If Bernie Sanders is elected his tax plan would raise taxes by $15.3 trillion over ten years, and would threaten the charitable giving breaks.

"The laundry list of tax hikes proposed by Democratic presidential candidate Bernie Sanders would raise $15.3 trillion over the next decade by increasing taxes at least a little at all income levels, and hitting the very rich, and in particular their capital gains and charitable giving, with huge tax hikes, a new analysis by the nonpartisan Tax Policy Center shows.

"If all of the Vermont senator’s changes were in place in 2017, households would, on average, pay almost $9,000 more in taxes, reducing their after tax income by 12.4%,  TPC figures.  But that average masks a plan that goes all out to tax the rich, including their dividends and capital gains, which now benefit from special lower rates.  By TPC’s figuring,  the poorest fifth of taxpayers would pay an average of just $165 more per household in 2017, raising their average federal tax rate by 1.2 percentage points to 5.3%. The middle fifth would pay an average of $4,692 more, as their average federal rate rose 7.3 percentage points to 20.8%."--Janet Novak, Forbes
