Sec. 48.4041-11  Tax-free sales of fuel for use in noncommercial 
aviation only if sellers and certain purchasers are registered.

    (a) In general. Any sale of liquid fuel for delivery into a fuel 
supply tank of an aircraft is presumed to be subject to tax under 
section 4041(c), unless both the seller and purchaser of the liquid fuel 
are registered as provided in paragraph (b) of this section or are 
within one of he exceptions provided in paragraph (c) of this section.
    (b) Form of registration. Except as provided in paragraph (c) of 
this section (relating to exceptions for State and local governments, 
for fuel purchased from customs bonded warehouses or continuous customs 
custody, and for fuel purchased for use in certain aircraft of the 
United States or of any foreign nation), tax-free sales under section 
4041(c) may be made only if both the seller and the purchaser have 
registered as required by section 4041(i) and this paragraph (b). If 
fuel is purchased tax paid for use in noncommercial aviation but is used 
for a nontaxable purpose, see section 6427(a) for provisions relating to 
refunds or credits of tax for tax-paid fuels not used for the purpose 
for which sold. Any person desiring to be registered in order to sell or 
purchase fuel free of the tax imposed by section 4041(c) must, before 
making any tax-free sale or purchase, file Form 637A, in duplicate. Form 
637A must be filed with the District Director of Internal Revenue for 
the district in which the principal place of business of the applicant 
is located (or if the applicant has no principal place of business in 
the United States, with the Director of International Operations, 
Internal Revenue Service, Washington, DC 20224). The person who receives 
a validated Certificate of Registry (Validated Form 637A) is considered 
to be registered for purposes of selling or purchasing fuel tax free as 
provided in this section.
    (c) Transactions excepted from registration. (1) A State or local 
government purchasing fuel delivered into a fuel supply tank of an 
aircraft it operates for its exclusive use may, but is not required to, 
register as provided in this section.
    (2) Any purchaser of aircraft fuel who purchases fuel from any 
customs bonded warehouse or from continuous customs custody elsewhere 
than in a bonded warehouse is not required to register to purchase 
aircraft fuel from these sources tax free.
    (3) Any purchaser of fuel for use in an aircraft which is owned by 
the United States or any foreign country and constitutes a part of the 
armed forces thereof is not required to register to purchase aircraft 
fuel tax free.
    (4) The exceptions from registration in paragraphs (c) (1), (2), and 
(3) of this section do not relieve purchasers from the requirement of 
furnishing an exemption certificate as required by paragraph (d) of this 
section.
    (d) Evidence of tax-free sale. (1) To establish the right of a 
purchaser to purchase fuel delivered into the fuel supply tank of an 
aircraft tax free, the seller must obtain from the purchaser and retain 
in its possession a certificate, properly executed and signed by or on 
behalf of the purchaser, containing the following information:
    (i) Date of purchase,
    (ii) The purchaser's registration number (or the exception from 
registration which is relied upon), and

[[Page 64]]

    (iii) A brief statement of the intended tax-free use of the fuel 
(for example, by an airline in the business of transporting persons or 
property for hire).
    (2) The following form of certificate, which must be adhered to in 
substance, is acceptable for the purposes of this paragraph.

(Date) ----------, 19----

(Brief statement of tax-free use)
    The undersigned understands that if the fuel is used otherwise than 
as stated above and for a purpose taxable under section 4041 of the 
Internal Revenue Code, the undersigned will be liable for the tax upon 
such use, and that the undersigned must be prepared to establish by 
satisfactory evidence the purpose for which the fuel purchased under 
this certificate was used.
    The undersigned also understands that the fraudulent use of this 
certificate to secure exemption will subject the undersigned and all 
others making fraudulent use to a penalty equivalent to the amount of 
tax due on the sale of the fuel and, upon conviction, to a fine of not 
more than $10,000, or to imprisonment for not more than 5 years, or 
both, together with the costs of prosecution.

    (3) Except as provided in paragraph (d)(4) of this section, a 
separate exemption certificate must be furnished for each sale of fuel 
delivered into a fuel supply tank of an aircraft. If a portion of the 
fuel is intended to be used for a nontaxable purpose, the entire amount 
of the fuel may be sold tax free. Exemption certificates and proper 
supporting records such as invoices, orders, etc., relative to tax-free 
sales must be readily accessible for inspection by internal revenue 
officers and retained as provided in section 6001 of the Code and the 
regulations thereunder.
    (4) If the purchaser of fuel to be used in an aircraft has 
reasonable grounds to believe that 90 percent or more of the total of 
the fuel to be purchased by it during a specified period not to exceed 
12 calendar quarters will be used in a tax-free use, it may furnish each 
of its suppliers an exemption certificate covering all purchases for the 
specified period. The certificate shall be substantially in the same 
form as the certificate in paragraph (d)(2) of this section, except that 
in place of the date the purchaser shall specify the period covered by 
the certificate, and the purchaser shall give a brief explanation of its 
grounds for belief that 90 percent or more of its total fuel will be 
used in a tax-free use.
    (5) The presumption under section 4041(i) that any liquid delivered 
into a fuel supply tank of an aircraft is taxable places the duty on the 
seller of the liquid fuel to use reasonable diligence to satisfy itself 
that a tax-free sale of fuel to the purchaser is allowed by law. In the 
absence of circumstances surrounding a sale that would raise a question 
as to whether a tax-free sale is allowable, the requirement of 
reasonable diligence is satisfied if the seller receives and retains the 
required certificate evidencing the right of the purchaser to buy the 
fuel tax free. However, if the circumstances are such as to indicate the 
seller has failed to use reasonable diligence, it is not relieved of 
liability for the tax imposed by section 4041(c). In addition, if the 
seller fails to obtain and retain the evidence of tax-free sales as 
required by this paragraph (d), it is not relieved of liability for the 
tax imposed by section 4041(c).
