You who have not seen it may be interested to read a series of articles in the Washington Post called "Homes for the Taking"
http://www.washingtonpost.com/sf/investigative/collection/homes-for-the-taking/ about a group stealing homes from DC's poor, sick, and elderly over sometimes very small unpaid property tax. I thought this expose served to stop this practice. But now I have also received a "notice of delinquent unincorporated business franchise tax" from MuniServices and am concerned it's the same sleazy group with a different focus. I recommend anyone receiving notices from MuniServices to contact your tax office directly, not MuniServices, for help in resolving the issue. In DC, I contact the chief financial officer's office. They confimed I have no liability and said they would get MuniServices to send me a "letter of no balance". That was in May 2014 and now it's July. I haven't received any letter, so I have just contacted constituent services in my Council Member's office. Because of the very aggressive and unethical behavior towards DC homeowners over property taxes, it seems wise not to ignore MuniServices over tax notices as they might aggressively try to attach your assets. I don't know who else to complain to about this. Does anyone have any ideas?
