1099 Contractor in Wyoming with a Massachusetts Client: Where Do You File?
Answer
One state at most. Wyoming does not tax earned income; Massachusetts does, but only what is sourced to Massachusetts. For a contractor working entirely from Wyoming, that source amount is normally zero regardless of where the invoices are sent.

Two things make this pairing simple. Wyoming levies no personal income tax, so there is no resident return; and Massachusetts taxes nonresidents only on services actually performed inside Massachusetts, which for a fully remote contractor is normally nothing.
Massachusetts publishes no de minimis day count or dollar floor for nonresidents. Any Massachusetts-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 Massachusetts Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in Wyoming and my client is in Massachusetts. Do I have to file a Massachusetts tax return?
One state at most. Wyoming does not tax earned income; Massachusetts does, but only what is sourced to Massachusetts. For a contractor working entirely from Wyoming, that source amount is normally zero regardless of where the invoices are sent.
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 Wyoming and Massachusetts hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
