The Tax Cuts and Jobs Act, which President Trump signed into law in December, did not directly affect state budgets. It cut federal tax rates, but also made other changes that mean more income will be subject to taxation. Because most states use federal definitions of income and have not adjusted their own rates, the federal changes will have big consequences for both state budgets and taxpayers.

President Donald Trump complains that large corporations, such as Amazon.com Inc., are shirking their tax responsibilities. Yet for at least a decade, Trump paid none or very little in federal income taxes by exploiting some of the same generous tax breaks that the online retail giant and others have used to reduce IRS bills.

Basically what is being promised by the Trump team doesn't match the plan unveiled in September. Economist are not clear of the effects. They claim that cutting corporate taxes will bring back jobs but experts can not reach the same conclusion when they run the numbers
