How does the 'big, beautiful bill' help middle-class taxpayers?

Republican lawmakers last week managed to overcome narrow majorities in the House and Senate to pass the One Big Beautiful Bill Act — a package of tax and spending reforms the Trump administration made a priority upon the start of the president's second term.

The bill addressed a wide range of tax and spending policies, though its main focus was on the extension of provisions within the Tax Cuts and Jobs Act of 2017 that were set to expire at the end of this year, which would have left many taxpayers facing an automatic tax hike.
