With the signing of the budget and tax bill—also known as the “One Big Beautiful Bill Act”—by President Trump on July 4, 2025, the federal government has decided that it will not attempt to preempt various state efforts to regulate the use of artificial intelligence (AI) technologies. While prior versions of the budget and tax bill (the Budget Bill) contained a purported moratorium on enforcement of existing state laws or regulations on various AI technologies or the future promulgation of new state AI laws, the final version did not contain that provision. This development is particularly relevant for healthcare and life sciences entities that employ AI technologies in product development or in the delivery of clinical care in states that have enacted regulations on AI use.

A tax authority is a government body or agency responsible for collecting taxes, administering tax laws, and enforcing tax compliance. In the United States, the Internal Revenue Service (IRS) is the federal tax authority. Most states, territories, and local jurisdictions also have tax authorities to ensure compliance with applicable state and local laws and regulations. These tax authorities are generally responsible for collecting taxes, administering tax laws, and enforcing tax compliance in their respective jurisdictions.
