The Privacy Act Modernization Act of 2025 aims to update the Privacy Act of 1974 by revising key definitions to address contemporary data practices. It expands the definition of an "individual" to include U.S. persons and those in the United States, while redefining a "record" as any personally identifiable information processed by an agency. The bill also broadens "system of records" to include data maintained by or for an agency, and clarifies that "personally identifiable information" includes data linked to individuals or their devices, with "process" encompassing various data operations.

The legislation strengthens protections for individuals by requiring that agency collection, use, and disclosure of records be appropriate and reasonably necessary for government functions and consistent with stated purposes. Agencies must now identify the legal authority for each data use and make reasonable efforts to ensure that disclosed records contain the minimum amount of information necessary. Additionally, it amends rules for matching programs to prevent research or statistical data from being used for adverse decisions against individuals or federal personnel.

To enhance enforcement, the bill expands civil remedies, allowing individuals or other entities to sue for any non-compliance that could lead to an adverse effect. Courts may now award preliminary and equitable relief, and if an agency acts intentionally or willfully, the United States could be liable for actual damages (including nonpecuniary), a minimum of $1,000, attorney fees, and punitive damages. Criminal penalties are also significantly increased, with new felony charges for intentional misuse of records for commercial gain, personal benefit, or malicious harm, carrying fines up to $250,000 and 10 years imprisonment.

Most amendments in this Act will take effect two years after enactment. However, provisions related to specific entities, such as the United States DOGE Service and associated personnel or matching programs involving them, will become effective immediately upon enactment. A rule of construction clarifies that the Act does not create inferences regarding the interpretation or legality of the existing Privacy Act.
