A midsize parent had been filing Schedule A for three years running when the math started to drift. The controller never noticed the group crossed into consolidated status once a domestic subsidiary was added, so the consolidated GILTI computation had quietly been wrong on every return since. We rebuilt the workpaper from each CFC's Schedule I-1 of Form 5471, pulled clean tested income, tested loss, and QBAI into Part I, and reran the computation as a single group-level number.

Schedule B (Form 8992) is the consolidated-group GILTI worksheet, filed only by U.S. consolidated groups whose members are U.S. shareholders of one or more CFCs. Pull tested income or loss from Schedule I-1 Line 6, QBAI from Line 8, tested interest expense from Line 9d, and tested interest income from Line 10c, converting to dollars as required. Use the December 2022 revision for 2025, and apply the stop rule early: if column (h) tested loss equals or exceeds column (g) tested income, you stop after Form 8992 Part I.

Key Takeaways

You prepare one Schedule B for the entire consolidated group, then complete a consolidated Form 8992. Member level Forms 8992 are prepared for records, not filed.
In Part I, list every CFC with the exact EIN or Form 5471 reference ID and every §958(a) 10% U.S. shareholder with EIN. Populate tested income or loss, QBAI, and interest items.
Apply the stop rule fast. If Part I total in column (h), tested loss, equals or exceeds column (g), tested income, you stop after Form 8992 Part I, line 3.
If column (g) is greater than column (h), complete columns (i) through (n) and all of Part II, then build owner Forms 8992 and the consolidated Form 8992.
Pull tested income or loss from Schedule I‑1 Line 6, QBAI from Line 8, tested interest expense from Line 9d, and tested interest income from Line 10c, converting to U.S. dollars as required.

What Schedule B is and when it applies

Schedule B functions like a master control sheet for a consolidated group. You use it when any member is a U.S. shareholder of a CFC within §958(a); non-consolidated U.S. shareholders do not use Schedule B – they file Schedule A of Form 8992 instead. Part I captures the CFC roster, owners, and the key amounts from each CFC’s Schedule I‑1. Part II converts those amounts into shareholder level allocations that carry to each owner’s Form 8992, then to the group’s consolidated Form 8992.

How the stop rule decides your path

Total Part I columns, then compare column (h) tested loss to column (g) tested income.

If column (h) equals or exceeds column (g), you stop. Enter the column (g) and (h) totals on Form 8992 Part I, lines 1 and 2, compute line 3, and you are done.
If column (g) is greater, continue through columns (i) through (n) and complete Part II.

Who must appear on Schedule B

Every CFC owned within §958(a) by any group member, identified with the exact EIN or the exact Form 5471 reference ID used on the I‑1.
Each §958(a) 10% U.S. shareholder, with name and EIN, tied to the correct CFC line.

The critical link to Form 8992

Schedule B drives two outputs. First, each U.S. shareholder completes its own Form 8992 using the Schedule B Part II allocations. Second, you aggregate those owner forms line by line to prepare the consolidated Form 8992 that gets filed with Schedule B. If the stop rule hits, the consolidated Form 8992 stops after Part I, line 3.

Pulling the right data from Form 5471 Schedule I‑1

Key I‑1 lines you actually use

Line 6, tested income or tested loss, drives Part I columns (e) and (f) (enter tested losses as parenthesized, negative values in column (f); reporting them as positives inverts the consolidation math and misstates GILTI).
Line 8, QBAI for tested income CFCs, feeds the QBAI components used for DTIR.
Line 9d, tested interest expense, and Line 10c, tested interest income, feed the specified interest build. Convert functional currency amounts to U.S. dollars using the average rate.

Matching identifiers is non‑negotiable

Your Schedule B identifiers must mirror Form 5471. Use the same EIN or the same reference ID that appears on the I‑1. This one to one match is what keeps pro rata shares from double counting when a CFC appears on more than one line for different owners.

Roles and responsibilities at a glance

Who	What appears	Why it matters
CFCs	Name, EIN or reference ID	Establishes scope of tested items
U.S. shareholders	Names and EINs	Drives correct pro rata allocations
QBAI amounts	Part I and Part II	Determine DTIR and the stop decision
Common parent	Consolidated filer	Files Schedule B and consolidated 8992

Complete one Schedule B for the group, then file it with the consolidated return. Provide a copy to each member.

Pro tip, lock your tie out early, then run the stop rule before you invest time in Part II. It saves review hours and reduces rework.

Ownership and pro rata shares that stand up in review

Compute once, reconcile everywhere

Identify each §958(a) 10% U.S. shareholder for every CFC line, then report that owner’s pro rata share of tested income or loss, QBAI, and tested interest items in the designated columns. Part I columns for owners must reconcile to the CFC level totals so the same CFC is not counted twice.

Aggregate without double counting

When you roll up tested income and tested loss for the group, total each CFC’s amounts once, even if that CFC appears on multiple lines. The instructions explicitly caution against reflecting the same CFC more than once in the Part I totals. That is how you keep Form 8992 Part I lines 1 and 2 clean and the stop rule accurate.

Specified interest, then DTIR, then GILTI

The interest pipeline you must trace

Pull tested interest expense from I‑1 Line 9d and tested interest income from Line 10c.
Record the CFC level amounts and each owner’s pro rata share in Part I.
In Part II, sort and sum across the group to get consolidated tested interest expense and income, then compute consolidated specified interest expense, floored at zero, and allocate it back to owners.

Building DTIR the right way

For each owner, DTIR equals 10% of that owner’s share of consolidated QBAI, reduced by its share of consolidated specified interest expense. The math happens on Schedule B, then carries into each owner’s Form 8992 and finally to the consolidated Form 8992, unless you stopped after line 3.

Step by step, start to file

A quick path you can follow under pressure

Complete Part I columns (a) through (h) for all CFCs and owners.
Total Part I, then apply the stop rule using columns (g) and (h).
If continuing, complete columns (i) through (n) and all of Part II.
Build owner Forms 8992 from Part II.
Aggregate to the consolidated Form 8992 and file it with Schedule B.

Map to the I‑1, then lock the tie out

Every tested figure on Schedule B must trace back to Schedule I‑1. Use Line 6 for tested income or loss, Line 8 for QBAI, Line 9d for tested interest expense, and Line 10c for tested interest income. Convert to U.S. dollars using the average annual rate and keep the exchange proofs.

Common pitfalls that drain partner time

Misclassifying group members

Missing an owner, misreading §958(a), or mismatching EINs will ripple through Part I and Part II. Confirm each owner meets the 10% test, belongs in the group, and is listed on the right CFC lines for the inclusion year. Reconcile the sum of the owners’ tested income or loss back to each CFC’s Line 6.

Incomplete intercompany eliminations

Intercompany items can inflate tested income, QBAI, or tested interest. Scrub transfers that duplicate depreciable basis and remove intercompany interest pairs before you populate the specified interest columns, or DTIR will be distorted. Anchor every adjustment to documented eliminations.

Wrong pro rata allocations

Use ownership for the inclusion year and carry four decimal precision in your workpapers to avoid rounding drift, then keep those percentages tied to the exact CFC identifiers on Schedule B. Do not compute DTIR or specified interest if the stop rule says stop.

High tax exclusion and the 18.9% threshold

What “high taxed” means for GILTI

The elective GILTI high tax exclusion can remove items from gross tested income if the effective foreign tax rate on a tested unit exceeds 90% of the section 11 rate. With a 21% corporate rate, the threshold is 18.9%. The final regulations apply the election at the tested unit level and set out consistency rules. Keep the effective rate workpapers with your Schedule B file.

How the election changes Schedule B

If you elect the exclusion for a CFC inclusion year and an item qualifies, you exclude that item from gross tested income on Form 5471 and reflect zero tested income for that item when you compile Schedule B. That changes Part I totals, which can flip the stop rule, and it changes DTIR downstream. Maintain consistent identifiers and retain your tested unit computations.

Keep an eye on policy changes that affect section 11 or section 250, since they shift the math behind high tax and the size of the section 250 deduction. Model year by year and document your assumptions.

Section 250 on Form 8993, where GILTI becomes deductible

Your Form 8992 result flows into Form 8993 to compute the section 250 deduction and any taxable GILTI after the income limitation. For tax years beginning on or after January 1, 2018 and before January 1, 2026, corporations generally deduct 50% of GILTI; the 2025 tax year still falls under the GILTI regime (IRC §951A), not the OBBBA-renamed Net CFC Tested Income (NCTI) framework, which applies only to tax years beginning after December 31, 2025. After that, OBBBA amendments change the deduction percentage and related rules. Confirm your year open date and track changes.

Practical tips for Form 8993 alignment

Confirm Form 8992 GILTI ties exactly to the amount carried into Form 8993.
Test the taxable income limitation and note any haircut.
Keep a short memo in the file that shows the percentage used and the authority for the year.

Filing deadlines, extensions, and timing that prevents fire drills

A calendar year C corporation files by the 15th day of the fourth month after year end. If the due date falls on a weekend or legal holiday, you file on the next business day.
A timely Form 7004 generally grants an automatic 6 month extension. Special 7 month rules apply to certain June 30 year ends through specific transition periods, so check your facts.
An extension gives you time to file, not time to pay. Interest and penalties apply to unpaid tax even if you extend.

If you stopped after line 3 because column (h) equaled or exceeded column (g), you still file Schedule B with the consolidated Form 8992 to preserve the outcome.

Recordkeeping that stands up to questions

Build a file your reviewers will love

Complete Form 5471 packages for each CFC, including Schedule I‑1 with exchange rate proofs.
A Schedule B tie out that cross references every Part I and Part II figure to I‑1 Lines 6, 8, 9d, and 10c.
QBAI basis schedules using ADS, with average basis computations and support for dual use property.
Part II interest workings showing consolidated expense, consolidated income, specified interest, and allocation back to owners.

Amending when numbers change

When to correct

Amend if an error changes net tested income, DTIR, specified interest, or any Schedule B totals that affect a shareholder’s GILTI. Fix upstream Form 5471 first, then rerun Schedule B and Form 8992, and update Form 8993 if needed. Observe the statute and include a short explanation.

How to course correct without more headaches

Reconfirm identifiers, rebuild Part I totals, and retest the stop rule.
Recompute Part II allocations, then each owner’s Form 8992, then the consolidated Form 8992.
If a high tax election is involved, confirm timing and attach the tested unit workpapers that support the effective rate.

A practical checklist for every close

The 9 point “no rework” flow

Identify all §958(a) 10% U.S. shareholders and all CFCs with exact EINs or reference IDs.
Pull I‑1 Lines 6, 8, 9d, and 10c, convert to U.S. dollars, and log exchange proofs.
Complete Part I columns (a) through (h), total, and test the stop rule.
If continuing, complete columns (i) through (n) and all of Part II.
Build owner Forms 8992 from Part II.
Aggregate to the consolidated Form 8992 and file it with Schedule B.
Prepare the section 250 computation on Form 8993 with the correct year percentage.
Confirm due dates and file Form 7004 if you need time. Remember, extension to file is not extension to pay.
Archive the tie out and note any high tax election decisions with tested unit proofs.

Common Mistakes We See Every Season

The same handful of Schedule B (Form 8992) errors land in our review pile every consolidated season. Each one traces back to either treating Schedule B like Schedule A, or skipping the Schedule I-1 (Form 5471) source step.

1. Filing Schedule A when the group is consolidated. When a parent and one or more subsidiaries file a consolidated Form 1120, the U.S. shareholder of any CFC is the consolidated group, not the individual member. Filing Schedule A for each member instead of one Schedule B for the group inverts the single-entity math under Treas. Reg. §1.1502-51 and triggers IRS notice traffic. Fix: Before you start, confirm consolidated-group status from the parent's Form 1120 election. If the group files consolidated, the only correct schedule is Schedule B; Form 8992 with Schedule B attaches to the consolidated parent's return.

2. Entering tested losses as positive numbers. Part I columns (f), (h), and (j) plus Part II columns (e) and (f) all require parenthesized (negative) values for tested loss, pro rata share of tested loss, tested-loss QBAI, aggregate tested loss, and allocable share of consolidated tested loss. Flipping any of these to positive inflates consolidated tested income and over-states the GILTI inclusion. Fix: Lock a workpaper template that auto-formats every loss column in parentheses, and tie the totals back to each CFC's Schedule I-1 (Form 5471) before posting to Schedule B.

3. Including tested-loss CFC QBAI in consolidated QBAI. Only QBAI of tested-income CFCs feeds consolidated QBAI on Part II column (g). Tested-loss CFC QBAI is reported as a parenthesized amount in Part I column (j) and reduces the consolidated QBAI base. Folding it in the wrong direction overstates the Deemed Tangible Income Return and understates GILTI. Fix: Run a two-line tie-out: sum positive QBAI from tested-income CFCs into column (g), then reduce by the parenthesized tested-loss QBAI from column (j) before computing DTIR.

4. Computing specified interest expense at the CFC level. Consolidated specified interest expense (Part II column (l)) is a group-level number: the excess of consolidated tested interest expense over consolidated tested interest income, never below zero. Building it CFC by CFC and summing produces a different answer and breaks the DTIR computation that follows. Fix: Sum Part II columns (j) and (k) first, then take the positive excess of (j) over (k) as column (l). If (k) is greater than or equal to (j), specified interest expense is zero.

5. Writing numbers directly on Schedule B without Schedule I-1. Part I columns (e), (f), (i), (k), and (m) are pulled from each CFC's Schedule I-1 (Form 5471) for the same tax year. Computing tested income, tested loss, QBAI, tested interest expense, or tested interest income directly on Schedule B bypasses the source schedule and leaves no audit trail for review. Fix: Prepare Schedule I-1 of Form 5471 for every CFC first, then post the I-1 totals into Schedule B Part I with a column-by-column tick-and-tie reference back to the source schedule.

6. Using 2026 (OBBBA) terminology on a 2025 return. For tax year 2025 the regime is still called GILTI under IRC §951A and the 50% §250 deduction still applies to corporate shareholders. The OBBBA rename to Net CFC Tested Income (NCTI) and the related rate changes apply only to tax years beginning after December 31, 2025. Fix: Keep 2025 workpapers and the consolidated Form 8992 cover in GILTI / §250 terminology, and queue a separate NCTI / OBBBA workpaper template for tax years beginning on or after January 1, 2026.

Reusable Checklists

Copy these into your firm SOP before the consolidated close. The checkboxes save state in the reader's browser, so a preparer can step through prep and a senior can re-walk the same list at review.

Consolidated GILTI pre-close packet

Confirm the consolidated-group election on Form 1120 and list every member that is a U.S. shareholder of a CFC.
List every CFC by name, EIN or reference ID, and tax year end, with the U.S. shareholder member name and EIN attached.
Collect each CFC's prior-year Schedule I-1 (Form 5471) and the current-year functional-currency trial balance.
Tag each CFC as tested-income or tested-loss for the year before any pro rata share work begins.
Flag any CFC with a high-tax exclusion election under IRC §951A so it is excluded from the GILTI base from the start.
Note any subsidiary acquisition, disposition, or §338 election in the year that affects consolidated-group composition.

Schedule I-1 to Schedule B Part I reconciliation

Tick tested income from each CFC's Schedule I-1 (Form 5471) into Part I column (e).
Tick tested loss into Part I column (f) as a parenthesized (negative) value.
Apply each U.S. shareholder member's pro rata percentage to columns (g), (h), (i), (j), (l), and (n).
Confirm tested-loss QBAI sits in column (j) in parentheses and reduces consolidated QBAI, not adds to it.
Compute the GILTI allocation ratio in column (o) using only positive tested income as the denominator.
Cross-foot Part I Row 1 (Totals) to the supporting CFC-level workpaper before moving to Part II.

DTIR, specified interest, and §250 deduction review

Sum consolidated tested interest expense in Part II column (j) and consolidated tested interest income in column (k).
Set Part II column (l) to the excess of (j) over (k); enter zero if (k) is greater than or equal to (j).
Compute consolidated QBAI in column (g) using only tested-income CFC QBAI, then allocate to each shareholder member in column (h).
Compute DTIR as 10% of consolidated QBAI minus the allocable share of consolidated specified interest expense, per IRC §951A(b)(2).
Carry each corporate shareholder's GILTI inclusion to Form 8993 and confirm the 50% §250 deduction before posting to the consolidated Form 1120.
Document any §962 election separately for non-corporate U.S. shareholders outside the consolidated group itself.

Keep 8992 Schedule B Season From Stalling

Consolidated GILTI work hits hardest in the weeks before the consolidated Form 1120 filing deadline. The same parent that closes its books in March often does not finish allocating tested income, tested loss, QBAI, and specified interest across CFC members until late in the cycle, which leaves Schedule B (Form 8992) sitting on a senior reviewer's desk while extensions, §250 deduction tie-outs on Form 8993, and other international compliance work compete for the same partner hours.

The fix is not more hours. It is a workpaper that walks Part I to Part II in one direction, with every CFC-level number tied back to Schedule I-1 (Form 5471) and every consolidated computation tied back to Treas. Reg. §1.1502-51. When the source schedules feed Schedule B cleanly, the reviewer is checking signs and pro rata shares, not rebuilding the math from scratch.

Anchor the workpaper to Schedule I-1 (Form 5471) tested income, tested loss, QBAI, and interest figures for every CFC before any Part I column is filled.
Format Part I columns (f), (h), and (j) plus Part II columns (e) and (f) so tested-loss and tested-loss QBAI values stay parenthesized, never positive.
Compute consolidated specified interest expense once at the group level (Part II column (l) = excess of (j) over (k), floor zero), then push the allocable share to column (m).
Build DTIR as 10% of consolidated QBAI minus allocable share of specified interest, sourced from tested-income CFCs only.
Hand off to Form 8993 with the 50% §250 deduction already proven for each corporate shareholder member, so the consolidated Form 1120 has nothing left to recompute.

That is the layered review discipline our U.S. tax outsourcing team runs on every consolidated GILTI engagement, so partners spend their time on positions and elections rather than tying Part I back to Part II at the last hour.

FAQs

How do foreign currency moves affect Schedule B?

They change tested income, QBAI, and interest components when you convert functional currency amounts to U.S. dollars and when exchange gains or losses flow through the tested unit. Use the average exchange rate for I‑1 Lines 6 through 10c and keep the conversion calculations.

Can I e‑file with a large Schedule B attachment?

Yes. You can file a computer generated Schedule B if it conforms to the IRS version and you expand it as needed. Provide a copy to each member and file Schedule B with the consolidated return.

How are partial year acquisitions or dispositions handled?

Prorate ownership for the inclusion year and ensure the right owners are listed on the right CFC lines for the portion of the year they owned stock. Keep acquisition and disposition dates in the tie out so Part I and Part II numbers reflect the correct owners.

How does Schedule B link to the section 250 deduction?

When Form 8992 is complete, its GILTI result flows to Form 8993 for the section 250 deduction. Through years beginning before January 1, 2026, corporations generally deduct 50% of GILTI, subject to the income limitation.
