1099 Contractor in Iowa with a Ohio Client: Where Do You File?

Home state, plus the client state if you work thereNo withholding — 1099

Answer

Iowa always, Ohio sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Iowa through the year, and file a Ohio nonresident return for any income from work you physically performed in Ohio, claiming the credit back on the Iowa return.

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.

Ohio publishes no de minimis day count or dollar floor for nonresidents. Any Ohio-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 Ohio Department of Taxation nonresident instructions before filing.

Questions people actually ask

I live in Iowa and my client is in Ohio. Do I have to file a Ohio tax return?

Iowa always, Ohio sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Iowa through the year, and file a Ohio nonresident return for any income from work you physically performed in Ohio, claiming the credit back on the Iowa 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 Iowa and Ohio hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
