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

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

Answer

Kansas taxes all of it; Ohio taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay Kansas quarterly. A Ohio client alone creates no Ohio filing obligation — performing services inside Ohio does, and Kansas then credits that tax.

The client's location is the wrong thing to track. What matters is where you were sitting when you did the work — which is why a contractor's exposure to Ohio is measured in days on the ground rather than in invoices sent.

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

Kansas taxes all of it; Ohio taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay Kansas quarterly. A Ohio client alone creates no Ohio filing obligation — performing services inside Ohio does, and Kansas then credits that tax.

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 Kansas and Ohio hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.

How current is this?
