A Practical Guide for Expats and US Persons Abroad (2025 Edition)
Most Americans abroad eventually ask this question:
“I own a foreign company, do I need to file Form 5471, and will the IRS tax me on the profits?”
This article breaks it down in a clean, practical way with examples you can actually understand.
Why the IRS Requires Reporting of Foreign Companies
The US is one of the only countries that taxes citizens and residents on their worldwide income, regardless of where they live.
A foreign corporation, however, is generally not taxed by the US on its foreign income. Before today’s anti-deferral rules existed, it was common for a US person to:
- set up a company in a low-tax country
- place investments or intellectual property inside it
- allow income to grow offshore tax-deferred
- avoid US tax unless the company eventually paid a dividend
To prevent this, the US created Subpart F, a system that taxes certain types of income earned by a foreign corporation even when profits are not distributed.
Form 5471 is the form the IRS uses to track foreign corporations owned by US persons and determine if Subpart F or GILTI applies.
Do You Owe US Tax on a Foreign Company’s Profits?
Not always.
There are five Form 5471 filing categories, but only Category 5 may result in US taxation of a foreign corporation’s undistributed profits.
Category 5 = CFC = potential Subpart F or GILTI income
Not a CFC = generally no Subpart F or GILTI
Categories 2, 3, and 4 may still require filing Form 5471, but they are informational, not income-generating.
What Is a Controlled Foreign Corporation (CFC)?
A foreign corporation is a CFC if both are true:
- US shareholders (each owning at least 10%) collectively own more than 50%, and
- A “US shareholder” is a US person who owns 10% or more of vote or value (directly, indirectly, or constructively).
Example 1: Foreign Company Not Classified as a CFC
A corporation has 10 unrelated owners:
- 9 US persons each own 8% (total 72%)
- 1 nonresident owns 28%
None owns at least 10%, so there are no US shareholders under the CFC rules.
Result:
- not a CFC
- no Category 5
- no Subpart F or GILTI
- other categories may still apply (informational only)
Example 2: Foreign Company That Is a CFC
A US person owns 65% of a foreign corporation.
That person owns at least 10%, and US shareholders own more than 50% → the corporation is a CFC → Category 5 applies.
US Tax Consequences When a Foreign Company Is a CFC (Category 5 Filing)
If a foreign corporation is a CFC, the US may require certain types of income to be reported by the US shareholder even when the company does not make a distribution.
There are two main regimes:
1. Subpart F Income (passive income)
Certain types of income, such as interest, dividends, rents, or royalties, may be taxed immediately to US shareholders. These rules were designed to prevent shifting passive income into low-tax jurisdictions.
2. GILTI (active business income)
Active business profits may be included under the GILTI rules unless an exception applies (including the high-tax exception). For many expats operating real businesses abroad, GILTI can apply only if the effective foreign tax rate is low enough.
3. No double taxation on previously taxed profits (PTEP)
If the US taxes income under Subpart F or GILTI in a given year, that income becomes Previously Taxed Earnings (PTEP).
Later dividends paid out of PTEP are generally not taxed again by the US, preventing double taxation.
High-Tax Exception for Foreign Corporations
If a CFC pays foreign income tax above 18.9%, certain Subpart F or GILTI items may qualify for “high-tax” treatment.
This can reduce or eliminate US income inclusion. However, Form 5471 Category 5 must still be filed.
Note: Subpart F and GILTI high-tax relief exist under separate elections, but both operate on the same principle — income that is sufficiently taxed abroad is often excluded from current US taxation.
Example: UK company taxed at 19%
The UK standard corporate tax rate is 19%.
This generally meets the high-tax threshold, so:
- Category 5 filing still required
- In many cases, no Subpart F or GILTI inclusion
Form 5471 Filing Requirements for Non-CFC Foreign Corporations
A foreign corporation may not be a CFC, but a US person may still need to file Form 5471 under:
- Category 2 – Officer/director reporting
- Category 3 – Acquisitions/dispositions crossing 10%
- Category 4 – Control (>50% vote or value)
These categories are informational only.
Category 2 — US Officers or Directors of Foreign Corporations
Category 2 applies when a US person who serves as an officer or director of a foreign corporation must report the event where another US person acquires 10 percent or more of the corporation’s stock.
Category 2 depends on your role (officer/director), not on your ownership percentage.
Category 3 — Reaching or Dropping Below the 10 Percent Ownership Rule
Category 3 applies when a US person:
- acquires enough stock to reach 10%, or
- disposes of stock causing ownership to fall below 10%
Category 4 — Foreign Corporation Control Test (Over 50 Percent)
Category 4 applies when a US person owns more than 50% of the corporation for at least 30 days.
If a US person falls into Categories 2, 3, or 4 — but not Category 5 — the Form 5471 filing is purely informational. No Subpart F or GILTI income is calculated and no US tax is owed on the corporation’s undistributed profits.
How Are Foreign Company Ownership Percentages Calculated? (Attribution Rules Explained)
The IRS uses attribution rules that treat a US person as owning stock held by certain relatives or entities.
There are two different attribution systems:
- CFC status (Category 5) → IRC §958 (narrow rules)
- Categories 2, 3, 4 → §§6038, 6046, 318 (broader rules)
These systems can produce different results from the same facts.
Attribution for CFC Status (Category 5)
CFC rules attribute ownership only from:
- spouse
- parents
- children
- grandchildren
These rules determine whether a corporation is a CFC and whether Subpart F or GILTI may apply.
Attribution for Categories 2, 3, and 4
Categories 2–4 use broader attribution rules under §§6038 and 6046. These rules attribute shares from:
- spouse
- siblings
- ancestors
- lineal descendants
- certain entities
Important:
These rules also attribute shares from foreign family member that fall within these specific categories.
Example: Different Attribution Tests Produce Different Outcomes
A US person owns 30%.
A nonresident sibling owns 40%.
- CFC test (Category 5): sibling attribution does not apply → not a CFC
- Category 4 test: sibling attribution does apply → treated as 70% → Category 4 applies
Category 4 does not trigger Subpart F or GILTI.
US Tax Reporting When Married to a Nonresident Alien (NRA) Spouse
When a US person is married to a nonresident-alien (NRA) spouse, the attribution rules can produce filing categories that look counterintuitive.
For CFC purposes (Category 5), the NRA spouse’s stock is not attributed to the US spouse.
But for Categories 2, 3, and 4, the broader attribution rules under sections 6038 and 6046 do attribute the NRA spouse’s ownership to the US person.
This means:
- A corporation might not be a CFC (no Category 5),
- But the US spouse may still be treated as owning more than 50% (Category 4),
- And may trigger Category 2 or Category 3 in the formation year,
- Even when they own only a small direct percentage.
Because of these mixed attribution rules, a single foreign corporation can cause multiple Form 5471 categories to apply at the same time.
Category 4 has a special exception: If a US person has no direct or indirect ownership in a foreign corporation, and their Category 4 status arises solely due to attribution from a nonresident-alien (NRA) spouse, then no annual Category 4 filing is required (Treas. Reg. §1.6038-2(l)). This exception does not apply when the US person owns even a small direct interest (such as 1%). In those cases, full Category 4 applies.
The following examples illustrate the most common situations.
Scenario 1 — US Person Owns 1%, Nonresident Spouse (NRA) Owns 99%
Facts:
- US person directly owns 1% of the foreign corporation and serves as an officer
- Nonresident-alien spouse owns 99%
- No community property rules apply
- Corporation was formed during the tax year
Outcome:
- Category 5 (CFC):
NRA spouse stock is not attributed under §958(b).
US shareholders directly own only 1% → not a CFC → no Category 5. - Category 4 (control):
Under §6046 attribution, the US person is treated as owning the spouse’s 99%.
For control purposes, the US person is treated as owning 100% → Category 4 applies. - Category 4 Exception:
Does not apply here because the US person has direct ownership (1%). - Category 3:
In the formation year, attribution may cause the US person to cross the 10% threshold → Category 3 applies in the first year. - Category 2:
Applies only if the US person is an officer or director.
Result:
Not a CFC → no Category 5 → no Subpart F or GILTI
Formation year: Categories 2, 3, and 4
Later years: Category 4 (while ownership remains the same)
Scenario 2 — US Person Owns 51%, Nonresident Spouse Owns 49%
Facts:
- US person owns 51%
- Nonresident-alien spouse owns 49%
- Corporation was formed during the tax year
Outcome:
- Category 5 (CFC):
US shareholders own more than 50%, and the US person owns at least 10% → CFC → Category 5 applies. - Category 4 (control):
The US person directly owns more than 50% → Category 4 applies. - Category 3:
Formation-year acquisition of 51% crosses the 10% threshold → Category 3 applies. - Category 2:
Applies if the US person is an officer or director.
Result:
- Formation year: Categories 2, 3, 4, and 5
- Later years: Categories 4 and 5
- Because this is a CFC, Subpart F or GILTI may apply, reduced or eliminated if the high-tax exception applies
Scenario 3 — US person owns 0%, nonresident spouse owns 100%
Facts:
- US person owns 0% of the foreign corporation
- Nonresident-alien spouse owns 100%
- No community property rules apply
- Corporation was formed during the tax year
Outcome:
- Category 5: Does not apply. CFC status does not attribute stock from an NRA spouse under §958(b), so the corporation is not a CFC.
- Category 4: Technically applies because §6046 attribution treats the US person as owning the NRA spouse’s 100%.
- Category 4 Exception: When the US person has no direct or indirect ownership, and Category 4 applies solely because of attribution from a nonresident spouse, the exception under Treas. Reg. §1.6038-2(l) generally eliminates the annual filing requirement.
- Category 3: In the formation year, the US person is treated as crossing the 10% threshold through attribution. A one-time Category 3 filing may be required.
- Category 2: Applies only if the US person is an officer or director of the corporation.
Result:
- Possible one-time Form 5471 filing in the formation year (Category 3).
- No annual Form 5471 if the Category 4 exception applies.
- Not a CFC → no Category 5 → no Subpart F or GILTI.
Nonresident Spouses and Attribution
- Category 5 (CFC): NRA spouse’s stock is not attributed
- Category 4: spousal attribution applies
- Categories 2–3: broad attribution applies
Four Common Ownership Scenarios (2025 Rules)
| US Person Owns | NRA Spouse Owns | CFC? | Category 4? | Filing Requirement | Subpart F/GILTI? |
|---|---|---|---|---|---|
| 0% | 100% | No | Technically yes, but exempt | Possibly Category 3 (formation year) | No |
| 50% | 50% | No | Yes | Annual Category 4 | No |
| 50.01–100% | 0–49.99% | Yes | Yes | Categories 4 + 5 | Possible |
| 0.01–49.99% | 50.01–99.99% | No | Yes | Annual Category 4 | No |
When Is Form 5471 Due?
Form 5471 is filed with the US tax return.
- April 15, 2026 – Standard deadline
- June 15, 2026 – Automatic extension for US persons abroad
- October 15, 2026 – With Form 4868
- December 15, 2026 – Additional extension upon written request
The IRS may impose penalties of $10,000 per year, per category of failure, if Form 5471 is late, incomplete, or inaccurate — and additional penalties may apply if the failure continues after IRS notice.
Community Property Rules
In community property jurisdictions, marital assets may be treated as 50/50, affecting attribution and filing requirements.
Frequently Asked Questions (FAQ) – Form 5471 and Foreign Corporations
Do I need to file Form 5471 if I own a foreign single-member LLC or a disregarded entity?
Usually no.
A foreign single-member LLC or similar entity is not treated as a corporation for US tax purposes unless it elects corporate status or is automatically classified as a corporation under US rules.
However, if the entity is treated as a foreign disregarded entity, Form 8858 may be required instead. And if the entity elects corporate taxation, Form 5471 may apply.
Does Form 5471 replace Form 8938 or the FBAR?
No. These are separate reporting requirements.
- Form 5471 → reports foreign corporations
- Form 8938 → reports foreign financial assets
- FBAR → reports foreign bank accounts
Form 5471 is an “excepted foreign financial asset” for Form 8938, meaning you do not duplicate the corporation’s details on Form 8938. But you must disclose the number of Forms 5471 filed on Form 8938.
If I am Category 5 and the company had a loss, do I need to pay any US tax?
Generally, no.
If the foreign corporation has no Subpart F income and no GILTI because it had a loss or otherwise no tested income, then there is typically no US tax due, even for Category 5 filers. You must still file Form 5471, but there is no income inclusion when the CFC has no positive earnings under the Subpart F and GILTI rules.
If I fall into Category 5 and there is taxable income, can I claim a foreign tax credit for taxes the company paid?
Foreign taxes paid by the corporation belong to the corporation, not the shareholder, so individuals cannot claim a foreign tax credit.
However, a Section 962 election may help reduce US tax by applying:
- the 21% corporate rate,
- an 80% foreign tax credit, and
- for GILTI only, the 50% deduction (Section 250).
Whether the election is beneficial depends on the specific facts and must be modeled annually.
If I missed filing Form 5471, what can I do?
If the failure was non-willful, options may be available.
The Streamlined Foreign Offshore Procedures can help taxpayers who live abroad correct past omissions while potentially reducing exposure to penalties if accepted.
Other relief options may also apply depending on your facts.
Do I need to file Form 5471 every year?
Yes, if you still meet the ownership or attribution rules for your category.
Category 5 (CFC owners) requires annual filing, even if:
- the company has no activity
- the company paid high foreign tax
- the company had a loss
- no distributions were received
Categories 2, 3, and 4 also require annual filing if the ownership conditions are still met.
Does a foreign corporation with no activity or dormant status require Form 5471?
In certain cases, a reduced filing may be available under Rev. Proc. 92-70, but the corporation must meet strict criteria.
If I close my foreign corporation, do I still need Form 5471?
Usually yes.
The IRS generally requires a final year Form 5471, and additional forms may be required if there was a liquidation or sale of shares.
Can your firm help determine whether I need to file Form 5471?
Absolutely.
We regularly assist expats in determining whether Form 5471 applies and which categories are required.
How much do you charge to file Form 5471?
Form 5471 is not included in any package but can be added at a fixed rate:
- $500 for Category 5 (CFC filings)
- $400 for Category 2, 3, or 4 informational filings
Additional fees may apply if a Section 962 election or other planning is required.
