PART 48_MANUFACTURERS AND RETAILERS EXCISE TAXES--Table of Contents
 
 Subpart H_Motor Vehicles, Tires, Tubes, Tread Rubber, and Taxable Fuel
 
Sec. 48.4081-6  Gasoline; gasohol.

    (a) Overview. This section provides rules for determining the 
applicability of reduced rates of tax on a removal or entry of gasohol 
or of gasoline used to produce gasohol. Rules are also provided for the 
imposition of tax on the separation of gasoline from gasohol and the 
failure to use gasoline that has been taxed at a reduced rate to produce 
gasohol.
    (b) Explanation of terms--(1) Alcohol--(i) In general; source of the 
alcohol. Except as provided in paragraph (b)(1)(ii) of this section, 
alcohol means any alcohol that is not a derivative product of petroleum, 
natural gas, or coal (including peat). Thus, the term includes methanol 
and ethanol that are not derived from petroleum, natural gas, or coal 
(including peat). The term also includes alcohol produced either within 
or outside the United States.
    (ii) Proof and denaturants. Alcohol does not include alcohol with a 
proof of less than 190 degrees (determined without regard to added 
denaturants). If the alcohol added to a fuel/alcohol mixture (the added 
alcohol) includes impurities or denaturants, the volume of alcohol in 
the mixture is determined under the following rules:
    (A) The volume of alcohol in the mixture includes the volume of any 
impurities (other than added denaturants and any fuel with which the 
alcohol is mixed) that reduce the purity of the added alcohol to not 
less than 190 proof (determined without regard to added denaturants).
    (B) The volume of alcohol in the mixture includes the volume of any 
approved denaturants that reduce the purity of the added alcohol, but 
only to the extent that the volume of the approved denaturants does not 
exceed five percent of the volume of the added alcohol (including the 
approved denaturants). If the volume of the approved denaturants exceeds 
five percent of the volume of the added alcohol, the excess over five 
percent is considered part of the nonalcohol content of the mixture.
    (C) For purposes of this paragraph (b)(1)(ii), approved denaturants 
are any denaturants (including gasoline and nonalcohol fuel denaturants) 
that reduce the purity of the added alcohol and are added to such 
alcohol under a formula approved by the Secretary.
    (iii) Products derived from alcohol. If alcohol described in 
paragraphs (b)(1)(i) and (ii) of this section has been chemically 
transformed in producing another product (that is, the alcohol is no 
longer present as a separate chemical in the other product) and there is 
no significant loss in the energy content of the alcohol, any mixture 
containing the product includes the volume of alcohol used to produce 
the product. Thus, for example, a mixture of gasoline and ethyl tertiary 
butyl ether (ETBE), or of gasoline and methyl tertiary butyl ether 
(MTBE), includes any alcohol described in paragraphs (b)(1)(i)

[[Page 118]]

and (ii) of this section that is used to produce the ETBE or MTBE, 
respectively, in a chemical reaction in which there is no significant 
loss in the energy content of the alcohol.
    (2) Gasohol--(i) In general--(A) Gasohol is a mixture of gasoline 
and alcohol that is 10 percent gasohol, 7.7 percent gasohol, or 5.7 
percent gasohol. The determination of whether a particular mixture is 10 
percent gasohol, 7.7 percent gasohol, or 5.7 percent gasohol is made on 
a batch-by-batch basis. A batch of gasohol is a discrete mixture of 
gasoline and alcohol.
    (B) If a particular mixture is produced within the bulk transfer/
terminal system (for example, at a refinery), the determination of 
whether the mixture is gasohol is made at the time of the taxable 
removal or entry of the mixture.
    (C) If a particular mixture is produced outside of the bulk 
transfer/terminal system (for example, by splash blending after the 
gasoline has been removed from the terminal at the rack), the 
determination of whether the mixture is gasohol is made immediately 
after the mixture is produced. In such a case, the contents of the batch 
typically correspond to a gasoline meter delivery ticket and an alcohol 
meter delivery ticket, each of which shows the number of gallons of 
liquid delivered into the mixture. The volume of each component in a 
batch (without adjustment for temperature) ordinarily is determined by 
the number of metered gallons shown on the delivery tickets for the 
gasoline and alcohol delivered. However, if metered gallons of gasoline 
and alcohol are added to a tank already containing more than a minor 
amount of liquid, the determination of whether a batch satisfies the 
alcohol-content requirement will be made by taking into account the 
amount of alcohol and non-alcohol fuel contained in the liquid already 
in the tank. Ordinarily, any amount in excess of 0.5 percent of the 
capacity of the tank will not be considered minor.
    (ii) 10 percent gasohol--(A) In general. A batch of gasoline/alcohol 
mixture is 10 percent gasohol if it contains at least 9.8 percent 
alcohol by volume, without rounding.
    (B) Batches containing less than 10 percent but at least 9.8 percent 
alcohol. If a batch of mixture contains less than 10 percent alcohol but 
at least 9.8 percent alcohol, without rounding, only a portion of the 
batch is considered to be 10 percent gasohol. That portion equals the 
number of gallons of alcohol in the batch multiplied by 10. Any 
remaining liquid in the mixture is excess liquid.
    (iii) 7.7 percent gasohol--(A) In general. A batch of gasoline/
alcohol mixture is 7.7 percent gasohol if it contains less than 9.8 
percent alcohol but at least 7.55 percent alcohol by volume, without 
rounding.
    (B) Batches containing less than 7.7 percent but at least 7.55 
percent alcohol. If a batch of mixture contains less than 7.7 percent 
alcohol but at least 7.55 percent alcohol, without rounding, only a 
portion of the batch is considered to be 7.7 percent gasohol. That 
portion equals the number of gallons of alcohol in the batch multiplied 
by 12.987. Any remaining liquid in the mixture is excess liquid.
    (iv) 5.7 percent gasohol--(A) In general. A batch of gasoline/
alcohol mixture is 5.7 percent gasohol if it contains less than 7.55 
percent alcohol but at least 5.59 percent alcohol by volume, without 
rounding.
    (B) Batches containing less than 5.7 percent but at least 5.59 
percent alcohol. If a batch of mixture contains less than 5.7 percent 
alcohol but at least 5.59 percent alcohol, without rounding, only a 
portion of the batch is considered to be 5.7 percent gasohol. That 
portion equals the number of gallons of alcohol in the batch multiplied 
by 17.544. Any remaining liquid in the mixture is excess liquid.
    (v) Tax on excess liquid. If tax was imposed on the excess liquid in 
any gasohol at the gasohol production tax rate (as defined in paragraph 
(e)(1) of this section), the excess liquid in the batch is considered to 
be gasoline with respect to which there is a failure to blend into 
gasohol for purposes of paragraph (f) of this section. If tax was 
imposed on the excess liquid at the rate of tax described in section 
4081(a), a credit or refund under section 6427(f) is not allowed with 
respect to the excess liquid.
    (vi) Examples. The following examples illustrate this paragraph 
(b)(2). In

[[Page 119]]

these examples, a gasohol blender creates a gasoline/alcohol mixture by 
pumping a specified amount of gasoline into an empty tank and then 
adding a specified amount of alcohol.

    Example 1. Mixtures containing exactly 10 percent alcohol. The 
applicable delivery tickets show that the mixture is made with 7200 
metered gallons of gasoline and 800 metered gallons of alcohol. 
Accordingly, the mixture contains 10 percent alcohol (as determined 
based on the delivery tickets provided to the blender) and qualifies as 
10 percent gasohol.
    Example 2. Mixtures containing less than 10 percent alcohol but at 
least 9.8 percent alcohol. The applicable delivery tickets show that the 
mixture is made with 7205 metered gallons of gasoline and 795 metered 
gallons of alcohol. Because the mixture contains less than 10 percent 
alcohol, but more than 9.8 percent alcohol (as determined based on the 
delivery tickets provided to the blender), 7950 gallons of the mixture 
qualify as 10 percent gasohol. If tax was imposed on the gasoline in the 
mixture at the gasohol production rate applicable to 10 percent gasohol, 
the remaining 50 gallons of the mixture (the excess liquid) are treated 
as gasoline with respect to which there was a failure to blend into 
gasohol for purposes of paragraph (f) of this section. If tax was 
imposed on the gasoline in the mixture at the rate of tax described in 
section 4081(a), a credit or refund under section 6427(f) is allowed 
only with respect to 7155 gallons of gasoline.
    Example 3. Mixtures containing less than 5.59 percent alcohol. The 
applicable delivery tickets show that the mixture is made with 7568 
metered gallons of gasoline and 436 metered gallons of alcohol. Because 
the mixture contains only 5.45 percent alcohol (as determined based on 
the delivery tickets provided to the blender), the mixture does not 
qualify as gasohol.

    (3) Gasohol blender. Gasohol blender means any person that regularly 
produces gasohol outside of the bulk transfer/terminal system for sale 
or use in its trade or business.
    (4) Registered gasohol blender. Registered gasohol blender means a 
person that is registered under section 4101 as a gasohol blender.
    (c) Rate of tax on gasoline removed or entered for gasohol 
production--(1) In general. The rate of tax imposed on gasoline under 
Sec. 48.4081-2(b) (relating to tax imposed at the terminal rack), Sec. 
48.4081-3(b)(1) (relating to tax imposed at the refinery), or Sec. 
48.4081-3(c)(1) (relating to tax imposed on entries) is the gasohol 
production tax rate if--
    (i) The person liable for tax under Sec. 48.4081-2(c)(1) (the 
position holder), Sec. 48.4081-3(b)(3) (the refiner), or Sec. 48.4081-
3(c)(2) (the enterer) is a taxable fuel registrant and a registered 
gasohol blender, and such person produces gasohol with the gasoline 
within 24 hours after removing or entering the gasoline; or
    (ii) The gasoline is sold in connection with the removal or entry, 
the person liable for tax under Sec. 48.4081-2(c)(1) (the position 
holder), Sec. 48.4081-3(b)(3) (the refiner), or Sec. 48.4081-3(c)(2) 
(the enterer) is a taxable fuel registrant and the person, at the time 
of the sale,--
    (A) Has an unexpired certificate (as described in paragraph (c)(2) 
of this section) from the buyer; and
    (B) Has no reason to believe that any information in the certificate 
is false.
    (2) Certificate--(i) In general. The certificate referred to in 
paragraph (c)(1)(ii)(A) of this section is a statement that is to be 
provided by a registered gasohol blender that is signed under penalties 
of perjury by a person with authority to bind the registered gasohol 
blender, is in substantially the same form as the model certificate 
provided in paragraph (c)(2)(ii) of this section, and contains all 
information necessary to complete such model certificate. A new 
certificate must be given if any information in the current certificate 
changes. The certificate may be included as part of any business records 
normally used to document a sale. The certificate expires on the 
earliest of the following dates:
    (A) The date one year after the effective date of the certificate 
(which may be no earlier than the date it is signed).
    (B) The date the registered gasohol blender provides a new 
certificate to the seller.
    (C) The date the seller is notified by the Internal Revenue Service 
or the gasohol blender that the gasohol blender's registration has been 
revoked or suspended.
    (ii) Model certificate.

    (iii) Use of Form 637 or letter of registration as a gasohol 
blender's certificate prohibited. A copy of the certificate of registry 
(Form 637) or letter of registration issued to a gasohol blender by the 
Internal Revenue Service is not a gasohol blender's certificate 
described in paragraph (c)(2)(ii) of this section.
    (d) Rate of tax on gasohol removed or entered. The rate of tax 
imposed on removals or entries of any gasohol under Sec. Sec. 48.4081-
2(b), 48.4081-3(b)(1), and 48.4081-3(c)(1) is the gasohol tax rate. The 
rate of tax imposed on removals and entries of excess liquid described 
in paragraph (b)(2) of this section is the rate of tax applicable to 
gasoline under section 4081(a).
    (e) Tax rates--(1) Gasohol production tax rate. The gasohol 
production tax rate is the applicable rate of tax determined under 
section 4081(c)(2)(A).
    (2) Gasohol tax rate. The gasohol tax rate is the applicable alcohol 
mixture rate determined under section 4081(c)(4)(A).
    (f) Later separation and failure to blend--(1) Later separation--(i) 
Imposition of tax. A tax is imposed on the removal or sale of gasoline 
separated from gasohol with respect to which tax was imposed at a rate 
described in paragraph (e) of this section or with respect to which a 
credit or payment was allowed or made by reason of section 6427(f)(1).
    (ii) Liability for tax. The person that owns the gasohol at the time 
gasoline is separated from the gasohol is liable for the tax imposed 
under paragraph (f)(1)(i) of this section.
    (iii) Rate of tax. The rate of tax imposed under paragraph (f)(1)(i) 
of this section is the difference between the rate of tax applicable to 
gasoline not described in this section and the applicable gasohol 
production tax rate.
    (2) Failure to blend--(i) Imposition of tax. Tax is imposed on the 
entry, removal, or sale of gasoline (including excess liquid described 
in paragraph (b)(2) of this section) with respect to which tax was 
imposed at a gasohol production tax rate if--
    (A) The gasoline was not blended into gasohol; or

[[Page 121]]

    (B) The gasoline was blended into gasohol but the gasohol production 
tax rate applicable to the type of gasohol produced is greater than the 
rate of tax originally imposed on the gasoline.
    (ii) Liability for tax. (A) In the case of gasoline with respect to 
which tax was imposed at the gasohol production tax rate under paragraph 
(c)(1)(i) of this section, the person liable for the tax imposed by 
paragraph (f)(2)(i) of this section is the person that was liable for 
tax on the entry or removal.
    (B) In the case of gasoline with respect to which tax was imposed at 
the gasohol production tax rate under paragraph (c)(1)(ii) of this 
section, the person that bought the gasoline in connection with the 
entry or removal is liable for the tax imposed under paragraph (f)(2)(i) 
of this section.
    (iii) Rate of tax. The rate of tax imposed on gasoline described in 
paragraph (f)(2)(i)(A) of this section is the difference between the 
rate of tax applicable to gasoline not described in this section and the 
rate of tax previously imposed on the gasoline. The rate of tax imposed 
on gasoline described in paragraph (f)(2)(i)(B) of this section is the 
difference between the gasohol production tax rate applicable to the 
type of gasohol produced and the rate of tax previously imposed on the 
gasoline.
    (iv) Example. The following example illustrates this paragraph 
(f)(2):

    Example. (i) A registered gasohol blender bought gasoline in 
connection with a removal described in paragraph (c)(1)(ii) of this 
section. Based on the blender's certification (described in paragraph 
(c)(2) of this section) that the blender would produce 10 percent 
gasohol with the gasoline, tax at the gasohol production tax rate 
applicable to 10 percent gasohol was imposed on the removal.
    (ii) The blender then produced a mixture by splash blending in a 
tank holding approximately 8000 gallons of mixture. The applicable 
delivery tickets show that the mixture was blended by first pumping 7220 
metered gallons of gasoline into the empty tank, and then pumping 780 
metered gallons of alcohol into the tank. Because the mixture contains 
9.75 percent alcohol (as determined based on the delivery tickets 
provided to the blender) the entire mixture qualifies as 7.7 percent 
gasohol, rather than 10 percent gasohol.
    (iii) Because the 7220 gallons of gasoline were taxed at the gasohol 
production tax rate applicable to 10 percent gasohol but the gasoline 
was blended into 7.7 percent gasohol, a failure to blend has occurred 
with respect to the gasoline. As the person that bought the gasoline in 
connection with the taxable removal, the blender is liable for the tax 
imposed under paragraph (f)(2)(i) of this section. The amount of tax 
imposed is the difference between--

    (A) 7220 gallons times the gasohol production tax rate applicable to 
7.7 percent gasohol; and

    (B) 7220 gallons times the gasohol production tax rate applicable to 
10 percent gasohol.

    (iv) Because the gasohol does not contain exactly 7.7 percent 
alcohol, the benefit of the gasohol production tax rate with respect to 
the alcohol is less than the amount of the alcohol mixture credit under 
section 40(b) (determined before the application of section 40(c)). 
Accordingly, the blender may be entitled to claim an alcohol mixture 
credit for the alcohol used in the gasohol. Under section 40(c), 
however, the amount of the alcohol mixture credit must be reduced to 
take into account the benefit provided with respect to the alcohol by 
the gasohol production tax rate.

    (g) Effective date. This section is effective August 7, 1995.
