768 F.Supp.3d 1324
D. Kan.2025Background
- The U.S. government sought to reduce to judgment civil tax penalties assessed against Allen R. Davison under 26 U.S.C. § 6700 for promoting abusive tax shelters.
- The IRS assessed penalties of $18,000 each for tax years 2009 and 2010 following Davison’s involvement in Cash Management Systems, Inc.'s tool plan tax shelters.
- Davison, a lawyer and former CPA, petitioned the U.S. Tax Court challenging the assessments; the Tax Court upheld the penalties, and its decision was affirmed on appeal after correcting a typographical error.
- The government filed this district court action within the statutory period to collect the outstanding penalties.
- Both parties moved for summary judgment; Davison asserted defenses including lack of proper assessment, incorrect calculation, selective prosecution, and statute of limitations.
