1099 Contractor in New York with a Kansas Client: Where Do You File?
Answer
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from New York keeps it New York-source and New York-taxed. Travel to Kansas to work and that portion becomes Kansas-source, needing a Kansas nonresident return.

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.
Kansas publishes no de minimis day count or dollar floor for nonresidents. Any Kansas-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 Kansas Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in New York and my client is in Kansas. Do I have to file a Kansas tax return?
The client's location does not decide this. Self-employment income from personal services is sourced to where the work happens, so working from New York keeps it New York-source and New York-taxed. Travel to Kansas to work and that portion becomes Kansas-source, needing a Kansas nonresident 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 Kansas hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
