No. 1: Capital gains taxes in 2015 are unchanged from 2014
Good news, taxpayers: Although the government has enacted a number of tax changes in 2015, the capital gains tax rate is staying the same.

If you sell investments that are held for less than a year, you'll pay your income tax rate on your gains, which ranges between 10% and 39.6%.

 

On the other hand, long-term capital gains are taxed at a rate of 0%, 15%, or 20%, depending on which marginal tax bracket you fall into. Usually, consumers in the 10% or 15% marginal tax bracket pay no long-term capital gains taxes. The bulk of the population will pay a 15% long-term capital gains tax in 2015. The 20% tax rate was introduced last year and only applies to taxpayers that fall into the highest marginal tax bracket of 39.6%. Although the income qualifications for the 39.6% brackets have adjusted higher by about 1.5% in 2015, the tax rates themselves are unchanged from the previous year.
