She had three controlled foreign corporations, shifting ownership percentages, and a three‑year scope test that would decide whether her team had a quiet filing season or a CAMT sprint. If that sounds familiar, take a breath. You can get this right with clean sources, steady process, and a few gotchas avoided.
Key Takeaways
- Schedule A is where you list each CFC’s per‑year, pro‑rata adjusted net income or loss described in section 56A(c)(3) for the three preceding tax years. You attach a separate Schedule A for each of those three years. These amounts roll into your AFSI and Part VI on Form 4626.
- Your source is Form 5471 Schedule H‑1, which computes each CFC’s adjusted net income or loss for CAMT. Use the weighted average exchange rate when converting AFS currency to U.S. dollars, and disregard income taxes included on the CFC’s AFS as required.
- For threshold testing, the general AFSI test is 1 billion, the FPMG additional test is 100 million, and the interim simplified method lets you test against 800 million and 80 million for returns not filed as of June 23, 2025. If you qualify for the simplified method and were not previously applicable, you indicate “Yes” to Form 1120 Schedule K question 29(c), and you do not file Form 4626.
- Do not net CFCs together on Schedule A. Enter each CFC’s positive or negative amount by year. When you aggregate for the applicable corporation determination, negative combined CFC amounts can become zero on the relevant line per instructions.
What Schedule A is and why it matters
Schedule A of Form 4626 captures, on a CFC‑by‑CFC basis, your pro‑rata share of each CFC’s adjusted net income or loss under section 56A(c)(3) for each of the three preceding tax years. If you have multiple CFCs, you list each one, then repeat for each prior year. These per‑CFC figures flow into Adjusted Financial Statement Income, then feed Part VI, which totals the aggregate pro‑rata CFC amounts used elsewhere on Form 4626. In short, Schedule A is the backbone for the CFC pieces of your CAMT scope and liability.
Tip, complete a separate Schedule A for each prior year column, then reference Part I and Part VI as your control totals. The 2024 instructions formalized this, which reduces confusion that existed when this lived on worksheets.
When you must complete Schedule A
If you are a U.S. shareholder of one or more CFCs and you are determining applicable corporation status or computing CAMT, you complete Schedule A for each of the three preceding tax years. If the corporation is a member of a foreign‑parented multinational group, the instructions tell some filers to enter zero on the specific line in Part I for the CFC aggregate, however Schedule A still documents the per‑CFC amounts driving your AFSI analysis and the entries that appear in Part VI.
Schedule A ties directly to the three‑year average AFSI test. For many groups, this is the page that determines if you cross the threshold and become an applicable corporation. Keep ownership periods accurate for each year, especially if percentages changed midstream due to acquisitions or restructurings.
Where the numbers come from
Use Form 5471 Schedule H‑1 as your base
Pull each CFC’s adjusted net income or loss from Schedule H‑1. That schedule starts with net income on the applicable financial statements and applies section 56A(c) adjustments to reach adjusted net income or loss for CAMT. Report the amounts in the AFS currency, then convert to U.S. dollars using the weighted average exchange rate. The H‑1 instructions reference proposed regulations for the exchange rate definition, and they remind you to disregard applicable income taxes taken into account on the AFS when computing the CAMT figure.
- If the CFC owns a disregarded entity, treat them as a single CAMT entity for the adjustment step on H‑1.
- If the CFC has depreciation differences on section 168 property, H‑1 has a specific adjustment line for the delta between book and section 167 depreciation, which then flows into the adjusted net income or loss you bring to Schedule A.
Map H‑1 to Schedule A columns cleanly
The 2024 instructions tell you how to complete each column:
- Column (a) Name, column (b) EIN or reference ID, column (c) country code.
- Column (d) current year net income or loss in U.S. dollars for the relevant year.
- Column (e) section 56A(c)(3) adjustments.
- Column (f) sum of columns (d) and (e).
- Columns (g) and (h) are reserved.
- Column (i) is your pro‑rata share of the CFC’s adjusted net income or loss to carry to Part I and Part VI where applicable.
Confirm that your pro‑rata share reflects the correct ownership for that year. If ownership changed midyear, follow the rules similar to section 951(a)(2) when sizing the pro‑rata amount. Keep your workpapers clear about timing, eliminations, and any translation support you applied on H‑1.
Keep your terminology straight
- AFSI is your adjusted financial statement income, the base for CAMT.
- CFC amounts on Schedule A are section 56A(c)(3) items, not Subpart F or GILTI taxable income measures.
- Part VI is where the CFC aggregate shows up inside Form 4626. You will still rely on Schedule A as the detailed backup for each CFC and each year.
Note, this article is general information, not tax advice. Always confirm positions with your advisors and the latest IRS guidance for the specific years you are filing.
Aggregation, controlled groups, and thresholds you must test
The core thresholds
You test applicable corporation status based on a three‑year average AFSI:
- General AFSI test, 1 billion average annual AFSI.
- FPMG AFSI test, the group must meet the 1 billion global test, and the U.S. member threshold is 100 million average annual AFSI.
If you use the IRS interim simplified method for returns not yet filed as of June 23, 2025, the thresholds drop to 800 million for the general test and 80 million for the FPMG U.S. member test. If you meet this interim safe harbor and were not already an applicable corporation in a prior year, indicate “Yes” to Form 1120 Schedule K question 29(c), and you do not file Form 4626 for that year.
Heads‑up, the IRS updated the simplified method in 2025. If you have older memos that cite 500 million or 50 million, update them to 800 million and 80 million for this interim method.
How aggregation works
For controlled groups under section 1563 and consolidated groups, AFSI is determined on a combined basis before you drop into Schedule A detail. Then you bring the CFC pro‑rata amounts in through Part I and Part VI with support from Schedule A and H‑1. Consolidated groups compute CAMT on a consolidated basis, so make sure the AFS you start from aligns with the consolidated presentation, then layer in the Schedule A CFC amounts correctly.
Terminating applicable corporation status
Once you become an applicable corporation, you generally stay in until you meet a termination rule. Proposed regulations describe two exit paths. First, a qualifying change in ownership can end status. Second, if you do not meet your applicable average AFSI test for five consecutive years, your status can terminate. Keep in mind, these are proposed rules, and the IRS continues to issue interim guidance while final regulations are pending.
Line‑by‑line mindset for Schedule A
Here is a simple way to avoid rework:
- Identify every CFC, legal name, EIN or reference ID, and country code.
- Tie each CFC’s H‑1 adjusted net income or loss for each of the three prior years.
- Apply your ownership percentage for that year to arrive at column (i) per CFC, and do not net across CFCs on this schedule.
- Repeat the process for each of the three prior years, attaching a separate Schedule A for each year as instructed.
Useful table, know your columns
| Schedule A column | What to enter | Source to tie |
| (a), (b), (c) | CFC name, EIN/reference ID, country code | Entity records, 5471 header |
| (d) | Current year net income or loss in USD | H‑1 base, after translation |
| (e) | Section 56A(c)(3) adjustments | H‑1 adjustments detail |
| (f) | Sum of (d) and (e) | Computed |
| (g), (h) | Reserved | n, a |
| (i) | Your pro‑rata share of adjusted net income or loss | Ownership schedule and H‑1 |
ProConnect Tax steps that actually work
You can generate Form 4626 and Schedule A in ProConnect with a few clicks once your workpapers are clean:
- Open Input Return, Taxes, Alternative Minimum Tax, then check Include Form 4626 with return.
- In the left panel, select Form 4626, Schedule A to add the CFC detail.
- Enter each CFC with three years of amounts backed by H‑1.
- Complete other AFSI adjustments in the Alternative Minimum Tax section so amounts flow to Form 4626 Parts I through VI.
- Review the populated totals, then compare to your H‑1 and consolidation workpapers.
If your corporation is a member of an FPMG, follow the instruction that tells you when a specific Part I line should be zero, and then maintain the Schedule A backup with H‑1 references in case an examiner requests it.
Common pitfalls and quick fixes
- Missing the separate Schedule A per year, the 2024 instructions require a separate schedule for each of the three prior years.
- Carrying AFS taxes into H‑1 adjusted net income, the CFC AFS tax is disregarded for CAMT. Reconcile this on H‑1 and document the line used.
- Ownership percentage drift, tie each year’s pro‑rata share to the correct period ownership. The wrong percentage in a prior year will throw off the three‑year average AFSI test.
- Using the old simplified method thresholds, update to 800 million and 80 million for the interim method and document the Schedule K question 29(c) position if out of scope.
Documentation tip, prepare a short “statement of rules” that maps each Form 4626 line you relied on to a notice, instruction, or proposed regulation, and keep it with your return file. It reduces back‑and‑forth if you are asked later.
Putting it all together with a quick example
Imagine you own three CFCs. One has adjusted net income, one has a loss, and one swings year to year. On Schedule A, you enter each CFC separately for each of the three prior years, apply the correct ownership for that year to get your pro‑rata amount, and resist any urge to net them on the page. Then you carry totals to Part I and Part VI as the instructions direct. If an aggregate for the CFCs is negative where the instructions tell you to enter zero, make that adjustment only at the form line, not on the Schedule A detail. The result is a clean audit trail for your AFSI testing and any CAMT computation.
FAQs, focused on Form 4626 Schedule A for CAMT
Who must complete Schedule A for Form 4626?
You complete Schedule A if you are a U, S. shareholder of one or more CFCs and you are determining applicable corporation status or computing CAMT. You attach a separate Schedule A for each of the three preceding tax years and then use Part VI for the aggregate CFC amounts inside Form 4626.
Where do the Schedule A numbers come from?
Use Form 5471 Schedule H‑1. It starts from AFS net income or loss, applies section 56A(c) adjustments, and then you convert to U.S. dollars using the weighted average exchange rate when needed. Disregard applicable income taxes included on the CFC’s AFS when computing the CAMT figure.
How do the 2025 simplified method thresholds work?
For original returns not filed as of June 23, 2025, the interim simplified method reduces the general test to 800 million and the FPMG U.S. member test to 80 million. If you are below the applicable thresholds and were not previously an applicable corporation, check “Yes” on Form 1120 Schedule K question 29(c) and you do not file Form 4626 for that year. Keep records supporting your safe harbor.
How do I handle consolidated groups and FPMGs?
Consolidated groups compute CAMT on a consolidated basis, so start with consolidated AFS and then feed in CFC amounts through Schedule A and Part VI. For FPMG members, follow the instructions that tell you when to enter zero on the specific Part I line and maintain backup.
When can applicable corporation status end?
Under the proposed regulations, status can terminate after a qualifying change in ownership or if you do not meet the applicable average AFSI test for five consecutive years. The IRS continues to update interim guidance while final rules are pending, so document your facts for each test year.
Checklist you can use before you file
- Confirm every CFC is listed with name, EIN or reference ID, and country code.
- Tie column (i) per CFC to H‑1 and your ownership by year, no netting across CFCs on the schedule.
- Attach a separate Schedule A for each of the three prior tax years.
- Reconcile Part VI totals to Schedule A and H‑1, then reconcile to the AFSI rollup.
- If using the interim simplified method, document the 800 million or 80 million test and check Form 1120 Schedule K question 29(c) as instructed.
