<prompt> Human: I understand that when your gross income brings you into the top tax bracket long term capital gains go to 20 instead of 15. I have 2 questions about this.1 Can capital gains themselves bump you into that bracket?2 If they can is it a marginal increase only on the gains above 470kish, married? Basically: Do you need to be extra cautious about taking capital gains that might bring your AGI over the threshold because it increases the tax rate 5 on all gains, or is it only 5 higher on the excess?  <response>: 1 yes2 only on the excess
