We should instead make capital gains regressive over time, based upon how long the capital is invested in a company. Taxes on short-term investments should continue to be taxed at personal income rates. But the rate should be reduced the longer the investment is held — so that, for example, tax rates on investments held for five years might be zero — and rates on investments held for eight years might be negative.
Federal tax receipts from capital gains comprise only a tiny percentage of all United States tax revenue. So the near-term impact on the budget will be minimal. But over the longer term, this policy change should have a positive impact on the federal deficit, from taxes paid by companies and their employees that make empowering innovations.
