The effects of Bush's decision not to reduce the alternative minimum tax rates are not taken into account on the "Bush Tax Calculator" on Bush's website, causing the "calculator" to hugely overstate Bush's tax cuts for families earning from about $60,000 up to the calculator's $100,000 limit. The effects abate at very high incomes.
Notes: Itemized deductions shown above, including state and local taxes deducted net of refunds, are estimated actual averages for couples that itemize deductions in 1999. Figures assume extension of the rule allowing personal credits against the alternative minimum tax under both current law and the Bush plan.
