It’s referring to the Pareto principle, “80% of the effects come from 20% of the causes”. To 80⁄20 tax law would be to learn the 20% of tax law that gives you 80% of the benefits of knowing tax law.
I know of Pareto principle, just haven’t figured out that ‘to 80⁄20’ means ‘to learn tax law 20%’. Makes sense in general; the only obvious problem I see here is: how do I know how much of the tax law is 20%? (seriously, at least a rough approximation?)
