CAUTION
You must include in gross income (income tax return) any
overpayment from line 4 of Form 720X if you took a deduction on
the income tax return that included the amount of the taxes and
that deduction reduced the income tax liability. See Pub. 510,
Excise Taxes, for more information.
When To File
Generally, adjustments that decrease your tax liability for a prior quarter
must be made within 3 years from the time the return was filed or 2 years
from the time the tax was paid, whichever is later.
Where To File
If you are filing Form 720X separately, send Form 720X to:
Department of the Treasury
Internal Revenue Service
Cincinnati, OH 45999-0009
Otherwise, attach Form 720X to your next Form 720.
Specific Instructions
Line 1
Report each adjustment separately on line 1. You can use line 6 for your
explanation or you can attach additional sheets with your name and EIN as
needed.
Column (a). Enter the quarter ending date of the Form 720 you are
amending. If you are amending more than one quarter, make sure each
quarter is clearly identified. Enter the date in the MMDDYYYY format. For
example, if you are adjusting the first quarter return for 2013, enter
“03312013.”
Column (d). Enter the tax amount for the IRS No. entered in column (b) as
originally reported on Form 720 or as later adjusted by you or the IRS.
Column (e). Enter the adjusted tax liability that should have been reported
for the IRS No. in column (b).
Column (f). If column (e) is greater than column (d), subtract column (d) from
column (e). This is an increase. If column (d) is greater than column (e),
subtract column (e) from column (d). This is a decrease. Show the decrease
in parentheses.
Line 2
Section 4051(d) tire credit. You must use line 2 to report any adjustment to
the section 4051(d) tire credit for a prior quarter. For example, if you report
an additional taxable vehicle on line 1 for IRS No. 33, the applicable tire
credit is reported on line 2. Enter CRN 366 in column 2(b). See the
Instructions for Form 720 for more information on the tire credit.
Section 6426 credits. You must use line 2 to report any adjustment to
section 6426 credits, if (a) you are reporting a change to certain taxable fuel
liability (section 4081 liability in the case of mixtures or section 4041 liability
in the case of alternative fuel) on line 1, or (b) you were unable to claim the
credits against the section 4041 or 4081 liability on a prior Form 720 because
you were not registered. Section 6426 credits include the alcohol fuel mixture
credit (for mixtures produced, and sold, used, or removed, on or before
December 31, 2011), biodiesel or renewable diesel mixture credit, alternative
fuel credit, and alternative fuel mixture credit. Use a separate line for each
adjustment. Enter the CRN from the table below in column 2(b). You must
