1099 Contractor in Massachusetts with a Florida Client: Where Do You File?
Answer
Only Massachusetts taxes you, and nobody withholds. Florida levies no personal income tax, so a Florida client creates no Florida obligation whatever. You make quarterly estimated payments to Massachusetts on the profit and report it on a Massachusetts resident return.

Questions people actually ask
I live in Massachusetts and my client is in Florida. Do I have to file a Florida tax return?
Only Massachusetts taxes you, and nobody withholds. Florida levies no personal income tax, so a Florida client creates no Florida obligation whatever. You make quarterly estimated payments to Massachusetts on the profit and report it on a Massachusetts resident 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 Massachusetts and Florida hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
