According as the historical series, since the implementation of the law, the number of companies using the benefits has grown exponentially, but the number of beneficiaries is still very low. This article presents the results of the study with a group of 100 companies. The objective was to verify the innovation management practices used by these companies, as well as the main obstacles encountered by them to make use of tax incentives of the Good Law. The results showed that the biggest obstacle for use of the Good Law is the profile of the innovation projects.
