It appears the an IT-1040 is the Ohio income tax form. Here is the info on who needs to file from the Ohio revenue department. It is quite complicated (more so than most states). It appears that most people with any almost any OH income (residents or business or property in OH) will need to file an IT-1040, unless they look closely at the exceptions.
