You don’t have to file taxes if you make less than $10k…I think that figure rose to $12k in 2020…how can you or the article prove he made more than that each of those 4 years? Always have to keep an ear open to both sides of the discussion!
Still, you're probably leaving money on the table if you don't file with no income, especially this last year with all the stimulus.
About whether McAfee could prove no income, I guess he would've had his day in court to show it.
I would say the burden of proof is on the government.
