1099 Contractor in New Mexico with a Maine Client: Where Do You File?
Answer
Two possible returns, one certainty. The certainty is New Mexico, which taxes residents on all self-employment income and expects quarterly estimated payments. The possibility is Maine, which taxes nonresidents on services actually performed inside the state — invoices sent there do not count.

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 Maine is measured in days on the ground rather than in invoices sent.
Maine publishes a genuine de minimis for nonresidents — roughly 12 days of work in the state, alongside a dollar floor — below which the income is not taxed there. Maine publishes a genuine de minimis: a nonresident who performs personal services in Maine on 12 or fewer days AND earns under the published dollar floor from Maine sources owes no Maine tax on those wages. Exceeding either test brings the whole amount into Maine.

Questions people actually ask
I live in New Mexico and my client is in Maine. Do I have to file a Maine tax return?
Two possible returns, one certainty. The certainty is New Mexico, which taxes residents on all self-employment income and expects quarterly estimated payments. The possibility is Maine, which taxes nonresidents on services actually performed inside the state — invoices sent there do not count.
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 Maine hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
