Form 8379 Recovery Calculator

When you file jointly and the IRS seizes your refund to pay your spouse’s pre-existing debt, you’re not powerless. Form 8379 (Injured Spouse Allocation) allows you to recover your portion of the refund by proving which income, withholding, and payments were yours versus your spouse’s. The IRS will recalculate the joint return, allocate amounts to each spouse, and send you your share while applying your spouse’s portion to their debt. This calculator estimates how much of your seized refund you can potentially recover, helping you decide whether filing Form 8379 is worth the 8-14 week processing time.

What is Form 8379 and When to Use It

Form 8379 (Injured Spouse Allocation) is different from Innocent Spouse Relief (Form 8857). Use Form 8379 when you filed jointly, your refund was offset to pay your spouse’s separate debt (back taxes, student loans, child support, or other federal/state obligations), and you want to recover your portion of that refund. You’re not claiming you shouldn’t be responsible for tax on the return—you’re claiming your share of the refund before it goes to your spouse’s debt. This only works if you had income, withholding, or made tax payments that contributed to the refund.

How the IRS Allocates Your Refund

The IRS uses Form 8379 to separate a joint return into individual portions. They allocate income based on who earned it (your W-2 goes to you, spouse’s W-2 goes to them). For joint bank account interest or jointly-owned assets, they typically split 50/50 unless you can prove different contribution percentages. Withholding is allocated based on whose paycheck it came from. The IRS then recalculates the tax liability for each spouse separately, determines how much of the refund came from each person’s income and payments, and sends you your allocated portion while applying your spouse’s portion to their debt.

Filing Form 8379 Proactively vs Retroactively

You can file Form 8379 in two ways: proactively with your original joint return if you know your spouse has debt and expect offset, or retroactively after the offset has already occurred. Filing proactively (attached to the original return) means the IRS processes your allocation before sending any refund, preventing the offset from affecting your portion. This takes about 11-14 weeks. Filing retroactively (after offset occurred) requires mailing Form 8379 separately to the IRS, which also takes 8-14 weeks for processing. Either way, you’ll receive a paper check for your allocated portion—direct deposit is not available for Form 8379 refunds.

Frequently Asked Questions

Can I file Form 8379 every year?

Yes, but Form 8379 only applies to the specific tax year you file it for—it doesn’t carry forward to future years. If your spouse’s debt persists into next year and you file jointly again, you’ll need to file Form 8379 again with that year’s return to protect your portion. The form does not permanently allocate all future refunds. Consider filing separately in future years if your spouse’s debt will take years to resolve.

What if we live in a community property state?

Community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin) have special rules. Even when filing separately, you typically must report 50% of all community income (income earned during marriage by either spouse). When filing Form 8379 in these states, allocation becomes more complex. The IRS may allocate income and withholding differently than in common-law states. Strongly consider consulting a tax professional in community property states for accurate Form 8379 completion.

Does Form 8379 work for state tax refunds?

Form 8379 only applies to federal tax refunds offset by the Treasury Offset Program. Many states have similar injured spouse protections for state refunds offset for state debts, but they use different forms and processes. Check your state’s department of revenue website for the equivalent state form and instructions. You may need to file both federal Form 8379 and a state-specific form to recover both federal and state refund portions.

What if my spouse won’t sign Form 8379?

Both spouses must sign Form 8379 because it relates to a jointly filed return. If your spouse refuses to sign and you cannot obtain their signature, your options are limited. For future years, you can file separately (Married Filing Separately status), which doesn’t require spouse cooperation and protects your refund entirely. For the current year’s already-offset refund, you may need legal assistance or may not be able to recover your portion without spouse cooperation.
