New Tax Bracets from the IRS

The brackets are a bit higher this year, with the 10% bracket rising 3.9% while the 35% braket rose 2.3% to $640,000

Taxable income( after deductions and exemptions)
Under $50,000 is 10% or 12%
Between $50001 and $105,000 22%
$105,001-$201,000 24%
$201-256,000 32%
$256-$640 35%
640 and up- 37%

A person who makes $1,000,000 does not pay 37% on that million. They would pay 12% on the first $50,000, 22% on the next $65,000,
24% on the next $96,000, ect, ect.
That is the theoretical. In reality, the more income you have, the more opportunity to invest it in ways that shield future income from these rates. A person who collects a $1,000,000 salary is subject to more taxes than an investor who collects $1,000,000 in capital gains.

The $640K question is how much Federal tax is owed. For a single person with a standard deduction of $16,100, it would be around $192.655, or 30.1%. Throw in your state, and local taxes you're probably looking at a higher number, over 40%. But if you live in a state that doesn't levy state and local taxes, you'll be back at 30.1%.

Topics such as AGI and session reporting are not covered here.

Someone with a million-dollar income is not taking the standard deduction.

Not necessarily since they would be subject to the SALT cap. If they didn't have any deductible interest like mortgage or investment interest, and didn't make any contributions to charity, then they would have nothing else to itemize.
