How to Complete IRS Form 5471 Schedule G: Filing and Penalties

Schedule G of IRS Form 5471 is a multi-page set of roughly two dozen yes-or-no questions about specific activities of the foreign corporation during its tax year, and you complete it as part of Form 5471 attached to your U.S. income tax return. Each question stands alone: a “No” moves you to the next line, while a “Yes” usually triggers a follow-up dollar amount, an attached statement, or a separate form. The schedule is not filed by everyone who files Form 5471, and the questions cover very different areas of international tax law, so the work is less about calculation and more about knowing which of your facts belong on which line.

Who Has to Complete Schedule G

Schedule G is required for filers in Categories 1a, 1b, 1c, 4, 5a, 5b, and 5c.¹ Categories 2 and 3 do not file Schedule G at all.

In broad terms, those categories cover:

Categories 1a, 1b, and 1c: U.S. shareholders of specified foreign corporations, including certain section 965 specified foreign corporations and controlled foreign corporations (CFCs).
Category 4: U.S. persons who control a foreign corporation, meaning more than 50 percent of the total voting power or total value of the stock.
Categories 5a, 5b, and 5c: U.S. shareholders who own 10 percent or more of the total combined voting power or total value of a CFC’s stock.²

One carve-out to note: Category 1b and 5b filers are not required to file Schedule G for foreign-controlled section 965 specified foreign corporations and foreign-controlled CFCs, respectively.¹ Confirm your category before assuming you owe the schedule; the rest of Form 5471 uses the same category system, so the answer is usually already on your return.

What the Questions Cover

Schedule G’s questions are grouped loosely by subject. Reading them in blocks makes it easier to see which ones you can answer “No” and move past quickly, and which need real research.

Entity Ownership and Structure

Question 1 asks whether the foreign corporation held at least a 10 percent interest in any foreign partnership. If yes, you attach a statement listing each partnership’s name, EIN, the forms it filed (such as Form 1065 or 1042), and its tax year dates. Question 2 asks about interests in any trust. Question 3a covers disregarded entities and foreign branches; a “Yes” from a Category 4 or 5 filer also requires Form 8858.¹ Question 3b asks whether the corporation had any qualified business units with a functional currency different from its owner, and a “Yes” requires you to report the number of Forms 8964-TRA attached.

Base Erosion Payments and Denied Deductions

Questions 4a through 5b address payments that could reduce the U.S. tax base. Question 4a asks whether you paid or accrued any base erosion payment to the foreign corporation under Section 59A, or had a base erosion tax benefit tied to such a payment.³ Lines 4b and 4c require dollar amounts when the corporation is a related party and you made or accrued the payment. Question 5a asks whether the corporation paid or accrued interest or royalties disallowed as deductions under Section 267A, with the disallowed total entered on 5b.

FDII, Cost Sharing, and Intangible Property

Question 6a asks whether you are claiming a foreign-derived intangible income deduction under Section 250 with respect to transactions with the foreign corporation. A “Yes” requires dollar amounts on lines 6b, 6c, and 6d, translated from the corporation’s functional currency at the average exchange rate for its tax year. Question 7 asks whether the corporation participated in any cost sharing arrangement; if so, you also file a separate Schedule G-1 for each arrangement.¹ Question 9a covers intangible property the corporation received in a Section 351 or 361 exchange where the U.S. transferor must report annual income inclusions under Section 367(d).

Reorganizations, Reportable Transactions, and Foreign Taxes

Question 8 asks whether the corporation purchased stock or securities of one of its shareholders for a triangular reorganization after April 25, 2014. Question 10 asks whether the corporation was an expatriated foreign subsidiary. Question 11 covers participation in any reportable transaction as defined in the Treasury regulations. Line 12 asks about foreign taxes disqualified for credit under Section 901(m); line 13 covers foreign taxes subject to the suspension rules of Section 909.

Interest Limitation, Extraordinary Reductions, and Section 304 Transactions

Questions 15 and 16 address the Section 163(j) interest expense limitation, covering currently disallowed interest and any carryforward of previously disallowed interest. Question 17a asks about extraordinary reductions with respect to a controlling Section 245A shareholder. Question 21 asks whether any change to the corporation’s earnings and profits (including previously taxed E&P) was tied to a transaction described in Section 304. A “Yes” on 21a requires the change in previously taxed E&P on line 21b(1) and the change in other E&P on line 21b(2), both in functional currency.¹

What to Pull Together Before You Start

Because the questions reach across so many parts of the corporation’s activity, the source documents you’ll need are scattered. Gather these first:

Entity ownership records for anything the foreign corporation holds an interest in: partnership agreements, trust documents, formation records, and the EINs and tax year dates for any foreign partnerships.
Intercompany transaction records: invoices, contracts, and payment records for services, royalties, and interest between you and the foreign corporation. These feed the base erosion payment lines.
Cost sharing arrangement files: the arrangement itself, platform contribution records, and reasonably anticipated benefits calculations, which you’ll need for Schedule G-1.
Foreign tax records, including any amounts disqualified under Section 901(m) or suspended under Section 909.
Intangible property transfer documents for any Section 351 or 361 exchange that moved intangibles to the foreign corporation.
Earnings and profits workpapers, current and accumulated, including previously taxed E&P under Section 959, so you can answer the Section 304 question accurately.
Section 163(j) computations showing any disallowed interest and carryforward amounts.
Exchange rate documentation. If you’re claiming an FDII deduction, all amounts on lines 6b through 6d must be reported in U.S. dollars at the average exchange rate for the foreign corporation’s tax year.¹

Answering the Questions

Work through the lines in order. Every question needs either “Yes” or “No”; there is no “N/A.” Leaving a question blank is a common Form 5471 error and can prompt an IRS notice treating the return as substantially incomplete.

When you answer “Yes,” read the instruction for that specific line before moving on. Some lines only want the checkbox. Others require dollar amounts on follow-up lines, an attached statement with specified data points, or a separate form entirely. Question 3a is a good example: a “Yes” from a Category 4 or 5 filer requires Form 8858, while a filer in another category can attach a simplified statement giving the entity’s name, country of organization, and EIN.¹

If a response needs more space than the form allows, attach a supplemental statement identifying the question number. Cross-check your Schedule G answers against the rest of Form 5471. The E&P figures behind question 21 should be consistent with Schedule J, and the partnership interests behind question 1 should align with any Forms 8865 you file. Inconsistencies between schedules are a common trigger for IRS follow-up.

Where Schedule G Goes and When It’s Due

Schedule G is not filed separately. It travels with Form 5471, which attaches to your U.S. income tax return: Form 1040 for individuals, Form 1120 for corporations, or the applicable partnership or exempt organization return. The filing deadline is the due date of that return, including extensions.¹

If you e-file, Form 5471 and its schedules transmit as part of that filing. For a paper return, attach Form 5471 with all required schedules and any supplemental statements and mail everything to the IRS service center that handles your return type. Keep a full copy of what you send. The IRS may ask about a foreign transaction years later, and reconstructing the file after the fact is much harder than pulling it from an organized folder.

What Happens If You File Late, Incomplete, or Not at All

A $10,000 penalty applies for each annual accounting period of each foreign corporation for which the required information isn’t filed on time.⁴ If the IRS mails you a notice about the failure and you still don’t file within 90 days, another $10,000 penalty applies for each 30-day period the failure continues, up to $50,000 in additional penalty.¹ These amounts run per foreign corporation, so multiple entities multiply the exposure quickly.

Penalties aren’t reserved for the case where you skip the form entirely. The IRS has asserted them where Form 5471 was filed but treated as substantially incomplete, for example when category-of-filer boxes were left blank or Schedule G questions were unanswered. For penalty purposes, an incomplete form can be treated as no form at all. You can request abatement by showing the failure was due to reasonable cause and not willful neglect, and the IRS evaluates that case by case.

The bigger risk is the statute of limitations. Under 26 U.S.C. Section 6501(c)(8), if you fail to file information required under Sections 6038 or 6046 (among others), the normal three-year assessment period on your tax return does not begin until three years after the IRS actually receives the required information. In practical terms, if Form 5471 never gets filed, the IRS can audit and assess additional tax on your entire return indefinitely. A narrow safety valve applies if you can prove the failure was due to reasonable cause and not willful neglect: the open-ended assessment period is then limited to items related to the missing information rather than the whole return.⁵ Filing on time, even with imperfect Schedule G answers you later amend, is much safer than not filing.

The Dormant Corporation Shortcut

If the foreign corporation was essentially inactive throughout its annual accounting period, Revenue Procedure 92-70 lets you file a summary return in place of the full Form 5471, and you skip Schedule G along with the rest of the schedules. The corporation qualifies as dormant only if all of the following were true for the entire year:¹

The corporation conducted no business and owned no stock in any other corporation, except another dormant foreign corporation.
No shares were sold, exchanged, redeemed, or transferred, other than directors’ qualifying shares, and the entity was not party to a reorganization.
No assets were sold, exchanged, or transferred, except minimal amounts related to the small income and expenses described below.
Gross income was no more than $5,000 and expenses were no more than $5,000.
Total assets, under U.S. GAAP and before reducing for liabilities, were less than $100,000.
No distributions were made.
The corporation had no current or accumulated E&P, or only minimal changes tied to the small income and expenses above.

If every condition is met, you file only page 1 of Form 5471 for that corporation, labeled “Filed Pursuant to Rev. Proc. 92-70 for Dormant Foreign Corporation” in the top margin, with filer information, the corporation’s annual accounting period, and its identification details. That satisfies both Section 6038 and Section 6046 reporting.¹ A corporation that was dormant last year but fails a condition this year cannot use the summary procedure and must file the complete form.

Schedule G Is Not Schedule G-1

These are different schedules and are easy to confuse. Schedule G is the set of yes-or-no questions covered above. Schedule G-1 is filed only when the foreign corporation participated in a cost sharing arrangement during the tax year, and you file one Schedule G-1 for each arrangement, reporting the corporation’s share of reasonably anticipated benefits, platform contributions, and the pricing methods used.¹ Answering “Yes” to Schedule G question 7 is what pulls Schedule G-1 into your return. Schedule G flags the arrangement; Schedule G-1 supplies the financial detail.
