Identifying an "Applicable Corporation"
| Test Category | AFSI Threshold | Notes |
|---|---|---|
| U.S. Corporations | > $1 billion | 3-year average. Aggregation rules apply to controlled groups. |
| Foreign-Parented Groups | > $1 billion (worldwide) AND > $100 million (U.S. source) | The U.S. members of a foreign-parented multinational group are treated as a single applicable corporation if the group meets both thresholds on a 3-year average basis. |
QuantumLeap Tech LLC, a domestic limited liability company, was formed in 2026 by two members, Sarah and Tom, to develop a new AI platform. They anticipate significant net operating losses for the first two years, followed by substantial profits. Their tax advisor suggests they could remain a partnership (the default classification) to pass through the initial losses, or elect to be taxed as a C corporation from inception to benefit from corporate tax rates on future retained earnings. If they elect to be taxed as a C corporation for 2026, what is a critical long-term implication of this choice under the check-the-box regulations?
Worked Example: Gigantech Corp's CAMT Liability
Scenario. Gigantech Corp., a U.S. C-corporation, has been profitable for years. For the current tax year, its financial and tax data are as follows:
- Average 3-year AFSI: $1.3 billion (making it an applicable corporation) Net income before tax on its GAAP financial statement: $1.1 billion Federal income tax expense recorded on books: $150 million Taxable income for regular tax purposes: $600 million
- Let's calculate Gigantech's final tax liability.
- Step 1: Calculate Adjusted Financial Statement Income (AFSI) Start with GAAP net income and make necessary adjustments. Here, we adjust for federal income tax expense. Net Income per AFS: $1,100,000,000 Add: Federal Income Tax Expense: $150,000,000 AFSI = $1,250,000,000
- Step 2: Calculate Tentative CAMT Apply the 15% CAMT rate to the AFSI. Tentative CAMT = AFSI × 15% Tentative CAMT = $1,250,000,000 × 0.15 Tentative CAMT = $187,500,000
Common CPA Exam Distractors on IRC § 52(a)
- 1On the exam, follow this repeatable framework when you encounter a large C-corporation scenario:
- 2Step 1. Check for Applicability. Scan the facts for the 3-year average AFSI. If it exceeds $1 billion, CAMT is in play. If the problem only gives current year book income, assume the applicability test has been met if the income is substantial.
- 3Step 3. Calculate the Tentative CAMT. Multiply the calculated AFSI by the 15% CAMT rate. This is your first key figure.
- 4Step 4. Calculate the Regular Tax Liability. Take the corporation's regular taxable income (a separate figure) and multiply it by the 21% corporate tax rate. This is your second key figure.
- 5Step 5. Determine the Final Tax Liability and CAMT Credit. The corporation's final tax liability is the greater of the Tentative CAMT (Step 3) or the Regular Tax Liability (Step 4). If CAMT is higher, the difference creates a CAMT credit carryforward.
