1099 Contractor in New Hampshire with a Iowa Client: Where Do You File?
Answer
The client's address is not the test. New Hampshire has no personal income tax, so nothing is owed at home; Iowa taxes nonresidents on income from services performed within Iowa, so if you never travel there to work, there is nothing to file. Days on site change that.

Two things make this pairing simple. New Hampshire levies no personal income tax, so there is no resident return; and Iowa taxes nonresidents only on services actually performed inside Iowa, which for a fully remote contractor is normally nothing.
Iowa publishes no de minimis day count or dollar floor for nonresidents. Any Iowa-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 Iowa Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in New Hampshire and my client is in Iowa. Do I have to file a Iowa tax return?
The client's address is not the test. New Hampshire has no personal income tax, so nothing is owed at home; Iowa taxes nonresidents on income from services performed within Iowa, so if you never travel there to work, there is nothing to file. Days on site change that.
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 Iowa hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
