1099 Contractor in Colorado with a Minnesota Client: Where Do You File?

Colorado always, Minnesota sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Colorado through the year, and file a Minnesota nonresident return for any income from work you physically performed in Minnesota, claiming the credit back on the Colorado return.

Reciprocity agreements are the first thing contractors ask about and the first thing that does not apply to them. Every agreement in the country is a wage-withholding arrangement, and a 1099 has no withholding to switch off.
Minnesota publishes no de minimis day count or dollar floor for nonresidents. Any Minnesota-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 Minnesota Department of Revenue nonresident instructions before filing.
