Personally I think this is one of the killer applications for LLM. In some countries you can even have double tax deduction instead of only normal tax deduction for R&D activities, if your company fulfills the government requirements and following the correct procedures. But the main problem is that the info is oblivious to most of the companies and majority are ignorant of the tax discount facility available to them with respect to R&D [1].
