When Joint Tax Liability Feels Unfair: Limits on Innocent Spouse

When it comes to joint tax returns, the Internal Revenue Code has a bit of a "two for one" deal: both spouses are jointly and severally liable for the taxes owed on their combined income (Int. Rev. Code, § 6013(d)(3)). Simply put, even if only one spouse earned all the income, both are on the hook for the full tax bill. But don't worry—there’s a safety net! The tax code allows for 'innocent spouse' relief under Internal Revenue Code section 6015, which can help when this rule seems a bit unfair.


Here’s how section 6015 offers a lifeline:

  1. Relief from Understatement: If the requesting spouse didn’t know about the tax understatement (Int. Rev. Code, § 6015(b)).
  2. Relief for the Separated or Divorced: For those who are no longer together (Int. Rev. Code, § 6015(c)).
  3. Equitable Relief: When it wouldn’t be fair to hold the requesting spouse responsible (Int. Rev. Code, § 6015(f)).


To snag relief under section 6015(f), a few boxes need to be checked:

  • You must have filed a joint return for the tax year(s) in question.
  • Options under sections 6015(b) or (c) can’t be used.
  • The request must be timely.
  • No fraudulent asset transfers between you and your spouse.
  • No 'disqualified assets' were transferred to you from your spouse.
  • You didn’t knowingly take part in a fraudulent return.
  • The tax liability should be partially or fully linked to your spouse’s income (with some exceptions).


If you meet these basic criteria, you might be eligible for streamlined relief if:

  • You’re no longer married to the non-requesting spouse.
  • Not getting relief would cause economic hardship.
  • You didn’t know or have reason to know that your spouse wouldn’t or couldn’t pay the taxes owed, with exceptions for abuse cases.


Even if streamlined relief doesn’t fit your situation, you might still get relief based on equitable factors like:

  • Changes in marital status.
  • Economic hardship.
  • Knowledge about your spouse’s ability to pay.
  • Legal obligations to cover the taxes.
  • Benefits you received from the unpaid taxes.
  • Your compliance with tax laws in the years following the issue.
  • Your physical or mental health.


A recent case, Thomas v. Commissioner (Jan. 30, 2024, No. 12982–20) brings this to life. Sydney Thomas sought relief after filing jointly with her husband, Tracy, during years with unpaid taxes. Although she met some of the criteria, her request was denied due to factors like her awareness of the unpaid taxes and the significant benefits she enjoyed from them.


The Thomas case shows that while section 6015(f) relief is available, it’s not a catch-all. If you’ve got personal resources and have used them for luxury instead of paying off taxes, the IRS and the Tax Court might not be so lenient.

Circumstances change—often in ways we never anticipated. Whether you’ve lost your job, received a significant promotion, or encountered unexpected health issues, life’s twists and turns can impact your financial stability. For many former spouses, these changes may prompt revisiting alimony arrangements. In California, modifying spousal support isn’t automatically guaranteed; it requires meeting specific legal criteria and following a structured process. At M.C. Law, P.C., in Los Angeles, we’re here to help you understand when and how adjustments to alimony payments may be appropriate, ensuring that both parties maintain a fair and balanced agreement. Recognizing Valid Grounds for Modification Not all changes in circumstances warrant a modification to spousal support. California courts typically consider requests if there has been a “material change” in either party’s financial situation—such as a substantial drop in income, a significant increase in the recipient’s earnings, or new medical expenses affecting a party’s ability to work. The burden of proof rests with the individual seeking the modification, who must demonstrate that the shift in financial standing is both legitimate and enduring. An experienced attorney can help you assess whether your situation meets the threshold for revisiting your alimony terms. Initiating the Legal Process Before you file a request with the court, reviewing your original divorce decree or settlement agreement is important. Some agreements may include specific terms outlining when and how spousal support can be modified. Assuming these options are available, you’ll need to prepare and submit a formal request for a modification to the court. This involves completing the required legal forms, attaching financial documentation, and serving the other party. At M.C. Law, P.C., we guide clients through this complex process, ensuring each step is completed accurately and fully in compliance with state requirements. Gathering Comprehensive Evidence To strengthen your case, you must provide solid evidence that your financial circumstances have changed and justify an adjustment. Relevant documentation may include recent pay stubs, bank statements, tax returns, medical bills, or termination letters from an employer. The more comprehensive and organized your evidence is, the better your chances of a successful modification. Our legal team helps clients compile the strongest possible evidentiary record, saving them time, effort, and potential frustration in a challenging moment. Considering Negotiation, Mediation, or Court Action Not every modification request has to result in a court battle. In some cases, both parties may be willing to negotiate an updated arrangement on their own or through mediation, resulting in a mutually agreeable solution with fewer legal expenses and emotional strain. If these methods fail, the matter may go before a judge who will evaluate the request and render a decision. Regardless of your route, having skilled legal counsel on your side can help you effectively present your case, anticipate counterarguments, and confidently navigate the legal landscape. Adjusting alimony arrangements can feel daunting, but it may be right when your life’s circumstances shift significantly. Understanding the legal grounds, following proper procedures, and presenting compelling evidence can position yourself for the best possible outcome. The team at M.C. Law, P.C. in Los Angeles stands ready to assist you—whether you want to modify your existing support payments or defend against an unwarranted request. With professional guidance, you can ensure that your spousal support reflects the reality of your current situation while maintaining fairness for both parties involved.
