In the waning days of the Biden administration, the Treasury Department is dotting the i’s and crossing the t’s on the tax rules that form the heart of the Inflation Reduction Act and its climate strategy. Today, Treasury has released final rules for the Section 48 Investment Tax Credit, which gives project owners (and/or their tax equity partners) 30% back on their investments in clean energy production.
The IRA-amended investment tax credit, plus its sibling production tax credit, are updates and expansion on tax policies that have been in place for decades supporting largely the solar and wind industries. To be clear, today’s announcement does not contain the final rules for the so-called “technology-neutral” clean electricity tax credits established under the IRA, which will supercede the existing investment and production tax credits beginning next year and for which all non-carbon emitting sources of energy can qualify.
But projects that begin construction this year can still qualify for and claim the legacy credits, which were expanded by the Inflation Reduction Act to include things like standalone energy storage. Projects that go into service this year would only be eligible for the legacy credits, while a project that begins construction this year and goes into service next year or later could choose between the legacy credits or the tech neutral credits, but not both.
The proposed rules, released in November of last year, set off a flurry of campaigning and lobbying by the industry, seeking adjustments to their favor. The final regulations largely hew to the earlier release, although they do include clarifications on what precise aspects of an energy system qualify for the credits. Under the final rules, for instance the “upgrading equipment” necessary for “cleaning and conditioning” biogas — i.e. removing other gases to make it a pure gas stream — can qualify for the credit.
Going into the end of the year, the major items left on the Treasury Department’s agenda were the tech neutral tax credits, rules for the advanced manufacturing tax credit, and rules for credits related to the production of clean hydrogen; advanced manufacturing tax credit rules came out in late October. While the Biden Treasury is doing its best to get rules out the door before Donald Trump’s inauguration, the fate of all clean energy tax credits is up in the air as Republicans prepare take power in Washington and start carving up the IRA, whether by “sledgehammer” or by “scalpel.”
