If your company is urgently trying to understand the new Superfund US Federal Excise and Hazardous Substance Tax regulations and the impact on the organization, there is a short window to prepare and comply.

What is Superfund?

After more than 25 years, excise taxes on a specified list of chemicals and imported hazardous substances in the U.S. have been reinstated through the passing of the Infrastructure Investment and Jobs Act signed into law on November 15, 2021.  The excise taxes, effective July 1, 2022, and the complexities around how they are levied pose serious challenges for companies that import, manufacture, produce, sell, or use any of the 42 taxable chemicals, and 150 listed substances, identified in IRS Notice 2021-66

Who is affected by Superfund and what are their challenges?

The newly reinstated excise tax compliance obligations can be expected to create significant challenges across multiple functional areas of a company including Procurement, Finance, Tax, Environmental Regulatory Departments, and Information Technology. Companies have been given a short window to understand their responsibilities, properly manage these new obligations, and understand the impact on their bottom line.

Challenges created by Superfund for business tax and IT professionals

  • Some of the regulations are clearly defined, while other regulations provide a degree of interpretation to the taxpayer (i.e., responsibility and when tax is owed)
  • The way tax is calculated is complex (i.e., volumetric based, threshold lowered from 50% to 20%)
  • Data required for calculation and reporting is extended across disparate systems
  • Determining the method for calculation on imports that imposes the least amount of tax liability
  •  Managing exemptions, credits, and refunds (i.e., qualifying for one or the other) manually are compounded and expensive to maintain
  • Tracking and monitoring changes to the list of qualified substances (i.e., additions/changes to the shifting list of substances) is still under review by the IRS – anticipate the list will evolve
  • Risk of audit and penalties if not followed accordingly (i.e., failure to report accurately to Treasury Department)
  • Impact on cashflow (i.e., biweekly deposits, threshold of minimum $2,500) since remittance is required to occur every 14 days
  • Dissatisfied customers if incorrectly charging tax

As a result, this puts pressure on the ERP systems, purchasing systems, or other existing operational support systems, to deliver accurate, repeatable, predictable, and consistent excise tax determination results. This in turn leads to an increased burden on IT, Finance and Tax, to either keep the tax content up to date, or to reconcile the inaccuracies during the file preparation and remittance process. And finally, this situation is exacerbated by a lack of compliance process automation (i.e., additional human errors through manual workarounds that add to the effort required to fix compliance errors before the return is finally filed).
