Tax law changes

Thanks Champ.  Took a look and seems it is not answering what I am trying to understand.  Let me try another angle:  The "Annual Taxable Income" used by the Tax Bracket Calculator to calculate the marginal tax rate, does it include Dividends and Capital Gains?

 

Asking because we know that the tax rates for Ordinary Income are not applied to Dividend and Capital Gains income as the latter two have a separate set of brackets for determining the income tax on those earnings.  So are the tax rates for Ordinary Income, as set forth in the "brackets", only determined by the amount of Ordinary Income we have?

 

Again, thanks in advance, Think57
