Main Street Tax Certainty Act

Maddy summaryHR 703, the Main Street Tax Certainty Act, makes a key tax deduction permanent for small business owners. It removes the temporary sunset provision (subsection (i)) from Section 199A of the tax code, ensuring the qualified business income deduction remains available for eligible small businesses. This change directly affects pass-through business owners (like S-corps, partnerships, and sole proprietorships) who currently qualify for this deduction. The permanent change takes effect for tax years starting after December 31, 2025.

Strengthening our Servicemembers with Milk Act

Maddy summaryHR 648, the Strengthening our Servicemembers with Milk Act, requires the Secretary of Defense to provide a variety of milk options - including unflavored, organic, lactose-free, and different fat levels - to all members of the Armed Forces at military dining facilities. The bill mandates that installations offer these choices to support servicemember nutrition and dietary needs. It also prohibits purchasing milk from entities owned or controlled by foreign adversaries, as defined by Commerce Department regulations. This policy directly affects military personnel dining at on-base facilities nationwide.

PARTS Act of 2025

Maddy summaryThis bill amends the legal definition of "firearm silencer" and "firearm muffler" under federal law. It clarifies that these terms include any device designed to reduce firearm noise, as well as the outer tube or primary housing component that serves as the main structure for noise-reduction parts. The definition specifically covers devices intended to attach to a firearm (directly or via mounts) and excludes other firearms. This change affects how silencers are legally categorized under federal regulations, not who can own them. It does not create new restrictions but refines the scope of existing definitions.

No Taxpayer Funding for Abortion and Abortion Insurance Full Disclosure Act of 2025

Maddy summaryHR 7 prohibits federal funds from being used for abortions or health insurance plans covering abortion, with exceptions for pregnancies resulting from rape, incest, or when a woman's life is endangered. It blocks federal premium tax credits under the Affordable Care Act for health plans covering abortion (except in specified cases) and requires clear disclosure of abortion coverage and related surcharges in plan materials. The bill allows individuals or employers to purchase separate abortion coverage using non-federal funds, such as out-of-pocket payments, without affecting federal subsidies. It directly affects federal health programs, ACA marketplace plans, and health insurance issuers offering coverage that includes abortion services.

Birthright Citizenship Act of 2025

Birthright Citizenship Act of 2025 This bill limits birthright citizenship by redefining what it means to be subject to the jurisdiction of the United States. Currently, a person born in the United States and subject to U.S. jurisdiction is entitled to citizenship. Under the bill, a person is subject to U.S. jurisdiction if he or she is born to a parent who is (1) a U.S. citizen or national, (2) a lawful permanent resident residing in the United States, or (3) a non-U.S. national ( alien under federal law) with a lawful immigration status who is performing active service in the Armed Forces. The bill does not affect the citizenship or nationality status of any person born before the bill's enactment date.

To amend the Internal Revenue Code of 1986 to modify the railroad track maintenance credit.

This bill increases the annual limit on the tax credit for qualified railroad track maintenance expenses (also referred to as the short line railroad tax credit) and expands eligibility for claiming the credit. Under current law, the tax credit is limited each tax year to $3,500 multiplied by the sum of the number of miles of railroad track owned or leased by the taxpayer (miles owned or leased) and the number of railroad track miles assigned to the taxpayer by a Class II or III railroad (miles assigned). This bill increases the annual limit to $6,100 multiplied by the sum of miles owned or leased and miles assigned. The $6,100 amount used in the calculation of the tax credit limit is adjusted for inflation for tax years beginning after 2025. The bill also expands eligibility for the tax credit to include gross expenses for maintaining railroad tracks owned or leased as of January 1, 2024. Under current law, the tax credit is limited to gross expenses for maintaining railroad tracks owned or leased as of January 1, 2015.

AMERICANS Act

Maddy summaryHR 511 (AMERICANS Act) prevents the military from imposing new COVID-19 vaccine mandates without explicit congressional approval. It prohibits adverse actions like discharge or rank reduction against service members who refuse the vaccine based on personal reasons, and requires the military to reinstate separated members to their prior rank with back pay, expunge related records, and retain unvaccinated personnel equally. The bill also eliminates bonus repayment obligations for members separated over vaccine refusal and mandates equal professional development opportunities for unvaccinated service members. It directly affects military personnel impacted by prior vaccine mandates, focusing on policy changes rather than future outcomes.

Hearing Protection Act

Maddy summaryHR 404, the "Hearing Protection Act," reclassifies firearm silencers (devices that reduce gunfire noise) as firearms for federal tax and regulatory purposes. It imposes a 10% federal tax on silencers, requires the destruction of all existing federal silencer registration records within one year, and preempts state laws that tax or regulate silencers. The bill clarifies that silencers are treated as firearms under federal law, including for licensing and marking requirements, and defines "firearm silencer" to include specific components. Note: The bill’s title is misleading - it addresses firearm silencer regulation, not hearing protection for people.

Protection of Women and Girls in Sports Act of 2025

Maddy summaryHR 28, the *Protection of Women and Girls in Sports Act of 2025*, amends Title IX to prohibit federally funded schools from allowing male-identified individuals (based on biological sex at birth) to compete on women’s or girls’ sports teams. It explicitly states that such participation would violate federal civil rights law, with exceptions only for training/practice that doesn’t displace female athletes from roster spots, competitions, scholarships, or other benefits. The bill mandates a Comptroller General study to define "other benefits" lost by girls when males compete in single-sex sports, including impacts on psychological well-being, scholarship access, and safe participation environments. This bill directly affects all athletic programs receiving federal funding, requiring compliance with its biological-sex-based eligibility rules.

Title X Abortion Provider Prohibition Act

Maddy summaryThis bill prohibits federal funding under Title X (which supports family planning services) for clinics or organizations that perform or fund abortions, except in cases of rape, incest, or when a physician certifies a life-threatening condition. It requires grantees to certify compliance annually and mandates detailed annual reports to Congress on exceptions, including abortion counts by circumstance. The law directly affects Title X-funded providers who currently offer abortion services, potentially forcing them to stop providing abortions or lose federal funding. Key mechanisms include the certification requirement, exception criteria, and the new reporting obligations for the Secretary of Health and Human Services.
