Sen. Marshall: 45Z Tax Credit Now Limits Eligibility for Biofuel Made from Imported Waste Oils

U.S. Senator Roger Marshall of Kansas discusses expected changes to the 45Z tax credit and what they could mean for agriculture and rural America.

WASHINGTON, D.C. (RFD NEWS) — The U.S. Treasury Department is expected to publish updated guidance on the 45Z tax credit on Wednesday. The revised guidance prioritizes North American feedstocks and limits eligibility for imported waste oils such as cooking oil and tallow. It also removes the indirect land use penalty, which the American Soybean Association has previously identified as a significant barrier.

Senator Roger Marshall (R-KS) joined us on Wednesday’s Market Day Report to share his perspective on the new guidance and highlight the potential benefits of the tax credit — not only for farmers and biofuel producers, but also for rural communities.

In his interview with RFD NEWS, Sen. Marshall discussed the details of the revisions and how they reflect priorities he has supported for U.S. agriculture. He also addressed how long the industry has waited for updated guidance, discussed the certainty the changes could bring to producers, and outlined what comes next in the process as the guidance is finalized.

Finally, Marshall shared a message for Kansas cattle producers as NCBA’s CattleCon gets underway in Nashville.
