Mexico filing obligation — performing services inside New Mexico does, and North Dakota 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 New Mexico is measured in days on the ground rather than in invoices sent.
New Mexico publishes no de minimis day count or dollar floor for nonresidents. Any New Mexico-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 New Mexico Taxation and Revenue Department nonresident instructions before filing.

Do reciprocity agreements help a 1099 contractor?
