1099 Contractor in Nebraska with a Idaho Client: Where Do You File?
Answer
Two possible returns, one certainty. The certainty is Nebraska, which taxes residents on all self-employment income and expects quarterly estimated payments. The possibility is Idaho, which taxes nonresidents on services actually performed inside the state — invoices sent there do not count.

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

Questions people actually ask
I live in Nebraska and my client is in Idaho. Do I have to file a Idaho tax return?
Two possible returns, one certainty. The certainty is Nebraska, which taxes residents on all self-employment income and expects quarterly estimated payments. The possibility is Idaho, which taxes nonresidents on services actually performed inside the state — invoices sent there do not count.
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 Nebraska and Idaho hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
