1099 Contractor in North Dakota with a Oregon Client: Where Do You File?
Answer
North Dakota always, Oregon sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to North Dakota 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 North Dakota 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.

Do reciprocity agreements help a 1099 contractor?
