Americans’ support for the tax changes signed into law by President Donald Trump late last year has edged up to 39% from 33% in January and 29% in December before the bill was passed. But more Americans continue to disapprove than approve of the law.

The results are based on a Feb. 26-March 4 Gallup poll, the first taken after many organizations began to lower income tax withholding in worker paychecks. Trump touted the law in his Jan. 30 State of the Union address, and leaders in both parties have made the tax cuts an issue in this midterm election year. While these events may have had some effect, none of these developments has fundamentally changed Americans’ more negative than positive opinions of the tax law.
