Form 1120 + Form 5472 for Foreign-Owned C-Corporations
How to file an actual (not pro forma) Form 1120 corporate tax return with Form 5472 when your US corporation has 25%+ foreign ownership. This guide covers regarded entities, not disregarded LLCs.
Key Takeaways
- A US C-Corporation with 25%+ foreign ownership must file Form 5472 with its Form 1120
- The 25% threshold is per individual shareholder, not aggregate foreign ownership
- This is a real Form 1120 with actual tax liability, not a pro forma filing
- Part 4 of Form 5472 reports monetary transactions (unlike DREs that use Part 5)
- Dividends to foreign shareholders trigger 30% withholding (or treaty rate)
Who This Guide Is For
This guide is for US domestic corporations (C-Corporations) where at least one shareholder is a foreign person or entity that owns 25% or more of the total voting power or total value of all classes of stock. If your business is structured as a C-Corporation and has foreign shareholders meeting this threshold, you are required to file Form 5472 alongside your annual Form 1120 corporate income tax return.
This guide does not cover foreign-owned single-member LLCs (disregarded entities), which file a pro forma Form 1120 with Form 5472. If you have a disregarded LLC, see our other guides on that topic.
Understanding the 25% Ownership Threshold
The 25% threshold is measured per individual foreign person, not as an aggregate of all foreign shareholders combined. This is a critical distinction that many people misunderstand.
Triggers Form 5472: A US corporation has 3 shareholders. One foreign individual owns 30% of the stock. Because a single foreign person holds 25% or more, the corporation must file Form 5472 for transactions with that shareholder.
Does NOT trigger Form 5472: A US corporation has 100 shareholders, all foreign, each owning 1% of the stock. Even though 100% of the corporation is foreign-owned in aggregate, no single person meets the 25% threshold. Form 5472 is not required under the 25% ownership rule.
Note that the 25% test considers both direct and indirect ownership. If a foreign person owns 25% of a foreign entity that in turn owns stock in the US corporation, the attribution rules may apply. Consult the Form 5472 instructions for the full attribution rules under Sections 267(c) and 318.
Corporation vs Disregarded Entity
This is one of the most important distinctions in foreign-owned US entity tax filing, and getting it wrong can lead to serious errors.
| Feature | C-Corporation (This Guide) | Disregarded Entity LLC |
|---|---|---|
| Entity type | Corporation (or LLC that elected C-Corp via Form 8832) | Single-member LLC (default classification) |
| Form 1120 type | Actual Form 1120 with real income/expenses | Pro forma Form 1120 (zeros on most lines) |
| Pays its own taxes | Yes, at corporate tax rate (21%) | No, pass-through to owner |
| Form 5472 Part used | Part 4 (monetary transactions) | Part 5 (reportable transactions of DRE) |
| Form 5472 Box 3 | Left blank | Checked (identifies as DRE) |
| Balance sheet required | Yes (Schedule L) | Usually zeros |
| Shareholder distributions | Taxable dividends with withholding | Not taxable distributions |
If your LLC elected C-Corporation status via Form 8832: You are filing a real Form 1120. Your LLC is treated as a corporation for all tax purposes. The C-Corp pays its own income tax at the 21% corporate rate. This is fundamentally different from the pro forma Form 1120 filed by a disregarded entity, which reports no income and no tax.
Three Scenarios Requiring Form 5472
Form 5472 is required in three distinct situations. Each involves a different underlying tax return and different reporting obligations.
Scenario 1: US Domestic Corporation with 25%+ Foreign Ownership
A US-incorporated C-Corporation (or an LLC taxed as a C-Corp) where at least one foreign person owns 25% or more of the stock. Form 5472 is attached to the regular Form 1120 corporate income tax return.
This guide covers this scenarioScenario 2: Foreign Corporation in US Trade or Business
A foreign corporation engaged in a US trade or business that has a 25% foreign shareholder. Form 5472 is attached to Form 1120-F (the US income tax return for foreign corporations). This situation typically arises when a foreign company has a US branch or permanent establishment.
Scenario 3: Foreign-Owned Disregarded Entity (LLC)
A US single-member LLC owned by a foreign person. The LLC files a pro forma Form 1120 (with zeros on most lines) solely as a vehicle to attach Form 5472. This is the most common filing scenario and is covered in our other guides.
Who Is a “Foreign Person”?
For purposes of Form 5472 and the 25% ownership test, a “foreign person” includes any of the following:
Foreign Individual
A person who is not a US citizen, does not hold a US green card (lawful permanent resident), and does not meet the substantial presence test for the tax year in question.
Foreign Corporation
A corporation organized under the laws of a foreign country. This includes foreign parent companies that own shares in a US subsidiary.
Foreign Partnership
A partnership organized under foreign law or one in which 50% or more of the income or capital interests are held by foreign persons.
Foreign Trust or Estate
A trust or estate that does not meet the definition of a domestic trust under Section 7701(a)(30). Generally, a trust is foreign if a US court does not exercise primary supervision over its administration and US persons do not control all substantial decisions.
Important: A person who was a US resident at the beginning of the tax year but moved abroad and terminated their residency during the year may still be considered a foreign person for the portion of the year after the termination date. The 25% test is applied on a yearly basis.
Form 1120 Key Sections for Foreign-Owned Corporations
When a C-Corporation has foreign ownership, certain sections of Form 1120 require particular attention. Below are the areas that are most commonly relevant or where errors frequently occur.
Page 1: Income, Deductions, and Tax Computation
Unlike a pro forma filing for a disregarded entity, this is a real tax return. Report all gross receipts, cost of goods sold, and deductions from actual business operations. The corporation computes its taxable income and pays federal income tax at the 21% corporate rate. Line 30 shows taxable income and Line 31 shows total tax. The corporation must also make estimated tax payments throughout the year if it expects to owe $500 or more.
Schedule K: Other Information
Schedule K contains yes/no questions that are critical for foreign-owned corporations. Pay close attention to:
- Question 4b:Asks whether any individual or estate owns 20% or more of the voting stock. If your foreign shareholder owns 20% or more, answer Yes and provide the details.
- Question 7:Asks whether at any time during the tax year, a foreign person owned 25% or more of the total voting power or value of the corporation's stock. This is the core question that triggers the Form 5472 requirement. Answer Yes.
- Question 10:Total number of shareholders at end of tax year. Report the actual count.
- Question 19:Asks whether the corporation paid dividends or made other distributions to its shareholders during the year. If dividends were paid to foreign shareholders, this triggers withholding obligations under Sections 1441 and 1442 (covered in the Dividend Withholding section below).
Schedule L: Balance Sheet per Books
Schedule L reports the corporation's balance sheet at the beginning and end of the tax year. For foreign-owned corporations, pay particular attention to loans from shareholders. If a foreign shareholder has loaned money to the corporation, this appears as a liability on the balance sheet and must also be reported as a transaction on Form 5472 Part 4. Shareholder loans are one of the most common reportable transactions for foreign-owned C-Corps.
Schedule G: Stock Ownership of Persons Owning 20% or More
List each shareholder who owns 20% or more of the corporation's stock. For each, provide the name, identifying number (SSN, ITIN, or EIN), country of citizenship or organization, and percentage of stock owned. Foreign shareholders without a US tax ID should use their foreign tax identification number or enter “FOREIGNUS” as a placeholder while an ITIN application is pending.
Schedule N: Foreign Operations of US Corporations
If the corporation has foreign operations, income from foreign sources, or makes payments to foreign persons, Schedule N must be completed. This schedule asks about foreign tax credits, Subpart F income, controlled foreign corporation relationships, and other international tax items. For a simple corporation with only foreign ownership (but all operations in the US), many of these questions will be answered No. However, if the foreign shareholder also controls foreign entities that transact with the US corporation, some questions may apply.
Additional Required Forms
Depending on the corporation's circumstances, several additional forms may be required along with Form 1120 and Form 5472.
Form 1125-E: Compensation of Officers
Required if the corporation's total receipts (Line 1a plus Lines 4 through 10 on page 1 of Form 1120) are $500,000 or more. Lists each officer's name, SSN or ITIN, percentage of time devoted to business, percentage of stock owned, and amount of compensation. If the foreign shareholder is also an officer receiving compensation, this creates a reportable transaction on Form 5472 as well.
Form 8858: Information Return for Foreign Disregarded Entities and Foreign Branches
If the US corporation has a foreign branch, or if the foreign shareholder has a physical business presence abroad that relates to the US corporation's operations, Form 8858 may be required. This form reports the activities of foreign disregarded entities and branches of US persons.
Section 351 Statement (First-Year Filing)
When a corporation is first formed and the shareholder transfers cash (or other property) to the corporation in exchange for stock, this is a Section 351 transaction. The transferor must attach a statement to their tax return (and the corporation should attach one to Form 1120) describing the property transferred, the stock received, and confirming that the transaction qualifies for nonrecognition under Section 351. This is especially important in the first year of the corporation's existence.
Forms 1042-S and 1042 (If Dividends Paid)
If the corporation distributes dividends to foreign shareholders, it must withhold tax and report the withholding on Form 1042-S (for each recipient) and Form 1042 (the annual summary). See the Dividend Withholding section below for details.
Form 5472 for Corporations: Part by Part
When filed by a C-Corporation (as opposed to a disregarded entity), Form 5472 uses different parts. Below is a walkthrough of each section as it applies to a US domestic corporation with foreign ownership.
Part 1: Reporting Corporation
Enter the US corporation's identifying information:
- Corporation name and address as it appears on Form 1120
- Employer Identification Number (EIN)
- Principal business activity and NAICS code
- Total assets at end of tax year (from Schedule L)
- Line 1F: Total value of gross payments made TO related parties (from Part 4)
- Line 1H: Total value of gross payments received FROM related parties (from Part 4)
Box 2 and Box 3
Box 2 (Check if applicable): Check this box if the reporting corporation is 50% or more foreign-owned at any time during the tax year. If your foreign shareholder owns 50% or more of the stock, check Box 2.
Box 3: Leave blank. Box 3 is checked only when the filing entity is a foreign-owned US disregarded entity. Since this guide covers C-Corporations (regarded entities), Box 3 should never be checked.
Part 2: 25% Foreign Shareholder
Identify the foreign shareholder that triggers the filing requirement:
- Full legal name of the foreign person or entity
- Address (use the foreign address, not a US mailing address)
- US taxpayer identification number (if any) or foreign TIN
- Unique Reference ID number (you assign this, it must be consistent year to year)
- Country of citizenship, organization, or incorporation
- Percentage of stock owned (voting and value)
If there are multiple foreign shareholders each meeting the 25% threshold, file a separate Form 5472 for each one.
Part 3: Related Party
If the transactions being reported are with a related party other than the 25% shareholder identified in Part 2, provide that party's information here. For example, if the foreign shareholder also controls a foreign corporation that transacts with your US corporation, the foreign corporation would be listed in Part 3. If all transactions are directly with the shareholder in Part 2, Part 3 can reference back to Part 2.
Part 4: Monetary Transactions Between Reporting Corporation and Foreign Related Party
This is the most important section for C-Corporations. Unlike disregarded entities (which use Part 5), corporations report their related-party transactions in Part 4. This section captures the dollar amounts flowing between the corporation and its foreign shareholder or related parties.
Lines 9-22: Amounts Received (Inflows to Corporation)
- Line 9: Purchases of stock in trade
- Line 10: Purchases of tangible property (not stock in trade)
- Line 11: Platform contribution transaction payments received
- Line 13: Loan proceeds received from the foreign related party
- Line 14: Interest received on loans to the foreign related party
- Line 15: Premiums received for insurance or reinsurance
- Line 17: Rents and royalties received
- Line 20: Capital contributions received from the foreign related party
- Line 22: Total (sum of Lines 9 through 21)
Lines 23-36: Amounts Paid (Outflows from Corporation)
- Line 23: Sales of stock in trade
- Line 24: Sales of tangible property (not stock in trade)
- Line 25: Platform contribution transaction payments made
- Line 27: Loan payments made to the foreign related party
- Line 28: Interest paid on loans from the foreign related party
- Line 30: Compensation paid to the foreign related party for services
- Line 31: Rents and royalties paid
- Line 33: Dividends paid to the foreign shareholder
- Line 36: Total (sum of Lines 23 through 35)
Part 5: Reportable Transactions of a Foreign-Owned US Disregarded Entity
Leave Part 5 entirely blank. Part 5 is exclusively for foreign-owned US disregarded entities. Since you are filing as a C-Corporation (a regarded entity), Part 5 does not apply. All monetary transactions are reported in Part 4 instead.
Part 6: Nonmonetary and Less-Than-Full Consideration Transactions
Report nonmonetary transactions such as when the foreign shareholder serves as an officer or director of the corporation without compensation, or when services or property are exchanged at less than fair market value. If the foreign shareholder is both an owner and a director, describe that relationship here. Common entries include “Shareholder serves as director” or “Related party provides management services.”
Part 7: Additional Information
Part 7 asks about the nature of the business relationship between the reporting corporation and the related party. It also asks whether the corporation was a participant in any cost sharing arrangement and whether it claimed any transfer pricing adjustments. For most small to mid-size foreign-owned corporations, the answers will be straightforward.
Part 8: Cost Sharing Arrangements
This section applies only if the US corporation and a foreign related party share the costs and risks of developing intangible property (such as software, patents, or trademarks) under a qualified cost sharing arrangement (CSA). For most small corporations, this section is not applicable.
Part 9: Base Erosion Payments and Base Erosion Tax Benefits (Section 59A)
The base erosion and anti-abuse tax (BEAT) under Section 59A applies only to corporations with average annual gross receipts of $500 million or more over the three preceding tax years. For the vast majority of foreign-owned C-Corporations, this section does not apply and can be left blank.
Dividend Withholding Warning
Critical: 30% Withholding on Dividends to Foreign Shareholders
If the C-Corporation distributes dividends to its foreign shareholders, these distributions are US-source Fixed, Determinable, Annual, or Periodical (FDAP) income subject to a 30% withholding tax rate. The corporation is the withholding agent and is legally responsible for deducting and remitting the tax to the IRS. Failure to withhold creates personal liability for the corporation and potentially for its officers.
When dividends are paid to foreign shareholders, the corporation must:
- 1.Withhold 30% (or the applicable treaty rate) from each dividend payment before distributing the net amount to the foreign shareholder.
- 2.File Form 1042-S for each foreign recipient, reporting the gross income paid and the tax withheld. Due by March 15 of the following year.
- 3.File Form 1042 (Annual Withholding Tax Return for US Source Income of Foreign Persons) as the summary return. Due by March 15.
- 4.Deposit withheld taxes according to the IRS deposit schedule (generally within days of payment for large amounts, or quarterly for smaller amounts).
Treaty Rate Reduction: Many US tax treaties reduce the dividend withholding rate below 30%. For example, certain treaties provide a 15% rate for portfolio dividends and 5% for direct investment dividends (where the shareholder owns 10% or more of the voting stock). To claim a reduced treaty rate, the foreign shareholder must provide the corporation with a valid Form W-8BEN or W-8BEN-E certifying treaty eligibility before the dividend is paid.
Calculating Gross Payments (Lines 1F and 1H)
Part 1 of Form 5472 requires you to report the total value of gross payments made and received. These amounts are derived from the totals in Part 4.
How to Calculate
Line 1F (Gross payments made to related party): Enter the amount from Part 4, Line 36 (total outflows from the corporation to the foreign related party).
Line 1H (Gross payments received from related party): Enter the amount from Part 4, Line 22 (total inflows from the foreign related party to the corporation).
If the corporation files multiple Form 5472s (because it has transactions with multiple foreign related parties each meeting the 25% threshold), the amounts on each individual Form 5472 reflect only the transactions with that specific related party. Do not consolidate amounts across multiple 5472s onto a single form. Each form stands alone with its own Part 4 totals flowing to its own Lines 1F and 1H.
De Minimis Exception Clarification
The $10M Small Corporation Exception Does NOT Exempt You from Filing Form 5472
There is a common misconception that small corporations with less than $10 million in US gross receipts are exempt from Form 5472 requirements. This is incorrect.
The small corporation exception under Section 6038A applies only to certain recordkeeping and agent appointment requirements, not to the Form 5472 filing obligation itself. Specifically:
What the exception exempts (Section 6038A-3 and 6038A-5):
- Certain record maintenance requirements under Reg. 1.6038A-3
- The requirement to authorize a US agent for the foreign related party under Reg. 1.6038A-5
What the exception does NOT exempt:
- Filing Form 5472 (this is always required regardless of size)
- Answering Schedule K Question 7 on Form 1120
- Reporting transactions with foreign related parties
Even if your corporation has zero revenue, you must still file Form 5472 for any tax year in which a reportable transaction occurred with a 25% foreign shareholder. There is no revenue threshold for the filing obligation.
How to Submit
Form 5472 cannot be e-filed. It must be submitted on paper, either by mail or by fax. This is true even if the corporation e-files its Form 1120. When the Form 1120 is e-filed, Form 5472 must be sent separately to the IRS.
Option 1: Mail
Mail Form 5472 to the IRS address specified in the form instructions. The mailing address depends on whether payment is included. Use certified mail with return receipt requested so you have proof of delivery. The IRS does not send an acknowledgment when it receives Form 5472.
Option 2: Fax
Form 5472 can also be faxed to the IRS. The fax number is provided in the form instructions. Keep the fax confirmation page as your proof of submission. Note that fax quality must be clear and legible.
No confirmation from the IRS: Unlike e-filed returns that receive an electronic acceptance, paper-filed Form 5472 submissions do not receive any confirmation from the IRS. You will not know whether the IRS received your form unless you used certified mail or have a fax confirmation. Always retain proof of submission in your records.
Penalties
$25,000 Penalty Per Form, Per Year
The penalty for failure to file Form 5472, or for filing a substantially incomplete Form 5472, is $25,000 per form per tax year. This penalty was increased from $10,000 to $25,000 effective for returns filed after December 31, 2017 (Tax Cuts and Jobs Act). The penalty applies per form, meaning if you are required to file multiple Form 5472s and fail to file all of them, the penalty is $25,000 for each missing form.
Additional penalty consequences include:
Continuation Penalty
If the IRS sends a notice of failure to file and you do not comply within 90 days, an additional $25,000 penalty is assessed for each 30-day period (or fraction thereof) that the failure continues after the 90-day period expires.
Criminal Penalties
Willful failure to file may result in criminal penalties under Section 7203 (failure to file) or Section 7206 (fraud and false statements), in addition to the civil penalties.
Reduction of Foreign Tax Credit
The IRS may reduce or disallow the corporation's foreign tax credit if it fails to comply with the information reporting requirements under Section 6038A.
Withholding Penalties (If Applicable)
If the corporation fails to withhold tax on dividends paid to foreign shareholders, it is liable for the amount that should have been withheld, plus interest and potential penalties under Section 6656 (failure to make deposit of taxes).
Reasonable Cause Defense: The $25,000 penalty may be waived if the corporation can demonstrate reasonable cause for the failure to file. Reasonable cause generally requires showing that the corporation exercised ordinary business care and prudence but was nonetheless unable to comply. Common arguments include reliance on a professional tax advisor, good faith efforts to comply, and lack of willful neglect. If you receive a penalty notice, respond within 30 days with a reasonable cause explanation.
