How progressive is the US tax system compared with other countries?
Core argument: Across all federal taxes, the top-earning U.S. quintile paid $3.2 trillion, while the next three quintiles paid $655 billion, $278 billion and $81 billion, and the bottom quintile paid negative $20 billion.
OECD data reveal that the U.S. has the most progressive income and payroll taxes of any OECD nation—even after adjusting for income distribution across countries. America taxes the wealthy within international norms but taxes lower and middle earners far less than other nations (not to mention not imposing value-added taxes). Thus, the wealthy overwhelmingly fund the federal government. Across all federal taxes, the top-earning quintile paid $3.2 trillion, while the remaining four quintiles paid $655 billion, $278 billion, $81 billion, and negative $20 billion, respectively (see Figure 2). Put another way, the top-earning quintile funded 201 days of 2024 federal spending, the next quintile funded 41 days, and the bottom-earning 60% of families collectively funded 21 days of spending (the remaining 103 days were financed with budget deficits and borrowing). The notion that middle-earner taxes finance the federal government, while most wealthy families escape taxes, is simply preposterous.
