http://www.johnkerry.com/issues/economy/Kerry favors keeping the tax cuts for those making less than 200,000 per year. (So does Bush, but Bush will also keep the tax cuts for the rich).
Kerry favors keeping dividend and capital gains tax cuts for those making less than 200,000 per year.
Kerry favors maintaining the estate tax, but raising the exemption to $4 million per couple and $10 million per family farm/business.
Kerry will cut corporate tax rate by 5%. This will be funded by eliminating the tax deferal on foreign income.
Kerry is also proposing a one year tax holliday (10%) for domestic reinvestment.
The new jobs tax credits indeed won't cut a company's taxes if it doesn't plan to hire new US workers. It will only apply to sectors impacted by outsourcing, and businesses that employ less than 100 people. For a whole lot of small businesses, it will indeed be a tax cut.
There are also tax credits associated with Kerry's health care, energy, education and child care policies. A whole lot of Americans would regard those as real tax cuts. See the leaflet on pro-jobs, pro-family tax cuts:
