IRS Form 8379, Injured Spouse Allocation, is how you get back your share of a joint tax refund the IRS applied to your spouse's separate past-due debt — back federal or state taxes, child or spousal support, or a federal nontax debt such as a defaulted student loan. JustFill makes the official PDF fillable in your browser — no printing, scanning, or installs. The two-page form has four parts: Part I screens whether you qualify as an injured spouse with yes/no questions, Part II records the joint return details, Part III splits income, deductions, credits, withholding, and payments between the two of you so the IRS can compute your share, and Part IV holds the signature when you file the form on its own. You can attach it to your joint return before an offset happens or file it by itself after the IRS keeps your refund.
What each section of Form 8379 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.
Yes/no screener: the tax year, whether you filed jointly, whether the joint overpayment went to your spouse's separate past-due debt, whether you are legally obligated on that debt, community property residence, and your own payments, earned income, and credits.
Both spouses exactly as shown on the joint return, in the same order, with a checkbox marking who is the injured spouse.
Check only if you want the refund issued in both names; otherwise the IRS issues separate refunds where applicable.
Yes/no plus an address if you want the injured spouse refund mailed somewhere other than the address on the joint return.
W-2 wages and all other income, split across three columns: amount on the joint return, allocated to the injured spouse, allocated to the other spouse.
Adjustments to income, standard or itemized deductions, nonrefundable credits, and refundable credits (excluding any earned income credit), each allocated between spouses.
Other taxes, federal income tax withheld, and estimated or other payments, allocated the same way.
Sign and date only when filing Form 8379 by itself; skip this part when the form is attached to your tax return.
