1099 Contractor in Massachusetts with a Oregon Client: Where Do You File?
Answer
Massachusetts always, Oregon sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Massachusetts through the year, and file a Oregon nonresident return for any income from work you physically performed in Oregon, claiming the credit back on the Massachusetts return.

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 Oregon is measured in days on the ground rather than in invoices sent.
Oregon publishes no de minimis day count or dollar floor for nonresidents. Any Oregon-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 Oregon Department of Revenue nonresident instructions before filing.

Questions people actually ask
I live in Massachusetts and my client is in Oregon. Do I have to file a Oregon tax return?
Massachusetts always, Oregon sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Massachusetts through the year, and file a Oregon nonresident return for any income from work you physically performed in Oregon, claiming the credit back on the Massachusetts 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 Oregon hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
