In this transaction, the fuel is transferred from the delivering party, who holds the inventory position for the taxable fuel at the terminal, as reflected in the terminal operator's records. This type of exchange involves the movement of taxable fuel between parties without a sale taking place.

To calculate tax for a taxable chemical (IRS 54):

  • Find the tax rate for the chemical from the IRS.
  • Determine the number of tons of the chemical.

Remember, these taxes are reported on an annual basis for the second quarter.

The Superfund chemical excise taxes are reported on Form 6627, specifically in Part 1: Environmental Taxes. This form is then attached to Form 720, the Quarterly Federal Excise Tax Return, for filing with the IRS.

For taxable chemicals, the manufacturer, producer, or importer is responsible for reporting and paying the tax to the IRS. For taxable substances, the importer is responsible for reporting and paying the tax to the IRS.



A taxable substance is any substance that, at the time of sale or use by the importer of the substance, is listed as a taxable substance. (ie. The importer of substances who sells or uses those substances.)

151 substances are listed as taxable substances. Among the 151 substances, the IRS has directly determined tax rates for 120 substances.

For 31 substances (*) Tax rate per ton to be determined at a later date. Effective date is 7/1/2022. Tax amount can be calculated using conversion factor or entry value for those 31 substances.

To pay Superfund chemical excise taxes using EFTPS:

  • If paying only Superfund chemical excise tax (IRS No. 54 or 17):
    • Do not break the total payment into subcategories.
    • Simply make a single payment for the total amount.
  • If paying Superfund chemical excise tax along with other excise taxes:
    • Make two separate payments in EFTPS:
      • One payment for the Superfund chemical excise tax.
      • Another payment for any other excise taxes listed in the subcategories in EFTPS.

There are two separate Superfund chemical excise taxes:

  • A tax on the sale or use of taxable chemicals (Tax on Chemicals (Other Than Ozone-Depleting Chemicals), IRS No. 54)
  • A tax on the sale or use of imported taxable substances (Tax on Imported Chemical Substances, IRS No. 17)

There are two ways by which you can file your return:

  • E- Filing is Electronically submitting Federal Excise Tax Returns to the IRS through online.
  • Paper Filing is sending the Federal Excise Tax Returns to the IRS through the mail.

There are three scenarios to calculate tax amount for the imported taxable substance:

  1. First scenario: IRS tax of the substance is known

    Tax rate for the imported chemical substance (120 substances) is known. Hence, tax amount is calculated by multiplying the number of tons with the tax rate of the chosen taxable substance.

  2. Second scenario: Entry value of the substance is known

    Appraised entry value of the imported chemical substance (31 substances) is known. Hence, tax amount is calculated by multiplying the appraised entry value with the default tax rate of 0.1.

  3. Third scenario: Conversion factor of the taxable chemical is known

    An imported taxable substance is made up of two taxable chemicals. If the conversion factor of each taxable chemical is known, then the tax amount is calculated by multiplying the number of tons and the conversion factor with the tax rate of each taxable chemical.

If you import a gas-guzzling automobile, you may be eligible to make a one-time filing of Form 720 and Form 6197 if you meet both of the following conditions:

  1. You do not import gas-guzzling automobiles in the course of your trade or business.
  2. You are not required to file Form 720 reporting excise taxes for the calendar quarter, except for a one-time filing.

Example:

In August 2006, H, an individual, imported a car. The car has a fuel economy rating of 15 mpg, so H is liable for the gas guzzler tax of $4,500 (Form 6197, line 9). H meets the two conditions for a one-time filing, that is:

  1. H does not import gas-guzzling automobiles in the course of his trade or business, and
  2. H is not otherwise required to file Form 720.

He must file Forms 720 and 6197 for the third calendar quarter of 2006. H does not have to deposit the gas guzzler tax of $4,500 but instead pays with the return. H checks the one-time filing box on Form 720.
