The Buffett Rule is a simple idea: wealthy individuals should pay a minimum tax rate of 30% on their income over $1 million. This rule is named after Warren Buffett, who famously argued that it's unfair for him to pay a lower tax rate than his secretary.
The Buffett Rule was introduced by President Barack Obama in 2011 as part of his budget proposal. It aimed to address the issue of tax loopholes and deductions that allow high-income earners to pay a lower tax rate than middle-class families.
The rule would apply to individuals with adjusted gross income over $1 million, and it would not affect tax rates for lower-income earners. This means that people who make less than $1 million would not be affected by the Buffett Rule.

What Is the Rule?
The Buffett Rule was a tax plan proposed by President Barack Obama in 2011, named after billionaire investor Warren Buffett who claimed it was unfair that he paid a lower tax rate than his secretary.
The Rule aimed to address tax code bias that forced middle-class workers to pay a larger proportion of their income in taxes than the wealthy do. Middle-class taxpayers shoulder this burden because their income primarily consists of wages that are subjected to income, payroll, and other federal taxes.
The Buffett Rule sought to remedy this bias by requiring millionaires to pay at least 30% of their post-charitable contribution income in taxes. This was a fair share tax, as it would have ensured that the wealthy paid a similar proportion of their income in taxes as middle-class families.
Warren Buffett, with a net worth of $138 billion, pays a higher share of federal income tax, but his secretary Debbie Bosanek pays a higher share of her income in Social Security taxes than Buffett does. The Social Security tax rate for employees is 7.65%, and self-employed individuals pay 15.3%.

Support and Criticism
Supporters of the Buffett Rule believed it was a step towards closing a tax loophole and making the tax code more impartial. They pointed out that the wealthy paid an average effective federal tax rate far short of the top marginal rate they should pay.
Critics of the Buffett Rule argued that it would have a chilling effect on business growth by effectively hiking the capital gains tax rate. This is because the ultra-wealthy, like Warren Buffett, make their money from investments, not salaries or wages.
The nonpartisan Tax Policy Center noted that even without the Buffett Rule, only about 4,000 people with $1-million-plus income would pay less than the 15 percent effective federal tax rate that middle-income households would also pay.
Support
Paul Krugman, a Nobel Prize-winning economist, thinks that super-low taxes on the very rich are indefensible. He points out that the US economy added 11.5 million jobs during President Bill Clinton's first term, when the capital gains tax rate was over 29 percent.
A CBS News/The New York Times poll found that 52 percent of Americans agree that investments should be taxed at the same rate as income. A Gallup poll released in April 2012 found that 60 percent of Americans support the rule.

Warren Buffett has said that certain wealthy people are undertaxed compared to the general population. Bill Gates, a close friend and colleague of Buffett's, agrees that the wealthy are not taxed enough and that this should be changed.
The Buffett Rule states that no household earning more than $1 million annually should pay a smaller share of its income than middle-class families. This rule was coined after Warren Buffett pointed out that he pays the same percentage share of income tax as his secretary Debbie Bosanek.
Studies have shown that federal income tax rates aren't as equitable as they may appear at first glance. The top 1% paid 26% of their income in federal tax in 2021, while the bottom 50% paid 3.1% in tax.
A report by the White House found that America's 400 wealthiest families actually paid 8.2% of their income in taxes, owing in large part to loopholes in capital gains taxes.

Criticism

Critics of the Buffett Rule argued that the relatively few ultra-wealthy make their vast sums of money from investments, not salaries or wages. This is because the legal tax rate applied to this type of income is the capital gains tax rate.
Critics claimed that the Buffett Rule was effectively a capital gains tax rate hike, which would have a chilling effect on business growth. The nonpartisan Tax Policy Center declared that only about 4,000 people with $1-million-plus income would pay less than the 15 percent effective federal tax rate that middle-income households would also pay.
Many critics noted that the vast majority of millionaires pay a higher ordinary income tax rate than middle class wage or salary earners.
