Yeah, last time this topic came up, I seem to recall that it turned out the vast majority of "audits" claimed to be targeted at the lower-classes were automated, mostly intended to catch common "whoopsies", and usually resulted in a pretty chill "yo, we think you owe X for reason Y, send us a check if you agree, or else perform the following steps to dispute" letters, not, like, thugs knocking down someone's door and demanding to comb through all their records from the last seven years.

... while audits for rich folks required heavy human involvement right from the beginning, so of course the numbers are skewed such that it looks like they are targeting the middle and lower classes, if you treat both types of audit as identical.

Plus audits on rich folks who tend to employ tax lawyers and specialists would usually not deliberately commit fraud, but use unintended "loopholes" which would require some sort of tribunal to decide legality (such as a court or something).

These sorts of audits may or may not return any extra revenue.

The highest likelihood of tax fraud are people who commit small fraud that, to them, seem undetectable.
