While you may not recognize it by name, Form 5471 is an essential filing requirement for many US citizens and permanent residents with ownership in a foreign corporation. Whether you own and operate a foreign-registered business or simply hold an interest in one, you may need to file Form 5471. But what is Form 5471, exactly, and what does it consist of?
Below, we’ll review Form 5471, describing how to file it, who needs to do so, and why it matters, what happens if you don’t, and more.
What Is Form 5471 for US Expats?
Form 5471, formally known as the Information Return of US Persons With Respect to Certain Foreign Corporations, is a mandatory tax form for Americans with certain kinds of interest in foreign businesses.
But what is the purpose of Form 5471?
For one, it gives the IRS visibility into US-owned foreign corporations, including:
- who’s affiliated with them
- what members’ relationship to the business is
- how much income they earn
- loans and other transactions with related parties, and more.
This information helps the IRS detect tax irregularities and enforce anti-tax deferral rules, particularly when it comes to Subpart F income and Global Intangible Low-Taxed Income (GILTI).
Note
As of the OBBB tax bill passed on July 4th, 2025, Congress changed the name of GILTI to “Net CFC Tested Income”. That said, the name change isn’t widely known, and no one, not even in Congress, has come up with a new acronym for it yet.
Given the importance of this form, the IRS levies penalties on those who fail to file the form when required, which we’ll discuss in more detail in a bit.

But first, what is a Controlled Foreign Corporation?
A Controlled Foreign Corporation (“CFC”) is a corporation registered and operating in a foreign country that meets the two-pronged test, which focuses on Control and U.S. Persons.
- more than 50% of the company shares OR more than 50% of the company’s voting power is owned by U.S. shareholders, with each holding a stake of at least 10%.
A “U.S. Person” here can refer to an individual, a corporation, or a resident alien (non-Citizen living in the US for extended periods of time). In order to be considered a U.S. Person, your ownership must be 10% or more.
If this is confusing to you, don’t worry, it’s confusing subject matter! Let’s look at an example to help clarify: Imagine that there are five unrelated shareholders: A, B, C, D, and E. A, B, and C are U.S. Citizens – D and E are not. A owns 20%, B owns 25%, C owns 9%, D owns 25%, and E owns 21%. The US Citizens (A, B, and C) own a total of 54%. However, because C does not own 10% or more of shares, she is not considered a US Person. And therefore, only 45% of the foreign corporation’s shares are owned or controlled by U.S. Persons. This entity is not a CFC — and we exist to help you manage this kind of complexity!

Who Must File Form 5471?
5471 Category Filers Explained
There are several scenarios in which a person may be required to file. So the IRS has established five categories of filers: (1)
Category 1
US shareholders who own a Specified Foreign Corporation (SFC). SFCs are defined as either:
- Controlled Foreign Corporations, or CFCs (see definition above), OR
- Foreign corporations with at least one US shareholder who holds 10% or more of the organization
Category 2
American officers or directors of foreign corporations who own at least 10% or more of the organization
Category 3
- US persons who, over the course of the tax year:
-Acquire at least 10% of a foreign corporation (e.g., from 15% to 25% ownership; but also from 0% to 100% ownership)
-Dispose of enough stock in a foreign corporation that their ownership decreases by 10% (e.g., from 25% to 15% ownership; or 100% to 0% ownership)
Note: Those who become a US person over the course of the tax year while owning at least 10% of a foreign corporation (in other words, a non-Citizen has 35% ownership at all times, then becomes a GreenCard Holder on September 16, 2025. He/she would be a Category 3 Filer).
Category 4
A US person who owned more than 50% of a foreign corporation
Category 5
A US person who owns at least 10% of a CFC and owns stock on the last day of the tax year
What Does Form 5471 Require You to Report?
To be frank, Form 5471 can be complex and time-consuming. However, it is possible to complete it via the following step-by-step Form 5471 instructions.
Top Section
First among the Form 5471 filing requirements is some basic information about yourself, including your:
- Name
- Address
- Filing category
- Address
- Tax number — usually a Social Security Number (SSN) for personal returns and an Employer Identification Number (EIN) for business returns
Then, you’ll share information about the foreign corporation. This includes basic information like the name, address, and country in which it’s based, as well as details like its:
- Date of incorporation
- Business activity code
- Taxable US income
- US tax liability
- Currency
Schedule A: Stock of the Foreign Corporation
In this part of the form, you’ll describe the different classes of stock you offer and how much was issued/outstanding at both the beginning and end of the tax year.

Schedule B: Shareholders of Foreign Corporation
Part I: US Shareholders of Foreign Corporation
Part I of Schedule B is for US shareholders who own at least 10% of a foreign corporation. This refers to any U.S. Shareholders who may own shares directly or indirectly. This captures all the ultimate beneficial owners of the company, even if there are several intermediary companies (i.e., trusts, holding companies, etc.) in between.
In it, they must share some basic information about themselves (name, address, identifying number), the stock they held at the beginning and end of the tax year, and their share of the foreign corporation’s income. More on that in a bit.
Part II: Direct Shareholders of Foreign Corporation
Part II of Schedule B, on the other hand, is for all direct shareholders of a foreign corporation, regardless of whether they are US tax residents and how much stock they hold.
Schedule C: Income Statement
Schedule C requires you to share detailed financial information of the foreign corporation, with different sections for:
- Income
- Deductions
- Net income
- Other comprehensive income
Note that you’ll have to report this information in both the functional currency (i.e., the currency you regularly do business in) and US dollars.
Pro tip: The simplest and quickest way to convert figures from your functional currency into US dollars is typically multiplying them by the IRS’s yearly average currency exchange rates.
Schedule F: Balance Sheet
Schedule F is where you’ll share a balance sheet of your assets and liabilities/shareholders’ equity at both the beginning of the end of the year.
In this section, you’ll report values in US dollars only unless you qualify for the Dollar Approximate Separate Transactions Method (DASTM), which typically only applies to foreign businesses that use a hyperinflationary local currency. (3)
Schedule G: Other Information
Finally, Schedule G will ask you a series of “yes or no” questions about your foreign corporation, covering topics like ownership, income, assets, and transactions.
Subpart F Income and GILTI: What You Need to Know
Now that we’ve reviewed the different components of Form 5471, let’s dig in further to a couple of key concepts.
Subpart F Income
Earlier, we mentioned that those required to complete Part I of Schedule B must use that section to report their Subpart F income.
But what is Subpart F Income on Form 5471, exactly?
The term refers to certain types of income that come from foreign corporations and are taxable even if shareholders don’t receive a direct distribution. This effectively eliminates US shareholders’ ability to indefinitely defer taxes on CFC income. (4)
Subpart F income is usually passive or easily movable, and might include:
- Foreign personal holding company income (e.g., interest, dividends, rents, royalties)
- Foreign base company income (e.g, income from sales or services)
- Income earned from insuring risks outside of the CFC’s home country
There are exceptions to Subpart F income, however, particularly when the income the foreign corporation earns requires a degree of active work.
Example: Dana, a US expat, owns a Controlled Foreign Corporation (CFC) registered in Italy. Through her CFC, she bought a seaside cottage and rents it out to vacationers. This year, all of the rental income stayed in the CFC’s foreign bank account to save for another property. She was hoping that, because she formed a non-US company to shelter this income, the rental profits would not be subject to US taxes.
Even though none of the rental income went to Dana’s personal accounts, it may still qualify as taxable Subpart F income.
However, she may be able to avoid taxation on this income by demonstrating that the rental income qualifies for an active rental exception.
Or she can demonstrate that the CFC paid Italian taxes on that income, and therefore claim a Foreign Tax Credit or a High-Tax Exception.
GILTI and Form 5471 for US Business Owners
Global Intangible Low-Taxed Income, or GILTI, is the portion of a CFC’s tested (read as: net) income that exceeds 10% of its tangible (read as: net fixed) assets.
GILTI is a tax at the shareholder level, meaning that the US shareholder is responsible for paying the tax. This is why you report GILTI on Form 8992, which adds up your GILTI income or losses from all of your CFCs.
Note: Use it or Lose it. In any given year, you may use tested losses from one CFC to offset tested income in another CFC. However, there is no carryforward of losses.
Through tax year 2025, C corporations can claim the §250 tax deduction, which allows only 50% of their GILTI to be subject to the 21% corporate tax rate. This essentially reduces the rate to 10.5% — a big win for US expats with C corporations. On top of that, CFCs can receive a tax credit for up to 80% on foreign taxes paid.
If you own your CFC directly, you are not eligible for the §250 tax deduction and are subject to individual tax rates (up to 39.6%) instead of the ideal 10.5% tax rate.
However, all hope is not lost.
Individual owners of a CFC are allowed to elect to be treated as a corporate entity and benefit from the additional deductions. However, the §962 Election requires extensive tax reporting and documentation for seven years. We generally recommend that taxpayers set up a true US corporate structure to simplify this process.
Pending Changes per OBBBA
The recent passage of the 2025 One Big Beautiful Bill Act (OBBBA) will lead to some major changes from 2026 onward, including: (5)
- Renaming GILTI to NCTI (Net CFC Tested Income)
- Eliminating the deduction for fixed assets so all of a CFC’s tested income will qualify as NCTI (vs. the portion that exceeds 10% of its tangible assets)
- Decreasing the deduction so that only 40% of CFCs’ NCTI income is subject to taxation (vs. 50% previously), resulting in an effective tax of 12.6% (vs. 10.5% previously)
- Increasing the credit so that CFCs can claim up to a 90% credit on foreign taxes paid (vs. 80% previously)
When is Form 5471 Required to Be Filed?
Form 5471 is due at the same time as the rest of your US tax return. For Americans abroad, the due date is typically June 15th. However, it’s common to push that deadline back to October 15th by filing an extension. Note that in order to remain technically tax-compliant, the extension must be filed prior to the June 15th deadline.
Penalties for Non-Compliance
Failing to file Form 5471 (a) accurately, (b) on time, or (c) at all can result in a fine of up to $10,000 per missing report per year. (6)
Continued failure to file can result in an additional Form 5471 penalty: taxpayers who haven’t filed within 90 days of an IRS notice may have to pay $10,000 for each 30-day period that passes (up to $50,000).
If the IRS does levy a penalty, though, you may be able to request penalty relief, particularly if you:
- Had reasonable cause not to file on time (e.g., severe illness)
- Were fully tax-compliant over the past three years, and have never incurred a penalty before
- Qualify for statutory exception
Can You E-File Form 5471?
You may be able to e-file Form 5471 through tax software. Or, if your adjusted gross income (AGI) is $84,000 or less, you may be able to use IRS Free File, but not all platforms support the form due to its complexity.
Even if your tax software does offer Form 5471 filing, it’s almost always better to work with a professional who is both familiar with filing the form and providing tax planning services for business owners designed to strengthen your overall global tax position (read: qualify you for as many savings and deductions as possible).
Why We Recommend Working with a Professional Where Form 5471 is Concerned
Inaccurate filings can be subject to hefty financial penalties, and the statute of limitations is seven years, unlike the standard three years.
Special Considerations for US Business Owners Abroad
There are a few things American business owners abroad should keep in mind when it comes to Form 5471 and US expat taxes:
- Business structure can affect how you file: Whether you file Form 5471 with your individual or business tax return largely depends on who is the legal owner and/or ultimate beneficial owner of the foreign corporation. For example:
- An individual who owns foreign company shares via a Single-Member LLC is required to file Form 5471 on his or her individual tax return. Single-Member LLCs are disregarded for tax purposes and NOT eligible for the §250 tax deduction.
- C Corps and S Corps must file it with their business tax return if the corporation itself holds the foreign corporation shares. But S Corps are NOT eligible for the §250 tax deduction.
- All CFCs must file: Any foreign corporation that’s more than 50% owned by US persons — each of whom owns at least 10% — qualifies as a CFC. As such, its US shareholders must file Form 5471
- Control Matters: You may think, “What if I own 1% of the stock, and I make any family member who does not have US Citizenship own the 99%? Then we can say the CFC is not controlled by a US Person.” The rules address this via the definition of “Control”. The IRS considers shares owned by close family members (spouses, siblings, children, parents, and grandparents) to be controlled by the related person.
- PFICs cause their own issues: Perhaps a foreign corporation doesn’t fall into any of the CFC Filing Categories. It can still be classified as a Passive Foreign Investment Company (PFIC) and the shareholders would be required to file Form 8621. Even more, the taxes imposed on PFIC shareholders are generally higher than the taxes on GILTI income.
The Best Expat Tax Service for US Business Owners Abroad
There are multiple ways to trigger a Form 5471 requirement. So, Americans with any degree of ownership in any foreign corporation should consider consulting a tax professional to confirm their obligations. When just one instance of Form 5471 non-compliance can result in a $60,000 penalty, you don’t want to operate on assumptions.
