Major Biomass Stove Tax Credit Changes in 2021



Legislation is about to pass Congress which creates a NEW tax credit for biomass heaters under Sec. 25(D) of the U.S. tax code.


The Sec. 25(C) tax credit for biomass stoves is only available for qualifying products installed on or before December 31, 2020. After December 31, 2020, the new tax credit eliminates the old 25(C) tax credit. The Sec. 25(C) tax credit may still be claimed on your 2020 tax return for qualifying purchases and installations completed before December 31, 2020.


What is this new tax credit?

  • Effective Dates: The new tax credit under Sec. 25(D) of the U.S. Internal Revenue Code (“IRC” or “tax code”) will come into effect on January 1, 2021 for qualifying purchases and installations completed on or after that date, through December 31, 2023.

  • Credit Amount: Creates a new tax credit of 26 percent of the purchase and installation costs (with no cap or lifetime limit) under Sec. 25D of the U.S. tax code

  • Qualifying Products: Require qualifying products (any biomass-fueled heater) be at least 75 percent efficient per the higher heating value (HHV) of the fuel

  • See EPA’s certified wood heater lists to find qualifying products (anything with an efficiency number of 75 percent or higher)

  • The IRS will likely publish additional guidance on product eligibility in 2021


What happens to the 25(C) tax credit?

  • This legislation eliminates the tax credit for biomass stoves under IRC Sec. 25(C) starting in 2021 and enacts this provision in its place

  • Any product purchased in 2020 that qualifies for the new Sec. 25(D) credit, but isn’t installed until 2021, can be claimed under the Sec. 25(D) credit on a 2021 tax return. Products may be claimed on the tax return year in which the product installation is complete.
