1099 Contractor in New Mexico with a Oklahoma 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 New Mexico keeps it New Mexico-source and New Mexico-taxed. Travel to Oklahoma to work and that portion becomes Oklahoma-source, needing a Oklahoma nonresident 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 Oklahoma is measured in days on the ground rather than in invoices sent.
Oklahoma publishes no de minimis day count or dollar floor for nonresidents. Any Oklahoma-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 Oklahoma Tax Commission nonresident instructions before filing.

Questions people actually ask
I live in New Mexico and my client is in Oklahoma. Do I have to file a Oklahoma tax return?
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from New Mexico keeps it New Mexico-source and New Mexico-taxed. Travel to Oklahoma to work and that portion becomes Oklahoma-source, needing a Oklahoma nonresident return.
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 New Mexico and Oklahoma hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
