1099 Contractor in North Carolina with a Pennsylvania Client: Where Do You File?
Answer
North Carolina taxes all of it; Pennsylvania taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay North Carolina quarterly. A Pennsylvania client alone creates no Pennsylvania filing obligation — performing services inside Pennsylvania does, and North Carolina 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.
Pennsylvania publishes no de minimis day count or dollar floor for nonresidents. Any Pennsylvania-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 Pennsylvania Department of Revenue nonresident instructions before filing.
