Question about NH return

Hello, my New Hampshire return instructions to mail my return says "You don't need to file a New Hampshire BT-Summary return. The data you entered results in no refund and no tax due." and "You don't need to file a New Hampshire DP-10 return. The data you entered results in no refund and no tax due."  Does this mean I do not have to send anything in because this is all the document says.  Thanks!
