1099 Contractor in Arizona with a New Hampshire Client: Where Do You File?
Answer
Arizona only. Nothing about invoicing a New Hampshire client changes where your work is performed, and New Hampshire has no income tax in any event — so the whole obligation is Arizona estimated payments during the year and a Arizona resident return at the end of it.

Questions people actually ask
I live in Arizona and my client is in New Hampshire. Do I have to file a New Hampshire tax 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 Arizona and New Hampshire hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
