Part of the reason so many Americans don’t pay federal income taxes is that Republicans have passed a series of very large tax cuts that wiped out the income-tax liability for many Americans. That’s why, when you look at graphs of the percent of Americans who don’t pay income taxes, you see huge jumps after Ronald Reagan’s 1986 tax reform and George W. Bush’s 2001 and 2003 tax cuts. So whenever you hear that half of Americans don’t pay federal income taxes, remember: Ronald Reagan and George W. Bush helped build that.
