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

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.
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 New York and my client is in Wisconsin. Do I have to file a Wisconsin tax 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 New York and Wisconsin hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
