What are the requirements for dissolving a LLC in Maryland, specially if we haven't done any tax return or submitted Personal property return so far?

We started our LLC in 2010 as a joint partnership to invest in stocks and bonds. Since then we have only made a loss (of close to $1000). Most of our tax documents are missing and hence we couldn't do a tax return; I guess we could request our brokerage firm to send us the documents. But we also haven't done personal property return in maryland ($300) as we weren't sure if we need to do this. Now that we want to dissolve the LLC, do we need to file the tax return and submit the personal property return before we file the application to dissolve the LLC?
