1099 Contractor in North Carolina with a Wisconsin Client: Where Do You File?

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

Answer

North Carolina always, Wisconsin sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to North Carolina through the year, and file a Wisconsin nonresident return for any income from work you physically performed in Wisconsin, claiming the credit back on the North Carolina return.

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 Wisconsin is measured in days on the ground rather than in invoices sent.

Wisconsin publishes a dollar floor for nonresidents rather than a day count. Wisconsin publishes a nonresident gross-income floor: a nonresident with Wisconsin gross income below the published amount is not required to file a Wisconsin return. Reaching it brings the whole Wisconsin-source amount into the return.

Questions people actually ask

I live in North Carolina and my client is in Wisconsin. Do I have to file a Wisconsin tax return?

North Carolina always, Wisconsin sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to North Carolina through the year, and file a Wisconsin nonresident return for any income from work you physically performed in Wisconsin, claiming the credit back on the North Carolina return.

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 North Carolina and Wisconsin hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
