We just started, so there is almost no income and many expenses currently on the books.
I have an S-Corp and several other corps, but I'm not an accountant.
Definitely hire a qualified accountant, as the various state and federal dates and taxes can be confusing. You can also use a Registered Agent service that offer notifications and managed reports so that you don't miss dates. Companies like MyLLC.com (I am not endorsing this - just an example)
