Unfortunately, this doesn’t erase the impact. This applies beyond salaries to all resources used for what 174 considers R&D. Servers, software, the desk chair you sit on to do development —- all have to be amortized under 174.
It also applies to e.g. saas used for software development, which never would be depreciated over time previously. So your paid GitHub account? Amortize it over 5 years.
