Income taxed at long-term capital gains rates is not taxed independently of your other income. The income taxable at LTCG rates sits on top of all of your income that is taxed at ordinary income tax rates. This means that the LTCG tax bracket that applies to a particular dollar of LTCG will be affected by how much ordinary taxable income your have. If any of your income taxed at LTCG rates is being taxed at a rate above 0% on your 2023 tax return, it means that you have more than $44,625 of taxable income on Form 1040 line 15.
