The first time I encountered Form 952 was during a large corporate client’s IRS examination that involved a controlled foreign corporation with significant subpart F income – the revenue agent requested a consent to extend the statute, and my client’s in-house team had never heard of it. Getting that form properly executed under time pressure while managing the broader examination strategy is an experience I have since built into my international engagement SOPs as a standard alert trigger.
Key Takeaways
- Form 952 is a consent agreement used to fix the period during which the IRS may assess additional income taxes – it is specifically used in connection with controlled foreign corporation (CFC) examinations and the application of subpart F income rules.
- The form is filed by the U.S. shareholder of a CFC or the domestic corporation with ownership interests being examined, not by the foreign entity itself.
- Like Form 921-A, signing is voluntary – refusal typically results in the IRS issuing a notice of deficiency to preserve its assessment rights before the statute expires.
- Form 952 is distinct from other statute consent forms in that it specifically addresses the assessment limitation period in the international CFC context, often tying to Form 5471 filing issues.
- Quick rule you can copy into your SOP: any client with CFC ownership and an active IRS examination should have a statute of limitations tracking log that includes all open years, Form 5471 filing positions, and any outstanding consent requests.
- Failure to manage the CFC statute carefully can result in assessment exposure for multiple years simultaneously if the IRS pursues a broad examination of subpart F inclusions, GILTI, or transfer pricing.
What Form 952 Is and When to Use It
Form 952 – Consent to Fix Period of Limitation on Assessment of Income Taxes – is an agreement between a U.S. taxpayer and the IRS that extends the normal statute of limitations on income tax assessments to a specific agreed date. It functions similarly to Form 921-A, but its primary application is in the context of international tax examinations involving controlled foreign corporations, subpart F income, global intangible low-taxed income (GILTI), and related cross-border structures.
Form 952 surfaces most often when the IRS is examining a U.S. parent corporation’s Form 5471 (Information Return of U.S. Persons With Respect to Certain Foreign Corporations) or related international tax positions. The examination of CFC structures is inherently complex – it often involves multiple tax years, intercompany transactions, foreign tax credit calculations, and Subpart F inclusion computations – and the IRS frequently needs more time than the standard three-year window to complete its review.
The decision to sign Form 952 in an international tax context carries the same strategic weight as any other statute extension consent, but the stakes are often higher given the potential for large proposed adjustments involving transfer pricing, earnings and profits repatriations, or GILTI computations. My team always involves international tax counsel in these decisions before any consent is executed.
CFC Ownership Structure and Assessment Scope
A controlled foreign corporation is a foreign corporation in which U.S. shareholders (each owning at least 10% of the voting stock) collectively own more than 50% of the stock. Form 952 applies when the IRS is examining the U.S. shareholder’s income inclusion from the CFC – typically subpart F income under IRC §§951–965 or GILTI under IRC §951A. The form fixes the period during which additional tax resulting from these inclusions may be assessed against the U.S. shareholder.
Relationship to Form 5471
Form 5471 is the annual information return filed by U.S. persons with interests in CFCs. Errors or omissions on Form 5471 can trigger extended statutes of limitations under IRC §6501(c)(8), which suspends the normal limitations period until the required information is provided. Form 952 may be used in conjunction with resolving Form 5471 filing issues when the IRS and the taxpayer need additional time to reconcile the CFC’s earnings and profits, taxes paid, and income inclusions.
How to Complete Form 952
Form 952 is a concise document, but each element is legally significant. The form captures the U.S. taxpayer’s identity, the CFC’s identity, the tax years covered, and the agreed fixed assessment date. Errors in any of these fields can compromise the consent’s validity.
| Field / Section | What to Provide | Practitioner Tip |
|---|---|---|
| U.S. Taxpayer Name | Full legal name of the U.S. shareholder or domestic corporation | Match exactly to the Form 5471 and the domestic tax return for the year under examination |
| U.S. Taxpayer EIN / SSN | Employer identification number or social security number | Cross-check against the most recently filed return – a transposed digit invalidates the consent |
| CFC Name and Country | Legal name of the controlled foreign corporation and its country of organization | Use the legal name as it appears on the CFC’s formation documents, not a nickname or abbreviation |
| Tax Year(s) Covered | Specific U.S. tax year(s) to which the consent applies | CFC examinations often span multiple years – list every year explicitly; do not assume a range is implicit |
| Fixed Assessment Date | The exact date through which the IRS may assess additional income taxes | Negotiate this date strategically; document the negotiation in the engagement file |
| U.S. Taxpayer Signature | Authorized officer or representative signature with date | Verify POA authority; Form 2848 must explicitly cover statute of limitations consents in international contexts |
| IRS Authorized Signature | Territory manager or group manager countersignature | Consent is not effective until both parties sign; do not treat a taxpayer-only signed form as protective |
Scope Limitations in the CFC Context
In CFC examinations, practitioners sometimes negotiate Form 952 consents that limit the scope to specific issues – for example, the subpart F income calculation for a particular subsidiary, rather than all income tax issues for the year. This approach can focus the examination and prevent the IRS from expanding into unrelated domestic issues under the broader statute window. Always document any scope limitations explicitly in the consent language.
Deadlines, Penalties, and Filing Requirements
Form 952 has no independent filing deadline – it is executed reactively when an open CFC examination approaches the end of the normal assessment period. The urgency is driven by the IRC §6501 limitations clock and, in some cases, the extended limitations periods triggered by incomplete Form 5471 filings.
| Limitations Scenario | Applicable Period | Notes |
|---|---|---|
| Standard domestic return with CFC income | 3 years from filing or due date (later of the two) | Normal IRC §6501(a) period applies to the U.S. shareholder return |
| Omission of >25% of gross income | 6 years | Can apply where CFC subpart F inclusions were omitted from the U.S. return |
| Failure to file Form 5471 (required CFC information return) | Suspended – period does not run until Form 5471 is filed | IRC §6501(c)(8); one of the most significant statute traps in international practice |
| Fraudulent return or no return filed | No limitation | Assessment may occur at any time; Form 952 not applicable |
The Form 5471 Statute Trap
One of the most important – and most often overlooked – statute issues in the CFC context is IRC §6501(c)(8). If a required Form 5471 is not filed or is filed incompletely, the entire statute of limitations for the U.S. shareholder’s return is suspended, not just the portion related to the CFC. This means the IRS can assess additional taxes on any item on the return, not just CFC-related items, until the Form 5471 filing requirement is satisfied. Small errors create big cleanup in the international space.
CFC Examination Strategy – Managing Form 952 Decisions
CFC examinations are among the most technically complex in the IRS’s international enforcement portfolio. Managing Form 952 consent decisions within this context requires integrating statute strategy with the broader examination defense approach.
Transfer Pricing and the Extended Examination Timeline
Transfer pricing examinations involving CFCs frequently extend well beyond the normal three-year period simply because the factual and economic analysis required is substantial. IRS International Examiners often request Form 952 consents early in a transfer pricing examination to ensure they have adequate time to complete their analysis. My general guidance is to negotiate the shortest fixed period that gives the examination a reasonable chance to close – and to insist on a defined issue scope rather than a blanket consent across all issues.
Coordinating with Foreign Tax Authorities
CFC examinations sometimes run parallel to foreign tax authority inquiries in the CFC’s country of organization. In these situations, Form 952 consent decisions should be coordinated with the analysis of any applicable tax treaty provisions, mutual agreement procedures (MAPs), and the risk of double taxation from inconsistent adjustments in multiple jurisdictions. Involve your client’s international tax counsel early to map these interactions.
International Filing Context – Form 952 in the Broader Compliance Picture
Form 952 does not exist in isolation – it is part of a web of international tax compliance obligations that firms serving multinational clients must navigate. Understanding where Form 952 fits helps practitioners anticipate when it may arise and prepare clients accordingly.
Key International Forms That Intersect With Form 952
Form 5471 (CFC information return), Form 8992 (GILTI calculation), Form 8993 (FDII deduction), Form 1118 (foreign tax credit), and the associated earnings and profits schedules all create the factual record that IRS international examiners review. Errors or inconsistencies in any of these forms can prompt the examination that triggers a Form 952 request. A clean, well-documented international compliance package is the best protection against a contentious CFC examination.
GILTI and Post-TCJA Examination Activity
Since the Tax Cuts and Jobs Act introduced GILTI under IRC §951A in 2017, the IRS has significantly increased examination activity around CFC structures. GILTI computations involve tested income, tested loss, qualified business asset investment (QBAI), and net deemed tangible income return (NDTIR) – all of which require detailed foreign financial data. Examinations of these positions are time-intensive, making Form 952 consent requests more common in the post-TCJA environment than they were historically.
Common Mistakes That Slow Things Down
- Signing without checking POA authority for international matters – verify that the Form 2848 on file explicitly covers statute extensions in the context of CFC examinations.
- Not tracking the Form 5471 statute trap – if a required Form 5471 was not filed or was incomplete, the statute is suspended for the entire return, not just CFC issues; identify and cure this before any consent negotiation.
- Accepting an unlimited-scope consent – negotiate scope limitations that restrict the consent to the CFC-related issues under examination; blanket consents open the door to unrelated domestic audit issues.
- Failing to involve international tax counsel – Form 952 decisions in complex CFC examinations are strategic choices with significant financial consequences; treat them that way from the start.
- Not calendaring the fixed expiration date immediately – set a 90-day advance reminder for every Form 952 expiration date across your client portfolio.
- Missing the countersignature – a taxpayer-only signed Form 952 provides no protection; confirm IRS countersignature and retain a complete copy in the engagement file.
- Treating multiple CFC years as covered by a single consent – each tax year must be explicitly named; a consent that lists only one year does not protect the IRS’s right to assess in other open years.

For Accounting Firms – Keep Delivery Smooth While You Scale
International tax compliance – including CFC monitoring, Form 5471 preparation, and GILTI calculations – is one of the highest-complexity areas in any firm’s practice. Managing these obligations across multiple clients simultaneously requires both technical expertise and robust production infrastructure. Firms that use trained offshore teams for international tax preparation and documentation work often find that their senior international tax practitioners can focus on examination strategy and client advisory rather than form-filling and workpaper assembly.

FAQs About Form 952
What is the difference between Form 952 and Form 921-A?
Both forms fix the period of limitation on income tax assessments to a specific agreed date. Form 921-A has a broader application across income and profits tax examinations, while Form 952 is specifically used in the context of controlled foreign corporation examinations and related international tax issues. In practice, the IRS may use either form depending on the specific examination context – confirm with the revenue agent which form applies to your client’s situation.
Can the IRS assess tax on domestic issues during the Form 952 extended period?
It depends on the scope of the consent. If Form 952 is signed without scope limitations, the extended period technically covers all income tax assessments for the year, not just CFC-related items. This is why negotiating limited-scope language is important in CFC examinations – a well-drafted consent can restrict the IRS to the CFC issues that triggered the examination.
What happens if Form 5471 was not filed for an open year?
Under IRC §6501(c)(8), the failure to file a required Form 5471 suspends the entire statute of limitations for the U.S. shareholder’s return – not just the CFC-related portion. The statute does not begin to run until the Form 5471 is filed. If this situation exists in your client’s file, resolving the Form 5471 filing issue is the first priority before any statute consent negotiation.
How does GILTI affect Form 952 exposure?
GILTI computations depend on the CFC’s tested income, QBAI, and other variables that require detailed foreign financial records. IRS examinations of GILTI positions are factually intensive, and revenue agents often request Form 952 consents to allow adequate time to complete their review. The higher the GILTI inclusion amounts at stake, the more strategic the Form 952 signing decision becomes.
Is Form 952 filed with the tax return?
No. Form 952 is an agreement executed between the taxpayer and the IRS during an open examination – it is not a return attachment. It is typically exchanged directly with the revenue agent or examination team and does not pass through normal return processing channels. Retain the fully executed (countersigned) original in the client engagement file.
