How does Louisiana handle the adjustment made under IRC Section 280C?

Internal Revenue Code Section 280C requires a taxpayer who elects to claim certain credits that are based on an expense to reduce the federal deduction for the expense by the dollar amount of the credit claimed. Under R.S. 47:293(9)(ix) Louisiana allows the deduction of any expenses disallowed by IRC Section 280C in calculating Louisiana taxable income for an individual. Therefore the amount of the expense disallowed under IRC Section 280C can be deducted in calculating taxable income for Louisiana. For a resident taxpayer, this adjustment would be done on Schedule E, line 5B of Form IT-540. For a nonresident or part-year resident taxpayer, this adjustment would be done on the Nonresident and Part-year Resident Worksheet of Form IT-540B.
