HF 2785: A bill for an act extending the biodiesel blended fuel tax credit.

This Iowa bill extends the expiration date for the biodiesel blended fuel tax credit from January 1, 2028, to January 1, 2033. The change directly affects retail dealers who sell biodiesel fuel blends, allowing them to continue claiming a state income tax credit for promoting these fuels. By updating the relevant tax code sections, the legislation ensures that dealers whose tax years do not align with the original repeal date can still claim the credit for a full calendar year. The bill also clarifies how the credit amount should be calculated for dealers claiming it in the year following the extension period.

HF 2786: A bill for an act modifying the sales or use tax refund for biodiesel production.

This Iowa bill modifies the state tax refund program specifically for biodiesel producers. The legislation increases the refund rate from four cents to five cents per gallon of biodiesel produced within the state. It also extends the expiration date for this tax benefit from January 1, 2028, to January 1, 2031. These adjustments apply to the total number of gallons produced by eligible producers during each quarter of a calendar year.

HF 2104: A bill for an act relating to the exercise of eminent domain for carbon oxide pipelines, and including applicability and effective date provisions.

HF 2104 prohibits the use of eminent domain (government power to take private property) for pipelines primarily transporting carbon oxide. It directly affects pipeline companies seeking to acquire land for new pipelines by banning this specific method of land acquisition. The bill amends Iowa law to state that no person may exercise eminent domain for building or operating such pipelines, effective immediately upon enactment. This applies to all condemnation cases filed on or after the effective date, preventing new carbon oxide pipeline projects from using this legal process to secure right-of-way.
passed · Iowa · House Mar 26, 2026

HF 2618: A bill for an act eliminating the Iowa smart planning principles and other local comprehensive planning and development guidelines.

HF 2618 repeals Iowa's "smart planning principles" (sections 18B.1 and 18B.2), which required local governments and state agencies to consider 10 specific guidelines in planning, zoning, and development decisions. The bill removes these requirements from state code, eliminating the obligation for cities, counties, and state agencies to reference or apply these principles when creating comprehensive plans, zoning regulations, or infrastructure projects. It also deletes related references from other sections of Iowa law governing regional planning (28I.4), airport zoning (329.3), and local development regulations (335.5, 414.3). This change directly affects how local governments approach land use and development planning across Iowa.

HF 2529: A bill for an act providing for the repair of a diesel exhaust fluid system that is part of farm equipment, and providing penalties.

HF 2529 requires manufacturers of farm equipment with diesel exhaust fluid systems to provide owners (farmers, lessees, or licensees) with free diagnostic and repair information, including software updates, on the same terms they offer to their authorized repair providers. It also mandates that manufacturers make replacement parts and diagnostic tools available for purchase at fair, reasonable prices comparable to those offered to authorized repair providers in the same region. The bill does not force manufacturers to disclose trade secrets or override existing agreements, but voids contracts that waive these new rights. This directly affects farmers who operate diesel-powered agricultural equipment requiring emissions control systems.
passed · Iowa · House Mar 10, 2026

HF 989: A bill for an act relating to animal feeding operations, by providing for the regulation of anaerobic digester systems, providing fees, making penalties applicable, and including effective date and applicability provisions.

HF 989 establishes a new regulatory framework for anaerobic digester systems used in animal feeding operations. The bill defines various terms related to these systems, including digester manure, feedstock, and digestate. It grants a state department the authority to create rules for the on-farm construction, expansion, storage, stockpiling, and application of materials associated with anaerobic digesters. These regulations aim to manage organic materials originating from animal feeding operations, and the bill also provides for fees and applicable penalties.

HF 860: A bill for an act prohibiting state and local regulations on fuel-powered equipment based on the equipment’s fuel source.

HF 860 prohibits state and local governments from enacting regulations on fuel-powered equipment. Specifically, it prevents these governmental bodies from creating rules based solely on the equipment's fuel source. This means state and local authorities can no longer implement policies that differentiate or restrict machinery because of the type of fuel it consumes.
