"(5) APPLICATION WITH OTHER CREDITS.—The credit allowed by

subsection (a) for any taxable year shall not exceed the excess (if any) of— "(A) the regular tax for the taxable year reduced by the sum of the credits allowable under subpart A and sections 27 and 28, over "(B) the tentative minimum tax for the taxable year." (4) GENERAL BUSINESS CREDIT.—Subsection (c) of section 38 (relating to limitation based on amount of tax), as amended by section 631(a), is amended by redesignating paragraph (3) as paragraph (4), and by striking out paragraphs (1) and (2) and inserting in lieu thereof the following: "(1) IN GENERAL.—The credit allowed under subsection (a) for any taxable year shall not exceed the lesser of— "(A) the allowable portion of the taxpayer's net regular tax liability for the taxable year, or "(B) the excess (if any) of the taxpayer's net regular tax liability for the taxable year over the tentative minimum tax for the taxable year.
