LLC registration with the state and banking

[Eric Schrader]

I have an LLC with an EIN from good ole Uncle Sam. I am looking to get a business bank account so i can start to separate my personnel and business $.

I live in PA.  Should i get a business bank account in PA?  I would think that would make most sense.  I have some personnel accounts with a credit union in MD. (full disclosure.  I reside in PA, live most of my life in MD and work in DE)  I thought it would be easiest if I open a business account with that credit union because that is where the money is for my investment.  BUT  i need to file some items with the MD Comptrollers office.  

I don't see the need to file MD taxes for my business when i will not be doing any business in that state.  

Am i off base ?  Should i just get an account with Capital One or someone like that and keep everything in PA?

thanks
