The IRS doesn't even have the manpower to audit all of the wealthy people in the USA. I'm not worth their time. Real tyranny will happen when they finally acquisition an AI system that can audit billions of financial transactions every year. But even then they'll need the lawyers to prosecute cases against people. For now the best thing for most people is to keep your tax fillings as simple as you possibly can. Things like doing itemized deductions raise your audit risk. Take the standard deduction even if you end up paying a little more that way. Keep it as simple as possible and you'll fly under their radar.
