tax purposes are a coercive form of self incrimination

they can't chase everyone and they pick the ripe low hanging fruit not the skimpy ones 

 A better phrasing would be "tax collectors call spending selling"

Your phrasing implies they're not lying, which hurts your brain and the brains of your readers in a psychic way imo

This is an overarching problem across the English language (don't know about others)
