Misinformation about the One Big Beautiful Bill Act (#OBBBA) was rampant even before President Donald Trump signed it into law on Thursday, July 4, 2025. Taxpayers and TikTokers posted articles mistakenly touting provisions that didn’t make the final cut. (One dropped provision, for example, allowed Medicare Part A beneficiaries to contribute to Health Savings Accounts.) Worse, misinformation was spread by the government itself—#Trump falsely claimed the law “eliminates” taxes on Social Security benefits, and a misleading mass email from the Social Security Administration added to the confusion. The problem is that OBBBA is an 800+ page bill with dozens of complicated tax and other provisions–some permanent and some temporary; some delayed and some retroactive; some familiar and some entirely new.
