Hillary Clinton to propose increasing capital gains taxes as part of 2016 campaign plans

Hillary Rodham Clinton plans later this week to propose raising capital gains taxes for some investors. It's part of her effort to encourage greater focus on longer-term economic growth.

The new rates would be pegged to the duration of the investment, with short-term holdings taxed at a higher percentage.

Earlier this year, President Barack Obama proposed raising the 23.8 percent capital gains rate to 28 percent for the highest earners. While Clinton's proposal is still being finalized, her rate would likely be higher for the shortest-held investments. That's according to a campaign official who spoke anonymously to discuss plans still being developed.

The plan is part of a larger package aimed at tackling what Clinton says is too heavy an emphasis on immediate corporate gains at the expense of workers.
