1099 Contractor in Missouri with a Florida Client: Where Do You File?
Answer
The client's state is irrelevant here twice over. Florida does not tax personal income, and even if it did, a client's mailing address does not by itself source your income to that state. Missouri taxes the profit as resident income.

Questions people actually ask
I live in Missouri and my client is in Florida. Do I have to file a Florida tax return?
The client's state is irrelevant here twice over. Florida does not tax personal income, and even if it did, a client's mailing address does not by itself source your income to that state. Missouri taxes the profit as resident income.
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 Missouri and Florida hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
