For investors, fall is a good time to review year-to-date gains and losses. Doing so can help you determine whether to buy or sell investments before year end to save taxes. You also need to consider the TCJA. While it didn’t change long-term capital gains rates, it did change the tax brackets. For 2018 through 2025, these brackets are no longer linked to the ordinary-income tax brackets for individuals. So, for example, you could be subject to the top long-term capital gains rate even if you aren’t subject to the top ordinary-income rate.
