1099 Contractor in Kentucky with a New Jersey Client: Where Do You File?

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

Answer

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

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

Do reciprocity agreements help a 1099 contractor?
