Spending it also counts as selling, for tax purposes.
Discussion
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)
