Maddy summaryHB 3088 bans specific clauses in health care provider network contracts that limit patient choice and transparency. It prohibits providers from including "anti-steering" (restricting patient referrals to specific providers), "anti-tiering" (blocking tiered pricing systems), "gag" (hiding price/quality data), or "most-favored-nation" (forcing equal rates across insurers) clauses. Any existing contract with these clauses becomes void, while insurers must act in patients' best interests when designing networks. This directly affects health care providers, insurers, and the patients covered by health benefit plans.

Maddy summaryHB 2888 limits claims for future medical monitoring in civil lawsuits. It states that merely having a toxic substance in the body (without a diagnosable disease) doesn't qualify for compensation. To recover future monitoring costs, plaintiffs must prove: (1) the monitoring is directly tied to a current, diagnosed illness; (2) it goes beyond standard care; and (3) the illness was caused by the defendant's negligence. This bill directly affects individuals filing lawsuits related to exposure to harmful substances, such as environmental or workplace toxins.
Maddy summaryHB 2715 modifies Missouri's anti-discrimination law by allowing mandatory retirement at age 65 for executives or high policy-makers who meet specific pension requirements ($44,000+ annual benefit). It also clarifies that current illegal drug use does not count as a disability under the law, except for individuals in rehabilitation programs or successfully rehabilitated. The bill directly affects employers (including state entities), employees, and disability discrimination complainants by changing eligibility for protections and retirement policies. These changes refine definitions of "disability" and "age" in employment discrimination cases without altering broader anti-discrimination coverage.
Maddy summaryHB 2716 creates a Missouri state tax credit for eligible rail entities to cover certain railroad infrastructure costs. It allows short-line railroads (Class II/III), rail siding owners, or port/city rail authorities to claim a 50% credit against their state tax liability for qualified maintenance, reconstruction, or new rail infrastructure expenses like tracks, bridges, or industrial spurs. The credit is capped annually at $4.5 million for maintenance costs and $10 million for new infrastructure projects, with unused credits carryable for up to five years. Taxpayers must submit a certificate to the Missouri Department of Economic Development detailing eligible expenses and track miles, with credits allocated in the order claims are received if annual limits are exceeded.
Maddy summaryHB 1041 changes Missouri's inspection and gauging fees for malt liquor barrels based on whether the product is domestically produced or imported. For tax years ending before 2026, the fee is $1.86 per barrel regardless of origin. Starting in 2026, domestic malt liquor producers will pay $0.62 per barrel, while imported malt liquor will remain at $1.86 per barrel. This bill directly affects malt liquor manufacturers, importers, and distributors who must maintain records showing the country of origin for imported products. The key change is creating a lower fee for domestic producers compared to imported products beginning in 2026.
Maddy summaryHB 642 creates a 25% tax credit for small meat processing facilities in Missouri that modernize or expand operations. It directly affects small businesses (employing fewer than 500 people total across all facilities) that invest in qualifying equipment, buildings, or technology for meat processing. The credit covers 25% of eligible expenses (like processing equipment or facility upgrades), with annual limits of $75,000 per business and $2 million total statewide. The credit expires December 31, 2028, and requires applications through the Agricultural and Small Business Development Authority.
Maddy summaryHB 1042 modifies Missouri's income tax calculation for farmers by requiring them to add back certain federal tax benefits previously deducted from their Missouri taxable income. Specifically, it mandates adding back federal tax refunds (excluding pandemic-related credits), interest on some government bonds, and specific federal deductions like depreciation on farm property purchased between 2002-2003. This directly affects Missouri farmers who claimed these federal deductions, as it increases their Missouri taxable income for those items. The bill clarifies how these adjustments are calculated but does not change the underlying federal tax rules.
Maddy summaryHB 1519 modifies Missouri's wine excise tax rate from $0.30 to $0.21 per gallon and redirects the revenue to a new "Missouri Wine and Grape Fund." This fund, created by the bill, will be used exclusively for developing the state's wine industry - funding marketing, grape-growing programs, viticulture experts, and wine-related business development. The tax applies to wine sellers in Missouri, with funds deposited starting July 1, 2026, and managed by the Department of Agriculture. The bill does not change penalties for tax violations or other liquor tax provisions.
Maddy summaryHB 535 designates the rhinoceros as Missouri's official state zoo animal. This symbolic bill, which has been prefaced and read in committee, does not create new laws or affect any policies, people, or regulations. It solely serves as a ceremonial designation for the state's zoo animal, with no practical impact on residents or state operations. As a procedural resolution, it has no substantive policy changes or real-world consequences.
Maddy summaryHB 537 exempts certain vehicle dealers from place-of-business inspections. Specifically, it removes requirements for agricultural supply retailers under common ownership with at least five other dealers operating under the same name. These dealers no longer need to submit annual certifications, photos of their business location, or meet minimum sales thresholds tied to a "bona fide established place of business." The change applies to new and used motor vehicle, boat, and trailer dealers in this category.
