But there is one financially sound reason Trump chose to break this popular promise and leave "no tax on Social Security" out of the One, Big, Beautiful Bill: It would have substantially worsened the program's long-term outlook.

The bill passed by the House would raise the standard deduction by up to $4,000 for those 65 and over, starting in 2025 to 2028.

The House bill’s proposed $4,000 senior deduction falls short of eliminating taxes on Social Security benefits altogether.
