The US Can’t Afford Lower Taxes Without Lower Spending

Less than two months ago, projections showed the US government on track to borrow some $2 trillion this year with budget deficits exceeding 5% of gross domestic product indefinitely. Since then, this dire outlook has worsened — thanks to the Supreme Court’s ruling on tariffs, the war with Iran, the prospect of slowing economic growth and rising interest rates.

What, you might wonder, is Washington proposing to do in response? It’s debating how to cut taxes.

The latest proposals come from Senators Chris Van Hollen and Cory Booker. Both want to lower taxes for the poor and middle class while raising them for businesses and the rich. Van Hollen’s plan would be broadly revenue-neutral, with cuts of $1.5 trillion over a decade roughly offset by surtaxes on very high incomes. Booker’s would cost about $5 trillion (not counting as-yet-unspecified increases in corporate taxes). Neither gives a moment’s thought to the need for substantially more revenue.

Van Hollen calls for a new “alternative maximum tax”: Qualifying taxpayers would pay no more than 25.5% of their income above a “cost of living exemption” set at $92,000 for married couples. This would raise after-tax pay in the middle of the income distribution by roughly 3%. (The poorest pay no tax as is, so they wouldn’t see any benefit.) To make up the shortfall, there’d be a surtax of 5% on incomes above $1.5 million, 10% above $3 million and 12% above $7.5 million. The resulting top rate of 49% would be a lot higher than its average European counterpart, though it would apply to a much narrower base.
