> It's also, generally, a complexity problem.

I don't think so in 2023. I worked several years in a tax agency and it was mainly a problem of "motivation". I have a friend who pursued "data warehouse" for 30 years there... nowadays you can crunch all the information and find patterns . I would even suggest that tax agencies should anonymize data and create data bounties to help them. In the same way DARPA creates cyberchallenges [1].

How much of internal accounting state leaks into tax filings?

I assume when you're looking at forensic tax accounting, you're identifying present-year vs previous-year discrepancies?

Or is there enough required in filings to generate something like a complete shadow accounting for a company?

There are relationships between agencies and corporations to link information. It is not only your filings what is at stake.

I think it'd be impossible to anonymize data in such a way that it's still useful but not easily identifiable with public or partial private information.
