Presidential candidate Ted Cruz’s tax proposal would (1) repeal the corporate income tax, payroll taxes for Social Security and Medicare, and estate and gift taxes; (2) collapse the seven individual income tax rates to a single 10 percent rate, increase the standard deduction, and eliminate most other deductions and credits; and (3) introduce a new 16 percent broad-based consumption tax. The plan would cut taxes at most income levels, although the highest-income households would benefit the most and the poor the least. Federal tax revenues would decline by $8.6 trillion (3.6 percent of gross domestic product) over a decade.
