Form 5471 Schedule Q: 2026 complete guide to CFC income by category
Form 5471 Schedule Q reports a controlled foreign corporation’s income, deductions, taxes, and assets by CFC income group.
For a 2025 return filed in 2026, use the published December 2024 Schedule Q with the December 2025 Form 5471 instructions.
The IRS also posted a draft December 2026 Schedule Q on March 18, 2026.
That draft is marked “DRAFT – DO NOT FILE,” so it does not replace the published form used for a 2025 tax year return.
What is Form 5471 Schedule Q?
Schedule Q is a required Form 5471 attachment for Category 4, 5a, and 5b filers.
It reports a CFC’s income, deductions, taxes, and assets by section 904 category and CFC income group for section 960(a) and 960(d) foreign tax calculations. Schedule Q translates a CFC’s tax results into income groups used to determine Subpart F, tested income, and section 960 deemed-paid foreign taxes.
For 2025, the main Line A codes are PAS, 901j, and GEN.
The following 3 points explain what the schedule does and why it matters:
- It captures gross income, allocated deductions, current-year foreign taxes, creditable taxes, asset values, high-tax elections, and loss allocations by income group.
- Category 4, 5a, and 5b filers attach separate Schedules Q when the filing table requires them.
- The IRS introduced separate Schedule Q starting with tax year 2020 to support CFC income-group reporting used in section 960 and Form 1118 computations.
See our TFX Form 5471 guide for the wider foreign-corporation filing rules.
The IRS identifies Schedule Q as the schedule for CFC income, deductions, taxes, and assets by CFC income group.
Background and legislative history of Schedule Q
The IRS introduced separate Schedule Q for tax year 2020 after the TCJA changed CFC inclusion and foreign tax credit rules.
Its 2020 notice tied the schedule to income-group reporting for high-tax rules, Form 1118, and section 960 deemed-paid taxes.
That change sits within the post-TCJA rules for GILTI under section 951A and revised foreign tax credit mechanics.
Read our TFX guide to specified foreign corporations after tax reform for the earlier statutory context.
For 2025 returns filed in 2026, the current rules are revised as of December 2025.
They also reflect OBBBA changes to certain CFC tax years beginning after November 30, 2025, but those later-year changes do not replace the 2025 Schedule Q rules.
Form 5471 penalties can start at $10,000 per foreign corporation for failure to furnish required section 6038 information.
Who must file Schedule Q with Form 5471?
For the 2025 tax year, separate Schedule Q is required for Category 4, Category 5a, and Category 5b Form 5471 filers.
Category 5c filers still exist, but the current IRS filing requirements do not require them to attach Schedule Q.
The following 3 filer categories must be checked against the ownership and attribution rules:
- Category 4: A US person who controlled the foreign corporation, generally through more than 50% of the vote or value at any time during the tax year.
- Category 5a: A section 958(a) US shareholder of a CFC that is not a Category 5b or 5c filer.
- Category 5b: An unrelated section 958(a) US shareholder of a foreign-controlled CFC that meets the Revenue Procedure 2019-40 definition.
Any Category 4, 5a, or 5b filer whose Form 5471 filing table requires Schedule Q must attach it for the relevant CFC.
The Form 5471 Sch. Q filing duty follows the filer category, not the size of the CFC’s income.
Use the TFX expat IRS tax-form checklist to place Form 5471 beside other international forms.
This gives the controlling filer categories and schedule requirements.
That 10% test is different from the more-than-50% control test used for Category 4.
Key definitions you must know before completing Schedule Q
Five definitions control most Schedule Q decisions for a 2025 CFC: CFC, US shareholder, QBU, separate category, and tested income or loss.
A wrong definition can place the same dollar of income in the wrong line, unit, or tax group.
The following 5 terms should be confirmed before preparing the schedule:
- Controlled foreign corporation (CFC): A foreign corporation more than 50% owned by US shareholders by vote or value on any day of its tax year, applying section 958 ownership rules.
- US shareholder: A US person that owns at least 10% of the foreign corporation’s vote or value under section 951(b).
- Qualified business unit (QBU): A separate and clearly identified unit of a trade or business that keeps separate books and records under section 989(a).
- Separate category: An income category used under section 904 to apply the foreign tax credit limitation.
- Tested income or loss: A CFC-level amount computed under section 951A after the statute’s exclusions and properly allocable deductions.
A CFC exists when US shareholders own more than 50% of the corporation’s vote or value on any day of the foreign corporation’s tax year.
These CFC rules are separate from the 3.8% Net Investment Income Tax.
Review our TFX NIIT guide when the shareholder also has investment income that may fall within section 1411.
Purpose of Schedule Q: Income baskets and the foreign tax credit
Schedule Q separates CFC results so section 960 foreign taxes can be matched to the right section 904 category and CFC income group.
For 2025, Line A uses PAS, 901j, or GEN, with a TOTAL Schedule Q required when more than 1 category applies.
A key correction matters here: a CFC does not earn section 951A-category or foreign-branch-category income at the CFC level.
Tested income is generally reported in a tested income group within the general category.
At shareholder level, GILTI inclusion amounts and related deemed-paid taxes are generally treated in the section 951A category.
That is why the Form 5471 Schedule Q instructions must be read with sections 904, 951A, and 960.
Schedule Q supports the income-group and tax-pool data needed for section 960 foreign tax credit calculations; it does not create a separate CFC-level “GILTI basket.”
Capital gains can affect a taxpayer’s broader section 904 position outside Schedule Q.
See our TFX guide to capital gains and losses for the separate US tax treatment of gains and losses.
For 2025, tested income is generally in the GEN category at CFC level, while the shareholder’s GILTI inclusion is generally assigned to the section 951A category.
Schedule Q structure: columns, parts, and lines explained
The 2025 Schedule Q is a 4-page schedule with Lines A–E, income-group Lines 1–5, and 16 columns labeled (i) through (xvi).
It is not divided into “Part I” and “Part II,” and units are reported on sublines rather than separate columns.
The following 4 components make up the schedule:
- Header fields A–E: Category code, passive group when relevant, section 901(j) country, source, and FOGEI or FORI status.
- Lines 1–5: Subpart F groups, recaptured Subpart F income, tested income, residual income, and totals.
- Columns (i)–(xvi): Country, gross income, expenses, taxes, net income, creditable tax, average assets, high-tax status, loss allocation, and net income after loss.
- Unit sublines: QBUs or tested units are listed beneath the relevant income-group line. If more than 2 units must be reported, the IRS requires an expanded computer-generated Schedule Q.
A Schedule Q (Form 5471) review should start at Line A and then trace each unit through Lines 1–4. This catches category errors before totals are carried into Line 5.
How Schedule Q relates to other Form 5471 schedules
Schedule Q works with at least 4 other Form 5471 schedules, but each has a different job.
For tax year 2025, Schedule Q reports CFC income-group tax data, while Schedules H, J, P, and R track E&P, PTEP, and distributions.
The following 4 schedule relationships matter most:
- Schedule J: Tracks accumulated E&P by separate category in the CFC’s functional currency.
- Schedule P: Tracks each US shareholder’s annual PTEP accounts and US dollar basis.
- Schedule H: Computes current E&P or deficit that feeds Schedule J.
- Schedule R: Reports foreign-corporation distributions and links distribution amounts to Schedule J and Schedule P.
Review our TFX Schedule J guide when reconciling accumulated E&P and PTEP categories.
Schedule J and Schedule Q use related category concepts, but their line structures and purposes are different.
Schedule Q provides CFC income-group and foreign-tax detail used in section 960 computations; for a corporate US shareholder, that data can support the Form 1118 foreign tax credit calculation.
A $1 mismatch may be a rounding issue, but a category or E&P mismatch should be traced to its source rather than forced to balance.
Step-by-step instructions for completing Schedule Q
The Form 5471 Schedule Q instructions require a unit-by-unit and income-group analysis before totals are entered.
For 2025, start with the CFC’s category code and tested units or QBUs, then assign income, deductions, foreign taxes, high-tax items, and loss allocations.
The following 7 steps follow the published IRS structure:
- Identify the relevant units. List each tested unit for Line 3 and the required QBU or unit sublines for Subpart F and residual groups.
- Confirm functional currency. Schedule Q amounts are generally prepared in the CFC’s functional currency unless the instructions require US dollars.
- Translate only where required. Column (xii) is specifically reported in US dollars; do not convert every Schedule Q column by default.
- Assign gross income. Put each item in the correct section 904 category and CFC income group.
- Allocate deductions. Apply the section 1.960-1 rules and the relevant section 1.861 allocation rules to expenses.
- Assign foreign taxes. Use section 1.861-20 and section 1.904-6 rules to place current-year foreign taxes in the correct group and determine creditable tax in column (xii).
- Apply Schedule Q loss rules. Use column (xv) for the reduction to Subpart F income when Subpart F income exceeds current-year E&P under Regulations sections 1.952-1(c), 1.952-1(e), and 1.951A-6.
Deduction allocation in columns (iii)–(vii) can change both net income in column (xi) and the foreign tax pool used for section 960.
The instructions for Form 5471 Schedule Q should be applied with the CFC’s books, tax workpapers, and related schedules open together.
That reduces rework when 1 classification affects more than 1 schedule.
Qualified business units (QBUs): the building blocks of Schedule Q
A QBU is a separate and clearly identified unit of a trade or business that keeps separate books and records under section 989(a).
On Schedule Q, QBUs appear on certain sublines, while Line 3 requires tested-unit reporting for the 2025 tax year.
A QBU is not automatically a legal entity.
A branch, division, or disregarded operation can qualify only if it meets the trade-or-business and separate-books requirements.
Based on our client scenario at TFX: a CFC has separately booked operating units in Germany and the Netherlands.
If both qualify as QBUs, the relevant Schedule Q lines identify each unit separately rather than combining both operations into 1 unlabeled total.
A Form 5471 Sch. Q filing should also clearly distinguish QBU reporting from tested-unit reporting.
The IRS requires tested-unit detail for Lines 1a–1j and Lines 3 and 4, with line-specific instructions controlling which unit label is used.
Income baskets on Schedule Q: a practical breakdown
For 2025, Schedule Q Line A has 3 CFC-level category codes – PAS, GEN, and 901j – plus TOTAL when more than 1 category applies.
GILTI and foreign branch are section 904 categories elsewhere, but neither is a CFC-level Line A category for tested income.
For 2025, only 3 Line A category codes apply to a CFC Schedule Q: PAS, GEN, and 901j; GILTI and foreign branch do not get their own CFC-level Line A codes.
| Income category | Schedule Q treatment for a CFC | Key authority |
|---|---|---|
| Passive | Use PAS and the applicable passive-group code on Line B. | IRC §904(d)(1)(A); Reg. §1.904-4(c) |
| General | Use GEN; tested income is generally in a tested income group here. | IRC §904(d)(1)(B); Reg. §1.960-1 |
| Section 901(j) | Use 901j and identify the sanctioned country. | IRC §§901(j), 904(d)(6) |
| Section 951A / GILTI | No CFC-level Line A code; related shareholder inclusions are generally section 951A category. | Reg. §§1.904-4(g), 1.904-6(e) |
| Foreign branch | No CFC-level tested-income group in this category. | IRC §904(d); Form 5471 instructions |
The Schedule Q instructions for Form 5471 use Line A to establish the section 904 category before income-group detail is entered.
Passive income may require multiple Schedules Q because Line B separates passive groups by withholding or foreign tax characteristics.
Deduction allocation and apportionment on Schedule Q
Columns (iii) through (vii) allocate CFC deductions to income groups so Schedule Q can determine net income and the foreign taxes related to each group.
For 2025, the IRS points to Regulations sections 1.960-1(c)(1) and 1.960-1(d)(3)(ii).
Interest expense commonly requires the asset-based rules in Regulations section 1.861-9.
Other deductions follow the section 1.861-8 system and any more specific rule that applies to that expense.
The Schedule Q (Form 5471) instructions also use average asset values in column (xiii) for certain disregarded-payment rules.
Asset classification can affect foreign-tax allocation as well as interest apportionment.
Based on our client scenario at TFX: a CFC has $40,000 of interest expense across 2 income groups.
The preparer allocates the expense under the applicable asset rules before computing each group’s column (xi) net income.
If 2 units use inconsistent average asset values, the interest split and the tax-group results can both be wrong.
Loss allocation on Schedule Q and Treasury Regulation Section 1.861-20(e)
Schedule Q column (xv) does not use Regulations section 1.861-20(e) as its loss-allocation rule.
For 2025, column (xv) reports a Subpart F reduction when Subpart F exceeds current-year E&P under sections 1.952-1(c), 1.952-1(e), and 1.951A-6.
Regulations section 1.861-20(e) serves a different purpose.
It allocates and apportions foreign-law deductions among foreign gross-income groupings when foreign income taxes are assigned for foreign tax credit purposes.
That distinction matters because the same workpaper can contain 2 separate allocation processes.
One allocates foreign-law deductions for foreign-tax grouping; the other records a specific Schedule Q column (xv) Subpart F loss limitation adjustment.
Do not populate it from a generic current section 1.861-20(e) foreign-tax allocation worksheet.
Common mistakes when filing Schedule Q
Six filing errors deserve a specific check on a 2025 Schedule Q: missing unit detail, wrong category codes, omitted tested income, wrong currency handling, deduction errors, and incorrect high-tax or loss entries.
Each filing error affects a specific line or column.
The following 6 mistakes should be checked before filing:
- Omitting a tested unit or required QBU subline.
- Using the wrong Line A category or passive-group code.
- Leaving Line 3 blank when the CFC has a tested income group.
- Translating every amount to US dollars even though most Schedule Q entries remain in functional currency.
- Allocating deductions to the wrong income group.
- Misstating column (xiv) high-tax elections or column (xv) loss allocations.
A Sch. Q (Form 5471) filing can be incomplete even when Form 5471 itself was timely filed.
The IRS requires all requested section 6038 information, and a missing required schedule can expose the filer to Form 5471 penalty rules.
Review our TFX Form 5471 penalty guide if a required schedule was omitted. A $10,000 section 6038(a) penalty can apply per annual accounting period and foreign corporation.
After that notice period, the section 6038 continuation penalty can add $10,000 per 30-day period, up to $50,000 more per failure.
Penalties for failing to file or incorrectly filing Schedule Q
A required but missing Schedule Q can make Form 5471 information incomplete under section 6038.
The base penalty is $10,000 per annual accounting period of each foreign corporation, with added penalties after an IRS notice and a 90-day correction period.
After 90 days, an additional $10,000 applies for each 30-day period or fraction while the failure continues.
The additional section 6038(a) penalty is capped at $50,000 for each failure.
The IRS can also reduce foreign taxes available for credit by 10%, with further 5% reductions for each 3-month continuation period after notice, subject to statutory limits.
A missing Form 5471 information item can also affect the assessment statute under section 6501(c)(8).
The period generally stays open until 3 years after the required information is furnished.
The whole return can be affected unless reasonable-cause rules limit the extension to items related to the missing information.
Reasonable cause and other relief rules are fact-specific.
See our TFX article on penalty relief for Forms 5471, 5472, and 8865 before choosing a correction path.
For 2025, the core Form 5471 section 6038 penalty starts at $10,000, and continued failure after IRS notice can add up to $50,000 more.
Schedule Q vs. Schedule P and Schedule J: understanding the differences
Schedules Q, P, and J answer 3 different Form 5471 reporting questions here.
For 2025, Schedule Q tracks CFC income-group and tax data, Schedule P tracks a shareholder’s PTEP accounts, and Schedule J tracks the foreign corporation’s accumulated E&P.
The 3 schedules should reconcile conceptually, but they do not report the same balances or serve the same filer categories.
| Schedule | Primary purpose | Key IRC reference | Who completes it |
|---|---|---|---|
| Schedule Q | CFC income, deductions, taxes, and assets by CFC income group | §960 | Category 4, 5a, and 5b filers |
| Schedule P | US shareholder annual PTEP accounts and US dollar basis | §§959, 986(c) | Category 1a, 1b, 4, 5a, and 5b filers |
| Schedule J | CFC accumulated E&P by separate category | §§959, 964, 986(b) | Required filer categories under the Form 5471 filing table; 5b and 5c generally have relief for foreign-controlled CFCs |
Schedule P can differ by shareholder when a CFC has more than 1 US shareholder.
Schedule J is a CFC-level E&P schedule, while Schedule Q is an income-group schedule used for section 960 tax computations.
A PTEP difference may be correct when shareholders own different percentages, but an unexplained category mismatch should be resolved in the workpapers.
How Schedule Q feeds into the GILTI calculation
Schedule Q Line 3 reports a CFC’s tested income group, but Form 8992 computes the US shareholder’s GILTI inclusion for the 2025 tax year.
Schedule Q supplies unit-level income and tax detail used in section 960(d), rather than replacing Schedule I-1 or Form 8992.
The IRS requires each tested unit on the Line 3 sublines.
If a GILTI high-tax exclusion applies, the unit’s excluded amounts move into Line 4 totals under the Schedule Q instructions.
For 2025, the high-tax exclusion threshold is an effective foreign tax rate above 90% of the 21% Section 11 corporate rate, or above 18.9%.
The election is made under Regulations section 1.951A-2(c)(7).
Read our TFX article on tax reform and Americans abroad for broader context on the rules that created GILTI.
The Form 5471 Sch. Q instructions still use GILTI terminology for 2025 returns filed in 2026.
Schedule Q Line 3 reports tested-income-group data; the shareholder’s 2025 GILTI inclusion is calculated separately, generally on Form 8992.
A high-tax exclusion can move income and tax from Line 3 detail into Line 4 totals.
Schedule Q and the foreign tax credit: Form 1118 connection
Schedule Q supports section 960(a) and 960(d) deemed-paid foreign tax calculations for corporate US shareholders.
For tax year 2025, a corporate shareholder may use those taxes in its Form 1118 foreign tax credit computation, subject to section 904 limits.
An individual, estate, or trust does not receive the same deemed-paid credit merely because it owns a CFC.
A section 962 election can cause section 951 or 951A inclusions to be treated as received by a corporate US shareholder for section 960 purposes.
Individuals generally use Form 1116 for direct foreign tax credits.
Schedule Q does not automatically flow to Form 1116, so the shareholder’s entity type and any section 962 election must be identified first.
For 2025, Schedule Q is a section 960 input; Form 1118 is the corporate foreign tax credit form, while Form 1116 serves individual direct-credit claims.
Practical tips for gathering the data needed for Schedule Q
Five core data sets usually drive a 2025 Schedule Q filing: unit-level books, foreign tax data, asset values, currency records, and Form 5471 reconciliation schedules.
Gather them before assigning income groups because later corrections can affect several columns at once.
The following 5 records should be ready before preparation begins:
- Trial balances or ledgers for each tested unit and relevant QBU.
- Foreign income tax returns, assessments, and tax-payment records.
- Average asset values needed for column (xiii) and interest apportionment.
- Functional-currency records and the exchange rates required for US-dollar columns.
- Schedule H, Schedule J, Schedule I-1, and related workpapers used to reconcile current E&P and tested income.
Based on our client scenario at TFX: the longest delay came from rebuilding 2 unit-level trial balances after year-end.
Getting those records first allowed the Schedule Q reviewer to trace income, deductions, and taxes without reopening the books.
If the completed US return shows tax due, see our TFX guide to paying US tax from overseas.
Payment mechanics are separate from Schedule Q, but they matter for a 2025 balance due filed in 2026.
A Schedule Q instructions checklist for Form 5471 should also record which figures stay in functional currency.
Only specific fields, such as column (xii), require US-dollar reporting.
Schedule Q filing deadlines and extension rules
Schedule Q has no separate filing deadline; it is attached to Form 5471 and follows the due date of the return with which Form 5471 is filed.
For a calendar-year individual filing a 2025 Form 1040, the regular due date is April 15, 2026.
A qualifying US citizen or resident abroad receives an automatic 2-month extension to June 15, 2026.
If more time is needed, Form 4868 can extend the filing deadline to October 15, 2026.
Taxpayers who are out of the country may request a further discretionary 2-month extension to December 15, 2026.
That request requires a letter to the IRS by October 15; it is not automatic.
An extension to file generally does not erase interest from the original payment due date.
Form 5471 and Schedule Q should be attached to the timely filed or timely extended return.
For a 2025 calendar-year Form 1040, the key 2026 filing dates are April 15, June 15 for qualifying taxpayers abroad, October 15 with Form 4868, and a possible requested extension to December 15.
Frequently asked questions
Schedule Q reports a CFC’s income, deductions, taxes, and assets by CFC income group for section 960(a) and 960(d). It separates data by section 904 category. That grouping supports deemed-paid foreign tax calculations.
This is revised in December 2025. The published Schedule Q used for 2025 filing is revised December 2024.
Category 4, 5a, and 5b filers are the Schedule Q filer categories for 2025. Category 5c is still a Form 5471 category. It is not included in the IRS Schedule Q requirement.
For a CFC, Line A uses PAS, 901j, or GEN.
If more than 1 category applies, a separate TOTAL Schedule Q aggregates the others. GILTI and foreign branch do not receive CFC-level Line A codes.
If Schedule Q is required, omitting it means required section 6038 information was not fully furnished.
The base penalty can be $10,000 per annual period of each foreign corporation. Continuation penalties can also apply after IRS notice.
Line 3 reports the CFC’s tested income group and tested-unit detail.
The shareholder’s GILTI inclusion is calculated separately, generally on Form 8992. Schedule Q supports section 960(d) tax computations tied to tested income.
A QBU is a separate and clearly identified unit of a trade or business with separate books and records under section 989(a).
Schedule Q also uses tested-unit reporting. The 2 labels are not interchangeable.
Yes. The IRS says to file a corrected Form 5471 with an amended return, mark it “Corrected,” and attach a statement identifying the changes. The correction route depends on the facts.
See our TFX Form 14457 Voluntary Disclosure Practice guide when willfulness or disclosure issues may be present. A non-willful case may call for a different IRS compliance route.
Content is educational and is not legal or tax advice. Form 5471 results can change with ownership, entity type, foreign taxes, elections, and filing history.
