Taxpayer Certainty and Disaster Tax Relief Act of 2020: Spotlight on the Proposed Extensions of Certain Alternative Energy Tax Credits

On Dec. 21, 2020, Congress passed a COVID-19 relief bill (the Consolidated Appropriations Act, 2021) including the Taxpayer Certainty and Disaster Tax Relief Act of 2020, which would provide much-anticipated extensions to critical alternative energy tax credits (including those for wind and solar projects) certain of which were on the brink of expiring. Generally, the bill provides for one- to two-year extensions depending on the energy generated from the project and modifies existing tax credit phasedown schedules provided in the Internal Revenue Code (the Code).

In particular, a noteworthy feature of the bill is that offshore wind projects which start construction through 2025 are eligible for a 30% investment tax credit (ITC) (without a phasedown). Additionally, sustaining the solar ITC at the 26% level for an additional two years is a valuable amendment proposed in the bill. Below is a summary of these and other potential extensions and a new tax credit for waste energy recovery property.

On or before Dec. 31, 2023

10% ITC

 Other Extensions

  • The 12-year PTC provided in Code Section 45Q for carbon oxide sequestration would similarly benefit from a two-year extension to begin construction (to the end of 2025).

  • Closed-loop biomass, open-loop biomass, geothermal, landfill gas, trash, hydropower, and marine and hydrokinetic renewable energy facilities each would receive one-year extensions for beginning construction deadlines (to the end of 2021) for the applicable PTC and, alternatively, the ITC.

Concluding Comments

  • The above extensions relate to when construction must begin to qualify for the applicable tax credits and tax credit amounts, but do not affect the rules for qualification for the credits (for instance, the four-year continuous construction safe harbor still applies where applicable).

  • While the COVID-19 relief bill would provide welcome benefits to various types of renewable energy property (including wind and solar), it does not provide the much-discussed tax credits for standalone energy storage.

  • At the time of the writing of this Alert, President Donald Trump was expected to sign this legislation.
