My client owns 2 Businesses (as a Sole Proprietor in both cases).  He LIVES in New Hampshire, and operates a business in New Hampshire.  He operates a SEPARATE business in Massachusetts.  So he needs to file a Non-Resident MA Tax Return.  The MA Proseries software allows for me to allocate income based on the number of days worked in each state, but there does not seem to be a way to tax ALL of the MA business income to MA, and then tax NONE of the NH income to MA.

Any suggestions?
