2025 TC Memo 91
Tax Ct.2025Background
- Lisa Marie Walsh seeks relief from joint and several tax liability for tax years 2011–2016, alleging entitlement to "innocent spouse" relief under § 6015(b), (c), and (f).
- Walsh and her former husband filed joint tax returns for the years in question, incurring significant underpayments and understatements of federal income tax, enabling them to maintain an affluent lifestyle.
- The IRS previously issued deficiency notices, and the couple jointly petitioned the Tax Court; the matters were settled without raising innocent spouse relief.
- Walsh subsequently divorced, was held jointly responsible for the tax debt by the California Superior Court, and has since filed late or incomplete returns with continued compliance issues.
- Walsh's request for relief was denied by the IRS; she then timely petitioned the Tax Court for review.
- The primary legal question is whether claim/issue preclusion (res judicata) and/or the equitable factors of § 6015(f) prevent her from obtaining innocent spouse relief.
Issues
| Issue | Walsh's Argument | IRS's Argument | Held |
|---|---|---|---|
| Eligibility for relief under § 6015(b), (c), (f) | Walsh did not participate meaningfully in prior case, so barred relief shouldn’t apply | Walsh participated meaningfully in prior Tax Court proceedings; relief barred | Res judicata bars 2011–2013 claims—Walsh meaningfully participated |
| Streamlined Equitable Relief (§ 6015(f)) | Would suffer economic hardship if relief not granted; liabilities from ex-spouse's income | No economic hardship—Walsh's income exceeds threshold and expenses unproven | Not entitled: Economic hardship not established |
| Full Equitable Relief (§ 6015(f) totality) | Shouldn’t be held liable given ex-spouse's control and her claimed lack of knowledge | Walsh knew/should have known, benefited from lifestyle, had compliance issues | Relief denied: Knowledge, benefit, and compliance factors against her |
| Divorce/legal obligation impact | Divorce decree made ex-husband solely liable for taxes | Divorce decree makes both jointly liable | Neutral: Both remain jointly liable under divorce order |
