Form 5471 (Rev. December 2021) Tax Year 2021 Checklist
The December 2021 revision of Form 5471 introduces significant reporting changes for U.S. persons with interests in controlled foreign corporations. These updates include section 245A extraordinary disposition and reduction account tracking, enhanced subpart F income calculations for tiered structures, and foreign-derived intangible income deduction substantiation for domestic C corporations. Understanding these filing requirements ensures compliance with sections 6038 and 6046 of the Internal Revenue Code while avoiding substantial penalties for incomplete or inaccurate tax form submissions.
Determining CFC Status and U.S. Shareholder Obligations
A foreign corporation qualifies as a controlled foreign corporation when U.S. shareholders own more than 50% of either total combined voting power or total stock value on any day during the corporation’s tax year. U.S. shareholders include citizens, residents, domestic partnerships, domestic corporations, and certain trusts that own 10% or more of voting power or value.
Category 4 filers must report when they control a foreign corporation by owning more than 50% of voting power or value during the annual accounting period. Category 5a, 5b, and 5c filers face different requirements based on their relationship to foreign-controlled corporations and whether they own stock directly under section 958(a) or constructively.
Completing Page 1 Identification and Item H Requirements
Filers who complete Form 5471 on behalf of other U.S. shareholders must provide comprehensive identification in Item H on page 1. This section requires the shareholder’s name, complete address, and identifying number for each Category 4, 5a, or 5b person. Box H(4) must determine whether the relationship involves shareholder, officer, or director status. A separate Schedule I accompanies each person listed in Item H.
The filer must check appropriate boxes in Item B to indicate all applicable categories on this tax form, as multiple categories often apply simultaneously when ownership structures involve both control and CFC shareholder status. Schedule A reports the foreign corporation’s stock classes and outstanding shares at the beginning and end of the accounting period.
Schedule B and Schedule C Reporting Requirements
Schedule B identifies U.S. shareholders who owned 10% or more of the foreign corporation’s voting power or value at any time during the annual accounting period. Part I reports U.S. shareholders, while Part II reports direct shareholders regardless of nationality.
Schedule C requires complete dual-column reporting with functional currency amounts in accordance with U.S. generally accepted accounting principles alongside U.S. dollar translations. Each line item must appear in both columns unless the foreign corporation already uses U.S. dollars as its functional currency. Corporations applying the dollar approximate separate transactions method follow special translation rules detailed in the 2021 instructions.
Schedule F Balance Sheet with Derivative Instruments
The balance sheet reports assets and liabilities as of the beginning and end of the 2021 accounting period in U.S. dollars translated in accordance with U.S. GAAP. Line 3 captures derivative instruments on the assets side, while line 17 reports derivatives on the liabilities side.
These line items represent additions to the 2021 tax form specifically designed to capture derivative financial instruments under ASC 815 standards. Positions must not be netted, and reporting must include both short-term and long-term derivatives. The paid-in capital surplus on line 21 requires reconciliation when changes occur during the accounting period.
Section 245A Extraordinary Disposition and Reduction Accounts
Schedule I lines 5b and 5c capture extraordinary disposition amounts and extraordinary reduction amounts, as applicable, for transactions that occurred during 2021. Schedule G question 22a asks whether any extraordinary reduction with respect to a controlling section 245A shareholder occurred during the tax year.
Question 22b follows when the answer is yes, asking whether an election closed the tax year to prevent amounts from being classified as extraordinary reduction amounts. Attachments must detail opening balances, changes, and closing balances for both the shareholder’s extraordinary disposition account on line 8b and the CFC’s aggregate extraordinary disposition account on line 8c. Line 8a requires a yes or no confirmation regarding whether the U.S. shareholder maintained an extraordinary disposition account at any time during the tax year.
Subpart F Income and GILTI Calculations
Schedule I lines 1e through 1h capture section 954 subpart F income components calculated through Worksheet A. These categories include foreign personal holding company income under section 954(c), foreign base company sales income under section 954(d), foreign base company services income under section 954(e), and other subpart F income not classified in preceding categories.
Lines 1c and 1d report tiered extraordinary disposition amounts and tiered extraordinary reduction amounts only when these amounts fail to qualify for the section 954(c)(6) exception.
Schedule I-1 reports information for global intangible low-taxed income calculations at the CFC level. Category 4 and 5a filers must complete Schedule I-1 to provide tested income, tested loss, and qualified business asset investment amounts. Schedule I-1 data flows to U.S. shareholders’ GILTI inclusion computations on their respective tax form filings.
Section 250 FDII Deduction Substantiation for C Corporations
Domestic C corporations claiming foreign-derived intangible income deductions under section 250 must answer yes to Schedule G question 6a when the deduction relates to transactions with the reported foreign corporation. Lines 6b, 6c, and 6d require separate reporting of gross income amounts.
Line 6b captures income from sales, exchanges, or dispositions, excluding licenses. Line 6c reports gross income from property licenses. Line 6d details gross income from services provided to the foreign corporation. These amounts support the section 250 deduction calculation on Form 8993 and the domestic corporation’s Form 1120 for tax year 2021.
Transfer Pricing and Debt-Equity Compliance Reporting
Question 18 addresses loans using safe-haven applicable federal rate rules under Regulations section 1.482-2 of the Regulations during the 2021 tax year. The safe-haven range spans 100% to 130% of the applicable federal rate for the relevant term. Question 19a identifies section 385 distributions or acquisitions paired with related-party indebtedness during the 2021 tax year or surrounding 36-month periods. Affirmative answers require dollar amount entries on lines 18 or 19b.
Schedule M reports transactions between the controlled foreign corporation and shareholders or other related persons during the annual accounting period. Category 4 and 5a filers must complete Schedule M to disclose related-party transactions that may trigger transfer pricing scrutiny.
Base Erosion and Anti-Abuse Tax Amounts
Question 4a requires yes responses when the filer paid or accrued base erosion payments under section 59A(d) to the foreign corporation or claimed base erosion tax benefits under section 59A(c)(2). Lines 4b and 4c capture total dollar amounts for these transactions.
This disclosure supports base erosion and anti-abuse tax calculations for domestic C corporations with foreign related-party transactions. Section 267A requires confirmation of question 5a when a foreign corporation paid or accrued interest or royalties with disallowed deductions under hybrid mismatch rules, with line 5b capturing the total disallowed amounts.
Interest Expense Limitations and Carryforwards
Questions 15 and 16 address interest expense disallowed under section 163(j) limitations applicable to foreign corporations. Question 15 captures current tax year disallowances, while question 16 reports previously disallowed amounts carried forward from prior years. Dollar amounts must appear when either question receives affirmative responses. The 2021 tax form clarifies that Section 163(j) net interest expense restrictions apply to the deduction limits of foreign corporations under the Tax Cuts and Jobs Act provisions.
Required Supplemental Schedules and Attachments
Form 8858 attachments accompany affirmative responses to question 3 regarding disregarded foreign entities or foreign branches. Question 1 affirmative responses regarding foreign partnership interests require detailed statements.
Category 3 filers must attach statements showing indebtedness amounts with related persons and complete subscriber information, including names, addresses, identifying numbers, and subscribed shares. Schedule I-1 coordinates with Schedule J for earnings and profits calculations across income categories. Schedule O captures organization or reorganization information for Category 2 and 3 filers reporting acquisition or disposition transactions. Multiple schedules require separate completion by income category, particularly Schedules E, I-1, J, P, and Q, which report amounts across general category, passive category, and section 901(j) category classifications.
