Bill Overview
Analyzed Economic Effects
2 provisions identified: 0 benefits, 1 costs, 1 mixed.
Aviation biofuel credit capped at $120 million
The law caps the total tax benefits a certified aviation biofuel manufacturer can claim at $120 million. The $120 million limit applies across years and cannot be exceeded.
One aviation biofuel plant can get credits
For tax years starting after December 31, 2025, only one in‑state biofuel maker, with most output as aviation fuel, can be certified. To qualify, the business must submit a third‑party feasibility study, a full business plan, signed supplier and buyer letters, and a financing commitment with proof of equity. The law defines aviation biofuel as biofuel used as aviation fuel. It also requires that at least 80% of the wood feedstock be sourced in Wisconsin, measured over five years. If a certified aviation biofuel business operates in a designated area, that designation can last up to 20 years.
