I was quite worried about this so did some digging myself. The wording MD Comptroller supplies is ambiguous at best, but its FAQs supplied with the document dated May 2020 make things clear -- working outside of MD, even for a MD entity, is NOT taxed by MD.

05-04-20 THIS ALERT SUPERSEDES THE PREVIOUS ALERT ISSUED 5-01 EMPLOYER WITHHOLDING REQUIREMENTS FOR TELEWORKING EMPLOYEES DURING THE COVID-19 EMERGENCY On March 5, 2020, Governor Lawrence J. Hogan, Jr. proclaimed a state of emergency and a catastrophic health emergency related to COVID-19. The following tax alert addresses withholding questions received by the Office of the Comptroller of Maryland due to the unprecedented situation caused by the COVID-19 pandemic. Employer Withholding Requirements Maryland employer withholding requirements are not affected by the current shift from working on the employer’s premises to teleworking because taxability is determined by the employee’s physical presence. Generally, Maryland imposes income tax, and therefore a withholding requirement on employers, for employees domiciled in Maryland, statutory residents of Maryland1 , and non-residents receiving Maryland-sourced income. Income is deemed Maryland- sourced income when the income is compensation for services performed in Maryland. Residents of Virginia, Washington D.C., West Virginia, and Pennsylvania who earn wages, salaries, tips, and commission income for services performed in Maryland are exempt from Maryland state income tax, and therefore, withholding, because Maryland has a reciprocal agreement with these states. Unlike the aforementioned states, Delaware has not entered into a reciprocal agreement with the state of Maryland. Compensation paid to a Maryland nonresident who is teleworking in Maryland is Maryland-sourced income, and therefore, subject to withholding. The Comptroller’s Office does not intend to change or alter the facts and circumstances it has consistently used to determine nexus or income sourcing. As has always been the case, the Office reviews and considers the specific facts and circumstances of each taxpayer in order to make a fair determination. In doing so going forward, the Office understands that many businesses have been required or otherwise found it necessary during the COVID-19 health emergency to temporarily alter their workplace model and deployment of their employees. The Office further understands that this was done in order to comply with the various gubernatorial executive orders and health department and CDC recommendations on social distancing. Consequently, the Office will recognize the temporary nature of a business’ interim workplace model and employee deployment in light of and during the current health emergency and will 1 Active duty military and the spouses of active duty military are not deemed statutory residents when their presence in Maryland is solely the result of military orders. not use these temporary measures to impose business nexus, to alter the sourcing of business income, or to impose additional withholding requirements on the employer.
