Form 5471 is the single most consequential international information return in US tax. It captures ownership, control, transactions, and income inclusions for US persons with interests in foreign corporations. The form is information-only but the underlying §951A regime - now renamed Net CFC Tested Income (NCTI) under OBBBA for tax years beginning after December 31, 2025 - drives the actual tax. OBBBA delivered four structural changes: GILTI was renamed to NCTI, the §250 deduction dropped from 50% to 40% (effective rate rises 10.5% to 12.6%), the §960(d)(1) deemed-paid FTC cap rose from 80% to 90%, and the 10% QBAI deduction was eliminated. Downward attribution from foreign persons was restored, the §954(c)(6) look-through rule was made permanent, and Schedule H-1 is required for U.S. shareholders that are CAMT applicable corporations. Statutory penalties remain $10,000 base with $60,000 cap per CFC per year.
1. GILTI → NCTI rebrand. The regime under IRC §951A is now called Net CFC Tested Income. Same anti-deferral concept, different name and mechanics.
2. QBAI elimination. The 10% Qualified Business Asset Investment deduction (Net Deemed Tangible Income Return) is gone. The entire foreign tested income base is now potentially taxable - no more "high tangible asset" shelter.
3. §250 deduction 50% → 40%. Corporate shareholders previously received a 50% deduction against GILTI inclusions, producing a 10.5% effective rate (21% × 50%). The new 40% deduction produces a 12.6% effective rate (21% × 60%).
4. §960(d)(1) FTC haircut 20% → 10%. Foreign taxes deemed paid on tested income previously had a 20% reduction (80% creditable); now reduced by 10% (90% creditable). Meaningful improvement for high-tax jurisdictions.
5. Interest and R&E exclusion from NCTI basket. Per §904(b)(5), interest and R&E deductions are no longer apportioned against NCTI for FTC limitation purposes.
6. Downward attribution restored. The TCJA repeal of §958(b)(4) is itself repealed. Foreign-to-US downward attribution no longer creates artificial CFC status from nonresident spouse ownership.
7. Schedule H-1 for CAMT. Required for any U.S. shareholder that is an applicable corporation for corporate alternative minimum tax purposes (Instructions for Form 5471, filing-requirements table footnote 3).
| Category | Trigger | Schedule Burden |
|---|---|---|
| Category 1 | US shareholders of Specified Foreign Corporations (SFCs) under §965 transition tax | Limited - SFC-specific schedules |
| Category 2 | US citizen or resident who is officer or director of a foreign corporation in which a US person acquires a 10% stock interest or an additional 10% | Schedule O only |
| Category 3 | US person acquiring stock resulting in 10%+ ownership, or disposing/changing stock interest by 10%+, or becoming a US person while holding 10%+ | Limited - Schedule O, identifying schedules |
| Category 4 | US person who had CONTROL (more than 50% of vote or value) of the foreign corporation during the foreign corporation's annual accounting period | Heavy - 12+ schedules: A, B, C, E, E-1, F, G, G-1, H, H-1, I-1, J, M, P, Q, R |
| Category 5 | US shareholder (10%+) who owned stock of a CFC on the last day in the year the foreign corporation was a CFC (CFC status at any time during the foreign corporation's tax year) | Heavy - similar to Category 4. Splits into 5a, 5b, 5c subcategories |
A controlled foreign corporation under IRC §957(a) is any foreign corporation in which "United States shareholders" (each owning 10%+ of vote or value) collectively own MORE THAN 50% of the vote or value at any time during the foreign corporation's taxable year. The 50% test is by aggregate US shareholder ownership, not by any single shareholder.
| Element | Definition |
|---|---|
| "United States shareholder" | US person owning 10%+ of vote or value of the foreign corporation (§951(b)) |
| "More than 50%" | Bare majority - 50.0001% is sufficient; exactly 50% is NOT |
| Ownership test | Direct, indirect (through entities), and constructive (through family) per §958 |
| Time period | At any time during the foreign corporation's tax year (post-OBBBA, ownership on any day of year may trigger NCTI inclusion, not just last day) |
| Downward attribution | Restored under OBBBA 2026+. Foreign person's ownership is NOT attributed downward to US person. Reverses TCJA §958(b)(4) repeal. |
NCTI under §951A is the excess of aggregate tested income over aggregate tested loss. Under TCJA's GILTI regime (through 2025), the baseline was 10% of Qualified Business Asset Investment (QBAI). OBBBA eliminated QBAI - the entire net tested income of the CFC is now potentially included.
| Step | 2025 GILTI Calculation | 2026 NCTI Calculation |
|---|---|---|
| 1. Net CFC tested income | Sum of tested income less tested losses across all CFCs | Same |
| 2. Less QBAI exclusion | 10% × QBAI (Net Deemed Tangible Income Return) | ELIMINATED |
| 3. Less specified interest expense | Specified interest expense reduced the net deemed tangible income return | ELIMINATED (no net deemed tangible income return) |
| 4. = GILTI / NCTI inclusion | Result is GILTI | Result is NCTI - broader base |
| 5. §250 deduction (corporate shareholder) | 50% deduction | 40% deduction |
| 6. Effective tax rate | ~10.5% (21% × 50%) | ~12.6% (21% × 60%) |
| 7. FTC haircut under §960(d)(1) | 20% haircut (80% creditable) | 10% haircut (90% creditable) |
| 8. FTC effective coverage | Foreign effective rate of ~13.125% (foreign tax / pre-tax income, i.e., after the §78 gross-up) leaves no residual US tax (about 15.1% if measured against tested income net of foreign tax) | Foreign effective rate of ~14% (foreign tax / pre-tax income, i.e., after the §78 gross-up) leaves no residual US tax (about 16.3% if measured against tested income net of foreign tax) |
Facts: US corporation owns 100% of UK CFC. CFC tested income for 2026 = $1,000,000. Foreign tax paid = $200,000 (20% effective UK rate). No tested losses, no specified interest.
NCTI inclusion: $1,000,000 (no QBAI reduction, no interest deduction).
§250 deduction: 40% × $1,000,000 = $400,000.
Net NCTI taxable income: $600,000.
US corporate tax before FTC: 21% × $600,000 = $126,000.
§960(d)(1) FTC: deemed paid = 90% × 100% inclusion percentage × $200,000 = $180,000. §78 gross-up (taxes without the 90% factor) = $200,000, so the §250 base is $1,200,000, the §250 deduction is 40% × $1,200,000 = $480,000, taxable income is $720,000, and US tax before FTC is 21% × $720,000 = $151,200. The credit is limited by §904 to $151,200 (assuming no allocable expenses), so $28,800 of the $180,000 is unused.
Result: Net US tax on the $1M NCTI = $151,200 less $151,200 allowed FTC = $0. The $28,800 excess deemed-paid tax cannot be carried back or forward because §904(c) does not apply to taxes with respect to amounts described in §904(d)(1)(A).
Section 954(c)(6) allows certain related-party payments between CFCs (dividends, interest, rents, royalties) to be excluded from Subpart F income if attributable to the payor CFC's active income. The rule was originally enacted as a temporary provision in 2006 and had been extended repeatedly. OBBBA made it permanent.
For boutique tax practices and multinational families, this matters: a Cayman holding company receiving dividends from a Singapore operating subsidiary will not have Subpart F inclusion for the dividend if the underlying Singapore income is active business income. The rule eliminates a major friction point in intra-group structures and provides long-term planning certainty.
Subpart F under §951 predates GILTI/NCTI and continues to operate in parallel. Subpart F captures specific categories of "tainted" income that the IRS taxes currently regardless of distribution. Categories include:
| Subpart F Income Category | Authority |
|---|---|
| Foreign personal holding company income (interest, dividends, royalties, rents, gains) | §954(c) |
| Foreign base company sales income (related-party sales lacking economic activity) | §954(d) |
| Foreign base company services income (services to related parties outside CFC's country) | §954(e) |
| Insurance income | §953 |
| Boycott income | §952(a)(3) |
| Illegal bribes, kickbacks | §952(a)(4) |
| Income from §901(j) sanctioned countries (Cuba, Iran, North Korea, Syria, Sudan, in part) | §952(a)(5) |
Subpart F inclusions reduce NCTI tested income for the same CFC - the income is already taxed under Subpart F, so it does not double-count in NCTI. The ordering matters and is reflected on Schedule I of Form 5471.
Individual US shareholders of CFCs face the worst of both worlds without planning: NCTI and Subpart F inclusions taxed at ordinary individual rates (up to 37%) with no §250 deduction. The §962 election allows an individual to be taxed at corporate rates on inclusions, accessing the §250 deduction and FTC mechanics available to C-corp shareholders.
| Without §962 (Individual Default) | With §962 Election |
|---|---|
| NCTI taxed at up to 37% individual rate | NCTI taxed at 21% corporate rate |
| No §250 deduction | 40% §250 deduction available |
| No deemed-paid FTC under §960 | FTC under §960(d)(1) available (90% post-OBBBA) |
| Distributions later are dividend income (qualified rate if treaty country) | On later distributions, earnings attributable to the §962 inclusions are included in gross income to the extent they exceed the tax paid on those inclusions (§962(d)); only the remainder is excluded as PTEP |
| Effective rate could be 30%+ | Effective rate roughly 12.6% on inclusions |
When a US shareholder includes NCTI or Subpart F income in the current year, those earnings become Previously Taxed E&P (PTEP) under §959. When the CFC later distributes those earnings as a dividend, the PTEP comes back tax-free at the shareholder level (it was already taxed currently). PTEP tracking is one of the most error-prone areas of Form 5471 preparation.
| PTEP Bucket | Origin |
|---|---|
| §959(c)(1) PTEP | Investments in US property (Subpart F §956 investments) |
| §959(c)(2) PTEP | Subpart F income inclusions |
| §959(c)(2) PTEP - §965 inclusions | §965(a) and (b) transition tax (mandatory repatriation) |
| §959(c)(2) PTEP - GILTI/NCTI | §951A inclusions (now NCTI for 2026+) |
| §959(c)(3) E&P | Not yet taxed - subject to future Subpart F or NCTI inclusion or eventual qualifying dividend |
Schedule J of Form 5471 tracks E&P with PTEP and non-PTEP layers by category. Schedule P tracks PTEP movements with previously-taxed account information. Both schedules are required for Category 4 and 5 filers and create compounding complexity over multi-year CFC ownership.

Form 5471 is for OUTBOUND - US person with interest in a foreign corporation. Form 5472 is for INBOUND - foreign-owned US corporation reporting transactions with foreign owner. Different rules, different penalties (Form 5472 has higher $25,000 base penalty). Disregarded entity (LLC) wholly owned by foreign person also files Form 5472.
The §958 attribution rules can create filing obligations even when direct ownership is below 10%. Family attribution under §318 (modified by §958(b)) attributes ownership among spouses, children, parents, grandchildren. A wife with 8% direct ownership plus a husband's 3% may have 11% combined - triggering filing for both.
CFC distributions are sourced first from §959(c)(1) PTEP, then §959(c)(2) PTEP, then §959(c)(3) (untaxed E&P). Practitioners who source from untaxed E&P first will compute too much dividend income and too little tax-free PTEP recovery. The error compounds across years.
Schedule H-1 (Form 5471) is required for any U.S. shareholder that is an applicable corporation for corporate alternative minimum tax (CAMT) purposes (see the Instructions for Form 4626). A required schedule that is omitted makes the Form 5471 incomplete, which can result in the §6038(b) penalty. A corporation that is not an applicable corporation is not required to file it.
Schedule C and Schedule J amounts must be in functional currency of the CFC and translated to USD for E&P tracking. Practitioners who fail to use IRS-published yearly average rates (https://www.irs.gov/individuals/international-taxpayers/yearly-average-currency-exchange-rates) for translation produce unreliable PTEP tracking that propagates across years.
The §962 election is made annually on a timely-filed return (including extensions). It cannot be made on a late or amended return. Individual shareholders with significant CFC inclusions who fail to elect §962 on the original return lose the planning benefit for that year - the difference can be 20+ percentage points of effective rate.
Pre-OBBBA, §951 required ownership on the LAST day of the CFC's tax year for inclusion. OBBBA changed this for taxable years of foreign corporations beginning after 12/31/2025 (P.L. 119-21 §70354(c)(1)) - a U.S. shareholder owning stock on ANY day of the CFC year includes its pro rata share of subpart F income (§951(a)(1)(A)) and NCTI (§951A(c)(2)); the §956 amount still turns on ownership on the last day the corporation is a CFC (§951(a)(1)(B)). A US person who sells CFC stock mid-year may now have NCTI for the portion of the year owned, where previously they had nothing.
State conformity to NCTI/GILTI varies dramatically. California, New York, New Jersey, and Massachusetts have specific rules that often diverge from federal treatment. A federal §250 deduction may not be available at state level, producing materially higher state effective rates on NCTI inclusions.
