September 30, 2026

The court held that taxpayers cannot terminate a fixed-date Form 872 consent to extend the assessment period by submitting Form 872–T, which is designed to terminate Form 872–A. Because the taxpayers’ Forms 872 remained effective when the IRS issued the deficiency notices, the notices were timely and the Commissioner…

Tax CourtHough Beck & Baird, Inc.

July 8, 2026

The Court held that the Commissioner properly used a supplemental assessment to recover employment taxes that had been mistakenly assessed as zero and refunded to petitioner. Because the erroneous assessment misstated petitioner’s liability by the entire amount of its reported employment tax, it was imperfect in a…

Tax CourtJohn R. Dee

July 2, 2026

Tax CourtThe Diversified Group Incorporated

February 23, 2026

The court held that petitioners’ receipt of letters offering review by IRS Appeals gave them an opportunity to dispute their section 6707 penalty liabilities, so they could not challenge those liabilities in their CDP hearings or in this Court.

Tax CourtPatricia A. Torres

September 11, 2025

The Tax Court held that wages disallowed as deductions under section 280E do not count as “W–2 wages” when calculating the section 199A deduction. It reasoned that section 199A excludes from qualified business income items not allowed in determining taxable income, so those wages cannot be properly allocable to…

Tax CourtJohn F. Carter

October 3, 2024

The Tax Court held that the petitioner’s bankruptcy filing did not automatically stay his pending whistleblower-award case under 11 U.S.C. § 362(a)(8), because the Court’s review of the award denial could not affect his tax liability.

Tax CourtPeter F. McDougall, Donor

September 17, 2024

Applying the principles of the QTIP regime, the court held that Bruce made no taxable gift in connection with the trust commutation and related transactions, even assuming a transfer occurred under section 2519.

July 17, 2024

Tax CourtThe Coca-Cola Company and Subsidiaries v. Commissioner

November 18, 2020155 T.C. No. 10

The Tax Court concluded that the Commissioner did not abuse his discretion by using a comparable profits method with the supply points as tested parties and independent bottlers as comparables, and that the resulting allocation required recomputation of the Mexican branch’s section 987 losses.

Tax CourtDavid Casimer Brzyski v. Commissioner

August 27, 20202020 T.C. Summary Opinion 25

The court held that Brzyski was not entitled to the claimed dependency exemptions, head-of-household status, child tax credits, or earned income tax credit for 2016. He did not prove that he was married to the children’s mother and therefore could claim the children as stepchildren; the children also did not meet the…

The Tax Court granted the whistleblower’s motion to compel production of requested audit documents. It concluded that deciding the Commissioner’s unsettled statutory argument about when the IRS proceeds on whistleblower information was not appropriate in this discovery dispute, and that the Commissioner had not shown…

Tax CourtLaw Office of John H. Eggertsen P.C. v. Commissioner

October 1, 2014143 T.C. No. 13

The Tax Court granted the Commissioner's motions for reconsideration and to vacate its prior decision. It held that the general limitations provision in section 6501 governs because the specific provision in section 4979A(e)(2)(D) only extends the section 6501 period, and the taxpayer filed no qualifying return for…

Tax CourtBruce E. Phillips v. Commissioner of Internal Revenue

September 10, 2013106 T.C.M. 288

The Tax Court allowed the Commissioner to amend the answer because Phillips had notice of the issues and would not be prejudiced. It found that his bowling was not conducted with an actual and honest profit objective, and that he could not substantiate any Schedule C deductions even assuming a profit motive.

The court held that the 1993 deficiency was time-barred because the return preparer’s error was negligent, not fraudulent, but that the assessment periods remained open for 1994 and 1995 because the preparer fraudulently understated tax, and were extended to six years for 1996 and 1997 because substantial income was…
