The "inactive" tag means the used hasn't made any main space edit (edit on articles) in 30 days. It is placed and removed automatically.

Anyways, editing an article just to lose the tag while not planning to edit in the future is something againt a logic of the tags. Such a user IS really inacive, so there is no reason to do a pointless edit to remove the "inactive" tag from the inactive user.
