PCORI-Fee-Amount
Key Points Based on IRS and Superfund Guidance:
  • The tax applies to imported substances where more than 20% of their weight or value is derived from taxable chemicals.
  • If the importer does not provide accurate chemical composition details, the IRS requires the tax to be calculated using a default percentage of the substance’s value.
  • The tax can be based on the actual chemical components within the substance or the default valuation method when specific chemical data is not available.
  • Importers must maintain proper documentation showing the breakdown of the taxable chemicals used in the substance.
Who Pays This Tax?

The importer of the substance is responsible for reporting and paying this tax each quarter using Form 720. This responsibility cannot be shifted unless contractually agreed.
