Future Developments

For the latest information about
developments related to Form 8379 and
its instructions, such as legislation
enacted after they were published, go to
IRS.gov/Form8379.

What’s New
Reporting nonrefundable and refundable credits. A separate breakdown for
nonrefundable and refundable credits was
created. Line 16 is repurposed for
reporting nonrefundable credits. Line 17
will be used for reporting refundable
credits.

Reminder

If both spouses have qualified business
income (QBI), the IRS will generally use
information reported with the jointly filed
Form 1040 or 1040-SR to allocate the QBI
deduction as a percentage of each
spouse’s QBI.

General Instructions
Purpose of Form

Form 8379 is filed by one spouse (the
injured spouse) on a jointly filed tax return
when the joint overpayment was (or is
expected to be) applied (offset) to a
past-due obligation of the other spouse.
By filing Form 8379, the injured spouse
may be able to get back his or her share of
the joint refund.

Which Revision To Use

Use the November 2021 revision of Form
8379 for tax years beginning in 2021 or
later, until a later revision is issued. Use
prior revisions of the form and instructions
for earlier tax years. All revisions are
available at IRS.gov/Form8379.

Are You an
Injured Spouse?

You may be an injured spouse if you file a
joint return and all or part of your portion of
the overpayment was, or is expected to
be, applied (offset) to your spouse's
legally enforceable past-due federal tax,
state income tax, state unemployment
compensation debts, child support, or a
federal nontax debt, such as a student
loan.

Nov 14, 2021

A Notice of Offset for federal tax debts
is issued by the IRS. A Notice of Offset for
past-due state income tax, state
unemployment compensation debt, child
support, or federal nontax debts (such as
a student loan) is issued by the U.S.
Treasury Department's Bureau of the
Fiscal Service.
Visit IRS.gov/TaxTopics/tc203
TIP and Fiscal.Treasury.gov for more
information about refund offsets
and debts.
Complete Part I to determine if you are
an injured spouse.

Innocent Spouse Relief

Don’t file Form 8379 if you are claiming
innocent spouse relief. Instead, file Form
8857. Generally, both spouses are
responsible for paying the full amount of
tax, interest, and penalties due on your
joint return. However, if you qualify for
innocent spouse relief, you may be
relieved of part or all of the joint tax
liability. You may qualify for relief from the
joint tax liability if any of the following
apply.
• There is an understatement of tax
because your spouse omitted income or
claimed false deductions or credits, and
you didn't know or have reason to know of
the understatement.
• There is an understatement of tax and
you are divorced, separated, or no longer
living with your spouse.
• Given all the facts and circumstances, it
wouldn't be fair to hold you liable for the
tax.
See Pub. 971 for more details.

When To File

File Form 8379 when you become aware
that all or part of your share of an
overpayment was, or is expected to be,
applied (offset) against your spouse's
legally enforceable past-due obligations.
You must file Form 8379 for each year you
meet this condition and want your portion
of any offset refunded.
You must file Form 8379 within 3 years
from the due date of the original return
(including extensions) or within 2 years
from the date you paid the tax that was
later offset, whichever is later. Certain
circumstances described in section 6511
may extend this period.

Cat. No. 52888M

How To File

You can file Form 8379 with your joint
return or amended joint return (Form
1040-X), or you can file it afterwards by
itself. File Form 8379 with Form 1040-X
only if you are amending your original
return to claim a joint refund.
If you file Form 8379 with your joint
return, attach it to your return in the order
of the attachment sequence number
(located in the upper right corner of the tax
form). Enter “Injured Spouse” in the upper
left corner of page 1 of the joint return.
If you file Form 8379 separately, please
be sure to attach a copy of all Forms W-2
and W-2G for both spouses, and any
Forms 1099 showing federal income tax
withholding, to Form 8379. The
processing of Form 8379 may be delayed
if these forms are not attached, if the form
is incomplete when filed, or if you attach a
copy of your previously filed joint return.

Time Needed To Process
Form 8379

Generally, if you file Form 8379 with a joint
return on paper, the time needed to
process it is about 14 weeks (11 weeks if
filed electronically). If you file Form 8379
by itself after a joint return has been
processed, the time needed is about 8
weeks. Processing errors can increase the
time needed to process your Form 8379.

Amending Your
Tax Return

If you live in a community property state
that recognizes your marriage, special
rules will apply to the calculation of your
injured spouse refund. Enter the
community property state(s) where, at any
time during the year, you and your spouse
resided and intended to establish a
permanent home. For more information
about the factors used to determine
whether you are subject to community
property laws, see Pub. 555.
In community property states,
overpayments are considered joint
property and are generally applied (offset)
to legally owed past-due obligations of
either spouse. However, there are
exceptions. The IRS will use each state's
rules to determine the amount, if any, that
would be refundable to the injured spouse.
Under state community property laws,
50% of a joint overpayment (except the
earned income credit) is applied to
non-federal tax debts such as child
support, student loans, state
unemployment compensation debts, or
state income tax. However, state laws
differ on the amount of a joint
overpayment that can be applied to a
federal tax debt. The earned income credit
is allocated to each spouse based on
each spouse's earned income.
For more guidance regarding the
amount of an overpayment from a joint
return that the IRS may offset against a
spouse's separate tax liability, see the
revenue ruling for your state next.

If you file an amended joint return (Form
1040-X) to claim an additional refund and
you don't want your portion of the
overpayment to be applied (offset) against
your spouse's legally enforceable
past-due obligation(s), then you will need
to complete and attach another Form 8379
to allocate the additional refund.

Part I
Line 3. Not all debts are subject to a tax
refund offset. To determine if a debt is
owed (other than federal tax), and whether
an offset will occur, contact the Bureau of
the Fiscal Service at 800-304-3107 (for
TTY/TDD help, call 866-297-0517).
Filing Form 8379 when no

TIP past-due obligation exists will
delay your refund.

Line 5a. Community property states are
Arizona, California, Idaho, Louisiana,
Nevada, New Mexico, Texas,
Washington, and Wisconsin.

Line 5b. Check the “No” box on line 5b if
you meet all of the following conditions.
• You have a same-sex spouse whom
you legally married in a jurisdiction that
recognizes same-sex marriages.
• You resided during the tax year in a
community property state that did not
recognize same-sex marriages during the
tax year.

• The state's community property laws
did not apply to you during the tax year.
The special rules discussed earlier
under Line 5a don't apply to you.
Line 9. Refundable credits include the
following.
• American opportunity credit (2009 and
later years).
• Credit for federal tax paid on fuels.
• Refundable prior year minimum tax.
• Health coverage tax credit.
• Premium tax credit (2014 and later
years).
• Recovery rebate credit (2020 and
2021).
• Refundable child tax credit (2021).
• Refundable child and dependent care
tax credit (2021).
• Qualified sick and family leave credits
for certain self-employed individuals.
Any economic impact payments you
received are advance payments of the
recovery rebate credit. See Form 1040 or
1040-SR, line 30.
Any advance payments of the child tax
credit you received are used to figure your
child tax credit. See Schedule 8812 (Form
1040).

Part II
Line 12. If you checked the “Yes” box,
enter the address and read the following
instructions.
• If the address change is permanent,
submit Form 8822, Change of Address,
with Form 8379. If your last return was a
joint return, your spouse must also sign
Form 8822 unless you, the injured spouse,
check the box on line 1 of Form 8822
indicating that you are establishing a
separate residence.
• If the address change is temporary,
don't submit Form 8822. However, the
temporary address change may delay
your injured spouse refund.
Foreign address. Enter the information
in the following order: Number and street,
city, province, county, or state, and
country. Follow the country's practice for
entering the postal code. Do not
abbreviate the country name.

Part III

To properly determine the amount of tax
owed and overpayment due to each
spouse, an allocation must be made as if
each spouse filed a separate tax return
instead of a joint return. So, each spouse
must allocate his or her separate wages,
self-employment income and expenses
(and self-employment tax), and credits
such as education credits, to the spouse
who would have shown the item(s) on his
or her separate return.
Other items that may not clearly belong
to either spouse (for example, a penalty

Instructions for Form 8379 (November 2021)

on early withdrawal of savings from a joint
bank account) would be equally divided.
If you live in a community property
state, follow the instructions below to
allocate your income, expenses, and
credits. The IRS will apply your state's
community property laws based on your
allocation if you checked the “Yes” box on
line 5b.
The IRS will figure the amount of any
refund due the injured spouse.
If a deduction or credit would not be
allowed had you filed a separate return,
use the deduction or credit shown on your
joint return and allocate that amount
between you and your spouse. An
example of a deduction that is generally
not allowed on a separate return is the
student loan interest deduction. Examples
of credits not allowed on a separate return
are the child and dependent care credit
and the American opportunity credit. A
similar rule applies to income and
deductions (such as taxable social
security benefits and the IRA deduction)
that are subject to special limits on a
separate return. Use the income and
deductions shown on your joint return and
allocate them between you and your
spouse.
Line 13a. In column (a), include any
income shown on your joint return from
Form(s) W-2. This income will generally
be reported on Form 1040 or 1040-SR,
line 1.
However, do not include any income
shown on this line that was not from
Form(s) W-2.
In columns (b) and (c), enter only Form
W-2 income on this line. Enter the
separate income that each spouse
earned.
Line 13b. In column (a), include all other
income shown on your joint return. Identify
the type and amount. This income will
generally be reported on Form 1040 or
1040-SR, lines 1–9 (includes Schedule 1
(Form 1040), lines 1–10).
However, do not include any income
shown on this line from Form(s) W-2.
In columns (b) and (c), allocate joint
income, such as interest earned on a joint
bank account, as you determine. Be sure
to allocate all income shown on the joint
return.
Line 14. In column (a), include any
adjustments shown on your joint return.
These adjustments will be reported on
Form 1040 or 1040-SR, line 10 (includes
Schedule 1 (Form 1040), lines 11–26).
In columns (b) and (c), allocate each
adjustment to the spouse who would have
claimed it if a separate return had been
filed. For example, allocate the IRA
deduction to the spouse who owns the

IRA and allocate the student loan interest
deduction to the spouse who is legally
obligated to make the interest payments. If
there are any adjustments that don't
belong exclusively to one spouse, allocate
them as you determine.
Line 15. In column (a), enter the standard
deduction (plus any charitable
contributions allowed if you take the
standard deduction) or itemized
deductions shown on your joint return.
These amounts will be reported on Form
1040 or 1040-SR, line 12c.
If you used the standard deduction.
In columns (b) and (c), include one-half of
your basic standard deduction.
Your basic standard deduction is
generally as follows.

Basic Standard Deduction
2021
2022

$25,100
$25,900

However, if someone could claim you or
your spouse as a dependent, your basic
standard deduction is the amount on
line 4c of the standard deduction
worksheet, found in the Instructions for
Form 1040 (or 1040-SR). If you checked
any boxes for age or blindness on your
joint return, use the following worksheet to
allocate the additional standard deduction
(the difference between the total standard
deduction and the basic standard
deduction).
1. Enter here the total number of
boxes checked for age or
blindness for yourself (the
injured spouse) on your
joint return . . . . . . . . . . .
2. Enter the additional standard
deduction for the year as
shown below . . . . . . . . . .
2021 $1,350
2022 $1,400
3. Multiply line 2 by line 1. Include
this amount on line 15, column
(b) . . . . . . . . . . . . . . . . .
4. Enter here the total number of
boxes checked for age or
blindness for your spouse on
your joint return . . . . . . . .
5. Multiply line 4 by line 2. Include
this amount on line 15, column
(c) . . . . . . . . . . . . . . . . .

Also, in columns (b) and (c), allocate
any charitable contributions reported on
line 12b of the joint return to the spouse
who would have claimed the contributions
if a separate return had been filed. If any
contributions don't belong exclusively to

one spouse, allocate them as you
determine.
If you itemize your deductions. In
columns (b) and (c), include each
spouse's separate deductions, such as
state and local income taxes. Allocate
other deductions as you determine.
Line 16. In column (a), enter any
nonrefundable tax credits shown on your
joint return. These credits are reported on
Form 1040 or 1040-SR, line 19, and in
Part I of Schedule 3 (Form 1040).
In columns (b) and (c), allocate any
nonrefundable child tax credit, credit for
other dependents, child and dependent
care credit, and education credit solely
based on a dependent’s education
expenses to the spouse who would have
claimed the qualifying child (or qualifying
relative) as a dependent if separate
returns had been filed. Allocate any other
credits as you determine.
Line 17. In column (a), include any
refundable tax credits (except the earned
income credit) shown on your joint return.
These credits will be reported on Form
1040 or 1040-SR, lines 28 through 30, and
in Part II of Schedule 3 (Form 1040).
In columns (b) and (c), allocate any
refundable child tax credit, child and
dependent care credit, additional child tax
credit, and education credit solely based
on a dependent’s education expenses to
the spouse who would have claimed the
qualifying child (or qualifying relative) as a
dependent if separate returns had been
filed.
Don't include any earned income credit
here; the IRS will allocate it based on each
spouse's income. Allocate business
credits based on each spouse's interest in
the business. Allocate any other credits as
you determine.
Line 18. In column (a), include any other
taxes shown on your joint return. These
other taxes will be reported on Schedule 2
(Form 1040), line 2, and in Part II of
Schedule 2.
In columns (b) and (c), allocate
self-employment tax to the spouse who
earned the self-employment income.
Allocate the excess advance premium tax
credit repayment and the individual
responsibility payment for healthcare in
any way you choose. Allocate the Net
Investment Income Tax (Form 8960)
consistently with the allocation used for
net investment income on line 13b.
Line 19. In column (a), include any
federal income tax withheld shown on your
joint return. The tax withheld will be
reported on Form 1040 or 1040-SR,
line 25d, and Schedule 3 (Form 1040),
line 11.
In columns (b) and (c), enter federal
income tax withheld from each spouse's

income as shown on Forms W-2, W-2G,
and 1099. Be sure to attach copies of
these forms to your tax return or to Form
8379 if you are filing it by itself. Also,
include on this line any excess social
security or tier 1 railroad retirement
(RRTA) tax withheld and any Additional
Medicare Tax withholding from Form
8959, line 24, attributed to each spouse.

.

Line 20. In column (a), include any
payments shown on your joint return.
These payments will be reported on Form
1040 or 1040-SR, line 26, and Schedule 3
(Form 1040), line 10.
In columns (b) and (c), you can allocate
joint estimated tax payments in any way
you choose as long as both you and your
spouse agree. If you can't agree, the
estimated tax payments will be allocated
according to the following formula:
Each spouse's
separate tax liability
Estimated tax
×
Both separate tax
payments
liabilities

Allocate each spouse's separate
estimated tax payments to the spouse
who made them.
Daytime phone number. Providing your
daytime phone number may help speed

the processing of Form 8379. We may
have questions about items on it. If you
answer our questions over the phone, we
may be able to continue processing Form
8379 without mailing you a letter.

How To Avoid
Common Mistakes

Mistakes may delay your refund or result
in notices being sent to you.
• If you file Form 8379 separately, don't
include a copy of your joint return. This will
prevent delays in processing your
allocation. Make sure to enclose copies of
all Forms W-2 and W-2G for both
spouses, and any Forms 1099 showing
income tax withheld.
• If you file Form 8379 with your joint
return or amended joint return, enter
“Injured Spouse” in the upper left corner of
page 1 of your joint return.
• Items of income, expenses, credits, and
deductions must be allocated to the
spouse who would have entered the item
on his or her separate return.
• Make sure the debt is subject to offset
(for example, a legally enforceable
past-due federal tax, state income tax,
child support, state unemployment
compensation debts, or other federal
nontax debt, such as a student loan).
