1099 Contractor in Minnesota with a Delaware Client: Where Do You File?
Answer
Minnesota always, Delaware sometimes. With no withholding on a 1099 the whole tax is yours to manage: estimate to Minnesota through the year, and file a Delaware nonresident return for any income from work you physically performed in Delaware, claiming the credit back on the Minnesota 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.
Delaware publishes no de minimis day count or dollar floor for nonresidents. Any Delaware-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 Delaware Division of Revenue nonresident instructions before filing.

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 Minnesota and Delaware hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
