According to a report from Syracuse University, the IRS managed to actually audit 7,710 “millionaires” in 2022, down from 40,965 just a decade ago. If you claimed the earned income tax credit (for lower-income taxpayers), the audit rate was 5.5 times the national average. Here is a link to this report, complete with some very interesting charts that show just how absurd the IRS audit rate (and who it subjects to audits) actually is.
