A QIP is a partnership or other entity classified as a subchapter K entity, or a business trust as defined in §40-18-1, Code of Alabama 1975, that for a tax period meets the gross income and asset requirements for a Qualified Investment Partnership as required by §40-18-24.2; and, for which an authorized officer, partner, member or manager of the entity has certified for the tax period that the entity meets the gross income and asset requirements. Proper certification of a QIP requires the completion of Alabama Schedule QIP-C, Qualified Investment Partnership Certification, which must be filed by the due date of the Alabama partnership income tax return for the entity.
