Caution: DRAFT—NOT FOR FILING

This is an early release draft of an IRS tax form, instructions, or publication,
which the IRS is providing for your information. Do not file draft forms and do
not rely on draft forms, instructions, and pubs for filing. We incorporate all
significant changes to forms posted with this coversheet. However, unexpected
issues occasionally arise, or legislation is passed—in this case, we will post a
new draft of the form to alert users that changes were made to the previously
posted draft. Thus, there are never any changes to the last posted draft of a
form and the final revision of the form. Forms and instructions are subject to
OMB approval before they can be officially released, so we post drafts of them
until they are approved. Drafts of instructions and pubs usually have some
additional changes before their final release. Early release drafts are at
IRS.gov/DraftForms and remain there after the final release is posted at
IRS.gov/LatestForms. Also see IRS.gov/Forms.
Most forms and publications have a page on IRS.gov: IRS.gov/Form1040 for
Form 1040; IRS.gov/Pub501 for Pub. 501; IRS.gov/W4 for Form W-4; and
IRS.gov/ScheduleA for Schedule A (Form 1040), for example, and similarly for
other forms, pubs, and schedules for Form 1040. When typing in a link, type it
into the address bar of your browser, not a Search box on IRS.gov.
If you wish, you can submit comments to the IRS about draft or final forms,
instructions, or pubs at IRS.gov/FormsComments. Include “NTF” followed by the
form or pub number (for example, “NTF1040”, “NTFW4”, “NTF501, etc.) in the
body of the message to route your message properly. We cannot respond to all
comments due to the high volume we receive and may not be able to consider
many suggestions until the subsequent revision of the product, but we will
review each “NTF” message. If you have comments on reducing paperwork and
respondent (filer) burden, with respect to draft or final forms, please respond to
the relevant information collection through the Federal Register process; for

responsible for paying the full amount of tax, interest, and
penalties due related to 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.

Form 8379 and its instructions, such as legislation
enacted after they were published, go to IRS.gov/
Form8379.

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

See Pub. 971 for more details.

When To File

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 2023 revision of Form 8379 for tax
years beginning in 2023 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.

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.

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.

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.

Go to IRS.gov/TaxTopics/tc203 and

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.

Generally, if you file Form 8379 with a joint return on
paper, the time needed to process it is about 14 weeks

needed is about 8 weeks. Processing errors can increase
the time needed to process your Form 8379. See How To
Avoid Common Mistakes, later.

Where To File

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.

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.

and (c), include one-half of your basic standard deduction.
Your basic standard deduction is generally as follows.

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 their
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 their separate return.

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 for
Dependents, 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).

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 5.

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.

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).

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 in any way you determine. 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.
