They do have intelligence, but that intelligence is deliberately underfunded to prevent this very situation. It’s impossible to navigate the mountains of paperwork and legal loopholes the ultra-wealthy use with so few hands. That’s why poorer filers get audited more often: less leg work, easier wins, at the expense of real revenue and justice against tax evaders.
As someone who has spent their life translating for family this isn’t surprising. Nor is it any easier when they bring me poorly translated documents and hope I decipher machine diarrhea. The tech is still years behind being real world ready, especially with anything above 6th grade grammar and nuanced word choice that depends on context and sometimes dialect. But free is free so 🤷
