1099 Contractor in Oregon with a Massachusetts Client: Where Do You File?
Answer
Oregon taxes all of it; Massachusetts taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay Oregon quarterly. A Massachusetts client alone creates no Massachusetts filing obligation — performing services inside Massachusetts does, and Oregon then credits that tax.

The client's location is the wrong thing to track. What matters is where you were sitting when you did the work — which is why a contractor's exposure to Massachusetts is measured in days on the ground rather than in invoices sent.
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 Oregon and my client is in Massachusetts. Do I have to file a Massachusetts tax return?
Oregon taxes all of it; Massachusetts taxes only what you earn on its soil. Nothing is withheld from a 1099, so you pay Oregon quarterly. A Massachusetts client alone creates no Massachusetts filing obligation — performing services inside Massachusetts does, and Oregon then credits that tax.
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 Oregon and Massachusetts hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
