1099 Contractor in Connecticut with a Texas Client: Where Do You File?
Answer
Connecticut only. Nothing about invoicing a Texas client changes where your work is performed, and Texas has no income tax in any event — so the whole obligation is Connecticut estimated payments during the year and a Connecticut resident return at the end of it.

Questions people actually ask
I live in Connecticut and my client is in Texas. Do I have to file a Texas tax return?
Connecticut only. Nothing about invoicing a Texas client changes where your work is performed, and Texas has no income tax in any event — so the whole obligation is Connecticut estimated payments during the year and a Connecticut resident return at the end of it.
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 Connecticut and Texas hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
