General Instructions

Purpose of Form

Use Form 6478 to figure your credit for

alcohol used as fuel. This credit consists

of the following:

You may claim or elect not to claim

the alcohol fuel credit at any time within

the 3 years from the due date of your

return (determined without regard to

extensions) on either an original or an

amended return.

Definitions and Special

Rules

Alcohol. Alcohol, for credit purposes,

includes ethanol and methanol but does

not include:

1. Alcohol produced from petroleum,

natural gas, or coal (including peat), or

2. Alcohol of less than 150 proof. In

figuring the proof of any alcohol,

disregard any denaturants (additives that

make the alcohol unfit for human

consumption). The volume of alcohol

includes any denaturant up to 5% of the

volume of the alcohol and denaturant

combined.

However, methanol produced from

methane gas formed in waste disposal

sites is not alcohol produced from

natural gas, and is included for credit

purposes.

1. Uses it as fuel, or

2. Sells it as fuel to another person.

Straight alcohol. The alcohol must not

be a mixture with gasoline, diesel, or

special motor fuel (other than as a

denaturant). The credit is for alcohol that

during the tax year is:

1. Used by the taxpayer as a fuel in a

trade or business, or

2. Is sold by the taxpayer at retail to

another person and put in the fuel tank

of that person’s vehicle.

Qualified ethanol fuel production. This

is ethanol produced by an eligible

small ethanol producer (defined below)

and during the tax year:

1. Is sold by the producer to another

person—

a. For use by the buyer in the buyer’s

trade or business to produce a qualified

mixture (other than casual off-farm

production),

b. For use by the buyer as a fuel in a

trade or business, or

c. Who sells the ethanol at retail to

another person and puts the ethanol in

the retail buyer’s fuel tank; or

2. Is used or sold by the producer for

any purpose described in 1 above.

Diesel fuel. This is any liquid other than

gasoline that can be used as a fuel in a

diesel-powered highway vehicle.

Special motor fuel. This is any liquid

other than gasoline that is suitable for

use or is used in a motor vehicle or

motor boat.

Noncommercial aviation. This is the

use of an aircraft other than in a

business of transporting persons or

property for pay.

Recapture of credit if not used as fuel.

You must pay the tax on each gallon of

the alcohol or the alcohol in the mixture

at the applicable rate that you used to

figure the credit if you claim any alcohol

fuel credit and later you:

1. Separate the alcohol from the

mixture,

2. Use the mixture other than as a fuel,

3. Mix straight alcohol on which the

credit was allowed for the retail sale,

4. Use the straight alcohol other than

as a fuel, or

5. Do not use the fuel for the

purposes described under Qualified

ethanol fuel production above.

Report the tax on Form 720, Quarterly

Federal Excise Tax Return.

Eligible small ethanol producer. This is

a person who, at all times during the tax

year, has a productive capacity for

alcohol of 30 million gallons or less. This

includes alcohol made from petroleum,

natural gas, coal, peat, and alcohol of

less than 150 proof.

The credit is available only to the

producer who blends the mixture. The

producer must use or sell the mixture in

a trade or business and the credit is

available only for the year the mixture is

sold or used. The credit is not allowed

for casual off-farm production of a

qualified mixture.

1. Alcohol mixture credit,

2. Alcohol credit, and

3. Small ethanol producer credit.

Alcohol mixture. The alcohol must be

used to make a qualified mixture. A

qualified mixture combines alcohol with

gasoline, diesel, or special motor fuel.

The producer of the mixture either:

However, no credit is allowed for

alcohol used by the taxpayer as a fuel in

a trade or business if that alcohol was

sold in a retail sale described in 2

above.

Skip lines 1 through 9 if you are

claiming only a credit that was allocated

to you from a flow-through entity (i.e., S

corporation, partnership, estate, or trust).

Specific Instructions

Use lines 1 through 9 to figure any

alcohol fuel credit from your own trade

or business.

Note: We have shown in column (b) the

rate for ethanol only. If you have a credit

for alcohol other than from ethanol, enter

in column (b) the applicable rate shown

in the instructions for lines 2a, 2b, and

7a through 7c.

Line 2a. Enter the number of gallons of

190 proof or greater alcohol and multiply

by the rate.

Line 2. Enter on the appropriate line the

number of gallons sold or used.

Line 1. Enter the number of gallons of

ethanol that meet the conditions listed

above under Qualified ethanol fuel

production. Do not enter more than 15

million gallons. Multiply by the rate of 10

cents per gallon.

If the line 11 credit includes any small

ethanol producer credit (line 1), you

must separately state to each

shareholder, partner (except a partner in

an electing large partnership),

beneficiary, etc., the number of gallons

on which the credit was figured, and the

productive capacity for alcohol that you,

the flow-through entity, have. State the

productive capacity in terms of gallons.

S corporations, partnerships, estates,

and trusts. Figure the total credit on

lines 1 through 11. Then, allocate the

line 11 credit to each shareholder,

partner, and beneficiary in the same way

that income and loss are divided.

Electing large partnerships, include this

credit in “general credits.”

Line 4. Enter the number of gallons of

other fuels that you blended with the

alcohol shown on lines 2a and 2b. Other

fuels include gasoline, diesel, and

special motor fuel.

Line 5b. Enter the number of gallons

included on line 5a that contain less

than 5.7% of 190-proof alcohol or that

are exempt from excise taxes. The fuel

can be exempt because of specific

exemption, credit, or refund provisions

other than the alcohol fuel credit.

Examples of fuels exempt from excise

tax include fuel that is:

● Used on a farm for farming purposes.

● Supplied to military ships or aircraft or

certain commercial ships or aircraft.

● Used in off-highway business use.

For alcohol other than from ethanol,

the rate is 60 cents per gallon.

Line 2b. Enter the number of gallons of

alcohol that is less than 190 proof but at

least 150 proof and multiply by the rate.

For alcohol other than from ethanol,

the rate is 45 cents per gallon.

Section references are to the Internal

Revenue Code.
Line 7. If you sold or used alcohol or an

alcohol mixture as fuel, you may have

been entitled to an exemption, credit,

refund, or a reduced rate of excise tax.

The alcohol fuel credit must be reduced

to take into account any of these

benefits.

Line 7a. Enter under column (a) the

number of gallons of fuel sold for use in

or used in an aircraft in noncommercial

aviation that is alcohol or alcohol

blended with aviation fuel other than

gasoline if you received an excise tax

benefit because the mixture contained at

least 10% alcohol. If the alcohol did not

contain ethanol, the rate under column

(b) is 14 cents.

Lines 7b and 7c. Use these lines for all

other fuels (including gasohol) if you

received an excise tax benefit because

the fuels contained alcohol.

Line 7b. Enter under column (a) the

number of gallons of fuel that is a

mixture containing less than 85%

alcohol.

Line 7c. Enter under column (a) the

number of gallons of special motor fuel

that contain 85% or more alcohol. If the

alcohol did not contain ethanol, the rate

under column (b) is 6.05 cents.

Line 9. Include this amount in income,

under “Other income” on the applicable

line of your income tax return, even if

you cannot use all the credit because of

the tax liability limitations.

Line 10. Enter the amount of credit that

was allocated to you as a shareholder,

partner, or beneficiary.

Line 11. For an estate or trust, the credit

on line 11 is allocated between the

estate or trust and the beneficiaries in

proportion to the income allocable to

each. In the margin to the right of line

11, the estate or trust should enter its

part of the total credit. Label it “1041

PORTION” and use this amount in lines

12 through 21 (or Form 3800) to figure

the credit to claim on Form 1041. Also,

enter and identify the beneficiaries’

share of the credit to the right of line 11,

and attach a schedule to Form 6478

showing how the total credit was

divided.

Line 17. Although you may not owe

alternative minimum tax (AMT), you

generally must still compute the

tentative minimum tax (TMT) to figure

your credit. For a small corporation

exempt from the AMT under section

55(e), enter zero. Otherwise, complete

and attach the applicable AMT form or

schedule. Enter on line 17 the TMT from

the line shown below:

Line 18. See section 38(c)(3) for special

rules that apply to married couples filing

separate returns, controlled corporate

groups, regulated investment

companies, real estate investment

trusts, and estates and trusts.

Line 21. If you cannot use part of the

credit because of the tax liability limit

(line 20 is smaller than line 11), carry it

back 1 year, then forward for 20 years.

See the separate Instructions for Form

3800 for details.

Form 6478 (1999) Page 4

If your credit from a flow-through

entity includes the small ethanol

producer credit, the flow-through entity

must tell you the amount of the small

producer credit included in the

flow-through credit, the number of

gallons for which the entity claimed the

small ethanol producer credit, and the

productive capacity for alcohol. You as a

shareholder, partner, beneficiary, etc.,

are subject to the 15-million-gallon
