Understanding IRS Form 8379: Injured Spouse Relief Explained

If you filed a joint tax return and your refund was taken to pay a debt that your spouse owes but not you, you might be able to get your share back by filing IRS Form 8379: Injured Spouse Allocation.

This form tells the IRS that you should not be held responsible for your spouse’s past-due debt, such as overdue child support, unpaid federal student loans, or back taxes. It allows the IRS to figure out how much of the refund belongs to you and return that portion. [1]

Married couples who file jointly are usually the ones who need to file this form. That’s because when you file jointly, the IRS treats both spouses as one taxpayer when it comes to refund payments, even if the debt belongs to only one spouse. 

A common example is this: You and your spouse are expecting a refund, but the IRS keeps all of it to cover your spouse’s defaulted student loan. You didn’t owe that loan, and you’re not responsible for it. In this case, Form 8379 can help you get back your portion of the refund. [2]

When Do You Need to File Form 8379?

You may need to file IRS Form 8379 if you filed a joint tax return, but your refund was taken (or “offset”) to pay a debt that belongs only to your spouse, not to you.

Here are some common reasons the IRS might take your refund:

• Past-due federal student loans
  If your spouse defaulted on a federal student loan, the IRS can use your joint refund to pay it. [3]
• Overdue child support or spousal support
  If your spouse owes child support from a previous relationship, your refund can be taken even if you aren’t legally responsible. [4]
• Unpaid federal or state taxes
  The IRS or state tax agencies can apply your joint refund toward your spouse’s unpaid tax bills.[5] 
  

In these situations, you are called the “injured spouse,” meaning your share of the refund was taken to pay a debt that you’re not responsible for. Filing Form 8379 helps tell the IRS that you want your portion of the refund to be returned to you. [6] 

Filing this form can help you recover your fair share of the tax refund without having to amend your return or file separately.

How the Injured Spouse Allocation Works

When you file Form 8379, the IRS will take a closer look at your joint tax return to figure out how much of the refund actually belongs to you, the injured spouse.

Here’s a simple breakdown of what the IRS does:

• They review your combined income, tax credits, and deductions.
• Then, they divide the refund fairly between both spouses based on each person’s contribution to the total tax return. [7]

The IRS looks at things like:

• How much money each spouse earned
• Which deductions or credits belong to which spouse
• Who paid more taxes through withholding or estimated payments [8] 

Example:

Let’s say you and your spouse are due a $3,000 refund, but your spouse owes $2,000 in past-due child support.

• You earned most of the income and paid most of the taxes.
• The IRS reviews your Form 8379 and decides $2,200 of the refund belongs to you, and $800 to your spouse.
• They send you your $2,200, and apply your spouse’s $800 to the child support debt.
  

This way, your share of the refund is protected, even if your spouse has old debts.

Keep in mind: The IRS does not automatically protect your refund just because your spouse owes money. You must file Form 8379 to request this allocation.

How to File Form 8379

You can file IRS Form 8379 (Injured Spouse Allocation) in two ways:

1. At the same time you file your joint tax return,  just include Form 8379 with your return.
2. Separately, after you’ve already filed your return, if you find out your refund was taken for your spouse’s debt.[9]
   

When filling out the form, here’s what you’ll need:

• Both spouses’ full names and Social Security Numbers (SSNs)
• A breakdown of each spouse’s income, tax credits, and deductions
• Details about how much each of you contributed to federal tax withholding or made estimated payments. [10] 

You’ll also need to indicate which tax items (like income or deductions) belong to you and which belong to your spouse. This helps the IRS decide how to divide the refund fairly.

How Long Does It Take?

• If you file Form 8379 with your tax return, it can take up to 14 weeks to process.
• If you file it after your return, it might take up to 8 weeks. [5]
  

Tip: Filing electronically and including Form 8379 with your e-filed return may speed up the process compared to mailing a paper form.[11]  

What’s the Difference Between Injured Spouse and Innocent Spouse Relief?

Many people confuse Injured Spouse Relief with Innocent Spouse Relief, but they are very different. It’s important to know which one applies to your situation.

Injured Spouse Relief

You use IRS Form 8379 when the IRS takes your part of a joint tax refund to cover a debt owed by your spouse, such as unpaid child support, past-due student loans, or old tax debts.

In this case, you’re not responsible for the debt, but your refund is still affected because you filed jointly. Filing Form 8379 helps you get back your share of the refund. [12] 

Innocent Spouse Relief

This is completely different. You would request Innocent Spouse Relief (Form 8857) if you’re being held responsible for taxes your spouse owed because of something they did wrong on the tax return, such as underreporting income or claiming false deductions and you didn’t know about it.

This type of relief is about protecting you from being liable for tax fraud or tax errors your spouse committed, not just refund offsets.[13] 

If your refund was taken but you didn’t do anything wrong on the return, you likely need Form 8379. If you’re being blamed for a mistake or fraud your spouse made on the return, you may need Form 8857.

FAQs About IRS Form 8379

If you’re thinking about filing Form 8379, it’s normal to have questions. Here are some of the most common ones we hear from clients:

1. Can I file Form 8379 every year?

Yes, you can file Form 8379 each year that your joint tax refund is taken for a debt that belongs only to your spouse. If this happens again in future tax years, you’ll need to submit a new Form 8379 for each year it applies. [14]   

2. Does Form 8379 affect my filing status?

No, filing Form 8379 does not change your filing status. You are still considered married filing jointly when you submit this form.

The form simply helps the IRS figure out how much of the joint refund belongs to you, the injured spouse, so they can return your fair share. [15] 

3. How long does it take to process Form 8379?

The processing time depends on when and how you file:

• If you file Form 8379 with your joint return, it may take up to 14 weeks. [16] 
• If you file it separately after the joint return, it usually takes about 8 weeks.[5]
  

Tip: Filing electronically with Form 8379 may help speed things up.

Conclusion

If your tax refund was taken because of a debt that only your spouse owes, you don’t have to lose your money. As an injured spouse, you may be entitled to get your share of the refund back, but only if you take action.
