Should the wealthy pay a higher tax rate than they currently do?

Should the wealthy pay more? I'll weigh the case for and against with current rates and competing economic views.

Whether the wealthy should pay a higher rate than they do now is a normative question that depends on goals - reducing inequality and raising revenue vs. maximizing growth and investment - but current data and arguments on each side can be summarized:

What the wealthy currently pay

The U.S. federal income tax is progressive, which means the rate increases as taxable income goes up.

For tax year 2025:

•The top rate remains 37% for individual single taxpayers with incomes greater than $626,350 ($751,600 for married couples filing jointly)

•The other federal rates are 10%, 12%, 22%, 24%, 32%, 35%, and 37%

How income is earned matters:

•Investments and businesses constituted 82% of income for the top 0.01% and 88% for the top 0.001% in the most recent data, compared to just 7% for the bottom 80% of households

•Wages face heavier taxation than capital income, and as a result, the tax share of income paid by the very highest-income households is often lower than for middle-class households

•Specifically, the highest effective marginal income tax rates on wages exceed 40%, whereas much business income is taxed at a top rate below 30%, dividends and realized capital gains are taxed below 25%, and unrealized gains are not taxed until they are sold

One study found total effective tax rates for the 400 wealthiest Americans fell from 30% in 2010-2017 to 23.8% in 2018-2020.

Arguments for a higher rate on the wealthy

1.Revenue and inequality without harming growth: One report found that modestly raising the top marginal tax rate would raise revenue and decrease inequality without stifling growth. It estimated that making the TCJA's top marginal rate of 37% permanent, instead of allowing the top rate to revert to 39.6% as current law requires, would reduce annual federal revenue by approximately 2.24 percent after 10 years, but would not boost growth.

2.Tax cuts for the rich don't boost the economy: A separate cross-country study found tax cuts for the rich "do not have any significant effect on economic growth and unemployment", and "lead to higher income inequality".

3.Ability to pay and fairness: Proponents argue that wealth contributes directly to well-being over and above the consumption it can finance, so the wealthy have a greater ability to pay. Public opinion polling has found by two-to-one (44% to 22%), the public says that raising taxes on incomes above $250,000 would help the economy rather than hurt it, while 44% says a tax increase on higher incomes would make the tax system more fair.

4.Fiscal proposals: Economists Peter Diamond and Emmanuel Saez have suggested the viability of a top marginal federal income tax rate of 76 percent. Other proposals to shift the burden to the wealthy without just raising the income rate include capital gains reform such as eliminating step-up basis at death, taxing intergenerational transfers, eliminating the Section 199A deduction for qualified business income, and creating a value-added tax (VAT) coupled with support for low-income households.

Arguments against a higher rate on the wealthy

1.Laffer Curve and revenue: The Laffer Curve is a hump-shaped curve showing tax revenue as a function of the tax rate. The principle is that larger taxes are going to have multiple negative effects and higher taxes do not always mean more revenue. If rates are too high, taxable income can fall enough to offset the rate increase.

2.Mobility and capital flight: Critics argue people, investment capital and businesses are mobile and can leave tax-unfriendly jurisdictions. One analysis cited that from 1998 to 2007, more than 1,100 people every day moved from the nine highest income-tax states such as California, New Jersey, New York and Ohio and relocated mostly to the nine tax-haven states with no income tax.

A state-level example often cited: After Maryland created a higher tax bracket for millionaires, the number of Marylanders with more than $1 million in taxable income who filed by the end of April fell by one-third, to about 2,000, and taxes collected declined by roughly $100 million, with some taxpayers reportedly moving a few miles to Virginia or Pennsylvania to avoid the rate.

3.Investment and growth effects: Higher taxes on capital income negatively affect both the amount of available capital and willingness to take risks. Some research also finds reducing inequality through taxation between median and high-income households reduces economic growth due to changes in small business activity and labour supply.

4.Complexity and avoidance: The wealthy can finance consumption without paying capital gains by following a "buy, borrow, die" strategy, in which they finance current spending with loans and use wealth as collateral, avoiding realizing gains. Simply raising the marginal rate on wages may not capture that wealth and can create incentives to re-arrange income.

Bottom line

If the primary goals are reducing after-tax inequality, raising federal revenue to fund programs or reduce debt, and addressing the fact that capital income is taxed more lightly than wages, many economists argue a higher effective rate on the wealthy - especially through reforms to capital gains, business income, and estate taxation - would achieve those goals.

If the primary goals are maximizing investment, entrepreneurship, economic growth, and preventing tax avoidance or relocation, others argue higher rates are counterproductive and alternative reforms that broaden the base or tax consumption may be more efficient.

The choice typically comes down to how you weigh equity and revenue needs against efficiency and behavioral responses to higher rates.
