Will You Be Held Responsible for Your Ex’s Tax Fraud?
Updated June 2026.
Discovering that your former spouse may have underreported income, failed to pay taxes, or filed an inaccurate tax return can be an unwelcome surprise. Many people assume that once a divorce is finalized, they are no longer responsible for tax issues that arose during the marriage. Unfortunately, that is not always the case.
When a joint tax return is filed, both spouses generally become legally responsible for the taxes reported on that return. As a result, the Internal Revenue Service (IRS) may seek payment from either spouse for unpaid taxes, penalties, and interest, even after a divorce. Depending on the circumstances, however, relief may be available.
Innocent Spouse Relief
In general, improperly reported or omitted items on a jointly filed tax return are the responsibility of both spouses. One potential exception is Innocent Spouse Relief.
To qualify, several requirements must generally be met:
First, the tax return at issue must have been filed jointly.
Second, you must establish that when you signed the return, you did not know and had no reason to know there was an understatement of tax.
Third, it must be determined that it would be unfair to hold you responsible for the resulting tax liability.
Finally, you and your former spouse must not have engaged in fraudulent transfers of assets.
Whether a taxpayer qualifies often depends on the specific facts and circumstances of the case.
Divorce Does Not Automatically End Tax Liability
One common misconception is that a divorce decree assigning responsibility for taxes to one spouse will prevent the IRS from pursuing the other spouse.
In reality, the IRS is generally not bound by agreements between former spouses. Even if a divorce decree states that your former spouse is responsible for certain tax obligations, the IRS may still attempt to collect from either spouse if a joint return was filed.
While the divorce agreement may create rights between the former spouses, it does not necessarily limit the IRS's ability to collect unpaid taxes.
How the IRS Evaluates a Spouse's Knowledge
A key issue in many Innocent Spouse Relief cases is whether the requesting spouse knew, or had reason to know, about the understatement of tax.
Actual knowledge is not the only consideration. The IRS will also evaluate whether a reasonable person in similar circumstances would have recognized that something was wrong.
For example, a spouse who had little involvement in the family's finances and relied on the other spouse to handle tax matters may be viewed differently than a spouse who actively participated in a business, reviewed financial records, or had access to information suggesting that income was not being reported correctly.
When making its determination, the IRS may consider factors such as:
The nature of the error and the amount involved
Each spouse's education, business experience, and financial background
Each spouse's participation in the business or financial activities that gave rise to the understatement
Whether the spouse seeking relief questioned the items reported on the return
Whether the tax reporting differed significantly from prior years
Whether the spouse benefited from the omitted income or improper deductions
No single factor controls the outcome. Instead, the IRS considers the totality of the circumstances when determining whether relief is appropriate.
Understanding Your Options
Learning that a former spouse may have filed inaccurate or fraudulent tax returns can be overwhelming, particularly when years have passed since the returns were filed. While Innocent Spouse Relief is often the best-known form of relief, other options may be available depending on the circumstances and the nature of the tax liability.
Every case turns on its own facts. Determining whether relief may be available often requires a careful review of the tax returns, financial records, and the taxpayer's involvement in the underlying activities.
