A push for US lawmakers to extend various biofuel incentives before the end of the year has met resistance in the Senate.
A growing coalition of biofuel and soybean groups has endorsed extending for one year a $1/USG federal tax credit for blenders of biomass-based diesel, which would otherwise expire after December and be replaced by the Inflation Reduction Act's carbon-intensity-based "45Z" credit. But lawmakers have various other priorities in the final weeks of this legislative session, and a staffer with the Democratic-controlled US Senate Finance Committee confirmed that prospects for a deal to extend biofuel tax credits are slim.
"Republicans have showed very little interest in working with Democrats on much of anything related to tax," said Ryan Carey, chief communications advisor and deputy policy director at the Committee on Finance. "Their focus is primarily on the next Congress, when they're going to attempt to pass an extension of the first Trump tax law on a partisan basis."
Another Senate office acknowledged on background that it is "unlikely" Congress will come to any major tax deal before the end of the year.
Congress has other priorities for its brief lame duck session before president-elect Donald Trump begins his second term, including government funding, the federal debt limit, and a new farm bill. Tax policy could still fit into an end-of-year package, with some less controversial tax provisions and a bipartisan business tax proposal backed by Senate Finance Committee chair Ron Wyden (D-Oregon) still under discussion. But prolonging the biodiesel blenders credit — plus other biofuel credits benefiting sustainable aviation fuel and cellulosic fuels that some groups have also pushed to extend — appears to be a tougher lift.
With Trump in the White House and Republicans set to control both chambers of Congress, Republicans are now preparing major tax policy legislation next year to prolong tax cuts passed during Trump's first term that are set to expire at the end of 2025. Lawmakers are likely to look at repealing some Inflation Reduction Act clean energy subsidies to help offset the cost of that proposal. Republicans on the House tax-writing committee this week requested public input on the 45Z credit specifically, a signal that they are at least open to modifications — and are already looking to tax policy next year.
Biofuel subsidies are seen by analysts and lobbyists as less likely targets for repeal than other Inflation Reduction Act credits, given support for the industry among farm state lawmakers. But the request-for-information this week suggested that Republicans are wary of elements of the current 45Z credit and could support changes that benefit agribusiness. Even biofuel groups generally supportive of the 45Z credit's structure have been frustrated by President Joe Biden's administration, which has yet to issue guidance clarifying how it will calculate the carbon intensities of different fuels and feedstocks.
