What happens if i never dissolved a Maryland business?

I have started both a LLC, and a Corporation through maryland express business filling.  This was over 3 years ago now. I have not done any business activities with them, no profit, no loss... nothing. I have done no annual reportings to federal or state at all.

 

I wish i never registered them, but there they are. What actions do i need to take to get rid of them? Will the state automatically dissolve them for me with time? Or will i will liable for fees and the costs to dissolve them manually?

 

I have seen articles online stating they will automatically dissolve, but i have also seen posts about getting billed 10 years down the road for all the accrued fees.

 

Some advice would be helpful. Thanks
