2024 Income Tax Brackets Single Filer. For 2023, the highest earners in the united states pay a top rate of 37% federal tax on all income. The next tax bracket is 12% of taxable income levels.
Currently, there is no 40% tax bracket. For example, a hypothetical single filer would owe 10% on the first $11,600 of taxable income in 2024 whether that amount represents their total earnings, or they earn $1 million.
