Part VI, Form 990, states that it requests information about policies not required by the Internal Revenue Code. If these policies are not required, why are you asking about them?
One of the purposes of reporting an organization's activities and policies on Form 990 is to provide the IRS and the public with a more complete picture of the organization, including its operations and governance. Another purpose is to promote tax compliance. Even though governance, management and disclosure policies and procedures generally are not required under the Internal Revenue Code, the IRS considers that such policies and procedures generally improve tax compliance. The absence of appropriate policies and procedures may lead to opportunities for excess benefit transactions, inurement, operation for non-exempt purposes and other activities inconsistent with exempt status.
