In fiscal year 2023, total individual income tax receipts reached $2.177 trillion, while IRS collected $4.9 trillion in total taxes with income tax the clear driver. At the same time, the millionaires audit rate was just 2.4% in FY2022, and the IRS estimated a $688 billion annual tax gap for 2017 to 2019.
