The transferable R&D tax credits issues to SBIR applicants are entered into the Louisiana Department of Revenue Tax Registry. Upon the certification of the tax credits, Form R-6135 Credit Utilization Form will be issued by LDR. The applicant must notify LDR within 10 business days of the transfer. All transferable credits must be transferred by the original due date of the return. Please refer to the Revenue Information Bulletin 14-005 that provides more information on transferable tax credits.
