Form 8992 is the form on which a US shareholder of a controlled foreign corporation (CFC) works out its GILTI inclusion — the share of the CFC's current profits the United States taxes the shareholder on right away, instead of waiting for a dividend — and carries the result onto the Form 1040 or Form 1120. The computation is genuinely involved: tested income and tested loss across every CFC, the deduction that softens it, and a foreign tax credit all feed the number. This guide is not about doing that arithmetic. It is about the question that comes first — is there a US shareholder of a CFC in the structure at all? — because that single status is what puts Form 8992 on the table.
That status is the same one that drives Form 5471: a 10%-or-greater US shareholder of a foreign corporation that is a CFC. PILOT determines it once, from the ownership facts, and the moment a CFC appears, Form 8992 becomes potentially required. What PILOT does not do — and what this guide is careful never to claim it does — is compute the GILTI inclusion, the deduction, the credit, or the tax. That is the Professional's work. Form 8992 is PILOT's first Potential-tier form for exactly this reason: the filing trigger is a status PILOT can determine, but the form's substance is a computation it deliberately leaves alone.
In plain terms there is one gate: is your client a 10%-or-greater US shareholder of a controlled foreign corporation? If yes, Form 8992 is in play, and PILOT flags it the moment it sees the CFC — the same finding that produces the Form 5471 obligation. Whether your client ends up owing any GILTI tax is a separate calculation that depends on the CFC's numbers, and that calculation is for the Professional. The flag is the determination; the math is not.
What GILTI is, and what Form 8992 does
GILTI — for tax years beginning after 2025, renamed net CFC tested income (see What OBBBA changed for GILTI below) — is an anti-deferral rule. Left alone, a US owner of a foreign corporation pays no US tax on the corporation's active earnings until they are distributed. Subpart F closed that door for certain mobile, passive income decades ago; the 2017 Act's GILTI regime closed it much more widely, sweeping in most of a CFC's active earnings above a routine return on its tangible assets. The statute states the inclusion in one sentence:
Each person who is a United States shareholder of any controlled foreign corporation for any taxable year of such United States shareholder shall include in gross income such shareholder's net CFC tested income for such taxable year.
— IRC §951A(a)
Form 8992 is where that inclusion is computed and reported. The US shareholder gathers each CFC's tested income or tested loss, nets them, and (for tax years through 2025) reduces the result by a net deemed tangible income return equal to 10% of the CFCs' qualified business asset investment (QBAI) less certain interest expense. The remaining amount is the inclusion, which flows to the shareholder's Form 1040 or Form 1120. The form has two schedules: Schedule A lists the CFCs and their tested items one corporation at a time, for a US shareholder that is not in a consolidated group; Schedule B replaces Schedule A for a member of a US consolidated group, which completes one consolidated Form 8992 for the group.
In plain terms Form 8992 is a worksheet that turns "my client owns a CFC" into "this is the slice of that CFC's profit my client must include this year." The harder the structure — several CFCs, some profitable and some not, with tangible assets and intercompany interest — the more there is to compute. PILOT does not run that worksheet; it tells you the worksheet is required, for whom, and why.
Who must file — a US shareholder of a CFC
Two definitions decide whether anyone is in scope, and they are identical to the ones behind Form 5471. First, a US shareholder is a 10% owner:
the term "United States shareholder" means, with respect to any foreign corporation, a United States person (as defined in section 957(c)) who owns (within the meaning of section 958(a)), or is considered as owning by applying the rules of ownership of section 958(b), 10 percent or more of the total combined voting power of all classes of stock entitled to vote of such foreign corporation, or 10 percent or more of the total value of shares of all classes of stock of such foreign corporation.
— IRC §951(b)
Second, the foreign corporation must be a CFC — more than 50% owned, by vote or value, by those 10% US shareholders:
the term "controlled foreign corporation" means any foreign corporation if more than 50 percent of— (1) the total combined voting power of all classes of stock of such corporation entitled to vote, or (2) the total value of the stock of such corporation, is owned (within the meaning of section 958(a)), or is considered as owned by applying the rules of ownership of section 958(b), by United States shareholders on any day during the taxable year of such foreign corporation.
— IRC §957(a)
Put the two together and the rule for Form 8992 follows. The regulation that actually requires the form says so directly:
Except as provided in paragraph (d) of this section, each United States person who is a United States shareholder (as defined in section 951(b)) of any controlled foreign corporation (as defined in section 957) must make an annual return on Form 8992 ... for each U.S. shareholder inclusion year ....
— Treas. Reg. §1.6038-5(a)
Three things follow. First, the obligation runs to a US shareholder who owns section 958(a) stock — direct or indirect ownership through foreign entities. A person who is a US shareholder only by section 958(b) constructive attribution, and owns no section 958(a) stock, falls within the single exception: paragraph (d) excuses "any United States person that does not own, within the meaning of section 958(a), stock of a controlled foreign corporation in which the United States person is a United States shareholder." Second, the inclusion lands on the US persons who actually own that section 958(a) stock — in practice, US individuals and US C corporations — because the section 958(a)(2) attribution chain stops at the first US person. Third, and most importantly, this is the same determination as Form 5471: confirm the 10% US shareholders, confirm the foreign corporation is a CFC, and the Form 8992 question is answered at the same time. PILOT does not re-derive it; it reuses the CFC and US-shareholder findings it already made.
The partnership and S-corporation pass-through
When a domestic partnership or S corporation sits between the US owners and the CFC, the analysis splits in two — and getting the split right is the single most-missed point on Form 8992. For the inclusion, the domestic partnership is transparent:
Except as otherwise provided in paragraph (d)(2) of this section, for purposes of sections 951, 951A, and 956(a) ... a domestic partnership is not treated as owning stock of a foreign corporation within the meaning of section 958(a). For purposes of determining the persons that own stock of the foreign corporation within the meaning of section 958(a) ..., stock of a foreign corporation owned by a domestic partnership is treated in the same manner as stock of a foreign corporation owned by a foreign partnership ....
— Treas. Reg. §1.958-1(d)(1)
So the partnership does not have a GILTI inclusion and does not file Form 8992; the inclusion flows up to its partners, each of whom applies the 10% US-shareholder test at their own level. The Form 8992 instructions are explicit: "Domestic partnerships are no longer required to complete Form 8992 or Schedule A (Form 8992). Instead, domestic partnerships must complete Schedule K-2 (Form 1065), Part VI, and Schedule K-3 (Form 1065), Part VI." Through section 1373(a), an S corporation is treated the same way. Only US individuals (Form 1040) and US C corporations (Form 1120) file Form 8992 at their own level.
But the partnership is not transparent for deciding whether the foreign corporation is a CFC in the first place. The very next paragraph carves the determination questions back out:
Paragraph (d)(1) of this section does not apply for purposes of— (i) Determining whether any United States person is a United States shareholder (as defined in section 951(b)); (ii) Determining whether any foreign corporation is a controlled foreign corporation (CFC) (as defined in section 957(a)) ....
— Treas. Reg. §1.958-1(d)(2)
Example — the pass-through, both halves. US corporation USP A and unrelated US individual USP C own 95% and 5% of domestic partnership P; P owns 100% of foreign corporation FC B. Is FC B a CFC? That question is answered treating P as an entity: P owns 100% of FC B and is a US person, so P is a US shareholder and FC B is a CFC. Who files Form 8992? That question is answered treating P as transparent: USP A is treated as owning 95% of FC B and USP C as owning 5%. USP A is a 10% US shareholder, so USP A files its own Form 8992 for its 95% share; USP C, at 5%, is not a US shareholder and has no inclusion. P itself files no Form 8992. The partnership is used to find the CFC, then stepped through to put the inclusion on the right partner.
In plain terms a US partnership or S corporation that owns a CFC does not file Form 8992 — its 10%-or-greater US owners do, on their own returns. But you still use the partnership to decide the foreign company is a CFC. PILOT applies that split automatically: the entity proves the CFC, and the form rides up to the partners who are 10% US shareholders in their own right.
Tested income, tested loss, and why this is "potentially" required
It is worth being precise about what triggers the filing, because it is easy to assume the form is required only when GILTI tax is owed. It is not. The obligation attaches to owning section 958(a) stock of a CFC as a US shareholder — not to ending up with a positive inclusion. The only relief in the regulation is the paragraph (d) exception for a person who owns no section 958(a) stock. So a US shareholder whose CFCs net to a tested loss still files.
Example — net tested loss. USP A is a US shareholder of two CFCs; one has tested income and one has a tested loss, and across the two A's net CFC tested income is zero or negative. A still owns section 958(a) stock of a CFC, so A still files Form 8992 — completing Part I to show the result and stopping there (the instructions direct that if the Part I line is zero or negative, the filer does not complete Part II or the income columns of Schedule A). The filing exists to report the figure, whatever it is.
That is exactly why PILOT treats Form 8992 as Potential rather than asserting it outright. As a matter of law, the filing obligation is real and follows directly from US-shareholder-of-a-CFC status — the status PILOT determines. PILOT surfaces the form as potentially required, and refers it to Professional review, because the form's substance is the GILTI computation, and PILOT determines what must be filed without performing that computation. Whether a positive inclusion exists, which parts of the form get completed, and how much tax results are all downstream of numbers PILOT does not touch. The flag is firm; the figure is the Professional's.
What OBBBA changed for GILTI (tax years beginning after 2025)
The year matters, and for GILTI it matters a great deal. The 2025 reconciliation act — the One Big Beautiful Bill Act (OBBBA, Pub. L. 119-21) — overhauled the regime for tax years beginning after December 31, 2025. Tax-year-2025 returns still use the rules above; 2026 and later returns use a meaningfully different set. Four changes stand out:
GILTI is renamed "net CFC tested income" (NCTI). OBBBA §70323 substituted "net CFC tested income" for "global intangible low-taxed income" throughout the statute, including the heading of §951A. The acronym GILTI is on its way out of the Code; the inclusion itself remains.
The QBAI carve-out is repealed. Under prior law the inclusion was reduced by a net deemed tangible income return — broadly, 10% of the CFCs' qualified business asset investment. OBBBA struck that reduction. For 2026 and later, the inclusion is computed on the full net tested income, with no reduction for a routine return on tangible assets — a broader base, and the change that most often raises the number.
The §250 deduction drops from 50% to 40%. The deduction a C corporation takes against the inclusion (computed on Form 8993) was 50% under the 2017 Act and was scheduled to fall to 37.5% for 2026. OBBBA §70321 set it at 40% instead (and renamed the companion FDII deduction's base "foreign-derived deduction eligible income," at 33.34%):
there shall be allowed as a deduction an amount equal to the sum of— (A) 33.34 percent of the foreign-derived deduction eligible income ... plus (B) 40 percent of— (i) the net CFC tested income amount (if any) ....
— IRC §250(a)(1)
At a 21% corporate rate, a 40% deduction produces a 12.6% effective rate on the inclusion before credits, up from 10.5%.
The §960(d) foreign tax credit rises from 80% to 90%. OBBBA §70312 increased the share of the CFCs' foreign income taxes a C corporation is deemed to have paid on the inclusion:
if any amount is includible in the gross income of a domestic corporation under section 951A, such domestic corporation shall be deemed to have paid foreign income taxes equal to 90 percent of the product of—
— IRC §960(d)(1)
The higher credit partly offsets the broader base for CFCs that already bear foreign tax.
Example — the same CFC, before and after. FC B is a CFC with steady tested income and a substantial investment in plant and equipment (QBAI). For TY2025, FC B's US corporate shareholder reduces the inclusion by the 10%-of-QBAI net deemed tangible income return, takes a 50% §250 deduction, and claims an 80% deemed-paid credit. For TY2026, the QBAI reduction is gone (the inclusion is computed on all of the net tested income), the §250 deduction is 40%, and the credit is 90%. Same corporation, same earnings — a larger inclusion and a smaller deduction, cushioned for high-foreign-tax CFCs by the larger credit. The direction of each lever is settled; the resulting number is a computation for the Professional, and PILOT does not produce it.
In plain terms for 2026 onward, GILTI has a new name (net CFC tested income), a wider net (no more carve-out for a normal return on equipment), a smaller deduction (40% instead of 50%), and a bigger foreign tax credit (90%). A structure you analyzed for 2025 can produce a very different result for 2026. What does not change is who has to file: a 10%-or-greater US shareholder of a CFC. PILOT flags that the same way in either year — it is the computation behind the form, not the trigger, that OBBBA rewrote.
The GILTI ecosystem — the forms that travel with Form 8992
Form 8992 rarely files alone. The forms it travels with show where the determination ends and the computation begins:
- Form 5471 — the CFC information return. Any US shareholder filing Form 8992 is, by definition, a US shareholder of a CFC, so a Form 5471 obligation is almost always present too. This one PILOT determines (it is a Required-tier filing); Form 8992 is the GILTI computation that builds on the same facts.
- Form 8993 — the §250 deduction. A C corporation claims the 40% deduction on Form 8993 (also a Potential-tier form in PILOT — the deduction is a computation). An individual generally cannot take it without a §962 election.
- Form 1118 — the foreign tax credit. The §960(d) deemed-paid credit on the inclusion is claimed in the §904 "net CFC tested income" basket on Form 1118 (corporations).
- The §962 election and the high-tax exclusion. A US individual may elect under §962 to be taxed on the inclusion at corporate rates and to claim the §960(d) credit — which is how an individual reaches the 40% deduction and the foreign tax credit that are otherwise corporate-only. Separately, a high-tax exclusion can remove a CFC's highly taxed tested income from the calculation entirely. Both are elective planning decisions that turn on computed effective rates; both are out of PILOT's scope, surfaced only as items for the Professional to evaluate, never analyzed or computed.
How Form 8992 is filed, and the penalties
Form 8992 is attached to the US shareholder's income tax return — Form 1040 or Form 1120 — and filed by that return's due date, including extensions. It is not a standalone filing. But "attached to the return" does not mean it carries no penalty of its own, and this is where Form 8992 differs from the other computational forms. It is filed under section 6038 — the same information-return regime as Form 5471 — and the regulation applies that regime's penalties:
If any person required to file Form 8992 (or successor form) under section 6038 and this section fails to furnish the information prescribed on Form 8992 within the time prescribed by paragraph (b) of this section, the penalties imposed by section 6038(b) and (c) apply.
— Treas. Reg. §1.6038-5(c)(1)
That means a failure draws the §6038(b)(1) penalty of $10,000 for each CFC annual accounting period, an additional $10,000 per 30-day period if the failure continues more than 90 days after IRS notice (capped at $50,000 per failure), and a §6038(c) reduction of the foreign tax credit. The Form 8992 instructions confirm it plainly: "Penalties under sections 6038(b) and (c) may apply for failure to report the information required on this form." A reasonable-cause showing, and a substantial-compliance carve-out for an incomplete-but-good-faith filing, can relieve the penalty.
In plain terms Form 8992 looks like a computation that just rides along on the return, but it is a section 6038 information return with real teeth — the same $10,000-per-CFC penalty as Form 5471. This sets it apart from its Potential-tier neighbors: Form 8993 (the deduction), Form 8990 (the interest limitation), and Form 8991 (BEAT) carry no separate information-return penalty of their own. Treat a missed Form 8992 like a missed Form 5471, not like a missed worksheet.
What PILOT does and does not do here
This is the boundary the whole guide turns on, stated plainly. PILOT flags whether Form 8992 is potentially required — and it can, because the trigger is a status it determines: a 10%-or-greater US shareholder of a CFC owning section 958(a) stock, the same finding behind Form 5471. PILOT does not compute the GILTI / net CFC tested income inclusion, the §250 deduction, the §960(d) foreign tax credit, or the resulting tax. It does not decide whether a §962 election or a high-tax exclusion is worthwhile. Those are computations and elections that belong to the Professional and to the engagement's workpapers. PILOT's output names the form, identifies the filer, and cites the status that makes it potentially required — and stops there, on purpose.
In plain terms PILOT's answer is "a US shareholder of a CFC is here, so Form 8992 is potentially required — confirm and compute it." It will never tell you the inclusion amount or the tax. That is not a limitation to apologize for; it is the line between determining what must be filed and computing what is owed, and PILOT stays on the determination side of it.
Relationships to other regimes and forms
Form 8992 sits inside the broader anti-deferral and foreign-corporation rules, and a few neighbors decide how it interacts:
- Subpart F (§951(a)). GILTI / net CFC tested income is the companion to Subpart F. A CFC's Subpart F income is taxed currently under §951(a) and is excluded from tested income, so it never reaches Form 8992; the two regimes divide the CFC's earnings between them. Both ride on the same CFC and US-shareholder determination.
- The CFC determination is the prerequisite. Everything here depends on the foreign corporation being a CFC and the US person being a 10% US shareholder. Those mechanics — the 10% test, the more-than-50% test, and the §958 attribution that drives both, including the OBBBA restoration of §958(b)(4) for tax years beginning after 2025 — are worked in the companion guide, Who must file Form 5471, and what category applies?. Because the §958(b)(4) restoration can switch off CFC status for some foreign-controlled corporations in 2026, it can also switch off the Form 8992 question for those structures — another reason the analysis is year-dependent.
- PFIC overlap (§1297(d)). While a US person is a 10% US shareholder of a CFC, that corporation is generally not also treated as a PFIC as to that person, so the CFC regime (including Form 8992) governs rather than Form 8621. But a sub-10% US owner — the 5% partner in the example above — gets no such overlap relief and can have a Form 8621 obligation even though they have no Form 8992 inclusion. Ruling someone out of GILTI does not rule them out of PFIC reporting.
- Schedule K-2 / K-3. When a domestic partnership or S corporation owns the CFC, the tested income, QBAI, and related figures travel to the partners on Schedule K-2 / K-3, Part VI, and the partner — not the entity — files any Form 8992. A foreign partnership in the chain can also bring Form 8865 into the picture.
What Form 8992 is not
Form 8992 is not a tax-planning document, and it is not a standalone return. It reports a computation — it does not, by itself, minimize your client's tax, and the elections that change the result (the §962 election, the high-tax exclusion, the choice of how to source and credit foreign taxes) are separate, downstream work that builds on the facts the determination captures. It is also not optional for a US shareholder of a CFC who owns section 958(a) stock: the obligation attaches to that status whether or not any tax is ultimately due. The first question — the one this guide answers, and the one PILOT flags — is simply whether a Form 8992 obligation is potentially in play: whether there is a US shareholder of a CFC in the structure, for whom, and for which year.
