Carried interest is the share of investment profits — typically around 20 percent — that fund managers receive as compensation for managing other people's capital. Under current law, when the underlying investments are held long enough, the manager's share is taxed at long-term capital-gains rates rather than ordinary-income rates that apply to wages and salaries.
Critics call this a loophole: the manager's carried interest is, functionally, payment for labor, yet it is taxed at rates well below those that apply to other high earners' wages. Defenders argue the treatment reflects the at-risk, equity-like nature of the position and is consistent with how partnership income has long been treated.
Reform proposals range from full reclassification as ordinary income, to extending required holding periods, to narrowly targeting specific fund structures. Estimates of revenue raised vary, but most analyses put the figure in the low tens of billions over a decade.
