Now that the Iowa Caucuses and the primaries in New Hampshire are over, the field of Republican presidential candidates has been narrowed down to just six:

  • Donald Trump
  • Sen. Ted Cruz
  • Sen. Marco Rubio
  • Dr. Ben Carson
  • Gov. Jeb Bush
  • Gov. John Kasich

All six have released tax plans -- some with extremely specific details, some a lot more vague. Some of the candidates are proposing relatively moderate changes, such as lowering the top income tax brackets and reducing taxes on businesses. Others are suggesting more radicalĀ  reforms, such as throwing out the current tax code and replacing it with one so simple that people could file their annual tax return on a postcard.

With that in mind, here's what we know so far about where the Republicans stand on tax reform.
