Real-World Scenario

Scenario: C-Corp has receipts: $10M (Year 1), $35M (Year 2), $40M (Year 3).

  • 3-year average: ($10M + $35M + $40M) / 3 = $28.3M.
  • Tax Year 2024 threshold: $30M.
  • Result: Qualifies for cash method ($28.3M < $30M).

On the Exam

Expect 4-5 questions on methods, typically:

  1. Method Questions: "Can this C-Corp use cash method?"
  2. 12-Month Questions: "Prepaid insurance—deductible when?"
  3. Threshold Questions: "What is the gross receipts limit?"

The key is to remember: Cash = received/paid. Accrual = All Events Test. $30M threshold (Tax Year 2024). Tax Shelters = never cash. 12-month rule for prepaid expenses.
