1099 Contractor in New Hampshire with a Missouri Client: Where Do You File?
Answer
Missouri only, and only for on-site work. Nothing is withheld from a 1099, and New Hampshire levies no income tax, so the single question is whether any of the services were performed in Missouri. If none were, no Missouri nonresident return is required.

The most common contractor worry — that invoicing an out-of-state client creates a filing obligation there — is usually unfounded. What creates the obligation is physical presence, and New Hampshire residents have no home-state return in any case.
Missouri publishes no de minimis day count or dollar floor for nonresidents. Any Missouri-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 Missouri Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in New Hampshire and my client is in Missouri. Do I have to file a Missouri tax return?
Missouri only, and only for on-site work. Nothing is withheld from a 1099, and New Hampshire levies no income tax, so the single question is whether any of the services were performed in Missouri. If none were, no Missouri nonresident return is required.
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 Hampshire and Missouri hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
