Democratic presidential hopeful Bernie Sanders has proposed a tax increase of $15.3 trillion over the next decade, according to a new analysis by the Tax Policy Center. The tax hikes– which would help finance Senator Sanders’ ambitious new spending programs for health care, education, and family leave–would be the largest since World War II.

How do the Republican presidential candidate tax plans stack up against one another? Who has the biggest tax cut? How do their plans affect people in different income groups?

GOP presidential hopeful Ted Cruz’s aggressive plan to shift the tax code from a mostly income-based system to one based on consumption would slash federal revenues by $8.6 trillion over the next decade, according to a new Tax Policy Center analysis. Including interest costs, it would add $10.2 trillion to the debt over 10 years unless Cruz offsets his tax cuts with unprecedented reductions in federal spending. By 2036, Cruz’s plan would add nearly $30 trillion to the debt.
