Section 80201 of the Infrastructure Investment and Jobs Act of 2021, Public Law 117-58, reinstates the long-expired federal excise taxes that are imposed on specified chemical substances used in common industrial applications pursuant to Sections 4661 and 4671 of the Internal Revenue Code. The effective date of this reinstatement is July 1, 2022, and these taxes expire on December 31, 2031. The Act “decoupled” these reinstated chemical taxes from the now-expired Superfund petroleum excise tax that also funded the Superfund Hazardous Substance Response Trust Fund, which was created when Superfund (formally known as the Comprehensive Environmental Response Compensation and Liability Act, or CERCLA) was enacted in 1980. The Secretary of the Treasury was directed to publish an initial list of taxable chemicals by January 1, 2022, and this initial list was set forth in IRS Notice 2021-66. The list contains not only the 50 taxable chemical substances listed in Section 4672 (a)(3) of the Internal Revenue Code but also the 101 taxable chemicals listed in this Notice. In addition, Section 80201 of the Act also modified the existing tax rates by raising them.
