Only one in five U.S. taxpayers expects to pay less income tax this year as a result of the tax reform law passed in 2017 by Republicans who promised big savings for everyday Americans, according to a Reuters/Ipsos opinion poll released on Friday.

The poll suggested that the tax overhaul, mostly geared to helping businesses, may not be as strong a 2020 campaign talking point as Republicans and President Donald Trump had hoped. The U.S. Treasury Department insisted that most Americans were paying lower taxes under the new law.

Just prior to approval of the tax reform by the Republican-controlled Congress, Trump said, “This is going to be one of the great gifts to the middle-income people of this country that they’ve ever gotten for Christmas.”
