Injured Spouse Relief: Getting Your Share of a Joint Refund Back With Form 8379

You filed a joint return expecting a refund. Instead you got a notice saying the refund went to pay your spouse's back child support, a defaulted student loan, or a tax debt from before you were married. You did not owe any of it. Part of that refund came from your paycheck.

That is the situation injured spouse relief was built for. It is one of the most straightforward forms of spousal tax relief, and it is also one of the most often confused with something else.

Why the refund was taken

Internal Revenue Code section 6402 lets the IRS apply an overpayment to the taxpayer's other liabilities before refunding it. Section 6402(a) covers federal tax liabilities. Section 6402(c) covers past-due support, section 6402(d) covers past-due debts owed to federal agencies, section 6402(e) covers past-due state income tax, and section 6402(f) covers covered unemployment compensation debts owed to a state. Section 6402(f)(2) sets the order: federal tax first, then past-due support, then federal agency debts, then the state debts.

The Form 8379 instructions explain who sends the notice: the IRS issues offset notices for federal tax debts, and the Bureau of the Fiscal Service issues them for the other types of debt.

When the refund comes from a joint return, the offset sweeps in both spouses' share. That is what injured spouse relief fixes.

Who is an injured spouse

IRS Publication 504 says you are an injured spouse if you file a joint return and all or part of your share of the overpayment was, or is expected to be, applied against your spouse's past-due debts. To be considered an injured spouse, you must:

1. Have made and reported tax payments, such as federal income tax withheld from wages or estimated tax payments, or claimed a refundable tax credit such as the earned income credit or additional child tax credit on the joint return; and
2. Not be legally obligated to pay the past-due amount.

Publication 504 adds that if your permanent home is in a community property state, you must only meet the second condition.

The second condition is the one to look at closely. If the debt is one you are also legally obligated to pay, such as a joint tax debt from a year you filed together, you are not an injured spouse as to that debt. Injured spouse relief protects you from your spouse's separate debts, not from shared ones.

How the IRS figures your share

The Form 8379 instructions say income, deductions, credits and withholding are allocated as if each spouse had filed a separate return. Items go to the spouse who would have reported them. Items that do not clearly belong to either spouse are split equally. Joint estimated tax payments can be allocated by agreement between the spouses or by formula.

In practice, the refund attributable to your withholding and your share of credits comes back to you. The part attributable to your spouse goes to the debt.

Community property states

The rules are different if you lived in a community property state. The Form 8379 instructions list Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington and Wisconsin. In those states:

• For non-federal debts such as child support, student loans, state unemployment debts or state income tax, 50 percent of a joint overpayment, excluding the earned income credit, is applied to the debt.
• Federal tax offsets depend on state law.
• The earned income credit is allocated based on each spouse's earned income.

The instructions refer to Revenue Rulings 2004-71 through 2004-74 for the state-specific rules. The guide to community property and spousal relief covers how community property interacts with the other forms of spousal relief.

When and how to file

The Form 8379 instructions give you options:

• With your joint return, if you know the refund will be offset. Attach Form 8379 and write "Injured Spouse" in the upper left corner of page 1 of the return.
• With an amended joint return on Form 1040-X, used only when you are amending to claim a joint refund.
• By itself after the offset. Attach copies of all Forms W-2 and W-2G for both spouses, and any Forms 1099 showing withholding. Do not attach a copy of the joint return.

The instructions say Taxpayer Assistance Centers are not Service Centers and you cannot file Form 8379 by appointment there. Check the current instructions for where to mail it.

The deadline

The instructions say to file within 3 years of the original return's due date, including extensions, or within 2 years of the date the offset tax was paid, whichever is later. Section 6511 circumstances may extend that period.

How long it takes

The Form 8379 instructions give these estimates:

• About 14 weeks when filed on paper with a joint return.
• About 11 weeks when filed electronically with a joint return.
• About 8 weeks when filed separately after the joint return was processed.

Processing errors can make it longer.

When you should file preemptively

If you know at filing time that your spouse has a past-due child support obligation, a defaulted federal student loan, or a separate tax debt, file Form 8379 with the joint return. The faster processing is not the only reason. It also keeps you from waiting for an offset notice and then filing a second time.

Better yet, ask whether you should be filing jointly at all. Married filing separately keeps your refund out of your spouse's debts entirely, though it often costs more in total tax. The guide to filing separately after separation walks through that trade-off. For more on the practical side of the form, see this Form 8379 guide.

What injured spouse relief is not

The Form 8379 instructions are explicit: Form 8379 is not a request for innocent spouse relief. If you are asking to be relieved of liability for tax on a joint return, you file Form 8857 instead. And Form 8857 itself, at line 2, screens for injured spouse situations and points you back to Form 8379. Some people need both. The guide to injured spouse vs. innocent spouse explains how to tell them apart.

A short example

The Form 8857 instructions include a useful illustration. A joint return shows a refund of $3,200. One spouse owes $2,400 in back child support. The IRS applies $2,400 of the refund to the child support and refunds the remaining $800. The other spouse can file Form 8379 to get back his or her share of the $2,400.

If that spouse earned most of the wages and had most of the withholding, the share could be most of the $2,400. If the spouse with the child support debt earned most of it, the share will be smaller. The allocation follows the money.

Common mistakes on Form 8379

Filing Form 8857 instead. The two forms solve different problems. If the debt belongs only to your spouse, you need Form 8379.

Attaching the joint return when filing separately. The instructions say not to attach a copy of the previously filed joint return when filing Form 8379 by itself. Attach the W-2s, W-2Gs and any 1099s showing withholding instead.

Claiming items that are not yours. The allocation follows the separate-return rules. Your spouse's withholding and your spouse's credits stay with your spouse.

Waiting too long. The 3-year and 2-year rules apply. Older offsets can fall outside the window.

Assuming the offset was for a separate debt. Check the offset notice. If the debt is a joint tax liability, injured spouse relief does not apply, and you should look at innocent spouse relief instead.

The bottom line

If the debt belongs only to your spouse, the refund attributable to you belongs to you. Form 8379 is how you get it back. File it with the return when you can, and keep copies of your W-2s and withholding records.
