Form 5471 Schedule M: reporting CFC related-party transactions in 2026
Schedule M of Form 5471 reports specified transactions between a controlled foreign corporation and certain US persons or related entities. For a calendar-year CFC’s 2025 tax year filed in 2026, the current Schedule M remains the December 2021 revision, while the governing Form 5471 instructions are dated December 2025.
As of October, 2026, the IRS has also published proposed regulations addressing sections 951, 951A, and 6038, covered below. Those developments matter for post-2025 reporting, but they do not replace the Schedule M rules applicable to a 2025 CFC tax year.
What is Form 5471 Schedule M? A plain-English overview
Form 5471 Schedule M is the schedule a Category 4 filer uses to report specified transactions between a controlled foreign corporation and the 5 counterparty groups in columns (b) through (f). For 2025 tax-year filings, Schedule M forms part of the information required under IRC section 6038.
Schedule M captures specified amounts moving between a CFC and the US persons or entities identified on the form, giving the IRS transaction information required under section 6038. It does not itself calculate the shareholder’s income tax.
The following 5 transaction groups account for much of what appears on the schedule:
- Sales and purchases of inventory, tangible property, and property rights.
- Services, commissions, rents, royalties, platform contributions, and cost-sharing payments.
- Dividends, interest, insurance amounts, and loan-guarantee fees.
- Accounts receivable, accounts payable, amounts borrowed, and amounts loaned.
- Other reportable amounts that require supporting statements on lines 14 or 29.
The schedule sits within the wider foreign subsidiary reporting package described in our Form 5471 filing guide for US owners of foreign corporations. The IRS Form 5471 page identifies the current form, instructions, separate schedules, and recent developments.
For 2025, this US shareholder reporting remains governed by the December 2025 Form 5471 instructions even though the IRS has begun publishing materials for later years.
Who must file Schedule M: category of filer rules
Only Category 4 filers must complete Schedule M under the December 2025 Form 5471 instructions. A Category 4 filer is a US person who controlled the foreign corporation, generally through ownership of more than 50% of its voting power or total stock value at some point during the relevant year.
Only Category 4 filers are specifically required to complete Schedule M for transactions during the foreign corporation’s annual accounting period. Category 5 status by itself does not create the Schedule M requirement.
The following 3 distinctions determine whether the schedule is required:
- Category 4 filer: Schedule M is required unless a filing exception applies.
- Category 5 filer only: Category 5 status alone does not require Schedule M.
- Category 1, 2, or 3 filer only: Those categories do not independently trigger Schedule M.
Control can arise through direct, indirect, or constructive ownership. Our guide to IRS constructive ownership rules for foreign entities explains why stock held through another corporation or attributed under the applicable rules can change a filer’s category.
The controlling source is the current IRS Instructions for Form 5471, which state that every US person described in Category 4 must file Schedule M.
Controlled foreign corporation defined: the foundation of Schedule M
For 2025 filing purposes, a controlled foreign corporation is generally a foreign corporation whose US shareholders own, directly, indirectly, or constructively, more than 50% of its voting power or total stock value. A US shareholder generally meets a separate threshold of at least 10% of voting power or value.
A corporation is generally a CFC when US shareholders, each meeting the applicable 10% US shareholder test, collectively own more than 50% of the foreign corporation by vote or value.
That CFC test is related to, but not identical to, the Category 4 control test. A shareholder may need to examine foreign corporation ownership through direct holdings, indirect chains, and constructive ownership before deciding which Form 5471 schedules apply.
For a fuller explanation of the 10% and more-than-50% tests, review our guide to controlled foreign corporations and US tax reporting.
The IRS proposed changes on August 26, 2026, affecting sections 951 and 951A for later foreign-corporation tax years. Those proposed rules do not retroactively change the 2025 CFC and Schedule M reporting discussed here.
Transactions reported on Schedule M: line-by-line breakdown
Schedule M contains 34 numbered lines covering amounts received, amounts paid, and selected year-high balances between the foreign corporation and 5 counterparty groups. The current form separately identifies sales, purchases, services, rents, royalties, dividends, interest, loans, receivables, payables, and several less common transaction types.
The key reporting rule is to match each amount to both the correct Schedule M line and the correct one of 5 counterparty columns.
| Line reference | Transaction type | Reporting treatment |
|---|---|---|
| 1–8 and 16–23 | Sales, purchases, platform contributions, cost sharing, services, commissions, rents, royalties | Report amounts received or paid during the CFC year |
| 9–13 and 24–28 | Hybrid dividends, dividends, interest, insurance, loan-guarantee fees | Report in the applicable received or paid line |
| 14–15 and 29–30 | Other amounts and totals | Lines 14 and 29 require supporting statements when amounts are entered |
| 31 and 33 | Accounts payable and accounts receivable | Report the largest aggregate outstanding qualifying balance during the year |
| 32 and 34 | Amounts borrowed and amounts loaned | Report the largest outstanding gross balance during the year, not year-end, average, net, or aggregate cash flow |
Lines 31 and 33 have special rules for trade or service receivables and payables. The Form 5471 Schedule M instructions also state that line 32 and line 34 require the largest gross balance outstanding during the year, which makes a year-end balance an incorrect substitute when the peak amount occurred earlier.
For the surrounding entity-reporting rules, review TFX’s guide to foreign company tax reporting for US persons. The underlying line layout is available in the official IRS Schedule M PDF.
How to complete the column structure: US person vs. related party columns
Schedule M uses 5 counterparty columns, not 3: columns (b) through (f) separate the filer, controlled domestic entities, controlled foreign entities, other 10%-or-more US shareholders, and certain 10%-or-more US shareholders of a corporation controlling the CFC. All 2025 amounts are translated to US dollars.
Misallocating a transaction to the wrong Schedule M column can misstate which related person was involved even when the dollar amount itself is correct.
The following 5 columns must be distinguished before entering an amount:
- Column (b): the US person filing Form 5471.
- Column (c): a domestic corporation or partnership controlled by the filer.
- Column (d): another foreign corporation or partnership controlled by the filer.
- Column (e): a 10%-or-more US shareholder of the CFC other than the filer.
- Column (f): a 10%-or-more US shareholder of a corporation controlling the CFC.
For Form 5471 Sch. M, amounts translated from functional currency use the average exchange rate for the foreign corporation’s tax year, and the rate is reported using the IRS divide-by convention.
Our guide to reporting the timing of foreign income and foreign taxes provides additional context when foreign-currency records feed several US forms.
Related party defined: who counts as a related person for Schedule M?
Schedule M identifies reportable counterparties through the 5 groups printed in columns (b) through (f) and the section 6038 reporting rules. These groups include the filer, entities controlled by the filer, other 10% or more US shareholders of the CFC, and certain shareholders of a corporation that controls the CFC.
For Schedule M, use the counterparty definitions built into section 6038 and the form rather than importing a broader related-party definition from an unrelated international reporting regime.
The following 5 categories correspond to the Schedule M column structure:
- The US person filing the return.
- A domestic corporation or partnership controlled by that filer.
- A foreign corporation or partnership controlled by that filer.
- A US shareholder, other than the filer, owning 10% or more of the CFC.
- A qualifying 10%-or-more US shareholder of a corporation controlling the CFC.
Indirect and constructive ownership can affect whether a person falls within a required ownership category. That is why the legal ownership chart should be reviewed before the CFC transactions are mapped to columns.
For background on how US international reporting changed for specified foreign corporations, review TFX’s discussion of specified foreign corporations and US shareholders after tax reform.
Transfer pricing implications of Schedule M transactions
Schedule M does not independently require a transfer-pricing study, but several lines report transactions governed by section 482 principles. For 2025, the IRS instructions specifically reference cost-sharing payments, platform contribution transactions, and loan-guarantee fees, while other intercompany services, financing, and property transactions can also require arm’s-length pricing.
A Schedule M entry is not automatically an audit trigger, but the reported amount should agree with the CFC’s books and with the pricing treatment applied under section 482 where that section governs.
Lines 4 and 19 refer to platform contribution transaction payments under Treasury Regulation section 1.482-7. Lines 5 and 20 cover cost-sharing transaction payments, while lines 13 and 28 expressly direct filers to section 482 for loan-guarantee fees.
Records supporting the transaction should identify the parties, agreement, amount, currency, accounting treatment, and pricing method where relevant. The same transaction may also matter when determining Subpart F income, deductions, tested income, or other CFC attributes.
For transactions involving related-party sales or services, TFX’s Subpart F income guide explains the separate income-inclusion rules that can apply.
Schedule M and Subpart F income: the connection you cannot ignore
A transaction reported on Schedule M can also affect Subpart F income, but the Schedule M entry does not by itself make an amount taxable under IRC section 951. For 2025, related-party sales and services must be tested separately under the applicable section 954 rules before determining the US shareholder’s inclusion.
Schedule M identifies the transaction; the Subpart F rules determine whether that transaction produces an income inclusion for a US shareholder.
The relationship can be tested through the following 3-step sequence:
- Identify the sale, service, interest payment, royalty, or other CFC transaction reported on Schedule M.
- Apply the relevant section 954 rule to determine whether the transaction produces foreign base company income or another Subpart F category.
- If Subpart F applies, determine the US shareholder’s inclusion under IRC section 951 and report it through the applicable Form 5471 schedules and income-tax return.
A related-party sale is not automatically Subpart F income. The place of manufacture, location of services, relationship of the parties, exceptions, and other statutory facts can change the result.
TFX’s comparison of Subpart F income vs. GILTI for CFC owners helps separate these 2 CFC income regimes.
GILTI and Schedule M: how CFC transactions affect your GILTI calculation
Schedule M does not calculate GILTI, but the underlying transactions can affect a CFC’s income, deductions, and tested-income figures elsewhere in Form 5471. For a 2025 CFC tax year, the existing section 951A rules still govern the shareholder's GILTI calculation even though the IRS proposed post-2025 changes on August 26, 2026.
An incorrect Schedule M amount can be a sign that the CFC books feeding the tested-income calculation are also incorrect, but Schedule M itself is not the GILTI computation schedule.
For 2025 reporting, Schedule Q and the other CFC income schedules classify the amounts used in the section 951A and foreign tax credit calculations. A reconciliation between Schedule M, the CFC income statement, and the tested-income schedules can expose differences before filing.
The August 2026 proposed regulations address the post-2025 section 951A regime and related section 6038 reporting. Because they are proposed and principally prospective, a filer should not rewrite a 2025 GILTI calculation as though those rules were already final for 2025.
TFX’s GILTI guide for US owners of foreign companies covers the underlying section 951A rules.
Get help filing Form 5471 Schedule M
A Category 4 filer must coordinate Schedule M with the rest of Form 5471, and the schedule itself contains 34 transaction lines plus 5 counterparty columns. If your 2025 CFC records include intercompany loans, services, royalties, distributions, or cost-sharing payments, those records need to be mapped consistently across the filing.
Form 5471 Schedule M penalties: what happens if you miss it?
Failure to provide information required under section 6038, including required Form 5471 Schedule M information, can trigger a $10,000 penalty for each annual accounting period of each foreign corporation. After IRS notice, continuation penalties can add $10,000 for each 30-day period or fraction, up to $50,000 more per failure.
The statutory section 6038 exposure starts at $10,000 per foreign corporation per annual accounting period and can rise by another $50,000 if the failure continues after the 90-day notice period.
Section 6038 can also reduce foreign taxes otherwise available for credit under sections 901 and 960. The initial reduction is 10%, followed by an additional 5% for each 3-month period or fraction after the post-notice 90-day period, subject to statutory limits.
A Schedule M error does not mean the maximum penalty automatically applies. The relevant question is whether the filer failed to furnish the information required by section 6038 within the prescribed time and whether a statutory or reasonable-cause defense applies.
For a fuller explanation of the penalty rules, see TFX’s guide to Form 5471 penalties and late-filing consequences.
Reasonable cause exception and penalty abatement for Schedule M
Reasonable cause can support relief from a section 6038 penalty, but there is no automatic Schedule M waiver merely because the taxpayer previously had a clean filing history. In 2026, the IRS began transitioning from First Time Abate to AEP, and information reporting dependent on another filing is expressly excluded from AEP.
First-time abatement or AEP should not be presented as the default remedy for a missing Schedule M; reasonable cause depends on the specific facts and supporting evidence.
The following 3 points matter when evaluating relief:
- Reasonable cause: explain the facts showing why the failure occurred despite ordinary business care and prudence, with supporting records where available.
- Substantial compliance: determine whether the filing actually furnished the information required by the statute and regulations.
- Prompt correction: filing a corrected Form 5471 and responding to an IRS notice can support the factual record, but correction alone does not guarantee abatement.
The IRS states that taxpayers who do not qualify for administrative relief can still request reasonable-cause relief, which the agency evaluates on the facts presented.
Schedule M vs. other Form 5471 schedules: how they fit together
Schedule M is only 1 part of Form 5471. For 2025 filings, Schedules E, J, M, P, and Q report different pieces of the foreign corporation’s tax information, and their filer-category requirements are not identical. Schedule M stands out because the current instructions assign it specifically to Category 4 filers.
Schedule M reports specified intercompany transaction flows, while Schedules E, J, P, and Q principally report foreign taxes, earnings and profits, PTEP, or income-category information.
| Schedule | Primary purpose | Who files it under the current instructions |
|---|---|---|
| Schedule E | Foreign taxes paid, accrued, or deemed paid | Applicable Category 1, 4, and 5 filers according to the specific subcategory rules |
| Schedule J | Accumulated earnings and profits | Category 1a, 4, and 5a filers |
| Schedule M | Related-party transactions | Category 4 filers |
| Schedule P | Previously taxed earnings and profits | Category 1a, 1b, 4, 5a, and 5b filers |
| Schedule Q | CFC income by category | Applicable Category 4 and Category 5 filers under its instructions |
The schedules should be reconciled rather than treated as interchangeable. A dividend, service payment, or intercompany financing item can appear in the accounting records that feed several schedules while each schedule reports a different tax attribute.
For the earnings-and-profits side of the filing, review TFX’s Form 5471 Schedule J guide.
Schedule E and Schedule Q: how they interact with Schedule M data
Schedule E and Schedule Q report information different from Schedule M, but all 3 may depend on the same underlying CFC books. Schedule E deals with foreign taxes, while Schedule Q classifies CFC income by category; Schedule M separately identifies transactions with the 5 specified counterparty groups.
Getting the underlying transaction records right supports consistency across Schedule M, Schedule E, and Schedule Q, even though no single Schedule M entry mechanically determines the other 2 schedules.
A royalty or service payment, for instance, can affect CFC income while foreign tax on related income is reported under the Schedule E rules. The resulting income classification may also affect Schedule Q and, depending on the shareholder, sections 904 or 960.
The IRS posted a September 14, 2026 development on its Form 5471 page about new foreign tax allocation reporting in the Schedule E instructions. That development does not change the transaction-line structure of the December 2021 Schedule M.
For the foreign-tax component, use TFX’s Form 5471 Schedule E guide.
Common Schedule M mistakes and how to avoid them
Schedule M errors commonly come from the mechanics of the form rather than a single dollar threshold. For 2025, the IRS requires Category 4 filers to use 5 counterparty columns, the CFC’s average exchange rate, special peak-balance rules on lines 31–34, and supporting statements for specified “other” amounts.
The safest filing approach is to reconcile Schedule M to the CFC ledger and apply the line-specific IRS instructions instead of relying on year-end balances or a perceived materiality threshold.
The following 6 errors deserve a specific pre-filing check:
- Omitting indirect or attributed counterparties. Ownership rules can place a transaction in a reportable counterparty group even where the filer did not hold the interest personally.
- Using a year-end exchange rate. Schedule M uses the CFC’s average exchange rate for its tax year.
- Reporting loan cash flows or year-end balances on lines 32 or 34. Those lines require the largest outstanding gross balance during the year.
- Leaving out services because the amount seems immaterial. The Schedule M instructions do not provide a general small-dollar exemption for the ordinary service-payment lines.
- Failing to reconcile Schedule M with the CFC ledger. Sales, interest, royalties, services, dividends, and loans should trace to accounting records.
- Completing Schedule M for the wrong category of filer. The IRS specifically assigns Schedule M to Category 4 filers.
A dormant corporation is different. If it qualifies for the Rev. Proc. 92-70 summary procedure and the taxpayer properly elects that procedure, the IRS instructions call for specified page 1 information rather than the full Form 5471 schedule package.
TFX explains that exception further in its guide to dormant foreign corporation reporting.
Based on a common TFX client scenario: intercompany loan between US parent and CFC
Based on our client scenario at TFX: a US shareholder lends $500,000 to a wholly owned CFC during 2025. The maximum amount borrowed from the filer is reported on Schedule M line 32, column (b), while interest paid by the CFC to that filer is reported on line 26, column (b).
Line 32 is not the sum of loan advances during the year. It requires the largest outstanding gross amount borrowed during the year, so a $500,000 peak balance remains the reportable figure even if part of the principal is repaid before December 31.
The following 3 reporting steps apply to this client scenario:
- Reconcile the loan agreement and ledger to identify the largest principal balance outstanding during 2025.
- Enter that peak borrowing on line 32, column (b), because the CFC borrowed from the US person filing the return.
- Report interest the CFC paid to that filer on line 26, column (b), using the Schedule M translation rule if the CFC’s functional currency is not US dollars.
Lines 9 and 11 should not be used for this fact pattern. Line 9 reports tiered hybrid dividends received by the foreign corporation, while line 11 reports interest received by the CFC.
For transfers of property or stock involving foreign corporations, the separate rules in TFX’s IRC section 367 foreign transfer guide may also need review.
Schedule M filing deadlines and extension rules
Schedule M has no separate filing deadline because it is attached to Form 5471, which is filed with the taxpayer’s income-tax return. For a calendar-year individual filing a 2025 Form 1040 in 2026, the regular due date was April 15, 2026, subject to the special overseas and extension rules.
A qualifying US citizen or resident abroad generally received an automatic extension to June 15, 2026, and could request an extension to October 15, 2026, but an extension to file does not generally postpone interest on unpaid tax from the original payment deadline.
A domestic individual filer not qualifying for the automatic overseas extension generally started with the April 15 deadline. Entity filers attach Form 5471 to the entity return whose deadline applies to them.
Schedule M therefore follows the deadline and valid extension of the return carrying Form 5471. The filing date should be considered together with any section 6038 penalty exposure for late or incomplete information reporting.
TFX’s Form 5471 Schedule P guide provides another example of a separate Form 5471 schedule that follows the filer’s return deadline.
Catch up on unfiled Form 5471 returns
Missing Form 5471 filings can span more than 1 tax year, and each annual accounting period of each foreign corporation can carry a separate $10,000 section 6038 penalty exposure. A taxpayer who discovers prior-year omissions should first determine which years, corporations, filer categories, and schedules were actually required.
For qualifying non-willful taxpayers abroad, the TFX Streamlined Filing Procedure service can address delinquent US returns and international information forms when the IRS eligibility rules are met.
How Schedule M relates to foreign tax credit planning
Schedule M does not calculate the foreign tax credit or automatically determine an IRC section 904 basket. For 2025, the tax treatment depends on the underlying income, taxpayer type, source and category rules, and whether sections such as 960 or a section 962 election affect the shareholder’s credit calculation.
Dividends, interest, royalties, and other items reported on Schedule M should be reconciled with the income and foreign-tax records used for the foreign tax credit, but the Schedule M line alone does not determine the credit basket.
An individual claiming direct foreign tax credits generally uses Form 1116. A domestic corporation may instead encounter the section 960 deemed-paid tax rules, while an individual making a section 962 election can have a different set of calculations.
A classification error in the underlying CFC records can therefore produce more than a Schedule M mismatch. It can affect the income amount, source, separate category, deemed-paid tax computation, or carryover used elsewhere on the return.
TFX’s guide to claiming the foreign tax credit on Form 1116 explains the individual credit rules in more detail.
Schedule M for expat business owners: special considerations
US expat business owners with a CFC must separate personal expat-tax benefits from foreign-company reporting. For 2025, claiming the Foreign Earned Income Exclusion on Form 2555 does not remove a Category 4 Form 5471 Schedule M filing obligation, and treaty residence does not automatically eliminate section 6038 reporting.
The Foreign Earned Income Exclusion and Schedule M operate under separate rules, so excluding qualifying salary does not exempt a controlled foreign corporation from required US shareholder reporting.
The following 4 issues deserve separate review for an expat-owned CFC:
- FEIE: Form 2555 can apply to qualifying foreign earned income, but it does not exclude CFC income or erase Form 5471 obligations.
- High-tax CFC income: the GILTI high-tax exception may affect the section 951A calculation when its requirements are met, but it does not by itself cancel Schedule M.
- Treaty positions: a treaty-based position does not automatically override information reporting, and Form 8833 can be required for specified treaty positions.
- Other filer categories: an officer, director, acquiring shareholder, disposing shareholder, or 10%-or-more CFC shareholder may have Category 2, 3, or 5 obligations in addition to Category 4.
For high-tax CFC income specifically, TFX explains the requirements in its GILTI high-tax exception guide.
Section 6038 reporting requirements: the statutory basis for Schedule M
IRC section 6038 is the statutory basis for annual information reporting by a US person that controls a foreign corporation. For 2025, it authorizes ownership, accounting, and transaction reporting, while Schedule M is the IRS mechanism used to report specified transactions between the foreign corporation and the counterparties identified on the schedule.
Section 6038 reporting reaches specified transactions with the filer, controlled entities, and certain 10%-or-more US shareholders, which is why Schedule M separates those counterparties into 5 columns.
The statute also authorizes the $10,000 information-reporting penalty and the separate reduction of foreign taxes otherwise available for credit when required information is not furnished. Those consequences are distinct from the tax that might arise from Subpart F income or section 951A.
Offshore company reporting can also involve FBAR or Form 8938, but those filings answer different questions. Form 5471 reports the foreign corporation; FBAR concerns reportable foreign financial accounts; Form 8938 concerns specified foreign financial assets, subject to its own rules.

Start your Form 5471 filing with TFX
A complete Form 5471 filing can require more than 1 separate schedule, and Schedule M alone contains 34 transaction lines plus 5 counterparty columns. For a US expat business owner, those entries need to tie back to ownership records, CFC accounts, exchange rates, and the other international forms attached to the return.
Frequently asked questions
Form 5471 Schedule M reports specified transactions between a controlled foreign corporation and counterparties listed in columns (b) through (f). Category 4 filers use it for Section 6038 reporting. The schedule covers 34 lines, including sales, services, dividends, interest, loans, and selected receivable or payable balances.
Category 4 filers must file Schedule M under the current Form 5471 instructions. Category 4 generally means a US person controlled the foreign corporation through more than 50% of voting power or value during the relevant period. Category 5 status by itself does not require Schedule M.
The 5471 Schedule M instructions cover specified sales, purchases, services, commissions, rents, royalties, dividends, interest, insurance premiums, loan-guarantee fees, platform and cost-sharing payments, other amounts, and selected loan or trade balances. Each reportable item is assigned to 1 of the 5 counterparty columns.
A section 6038 failure can trigger a $10,000 penalty for each annual accounting period of each foreign corporation. If the failure continues beyond 90 days after IRS notice, another $10,000 can apply for each 30-day period or fraction, with continuation penalties capped at an additional $50,000 per failure.
A dormant foreign corporation can qualify for the summary filing procedure in Rev. Proc. 92-70. When the taxpayer properly uses that procedure, the current Form 5471 instructions direct completion of specified page 1 information rather than the full Schedule M. The corporation must meet the revenue procedure’s dormant-corporation conditions.
Schedule M reports annual related-party transactions for Category 4 filers under section 6038. Schedule O reports organization, reorganization, stock-acquisition, and stock-disposition events under section 6046, with Category 2 and Category 3 filing rules. The 2 schedules cover different facts and can both apply to the same Form 5471.
You can file a late or corrected Form 5471 with Schedule M, but late filing does not guarantee penalty relief. Section 6038 penalties can apply, and reasonable-cause relief depends on the facts. The IRS’s 2026 AEP excludes information reporting dependent on another filing, so filers should not rely on automatic abatement.
For adjacent tested-income reporting, review TFX’s Form 5471 Schedule Q guide. The IRS also provides an accessible version of Schedule M.
