If there is no 2210, you do not owe a penalty, but you need to remit whatever tax you owe by today. Just because you owe a balance does not mean there is a penalty.
Maine (ME) automatically grants a 6-month extension to October 15. If you owe them taxes, submit payment by April 15 to avoid penalties. You can either include a check with Form 1040EXT-ME or pay online at their EZ Pay site.
