IRS Form 5471: Who Needs to File, Due Date, and Instructions

What Form 5471 Is and How It Works

Form 5471, Information Return of U.S. Persons With Respect To Certain Foreign Corporations, is the disclosure form the Internal Revenue Service uses to track US ownership, control, and financial activity in foreign corporations under Internal Revenue Code sections 6038 and 6046.

You must complete a separate Form 5471 and all applicable schedules for each foreign corporation you are required to report. Even when a required schedule has no activity for the year, the IRS instructions state that you must still file the schedule with one or more zero amounts.

• US persons include US citizens, US residents, domestic partnerships, domestic corporations, and domestic estates or trusts.
• If you qualify under more than one filing category for the same foreign corporation, you file one Form 5471 for that corporation and complete every schedule that applies across your categories without duplicating data.
• If you satisfy the rules for both Category 4 and Category 5a, the IRS instructs you to check only the box for Category 4 in Item B on page 1 and leave the Category 5a box blank.
• When multiple people are required to file Form 5471 for the same foreign corporation for the same period, one person with the same or greater filing requirements may file a joint Form 5471 and the applicable schedules on behalf of the others.

Who Must File Form 5471: The 5 Filer Categories

The IRS divides Form 5471 filers into 5 categories based on your role, your ownership percentage, and whether the foreign corporation is a Controlled Foreign Corporation (CFC) or a section 965 Specified Foreign Corporation (SFC). Categories 1 and 5 are split into subcategories a, b, and c under Revenue Procedure 2019-40 for certain foreign-controlled corporations.

A foreign corporation is generally a CFC if US shareholders (each owning 10% or more of the vote or value directly, indirectly, or constructively under section 958) collectively own more than 50% of the total combined voting power or total value of the corporation's stock on any day of its tax year. A section 965 SFC is any CFC, or any foreign corporation with at least one domestic corporation as a 10% US shareholder (excluding a passive foreign investment company that is not a CFC).

• Category 1 (1a, 1b, 1c): A US shareholder (owning 10% or more of vote or value) of a section 965 SFC at any time during the foreign corporation's tax year who owned that stock on the last day of that year on which it was a section 965 SFC. Reporting continues as long as the corporation has accumulated earnings and profits (E&P) related to section 965 on Schedule J or the shareholder has previously taxed E&P (PTEP) related to section 965 on Schedule P. Category 1b applies to an unrelated section 958(a) US shareholder of a foreign-controlled section 965 SFC. Category 1c applies to a related constructive US shareholder of a foreign-controlled section 965 SFC. Category 1a covers all other Category 1 filers.
• Category 2: A US citizen or resident who is an officer or director of a foreign corporation in which a US person has acquired, in one or more transactions, stock that meets the 10% stock ownership requirement (10% or more of total value or total combined voting power) or an additional 10% or more in value or voting power.
• Category 3: A US person who acquires stock in a foreign corporation that meets the 10% ownership threshold (alone or added to existing stock), a person treated as a US shareholder under section 953(c), a person who becomes a US person while meeting the 10% stock ownership requirement, or a US person who disposes of enough stock to reduce their interest to less than 10%.
• Category 4: A US person who had control of a foreign corporation at any time during that person's tax year during the foreign corporation's annual accounting period. Control means owning more than 50% of the total combined voting power or more than 50% of the total value of shares. For Category 4 only, a US person also includes a nonresident alien with an active election under section 6013(g) or 6013(h) to be treated as a US resident.
• Category 5 (5a, 5b, 5c): A US shareholder (owning 10% or more of vote or value) who owned stock in a foreign corporation that was a CFC at any time during the foreign corporation's tax year and who owned that stock on the last day in that year on which it was a CFC. Category 5b covers an unrelated section 958(a) US shareholder of a foreign-controlled CFC. Category 5c covers a related constructive US shareholder of a foreign-controlled CFC. Category 5a covers all other Category 5 filers.

Form 5471 Schedules Required for Each Category

Your filer category dictates which pages and separate schedules you must attach. Under the IRS Instructions for Form 5471 Filing Requirements chart, a Category 4 filer (such as a sole owner of a foreign corporation) is responsible for all 6 pages of the base form plus up to 10 separate schedules.

Form 5471 Due Date and Accounting Period Rules

Form 5471 does not have a standalone filing deadline. You attach Form 5471 to your federal income tax return (or your partnership or exempt organization return) and file both together by the due date for that return, including any valid extensions.

• Standard accounting period rule: Except for Schedule O, you report financial and tax information for the foreign corporation's tax year that ends with or within your US tax year.
• Schedule O exception: When filing Schedule O, you report stock acquisitions, dispositions, organizations, or reorganizations that occurred during your own US tax year.
• Repeal of the 1-month deferral rule: Under section 70352 of Public Law 119-21 (enacted July 4, 2025, known as the One Big Beautiful Bill Act or OBBBA), for any tax year of a section 898 specified foreign corporation (SFC) beginning after November 30, 2025, the SFC may not have a tax year beginning one month earlier than the majority US shareholder's tax year. Its required year must generally match the majority US shareholder's tax year.

What Financial Records You Need (And Our Preparation Checklist)

For Category 3 and Category 4 filers, Schedule C (Income Statement) must be prepared in the foreign corporation's functional currency in accordance with US Generally Accepted Accounting Principles (US GAAP) and translated into US dollars using US GAAP translation principles. Schedule F (Balance Sheet) must be reported in US dollars.

If you are an unrelated US shareholder of a foreign-controlled CFC or SFC and standard tax records under section 964 are not readily available, Revenue Procedure 2019-40 provides a safe harbor. You may check Item F on page 1 and enter an Alternative Information Code in Item G (codes 01 through 08), using audited or unaudited US GAAP, IFRS, or local-country GAAP statements, or separate-entity tax or internal management records, in strict priority order. Below is the preparation checklist our team built to gather what Form 5471 requires.

• Corporate profile and IDs: Confirm the foreign corporation's legal name, any prior names used within the past 3 years, and its foreign address. Record its functional currency using the 3-letter ISO 4217 code for Item 1h and its 6-digit Principal Business Activity code for Items 1f and 1g. Provide either its US EIN or a unique alphanumeric Reference ID number in Item 1b(2).
• Stock and shareholder register (Schedules A and B): Gather share class details along with beginning and ending share counts. For Schedule B, Part I, list each 10% US shareholder's name, address, identifying number, and allocable percentage of Subpart F income. For Schedule B, Part II, list all direct owners.
• US GAAP financial statements (Schedules C and F): Compile the functional currency income statement adjusted to US GAAP. Break out unrealized and realized foreign currency transaction gains and losses on lines 8a and 8b, and report current and deferred income tax expense under ASC 740 on lines 21a and 21b. Prepare the US dollar balance sheet, reporting gross short-term and long-term derivative assets on line 3 and liabilities on line 17 under ASC 815 without netting.
• Foreign tax payment records (Schedules E and E-1): Collect local tax returns and payment receipts showing income, war profits, and excess profits taxes paid or accrued in local currency. Record the foreign taxable income base and note whether any prior-year foreign tax redeterminations occurred under section 905(c).
• Earnings and profits adjustments (Schedules H, J, P, and R): Prepare book-to-tax adjustments under Regulations section 1.964-1 to compute current E&P on Schedule H. These adjustments cover depreciation under section 167, inventory under sections 471 and 263A, and tax expense reconciliations. Track accumulated E&P and the 10 PTEP subgroups on Schedules J and P, and list all cash or property distributions by date and Code section on Schedule R.
• Related-party ledgers and stock event records (Schedules M and O): Summarize all gross receipts, payments, and the largest outstanding loan and accounts receivable or payable balances during the year with related parties for Schedule M. Record exact dates, share counts, and methods for any stock acquisitions or dispositions on Schedule O. Category 3 filers must also attach a mandatory statement detailing the amount and type of indebtedness the foreign corporation has with certain related persons, as well as the name, address, identifying number, and shares subscribed to by each stock subscriber.

Formatting Rules, Common Pitfalls, and Worked Example

Every exchange rate reported anywhere on Form 5471 or its schedules must use the divide-by convention rounded to at least 4 decimal places. You report the units of foreign currency that equal 1 US dollar, never the number of US dollars that equal 1 unit of foreign currency.

Worked Example (Foreign Tax Currency Translation on Schedule E): Suppose your foreign corporation in Japan paid 30,255,400 Japanese Yen (JPY) in foreign income taxes during its annual accounting period. Under section 986(a), you translate these taxes using the average exchange rate for the tax year. If the average rate is 108.8593 JPY to 1 US dollar (0.009184 US dollars to 1 JPY), you enter 108.8593 in column (k) of Schedule E, Part I, Section 1, and divide 30,255,400 by 108.8593 to enter $277,931 in column (l).

• Never enter FOREIGNUS or APPLIED FOR: If the foreign corporation does not have a US EIN, you must create and assign a unique alphanumeric Reference ID number up to 50 characters long with no spaces or special characters, and use that Reference ID consistently every tax year (and on any related Form 8858 or Form 8992).
• Never write See attached in blank sections: If your data exceeds the lines provided in a section of Form 5471, fill in every entry space on the IRS form first and attach conforming sheets only for the remaining overflow items.
• Do not net loan balances on Schedule M: On Schedule M, lines 32 and 34, report the largest outstanding gross balances during the year of amounts borrowed from and loaned to related parties, not year-end, average, or net balances.
• Check Item E to avoid duplicate Form 8938 reporting: If you report excepted specified foreign financial assets on Form 5471, check the Item E box on page 1. You then do not have to report those same assets on Form 8938, other than completing Form 8938, Part IV, line 17.
• How to correct a previously filed Form 5471: File a Form 5471 with the word Corrected written at the top, attach a statement identifying the changes, and submit it with an amended tax return for the original return.

Penalties for Failing to File Form 5471

Missing Form 5471 or filing an incomplete return triggers dollar penalties and foreign tax credit reductions under Internal Revenue Code sections 6038 and 6046. If you agree to let another person file Form 5471 and Schedule J, M, or O on your behalf under the joint filers rule, you remain subject to these penalties if that person fails to file a correct form.

• Section 6038(a) monetary penalty (Form 5471 and Schedule M): $10,000 for each annual accounting period of each foreign corporation. If not filed within 90 days after the IRS mails a notice of failure, an additional $10,000 penalty applies for each 30-day period (or fraction thereof) after the 90-day window expires, up to $50,000 additional per failure.
• Section 6038 foreign tax credit reduction: A 10% reduction in the foreign taxes available for credit under sections 901 and 960, plus an additional 5% reduction for each 3-month period (or fraction thereof) if the failure continues 90 days or more after the IRS mails a notice.
• Section 6046 monetary penalty (Form 5471 and Schedule O): $10,000 for each failure per reportable transaction, plus $10,000 for each 30-day period (or fraction thereof) if the failure continues more than 90 days after an IRS notice, up to $50,000 additional.
• Accuracy and criminal penalties: Undisclosed foreign financial asset understatements are subject to penalties under section 6662(j) unless the taxpayer shows reasonable cause and good faith. Criminal penalties under sections 7203, 7206, and 7207 may also apply.

Practice Scenario: Identifying Your Form 5471 Category and Schedules

Case Diagnostic: Suppose you are a US citizen who purchased 100% of the stock of an existing foreign corporation on May 1 of your current tax year and served as its sole director through December 31. Which Form 5471 filer categories apply to you for this year, which category boxes do you check in Item B on page 1, and which schedules must you attach?

Because you are a US citizen who acquired 100% of the foreign corporation's stock on May 1 and served as its director, you meet the definitions for 4 categories in your first year. You are a Category 2 filer because you are a US citizen serving as a director in a year a US person acquired 10% or more of the stock. You are a Category 3 filer because you acquired stock meeting the 10% ownership threshold. You are a Category 4 filer because you owned more than 50% of the vote and value during the corporation's annual accounting period. You are also a Category 5a filer because you owned 10% or more of a Controlled Foreign Corporation on the last day of its tax year. Under the IRS Item B instructions, when you satisfy both Category 4 and Category 5a, you check only the Category 4 box and leave Category 5a blank. Therefore, in Item B, you check Categories 2, 3, and 4. Without duplicating schedules, you must complete all 6 pages of Form 5471 (including Schedules A, B Parts I and II, C, F, G, and I), attach separate Schedules E, E-1, G-1, H, I-1, J, M, O (Parts I and II), P, Q, and R, and include the mandatory Category 3 statement on related-party debt and stock subscribers.
