Answer:
Qualified dividends are not considered ordinary income, they are considered capital gains. Ordinary dividends are considered ordinary income.
Since qualified dividends are considered capital gains, they should be taxed at the capital gains rate: 0%, 15% or 20%.
Currently there is no 25% tax bracket, there is a 22% and a 24% tax bracket, but any of them qualifies for the 15% capital gains tax rate.
So Yolanda's qualified dividends will be taxed at 15% rate = $2,000 x 15% = $300 tax liability.
