Wealthy Americans will pay lower taxes. Scott Barbour / Stringer / Getty Images Consumer Reports has no financial relationship with advertisers on this site. The Senate passed its version of a wide-ranging tax bill (PDF) early Saturday, with Republicans characterizing it as a win for middle-income taxpayers and for businesses that will help grow the American economy. But the final bill, which was amended up until the vote at 2 a.m. Eastern Standard Time, shows some clear winners and losers. It also differs from the House version passed in mid-November. The two plans would need to be reconciled and approved by each chamber. Several measures in the Senate plan could help middle-income taxpayers, at least for the first few years after the bill's enactment. It eliminates the $4,050-per-person personal exemption, and it doubles the standard deduction—meaning more people and families could end up with no federal tax bill, and others could see larger refunds. Supporters say that the significant drop in corporate taxes from a top 35 percent to a flat 20 percent—along with other changes to business taxation—would spur significant improvements in the economy and job market overall. That's in spite of estimates that the bill would add more than $1 trillion to the deficit after 10 years. Critics say the plan would benefit corporations and the wealthy at the expense of the poor and lower earners. They say the deficit caused by the bill would eventually require painful cuts in public services, as well as in entitlements such as Medicare. Here's a breakdown of who would be most likely to win and lose if the changes become law: Likely winners • Those who take the standard deduction. Most individuals and families taking the standard deduction would see a tax break under the plan, according to multiple analyses. For those who itemize, it's less certain that their tax burden would go down. The nonpartisan Tax Policy Center puts the average tax benefit for households making $50,000 to $75,000 at $850. (The U.S. median household income is around $59,000.) "If you're taking the standard deduction now, you'll most likely get a tax break," says Michael Kresh, a certified
