Last week, House Speaker Paul Ryan said in a CNBC interview that the distributional analysis of tax plans done by the Tax Policy Center, the Joint Committee on Taxation, and others is based on the “ridiculous notion” that the effect of tax changes on different income groups is important.

Democratic presidential hopeful Hillary Clinton would raise taxes on businesses and high-income households while making minimal changes to the after-tax incomes of those with low and moderate incomes, according to a new analysis by the Tax Policy Center. Overall, Secretary Clinton would boost federal revenues by $1.1 trillion over the next decade. Those changes would make the tax code more complex, especially for high-income households, and would reduce incentives to work, save, and invest.

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.
