Double benefit from a tax deduction

Description

Abstract: For most taxpayers, the amount of federal income tax they pay depends on where they fall in the federal income tax brackets and the breakdown of their taxable income between ordinary (e.g., wages) and capital gains from the sale of assets (e.g., common stock). As federal taxable income decreases, the rate of tax on at least a portion of that income also decreases. In addition, if a taxpayer has a long-term capital gain that, after considering ordinary income, is partially taxed at the 0% rate, any additional deduction that decreases ordinary income will simultaneously decrease the tax rate on a comparable amount of long-term capital gain to 0%. This has the effect of producing a double benefit for that deduction. This article offers an example.
