PFAS Cleanup Act Proposes 45% US Tax on PFAS Sales

The PFAS Cleanup Act, introduced in the US House of Representatives on 30 April 2026, would amend the Internal Revenue Code to impose a 45% excise tax on sales of perfluoroalkyl and polyfluoroalkyl substances, while establishing a 25% tax credit for qualifying PFAS removal from public water systems. The bill, H.R.8632, was introduced by Representative Linda T. Sánchez and referred to the House Committee on Ways and Means.

PFAS tax proposal targets manufacturers, producers and importers

The bill would apply the excise tax to PFAS sold by manufacturers, producers or importers. It defines PFAS as any man-made chemical with at least one fully fluorinated carbon atom that is manufactured or produced in the US, or entered into the US for consumption, use or warehousing. The proposal also treats internal use as a taxable sale. If a company manufactures, produces or imports PFAS and then uses it itself, the tax would be calculated as if the substance had been sold at fair market value. The provisions would apply to taxable years beginning after 31 December 2026.

PFAS cleanup credit could support public water systems

H.R.8632 would create a PFAS water remediation credit worth 25% of qualified expenditure. Eligible costs would cover removal of PFAS from taxpayer-owned or taxpayer-operated public water systems where contamination exceeds an Environmental Protection Agency maximum contaminant level under the Safe Drinking Water Act. The bill states that PFAS pollution creates major health and social costs, citing estimated annual health impacts as high as US$60 billion and drinking water removal costs of US$7 million to US$30 million per pound of pollution removed.

Compliance implications for the chemicals value chain

Although the PFAS Cleanup Act is only at the introduced stage, it signals continued congressional interest in using tax policy to address PFAS contamination. As of the Congress.gov record provided, the bill had two cosponsors and no related bills or latest summary. Manufacturers, importers, distributors, water utilities, remediation providers and downstream users should monitor the bill’s progress. Key issues include PFAS classification, import documentation, internal-use accounting, supplier declarations and potential exposure to higher material costs if the tax advances. Summary: The PFAS Cleanup Act would place a 45% excise tax on PFAS sales and create a 25% credit for eligible public water remediation. While not yet law, the proposal could affect chemical producers, importers, utilities and downstream sectors that rely on fluorinated substances or manage PFAS contamination risks.
