1099 Contractor in North Carolina with a Maryland Client: Where Do You File?
Answer
Pay North Carolina by instalments, and watch your Maryland days. Reciprocity agreements do not help here: every one of them covers wage withholding, and a 1099 has no withholding to switch off. North Carolina taxes the full profit, Maryland taxes the on-site share, and the North Carolina credit reconciles them.

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.
Maryland publishes no de minimis day count or dollar floor for nonresidents. Any Maryland-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 Comptroller of Maryland nonresident instructions before filing.

Do reciprocity agreements help a 1099 contractor?
