💡 Accountant's Note
MLB's Competitive Balance Tax (CBT — the luxury tax) for 2023: $233M threshold. Tax rates: First-time violators: 20% on first $20M over, 32% on $20–40M over, 62.5% on $40M+ over. For fourth-time consecutive violators (Dodgers, Yankees historically): rates reach 90–110% on the highest tier. The Dodgers' 2023 payroll exceeded the threshold by $100M+ — generating CBT taxes in the tens of millions. Unlike the NBA, MLB's CBT doesn't fully redistribute to non-payers — a portion funds player benefits and revenue sharing pools. Draft pick penalties (loss of highest draft pick) compound the financial impact for persistent violators. The accrual uses projected season-end payroll against the threshold — updated as offseason signings and trades occur.
Practitioner & Systems Framework
💻 ERP Architecture
MLB payroll for CBT purposes uses a 'AAV' (Average Annual Value) system — multi-year contracts are counted at their average annual value, not their current-year cash obligation. This creates a difference between: (1) GAAP compensation expense (actual wages paid in the year), (2) CBT payroll (AAV of all contracts), and (3) Cash obligations. Teams must maintain all three parallel calculations. Deferred salary arrangements (common in MLB — Bobby Bonilla famously defers) affect both CBT and GAAP differently.
⚠️ Audit Flags
Auditors test the CBT calculation against the official MLB payroll certification (teams must certify payroll to the Commissioner's Office). AAV calculations for complex multi-year contracts with option years, performance bonuses, and deferred compensation require detailed verification. The repeat violator determination (affecting tax rates) requires reviewing 5+ years of CBT history.
