1099 Contractor in New Jersey with a West Virginia Client: Where Do You File?
Answer
Pay New Jersey by instalments, and watch your West Virginia days. Reciprocity agreements do not help here: every one of them covers wage withholding, and a 1099 has no withholding to switch off. New Jersey taxes the full profit, West Virginia taxes the on-site share, and the New Jersey credit reconciles them.

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 West Virginia is measured in days on the ground rather than in invoices sent.
West Virginia publishes no de minimis day count or dollar floor for nonresidents. Any West Virginia-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 West Virginia Tax Division nonresident instructions before filing.

Do reciprocity agreements help a 1099 contractor?
