No, a single member Limited Partnership is an entity organized or operated to make a profit, and, therefore, cannot have a NOW account.
"(1) Any individual may maintain a NOW account regardless of the purposes that the funds will serve. Thus, deposits of an individual used in his or her business including a sole proprietor or an individual doing business under a trade name is eligible to maintain a NOW account in the individual's name or in the ``DBA'' name. However, other entities organized or operated to make a profit such as corporations, partnerships, associations, business trusts, or other organizations may not maintain NOW accounts."
