Read the latest tax rulings in our September edition of IRS Insights:

  • Supreme Court to Hear Challenge to Section 965 transition tax
    • The Supreme Court has agreed to hear a constitutional challenge to the Section 965 transition tax. If the Supreme Court invalidates the Section 965 transition tax, taxpayers may be entitled to refund but only if they filed a protective refund claim before the applicable refund statute of limitations expired.
  • IRS Offers Relief for Estimated Tax Payments for New Corporate Alternative Minimum Tax
    • In June 2023, the IRS announced penalty relief for corporations that did not pay estimated tax related to the new corporate alternative minimum tax (CAMT).
  • District Court upholds IRS denial of charitable deduction as assignment of income and due to lack of sufficient contemporaneous written acknowledgement
    • In Keefer v. United States,1 the district court granted partial summary judgment in favor of the government and held the Internal Revenue Service properly denied a charitable deduction stemming from the donation of a 4% limited partnership interest to a private foundation to establish a donor advised fund (“DAF”).
  • Supreme Court Rules on Notice Required for Third-Party Bank Account Summons
    • Recently, the Supreme Court ruled that third-party account holders could not challenge an IRS bank account summons on the basis that the taxpayer did not have a legal interest or title in the account.2
  • Court Holds that Signature Defects in a Claim for Refund Do Not Raise Jurisdictional Issues
    • In Lonnie Cooper v. United States,3 the taxpayer brought a refund suit to recover a late-filing penalty assessed in connection with his 2014 Form 1040, US Individual Income Tax Return. In deciding the case, the US Court of Federal Claims relied on binding precedent establishing that a signature verification defect on a refund claim does not raise jurisdictional issues.4
  • US Tax Court Holds that IRS Assessment was Untimely Following Adequate Disclosure of Gift
    • In Ronald Schlapfer v. United States,5 the US Tax Court granted the taxpayer’s Cross-Motion for Summary Judgment and determined that the taxpayer substantially complied with the adequate disclosure requirements when he filed Form 709, United States Gift (and Generation-Skipping Transfer) Tax Return, for the 2006 tax year. As such, the three-year period of limitations to assess gift tax expired before the IRS issued its notice of deficiency.
