The purpose of this legislation, known as the FAIR PREP Act of 2025, is to change how the U.S. Treasury Department handles the preparation of tax returns. Specifically, it aims to prevent the Secretary of the Treasury from preparing tax returns and claims for refunds, which is intended to promote taxpayer autonomy and reduce government involvement in tax preparation. Key provisions of the Act include a clear prohibition on the Secretary of the Treasury preparing any tax returns or refund claims, except in certain circumstances defined by existing law.
