Why the hell should anyone earning under $20,000 a year be taxed at all?
This^^^
We need a standard deduction payroll tax.
Comparatively to other countries (adding state corporate taxes), your corporate tax is a bit high. Deductions, expenditures and loopholes are rampant, obviously, but if we are assuming a nearer to perfect no-evasion world. 30%+12% in IA would be 42%.
Personally, I would just say scrap the corporate tax. Too much complexity. Too little benefit. Let's get Liz's Wealth Tax or a shareholder tax to pick up the fiscal gap (and probably more).
Bleh to broad-based VAT without a rebate.
