(II) If the amount of such credit exceeds the limit set forth in subdivision (I) of this division, the excess may be taken as a credit of up to $1 million for any one taxable year against such taxpayer's quarterly or monthly payments under Code Section 48-7-103, provided that such $1 million limit shall be reduced by any amount taken by such taxpayer pursuant to subdivision (c)(2)(B)(ii)(II) of Code Section 48-7-40.2. Each employee for whom an employer receives credit against such employer's quarterly or monthly payment under Code Section 48-7-103 shall receive credit against his or her income tax liability under Code Section 48-7-20 for the corresponding taxable year for the full amount which would be credited against such liability prior to the application of the credit provided for in this paragraph. Credits against quarterly or monthly payments under Code Section 48-7-103 and credits against liability under Code Section 48-7-20 established by this subparagraph shall not constitute income to the employee; provided, however, that credit allowed and used pursuant to subdivision (II) of this division and pursuant to subdivision (c)(2)(B)(ii)(II) of Code Section 48-7-40.2 shall not exceed $10 million in aggregate for all taxpayers for any calendar year. The commissioner shall establish an application process to ensure that the $10 million aggregate maximum and the $1 million per taxpayer maximum are not exceeded. If applications for such credit exceed $10 million for the calendar year, the commissioner shall allow for the credit to be applied to all eligible applicants in prorated amounts among such applicants, not to exceed $10 million for the calendar year.
