You are wrong. First, let's state that you are referring to taxable income, not gross income. The former is usually non-trivially smaller than the latter, due to adjustments (including pre-tax paycheck deductions) and itemized/standard deduction. Using 2023 numbers (since we don't know whether 2024 tax law will change between now and the end of the year), and your dollar amounts: $400K of ordinary taxable income tops out at 35% marginal rate, the total tax is $111,895. $120K of LTCG income is taxed as follows: $92,300 x 15% = $13,845 $27,700 x 20% = $5,540 Total LTCG tax = $19,385 (the 2023 LTCG 15% bracket tops out at $492,300)
