1099 Contractor in Alabama with a Kentucky Client: Where Do You File?

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

Answer

Pay Alabama by instalments, and watch your Kentucky days. Reciprocity agreements do not help here: every one of them covers wage withholding, and a 1099 has no withholding to switch off. Alabama taxes the full profit, Kentucky taxes the on-site share, and the Alabama 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.

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

Questions people actually ask

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