1099 Contractor in Delaware with a Nebraska Client: Where Do You File?
Answer
Pay Delaware by instalments, and watch your Nebraska days. Reciprocity agreements do not help here: every one of them covers wage withholding, and a 1099 has no withholding to switch off. Delaware taxes the full profit, Nebraska taxes the on-site share, and the Delaware 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 Nebraska is measured in days on the ground rather than in invoices sent.
Nebraska publishes no de minimis day count or dollar floor for nonresidents. Any Nebraska-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 Nebraska Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in Delaware and my client is in Nebraska. Do I have to file a Nebraska tax return?
Pay Delaware by instalments, and watch your Nebraska days. Reciprocity agreements do not help here: every one of them covers wage withholding, and a 1099 has no withholding to switch off. Delaware taxes the full profit, Nebraska taxes the on-site share, and the Delaware credit reconciles them.
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 Delaware and Nebraska hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
