Which Form should be used to file an Idaho State Corporation Tax Return
All Idaho Corporation must be filed on Form 41, Idaho Corporation Income Tax Return.
Remember, a complete copy of the federal income tax return must be attached to the Idaho income tax return. "A Failure to attach a complete copy of the federal return may cause the return to be delinquent."
