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’re filing Form 720-X separately, send Form 720-X to:
Department of the Treasury
Internal Revenue Service
Cincinnati, OH 45999-0009
Otherwise, attach Form 720-X to your next Form 720.

(PDS) designated by the IRS to meet the “timely mailing as timely filing”
rule for tax returns. Go to www.irs.gov/PDS for the current list of
designated services. The PDS can tell you how to get written proof of
the mailing date. For the IRS mailing address to use if you’re using PDS,
go to www.irs.gov/PDSstreetAddresses.

!

CAUTION

Private delivery services can’t deliver items to P.O. boxes. You
must use the U.S. Postal Service to mail any item to an IRS P.O.
box address.

Specific Instructions
P.O. Box. If the post office doesn’t deliver mail to the street address and you
have a P.O. Box, show the box number instead of the street address.
Foreign address. Don’t abbreviate the country name. Follow the country’s
practice for entering the postal code and the name of the province, country,
or state.

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’re amending. If
you’re amending more than one quarter, make sure each quarter is clearly
identified. Enter the date in the MMDDYYYY format. For example, if you’re
adjusting the first quarter return for 2020, enter “03312020.”
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.
Section 6426 credits. You must use line 2 to report any adjustment to
section 6426 credits, if (a) you’re 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 weren’t registered. Section 6426 credits include the 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 also complete line 6.

with your name and EIN as needed.
Adjustments on line 1. For each adjustment, you must include a detailed

720 (Rev. January 2020). For each adjustment you must attach a detailed
