Update on Application Processing Time:

LED processes applications on a first in, first out basis. There are three categories of R&D applications: (1) companies with 50+ employees (“6765”); (2) companies receiving federal SBIR grants (“SBIR”); and (3) companies with less than 50 employees (“LQRE”). Currently, 6765 and SBIR applications are processed within 90 days, unless additional information is needed or the application is selected for detailed review (statutorily required for at least 10% of applications). The LQRE application process currently requires six to eight months due to the detailed review required and a dramatic increase in the volume of applications, many for companies whose activities are not eligible for R&D credits. For example, within recent years one consulting firm has submitted applications of which over 90% have been denied credits due to ineligibility. Most of the LQRE applications submitted by other firms have been eligible for the program. To minimize the time needed for processing, all applicants are advised to make sure all requested information is provided in a timely manner, and if they choose to retain a consultant, to choose carefully.

This program is administered by Louisiana Economic Development.
