1099 Contractor in Kansas with a Indiana Client: Where Do You File?

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

Answer

Two possible returns, one certainty. The certainty is Kansas, which taxes residents on all self-employment income and expects quarterly estimated payments. The possibility is Indiana, which taxes nonresidents on services actually performed inside the state — invoices sent there do not count.

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.

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

Questions people actually ask

I live in Kansas and my client is in Indiana. Do I have to file a Indiana tax return?

Two possible returns, one certainty. The certainty is Kansas, which taxes residents on all self-employment income and expects quarterly estimated payments. The possibility is Indiana, 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 Kansas and Indiana hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
