Tax Court denies innocent spouse relief for California taxpayer
Walsh v. Commissioner, T.C. Memo. 2025-91, No. 4460-22., 2025 BL 302504, Court Opinion
On August 26, 2025, the U.S. Tax Court in Walsh v. Commissioner held that Lisa Marie Walsh was not entitled to innocent spouse relief under Internal Revenue Code § 6015(b), (c), or (f) for tax years 2011–2016.
Walsh sought relief from joint and several liability on taxes owed with her former husband, Brendan Walsh.
The Court found she participated meaningfully in prior proceedings, benefited from unpaid taxes, and remained noncompliant after separation.
Why It Matters
The ruling reinforces how the doctrine of res judicata can bar a later claim for innocent spouse relief when the taxpayer took part—directly or through counsel—in a prior deficiency case covering the same years. It also underscores that lavish spending and continued noncompliance weigh heavily against equitable relief.
