Direct File Act of 2026

Maddy summaryThis bill, known as the Direct File Act of 2026, would establish a government-run online platform for taxpayers to prepare and file their individual income tax returns for free. It requires the Treasury Department to create a user-friendly system that uses IRS data to simplify the process, offers customer support, and is available in multiple languages and on mobile devices. The legislation also prohibits the Treasury from entering into agreements that would limit its ability to provide these tax preparation and filing services. Additionally, the bill allows eligible states to integrate their state tax filing with the federal system and provides funding to states that meet certain standards for doing so.

ROTOR Act

Rotorcraft Operations Transparency and Oversight Reform Act or the ROTOR Act This bill addresses aviation safety by increasing requirements for aircraft tracking and communication using Automatic Dependent Surveillance-Broadcast (ADS-B) technology and expanding oversight. As background, ADS-B for broadcasting (Out) and receiving (In) transmits information (e.g., location and weather information) between aircraft and air traffic control. Under the bill, aircraft must generally operate with ADS-B In equipment to provide the aircraft with location information of other aircraft and traffic advisories. Current law does not require this equipment. Current Federal Aviation Administration (FAA) regulations allow aircraft performing a sensitive government mission to be excepted from requirements for using ADS-B Out equipment. This bill limits which flights may be considered sensitive government missions (e.g., not training flights) and requires additional reporting and notifications for the exception. The Government Accountability Office must review the use of the ADS-B Out exception and the Office of the Inspector General (OIG) of the Department of Transportation must annually audit FAA oversight of operations that use the exception. Further, the bill repeals a 2025 law that exempts certain military helicopters from the ADS-B Out requirements for the Washington, DC, metropolitan area. The bill also requires the OIG of the Army to audit the Army’s coordination with the FAA, the FAA to establish an office to coordinate airspace usage of military aircraft and review the safety of flight operations and routes around airports, and the FAA to enter into memoranda of understanding with military agencies for safety information sharing.

A concurrent resolution recognizing the 15th anniversary of the January 8, 2011, Tucson, Arizona, shooting and honoring the survivors and victims, including former Congresswoman Gabby Giffords, a gun violence survivor and one of the most influential voices of courage in the United States in the fight to end gun violence.

It honors the victims (such as Judge John Roll, Gabriel Zimmerman, and 9-year-old Christina-Taylor Green), survivors like Giffords and Ron Barber (who later became a U.S. Representative), and the community's response. The resolution expresses support for survivors, recognizes Giffords’ advocacy against gun violence, and reaffirms commitment to respectful dialogue and opposing political violence. As a symbolic gesture, it does not enact new laws or policy changes.

Fiscal Harms of Federal Firing Act

Maddy summaryThis bill requires the Government Accountability Office (GAO) to study how federal workforce reductions (like large-scale layoffs) impact state and local government budgets.

The GAO must complete this study within 18 months and submit a public report to Congress, including findings, recommendations for supporting displaced workers and affected governments, and potential policy options. The bill does not change current policies but mandates a comprehensive assessment of fiscal consequences.

The bill is procedural, establishing concrete pay rate adjustments without altering broader employment policies.

Ending Improper Payments to Deceased People Act

Ending Improper Payments to Deceased People Act This act permanently allows the Department of the Treasury to access certain death records maintained by the Social Security Administration (SSA) to help prevent and recover improper payments (e.g., payments to deceased individuals). The act also establishes evidentiary requirements the SSA must meet before identifying an individual as deceased. Current law requires the SSA to share its Death Master File with the Do Not Pay system maintained by Treasury for three years. The act makes this requirement permanent. Treasury must enter into an agreement with the SSA related to Treasury's share of the cost of state death data. The act also prohibits the SSA from recording a death in the master file unless the SSA has clear and convincing evidence that the individual should be presumed deceased. If an individual is incorrectly identified as deceased and provides the SSA with supporting documentation, the SSA may notify certain agencies that have access to the master file, including Treasury and federal or state agencies that provide or disburse federally funded benefits.
