To qualify for this credit the taxpayer must obtain a certificate from the South Carolina Department of Commerce certifying that the entity into which the funds are invested is a community development corporation or a community development financial institution within the meaning of Section 34-43-20(2) or (3) and certifying that the credit taken or available to that taxpayer will not exceed the aggregate five million dollar limitation of all those credits as provided in subsection (B) when added to the credits previously taken or available to other taxpayers making similar investments. A taxpayer who invested in good faith in a certified corporation or institution may claim the credit provided in this section, notwithstanding the fact that the certification is later revoked or not renewed by the department.
(H) To receive the credit provided by this section, a taxpayer shall:
