1099 Contractor in Iowa with a Hawaii Client: Where Do You File?
Answer
Iowa taxes all of it; Hawaii taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay Iowa quarterly. A Hawaii client alone creates no Hawaii filing obligation — performing services inside Hawaii does, and Iowa then credits that tax.

Reciprocity agreements are the first thing contractors ask about and the first thing that does not apply to them. Every agreement in the country is a wage-withholding arrangement, and a 1099 has no withholding to switch off.
Hawaii publishes no de minimis day count or dollar floor for nonresidents. Any Hawaii-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 Hawaii Department of Taxation nonresident instructions before filing.

Do reciprocity agreements help a 1099 contractor?
