1099 Contractor in Texas with a Iowa Client: Where Do You File?
Answer
Texas taxes nothing, and Iowa taxes you only if you work there. Living in Texas means no resident return at all. A Iowa client does not create a Iowa filing obligation by itself — physically performing services inside Iowa does, and then only for that portion.

The most common contractor worry — that invoicing an out-of-state client creates a filing obligation there — is usually unfounded. What creates the obligation is physical presence, and Texas residents have no home-state return in any case.
Iowa publishes no de minimis day count or dollar floor for nonresidents. Any Iowa-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 Iowa Department of Revenue nonresident instructions before filing.

- Remote worker: Texas → IowaNo state income tax on your wages
- Moved mid-year: Texas → IowaOne part-year return — the state you moved to

Questions people actually ask
I live in Texas and my client is in Iowa. Do I have to file a Iowa tax return?
Texas taxes nothing, and Iowa taxes you only if you work there. Living in Texas means no resident return at all. A Iowa client does not create a Iowa filing obligation by itself — physically performing services inside Iowa does, and then only for that portion.
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 Texas and Iowa hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
