1099 Contractor in Utah with a Louisiana Client: Where Do You File?

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

Answer

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

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

Questions people actually ask

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

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

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