1099 Contractor in New Mexico with a Massachusetts Client: Where Do You File?
Answer
New Mexico always, Massachusetts sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to New Mexico through the year, and file a Massachusetts nonresident return for any income from work you physically performed in Massachusetts, claiming the credit back on the New Mexico return.

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 Massachusetts is measured in days on the ground rather than in invoices sent.
Massachusetts publishes no de minimis day count or dollar floor for nonresidents. Any Massachusetts-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 Massachusetts Department of Revenue nonresident instructions before filing.

Do reciprocity agreements help a 1099 contractor?
